## Title
Multi-enterprise video conference service

## Abstract

A system is configured to receive a request to set up a first video conference and another request to set up a second video conference, where the request is received from a client device and where the other request is received from another client device; obtain first information associated with an enterprise with which the client device is associated and second information associated with another, different enterprise with which the other client device is associated; determine whether the first information permits the client device to set up the first video conference and whether the second information permits the other client device to set up the second video conference; establish the first video conference when the first information permits the client device to set up the first video conference; and establish the second video conference when the second information permits the other client device to set up the second video conference.

## Background
BACKGROUND
Users, of user devices, have a growing array of networks and/or service providers from which to obtain video conferencing services. The user devices may be associated with an enterprise, such as a business, an organization, etc., that subscribes to the video conference services so that the user devices can access and utilize the video conference services. The user devices usually access the video conferencing service by calling a telephone number, utilizing a string, and/or accessing a website, and providing login credentials. When the login credentials are verified, the user devices are connected to a communication bridge via which the video conference services can be accessed by the user devices. The video conferencing services may allow users, of the user devices, to interact, on a real-time basis, with other users in a virtual multi-media environment associated with streaming voice, video, messaging, etc.
Unfortunately, the video conferencing services may allow users, that have acquired the login credentials and which are not authorized to attend the video conference, to access the video conference service. Allowing unauthorized users to access the video conference may permit confidential information associated with the enterprise to be disclosed to the unauthorized users.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
The following detailed description refers to the accompanying drawings. The same reference numbers in different drawings may identify the same or similar elements.
A system and/or method, described herein, may allow a video communication and/or conference system (VCCS), originally designed to enable a client device associated with an enterprise to hold video conferences, to set up and/or establish multiple distinct virtual environments that can be accessed by client devices associated with multiple different enterprises. Each distinct virtual environment may allow users, of respective client devices, to interact in a secure manner and/or from potentially geographically distributed locations. The VCCS may establish each of the virtual environments using public access points and/or connections (e.g., using a non-secure, generic, and/or publically accessible protocol, etc.), secure access points and/or connections (e.g., using a secure protocol, such as a tunneling protocol, a virtual private network (VPN), etc.), based on respective client information that specifies access control, call routing, communication and/or security protocols, etc. for each of the virtual environments. The VCCS may segregate virtual environments so that information, from within one virtual environment, cannot be access via another virtual environment. Establishing multiple virtual environments may enable the VCCS to provision a video conferencing service to multiple different enterprises, which may allow users, of the client devices, to communicate via a video conference while avoiding the expense associated with traveling to meetings.
A system and/or method may allow the VCCS to dynamically determine whether to permit a client device to access a virtual environment based on client information. The VCCS may, based on the client information, block a user from setting up a virtual environment that provides access to a user that is not authorized, by the client information, to access the virtual environment. A system and/or method may allow the VCCS to dynamically set up a virtual environment, on a near real-time basis, if the client information permits the user to set up the virtual environment.
FIG. 1 is a diagram of an example environment 100 in which systems and/or methods described herein may be implemented. As shown in FIG. 1, environment 100 may include a group of client devices 110-1, . . . , 110-M (where M≧1), a group of client communication servers 120-1, . . . , 120-N (where N≧1) (hereinafter referred to collectively as “client servers 120” and individually as “client server 120”), a video communication and/or conference system (VCCS) 130, and a network 140. The number of systems, equipment, or servers, illustrated in FIG. 1, is provided for explanatory purposes only. In practice, there may be additional systems, equipment, or servers; fewer systems, equipment, or servers; different systems, equipment, or servers; and/or differently arranged systems, equipment, or servers than illustrated in FIG. 1.
Also, in some implementations, one or more of the devices and/or servers of environment 100 may perform one or more functions described as being performed by another one or more of the devices and/or servers of environment 100. Devices of environment 100 may interconnect via wired connections, wireless connections, or a combination of wired and wireless connections.
Client device 110 may include one or more devices that is capable of communicating with network 140. For example, client device 110 may include a desktop computer, a radiotelephone, a personal communications system (PCS) terminal (e.g., that may combine a cellular radiotelephone with data processing and data communications capabilities), a personal digital assistant (PDA) (e.g., that can include a radiotelephone, a pager, Internet/intranet access, etc.), a laptop computer, a tablet computer, a camera, a personal gaming system, a smart phone, or another type of computation and/or communication device.
Client device 110 may, for example, use a camera to take a picture and/or record video that client device 110 can transmit, as an image and/or video content, respectively, to VCCS 130 via network 140 and/or client server 120. Client device 110 may also, or alternatively, include a microphone that is capable of recording sound, such as words spoken by a user of client device 110, that client device 110 can transmit, as audio content, to VCCS 130 via network 140 and/or client server 120. Client device 110 may transmit, to VCCS 130, a media stream of traffic that includes the image, the video content, the audio content, and/or other content (e.g., message content, data, etc.).
Client device 110-1 may be associated with an enterprise (e.g., shown as a dotted rectangle labeled as “Enterprise A”) and may communicate with other client devices (not shown in FIG. 1), associated with the enterprise, via client communication server 120-1 associated with the enterprise. The enterprise may be associated with a first private network (e.g., a local area network (LAN), a wide area network (WAN), etc.) located, for example, within an office where the enterprise conducts business. Client device 110-1 and/or client communication server 120-1 may be connected to the first private network. Assume that client device 110-3 is also associated with the enterprise and is not directly connected to the first private network.
Client device 110-2 may be associated with another enterprise (e.g., shown as a dotted rectangle labeled as “Enterprise B”) and may communicate with other client devices (not shown in FIG. 1), associated with the other enterprise, via client communication server 120-N associated with the other enterprise. The other enterprise may be associated with a second private network located, for example, within an office where the other enterprise conducts business. Client device 110-2 and/or client communication server 120-N may be connected to the second private network. Assume that client device 110-M is also associated with the other enterprise and is not directly connected to the second private network.
