Problems solved by technology

Under normal circumstances, the new MME constructs a DNS query based on the GUTI value, finds the old MME, and completes the TAU process; under abnormal circumstances, the old MME fails, and the new MME still sends request information to the old MME, and the request response times out, resulting in TAU failure directly leads to interruption of VoLTE services

Abstract

Embodiments of the present invention provide a communication link connection method, device, equipment and medium. Wherein, the method includes: when the terminal moves from the source MME of the first mobility management entity MME pool to the target MME of the second MME pool, querying the first backup MME in the first MME pool; querying the first backup MME of the source MME through the first backup MME Two backup MME; connect to the source MME through the second backup MME. The technical solution of the present invention can solve the problem in the prior art that TAU ​​cannot be implemented when the source MME fails.

Description

Communication link connection method, device, equipment and medium technical field The present invention relates to the field of communication technologies, and in particular, to a method, apparatus, device and medium for connecting a communication link Background technique VoLTE (Voice over Long Term Evolution) solution is the ultimate solution of voice service In this case, with the increasing maturity of VoLTE technology, users have put forward higher requirements for network availability and reliability. Voice over VoLTE The communication involves EPC (Evolved Packet Core) core network and IMS (IP Multimedia Subsystem) core network, EPC serves as the access side of IMS services. The failure of each network element will affect the call quality and continuity of VoLTE services. influences. In order to provide effective network quality assurance, stricter requirements must be put forward for the disaster tolerance of the EPC side link. The full name of MME is Mo...
