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

1. A method for managing a Push-To-Talk (PTT) over Cellular (PoC) box service in a PoC User Equipment (UE) in a PoC system, wherein the PoC system comprises the PoC UE including a PoC Extensible Markup Language (XML) Document Management Client (XDMC) and a PoC client, a PoC server, a PoC box service information storage server for storing PoC box service information, and a PoC box, the method comprising the steps of:

generating PoC box service information for providing a PoC box service;

sending, by the XDMC, a PoC box service information setting request message including the PoC box service information and storage request information for requesting storage of the PoC box service information to the PoC box service information storage server;

receiving, by the XDMC, a first response message including a PoC box service Identifier (ID) mapping the PoC box service information stored in the PoC box service information storage server, from the PoC box service information storage server;

processing a session connection with the PoC server; and

sending a media data to be stored in the PoC box, through the PoC server, to the PoC box.

2. The method of claim 1, wherein the PoC box service information includes at least one parameter of a PoC box type for indicating whether a UE PoC box or a network PoC box is used, a type of media to be transmitted to the PoC box, a maximum storage size and time, a type of codec to be used when media is stored in the PoC box, an answer mode of the PoC box, a PoC box Identifier (ID), and a PoC box service related information to be used when a PoC box service activation request message has expired.

3. The method of claim 2, wherein the PoC box service information setting request message includes the PoC box service ID and the first response message includes information indicating whether the PoC box ID is available.

4. The method of claim 2, wherein the PoC box service information setting request message does not include the PoC box service ID and the first response message incudes the PoC box service ID generated by the PoC box service information storage server.

5. The method of claim 1, further comprising:

sending a PoC box service activation request message including a value of indicating whether the PoC box service is activated to the PoC server; and

receiving a second response message in response to the PoC box service activation request message from the PoC server.

6. The method of claim 5, wherein the PoC box service activation request message comprises at least one of PoC UE address information and the PoC box service ID.

7. The method of claim 5, wherein the PoC box service information setting request message is sent to the PoC box service information storage server using an XML Configuration Access Protocol (XCAP).

8. The method of claim 1, wherein the PoC box service information setting request message is an XML document including the PoC box service information.

9. The method of claim 1, wherein the PoC box service information 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 information and setting up a session.

10. The method of claim 1, wherein the PoC box is comprised in at least one of a network and another PoC UE different from the PoC UE comprised in the PoC system.

11. A method for managing a Push-To-Talk (PTT) over Cellular (PoC) box service in a PoC server in a PoC system, wherein the PoC system comprises a PoC User Equipment(UE) including a PoC Extensible Markup Language (XML) Document Management Client (XDMC) and a PoC client, the PoC server, a PoC box service information storage server for storing PoC box service information, and a PoC box, the method comprising the steps of:

receiving a PoC box service activation request message from the PoC UE;

receiving a session request message from the PoC UE;

sending a PoC box service information request message for requesting the PoC box service information to the PoC box service information storage server for providing a PoC box service;

receiving the PoC box service information mapped to the PoC client from the PoC box service information storage server;

setting a session with the PoC box corresponding to the PoC box service information; and

receiving media data to be stored in the PoC box and sending the media date-data to the PoC box based on the PoC box service information.

12. The method of claim 11, wherein the PoC box service activation request message includes a value indicating whether the PoC box service is activated.

13. The method of claim 11, wherein the PoC box service activation request message includes at least one of PoC UE address information and a PoC box service ID including information for mapping the PoC box service information stored in the PoC box service information storage server.

14. The method of claim 11, wherein the box service information request message comprises at least one of PoC UE address information and a PoC box service ID comprising information of mapping the PoC box service information stored in the PoC box service information storage server.

15. The method of claim 11, further comprising:

storing the PoC box service information received from the PoC box service information storage server into the PoC server.

16. A Push-To-Talk (PTT) over Cellular (PoC) User Equipment (UE) in a PoC system, the PoC UE comprising:

a PoC Extensible Markup Language (XML) Document Management Client (XDMC) for generating a PoC box service information for providing a PoC box service, sending a PoC box service information setting request message including the PoC box service information and storage request information for requesting storage of the PoC box service information to a PoC box service information storage server, and receiving a first response message including a PoC box service Identifier (ID) mapping the PoC box service information stored in the PoC box service information storage server, from the PoC box service information storage server; and

a PoC client for processing a session connection with a PoC server and sending media data to be stored in a PoC box, through the PoC server, to the PoC box.

17. The PoC UE of claim 16, wherein the PoC client sends a PoC box service activation request message including a value indicating whether the PoC box service is activated to the PoC server, and receives a second response message in response to the PoC box service activation request message from the PoC server.

18. A Push-To-Talk (PTT) over Cellular (PoC) server in a PoC system, the PoC server including a processor for:
