FIG. 1 depicts an illustrative embodiment of a first communication system 100 for delivering media content. The communication system 100 can represent an Internet Protocol Television (IPTV) broadcast media system. The IPTV media system can include a super head-end office (SHO) 110 with at least one super headend office server (SHS) 111 which receives media content from satellite and/or terrestrial communication systems. In the present context, media content can represent audio content, moving image content such as videos, still image content, or combinations thereof. The SHS server 111 can forward packets associated with the media content to video head-end servers (VHS) 114 via a network of video head-end offices (VHO) 112 according to a common multicast communication protocol.
The VHS 114 can distribute multimedia broadcast programs via an access network 118 to commercial and/or residential buildings 102 housing a gateway 104 (such as a common residential or commercial gateway). The access network 114 can represent a group of digital subscriber line access multiplexers (DSLAMs) located in a central office or a service area interface that provide broadband services over optical links or copper twisted pairs to buildings 102. The gateway 104 can use common communication technology to distribute broadcast signals to media processors 106 such as Set-Top Boxes (STBs) which in turn present broadcast channels to media devices 108 such as computers or television sets managed in some instances by a media controller 107 (such as an infrared or RF remote control).
The gateway 104, the media processors 106, and media devices 108 can utilize tethered interface technologies (such as coaxial or phone line wiring) or can operate over a common wireless access protocol. With these interfaces, unicast communications can be invoked between the media processors 106 and subsystems of the IPTV media system for services such as video-on-demand (VoD), browsing an electronic programming guide (EPG), or other infrastructure services.
Some of the network elements of the IPTV media system can be coupled to one or more computing devices 130 a portion of which can operate as a web server for providing portal services over an Internet Service Provider (ISP) network 132 to wireline media devices 108 or wireless communication devices 116 by way of a wireless access base station 117 operating according to common wireless access protocols such as Wireless Fidelity (WiFi), or cellular communication technologies (such as GSM, CDMA, UMTS, WiMAX, Software Defined Radio or SDR, and so on).
Another distinct portion of the one or more computing devices 130 can be used as a presence system 130 (herein referred to as presence system 130) for collecting presence information associated with users of the first communication system 100. Presence information can indicate for example the whereabouts of users as well as the communication devices in use by these users. The whereabouts of a user can be determined from GPS coordinates transmitted by communication devices of the users to the presence system 130, or from triangulation analysis performed from data provided by base stations such as reference 117. The presence system 130 can determine which communication devices are in use by a particular user by monitoring network activity generated thereby, or from status information provided by the communication devices. The presence system 130 can for example determine from network activity derived from common network elements such as switches or routers that a user is working from a computer terminal at his/her office, using a cellular phone, office phone, home phone, or otherwise. The presence system 130 can make a similar determination by polling communication devices of the user to determine their state of usage.
It will be appreciated by an artisan of ordinary skill in the art that a satellite broadcast television system can be used in place of the IPTV media system. In this embodiment, signals transmitted by a satellite 115 supplying media content can be intercepted by a common satellite dish receiver 131 coupled to the building 102. Modulated signals intercepted by the satellite dish receiver 131 can be submitted to the media processors 106 for generating broadcast channels which can be presented at the media devices 108. The media processors 106 can be equipped with a broadband port to the ISP network 132 to enable infrastructure services such as VoD and EPG described above.
In yet another embodiment, an analog or digital broadcast distribution system such as cable TV system 133 can be used in place of the IPTV media system described above. In this embodiment the cable TV system 133 can provide Internet, telephony, and interactive media services.
It follows from the above illustrations that the present disclosure can apply to any present or future interactive media content services.
FIG. 2 depicts an illustrative embodiment of a communication system 200. employing an IP Multimedia Subsystem (IMS) network architecture to facilitate the combined services of circuit-switched and packet-switched systems. Communication system 200 can be overlaid or operably coupled with communication system 100 as another representative embodiment of communication system 100.
