The invention provides a communication self-repairing method and device, and relates to the technical field of
wireless communication. The method comprises the following steps: an S-CSCF
network element receives a periodic re-registration signaling of a terminal for a target service request and records first receiving time; the S-CSCF
network element triggers a re-registration exception in response to that a first duration from the first receiving time to the
current time is greater than or equal to a re-registration
timeout threshold, and confirms IMS subscription information of the terminal and a network attachment state of an evolved
packet core network EPC; and if the IMS subscription information is signed and the network attachment state is online, resetting the IMS registration information and the first receiving time through the ATS
network element so as to recover the response to the target service request. Through the technical scheme provided by the invention, the problems of high
network complexity and low security in related technologies are solved. A third-party
server does not need to be added, and terminal functions do not need to be upgraded, so that the
network complexity is reduced, and the
network security is improved.
