UE enhancement for service recovery in mobile communications network
Abstract:
A method of applying a network forbidden list for enhanced service recovery in mobile communication networks is provided. In a first embodiment, upon receiving an error cause for a RAT in a selected network, a UE stores a PLMN ID, the RAT information, and the error cause as an entry in the forbidden list. The UE will not select to the RAT of the network stored in the forbidden list until the PLMN/RAT entry is removed from the forbidden list. In a second embodiment, upon receiving an error cause in a selected network, a UE stores a PLMN ID, the error cause, and a timer value as an entry in the forbidden list. The UE will not select to the network stored in the forbidden list until the timer associated with the PLMN ID is expired.
