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...