Communication system 200 can comprise a Home Subscriber Server (HSS) 240, a tElephone NUmber Mapping (ENUM) server 230, and other common network elements of an IMS network 250. The IMS network 250 can establish communications between IMS compliant communication devices (CD) 201, 202, Public Switched Telephone Network (PSTN) CDs 203, 205, and combinations thereof by way of a Media Gateway Control Function (MGCF) 220 coupled to a PSTN network 260.
IMS CDs 201, 202 can register with the IMS network 250 by contacting a Proxy Call Session Control Function (P-CSCF) which communicates with a corresponding Serving CSCF (S-CSCF) to register the CDs with at the HSS 240. To initiate a communication session between CDs, an originating IMS CD 201 can submit a Session Initiation Protocol (SIP INVITE) message to an originating P-CSCF 204 which communicates with a corresponding originating S-CSCF 206. The originating S-CSCF 206 can submit queries to the ENUM system 230 to translate an E.164 telephone number in the SIP INVITE to a SIP Uniform Resource Identifier (URI) if the terminating communication device is IMS compliant.
The SIP URI can be used by an Interrogating CSCF (I-CSCF) 207 to submit a query to the HSS 240 to identify a terminating S-CSCF 214 associated with a terminating IMS CD such as reference 202. Once identified, the I-CSCF 207 can submit the SIP INVITE to the terminating S-CSCF 214. The terminating S-CSCF 214 can then identify a terminating P-CSCF 216 associated with the terminating CD 202. The P-CSCF 216 then signals the CD 202 to establish communications.
If the terminating communication device is instead a PSTN CD such as references 203 or 205, the ENUM system 230 can respond with an unsuccessful address resolution which can cause the originating S-CSCF 206 to forward the call to the MGCF 220 via a Breakout Gateway Control Function (BGCF) 219. The MGCF 220 can then initiate the call to the terminating PSTN CD by common means over the PSTN network 260.
The aforementioned communication process is symmetrical. Accordingly, the terms “originating” and “terminating” in FIG. 2 are interchangeable. It is further noted that communication system 200 can be adapted to support video conferencing by way of common protocols such as H.323. In addition, communication system 200 can be adapted to provide the IMS CDs 201, 203 the multimedia and Internet services of communication system 100.
The presence system 130 of FIG. 1 can be operably coupled to the second communication system 200 for purposes similar to those described above.
FIG. 3 depicts an illustrative embodiment of a portal 302 which can operate from the computing devices 130 described earlier of communication 100 illustrated in FIG. 1. The portal 302 can be used for managing services of communication systems 100-200. The portal 302 can be accessed by a Uniform Resource Locator (URL) with a common Internet browser such as Microsoft's Internet ExplorerTM using an Internet-capable communication device such as those described for FIGS. 1-2. The portal 302 can be configured, for example, to access a media processor 106 and services managed thereby such as a Digital Video Recorder (DVR), a VoD catalog, an EPG, a personal catalog (such as personal videos, pictures, audio recordings, etc.) stored in the media processor, provisioning IMS services described earlier, provisioning Internet services, provisioning cellular phone services, and so on.
FIG. 4 depicts an exemplary embodiment of a communication device 400. Communication 400 can serve in whole or in part as an illustrative embodiment of the communication devices of FIGS. 1-2. The communication device 400 can comprise a wireline and/or wireless transceiver 402 (herein transceiver 402), a user interface (UI) 404, a power supply 414, a location receiver 416, and a controller 406 for managing operations thereof. The transceiver 402 can support short-range or long-range wireless access technologies such as Bluetooth, WiFi, Digital Enhanced Cordless Telecommunications (DECT), or cellular communication technologies, just to mention a few. Cellular technologies can include, for example, CDMA-1X, UMTS/HSDPA, GSM/GPRS, TDMA/EDGE, EV/DO, WiMAX, SDR, and next generation cellular wireless communication technologies as they arise. The transceiver 402 can also be adapted to support circuit-switched wireline access technologies (such as PSTN), packet-switched wireline access technologies (such as TCPIP, VoIP, etc.), and combinations thereof.
