METHOD AND DEVICE FOR PREVENTING LOSS OF NETWORK SECURITY SYNCHRONIZATION

摘要

A method and a device for avoiding network security desynchronization are provided. The method includes: processing only security parameter in a user terminal (a Universal Subscriber Identity Module (USIM) part) at an appropriate time, or processing security parameter in both the user terminal (a Mobile Equipment (ME) part) and the network when a network handover of the user terminal is performed. By modifying a security parameter at an appropriate time, the failure of a UE to access a network due to the security parameter desynchronization is effectively avoided, and network availability and security in handover-related scenarios are improved.
