Abstract

The invention provides a dual-mode single-standby wireless voice call continuity method and device before ringing. Wherein, the method includes: the SCC AS receives the bSRVCC switching request from the calling terminal; the SCC AS judges whether the first message carrying the Answer SDP sent by the called terminal is received before receiving the bSRVCC switching request; If the first message is not received before receiving the bSRVCC switching request, the SCC AS buffers the bSRVCC switching request, and terminates the scheduled message sent by the called terminal without the Answer SDP before receiving the first message at the SCC AS . The invention solves the problem that the bSRVCC flow in the relevant 3GPP specifications is not implementable, and provides an implementable bSRVCC flow.

Description

Technical field[0001]The present invention relates to the field of communication, in particular to a method, device and SCC AS for continuity of dual-mode single-standby wireless voice call before ringing.Background technique[0002]Dual-mode single-standby wireless voice call continuity (Single Radio Voice Call Continuity, referred to as SRVCC) is a voice based on IP Multimedia Subsystem (IMS) proposed by the third-generation mobile communications partner (3GPP) The business (VoLTE) continuity solution is mainly to solve the problem of the single radio frequency user equipment (User Equipment, referred to as UE) in the Long Time Evolution (LTE) network and the second generation mobile communication (2G) / first The problem of ensuring the continuity of voice calls when moving between 3G circuit switch (CS) domain networks in three-generation mobile communications. The proposed set of system solutions is the core and key technology of VoLTE technology.[0003]SRVCC before ringing (ie bSRV...
