## Background
FIELD OF THE DISCLOSURE
The subject disclosure relates to an apparatus and method for accessing a back-end service, and more particularly to a backend-as-a-service, software defined network element.
BACKGROUND
Mobile devices which require access to enterprise backend data sources generally rely on middleware servers, such as Mobile Enterprise Applications Platforms (MEAP) or Mobile Applications Development Platforms (MADP) to provide this information. For example, a mobile application can be written to request financial transactions from an Oracle Financial database residing in an enterprise datacenter. In this example, the mobile device application issues data requests to a Mobile Enterprise Applications Platform (MEAP) or Mobile Applications Development Platform (MADP) middleware gateway and/or server residing in the enterprise data center, which subsequently accesses backend data sources, e.g., databases, and forwards this data to the mobile application.
In other words, when an application residing on a mobile device requires access to a database, e.g., an Oracle database residing in the enterprise data center, the mobile application interfaces with a middleware server. These servers are known by various acronyms, such as, Mobile Enterprise Applications Platforms (MEAP) or Mobile Applications Development Platforms (MADP).
MEAP and/or MADP gateways can be resident at datacenters of the enterprise organizations and generally receive data from a mobile device by way of the mobile network. In an LTE environment, the MEAP/MADP gateways receive the data from an LTE gateway. The MEAP/MADP gateway residing in the enterprise premises accesses backend data sources, such as Oracle databases, and forward the information requested back to the LTE gateway for delivery to the mobile device. Thus, the LTE gateway residing in the carrier network essentially passes data back and forth between the mobile device and the MEAP/MADP servers.

DETAILED DESCRIPTION
The subject disclosure describes, among other things, illustrative embodiments of software defined network element front-ending a gateway of the core network provides mobile devices with an ability to access back-end data sources residing in the cloud and in enterprise customer data centers. Mobile clients accesses services provided by a software-defined network, mobile backend-as-a-service network element that subsequently interfaces with a corresponding software-defined network, mobile backend-as-a-service element residing in the cloud or enterprise customer data center containing backend services. Other embodiments are described in the subject disclosure.
The carrier is disintermediated from this process—it is just passing data back and forth from and to the mobile device. One or more aspects of the subject disclosure include software-defined network, mobile backend-as-a-service network element that allow mobile devices to dynamically access back-end data sources (such as Oracle and SAP databases) residing in the cloud or enterprise customer data centers without mobile middleware servers. In some instances, mobile devices can access the back-end data sources without requiring a resident back-end client, or even a related application. Namely, requests for back-end services can be made through existing messaging infrastructures, such as short message service (SMS) or Mobile Multimedia Messages (MMS) according to the techniques disclosed herein.
One embodiment of the subject disclosure includes a device including a processor and a memory that stores executable instructions. The executable instructions, when executed by the processor, facilitate performance of operations that include creating a first software defined network element in local communication with a gateway of an evolved packet core of a long-term evolution network. Establishment of a first logical network connection is facilitated between the first software defined network element and a second software defined network element in local communication with a remotely accessible system. A request initiated by a mobile device serviced by the long-term evolution network is received for access to a service of the remotely accessible system. The request is translated and forwarding to the second software defined network element by way of the first logical network connection. The second software defined network element forwards the translated request to the remotely accessible system.
Another embodiment of the subject disclosure includes a machine-readable storage medium, including executable instructions that, when executed by a processor, facilitate performance of operations. The operations including creating a first software defined network element in local communication with equipment of a core network of a mobility network. Establishment of a first logical network connection is facilitated between the first software defined network element and a second software defined network element in local communication with a remotely accessible system. A first message is received including a request initiated by a mobile device serviced by the mobility network for access to a service of the remotely accessible system. A second message is forwarded including the request to the second software defined network element by way of the first logical network connection. The second software defined network element forwards the second message to the remotely accessible system by way of an application programming interface.
Yet another embodiment of the subject disclosure includes a process, including creating, by a system including a processor, a number of software defined network elements at a network carrier premises. Establishment of number of logical network connection are facilitated by the system between the number of software defined network elements and a number of network elements in local communication with a number of back-end servers at enterprise premises. A request initiated by a mobile device is received by the system for access to a service of a particular back-end server of the number of back end servers. A location is identified of the particular back-end server of the number of back-end servers, and forwarded by the system to the network element. The message is forwarded by way of a logical network connection of the number of logical network connections corresponding to the location of the particular back-end server. The network element forwards the request to the particular back-end server of the number of back-end servers.
