Abstract

Provided are a method and device for media multiplexing negotiation. The method comprises: sending a negotiation request message to a response end, the negotiation request message comprising information about n media types; and receiving a negotiation response message sent by the response end, the negotiation response message being used for indicating m multiplexing relationships, each multiplexing relationship of the m multiplexing relationships corresponding to at least one media type of the n media types, and each multiplexing relationship being used for indicating at least one media type which uses the same port number to conduct transmission, where n is a positive integer, and m is a positive integer which is smaller than n.

First claim

What is claimed is:

1 . A method for media multiplexing negotiation, comprising:
receiving a negotiation request message transmitted from a requesting end, wherein the negotiation request message comprises information on n media types; determining a negotiation response message according to the negotiation request message, wherein the negotiation response message is configured to indicate m multiplexing relationships, each multiplexing relationship of the m multiplexing relationships corresponds to at least one media type of the n media types and each multiplexing relationship is configured to indicate that transmission for the at least one media type is performed using a same port number, wherein n is a positive integer, and m is a positive integer smaller than n; and transmitting the negotiation response message to the requesting end.

2 . The method according to claim 1 , wherein in a case that an i-th multiplexing relationship of the m multiplexing relationships corresponds to a plurality of media types of the n media types, multiplexing information on a first media type of the plurality of media types comprises a first port number of the responding end, and multiplexing information on other media types of the plurality of media types except for the first media type comprises a port number 0, to indicate that transmission for the plurality of media types is performed using the first port number of the responding end, wherein i is a positive integer smaller than m.

3 . The method according to claim 2 , wherein information on each media type of the n media types comprises: a port number of the requesting end corresponding to the each media type, which is determined by the requesting end.

4 . The method according to claim 3 , wherein the information on each media type of the information on the n media types comprises at least one of:
at least one encode-decode type supported by the each media type and a payload type (PT) value corresponding to each encode format of the at least one encode-decode type, which are determined by the requesting end; a bandwidth required for transmitting the each media type; interactive connectivity establishment (ICE) candidate address information on the each media type; information indicating that the each media type supports real-time transport protocol (RTP) and real-time transport control protocol (RTCP) multiplexing; and capability information indicating a capability of the requesting end to transmit and receive a media stream of the at least one encode-decode type.

5 . The method according to claim 4 , wherein the capability information comprises a maximum reception number and a maximum transmission number of the requesting end for a media stream of one or more encode-decode types of the at least one encode-decode type.

6 . The method according to claim 2 , wherein the multiplexing information on the first media type further comprises at least one of:
at least one encode-decode type supported by the first media type and a PT value corresponding to each encode-decode type of the at least one encode-decode type, which are determined by the responding end; a sum of bandwidths required by the plurality of media types corresponding to the i-th multiplexing relationship; and a maximum reception number and a maximum transmission number of the responding end for a media stream of one or more encode-decode types of the at least one encode-decode type.

7 . The method according to claim 2 , wherein in a case that a second media type of the n media types does not correspond to any multiplexing relationship of the m multiplexing relationships,
information on the second media type comprises: a second port number of the requesting end corresponding to the second media type; and multiplexing information on the second media type comprises: a second port number of the responding end corresponding to the second media type, which is determined by the responding end.

8 . The method according to claim 2 , wherein, after receiving the negotiation response message transmitted from the responding end, the method further comprises:
transmitting a media stream of the plurality of media types corresponding to the i-th multiplexing relationship using a first port number of the requesting end and the first port number of the responding end; and transmitting a media stream of the second media type using a second port number of the requesting end and a second port number of the responding end.

9 . A requesting end, comprising a processor and a non-transitory computer readable medium having a plurality of computer readable instructions stored thereon that, when executed by the processor, cause the processor to:
transmit a negotiation request message to a responding end, wherein the negotiation request message comprises information on n media types; and receive a negotiation response message transmitted from the responding end, wherein the negotiation response message is configured to indicate m multiplexing relationships, each multiplexing relationship of the m multiplexing relationships corresponds to at least one media type of the n media types and each multiplexing relationship is configured to indicate that transmission for the at least one media type is performed using a same port number, wherein n is a positive integer, and m is a positive integer smaller than n.

10 . The requesting end according to claim 9 , wherein the negotiation response message comprises multiplexing information on the n media types, wherein in a case that an i-th multiplexing relationship of the m multiplexing relationships corresponds to a plurality of media types of the n media types, multiplexing information on a first media type of the plurality of media types comprises a first port number of the responding end, and multiplexing information on other media types of the plurality of media types except for the first media type comprises a port number 0, to indicate that transmission for the plurality of media types is performed using the first port number of the responding end, wherein i is a positive integer smaller than m.

11 . The requesting end according to claim 10 , wherein information on each media type of the n media types comprises: a port number of the requesting end corresponding to the each media type, which is determined by the requesting end.

12 . The requesting end according to claim 10 , wherein the multiplexing information on the first media type further comprises at least one of:
at least one encode-decode type supported by the first media type and a payload type (PT) value corresponding to each encode-decode type of the at least one encode-decode type, which are determined by the responding end; a sum of bandwidths required by the plurality of media types corresponding to the i-th multiplexing relationship; and a maximum reception number and a maximum transmission number of the responding end for a media stream of one or more encode-decode types of the at least one encode-decode type.

13 . The requesting end according to claim 10 , wherein in a case that a second media type of the n media types does not correspond to any multiplexing relationship of the m multiplexing relationships,
information on the second media type comprises: a second port number of the requesting end corresponding to the second media type; and multiplexing information on the second media type comprises: a second port number of the responding end corresponding to the second media type, which is determined by the responding end.

14 . The requesting end according to claim 10 , wherein the computer readable instructions f
