Abstract:
Systems and methods are presented to support operation of a multiple subscriber identity module (SIM) device. A first SIM may perform a data transfer or voice call. During the first SIM's data transfer or voice call, transition times are identified to transition communication resources to a second SIM for use in performing a registration update communication with a network controller that supports the second SIM. The registration update communication may include a periodic location update, a periodic routing update, or a periodic tracking update. The multiple SIM device may identify the transition time by obtaining periodic registration timing information from the network controller, configuring a periodic registration timer based on the periodic registration timing information, and setting the transition time as an expiration time of the periodic registration timer.
