Abstract

Disclosed are a method, a User Equipment (UE) and a system for providing a simultaneous multiple session Push-to-talk over Cellular (PoC) multimedia service. A PoC client performing a PoC multimedia communication service participates in multiple sessions according to the setup of a user, and can simultaneously receive the same media streams without filtering in a PoC server when the same media streams are transmitted. Further, the PoC client can set a session, to which filtering is to be applied, from among a plurality of sessions and media types.

Claims

1. A system for providing a simultaneous multiple session Push-to-talk over Cellular (PoC) multimedia service, the system comprising:

at least one PoC User Equipment (UE) for transmitting a simultaneous multiple service request message for requesting a simultaneous multiple service, in order to simultaneously receive at least one stream with an equal multimedia type through multiple sessions; and

a PoC server for providing, if the simultaneous multiple service request message is received, said at least one PoC UE with multimedia streams, which are specified by the simultaneous multiple service request message, through the multiple sessions.

2. The system as claimed in claim 1, wherein the PoC UE transmits the simultaneous multiple service request message to the PoC server before session origination, and thus sets the simultaneous multiple service.

3. The system as claimed in claim 1, wherein the PoC UE transmits the simultaneous multiple service request message for applying the simultaneous multiple session multimedia service only to a corresponding session to the PoC server while a session is in progress, and thus sets the simultaneous multiple service, the simultaneous multiple service request message including an Identifier (ID) of a corresponding session to which a service is to be applied.

4. The system as claimed in claim 1, wherein the simultaneous multiple service request message includes at least one of both a multimedia type for the request of the simultaneous multiple service and a maximum number of multimedia PoC sessions.

5. A method for providing a simultaneous multiple session Push-to-talk over Cellular (PoC) multimedia service, the method comprising the steps of:

transmitting, by a PoC User Equipment (UE), a simultaneous multiple service request message for requesting a simultaneous multiple service, in order to simultaneously receive at least one stream with an equal multimedia type through multiple sessions; and

providing, by a PoC server, said at least one PoC UE with multimedia streams for the request of the simultaneous multiple service through the multiple sessions, if the simultaneous multiple service request message is received.

6. The method as claimed in claim 5, further comprising transmitting, by the PoC UE, the simultaneous multiple service request message to the PoC server before session origination, thereby setting the simultaneous multiple service.

7. The method as claimed in claim 5, further comprising transmitting, by the PoC UE, the simultaneous multiple service request message for applying the simultaneous multiple session multimedia service only to a corresponding session to the PoC server while a session is in progress, thereby setting the simultaneous multiple service, the simultaneous multiple service request message including an Identifier (ID) of a session to which a service is to be applied.

8. The method as claimed in claim 5, wherein the simultaneous multiple service request message includes at least one of a multimedia type for the request of the simultaneous multiple service and a maximum number of multimedia PoC sessions.

9. A PoC User Equipment (UE) for providing a simultaneous multiple session Push-to-talk over Cellular (PoC) multimedia service, the PoC UE comprising:

a data transmitter for performing packet data transmission/reception with a PoC server;

a controller for transmitting a service request message for requesting a simultaneous multiple service, in order to simultaneously receive at least one stream with an equal multimedia type through multiple sessions, and performing data processing for displaying multimedia data received through the data transmitter; and

a display unit for receiving and displaying the data processed by the controller.

10. A method for providing, by a PoC User Equipment (UE), a simultaneous multiple session Push-to-talk over Cellular (PoC) multimedia service, the method comprising the steps of:

generating a simultaneous multiple service request message for requesting a simultaneous multiple service, in order to simultaneously receive at least one stream with an equal multimedia type through multiple sessions; and

transmitting the generated simultaneous multiple service request message to a PoC server.