Client server 120 may include one or more server devices, or other types of computation and/or communication devices, that gather, process, search, store, and/or provide information in a manner described herein. In one example, client server 120 may receive, process, and/or transmit traffic, such as voice, video, text, and/or other data associated with a virtual environment set up by a user of client device 110. Client server 120 may maintain an authorized client list (e.g., a white list) of client devices 110 and/or users of client devices 110 that are permitted, by an operator of client server 120, to access and/or utilize a video conference service that is provisioned by VCCS 130. Client server 120 may also, or alternatively, maintain an unauthorized client list (e.g., black list) of other client devices 110 and/or users of the other client devices 110 that are not permitted, by the operator, to access the video conference service. Client server 120 may transmit the authorized client list and/or the unauthorized client list to VCCS 130. Client server 120 may transmit, to VCCS 130, an updated authorized and/or unauthorized client list when changes are made to the authorized and/or unauthorized client list, respectively.
VCCS 130 may include one or more devices that gather, process, search, store, and/or provide information in a manner similar to that described herein. VCCS 130 may be capable of communicating with client devices 110 and/or client servers 120 via network 140. VCCS 130 may perform operations associated with setting up, establishing, or terminating one or more virtual environments via which a video conference service is provisioned to client devices 110.
Network 140 may include one or more wired and/or wireless networks. For example, network 140 may include a cellular network, the Public Land Mobile Network (PLMN), a public switched telephone network (PSTN), and/or a second generation (2G) network, a third generation (3G) network, a fourth generation (4G) network, a fifth generation (5G) network, and/or another network (e.g., a long term evolution (LTE) network). Additionally, or alternatively, network 160 may include a wide area network (WAN), a metropolitan area network (MAN), an ad hoc network, an intranet, the Internet, and/or a combination of these or other types of networks.
FIG. 2 is a diagram of example components of VCCS 130. VCCS 130 may include a video communication server 210, a video controller 220, and/or a conference module 230. In another implementation, VCCS 130 may include additional components, fewer components, different components, or differently arranged components than are shown in FIG. 2.
Video communication server 210 may include one or more server devices, or other types of computation and/or communication devices, that gather, process, search, store, and/or provide information in a manner described herein. Video communication server 210 may be capable of communicating, via network 140, with client server 120 and/or client device 110. Video communication server 210 may also, or alternatively, be capable of communicating with video controller 220 and/or conference module 230.
In one example, video communication server 210 may receive, process, and/or transmit traffic, such as voice, video, text, and/or other data associated with a virtual environment via which a conference (e.g., a video conference, a telephone conference, etc.) is to be set up and/or conducted. Video communication server 210 may also, or alternatively, communicate using a variety of transport and/or signaling protocols (e.g., a streaming protocol, an IP, a telepresence interworking protocol (TIP), etc.) that allow video communication server 210 to communicate with a variety of types of client servers 120 (e.g., Cisco Unified Call Manager (CUCM), etc.) and/or client devices 110 (e.g., Cisco Telepresence System (CTS), etc).
Video communication server 210 may, for example, communicate with client server 120 to obtain client information associated with one or more enterprises (e.g., enterprise A, enterprise B, etc.). The client information, for a particular enterprise, may generally identify which client devices 110 are authorized to access and/or utilize a video conferencing service being provisioned by VCCS 130 and/or which client devices 110 are not authorized to access and/or utilize the video conference service. Video communication server 210 may provide the client information to video controller 220.
Video communication server 210 may also, or alternatively, receive a request, from client device 110, to set up a virtual environment via which to hold a conference. Video communication server 210 may forward the request for processing to video controller 220. Based on an indication, received from video controller 220, that client device 110 is authorized to set up the virtual environment, video communication server 210 may instruct conference module 230 to establish a bridge to which one or more client devices 110 can connect to attend the conference. Additionally, or alternatively, video communication server 210 may receive a request, from another client device 110, to access the conference and may forward a request to video controller 220 to determine whether the other client device 110 is authorized to access the bridge associated with the conference. Video communication server 210 may receive, from video controller 220, an indication that client device 110 is authorized to access the conference and may forward the request to conference module 230 to establish a connection between client 110 and the bridge. Video communication server 210 may not forward the request to conference module 230 based on an indication that the other client device 110 is not authorized to access the conference.
Video controller 220 may include one or more server devices, or other types of computation and/or communication devices, that gather, process, search, store, and/or provide information in a manner described herein. In one example, video controller 220 may be capable of communication with video communication server 210 and/or conference module 230. Video controller 220 may receive, from video communication server 210, client information associated with one or more enterprises (e.g., enterprise A, enterprise B, etc.). Video controller 220 may store the client information in a memory associated with VCCS 130.
Video controller 220 may also, or alternatively, receive, from video communication server 210, set up information associated with a request to set up a conference. The set up information may generally identify which client device 110 is to participate in the conference, a time at which the conference is to occur, etc. Video controller 220 may determine whether a user, of client device 110 from which the request originated, is authorized to set up the conference based on client information associated with an enterprise with which the user is associated. Video controller 220 may transmit, to video communication server 210, an indication of whether client device 110 is authorized to set up the conference.
Video controller 220 may also, or alternatively, determine whether users, of other client devices 110, are authorized to access the conference by determining whether the other client devices 110 are authorized by the set up information and/or is not precluded from accessing the conference by the client information. Video controller 220 may transmit, to video communication server 210, an indication of whether the other client devices 110 are authorized to attend the conference.
Conference module 230 may include one or more devices that are capable of creating a bridge associated with a conference (e.g., a video conference, a telephone conference, etc.), between client devices 110. The bridge may permit multiple client devices 110 to be connected to create a virtual environment in which to conduct a conference where each client device 110 can communicate with other client devices 110 connected to the bridge. Conference module 230 may create the bridge based on set up information received from video communication server 210 and/or video controller 220. Conference module 230 may, allocate resources to allow the bridge to be set up, such as a quantity of ports, associated with the bridge, based on a quantity of client devices 110 identified by the set up information. Conference module 230 may also, or alternatively, schedule a period of time, identified by the set up information, during which resources (e.g., bandwidth, processing and/or switching capacity, etc.) are to be allocated for the bridge. Conference module 230 may receive, from video communication server 210, a request to access the bridge, associated with client device 110, and may connect client device 110 to the bridge. Conference module 230 may provide services associated with the bridge, such as audio and/or video recordings, text transcriptions, etc. Conference module 230 may terminate the conference at a time identified by the set up information, which may cause client device 110 to be disconnected from the bridge.
