Abstract:
A User Equipment (UE) device and associated method for operating a User Equipment (UE) in a wireless communication system. The UE may store a preferred roaming list in a memory. The preferred roaming list may comprise a plurality of system records which specify radio access technologies that can be used by the UE. The UE may examine the preferred roaming list to delete any duplicate system records in the PRL for respective geographic locations (GEOs). This may operate to mitigate the problems created by duplicate listing of system records within the PRL. In particular, the removal of redundant system records within the PRL may reduce or eliminate unneeded or undesired BSR algorithm execution. In addition, the removal of redundant system records within the PRL may reduce temporal service outages, since no service origination is allowed while the UE is attempting to find the most preferred system.
