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 using an RRC connection message based on a predetermined system information, the method comprising the step of

starting, at the mobile station, the location registration processing on the basis of a Master Information Block (MIB) and a first and a second System Information Block (SIB 1 to SIB 2), when acquiring the MIB and SIB 1 to SIB 2 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 MIB and SIB 1 to SIB 2 comprising information necessary for performing the location registration processing,

wherein the plurality of pieces of system information comprises the MIB, the SIB 1 to SIB 2, and SIBs (System Information Blocks) 3 to 8;

and

wherein SIBs 3 to 8 are pieces of system information which includes information that the mobile station UE needs for performing cell selection or cell reselection.

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.

5. The location registration processing method according to claim 1, wherein the MIB comprises a system frame number (SFN) and physical layer parameters.

7. The location registration processing method according to claim 1, wherein the SIB 1 comprises a PLMN (Public Land Mobile Network)-ID, Tracking Area Code, Cell-ID, cell barring information, and scheduling information on SIBs 2 to 8.

9. The location registration processing method according to claim 1, wherein the SIB 2 comprises access restriction information.

3. A mobile station comprising a location registration processor unit configured to start a location registration processing using an RRC connection message based on a predetermined system information and on the basis of a Master Information Block (MIB) and a first and a second System Information Block (SIB 1 to SIB 2), when acquiring the MIB and SIB 1 to SIB 2 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 MIB and SIB 1 to SIB 2 comprising information necessary for performing the location registration processing,

wherein the plurality of pieces of system information comprises the MIB, the SIB 1 to SIB 2, and SIBs (System Information Blocks) 3 to 8;

and

wherein SIBs 3 to 8 are pieces of system information which includes information that the mobile station UE needs for performing cell selection or cell reselection.

4. The mobile station according to claim 3 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 of claim 3, wherein the MIB comprises a system frame number (SFN) and physical layer parameters.

8. The mobile station of claim 3, wherein the SIB 1 comprises a PLMN (Public Land Mobile Network)-ID, Tracking Area Code, Cell-ID, cell barring information, and scheduling information on SIBs 2 to 8.

10. The mobile station of claim 3, wherein the SIB 2 comprises access restriction information.