FIG. 3 is a diagram of example components of a device 300 that may correspond to client device 110, client server 120, video communication server 210, video controller 220, and/or conference module 230. Alternatively, each of client device 110, client server 120, video communication server 210, video controller 220, and/or conference module 230 may include one or more devices 300 and/or one or more components of device 300. Device 300 may include a bus 310, a processor 320, a memory 330, an input component 340, an output component 350, and a communication interface 360. In another implementation, device 300 may include additional components, fewer components, different components, or differently arranged components than are shown in FIG. 3.
Bus 310 may include a path that permits communication among one or more of the components of device 300. Processor 320 may include a processor, microprocessor, or processing logic that may interpret and execute instructions. Memory 330 may include any type of dynamic storage device that may store information and instructions for execution by processor 320, and/or any type of non-volatile storage device that may store information for use by processor 320.
Input component 340 may include a mechanism that permits a user to input information to device 300, such as a keyboard, a keypad, a pointing device, a button, a switch, etc. Output component 350 may include a mechanism that outputs information to the user, such as a display, a speaker, one or more light emitting diodes (LEDs), etc. Communication interface 360 may include any transceiver-like mechanism that enables device 300 to communicate with other devices and/or systems. For example, communication interface 360 may include an Ethernet interface, an optical interface, a coaxial interface, or the like.
As will be described in detail below, device 300 may perform certain operations relating to provisioning a video conference service. Device 300 may perform these operations in response to processor 320 executing software instructions contained in a computer-readable medium, such as memory 330. A computer-readable medium may be defined as a non-transitory memory device. A memory device may include space within a single physical memory device or spread across multiple physical memory devices. The software instructions may be read into memory 330 from another computer-readable medium or from another device. The software instructions contained in memory 330 may cause processor 320 to perform processes described herein. Alternatively, hardwired circuitry may be used in place of or in combination with software instructions to implement processes described herein. Thus, implementations described herein are not limited to any specific combination of hardware circuitry and software.
FIG. 4 is a diagram of an example data structure 400 that stores client information associated with an enterprise. Data structure 400 may be stored in a memory associated with client server 120 and/or VCCS 130. Data structure 400 may include a collection of fields, such as, for example, an enterprise field 410, a client server identifier (ID) field 415, a client device ID field 420, a user information (info) field 425, a privilege level field 430, a type field 435, and an access field 440. The quantity of fields, within data structure 400, is provided for explanatory purposes. In another implementation, there may be additional fields, fewer fields, different fields, or differently arranged fields than are shown in FIG. 4.
Enterprise field 410 may store information that identifies an enterprise (e.g., a company name, identifier, etc.) with which a particular client device 110 is associated. Client server ID field 415 may store information associated with client server 120 (e.g., an IP address, a uniform resource locator (URL), a uniform resource identifier (URI), a media access control (MAC) address, etc.) via which the particular client device 110, associated with the enterprise, communicates with video communication server 210. Client device ID field 420 may store information associated with the particular client device 110, such a device identifier (e.g., a mobile directory number, a landline directory number, etc.), an address (e.g., an IP address, a URL, a URI, a MAC address, etc.), information associated with a type of client device 110 (e.g., a computer, a mobile device, a CTS, etc.), etc. Client device ID field 420 may also, or alternatively, store information associated with a type of encryption that the particular client device 110 is capable of using.
User info field 425 may store information associated with a user of the particular client device 110 (e.g., a name, a home address, a business address, a username, password, personal identification number (PIN), etc.).
Privilege level field 430 may store information that identifies a privilege level associated with the user of the particular client device 110. The privilege level may, for example, identify whether the user is authorized to access a video conference service, being provisioned by VCCS 130, to set up a conference and/or to invite users of other client devices 110, associated with the enterprise, to the conference. Additionally, or alternatively, the privilege level may identify whether the user is authorized to invite users, of other client devices 110, to attend a conference (e.g., a conference set up by the user) that are not associated with the enterprise and/or are associated with a different enterprise.
Type field 435 may store information that identifies whether the user is an internal user associated with the enterprise, an external user associated with the enterprise, or a user that is not associated with the enterprise or is associated with a different enterprise (e.g., a partner of the enterprise, a competitor of the enterprise, etc.). For example, an internal user may be associated with client device 110 that is directly connected to a private network associated with an enterprise and/or with communication server 120 associated with the enterprise. An external user may be associated with client device 110 that communicates indirectly with the private network and/or communication server 120 (e.g., via network 140 and/or another communication server 120 associated with a different enterprise).
Access field 440 may store information that identifies whether the user and/or the particular client device 110 is authorized to attend a conference that is set up by another user of a different client device 110.
For example, an operator, of client server 120, may enter client information, associated an enterprise, into data structure 400 (e.g., via a user interface, retrieved from a memory, obtained from another server device, etc.) that identifies users, of client devices 110, that are authorized to access a video conference service provisioned by VCCS 130. In one example, data structure 400 may store client information that identifies the enterprise (e.g., A), client server 120 associated with the enterprise (e.g., 120-1), and/or information associated with first client device 110 associated with the enterprise (e.g., CE1) (e.g., as shown by ellipse 442). Data structure 400 may also, or alternatively, store information associated with a first user (e.g., user1) of the first client device 110, a privilege level of the first user (e.g., high), and an indication (e.g., internal) that the first client device 110 is connected to a private network (e.g., a LAN, WAN, etc.) associated with the enterprise (e.g., as shown by ellipse 442). Data structure 400 may also, or alternatively, store information that identifies whether first client device 110 is permitted to attend a video conference (e.g., yes) (e.g., as shown by ellipse 442). A high privilege level may indicate that the first user is authorized to invite a user associated with external client device 110 that is not connected to the private network and/or that is associated with another enterprise.
Additionally, or alternatively, data structure 400 may store client information associated with second client device 110 (e.g., CE2) that is associated with the enterprise (e.g., A), but is outside of and/or not connected to (e.g., external) the private network associated with the enterprise (e.g., as shown by ellipse 444). Second client device 110 may also be authorized to access the video conference service (e.g., yes) (e.g., as shown by ellipse 444). Data structure 400 may also, or alternatively, store information that identifies a privilege level (e.g., standard) that permits the second user to set up a conference that internal and/or external client device 110, associated with the enterprise, are permitted to attend, but not external client device 110 that are not associated with the enterprise (e.g., as shown by ellipse 444).
