Method and apparatus for radio access network based notification area update

An apparatus, comprising:

• a receiving circuitry;
• a transmitting circuitry;
• and
• a processor coupled to the receiving circuitry and the transmitting circuitry configured to cause the apparatus to:
• select a first subscriber identity module from a plurality of subscriber identity modules of the apparatus, the plurality of subscriber identity modules are in an inactive state;
• and
• transmit a resume request message via the first subscriber identity module, the resume request message comprises first radio access network RAN)-based notification area (RNA) update information associated with the first subscriber identity module and second RNA update information associated with a second subscriber identity module of the plurality of subscriber identity modules.

An apparatus, comprising:

• a receiving circuitry;
• a transmitting circuitry;
• and
• a processor coupled to the receiving circuitry and the transmitting circuitry configured to cause the apparatus to receive a resume request message from a user equipment (UE), the resume request message comprising first radio access network (RAN)-based notification area (RNA) update information associated with a first subscriber identity module of the UE served by a first base station and second RNA update information associated with a second subscriber identity module of the UE.
