Abstract

A location registration processing method according to the present invention includes steps of: starting, at a mobile station (UE), the location registration processing on the basis of predetermined system information, when acquiring the predetermined system information among a plurality of pieces of system information broadcasted by a radio base station (eNB), the predetermined system information including information necessary for performing the location registration processing; and acquiring the rest of the plurality of pieces of system information.

Claims

1. A location registration processing method in which a mobile station performs location registration processing, the method comprising the step of:

starting, at the mobile station, the location registration processing on the basis of predetermined system information, when acquiring the predetermined system information among a plurality of pieces of system information broadcasted by a radio base station, and before completing acquiring the rest of the plurality of pieces of system information, the predetermined system information including information necessary for performing the location registration processing.

2. The location registration processing method according to claim 1 comprising the step of:

acquiring the rest of the plurality of pieces of system information after the location registration processing is started.

3. The location registration processing method according to claim 1, wherein

the predetermined system information includes MIB, SIB 1, and SIB 2.

4. A mobile station comprising a location registration processor unit configured to start a location registration processing on the basis of predetermined system information, when acquiring the predetermined system information among a plurality of pieces of system information broadcasted by a radio base station, and before completing acquiring the rest of the plurality of pieces of system information, the predetermined system information including information necessary for performing the location registration processing.

5. The mobile station according to claim 4 comprising an acquiring unit configured to acquire the rest of the plurality of pieces of system information after the location registration processing is started.

6. The mobile station according to claim 4, wherein

the predetermined system information includes MIB, SIB 1, and SIB 2.

7. A location registration processing method in which a mobile station performs location registration processing, the method comprising the step of:

starting, at the mobile station, calling/receiving processing on the basis of predetermined system information, when acquiring the predetermined system information among a plurality of pieces of system information broadcasted by a radio base station, before completing acquiring the rest of the plurality of pieces of system information, and after completing the location registration processing, the predetermined system information including information necessary for performing the location registration processing.

8. A mobile station comprising a calling-receiving processor unit configured to start calling/receiving processing on the basis of predetermined system information, when acquiring the predetermined system information among a plurality of pieces of system information broadcasted by a radio base station, before completing acquiring the rest of the plurality of pieces of system information, and after completing the location registration processing, the predetermined system information including information necessary for performing the location registration processing.
