Kind Code:
A1
Abstract:
The present application relates to the technical field of communications. Disclosed are a method and apparatus for recovering an IMS service. The method comprises: if it is determined that the IMS session of a terminal device is failed, a user data management network node transmits first indication information to a mobility management network node and/or a session management network node, wherein the first indication information is used for indicating that the IMS session of the terminal device is failed, and thus, the mobility management network node and/or the session management network node can re-establish an IMS session for the terminal device, so as to recover an IMS service of the terminal device. According to the solution, by triggering, by means of the user data management network node, the mobility management network node and/or the session management network node to re-establish the IMS session of the terminal device so as to recover the IMS service of the terminal device in a timely mode, the present invention can re-establish the IMS session of the terminal device in a more targeted mode, and effectively reduces the delay of recovering the IMS service.
