Abstract: A central terminal may receive from a user a first message, which may be transmitted from a communication terminal, identifying particular media content on a particular content server, and in response the central terminal may transmit a second message to a particular application server if the central terminal determines that the first message is associated with the application server. The application server may generate and transmit to the communication terminal accessing information that may be used by the user to retrieve, via the communication terminal, the media content from the content server. Submitting content requests in this manner may enable routing content requests through a particular system, such as IP Multimedia Subsystem (IMS), thereby making use of filtering features of the particular system for user authentication and access control, and obviating need for separate proprietary access control mechanisms for the content server.

Abstract: For providing to a user on a communication terminal (1) media content (31) from a content server (3), a Session Initiation Protocol message, addressed to a resource identifier identifying the media content (31), is transmitted from the communications terminal (1) to a Call Session Control Function unit (S-CSCF), in response to the user activating a hyperlink associated with the media content (31). If there are filter criteria (iFC) associated with the user and associating the first message with an application server (SIP-AS), the resource identifier is transmitted from the Call Session Control Function unit (S-CSCF) to the application server (SIP-AS). The application server (SIP-AS) transmits to the communication terminal (1) accessing means for the user to retrieve the media content (31) from the content server (3).

Abstract: A method of controlling subscriber access to SIP-based services facilitated by an IP Multimedia Subsystem. The method comprises defining at a Serving Call Session Control Function node at least one default screening trigger, and downloading from a Home Subscriber Subsystem, specific screening triggers allocated to at least certain subscribers. At the Serving Call Session Control Function node, at least certain SIP messages originating at subscriber terminals are intercepted and, for each intercepted message and in the absence of a matching specific screening trigger, the default trigger is activated so as to cause the SIP message to be forwarded to a specific SIP application service.

Abstract: For subscribing a user to a service offered by a first application server (SIP-AS1) of an Internet Protocol Multimedia Subsystem, a request for the service, addressed to a public service identifier of the service, is received from the user in a Call Session Control Function unit (S-CSCF). The request is evaluated based on filter criteria (iCF) associated with the user. In absence of the filter criteria (iCF) associating the service with the first application server (SIP-AS1), the request is forwarded to a second application server (SIP-AS2) based on addressing information obtained from filter criteria (FC) associated with the public service identifier. The second application server (SIP-AS2) transmits to the user a message that includes means for enabling the user to subscribe to the service. Users can be subscribed to a service at the time they desire to use the service, immediately preceding usage of the service.

Abstract: A method and system for selecting a Multimedia Resource Function Controller (MRFC) for allocating resources for a conference call based on a pre-defined condition. In a first embodiment, the condition is associated with a status of an MRFC of a first network, such as an overload of resources, a failure, or an inexistence of the MRFC in the first network. When the condition is detected, an application server (AS) of the first network delegates the responsibility of allocating the resources for the conference call to an MRFC of a second network. In a second embodiment, the pre-defined condition is associated with a location of a User Equipment (UE) involved in the conference call. Based on the UE's location, the AS of the first network selects an MRFC of a second network, and delegates the responsibility of allocating the resources for the conference call to the MRFC of the second network.

Abstract: A system and method of accessing services from end terminals disposed in an integrated telecommunications network having a packet-switched network (PSN) portion such as, for example, a network portion using the Internet Protocol (IP) and a circuit-switched network (CSN) portion such as, for example, a wireless telephony network portion. A generalized service invocation and realization architecture includes one or more call control modules modified to include service-related Detection Points (DPs), a Service Access component or instance that is created when a new DP is encountered, and one or several service proxies which invoke services on behalf of the Service Access component and mediate between the call control modules and services. A common Service Logic Environment is implemented for local services, mobile agent services, and remote services. The PSN portion is preferably realized as a Voice-over-IP (VoIP) network having a gateway connected to the CSN portion.

Abstract: A method, system and Application Server (AS) for distributing Push-To-Talk (PTT) voice and multimedia messages to communities of subscribers, using a definition os PTT groups. First, a PTT group of subscribers is created in the AS, either by one of the members or by a content provider server. Then, the subscribers register their interest in receiving PTT messages related to the created group, for example by joining a Session Initiation Protocol (SIP) related to that group. Finally, the content provider server sends a PTT message destined to the PTT group, the message comprising voice and/or multimedia information, such as for example news, stock quotes, sport updates, weather or commercial information. The message is received by the AS, which distributes it to the registered subscribers of the PTT group using its definition of the PTT group.

Abstract: A method and system for exchanging instant messages among participants to a conference call, wherein when an instant message is to be sent among the participants, the instant message is addressed by a first participant to the conference call itself, which is identified by a conference call URI. An Application Server (AS) receives the message, and based on a memory-stored correspondence between the conference call URI and the conference call participants, translates the session URI into Public Ids, SIP URIs or any other identifier of each participant, or participant's terminal. The AS further relays the instant message to the other participants by addressing it to each participant's identifier. The memory of the AS is updated as new participants join or leave the conference call, as to always reflect the participants currently involved in the conference call.
