First Claim
Patent Images
1. A wireless user equipment (UE) device, comprising:
- a radio; and
a processing element operably coupled to the radio,wherein the radio and the processing element are configured to;
initiate a public land mobile network (PLMN) search;
determine one or more mobile country codes (MCCs) corresponding to a current location of the UE;
determine one or more frequencies, frequency bands, or radio access technologies (RATs) associated with the one or more MCCs; and
perform a targeted PLMN search on the determined one or more frequencies, frequency bands, or RATs associated with the one or more MCCs.

Abstract
Targeted public land mobile network (PLMN) search by a wireless user equipment (UE) device. A PLMN search may be initiated at the UE. It may be determined whether PLMN search targeting information is available. A targeted PLMN search may be performed if PLMN search targeting information is available. Targeting the PLMN search may include reducing the number of frequencies or frequency bands searched as part of the PLMN search.

9. A non-transitory computer accessible memory medium comprising program instructions which, when executed at a wireless user equipment (UE) device, cause the UE to:
-
determine a set of radio access technologies (RATs) and frequency bands which the UE is capable of searching for public land mobile networks (PLMNs); determine a location of the UE; determine a set of PLMNs associated with the location; search the set of RATs and frequency bands for the determined set of PLMNs; and abort further search after identifying all PLMNs in the determined set of PLMNs. - View Dependent Claims (10, 11, 12)

13. A method for operating a wireless user equipment (UE) device, the method comprising:
-
initiating a public land mobile network (PLMN) search; determining whether PLMN search targeting information is available; and performing a targeted PLMN search if PLMN search targeting information is available, wherein performing the targeted PLMN search comprises reducing a number of frequencies, frequency bands, and/or radio access technologies (RATs) on which PLMNs are searched for based on the PLMN search targeting information. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
