Method and system for utilizing a single SIM card socket to support multiple SIM cards in a multi-SIM multi-standby communication device

摘要

A multiple-subscriber identity module (multi-SIM) multi-standby communication device comprises a single SIM card socket that handles multiple SIM cards each with a unique SIM clock signal. SIM identification information is acquired from each SIM card utilizing corresponding SIM clock signals. The SIM clock signals may be generated in response to corresponding SIM card selections and are assigned to corresponding SIM cards, respectively. Each of the assigned SIM clock signals is signaled to the single SIM card socket at a different time instant to establish connections between the multi-SIM multi-standby communication device and each of the multiple SIM cards, respectively. SIM identification information is received from each SIM card. The received SIM identification information is stored within the multi-SIM multi-standby communication device for concurrently communication with corresponding communication networks. No device re-booting is performed while activating the stored SIM identification information from one to another of the multiple SIM cards.