The UI 404 can include a depressible or touch-sensitive keypad 408 with a navigation mechanism such as a roller ball, joystick, mouse, or navigation disk for manipulating operations of the communication device 400. The keypad 408 can be an integral part of a housing assembly of the communication device 400 or an independent device operably coupled thereto by a tethered wireline interface (such as a USB cable) or a wireless interface supporting for example Bluetooth. The keypad 408 can represent a numeric dialing keypad commonly used by phones, and/or a Qwerty keypad with alphanumeric keys. The UI 404 can further include a display 410 such as monochrome or color LCD (Liquid Crystal Display), OLED (Organic Light Emitting Diode) or other suitable display technology for conveying images to an end user of the communication device 400. In an embodiment where the display 410 is touch-sensitive, a portion or all of the keypad 408 can be presented by way of the display.
The UI 404 can also include an audio system 412 that utilizes common audio technology for conveying low volume audio (such as audio heard only in the proximity of a human ear) and high volume audio (such as speakerphone for hands free operation). The audio system 412 can further include a microphone for receiving audible signals of an end user. The UI 404 can further include an image sensor 413 such as a charged coupled device (CCD) camera for capturing still or moving images.
The power supply 414 can utilize common power management technologies such as replaceable and rechargeable batteries, supply regulation technologies, and charging system technologies for supplying energy to the components of the communication device 400 to facilitate long-range or short-range portable applications. The location receiver 416 can utilize common location technology such as a global positioning system (GPS) receiver for identifying a location of the communication device 100 based on signals generated by a constellation of GPS satellites, thereby facilitating common location services such as navigation. The controller 406 can utilize computing technologies such as a microprocessor, a digital signal processor (DSP), and/or a video processor with associated storage memory such a Flash, ROM, RAM, SRAM, DRAM or other storage technologies.
The communication device 400 can be adapted to perform the functions of the media processor 106, the media devices 108, or the portable communication devices 116 of FIG. 1, as well as the IMS CDs 201-202 and PSTN CDs 203-205 of FIG. 2. It will be appreciated that the communication device 400 can also represent other common devices that can operate in communication systems 100-200 of FIGS. 1-2 such as a gaming console and a media player.
FIG. 5 depicts an illustrative method 500 for managing conference calls. FIG. 6 depicts an illustrative embodiment of a block diagram 600 of communication devices operating according to method 500. Block diagram 600 comprises a communication device 602 in the form of a tablet with a touch-sensitive display (herein referred to as tablet 602). The tablet 602 can include communication technology to support both DECT and WiFi protocols. The tablet 602 can be communicatively coupled to a base unit 606 by way of the DECT and WiFi air interfaces. A plurality of cordless handsets 604 can also be communicatively coupled to the base unit 606 using the DECT protocol.
The base unit 606 can include communication technology for communicatively interfacing to a PSTN, VoIP or IMS network such as those described earlier. The base unit 606 can also include communication technology for communicatively interfacing to the ISP network 132 of FIG. 1 by way of a common Internet/router modem 608. The base unit 606 can provide the cordless handsets voice communication services, and the tablet 602 a combination of voice and data communication services. The tablet 602 and cordless handsets 604 can be equipped with common camera sensors 610 (such as charged coupled device sensors) which can enable these devices to support video communication services.
With the configuration of FIG. 6 in mind, method 500 can begin with step 502 in which a user of one of the communication devices of FIG. 6 selects a plurality of parties from a communication log to engage in a conference call with the parties as participants. The communication device referred to in this instance can be one of the cordless handsets 604 or the tablet 602. The communication log can represent either a dialed calls log, received calls log, or a combination thereof. The user can highlight by means of a user interface (UI) of the communication device entries in a received or dialed call entry.