Data structure 400 may also, or alternatively, store client information associated with a third user (e.g., user3), of third client device 110 (e.g., CE3) associated with another enterprise (e.g., partner B), that is authorized to access the video conference service (e.g., yes) (e.g., as shown by ellipse 446). The third user may, for example, correspond to an employee, associated with the other enterprise, that is authorized to work on a project with employees of the enterprise. Third client device 110 may be authorized to access the video conference service, via another client server 120 (e.g., 120-M) associated with the other enterprise, that is external to the private network (e.g., external) (e.g., as shown by ellipse 446).
Data structure 400 may also store client information associated with users (e.g., user4, user5, etc.) and/or client device 110 (e.g., CE4, CE5, etc.) that are not authorized to access the video conference service (e.g., no) and/or have a privilege level that indicates that the users are not authorized to set up a conference (e.g., none) (e.g., as shown by ellipses 448 and 450). The users may be associated with the enterprise (e.g., A) and/or the other enterprise (e.g., partner B) (e.g., as shown by ellipses 448 and 450).
FIG. 5 is a flow chart of an example process 500 for obtaining or updating client information associated with an enterprise, according to an implementation described herein. In one implementation, process 500 may be performed by VCCS 130. In another implementation, some or all of process 500 may be performed by a device or collection of devices separate from, or in combination with, VCCS 130.
As shown in FIG. 5, process 500 may include receiving an instruction to obtain client information associated with an enterprise (block 505) and obtaining, from a client server associated with an enterprise, the client information (block 510). For example, VCCS 130 may receive an instruction, from an operator of VCCS 130 and/or based on an occurrence of some event (e.g., based on a predetermined time interval, a time of day, etc.), to obtain client information associated with one or more enterprises that have subscribed to a video conference service provisioned by VCCS 130. VCCS 130 may, as a result of the instruction, transmit, to client server 120 associated with an enterprise, a request for client information associated with the enterprise. Client server 120 may receive the request and may provide the client information to VCCS 130.
In another example, client server 120 may provide, to VCCS 130, the client information without receiving the request from VCCS 130. Client server 120 may, for example, automatically, or in response to an instruction from an operator of client server 120, provide the client information to VCCS 130. In one example, the operator, of client server 120, may enter client information, associated with the enterprise, into a data structure (e.g., data structure 400 of FIG. 4) for the first time and may instruct client server 120 to transmit the client information to VCCS 130. Additionally, or alternatively, client server 120 may access a website hosted by VCCS 130 and/or a database to which VCCS 130 has access. VCCS 130 may obtain the client information via the website (e.g., via web page associated with the website) and/or by accessing the database and retrieving the client information from the database.
The client information may include a respective first entry for each client device 110 that is authorized to use and/or access a video conference service that is provisioned by VCCS 130 and/or a respective second entry for each client device 110 that is not authorized to use and/or access the video conference service. In another example, the operator, of client server 120, may update the client information (e.g., by adding or removing entries from the client information) and may cause client server 120 to transmit, to VCCS 130, the updated client information. VCCS 130 may receive the client information from client server 120.
Process 500 may include comparing the client information to other client information that is stored in the memory (block 515) and storing, in the memory, client information that does not match other client information that is stored within the memory (block 520). For example, VCCS 130 may compare the client information, received from client server 120, to other client information stored within a memory associated with VCCS 130. Based on a determination, that the received client information does not match the other client information, VCCS 130 may store the client information in the memory associated with VCCS 130. In another example, VCCS 130 may determine that one or more entries, associated with one or more client devices 110 and within the received client information, does not match any entries of the other client information. Based on the determination that the one or more entries do not match any of the entries of the other client information, VCCS 130 may associate, within the memory, the one or more entries with the other client information.
Process 500 may include removing, from the memory, other client information that is not included within the client information (block 525) and may transmit, to the client server, a notification that identifies client information stored and/or other client information removed from the memory (block 530). For example, VCCS 130 may determine that one or more entries, within the other client information associated with the enterprise and stored within the memory, does not match any entries of the received client information. Based on the determination that the one or more entries, within the other client information, does not match any of the entries of the received client information, VCCS 130 may erase, overwrite and/or otherwise remove, from the memory, the one or more entries that do not match any of the entries associated with the received client information.
VCCS 130 may transmit a notification, to client server 120, that indicates that the client information has been stored within the memory. The notification may identify the one or more entries that were associated, within the memory, with the other client information. Additionally, or alternatively, the notification may identify the one or more entries, associated with the other client information, that were removed from the memory.
FIG. 6 is a flow chart of an example process 600 for setting up a multi-party conference, according to an implementation described herein. In one implementation, process 600 may be performed by VCCS 130. In another implementation, some or all of process 600 may be performed by a device or collection of devices separate from, or in combination with, VCCS 130.
As shown in FIG. 6, process 600 may include receiving, from a client device associated with an enterprise, a request to set up a conference (block 605) and obtaining, from the client device, set up information associated with the conference (block 610). For example, a user of client device 110 may access VCCS 130 to set up a video conference to be attended by one or more other client devices 110. In one example, client device 110 may access a website hosted by VCCS 130 and the user may enter, via a web page associated with the website, set up information associated with the conference. VCCS 130 may receive the set up information via the web page. In another example, client device 110 may communicate with client server 120 and the user may provide the set up information to client server 120 (e.g., via a user interface, etc.). Client server 120 may transmit the set up information to VCCS 130 and VCCS 130 may receive, from client server 120, the set up information.
The set up information may include information that identifies the user (e.g., a username, password, personal identification number, etc.), client device 110 (e.g., device identifier, MDN, IP address, MAC address, etc.), an enterprise with which client device 110 is associated (e.g., an enterprise name, identifier, etc.), client server 120 (e.g., a device identifier, IP address, MAC address, etc.), one or more other client devices 110 that are to attend the conference, one or more enterprises with which the other client devices 110 are associated, and/or one or more users of the other client devices 110. The set up information may also, or alternatively, identify a time period (e.g., a start time, an end time, an expected duration, etc.) during which the conference is to be held; features to be enabled during the conference, such as streaming video, streaming audio, generation of a video and/or audio recording of the conference, generation of a text transcript of the conference, applications to be used during the conference (e.g., a word processing application, a presentation application, etc.); and/or other set up information.
