SYSTEM AND METHODS FOR IMPROVING RECOVERY FROM AN OUT OF SERVICE STATE BY SIMS OF A MULTI SIM DEVICE BASED ON USER ACTIVITY

摘要

Methods and devices for controlling recovery from an out of service state on a multi SIM wireless device that has at least two subscription identification modules (SIMs) and that determines whether a voice call or an active data communication session was dropped upon losing service and prioritizes service recovery on the modem stack associated with the dropped voice call or active communication session. If neither a voice or data call was dropped upon losing service on both SIMs the multi SIM wireless device may calculate a priority value for each of the first and second SIMs calculate an RF resource allocation percentage for each of the first and second SIMs and grant use of the RF resource to the modem stacks associated with the first and second SIMs based on the calculated RF resource allocation percentages.
