Abstract

A method, device and storage medium for media session processing, the method comprising: if the service application server receives the first switching request message from the calling session management function network element before receiving the first 200 OK response from the called terminal, Then it is determined that the media negotiation between the calling terminal and the called terminal has not been completed, the first 200 OK response refers to the response confirmation response of the called terminal to the media negotiation request initiated by the calling terminal, and the first handover request message is used to indicate that the calling terminal A network handover occurs; a temporary response is generated according to the first SDP information body in the first handover request message, and sent to the calling session control function network element, and the temporary response is used for network switching of the calling terminal; from the calling session control function network element A first provisional response confirmation message for instructing the calling terminal to complete the network switching is received. By adopting this solution, the network switching of the calling terminal before the media negotiation between the calling terminal and the called terminal is completed can be realized.

Description

technical field [0001] The present application relates to the technical field of IMS, and in particular to a method, device and storage medium for media session processing. Background technique [0002] During a media session based on a long term evolution (voice over long term evolution, VoLTE) network user, if the user moves out of the long term evolution (long term evolution, LTE) network, the user can continue through the single radio voice call continuity, SRVCC) is switched to the 2G / 3G network, so as to ensure the continuity of the media session between the terminals. During the establishment of an Internet Protocol Multimedia System (internet protocol Multimedia Subsystem, IMS) session, the terminal (including the calling terminal and the called terminal) performs session initiation protocol (session initiation protocol, SIP) signaling interaction with the IMS, through the session description protocol ( session description protocol (SDP) information for media negoti...