Process 600 may also include retrieving client information associated with the enterprise (block 615) and identifying, based on the set up information, client devices that are to access the conference (block 620). For example, VCCS 130 may retrieve, from a memory associated with VCCS 130 (e.g., from data structure 400 of FIG. 4), client information associated with the enterprise identified by the set up information. In another example implementation, VCCS 130 may communicate with client server 120, identified by the set up information, to obtain the client information. Additionally, or alternatively, VCCS 130 may, based on the set up information, identify each client device 110 that is permitted to access the conference.
If an identified client device is not authorized to attend the conference (block 625—NO), then process 600 may include transmitting a notification that the identified client device is not authorized to attend the conference (block 630). For example, VCCS 130 may determine whether client device 110, from which the set up information was received, is authorized to set up the conference by identifying whether a privilege level, specified by the client information and associated with the user of client device 110, is less than a threshold. Based on a determination that the privilege level is less than the threshold, VCCS 130 may transmit a notification, to client device 110, that the user is not authorized to set up the conference. If, however, VCCS 130 determines that the privilege level, associated with the user, is not less than the threshold, VCCS 130 may determine whether other client devices 110, identified by the set up information, are authorized to attend the conference based on the client information.
VCCS 130 may, for example, determine whether the client information, associated with client devices 110 identified by the set up information, authorizes the identified client device 110 to attend the conference. Based on a determination that the client information does not include an indication that the identified client device 110 is authorized to attend the conference, VCCS 130 may transmit a notification, to client device 110, indicating that the identified client device 110 is not authorized to attend the conference. In this example, VCCS 130 may determine that the identified client device 110 is not identified in a list of client devices 110 (e.g., a white list) that are authorized to attend a conference.
Additionally, or alternatively, the client information may indicate that identified client device 110 is not capable of communicating using an encryption scheme identified by the client information. Based on the indication that the identified client device 110 is not capable of communicating using the encryption scheme, VCCS 130 may not permit the identified client device 110 to attend the conference and/or may transmit a notification, to client device 110, indicating that the identified client device 110 is not authorized to attend the conference.
Additionally, or alternatively, based on a determination that the identified client device 110 is not authorized to attend the conference, VCCS 130 may transmit a notification, to client device 110, indicating that the identified client device 110 is not authorized to attend the conference. In this example, VCCS 130 may determine that the identified client device 110 is not authorized to attend the conference when the identified client device 110 is identified in a list (e.g., a black list) of client devices 110 that is not authorized to attend a conference and/or is associated with another enterprise that is not authorized to attend the conference.
Additionally, or alternatively, VCCS 130 may transmit the notification that the identified client device 110 is not authorized to attend the conference when VCCS 130 determines that a privilege level, associated with the user of client device 110, does not permit client device 110 to set up a conference with identified client device 110 associated with another enterprise and/or that is external to and/or not connected to a LAN/WAN associated with the enterprise.
If an identified client device is authorized to attend the conference (block 625-YES), then process 600 may include generating conference information to set up the conference based on the set up information (block 635). For example, VCCS 130 may determine that client device 110, from which the set up information was received, is authorized to set up the conference based on a determination that the privilege level, specified by the client information, is not less than the threshold and/or matches a particular level.
Additionally, or alternatively, VCCS 130 may determine that the identified client device 110 is authorized to attend the conference based on a determination that the identified client device 110 is identified in the list of client devices 110 (e.g., the white list) that are authorized to attend the conference.
Additionally, or alternatively, VCCS 130 may determine that the identified client device 110 is authorized to attend the conference based on a determination that the privilege level, associated with the user of client device 110, permits client device 110 to set up a conference with identified client devices 110 associated with another enterprise and/or that is external to and/or not connected to a LAN/WAN associated with the enterprise.
Additionally, or alternatively, VCCS 130 may determine that the identified client device 110 uses the encryption scheme identified by the client information and may permit the identified client device 110 to attend the conference based on the determination that identified client device 110 uses the encryption scheme.
Based on the determination that the user is authorized to set up the conference and/or that the identified client device 110 is authorized to attend the conference, VCCS 130 may generate conference information to be used to establish the conference. VCCS 130 may, for example, schedule the conference based on the time period identified by the set up information. Additionally, or alternatively, VCCS 130 may allocate resources for the scheduled conference based on a quantity of client devices 110 that are to attend the conference, such as bandwidth resources (e.g., for some or all client devices 110), ports via which client devices 110 are to access the conference, an address associated with the conference (e.g., an IP address, a URL, etc.), a telephone number associated with the conference, and/or access information with which to access the conference (e.g., login information, such as a username, password, PIN, etc.), etc.
VCCS 130 may also, or alternatively, obtain, from the client information, information associated with identified client device 110, such as a respective device identifier (e.g., an MDN, a LDN, etc.), a respective address (e.g., an IP address, a MAC address, etc.), information associated with a respective user of identified client device 110 (e.g., a username, password, PIN, etc.), information associated with an encryption scheme used by the identified client device 110, etc. VCCS 130 may also, or alternatively, obtain, from the client information, information associated with a particular client server 120 via which identified client device 110 is to access the conference (e.g., a device identifier, an address, etc.).
Process 600 may further include transmitting a notification to identified client devices that are authorized to attend the conference (block 640) and establishing a conference bridge based on the conference information (block 645). For example, VCCS 130 may transmit a notification to identified client devices 110 that are authorized to attend the conference. In one example, the notification may correspond to an invitation to attend the conference that identifies a time at which the conference is to start, a telephone number to be called to access the conference, a destination address (e.g., an IP address, a URL, etc.) to be used to communicate with VCCS 130 to attend the conference, etc. Additionally, or alternatively, the invitations may include login information (e.g., a username, a password, a PIN, etc.) to be used by the users of the identified client devices 110 to access the conference.
VCCS 130 may establish a conference bridge, associated with the conference, for the time period identified by the conference information. VCCS 130 may, for example, establish the conference bridge by allocating the bandwidth and/or assigning the ports, to the conference bridge, that were specified by the conference information. VCCS 130 may also, or alternatively, associate the telephone number, the destination address, and/or the login information to the conference bridge that allows the identified client devices 110 to access the conference bridge during the time period. VCCS 130 may allow each identified client device 110 to communicate with the conference bridge based on the telephone number and/or the destination address. VCCS 130 may also, or alternatively, establish a connection, via a respective port, between each identified client device 110 and the conference bridge, when the login information is received from each of the identified client devices 110 and/or is verified by VCCS 130. Establishing the connection to the conference bridge may permit each identified client device 110 to communicate with all or a portion of other identified client devices 110 that have established the connection to the conference bridge.