FIG. 1 depicts an illustrative embodiment of a communication system 100 that provides a backend-as-a-service, software defined network element. The system 100 supports mobile access to remote, back-end services hosted by data centers 102a, 102b (generally 102). A mobile device 104 accesses the back-end services by way of a network infrastructure. In the illustrative example, the network infrastructure includes a carrier network 106 in communication with the data centers 102 by way of an internet protocol (IP) network 108. The mobile device 104 accesses the carrier network 106 by way of a radio terminal, such as an enhanced Node B (eNB) 110.
The carrier network 106 includes a core network, such as an Enhanced Packet Core (EPC) 112 of a 4G or Long-Term Evolution (LTE) network. The EPC or core network 112 includes one or more network elements. For LTE networks, the core network 112 generally includes a Serving Gateway (S-GW) 114, a Mobility Management Entity (MME) 116, a Home Subscriber Server (HSS) 118 and a Packet Data Network (PDN) Gateway (P-GW) 120 as shown. The core network gateways 114, 116, 118 and 120 are in communication with each according to pre-defined interfaces S11, S6a, S5/S8a, as shown.
The eNB 110 is in communication with the MME 116 through an S1-MME interface and the S-GW 114 through an S1-U interface. Generally, the MME handles control plane activity, whereas the S-GW handles data or user plane activity. Information packets are routed between the P-GW 120 and one or more other networks, such as the IP network 108, an ISM network and/or GSM network (not shown).
In some embodiments, the carrier network 106 includes a Software Defined Network (SDN) controller or master 122. The SDN controller 112 is in communication with other SDN network elements, referred to as Mobile Back-End as a Service (MBAS) SDN network elements 124a, 124b (generally 124). It is envisioned that an SDN master controller 122 implemented in the carrier premises 106 manages relationships between the MBAS SDN element 124 and various MBAS SDN-e elements 140 residing in enterprise customer premises 102. The MBAS SDN elements 124 allow for implementation of a software implementation of network elements that can be created either as a pre-defined software resource or created dynamically in response to changing network conditions. The MBAS SDN elements 124 can serve as a front end to the core network devices, such as the LTE gateways. In some embodiments, the MBAS SDN element 124 works in conjunction with a software client residing in mobile devices 104. The purpose of the mobile client would be to interface with the MBAS SDN element 124 and issue requests for backend data services. In at least some embodiments, the MBAS SDN element 124 operates transparently to other carrier network elements as part of the LTE gateway 120. The MBAS SDN element 124 can work in close linkage with a corresponding MBAS SDN network element or gateway 230 residing in the enterprise network or the cloud service provider 202.
The SDN controller 122 can be a stand-alone processor, such as a server, an element of a blade processor, or a portion of an existing processor. The MBAS SDN network elements 124 can be hosted on the same processing platform as the SDN controller 122, and/or on another processing platform. One or more of the MBAS SDN network elements 124 and/or the SDN controller can be in communication with storage 126 and/or a knowledge engine 128. The knowledge engine can be implemented as an Artificial Intelligence (AI) engine 128. The AI engine 128 includes or otherwise has access to a memory cache 129.
The AI engine 128 supports the MBAS SDN element 124 and provides an ability to learn and anticipate data requests. In some embodiments, previously processed requests can be cached and used in subsequent queries in a predictive manner. For example, if a mobile user requests services, such as reports according to a particular schedule, the AI engine 128 can determine particulars related to the report and/or the schedule. The AI engine 128, in cooperation with the MBAS SDN element 124 can issue a request in anticipation of a request not yet received from the mobile user. Replies or reports resulting from such anticipatory requests can be sent, e.g., pushed to the mobile device in an unsolicited manner. Alternatively or in addition, the unsolicited results/reports can be stored, e.g., at the storage 126 and a notification sent to the mobile device. The notification can be any suitable mode, including an SMS message, an MMS message with a link to the stored results/reports, an email message, a phone call, e.g., with a pre-recorded voice message, or voice message synthesize from text to information the user of the mobile device 104 that the results are available.
The data centers 102 can belong to an enterprise organization, such as a business or other institution. Alternatively or in addition the data centers 102 can belong to a third party, such as a cloud service provider, e.g., Google®. Each of the data centers 102 can include a server 130a, 130b (generally 130), referred to as a back-end or cloud server, and storage 132a, 132b (generally 132) accessible to the server(s) 130. The server(s) 130 can host one or more services under what is generally understood as a service-oriented architecture, e.g., the SAP Enterprise Service Oriented Architecture. The services can be offered to members, e.g., employees, of a particular enterprise, to clients or customers, to vendors or suppliers, to business partners or collaborators, and so forth. The services can be accessed in machine-to-machine transactions from within the premises of the enterprise and/or remotely at an associated network address and by way of network connectivity to the remote machine.