The UI of the communication device can for example support a mouse pointer function which allows the user to select more than one entry in a log. The user can signal the communication device, for example, that more than one entry is to be selected by depressing a control button on a Qwerty keyboard presented by the display of the tablet 602 while selecting multiple participants. Alternatively, the UI can present the user in the communication log a button (e.g., such as “Multi-party”) which when selected signals the communication device that multiple selections will follow. Thus each selection the user makes, highlights an entry in the call log. If the user selects a highlighted entry again, the selection can be de-highlighted, thereby making the selection process a toggle function.
The user can highlight more than one entry in either log, and then initiate a request for a multi-party call by selecting a send button on the phone as one would commonly do in a single number dialing process. Highlighting more than one entry in the logs can indicate to the communication device (602 or 604) that the actions taken represent a conference call.
In another embodiment, the user can direct the communication device in step 504 to record a calendar notice for a conference call with a plurality of attendees (or participants). The calendar notice can be accepted by the participants which can also be recorded by the communication device. When the communication device detects a trigger of the calendar event in step 506, the communication device can once again detect a multi-party conference call based on the listed participants in the calendar notice.
Upon detecting a multi-party call in step 502 originating from the communication logs, or the calendar event in step 506 also initiating a conference call with multiple parties, the communication device can proceed to step 508 as an intermediary step before initiating a conference call. In step 508, the communication device can retrieve from the presence system 130 presence information for each participant. In the case of the table 602 this step can represent a communication exchange with the presence system 130 over the data connection provided by the base unit 606 over the WiFi air interface. The presence information can indicate to the communication device the availability of each participant to accept a call, and which communication device of the targeted participant can be used to reach said participant.
With this information, the communication device can proceed to step 510 to retrieve from an address book a communication identifier and a conferencing type of each communication device identified for the participants in step 508. The address book of the communication device can for example store information about multiple communication devices of each participant (cell phone, house phone, office phone, soft phone, etc.). For each participant, the address book can also have a conferencing type entry for each communication device of the participant. For communication devices of the participants which can only support voice communications, the conferencing type associated with these devices can designate a voice-only device. For communication devices that can support video communications, the conferencing type can designate a capability for video communications.
Since it is possible that not all participants will have video conferencing capability, the communication device can be programmed in step 512 to present the user a list of the participants and the respective capabilities of their communication devices. A sample of this list is shown in FIG. 6 as reference 612. The user can review this list before initiating the call to determine how best to engage with the participants. In one embodiment, for example, the user can select a GUI button shown under the table to engage in video-only communications with participants having this capability (e.g., participants 1 and N). When this selection is made, the communication device can proceed to steps 516 where it identifies the participants capable of video communications (1 and N) and initiates a video-only conference with these participants in step 518. The video-only conference can take place over the communication network of FIG. 2 using a common video conferencing protocol such as H.323.
In another embodiment, the user can request a voice-only communication session. In this instance, the conference all can occur in step 520 with all participants 1 through N, since all parties have communication devices that support voice services. The IMS network 250 of FIG. 2 can support participants with PSTN communication devices and others with VoIP communication devices.
In yet another embodiment, the user can choose a hybrid communication session in which some participants are contacted on a video channel, while others are contacted on a voice-only channel. The IMS network 250 can perform the necessary multiplexing tasks so that the communication device can initiate in step 522 a communication session with some participants engaged by voice and video, while others are engaged by voice only.
Upon reviewing the aforementioned embodiments, it would be evident to an artisan with ordinary skill in the art that said embodiments can be modified, reduced, or enhanced without departing from the scope and spirit of the claims described below. Method 500 can be adapted so that a presence system 130 is not utilized. In this embodiment, participants can be called and only those who answer the call are joined to a voice-only, video-only, or hybrid communication session.
Other suitable modifications can be applied to the present disclosure without departing from the scope of the claims below. Accordingly, the reader is directed to the claims section for a fuller understanding of the breadth and scope of the present disclosure.