FIG. 7 is a flow chart of an example process 700 for establishing a connection between a client device and a conference bridge. In one implementation, process 700 may be performed by VCCS 130. In another implementation, some or all of process 700 may be performed by a device or collection of devices separate from, or in combination with, VCCS 130.
As shown in FIG. 7, process 700 may include receiving a request to access a conference (block 705) and retrieving conference information associated with the conference (block 710). For example, a user, of client device 110, may cause client device 110 to transmit a request, to VCCS 130, to access a conference that was set up by VCCS 130 in a manner similar to that described above with respect to process 600 of FIG. 6. VCCS 130 may receive the request and may analyze one or more packets (e.g., packet headers, trailers, labels, payloads, etc.), associated with the request, to identify a conference bridge, associated with the conference, to be accessed by client device 110. In one example, VCCS 130 may obtain, from the packets, a destination address (e.g., a URL, an IP address, etc.), a telephone number, an identifier, etc. that corresponds to the conference bridge. VCCS 130 may, in response to the request, retrieve, from a memory associated with VCCS 130, conference information that corresponds to the conference identified by the request.
Process 700 may also include identifying the client device from which the request was received (block 715). For example, VCCS 130 may analyze one or more packets, associated with the request, to identify client device 110 from which the request was received. VCCS 130 may, for example, identify within the packets (e.g., within the packet header, trailer, label, payload, etc.), a source address (e.g., an IP address, a MAC address, a URI, etc.), information associated with a user (e.g., username, password, PIN, etc.), a device identifier (e.g., a MDN, a LDN, etc.), etc. associated with client device 110. Additionally, or alternatively, VCCS 130 may identify, from the packets, an address associated with client server 120 (e.g., an IP address, a URI, a MAC address, etc.) via which the request, from client device 110, was received. VCCS 130 may identify client device 110 based on the information, associated with client device 110, obtained from the packets.
If the client device is not authorized to access the conference (block 720—NO), then process 700 may include transmitting a notification that the client device is not authorized to access the conference (block 725). For example, VCCS 130 may determine whether client device 110 is authorized to access the conference based on the conference information and information obtained from the packets. In one example, VCCS 130 may determine that information associated with client device 110 (e.g., the source address) does not match any of the information associated with client device 110 included within the conference information. Based on a determination that the information, associated with the client device 110, does not match any information associated with client device 110 included within the conference information, VCCS 130 may transmit a notification, to client device 110, indicating that client device 110 is not authorized to attend the conference.
Additionally, or alternatively, VCCS 130 may determine that information that identifies the conference (e.g., a destination address, etc.), obtained from the packets, does not correspond to a conference bridge that client device 110 is authorized to attend. Based on the determination that the information that identifies the conference does not correspond to a conference bridge that client device 110 is authorized to attend, VCCS 130 may transmit a notification, to client device 110, indicating that client device 110 is not authorized to attend the conference.
Additionally, or alternatively, VCCS 130 may determine that login information (e.g., a username, password, PIN, etc.), associated with the request to access the conference, does not match login information, associated with the conference and identified within the conference information. Based on the determination that the login information does not match login information, associated with the conference and identified within the conference information, VCCS 130 may transmit a notification, to client device 110, indicating that client device 110 is not authorized to attend the conference.
If the client device is authorized to access the conference (block 720—YES), then process 700 may include establishing a connection between the client device and the conference bridge associated with the conference (block 730). For example, VCCS 130 may determine that information, associated with client device 110 (e.g., the source address), matches information, associated with client device 110, included within the conference information. Based on a determination that the information, associated with the client device 110, matches the information, associated with client device 110 included within the conference information, VCCS 130 may connect client device 110, via a port identified by the conference information, to a conference bridge associated with the destination address.
Additionally, or alternatively, VCCS 130 may determine that information that identifies the conference (e.g., based on the destination address, etc.) corresponds to the conference bridge that client device 110 is authorized to attend. Based on the determination that the information that identifies the conference corresponds to the conference bridge that client device 110 is authorized to attend, VCCS 130 may connect client device 110 to the conference bridge.
Additionally, or alternatively, VCCS 130 may determine that the login information matches login information, associated with the conference and identified within the conference information. Based on the determination that the login information matches the login information, associated with the conference and identified within the conference information, VCCS 130 may connect client device 110 to the conference bridge.
FIG. 8 is a diagram of an example of concurrent conferences within an example portion 800 environment 100. As illustrated in FIG. 8, example environment portion 800 may include a group of client devices 110-1, 110-2, 110-3, and 110-M; client servers 120-1 and 120-N; and VCCS 130. Client devices 110-1, 110-2, 110-3, and 110-M; client servers 120-1 and 120-N; and VCCS 130 may include the features described above in connection with FIG. 1 and/or FIG. 2.
As shown in FIG. 8, example portion 800 represents concurrent conferences being hosted by VCCS 130. The concurrent conferences may include a first multi-party conference (e.g., represented by the circles labeled as “1”) (hereinafter referred to as “first conference”) between two or more client devices 110 (e.g., client device 110-1 and 110-3) and a second multi-party conference (e.g., represented by the circles labeled as “2”) (hereinafter referred to as “second conference”) between two or more other client devices 110 (e.g., client device 110-2 and 110-M).
Each of the concurrent conferences may be set up in a manner similar to that described above with respect to process 600 of FIG. 6. For example, VCCS 130 may establish the first conference based on first set up information, received from first client device 110 (e.g., first client device 110-3), and/or client information associated with a first enterprise (e.g., enterprise A), received from first client server 120 (e.g., first client server 120-1). Additionally, or alternatively, VCCS 130 may establish the second conference based on second set up information, received from second client device 110 (e.g., second client device 110-M), and/or client information associated with a second enterprise (e.g., enterprise B), received from second client server 120 (e.g., second client server 120-N). In this example, the first conference may be established for a first period of time that occurs during all or a portion of a second period of time during which the second conference is established.
