Abstract: Methods, devices, and systems embodiments enable recovering from an out-of-service state in a wireless device. A processor may perform scans of first and second acquisition databases to acquire a first renewed service connection for a first subscriber identification module (SIM). The scans include first and second searches for first channels identified in first and second technology lists, respectively, from the first and second acquisition database, respectively, until either a renewed service connection is acquired or each of the first and second technology lists are exhausted. The first and second technology lists identify channels from a most recently used radio access technology of the respective acquisition databases. The processor may perform a full frequency scan to acquire a first renewed service connection for the first SIM in response to determining that each of the first and second technology lists were exhausted.

Abstract: In various aspects, the disclosure provides the capability for a UE to implement a partial PLMN scan, providing quick results to a user's request for a manual PLMN scan, in a way that is expedited relative to the conventional method of providing PLMN results only when a full scan is completed. In further aspects, the disclosure provides for various optimizations to expedite a PLMN scan, which may be implemented either with the partial PLMN scan, or in a full PLMN scan, to further expedite the provision of PLMN scan results to the user.
