Abstract

Apparatuses, methods, and systems are disclosed for paging multi-SIM devices in the same network. One apparatus includes a first subscriber identity module (“SIM”), a second SIM, a processor and a transceiver that communicates with at least one communication network. The processor registers with a first communication network using the first SIM and registers with a second communication network using the second SIM. Here, the registration with the first communication network is associated with a first identifier, wherein registering with the second communication network includes indicating the first identifier to the second communication network upon determining that the first communication network and the second communication network are the same communication network.

Claims20

Dependent claims

An apparatus comprising:

at least one memory;
and
at least one processor coupled with the at least one memory and configured to cause the apparatus to:
receive a registration request initiating a first registration to register a user equipment (“UE”) with a communication network using a first subscriber identity module (“SIM”) of the UE;
determine that the UE is registered with the communication network via a second registration using a second SIM in of the UE;
identify a mobility management (“MM”) function serving the second registration;
determine whether the MM function is able to serve the first registration;
initiate a relocation to transfer the first registration to the MM function in response to determining that the MM function is able to serve the first registration;
and
update an MM context in the MM function corresponding to the second registration to contain an identifier of the first registration, in response to determining that the MM function is unable to serve the first registration.
