## Background
RELATED APPLICATION
U.S. patent application Ser. No. 11/539,801, filed Oct. 9, 2006, by Gorti et al., entitled “Method and Apparatus for Delivering Portal Services,” incorporated herein by reference in its entirety.
FIELD OF THE DISCLOSURE
The present disclosure relates generally to communication systems, and more specifically to a method and apparatus for delivering IP Multimedia Subsystem (IMS) services.
BACKGROUND
As IP Multimedia Subsystem (IMS) Services grow in popularity, an increasing number of data and multimedia applications are envisioned for fixed and mobile IP-based communication devices. Currently, each IMS application establishes a new user interface at a terminal device. This approach is similar to the days when each software application essentially had its own look and feel, thereby resulting in the creation of various windowing systems to address this problem.
Today's IMS services are deployed according to a static model. That is, communication devices operating in a wired or wireless access network (WAN) such as shown in the prior art system of FIG. 1 have one or more IMS clients and applications loaded on them that are pre-provisioned with credentials (e.g., user name/password, HTTP digest, etc.). Each IMS client is supplied by a corresponding IMS service provider. Accordingly, each of these clients is pre-configured to point to a particular IMS service provider. The end user of a communication device utilizing these clients is thereby forced to subscribe with each corresponding IMS service provider on a fixed subscription.
As a result of this static model there is no easy way for a roaming user to subscribe to an IMS service on a temporary basis. A need therefore arises for a method and apparatus that delivers IMS services.

DETAILED DESCRIPTION OF THE DRAWINGS
Embodiments in accordance with the present disclosure provide a method and apparatus for delivering IP Multimedia Subsystem (IMS) services.

In a fifth embodiment of the present disclosure, a method in which a broker aggregates IMS services of one or more IMS service providers for presentation to one or more terminal devices.
FIG. 2 depicts an exemplary embodiment of a communication system 200. The communication system 200 can comprise a number of Wireline or Wireless Access Networks (WANs) 216 which support any number of access point technologies such as Public Switched Telephone Network (PSTN), xDSL, cable, WiFi, WiMAX, cellular (e.g., GSM, CDMA, UMTS, etc.), Bluetooth, software defined radio (SDR), ultra wide band (UWB), and so on. In one of several embodiments, WANs 116 can represent, for example, WiFi hotspots established by retailers to draw patrons to their establishment for additional business.
Terminal devices 214 can represent single or multimode roaming communication devices capable of interfacing to the WANs 216 by wire or wirelessly. The terminal devices 214 can represent a number of embodiments including without limitation computing devices (e.g., a laptop computer), a cellular phone with multimode capability (e.g., WiFi and cellular), and a personal digital assistant (PDA) with wireless capability. Accordingly, an end user of a terminal device 214 can operate from or roam into a WAN 216 of a residence or commercial enterprise and utilize wireless or wireline communication services of the communication system 200.
The WANs 216 can be coupled to a packet-switched (PS) network 218 (e.g., an IP, Frame Relay, Asynchronous Transfer Mode or ATM, Multi-protocol Label Switching or MPLS). The PS network 118 can be managed by, for example, a Tier 1 Internet Service Provider (ISP) utilizing common packet-switched routing technologies. A system 202 can be coupled to the PS network 218 to supply aggregated IP Multimedia Subsystem (IMS) services to roaming terminal devices 214 by way of the WANs 216.
IMS is a standardized Next Generation Network (NGN) architecture that converges mobile and fixed multimedia services. IMS can support Voice over IP (VoIP) based on a 3GPP (3rd Generation Partnership Project) standardized implementation of Session Initiation Protocol (SIP), and can operate over a standard Internet protocol (IP) network. Existing phone systems utilizing packet-switched or circuit-switched techniques can be supported by IMS. Accordingly, IMS aims to provide current and future communication services that the Internet can support. In this way, IMS gives service providers the ability to control and charge for services in an integrated fashion. To achieve these objectives, IMS uses open standard protocols defined by the Internet Engineering Task Force (IETF).
