Claim 3:
4. The apparatus of claim 2, wherein, when the UE has initiated the TAU procedure in an EMM-Connected mode, the network controller circuitry is configured to perform operations comprising:
receiving a TAU Request message from the UE via NAS signaling, wherein the TAU Request message is to indicate that a UE radio capability information update is needed or that the UE's usage setting changed from the data centric usage setting to the voice centric usage setting or from the voice centric usage setting to the data centric usage setting;
transmitting a UE Radio Capability Match Request message to the base station via S1 signaling, wherein the UE Radio Capability Match Request message is to include an update needed indicator, wherein the update needed indicator is to trigger the base station to send a UE Capability Enquiry message to the UE via radio resource control (RRC) signaling; and
receiving a UE Capability Info Indication message via the S1 signaling, wherein the UE Capability Info message is to include a UE Radio Capability information element (IE) and wherein the UE Radio Capability IE is to include a CE mode B support indication, and
wherein the processor circuitry is configured to control storage of information of the UE Radio Capability IE in association with an identifier of the UE for subsequent network accesses by the UE.
