Enhanced system acquisition while roaming
Abstract:
Various methods, apparatus, and computer readable media are disclosed for enhanced system acquisition while a user equipment (UE) is roaming. The UE may detect roaming from a coverage area associated with a first public land mobile network (PLMN) supporting hybrid voice and data to a coverage area associated with a second PLMN without support for hybrid voice and data. In response to the detection, the UE may store data corresponding to the second PLMN such that the second PLMN is a registered PLMN (RPLMN). The UE may initiate system acquisition, wherein the system acquisition includes searching for the RPLMN prior to searching for any other PLMN. The other PLMN may include a home PLMN (HPLMN). The coverage area associated with the first PLMN may be within a first country, and the coverage area associated with the second network may be within a second country different from the first country.