System 202 can be managed by an IMS services broker or aggregator. System 202 can thus serve as a clearing house for IMS service providers targeting consumers that may not be readily accessible in networks managed by said providers. System 202 can be operated by an independent broker, or can be managed by the service provider of the PS network 218. In some instances, the broker can be associated with one or more WANs 216. Consequently, the broker managing operations of system 202 can be any of the parties providing communication services in FIG. 2. Due to the nature of terminal devices 214 roaming in and out of WANs 216, IMS services offered by system 202 can be temporary. That is, while the terminal device 216 is in the vicinity of a WAN 216 it can receive IMS services it has temporarily subscribed to. Once the terminal device 216 departs from the WAN 216 or the services subscribed to have expired according to a given time limit, the terminal device 216 must re-subscribe to acquire IMS services within the same or new WAN 216.
To accomplish the foregoing activities, system 202 comprises an aggregator element 204, a processing element 206, a presentation element 208 and a communication element 210. The aggregator element 204 serves to aggregate IMS services from one or more IMS service providers (see reference 212) as a web service. The processing element 206 can represent a computing device (such as a scalable server) that manages operations of system 202. The presentation element 208 serves to present a web page with sub-frames showing the aggregated IMS services of one or more IMS service providers to roaming terminal devices 214 requesting service from system 202. IMS services can be bundled in any desirable manner. For instance, each IMS service can be presented with its corresponding IMS service provider, or IMS services can be logically bundled across more than one IMS service provider to provide, for example, a full service package (voice, video and data). The aggregator element 204 and the presentation element 208 can be an integral part of each other. The communication element 210 provides a means of communication between the IMS service providers and the PS network 218 utilizing common packet-switched technologies.
FIG. 3 depicts an exemplary embodiment of a terminal device 214. Terminal devices 214 can comprise a communication element 302, a processing element 304, a presentation element 306, and a browser element 308. The communication element 302 can comprise common communications technology to support wireline and/or wireless communications conforming to the communication protocols previously described for the WANs 216. The processing element 204 can comprise a computing device such as a microprocessor and/or Digital Signal Processor (DSP) for managing operations of the terminal device 214. The presentation element 306 can comprise a common display such as a Liquid Crystal Display (LCD) accompanied by an audio system for presenting visual and/or audio signals to an end user of the terminal device 214. The browser element 308 can represent a common browser for navigating through services provided by the Internet.
The foregoing elements of system 202 and the terminal device 214 can be implemented with common software and/or hardware techniques.
FIG. 4 depicts an exemplary method 400 operating in portions of the communication system 200. Method 400 begins with step 402 in which the system 202 aggregates a number of IMS services of one or more IMS service providers according to common aggregation techniques. This step can occur once or periodically as IMS services are added or removed by the broker of system 202. In step 404, system 202 detects a terminal device 214 roaming into a WAN 216. The detection step can represent, for example, a WiFi access point that detects the presence of a terminal device 214 in its network and submits a notification to system 202. Once detected, the system 202 transmits a web page with the aggregated IMS services which is presented at the terminal device 214 by the browser element 308. The web page can include advertisements, hyperlinks to the IMS services as well as instructions for how to enable any one or more of the IMS services offered.
In step 408, system 202 awaits a selection from the terminal device 214. The browser element 308 can provide an end user of the terminal device 214 a means to navigate through the web page to make one or more IMS service selections. Once a selection is made, the terminal device 214 transmits the selected services to system 202 which is intercepted by system 202 in step 410. From step 410, system 202 can proceed to steps 412-414 or 416. In steps 412-414, the terminal device 214 submits authentication information (e.g., login information, personal identification number or PIN code, etc.) to system 202, which processes said information and authorizes, or rejects the request to enable the IMS services selected.