First client device 110 may be associated with the first enterprise and may, in a manner similar to that described above with respect to process 700 of FIG. 7, access the first conference by communicating, via first client server 120, with VCCS 130 and/or providing login credentials (e.g., as shown by the left-pointing arrows labeled as “1”) that permit VCCS 130 to connect first client device 110 to a first conference bridge associated with the first conference. Third client device 110 (e.g., third client device 110-1) may, in a manner similar to that described above with respect to process 700 of FIG. 7, access the first conference by communicating with VCCS 130 and/or providing login credentials (e.g., as shown by the right-pointing arrow labeled as “1”) that permit VCCS 130 to connect third client device 110 to the first conference bridge.
Connecting first client device 110 and/or third client device 110 to the first conference bridge may permit first client device 110 and third client device 110 to communicate via the first conference bridge in a secure manner (e.g., as shown by shaded block arrows labeled as “1”). The shaded block arrows may represent secure connections (e.g., associated with a tunneling protocol, a virtual private network, etc.) that do not allow traffic, transmitted via the first conference bridge, to be received from and/or transmitted to client device 110 that is not connected, or authorized to be connected, to the first conference bridge. Additionally, or alternatively, information used to set up and/or establish the first conference (e.g., the set up information, the client information, and/or conference information) may be stored and/or handled, by VCCS 130, in a manner that does not allow the information used to set up and/or establish the first conference to be received from and/or transmitted to client device 110, that is not connected, or authorized to be connected, to the first conference bridge.
Second client device 110 may be associated with the second enterprise and may, in a manner similar to that described above with respect to process 700 of FIG. 7, access the second conference by communicating, via second client server 120, with VCCS 130 and/or providing login credentials (e.g., as shown by the left-pointing arrows labeled as “2”) that permit VCCS 130 to connect second client device 110 to a second conference bridge associated with the second conference. Fourth client device 110 (e.g., fourth client device 110-2) may, in a manner similar to that described above with respect to process 700 of FIG. 7, access the second conference by communicating with VCCS 130 and/or providing login credentials (e.g., as shown by the right-pointing arrow labeled as “2”) that permit VCCS 130 to connect fourth client device 110 to the second conference bridge.
Connecting second client device 110 and/or fourth client device 110 to the second conference bridge may permit second client device 110 and/or fourth client device 110 to communicate via the second conference bridge in a secure manner (e.g., as shown by block arrows labeled as “2”). The block arrows may, in a manner similar to that described above, represent secure connections that do not allow traffic, transmitted via the second conference bridge, to be received from and/or transmitted to client device 110 that is not connected, or authorized to be connected, to the second conference bridge. Additionally, or alternatively, information used to set up and/or establish the second conference may be stored and/or handled, by VCCS 130, in a manner that does not allow the information used to set up and/or establish the second conference to be received from and/or transmitted to client device 110, that is not connected, or authorized to be connected, to the second conference bridge.
FIG. 9 is a flow chart of an example process for setting up a conference on a just-in-time basis. In one implementation, process 900 may be performed by VCCS 130. In another implementation, some or all of process 900 may be performed by a device or collection of devices separate from, or in combination with, VCCS 130.
As shown in FIG. 9, process 900 may include receiving a request to set up a conference on a near real-time basis (block 905) and obtain set up information associated with the conference (block 910). For example, a user of client device 110 may access VCCS 130 to set up a video conference on a just-in-time basis. For example, setting up the video conference on the just-in-time basis may correspond to setting up the video conference on a near real-time basis and/or an on-the-fly basis as client devices 110 attempt to access the video conference. VCCS 130 may, for example and in response to the request, obtain set up information from client device 110. For example, VCCS 130 may, in a manner similar to that described above with respect to block 605 of FIG. 6, obtain set up information, associated with the just-in-time conference, from client device 110 via a web page (e.g., associated with a website hosted by VCCS 130), a user interface (e.g., via client server 120), etc.
The set up information may include information that identifies the user (e.g., a username, password, personal identification number, etc.), client device 110 (e.g., device identifier, MDN, IP address, MAC address, etc.), an enterprise with which client device 110 is associated (e.g., an enterprise name, identifier, etc.), client server 120 (e.g., a device identifier, IP address, MAC address, etc.), etc. The set up information may also, or alternatively, identify that the conference is to be established on a just-in-time basis; features to be enabled during the conference, such as streaming video, streaming audio, generation of a video and/or audio recording of the conference, generation of a text transcript of the conference, applications to be used during the conference (e.g., a word processing application, a presentation application, etc.); and/or other set up information.
Process 900 may also include establishing a conference bridge based on the set up information and client information associated with an enterprise (block 915) and connecting the client device to the conference bridge (block 920). For example, VCCS 130 may, based on the set up information, identify an enterprise with which client device 110 is associated. VCCS 130 may also, or alternatively, retrieve, from a memory associated with VCCS 130, client information associated with the enterprise.
VCCS 130 may, in a manner similar to that described above with respect to block 625 of FIG. 6, determine whether client device 110 is authorized to access a conference based on whether client device 110 is identified in a list of client devices 110, within the client information, that are approved to access a conference. Based on an indication that client device 110 is not identified in the list of client devices 110 that are approved to access a conference, VCCS 130 may not permit client information 110 to set up and/or access the just-in-time conference. In another example, VCCS 130 may permit client information 110 to set up and/or access the just-in-time conference based on an indication that client device 110 is identified in the list of client devices 110 that are approved to access a conference.
Additionally, or alternatively, VCCS 130 may, in a manner similar to that described above with respect to block 625 of FIG. 6, determine whether a user, of client device 110, is authorized to set up the just-in-time conference based on whether a privilege level, associated with the user and identified by the client information, is greater than a threshold. Based on a determination that the privilege level is less than the threshold and/or matches a particular level, VCCS 130 may not set up the just-in-time conference. In another example, VCCS 130 may determine that the user is authorized to set up the just-in-time conference based on a determination that the privilege level is not less than the threshold and/or matches a different particular level.
VCCS 130 may establish a conference bridge, associated with the just-in-time conference, based on the determination that the user is authorized to set up the just-in-time conference. VCCS 130 may, for example, allocate resources for the conference bridge, such as bandwidth resources for client device 110, a port via which client device 110 is to be connected to the conference bridge, an address associated with the conference (e.g., an IP address, a URL, etc.), a telephone number associated with the conference, and/or access information with which to access the conference (e.g., login information, such as a username, password, PIN, etc.), etc. VCCS 130 may connect client device 110 to the conference bridge via the port associated with the conference bridge.
