Embodiment Construction
[0042] The present invention abandons the scheme in which the UE participates in user context synchronization in the existing scheme, but at an appropriate time, one of the mobility management control entities or the Serving GW, the user plane termination point of the UE in an idle state, initiates user context synchronization to another mobility management control entity. Context synchronization process.
[0043] see figure 2 , which is a flow chart of the user context synchronization method provided by the present invention, including:
[0044] S201: The first mobility management control entity and the second mobility management control entity in the EPS system activate the ISR function of the UE, wherein the Serving GW in the EPS system serves as a user plane termination point of the UE in an idle state;
[0045] During the interface release process between the first mobility management control entity and the radio access network, perform the following S202 and S203:
