Abstract

Various methods of transmitting paging information in a wireless access system are disclosed. A method of transmitting paging information from a base station belonging to at least one paging groups according to one embodiment of the present invention includes the steps of allocating a paging group offset (PGO) per one specific one of at least one paging groups, transmitting a message including one paging group offset (PGO) per one specific paging group, and transmitting a broadcast channel (BCH) including paging group formation on the specific paging group at a timing point indicated by the paging group offset.

Claims

1. A method of transmitting a broadcast channel (BCH) message at a base station (BS) belonging to a plurality of paging groups, the method comprising:

allocating a plurality of paging group offsets (PGOs) by a superframe length unit for each of the plurality of paging groups;

transmitting a deregistration command (DREG-CMD) message including a paging offset and at least one of the plurality of PGOs, wherein the paging offset indicates a frame where a paging listening interval starts during a paging cycle, and the at least one of the plurality of PGOs indicates a superframe where the BCH message is transmitted; and

transmitting the BCH message including paging group information at the superframe indicated by the at least one of the plurality of PGOs,

wherein the DREG-CMD message further includes a paging cycle parameter related to the paging cycle and a paging listening interval parameter related to the paging listening interval.

2. The method of claim 1, further comprising:

receiving a deregistration request message for requesting an entry into an idle mode from a mobile station.

3. The method of claim 1, wherein one of the plurality of paging groups is a primary paging group, and the rest of the plurality of paging groups are secondary paging groups.

4. A method of receiving a broadcast channel (BCH) message at a mobile station from a base station belonging to a plurality of paging groups, the method comprising:

transmitting a deregistration request (DREG-REQ) message for requesting an idle mode entry to the base station;

receiving a deregistration command (DREG-CMD) message including a paging offset and at least one of a plurality of paging group offsets (PGOs) allocated by a superframe length unit for the plurality of paging groups, wherein the paging offset indicates a frame where a paging listening interval starts during a paging cycle, and the at least one of the plurality of PGOs indicates a superframe where the BCH message is transmitted; and

receiving the BCH message including paging group information at the superframe indicated by the at least one of the plurality of PGOs,

wherein;

the plurality of PGOs are allocated per the plurality of paging groups; and

the DREG-CMD message further includes a paging cycle parameter related to the paging cycle and a paging listening interval parameter related to the paging listening interval.

5. The method of claim 4, wherein the mobile station belongs to one or more of the plurality of paging groups.

6. A base station supporting a paging operation for a mobile station in an idle mode, the base station comprising:

a transmitting module;

a receiving module;

a memory storing a parameter and information element used in the idle mode; and

a processor supporting the paging operation of the idle mode,

wherein;

the processor allocates a plurality of paging group offsets (PGOs) by a superframe length unit for each of a plurality of paging groups to which the base station belongs;

the processor controls a transmission of a deregistration command (DREG-CMD) message including a paging offset and at least one of the plurality of the PGOs to the mobile station using the transmitting module;

the paging offset indicates a frame where a paging listening interval starts during a paging cycle, and the at least one of the plurality of PGOs indicates a superframe where a broadcast channel (BCH) message is transmitted;

the processor controls a transmission of the BCH message including paging group information at the superframe indicated by the at least one of the plurality of the PGOs; and

the DREG-CMD message further includes a paging cycle parameter related to the paging cycle and a paging listening interval parameter related to the paging listening interval.

7. The base station of claim 6, wherein the receiving module receives a deregistration request (DREG-REQ) message for requesting an entry into the idle mode from the mobile station.

8. The base station of claim 6, wherein one of the plurality of paging groups is a primary paging group, and the rest of the plurality of paging groups are secondary paging groups.

9. A mobile station for receiving a broadcast channel (BCH) message in an idle mode from a base station belonging to a plurality of paging groups, the mobile station comprising:

a transmitting module;

a receiving module;

a memory storing a parameter and information element used in the idle mode; and

a processor controlling an operation of the idle mode,

wherein;

the processor controls the transmitting module to transmit a deregistration request message for requesting an idle mode entry to the base station;

the receiving module receives a deregistration command message including a paging offset and at least one of a plurality of paging group offsets (PGOs) allocated by a superframe length unit for the plurality of paging groups and then delivers the received deregistration command message to the processor;

the paging offset indicates a frame where a paging listening interval starts during a paging cycle, and the at least one of the plurality of PGOs indicates a superframe where a broadcast channel (BCH) message is transmitted;

the processor controls the receiving module to receive the BCH message including paging group information at the superframe indicated by the at least one of the plurality of PGOs;

the at least one of the plurality of PGOs is allocated per one or more of the plurality of paging groups; and

the deregistration command message further includes a paging cycle parameter related to the paging cycle and a paging listening interval parameter related to the paging listening interval.

10. The mobile station of claim 9, wherein one of the plurality of paging groups is a primary paging group, and the rest of the plurality of paging groups are secondary paging groups.