The authorization information supplied by the terminal device 214 can be processed according to a Remote Authentication Dial-In User Service (RADIUS) protocol operating in system 202. RADIUS is an Authentication, Authorization and Accounting (AAA) protocol for network access applications or IP mobility. Steps 412-414 can be used, for example, in cases where the terminal device 214 is an existing subscriber of system 202 for accessing IMS services while roaming in the communication system 200. If the authorization process fails in step 414, system 202 can proceed to step 412 where it can request that terminal 214 retransmit again the authentication information. System 202 can alternatively send a notification to the end user of terminal device 214 indicating that authorization has been denied and that no further attempts are allowed if too many attempts have been made by said user.
Alternatively or in combination with steps 412-414, the system 202 can submit to the terminal device 214 a request for payment information. The payment information can represent a credit card, or prepaid card information. The end user of the terminal device 214 can enter payment information by common means such as a keypad, or the payment information can be pre-stored in the terminal device 214 and submitted to system 202 on demand. Once the payment information is received by system 202, it is processed in step 418. If valid, the system 202 proceeds to step 417 where it downloads one or more IMS clients (e.g., a SIP client or ActiveX control of the web page) tailored to the one or more IMS services selected in step 410. This embodiment differs with the prior art system of FIG. 1 in that the IMS clients downloaded can be customized or generated by system 202 according to the IMS services selected rather than a static model in which the IMS client cannot change unless an updated IMS client is supplied by the IMS service provider of the prior art system. Moreover, in the present disclosure the IMS client downloaded in step 417 can support the selection of IMS services across several independent IMS service providers. In the prior system of FIG. 1, an IMS client is required for each independently operated IMS service provider.
In the present context, an IMS client can represent for instance a software application that supports some form of IMS data services. For example, one of the IMS clients downloaded to the terminal device 214 in step 417 can be a soft phone for VoIP services. There are innumerable other possible IMS services such as, for example, a video communications service (such as H.323), a gaming service, a music service, a video entertainment service, a location-based service (LBS), a news service, a weather service, a sports service, an education service, or an address book service—just to name a few. An IMS client downloaded to the terminal device 214 can support IMS services from disparate IMS service providers as discussed earlier, or system 202 can generate a number of IMS clients each tailored to a specific IMS service provider according to the IMS services selected for said provider.
Following step 417 the system 202 temporarily enables in step 420 the selected IMS services. After the IMS services are enabled, system 202 in cooperation with the IMS service provider(s) supplying the selected IMS services can negotiate with the WAN 216 a Quality of Service (QoS) for delivering said IMS services to the terminal device 214. The IMS services selected can be, for example, enabled over a 24 hour period with the ability to logoff and on to said IMS services multiple times, or can be limited for use while the terminal device 214 is operating in the WAN 216, and terminated once its roams outside of the WAN's communication range. For example, in steps 419 and 421 system 202 can be programmed to check for the expiration of the IMS services selected. Once the IMS services have expired, system 202 can be programmed to disable said services, and if necessary remove the IMS clients downloaded to the terminal 214.
From this point, system 202 can proceed to step 422 where it can submit a charge to an account associated with the terminal device 214. In this embodiment, charges can be based on usage of IMS services rather than a fixed service fee. Accordingly, system 202 does not submit a charge until it has made an accounting of the usage in time of IMS services and/or other interactions with the IMS services (e.g., content downloads) monitored by system 202. Once payment for said services is received by system 202 or the IMS service provider in step 424, revenue is shared between the broker managing system 202 and the IMS service provider associated with the IMS services selected.
It would be evident to an artisan with ordinary skill in the art that the aforementioned embodiments can be modified, reduced, or enhanced without departing from the scope and spirit of the claims described below. For example, as previously described a number of steps in method 300 can be removed or rearranged without departing from the scope of the claims. Similarly, other common payment techniques not mentioned in the present disclosure can be applied without departing from the scope of the claims. Accordingly, the reader is directed to the claims below for a fuller understanding of the breadth and scope of the present disclosure.
