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 paging message at a base station belonged to at least one paging group, the method comprising steps of:

allocating a paging group offset (PGO) for each of the at least one paging group;

transmitting a message including at least one of the paging group offset (PGO); and

transmitting the paging message for the paging group corresponding to the at least one paging group offset at a timing point indicated by the at least one paging group offset.

2. The method of claim 1, wherein the message is a deregistration command (DREG-CMD) message and wherein the deregistration command message further includes a paging cycle parameter and a paging listening interval parameter.

3. The method of claim 2, further comprising the step of receiving a deregistration request message for requesting an entry into an idle mode from a mobile station.

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

5. A method of transmitting paging message at a base station belonged at least one paging group, the method comprising steps of:

allocating a paging group offset (PGO) per a prescribed number of paging groups in the at least one paging group;

transmitting a message including at least one of the paging group offset (PGO); and

transmitting the paging message for the paging group corresponding to the at least one paging group offset at a timing point indicated by the at least one paging group offset.

6. The method of claim 5, further comprising the step of receiving a deregistration request message for requesting an entry into an idle mode from a mobile station.

7. The method of claim 6, wherein the message is a deregistration command message and wherein the deregistration command message further includes a paging cycle parameter and a paging listening interval parameter.

8. The method of claim 7, wherein one of the at least one paging groups is a primary paging group and wherein the rest of the at least one paging groups are secondary paging groups.

9. A method of receiving paging message at a mobile station from a base station belonged to at least one of paging group, comprising the steps of:

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 at least one paging group offset (PGO) for the at least one paging group; and

receiving a paging message for the at least one paging group at a timing point indicated by the at least one paging group offset (PGO),

wherein the at least one paging group offset (PGO) is allocated per at least one of the at least one paging groups.

10. The method of claim 9, wherein the mobile station belongs to one or more of the at least one paging group.

11. The method of claim 10, wherein the deregistration command message includes an identifier for the at least one paging group, a paging cycle parameter and a paging listening interval parameter.

12. A base station, which supports a paging operation for a mobile station in an idle mode, the base station comprising:

a transmitting module controlling transmissions of messages used in the idle mode;

a receiving module controlling receptions of the messages used in the idle mode;

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 allocates a paging group offset (PGO) for each of at least one paging groups to which the base station belongs,

wherein the processor controls a transmission of a message including the at least one paging group offset (PGO) to the mobile station using the transmitting module, and

a transmission of a paging message for the paging group corresponding to the at least one paging group to the mobile station at a timing point indicated by the at least one paging group offset using the transmitting module.

13. The base station of claim 12, wherein the receiving module receives a deregistration request (DREG-REQ) message for requesting an entry into the idle mode from the mobile station.

14. The base station of claim 13, wherein the message is a deregistration command (DREG-CMD) message and wherein the deregistration command (DREG-CMD) message further includes a paging cycle parameter and a paging listening interval parameter.

15. The base station of claim 12, wherein parts of the at least one paging group are primary paging groups and the rest of the at least one paging group are secondary paging groups.

16. A mobile station, which receives a paging message in an idle mode from a base station belonging to at least one or more paging groups, the mobile station comprising:

a transmitting module controlling transmissions of messages used in the idle mode;

a receiving module controlling receptions of the messages used in the idle mode;

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 transmits a deregistration request message for requesting an idle mode entry to the base station using the transmitting module,

wherein the receiving module receives a deregistration command message including at least one paging group offset (PGO) for the at least one paging group and then delivers the received deregistration command message to the processor,

wherein the processor receives the paging message for the paging group at a timing point indicated by the at least one paging group offset (PGO) using the receiving module, and

wherein the at least one paging group offset (PGO) is allocated per one or more of the at least one paging group.

17. The mobile station of claim 16, wherein the deregistration command message further includes a paging cycle parameter and a paging listening interval parameter.

18. The mobile station of claim 16, wherein parts of the at least one paging groups are primary paging groups and the rest of the at least one paging groups are secondary paging groups.