In the illustrative example, the mobile device 104 includes an application program or “app” 134 that may be accessed or otherwise launched by way of an icon 136 displayable on a user interface of the mobile device 104. In this example, the mobile app 134 accesses back-end services available from the back-end servers. In some embodiments, the mobile device 104 includes a resident back-end client 138 to access services offered by the back-end server(s) 130. Examples of services include business applications related to one or more of accounting, distribution, production, procurement, sales, customer service, corporate performance and governance, human resource and so on.
Consider a corporate performance application 134 requiring access to financial reports of the corporation. The application 134 can call on the back-end client 138 to initiate a machine-machine communication between the mobile device 104 and the back-end server 130a at the enterprise data center 102a. The back-end client 138 can generate a request for information and send the request to the back-end server 130a. The back-end server 130a, responsive to receiving the request, can access stored financial data from the storage 132a. In some embodiments, a middleware server can be used to translate or otherwise modify the request to a format appropriate for the back-end server 130a. The back-end server 130a, in turn, can produce and in at least some instances format the requested information in a report, as may be appropriate, e.g., for the particular application 134.
In the previous example, communications between the mobile device and the back-end server rely on a client-server model that can include a middleware server, as may be required. Particulars of the request and the returned information or reports can be managed by the client-server arrangement. Namely, knowledge of particular request, formats and so on are generally identified beforehand. The back-end client 138 can prepare requests and replies according to requirements of one or more of the application 134, the middleware servers (when provided), and the back-end server 130a. In such instances, the carrier network 106, an particularly the core network 112 largely relay messages between the mobile device 104 and the enterprise data center 102a. It is conceivable that for a large, e.g., national carrier, the number of enterprise data centers can be in the hundreds or greater. Consider at least 500 such data centers 102, one enterprise data center 102 for each of the Fortune 500 companies.
Beneficially, the MBAS SDN element(s) 124 are resident at the carrier network premises and therefore closely and reliably accessible to elements of the carrier network, such as the gateways of the core network 112. Accordingly, communications between the MBAS SDN elements 124 and the locally accessible gateways of the core network 112 can be reliably and securely accomplished by low level interfaces. For example, the interfaces can be accomplished by one or more of layers 1-4 of the OSI model, without requiring layers 5-7. Alternatively, or in addition, the MBAS SDN elements 124 and the locally accessible gateways of the core network 112 can communicate over other low-level interfaces including proprietary interfaces that may include limited or no error detection and/or error correction. The interfaces may include limited or no security, as such security would not be necessary considering the MBAS SDN elements 124 are under the direct control of the carrier, e.g., located on secure carrier premises. Such low-level interfaces can simplify protocol stacks and associated network communications.
In the illustrative embodiment, the MBAS SDN element(s) 124 can initiate a logical network path to equipment at the enterprise data center(s) 102, such as the back-end server(s) 130. Such logical network paths can be pre-configured, e.g., during provisioning. Alternatively or in addition, the logical network paths can be added, deleted and/or reconfigured on-the-fly. Such an adaptive nature of the logical network allows the carrier network to adjust the logical network paths as may be necessary to respond to changing network conditions. Further, by using logical network elements 124, the provisioning of network paths can be accomplished without regard to the underlying physical network connections. This allows the carrier to adjust the network in an ad hoc or reactive manner.
In some embodiments, the mobile device is not equipped with nor does it require the back-end client 138. Rather, the MBAS SDN element(s) 124 at the core network 112 is configured to receive request directly from the application 134. These can include requests directed from the application 134 and/or from a user of the mobile device 104 by any suitable means, such as text messages through SMS or text/multimedia messages through MMS. The MBAS SDN element(s) 124 can receive supplemental information from the message itself and/or from the carrier.
The supplemental information an include one or more of identities of the mobile device 104, a user of the mobile device 104, the application 134, the enterprise data center 102, the back-end server 130, a service requested from the back-end server 130, and so on. The supplemental information can be obtained from the message, e.g., in a header portion. Alternatively or in addition, all or a portion of the supplemental information can be provided by the carrier. Such carrier-provided information can include network information, such as one or more of statistics, capacity, billing, as a real time value based on current conditions. It is also envisioned that the network information can include historical information, e.g., past usage, and/or predictive information, such as expected outages, limitations to bandwidths, changes in billing rates, and so on.
The MBAS SDN network element(s) 124 can exchange messages between itself and the back end server(s) 130 without modification. Alternatively or in addition, the MBAS SDN network element(s) 124 can intercept such messages, translate and/or reformat, as may be required. Thus, an application might use a particular set of commands that are not recognizable or otherwise serviceable directly by the back-end server.
