Abstract

A method and system of operating a multiple Subscriber Identity Module (SIM) mobile device is provided. The method includes determining, when the multi-SIM mobile device triggers a public land mobile network (PLMN) search, between a first registered public land mobile network (RPLMN) of a first SIM of the multi-SIM mobile device and a second RPLMN of a second SIM. Whether at least one of the RPLMNs is unavailable for the multi-SIM mobile device; in response to determining that at least one of the first RPLMN and the second RPLMN is unavailable, from the first set of PLMNs associated with the first SIM and with the second SIM The associated second set of PLMNs identifies a common PLMN; and camping on the common PLMN by the first SIM and the second SIM after obtaining camping information for the common PLMN.

Description

technical field [0001] This disclosure relates to telecommunications. More specifically, the present disclosure relates to optimizing power consumption of multiple Subscriber Identity Module (SIM) mobile devices. Background technique [0002] The multi-subscriber identity module (SIM) mobile device market is primarily driven by users who consciously desire to switch between service providers to take advantage of the best deals. Business and professional users appreciate the ability of multi-SIM mobile devices to enable them to have separate mobile numbers for personal and business calls. Currently, most multi-SIM mobile devices generally support dual-SIM functionality. However, multi-SIM mobile devices supporting more than two SIM cards are currently being launched in the mobile market. Various types of multi-SIM mobile devices are currently available in the market, such as Dual SIM Single Standby (DSSS), Dual SIM Dual Standby (DSDS) and Dual SIM Dual Access (DSDA). A DS...
