Abstract

A media content transmission method disclosed herein includes: The network-side equipment receives a first message containing the media content, includes the received media content into a second message, and then transmits the second message. A network-side equipment is also provided herein.

Claims

1. A method for transmitting media content, comprising:

receiving a first message containing media content;

including the media content contained in the first message into a second message, and

sending the second message.

2. The method of claim 1, before including media content brought in the first message into the second message, further comprising:

generating the second message which is used to carry the media content.

3. The method of claim 1, before including media content brought in the first message into the second message, further comprising:

generating a user-plane message;

sending the user-plane message to a client to inform that a session has been established.

4. The method of claim 1, before receiving the first message containing media content, further comprising:

receiving Session Initiation Protocol (SIP) Subscribe message containing a state of required media content.

5. The method of claim 1, wherein the second message including the media content is any one of the following:

SIP message;

Real-time Transport Protocol (RIP) message;

Real-time Transport Control Protocol (RTCP) message;

Message Session Relay Protocol (MSRP) message; and

extended protocol message.

6. The method of claim 1, wherein the format of the media content is text format or multimedia format.

7. The method of claim 1, further comprising:

initiating a session using a pre-established session between a client and a Push to Talk over Cellular (PoC) sever, before the PoC server receives the first message containing media content.

8. The method of claim 7, wherein:

the first message is received by the PoC server from the client through a SIP/IP core network; and

the second message is sent by the PoC server to a called party network.

9. The method of claim 8, wherein the first message is a SIP REFER message;

and the second message is a SIP INVITE message.

10. The method of claim 7, wherein:

the first message is received by the PoC server from a SIP/IP core network; and

the second message is sent by the PoC server to the client through the SIP/IP core network.

11. The method of claim 10, wherein the first message is a SIP INVITE message;

and

the second message is a SIP INVITE message.

12. A method for transmitting media content, comprising:

receiving a message containing referenced media content or text content;

generating a user-plane message, and including the referenced media content or text content into the user-plane message; and

sending the user-plane message.

13. The method of claim 12, further comprising:

initiating a session using a pre-established session between a PoC sever and a client before the PoC server receives the message containing referenced media content or text content.

14. The method of claim 13, wherein:

the message containing referenced media content or text content is received by the PoC sever from a SIP/IP core network; and

the user-plane message is sent by the PoC sever to the client through the SIP/IP core network.

15. The method of claim 14, wherein after performing the step of sending the user-plane message by the PoC sever to the client through the SIP/IP core network, further comprising:

obtaining the media content by the client according to referred media content.

16. The method of claim 13, wherein the message containing referenced media content or text content is a SIP message.

17. The method of claim 13, wherein the user-plane message is generated according to RTP, RTCP, or Talk Burst Control Protocol (TBCP).

18. A network-side equipment, comprising:

a receiving unit, adapted to receive a first message containing media content; and

an embedding unit, adapted to;

include the media content contained in the first message into a second message, and send the second message.

19. The network-side equipment of claim 18, wherein the network-side equipment is a PoC server.