An example includes an SMS message typed by a user: “provide second quarter financials.” This SMS message could be relayed directly to the MBAS SDN via another network entity, such as Short Message Peer-to-Peer (SMPP) gateway. The MBAS SDN 124a might receive this message directly, e.g., by a user sending it via SMS addressed to a short code identifying one of the SDN controller 122 and/or the MBAS SDN 124a. It is envisioned that the MBAS SDN element 124 is supported by a large set of catalogs and databases, which would contain records, such as records of mobile clients, requests, associated databases and location of MBAS SDN-e elements 140. For example, the MBAS SDN element 124 can be supported by a security catalog, which would enable the MBAS SDN element 124 to restrict usage and assign privileges to individual requests based on pre-provisioned parameters. The MBAS SDN 124a has access to stored information 126 and/or the AI engine 128. The MBAS SDN 124a can be programmed to directly translate message, for example, according to a look up table as might be stored in the local storage 126. Alternatively, some degree of interpretation may be necessary. An interpretive feature is advantageous, particularly for such free-form messages as those provided by email, SMS, MMS and so on.
According to generally well understood techniques, such free form messages can be parsed according to one or more of a grammar and a dictionary. The parsed message in whole or in part can be interpreted and translated or otherwise used to generate another message. The other message is destined for the target back-end server 130a and subscribes to grammars, semantics, and/or syntax as may be required by applications serviced by the back-end server 130a. Certain words, e.g., those related to a particular application, such as finance, governance, human resources can be used to identify one or more of the particular back-end server 130a or back-end service of multiple services hosted by the server 130a to receive the message. Such partial identifications can be used to facilitate interpretation.
For example, having determined that the message relates to financial services can reduce the set of possible messages available by a financial back-end service. Other message content, such as date(s), amount(s), entities, formats, and so on can be interpreted. The MBAS SDN 124a and/or the SDN controller 122 can translate the message, e.g., the SMS text message, to a translate message suitable for the intended back end service. Other information, such as an identity of the mobile user and/or mobile device can be used to identify the particular enterprise data center 102a and/or the particular back-end server 130a or back-end service sought.
In some embodiments, one or more of the enterprise data centers 102 include a software defined network element 140a, 140b (generally 140). In particular the software defined network element is in communication with the mobile back-end server 130a and referred to as a Mobile Back-End as a Service, Software Defined Network enterprise (MBAS SDN-e) element 140. The MBAS SDN-e element 140 can be hosted on a dedicated processor, such as a server or gateway at the enterprise data center 102. Alternatively, the MBAS-SDN element 140 can be hosted on an existing processor, e.g., supporting other activities at the enterprise data center 102. It is envisioned that the MBAS-SDN element 140 can include one or more Application Programming Interfaces (APIs) 142a, 142b (generally 142) as may be necessary to support interaction with those back-end services made available to the mobile user. The MBAS SDN-e elements 140 can receive requests from the carrier MBAS SDN element 124 and interface via API's 142 with the backend data sources 130 such as Oracle databases. An MBAS SDN-e element 140 residing in the enterprise network or cloud services provider 102 can be implemented as a standalone gateway or as part of a router or additional gateways. It is also envisioned that the MBAS SDN-e element 140 residing in the enterprise network 102 can be implemented as part of a MADP/MEAP gateway as software defined network element. When present, the MBAS-SDN-e element 140 at the enterprise data center 102 communicates with the MBAS SDN element 124 at the core network 112 by way of the logical network connection established between the two devices 140, 124.
FIG. 2 another illustrative embodiment of a communication system 200 that provides a backend-as-a-service, software defined network element. The system 200 supports mobile access to remote, back-end services hosted by one or more data centers 202. A first mobile device 204a accesses the back-end services by way of a network infrastructure. In the illustrative example, the network infrastructure includes a carrier network 206 in communication with the data center 202 by way of an internet protocol (IP) network 208. The first mobile device 204a accesses the carrier network 206 by way of a radio terminal, such as an enhanced Node B (eNB) 210.
The carrier network 206 includes a core network 212, e.g., of an LTE network. The core network 212 includes one or more network elements, such as an S-GW 214, an MME 216, an HSS 218 and a P-GW 220 as shown. The eNB 210 is in communication with the MME 116, which generally handles control plane activity and the S-GW 224 in further communication with the P-GW 220, which generally handle user or data plan activity. Information packets are routed between the P-GW 220 and one or more other networks, such as the IP network 208, an IMS network 254 and/or GSM network 252. In the illustrative example, a second mobile device 204b communicates with the GSM network 252 by way of a base transceiver station 250. One or more of the GSM network 252 and the IMS network 254 can be in communication with the carrier network 206 by a direct connection, e.g., by way of the P-GW 220, or indirectly, by way of another network, such as the IP network 208.
