Embodiment 1

[0047] Such as figure 1 As shown, the media codec negotiation method in Embodiment 1 of the present invention includes:

[0048] Step 11, the first terminal device sends a request signaling to at least one second terminal device;

[0049] Wherein, the request signaling includes request information for obtaining the media codec capability set supported by the second terminal device;

[0050] It should be noted that the request signaling is a signaling for communication between terminal devices, which is an existing signaling. For example, the request signaling can be an INVITE signaling, and the INVITE signaling carries a query header, and the query The header is used to inform the second terminal device that it needs to obtain the media codec capability set it supports, and the query header is the above request information.

[0051] Step 12, the first terminal device receives at least one response signaling sent by the second terminal device according to the request informat...

Embodiment 2

[0115] Such as Figure 4 As shown, corresponding to the media codec negotiation method in Embodiment 1, Embodiment 2 of the present invention provides a first terminal device, including:

[0116] The first sending module 41 is configured to send request signaling to at least one second terminal device, where the request signaling includes request information for obtaining a media codec capability set supported by the second terminal device;

[0117] The first receiving module 42 is configured to receive at least one response signaling sent by the second terminal device according to the request information, where the response signaling includes the media codec capability set supported by the second terminal device;

[0118] A negotiation module 43, configured to negotiate with at least one second terminal device to obtain a first media codec according to the media codec capability set supported by at least one second terminal device;

[0119] The processing module 44 is config...

Embodiment 3

[0127] Such as Figure 5 As shown, the media codec negotiation method in Embodiment 3 of the present invention is applied to the second terminal device, including:

[0128] Step 51, receiving the request signaling sent by the first terminal device;

[0129] Wherein, the request signaling includes request information for acquiring the media codec capability set of the second terminal device;

[0130] Step 52, sending a response signaling to the first terminal device according to the request information;

[0131] Wherein, the response signaling includes the media codec capability set supported by the second terminal device.

[0132] Specifically, the implementation of step 52 is:

[0133] The response signaling is sent to the first terminal device through the IP Multimedia Subsystem IMS.

[0134] Optionally, the response signaling is session initiation protocol signaling or session description protocol signaling.

[0135] It should be noted that all the descriptions about t...

Abstract

The invention provides a media coding-decoding negotiation method and a terminal device. The media coding-decoding negotiation method applied to a first terminal device comprises: the first terminal device sends a request signaling to at least one second terminal device, wherein the request signaling includes obtaining request information of a media coding-decoding capability set supported by the second terminal device; the first terminal device receives a response signaling sent by the at least one second terminal device based on the request information, wherein the response signaling includes the a media coding-decoding capability set supported by the second terminal device; according to the media coding-decoding capability set supported by the at least one second terminal device, negotiation with the at least one second terminal device is carried out to obtain first media coding-decoding information; and sound mixing is carried out based on the first media coding-decoding information and an audio signal of the at least one second terminal device. Therefore, the success rate of media coding-decoding negotiation is increased; and the sound mixing quality of the terminal device can be guaranteed in terms of multi-side sound mixing.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a media codec negotiation method and terminal equipment. Background technique [0002] In an IMS (IP Multimedia Subsystem, IP Multimedia Subsystem) network, when communicating devices need to negotiate media codec capabilities, the following methods are usually used: [0003] Method 1. Device A sends its own media codec capability to device B communicating with it, and then device B determines the media codec used by the two according to the media codec capability set of device A, and sends the media codec to the device A; [0004] The problem with this method is: when another device C connected to device A wants to achieve three-party audio mixing with device B, because device A cannot completely obtain the media codec capability set of device B and device C, it will cause Although device B and device C have a common media codec intersection, but because the media codec...
