Abstract

A system and method of a multimedia Push-To-Talk (PTT) over Cellular (PoC) box service is provided which can reflect dynamic requests of a user using a function for interworking with a PoC server and an Extensible Markup Language (XML) Document Management Server (XDMS) in a PoC system. In a method for providing the PoC box service, the PoC XDMS stores various information about a type of media to be stored by a PoC user, a PoC box type, and a connection address after a service request expires. An associated service is implemented by Session Initiation Protocol (SIP) technology between the PoC server and a PoC client and by interworking with the PoC server and the XDMS.

Claims

sending and storing the PoC box service information from the XDMC to the server when the PoC box service information is input; and

providing the PoC box service from the PoC server according to the PoC box service information mapped to the PoC client stored in the PoC box service information storage server when a session request for the PoC client is present.

2. The method of claim 1, further comprising:

sending a PoC box service activation request message from the PoC client to the PoC server when an input for activating the PoC box service is present; and

activating the PoC box service for an associated PoC client when the PoC server receives the PoC box service activation request message.

3. The method of claim 1, wherein the sending and storing step further comprises:

generating PoC box service parameters in response to the PoC box service information input;

sending a PoC box service information setting request message including the generated PoC box service parameters to the PoC box service information storage server through an aggregation proxy server; and

storing the PoC box service parameters included in the message when the PoC box service information storage server receives the PoC box service information setting request message.

4. The method of claim 3, wherein the PoC box service setting request message is an XML document including the PoC box service parameters.

5. The method of claim 3, wherein the PoC box service setting request message is a Hyper Text Transfer Protocol (HTTP) PUT message, and includes Uniform Resource Identifier (URI) information for setting the PoC box service parameters and setting up a session.

6. The method of claim 3, wherein the PoC box service setting request message is sent to the PoC box service information storage server using an XML Configuration Access Protocol (XCAP).

7.

sending, to the XDMC, a response message including information indicating whether the PoC box ID is available.

9. The method of claim 7, further comprising:

generating a PoC box ID when the PoC box ID is not included in the PoC box service information setting request message received by the PoC box service information storage server; and

sending, to the XDMC, a response message including the generated PoC box ID.

10. The method of claim 1, wherein the providing step comprises:

sending, to the PoC box service information storage server, a request for PoC box service information mapped to the PoC client when the PoC server receives a session request message for the PoC client;

providing stored PoC box service information mapped to an associated PoC client from the PoC box service information storage server to the PoC server in response to the PoC box service information request; and

sending the session request message to an associated PoC box according to the PoC box service information when the PoC server receives the PoC box service information.

11. The method of claim 1, wherein the providing step comprises:

sending, to the PoC box service information storage server, a request for stored PoC box service information mapped to the PoC client;

providing the stored PoC box service information mapped to the PoC client to the PoC server in response to the PoC box service information request; and

storing the PoC box service information when the PoC server receives the PoC box service information and sending a session request message to an associated PoC box according to the PoC box service information when the PoC server receives the session request message for the PoC client.

12. The method of claim 10, further comprising:

automatically sending a response message to generate a session when the PoC box receives the session request message; and

transmitting a media stream mapped to a media type set by the PoC box service information from the PoC server to the PoC box after the session is generated.

13. A Push-To-Talk (PTT) over Cellular (PoC) system for providing a PoC box service, comprising:

a PoC User Equipment (UE) including a PoC Extensible Markup Language (XML) Document Management Client (XDMC) for sending PoC box service information to a server for storing the PoC box service information through an aggregation proxy server when the PoC box service information is input;

the XDMC for mapping the sent PoC box service information to the PoC UE and storing the mapped information; and

a PoC server for providing a PoC box service according to the PoC box service information, mapped to a PoC client, stored in the PoC box service information storage server when a session request for the PoC client is present.

14. The PoC system of claim 13, wherein the PoC UE further comprises the PoC client for sending a PoC box service activation request message to the PoC server when an input for activating the PoC box service is present, and