Also shown are an SMS gateway 256 and an MMS gateway 258 for passing SMS and/or MMS network messages according to generally well understood techniques. Since the MBAS SDN element 224 resides in the carrier network 206, it is envisioned that the MBAS SDN element 224 can interface with other carrier network elements such as the SMS gateway 256 and MMS gateway 258. The MBAS SDN element 224 can have the ability to integrate mobile device requests with other sources of data such as the SMS and MMS gateways 256, 258. One of the SMS gateway 256, the MMS gateway or both can be in communication with the carrier network 206, and particularly with an MBAS SDN element 225 operated by the carrier network 206. Such network paths between the MBAS SDN element 225 and the mobile devices 204a, 204b (generally 204) allows SMS and/or MMS message to be directed from the mobile device(s) 204 directly to the MBAS SDN element 224. Once again, this can be accomplished by a destination address, such as a short code, a telephone number, or an internet address.
The SMS and/or MMS messages, once received by the MBAS SDN element 224 can be processed as described above. That is, the messages can be translated, as required, with the translated message being directed from the MBAS SDN element 224 to a back-end server 230 by way of a middleware server, or without such a middleware server. The ability to service data requests issued by mobile devices 204 without the need of a middleware gateway and/or without the need of a mobile client. In some embodiments, the enterprise data center includes an MBAS SDN-e element 240 in network communication with the MBAS SDN element 224 of the carrier by way of a logically defined network. The logically defined nature, along with application of generally well-understood software defined network techniques allows all of the advantages and flexibility disclosed above in reference to FIG. 1.
Messages received from the mobile device(s) 204 at the MBAS SDN 224 result in one or more reply message(s) directed from the back-end server, e.g., by way of the MBAS SDN-e element 240, to the MBAS SDN 224 by way of the logical network. The MBAS SDN 224 can forward the reply message(s) to the corresponding mobile device(s) 204. In some embodiments, messages sent by the mobile device 204 by way of SMS and/or MMS messaging services generate reply messages in a like manner. Namely, an SMS request message can result in an SMS reply message. Likewise, an MMS request can result in an MMS reply. However, in some instances, a simple request message can result in a requested service that requires features not available to the source messaging service.
Consider an SMS message request for a financial report. The request might be a simple text phrase, e.g., “get 2013 financial report.” The result however, might be inappropriate for SMS for any of various reasons. The result may be lengthy and exceed message lengths. The results might contain special formatting and/or graphics that are not well suited to the messaging service used in the request. In such instances, one of the MBAS SDN-e element 242, the MBAS SDN 224 element 224, the SDN controller 222 or another processor, such as the AI engine 128 (FIG. 1) can compare the requesting message service or format and identify a suitable reply service or format. In the simple SMS request resulting in a length, complex result with special formatting and graphics, the MBAS SDN-e element 242, the MBAS SDN 224 element 224, the SDN controller 222 or another processor can determine that am MMS reply would be sufficient. That is, a relatively short message indicating that a reply is present, along with a pointer, such as an HTTP or web address to the resulting report. The web report can be sent from the back-end server 230 to a web server, e.g., in a DMZ 260 of the enterprise data center or some other location, such as an Internet and/or cloud service provider. Selection of the link provided in the SMS reply message will direct the mobile device 204 to the appropriate HTTP document or web page to view results.
Alternatively or in addition, results can be provided by other modes, such as by an email. The email address of the recipient, e.g., a user of the mobile device 204, can be provided according to records of the enterprise organization, the carrier, or within the message itself, e.g., during a translation. If it is recognized during a translation that the originating message format or service would be insufficient or otherwise inadequate for a reply, the MBAS SDN 224 can include such information within the translated message. That is, the translated message might simply identify a mode for providing the requested service according to a user preference, an enterprise preference, best practices, and so on. In this instance, the MBAS SDN-e element 240 receives the translated reply and notification as to which mode should be used in providing the requested service.
FIG. 3 depicts an illustrative embodiment of a process 300 used in portions of the system described in FIGS. 1-2 and 4-5. A software-defined network element is created at a carrier network facility at 302. For example, the MBAS SDN element 124a can be created on a processor at carrier network premises housing the core network 112. A logical network connection between the software-defined network element at the carrier network facility and a network entity in local communication with a remotely accessible system at 304. The logical network connection can be established between the MBAS SDN 124a at the carrier network premises and the MBAS SDN-e element 140a at the enterprise organization premises, such as the enterprise data center 102a. The logical network can be established using generally well understood techniques related to software defined networks. In other embodiments, the logical network can be established between the MBAS SDN element 124a and a middle ware server, a dedicated network element, such as a router, a switch or a gateway in network communications with the back-end server 130a. 
