Problems solved by technology

At the same time, since VoLTE terminals support far more codec types than traditional network terminals, the description content of media information in signaling messages is too long, which is difficult for traditional networks to handle.

Embodiment Construction

[0029] The technical solution of the present disclosure will be described in further detail below with reference to the drawings and embodiments.

[0030] The flowchart of an embodiment of the media negotiation method of the present disclosure is as follows figure 1 shown.

[0031] In step 101, the media gateway control device receives a call request from a calling network. The calling terminal may be a VoLTE network terminal. In one embodiment, the call request includes the coding type supported by the calling terminal, and the media gateway control device may be an MGCF network element.

[0032] In step 102, the coding type supported by the calling terminal carried in the call request is replaced with the coding type supported by the called network where the called terminal is located, and the call request is forwarded to the called terminal. In an embodiment, a codec conversion module may be added to an IWU (Interworking Unit, Interworking Unit) of the MGCF network eleme...

Abstract

The disclosure provides a media negotiation method, a media gateway control device and a computer-readable storage medium, and relates to the technical field of mobile communication. A media negotiation method of the present disclosure includes: the media gateway control device receives a call request from the calling network; replaces the coding type supported by the calling terminal carried in the calling request with the coding type supported by the called network; receives the call request from the called network. The call response of the terminal; in the case that the code type included in the call response does not overlap with the code type supported by the calling terminal, code conversion is performed on the call service. Such a method can avoid carrying media description information that cannot be supported by the network in the message, shorten the length of the signaling message, and realize media negotiation for cross-network communication of VoLTE terminals.

Description

technical field [0001] The present disclosure relates to the technical field of mobile communication, in particular to a media negotiation method, a media gateway control device and a computer-readable storage medium. Background technique [0002] During the communication process, the two communicating parties need to determine the codecs supported by both parties through media negotiation, and then establish a call. In the existing technology, codec conversion is often performed through a MGCF (Media Gateway Control Function, media gateway control function) network element. [0003] Since the high-definition audio and video codec types of VoLTE (Voice over LTE, voice service based on IP multimedia subsystem) terminals are different from those of traditional network terminals, MGCF only simply compares the VoLTE terminals and the media types they support during the media negotiation process. Superimposed, and then sent to the traditional network. At the same time, since Vo...
