Multi-SIM Acquisition Performance Improvement by Priority Modification in Partial Out-of-Service Conditions

摘要

Various embodiments for improving acquisition of services in multi-SIM mobile devices by using modified priorities for radio access technologies (RATs) in partial out-of-service conditions include determining when a first radio access technology (RAT) within a plurality of RATs begins to use a shared resource within the multi-SIM mobile device that is configured to be utilized by the plurality of RATs, determining whether a second RAT within the plurality of RATs was in-service or out of service at the time when the first RAT began using the shared resource, calculating a modified priority value for the second RAT in response to determining that the second RAT was in-service at the time, and determining an order for subsequent scanning for the services by the plurality of RATs based on the calculated modified priority value for the second RAT when the second RAT in-service at the time.

主权项

1. A method for a multi-SIM mobile device supporting a plurality of radio access technologies (RATs), comprising:
modifying priorities for each of the plurality of RATs that is determined to have been in good channel conditions prior to one of the plurality of RATs beginning to use a shared resource of the multi-SIM mobile device; and determining based on the modified priorities an order in which the plurality of RATs will perform channel scanning to reacquire service when the shared resource becomes available.