A request is received at the software-defined network element of the carrier network facility at 306. For example, a request from the mobile device 104 in the form of a request message is directed to a network address of the MBAS SDN element 124a. By its close association and colocation with the core network 112, the message received by way of the core network 112 can be directed to the MBAS SDN element 124a by way of a low-level interface. That is, a low-level interface of one of the core network gateways, such as the P-GW 120. The low-level interface alone or in combination with a close network association provided by the network communications established between the MBAS-SDN element 124a and the MBAS SDN-e element 140a generally result in efficient, reliable and secure delivery of back-end enterprise services to mobile users.
In some embodiments, a determination is made at 308, whether the received request requires translation at 308. In some instances, the mobile application 134 provides the request message in a suitable format, e.g., with proper grammar, syntax and so forth. For example, translations may not be required if the mobile device 104 includes a back-end client 138 that is pre-configured to issue request for back-end services in a suitable formats. In such instances, a translation would not generally be required. In other instances, e.g., when the mobile device is not configured with the back-end client 128, at least some degree of translation may be required. One of the SDN controller 122, the MBAS SDN 124a or both can be configured to determine whether a translation is required. Such determinations can be made according to one of a message header, a message syntax, a message grammar or lack thereof, and so forth. To the extent that translation is required, the translation is performed at 310.

FIG. 4 depicts an illustrative embodiment of a first communication system 400 for delivering media content. The communication system 400 can represent an Internet Protocol Television (IPTV) media system. Communication system 400 can be overlaid or operably coupled with the communication systems 100, 200 of FIGS. 1 and/or 2 as another representative embodiment of communication system 400. For instance, one or more devices illustrated in the communication system 400 of FIG. 4 can create a software defined network element in local communication with a gateway of a service-provider network. Establishment of a first logical network connection can be facilitated between the first software defined network element and another network element in local communication with a remotely accessible back-end system. A request from a communication device for access to a service of the remotely accessible system is received and forwarded to the other network element by way of the first logical network connection. The other network element forwards the translated request to the back-end system.
The IPTV media system can include a super head-end office (SHO) 410 with at least one super headend office server (SHS) 411 which receives media content from satellite and/or terrestrial communication systems. In the present context, media content can represent, for example, audio content, moving image content such as 2D or 3D videos, video games, virtual reality content, still image content, and combinations thereof. The SHS server 411 can forward packets associated with the media content to one or more video head-end servers (VHS) 414 via a network of video head-end offices (VHO) 412 according to a multicast communication protocol.
The VHS 414 can distribute multimedia broadcast content via an access network 418 to commercial and/or residential buildings 402 housing a gateway 404 (such as a residential or commercial gateway). The access network 418 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 fiber optical links or copper twisted pairs 419 to buildings 402. The gateway 404 can use communication technology to distribute broadcast signals to media processors 406 such as Set-Top Boxes (STBs) which in turn present broadcast channels to media devices 408 such as computers or television sets managed in some instances by a media controller 407 (such as an infrared or RF remote controller).
The gateway 404, the media processors 406, and media devices 408 can utilize tethered communication technologies (such as coaxial, powerline or phone line wiring) or can operate over a wireless access protocol such as Wireless Fidelity (WiFi), Bluetooth®, Zigbee®, or other present or next generation local or personal area wireless network technologies. By way of these interfaces, unicast communications can also be invoked between the media processors 406 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.
A satellite broadcast television system 429 can be used in the media system of FIG. 4. The satellite broadcast television system can be overlaid, operably coupled with, or replace the IPTV system as another representative embodiment of communication system 400. In this embodiment, signals transmitted by a satellite 415 that include media content can be received by a satellite dish receiver 431 coupled to the building 402. Modulated signals received by the satellite dish receiver 431 can be transferred to the media processors 406 for demodulating, decoding, encoding, and/or distributing broadcast channels to the media devices 408. The media processors 406 can be equipped with a broadband port to an Internet Service Provider (ISP) network 432 to enable interactive services such as VoD and EPG as described above.
In yet another embodiment, an analog or digital cable broadcast distribution system such as cable TV system 433 can be overlaid, operably coupled with, or replace the IPTV system and/or the satellite TV system as another representative embodiment of communication system 400. In this embodiment, the cable TV system 433 can also provide Internet, telephony, and interactive media services.
