SYSTEM AND METHOD FOR SIGNALING OPTIMIZATION IN IMS SERVICES BY USING A SERVICE DELIVERY PLATFORM
First Claim
1. A method of reducing signaling traffic in the provision of data services to a plurality of user endpoints (UEs), the UEs being in communication with a radio access network, the radio access network being in communication with an IP multimedia subsystem (IMS) core for providing data service to the UEs, the data service including a videoshare service, the method comprising:
- providing an application server (AS) that during operation communicates with the IMS core and serves as a data service registrar for the UEs, andproviding logic in the AS configured to;
receive from a first UE of the plurality of UEs videoshare capabilities information of the first UE;
cache the first UE videoshare capabilities information; and
send to a second UE of the plurality of UEs the cached first UE videoshare capabilities information.

Abstract
Systems and methods for reducing signaling traffic in the provision of data services to a plurality of user endpoints (UEs). The UEs are in communication with a radio access network, which is the in communication with an IP multimedia subsystem (IMS) core for providing data service to the UEs, the data service including a videoshare service. The systems and methods involve providing an application server (AS) that during operation communicates with the IMS core and serves as a data service registrar for the UEs, and providing logic in the AS configured to receive from a first UE of the plurality of UEs videoshare capabilities information of the first UE, cache the first UE videoshare capabilities information and send to a second UE of the plurality of UEs the cached first UE videoshare capabilities information.

4. A method of reducing signaling traffic in the provision of data services to a plurality of user endpoints (UEs), the UEs being in communication with a radio access network, the radio access network being in communication with a circuit-switched network for providing voice service to the UEs and with an IP multimedia subsystem (IMS) core for providing data service to the UEs, the method comprising:
-
providing an application server (AS) that during operation communicates with the IMS core and serves as a data service registrar for the UEs; and providing logic in the AS configured to; receive a registration request from a first UE of the plurality of UEs; after receiving the registration request from the first UE, initiate a capabilities exchange process with the first UE; receive first UE capabilities information sent by the first UE during the capabilities exchange process; cache the received first UE capabilities information; and respond to a request received from a second UE of the plurality of UEs for the first UE capabilities information by retrieving from an AS cache and sending to the second UE the cached first UE capabilities information. - View Dependent Claims (5, 6)

7. A method of reducing signaling traffic in the provision of data services to a plurality of user endpoints (UEs), the UEs being in communication with a radio access network, the radio access network being in communication with a circuit-switched network for providing voice service to the UEs and with an IP multimedia subsystem (IMS) core for providing data service to the UEs, the method comprising:
-
providing an application server (AS) that during operation communicates with the IMS core and with the circuit-switched network and that serves as a data service registrar for the UEs; and providing logic in the AS configured to; receive a registration request from a first UE of the plurality of UEs; after receiving the registration request from the first UE, initiate a capabilities exchange process with the first UE; receive first UE capabilities information sent by the first UE during the capabilities exchange process; cache the received first UE capabilities information; and when the first UE is connected to a second UE via the circuit-switched network, obtain the IP addresses of the first and second UEs using information retrieved from the circuit-switched network, retrieve from an AS cache the cached first UE capabilities information corresponding to the first UE IP address, and send the cached first UE capabilities information to the second UE via the IMS core using the second UE IP address. - View Dependent Claims (8)

9. A method of reducing signaling traffic in the provision of data services to a plurality of user endpoints (UEs), the UEs being in communication with a radio access network, the radio access network being in communication with a circuit-switched network for providing voice service to the UEs and with an IP multimedia subsystem (IMS) core for providing data service to the UEs, the data service including a presence service provided by a presence AS in communication with the IMS core, the method comprising:
-
providing a registering application server (AS) that during operation communicates with the IMS core and serves as a data service registrar for the UEs; providing logic in the registering AS configured to retrieve from a first UE capabilities information for the first UE when the first UE registers with the IMS core, to retrieve from a second UE capabilities information for the second UE when the second UE registers with the IMS core, and to cache the first and second UE capabilities information; and providing logic in the presence AS configured to store a contact list of a first UE and, if a user corresponding to the second UE is in the first UE contact list, retrieve from the registering AS capabilities information for the second UE and send the second UE capabilities information to the first UE. - View Dependent Claims (10)
