Mobile Device with Improved Service Acquisition with Early MCC Detection

摘要

Apparatuses, systems, and methods for user equipment (UE) devices to determine that it does not have cellular service and perform one or more searches for a mobile country code (MCC). The searches may include searches based on cellular modes, radio access technologies (RATs), and/or cellular bands. The UE may determine the MCC based on results of the one or more searches and perform a targeted service acquisition search based on, and limited by, the MCC. The MCC may be associated with one or more cellular modes, RATs, and/or cellular bands via a data structure that maps the MCC to the one or more cellular modes, RATs, and/or cellular bands. The targeted service acquisition search may include at least one RAT and one or more cellular bands within the at least one RAT associated with the MCC.

主权项

1. A wireless user equipment (UE) device, comprising:
at least one antenna; at least one radio, wherein the at least one radio is configured to perform cellular communication using at least one radio access technology (RAT); one or more processors coupled to the at least one radio, wherein the one or more processors and the at least one radio are configured to perform voice and/or data communications; wherein the UE is configured to:
determine that the UE does not have cellular service;perform one or more searches for a mobile country code (MCC) responsive to said determining the UE does not have cellular service, wherein the one or more searches comprise one or more cellular mode based searches and one or more RAT based searches, wherein to perform the one or more searches, the UE is further configured to perform the one or more cellular mode based searches and the one or more RAT based searches in parallel;determine the MCC based on results of the one or more searches; andperform a targeted service acquisition search according to a cellular mode based on the MCC, wherein the targeted service acquisition search is based on, and limited by, the MCC, and wherein the targeted service acquisition search comprises at least one radio access technology (RAT) searched and one or more cellular bands searched within the at least one RAT.
