Abstract
Apparatus and methods are disclosed for reducing or eliminating searches by a UE for its home PLMN when the mobile station is roaming in a network not in the vicinity of the home PLMN. That is, the UE may be provisioned with information about its home PLMN. For example, some embodiments can comprise a neighbor database indicating neighbor relationships between PLMNs and the home PLMN. This can enable a UE to determine whether the home PLMN is likely to be nearby when it is visiting a different PLMN. Forgoing a PLMN home search reduces processing and can aid in conserving power resources. Other aspects, embodiments, and features are also claimed and described.