The subject disclosure can apply to other present or next generation over-the-air and/or landline media content services system.
Some of the network elements of the IPTV media system can be coupled to one or more computing devices 430, a portion of which can operate as a web server for providing web portal services over the ISP network 432 to wireline media devices 408 or wireless communication devices 416.
Communication system 400 can also provide for all or a portion of the computing devices 430 to function as a software-defined network server (herein referred to as SDN server 430). The SDN server 430 can use computing and communication technology to perform function 462, which can include among other things, techniques described by method 300 of FIG. 3. That is, the SDN server 430 can host the MBAS SDN 124, 224 of the carrier network. For instance, function 462 of server 430 can be similar to the functions described for one or more of the MBAS SDN element 124, 224 or the SDN controller 122, 222 of FIGS. 1 and 2 in accordance with method 300. The media processors 406 and wireless communication devices 416 can be provisioned with software functions 464 and 466, respectively, to utilize the services of software-defined network server 430. For instance, functions 464 and 466 of media processors 406 and wireless communication devices 416 can be similar to the functions described for the communication devices 104, 204 of FIGS. 1 and 2 in accordance with method 300.
In some embodiments, the SDN server 430 can host the MBAS SDN-e element 140, 240 of the enterprise data center 102, 202. In such instances, establishment of a logical network connection can be facilitated between the MBAS SDN element 424 (shown in phantom) of the mobility network 417 servicing mobile devices 416.
Multiple forms of media services can be offered to media devices over landline technologies such as those described above. Additionally, media services can be offered to media devices by way of a wireless access base station 417 operating according to common wireless access protocols such as Global System for Mobile or GSM, Code Division Multiple Access or CDMA, Time Division Multiple Access or TDMA, Universal Mobile Telecommunications or UMTS, World interoperability for Microwave or WiMAX, Software Defined Radio or SDR, Long Term Evolution or LTE, and so on. Other present and next generation wide area wireless access network technologies can be used in one or more embodiments of the subject disclosure.
FIG. 5 depicts an illustrative embodiment of a communication system 500 employing an IP Multimedia Subsystem (IMS) network architecture to facilitate the combined services of circuit-switched and packet-switched systems. Communication system 500 can be overlaid or operably coupled with systems 100, 200 of FIGS. 1 and/or 2 and communication system 400 as another representative embodiment of communication system 400. A software defined network element can be generated in local communication with a gateway of a carrier network. Establishment of first logical network connection can be facilitated between the first software defined network element and another network element in local communication with a remotely accessible back-end system. A request from a communication device for access to a service of the remotely accessible system is received and forwarded to the other network element by way of the first logical network connection. The other network element forwards the translated request to the back-end system.
Communication system 500 can comprise a Home Subscriber Server (HSS) 540, a tElephone NUmber Mapping (ENUM) server 530, and other network elements of an IMS network 550. The IMS network 550 can establish communications between IMS-compliant communication devices (CDs) 501, 502, Public Switched Telephone Network (PSTN) CDs 503, 505, and combinations thereof by way of a Media Gateway Control Function (MGCF) 520 coupled to a PSTN network 560. The MGCF 520 need not be used when a communication session involves IMS CD to IMS CD communications. A communication session involving at least one PSTN CD may utilize the MGCF 520.
IMS CDs 501, 502 can register with the IMS network 550 by contacting a Proxy Call Session Control Function (P-CSCF) which communicates with an interrogating CSCF (I-CSCF), which in turn, communicates with a Serving CSCF (S-CSCF) to register the CDs with the HSS 540. To initiate a communication session between CDs, an originating IMS CD 501 can submit a Session Initiation Protocol (SIP INVITE) message to an originating P-CSCF 504 which communicates with a corresponding originating S-CSCF 506. The originating S-CSCF 506 can submit the SIP INVITE message to one or more application servers (ASs) 517 that can provide a variety of services to IMS subscribers.
For example, the application servers 517 can be used to perform originating call feature treatment functions on the calling party number received by the originating S-CSCF 506 in the SIP INVITE message. Originating treatment functions can include determining whether the calling party number has international calling services, call ID blocking, calling name blocking, 7-digit dialing, and/or is requesting special telephony features (e.g., *72 forward calls, *73 cancel call forwarding, *67 for caller ID blocking, and so on). Based on initial filter criteria (iFCs) in a subscriber profile associated with a CD, one or more application servers may be invoked to provide various call originating feature services.
