Abstract

A mechanism is disclosed for facilitating the performance of communication services in a communication network. An enhanced proxy server receives a signaling message and proxies the message to an application server. Further, the enhanced proxy server responds to the message by extracting a set of data from a data store and making the set of data available for use by the application server in responding to the signaling message. Similarly, a registration server may receive a signaling message from a communicating entity and may responsively make data available for use by an application server in responding to signaling messages regarding the communicating entity.

12. A method comprising:

transporting an initiation message over a radio access network from a wireless mobile station to a packet-switched network, the initiation message being indicative of a request from a user of the wireless mobile station to engage in a communication;

transmitting the initiation message over the packet-switched network to a signaling proxy server, and receiving the initiation message into the signaling proxy server;

in response to the initiation message, the signaling proxy server extracting from a data store a set of data usable by an application server to set up the communication; and

the signaling proxy server forwarding the initiation message to the application server and making the set of data available for use by the application server in responding to the initiation message.

13. The method of claim 12, further comprising:

the application server receiving the initiation message and using the set of data to set up the communication.

14. The method of claim 13, wherein the set of data comprises a buddy-list designated for the user.

15. The method of claim 14, wherein the application server comprises a push-to-talk server (PTT) and the communication comprises a PTT session.

16. The method of claim 14, wherein the application server comprises an instant messaging (IM) server, and the communication comprises an IM communication.
