Systems and Methods for Managing Different Types of Registrations for IMS Services on SIMs of a Wireless Communication Device

摘要

Methods and devices are disclosed for managing Internet Protocol Multimedia Subsystem (IMS) service registration on a wireless communication device having at least one SIM that supports IMS services. The wireless communication device may access network operator policies stored in the SIM(s), and identify enabled IMS services for each SIM. The wireless communication device may also identify, based on the accessed network operator policies, a registration type for each enabled IMS service on each SIM, determine whether to perform a single registration or a dual IMS registration for each of the at least one SIM, perform the determined registration using the accessed network operator policies, and maintain registration of the enabled IMS services for each SIM.

1. A method of managing Internet Protocol Multimedia Subsystem (IMS) service registrations on a wireless communication device having at least one subscriber identification module (SIM) that supports IMS services, the method comprising:
accessing network operator policies stored in the at least one SIM; identifying enabled IMS services for each of the at least one SIM; identifying a registration type for each enabled IMS service on each of the at least one SIM, wherein the registration type is identified based on the accessed network operator policies; determining whether to perform a single registration or a dual registration for the at least one SIM; performing the determined registration using the accessed network operator policies; and maintaining registration of the enabled IMS services for each of the at least one SIM.