Additionally, the originating S-CSCF 506 can submit queries to the ENUM system 530 to translate an E.164 telephone number in the SIP INVITE message 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) 507 to submit a query to the HSS 540 to identify a terminating S-CSCF 514 associated with a terminating IMS CD such as reference 502. Once identified, the I-CSCF 507 can submit the SIP INVITE message to the terminating S-CSCF 514. The terminating S-CSCF 514 can then identify a terminating P-CSCF 516 associated with the terminating CD 502. The P-CSCF 516 may then signal the CD 502 to establish Voice over Internet Protocol (VoIP) communication services, thereby enabling the calling and called parties to engage in voice and/or data communications. Based on the iFCs in the subscriber profile, one or more application servers may be invoked to provide various call terminating feature services, such as call forwarding, do not disturb, music tones, simultaneous ringing, sequential ringing, etc.
In some instances the aforementioned communication process is symmetrical. Accordingly, the terms “originating” and “terminating” in FIG. 5 may be interchangeable. It is further noted that communication system 500 can be adapted to support video conferencing. In addition, communication system 500 can be adapted to provide the IMS CDs 501, 502 with the multimedia and Internet services of communication system 400 of FIG. 4.
If the terminating communication device is instead a PSTN CD such as CD 503 or CD 505 (in instances where the cellular phone only supports circuit-switched voice communications), the ENUM system 530 can respond with an unsuccessful address resolution which can cause the originating S-CSCF 506 to forward the call to the MGCF 520 via a Breakout Gateway Control Function (BGCF) 519. The MGCF 520 can then initiate the call to the terminating PSTN CD over the PSTN network 560 to enable the calling and called parties to engage in voice and/or data communications.
It is further appreciated that the CDs of FIG. 5 can operate as wireline or wireless devices. For example, the CDs of FIG. 5 can be communicatively coupled to a cellular base station 521, a femtocell, a WiFi router, a Digital Enhanced Cordless Telecommunications (DECT) base unit, or another suitable wireless access unit to establish communications with the IMS network 550 of FIG. 5. The cellular access base station 521 can operate according to common wireless access protocols such as GSM, CDMA, TDMA, UMTS, WiMax, SDR, LTE, and so on. Other present and next generation wireless network technologies can be used by one or more embodiments of the subject disclosure. Accordingly, multiple wireline and wireless communication technologies can be used by the CDs of FIG. 5.
Cellular phones supporting LTE can support packet-switched voice and packet-switched data communications and thus may operate as IMS-compliant mobile devices. In this embodiment, the cellular base station 521 may communicate directly with the IMS network 550 as shown by the arrow connecting the cellular base station 521 and the P-CSCF 516.
Alternative forms of a CSCF can operate in a device, system, component, or other form of centralized or distributed hardware and/or software. Indeed, a respective CSCF may be embodied as a respective CSCF system having one or more computers or servers, either centralized or distributed, where each computer or server may be configured to perform or provide, in whole or in part, any method, step, or functionality described herein in accordance with a respective CSCF. Likewise, other functions, servers and computers described herein, including but not limited to, the HSS, the ENUM server, the BGCF, and the MGCF, can be embodied in a respective system having one or more computers or servers, either centralized or distributed, where each computer or server may be configured to perform or provide, in whole or in part, any method, step, or functionality described herein in accordance with a respective function, server, or computer.
The software-defined network server 430 of FIG. 4 can be operably coupled to communication system 500 for purposes similar to those described above. The software-defined network server 430 can perform function 462 and thereby provide access to back-end services to the CDs 501, 502, 503 and 505 of FIG. 5 similar to the functions described for SDN controller 124, 224 of FIGS. 1 and/or 2 in accordance with method 300 of FIG. 3. CDs 501, 502, 503 and 505, which can be adapted with software to perform function 572 to utilize the services of the software-defined network server 430 similar to the functions described for the mobile device 104, 204 of FIGS. 1 and/or 2 in accordance with method 300 of FIG. 3. The software-defined network server 430 can be an integral part of the application server(s) 517 performing function 574, which can be substantially similar to function 462 and adapted to the operations of the IMS network 550.
For illustration purposes only, the terms S-CSCF, P-CSCF, I-CSCF, and so on, can be server devices, but may be referred to in the subject disclosure without the word “server.” It is also understood that any form of a CSCF server can operate in a device, system, component, or other form of centralized or distributed hardware and software. It is further noted that these terms and other terms such as DIAMETER commands are terms can include features, methodologies, and/or fields that may be described in whole or in part by standards bodies such as 3rd Generation Partnership Project (3GPP). It is further noted that some or all embodiments of the subject disclosure may in whole or in part modify, supplement, or otherwise supersede final or proposed standards published and promulgated by 3GPP.
