Abstract

Methods and devices are disclosed for enabling efficient network registration using a shared radio resource for at least a first and second SIM of a multi-SIM wireless communication device. An overall priority-based ranking may be calculated for each SIM of the multi-SIM device, which may be used to determine an preferred order for the SIMs to register for services in their respective networks. Calculating the overall priority-based ranking for each SIM may include determining values for a service capability priority factor, an attachment time factor, and a sleep cycle duration factor.
