Abstract
The techniques described herein include superior home-on-home roaming procedures by enabling user equipment (UE) to modify a home public land mobile network (HPLMN) search periodicity based on a likelihood of detecting an HPLMN cell (e.g., base station). A UE may be configured to determine a current geographic location of the UE, access a database that includes information about the HPLMN for the location (e.g., prior HPLMN searches), determine an appropriate HPLMN search periodicity based on the information, and perform HPLMN searches based on the appropriate HPLMN search periodicity. In some implementations, the UE may determine the HPLMN search periodicity based on a number (N) of HPLMN cells, and/or times an HPLMN cell sample, associated with the geographic area, has been detected previously.