Process 900 may further include receiving, from another client device, a request to access the conference (block 925) and verifying that the other client device is authorized to access the conference (block 930). For example, other client device 110 may transmit, to VCCS 130, a request to access the just-in-time conference. VCCS 130 may receive the request and may analyze one or more packets, associated with the request, to obtain information associated with the other client device 110. The information associated with other client device 110 may, for example, include a source address (e.g., an IP address, a MAC address, a URL, etc.), a device identifier (e.g., MDN, LDN, etc.), etc. VCCS 130 may also, or alternatively, analyze the packets to identify a destination address (e.g., a URL, URI, etc.) for the conference bridge associated with the just-in-time conference. The other client device 110 may, in one example, have receive the destination address, associated with the conference bridge, from VCCS 130 and/or client device 110 as a result of establishing the conference bridge.
VCCS 130 may determine whether the other client device 110 is identified (e.g., based on the source address, the device identifier, etc.) in the list of client devices 110, within the client information, that are authorized to attend a conference. Based on a determination that the other client device 110 is not identified within the list of client devices 110 that are authorized to access a conference, VCCS 130 may transmit a notification to other client device 110 indicating that the other client device 110 is not authorized to attend the just-in-time conference.
If, however, VCCS 130 determines that other client device 110 is identified within the list of client devices 110 that are authorized to access a conference, VCCS 130 may authorize the other client device 110 to access the conference bridge.
Process 900 may include allocating resources, to the conference bridge, for the other client device (block 935) and connecting the other client device 110 to the conference bridge (block 940). For example, based on the determination that the other client device 110 is authorized to access the just-in-time conference, VCCS 130 may allocate other resources to the conference bridge associated with the just-in-time conference. For example, VCCS 130 may allocate another port, to the conference bridge, via which other client device 110 is to be connected to the conference bridge. Additionally, or alternatively, VCCS 130 may allocate additional bandwidth and/or processing resources, to the conference bridge, to permit the other client device 110 to communicate via the conference bridge. Based on the allocation of the other resources to the conference bridge, VCCS 130 may establish a connection, via the other port, between the other client device 110 and the conference bridge.
In one example, VCCS 130 may determine, based on the client information, that the other client device 110 is a particular type of client device 110 (e.g., a CTS and/or some other type of client device 110) and/or is communicating via a particular type of client server 120 (e.g., a CUCM and/or some other type of client server). Based on the determination that the other client device 110 is the particular type of client device 110 and/or is communicating via the particular type of client server 120, VCCS 130 may retrieve, from a memory associated with VCCS 130, a signaling template. The signaling template may permit VCCS 130 to communicate with a variety of types of client devices 110 and/or client servers 120 using a variety of transport and/or signaling protocols (e.g., a streaming protocol, an IP, a TIP, etc.). VCCS 130 may use the signaling template to establish the connection between the other client device 110 and the conference bridge so that the other client device 110 is able to transmit traffic to and/or receive traffic from client device 110 via the conference bridge.
A system and/or method, described herein, may allow a VCCS, originally designed to enable a client device associated with an enterprise to hold video conferences, to set up and/or execute multiple distinct video conferences that can be accessed by client devices associated with multiple different enterprises. Each distinct video conference may allow users, of respective client devices, to interact in a secure manner and/or from potentially geographically distributed locations. The VCCS may establish each of the video conferences, using secure connections, based on respective client information that specifies access control, call routing, communication and/or security protocols, etc. for each of the video conferences. The VCCS may process information associated with video conferences so that information, associated with one video conference cannot be accessed via another video conference. Establishing multiple video conferences may enable the VCCS to provision a video conferencing service to client devices associated with multiple different enterprises, which may allow users, of the client devices, to hold meetings without the enterprises incurring the expense associated with users traveling to meetings or purchasing their own equipment.
A system and/or method may allow the VCCS to dynamically determine whether to permit a client device to access a virtual environment based on client information. The VCCS may, based on the client information, block a user from setting up a video conference that provides access to a user that is not authorized, by the client information, to access the video conference. A system and/or method may allow the VCCS to dynamically set up a video conference, on a just-in-time basis, if the client information permits the user to set up the video conference.
The foregoing description provides illustration and description, but is not intended to be exhaustive or to limit the implementations to the precise form disclosed. Modifications and variations are possible in light of the above disclosure or may be acquired from practice of the implementations.
While series of blocks have been described with regard to FIGS. 5-7 and 9, the order of the blocks may be modified in other implementations. Further, non-dependent blocks may be performed in parallel.
It will be apparent that systems and/or methods, as described above, may be implemented in many different forms of software, firmware, and hardware in the implementations illustrated in the figures. The actual software code or specialized control hardware used to implement these systems and/or methods is not limiting of the implementations. Thus, the operation and behavior of the systems and/or methods were described without reference to the specific software code—it being understood that software and control hardware can be designed to implement the systems and/or methods based on the description herein.
Further, certain portions, described above, may be implemented as a component or logic that performs one or more functions. A component or logic, as used herein, may include hardware, such as a processor, an application-specific integrated circuit (ASIC), or a field-programmable gate array (FPGA), or a combination of hardware and software (e.g., a processor executing software).
It should be emphasized that the term “comprises/comprising,” when used in this specification, is taken to specify the presence of stated features, integers, steps or components but does not preclude the presence or addition of one or more other features, integers, steps, components or groups thereof.
Even though particular combinations of features are recited in the claims and/or disclosed in the specification, these combinations are not intended to limit the disclosure of the possible implementations. In fact, many of these features may be combined in ways not specifically recited in the claims and/or disclosed in the specification. Although each dependent claim listed below may directly depend on only one other claim, the disclosure of the implementations includes each dependent claim in combination with every other claim in the claim set.
No element, act, or instruction used in the present application should be construed as critical or essential to the implementations unless explicitly described as such. Also, as used herein, the article “a” is intended to include one or more items. Where only one item is intended, the term “one” or similar language is used. Further, the phrase “based on” is intended to mean “based, at least in part, on” unless explicitly stated otherwise.
