A method for preventing a ue from entering into a permanent out of service state

摘要

Embodiments herein provide a User Equipment (UE) configured for preventing the UE from entering into a permanent Out of Service (OOS) state. The UE comprises a processor and a memory for storing computer-executable instructions that configure the processor to receive a registration reject message associated with a permanent cause when the UE triggers a registration request for registering onto a first network entity. The processor is configured to detect whether the UE is previously registered onto at least one second network entity in response to receiving the registration reject message associated with the permanent cause. The processor is configured to store a network entity identifier of the first network entity in a temporary forbidden list in response to detecting that the UE is previously registered onto at least one second network entity to prevent said UE from entering into the permanent OOS state.
