Claim 2:
3. The apparatus of claim 2, wherein, when the UE has initiated the Attach procedure or the TAU procedure in an EPS Mobility Management (EMM)-Idle mode, the processor circuitry is configured to perform operations comprising:
controlling deletion of any currently stored UE Radio Capability information of the UE;
not sending any UE Radio Capability information to the base station in the Initial Context Setup Request message or the UE Radio Capability Match Request message such that the base station is to be triggered to request UE Radio Capability information from the UE and to upload the requested UE Radio Capability to the MME in an S1 interface UE Capability Info Indication message;
controlling the network controller circuitry to receive an S1 interface UE Capability Info Indication message from the base station, wherein the S1 interface UE Capability Info Indication message is to include the UE Radio Capability information requested by the base station;
controlling storage of the UE Radio Capability information; and
generating an Initial Context Setup Request message or a UE Radio Capability Match Request message to include the stored UE Radio Capability information in other cases than Attach procedure, Tracking Area Update procedure for the “first TAU following GERAN/UTRAN Attach” and “UE radio capability update” procedure.
