1. A core network node for mobility management, comprising:
a memory storing instructions; and
one or more processors configured to execute the instructions to:
receive, in a registration procedure, from a user equipment (UE), a first message comprising a first parameter related to a Multi-Subscriber Identity Module (Multi-SIM) capability of the UE, wherein the first parameter is different from a UE identity (ID) related parameter and is based on the UE activating Multi-SIM;
after receipt of the first message, transmit, to the UE, a second message comprising a second parameter related to the Multi-SIM capability of the UE; and
receive, from the UE, a third message comprising a third parameter related to the Multi-SIM capability of the UE, wherein the third parameter is different from the UE ID related parameter, the third parameter has a value different from a value of the first parameter, and the third parameter is based on the UE activating a Single-SIM.
