US 9,867,049 B2 · Mobile station performing access control with NAS restriction information sent from radio base station

Abstract

To improve probability of successfully performing origination processing by a priority terminal and origination processing of an emergency call even during congestion. In a mobile station UE according to the present invention, an AS function unit 11 is configured to receive SSAC information from a radio base station eNB and transmit the SSAC information to the NAS function unit 12 at a predetermined timing, and a NAS function unit 12 is configured to perform SSAC on transmission of “RA Preamble” in a RA procedure for the mobile station UE in the DRX state to transmit an uplink signal, or on transmission of an uplink signal from the mobile station UE in the Non-DRX state.

Claims5

Dependent claims

A mobile station comprising a processor and a memory, the memory embodying instructions that cause the processor to function as:

an AS (Access Stratum) function unit;
and
a NAS (Non Access Stratum) function unit, wherein
the AS function unit is configured to receive NAS restriction information from a radio base station, and transmit the NAS restriction information to the NAS function unit, and
the NAS function unit is configured to perform access control processing on transmission of a random access preamble in a random access procedure for the mobile station in a RRC_CONNECTED state and in a Discontinuous Reception (DRX) state to transmit an uplink signal, using the NAS restriction information.
