Abstract

A method of transmitting network information in a broadband wireless access system is disclosed, in which a base station transmits mobile IP information received from a HA or FA to a mobile station in an idle mode. The present invention includes the steps of receiving a request for entering an idle mode from a mobile station, transmitting information of an admission for entering the idle mode to the mobile station, receiving the network information from a mobility agent, and transmitting a paging message including the network information.

Claims

1. A method of transmitting network information in a broadband wireless access system, the method comprises:

receiving a request for entering an idle mode from a mobile station;

transmitting an admission of the request for entering the idle mode;

receiving the network information from a mobility agent; and

transmitting a paging message including the network information.

2. The method of claim 1, wherein the network information is an agent advertisement message.

3. The method of claim 2, wherein the network information is included in the agent advertisement message by a format of TLV (type length value).

4. The method of claim 3, wherein the agent advertisement message includes mobility agent information corresponding to a location of the mobile station.

5. The method of claim 4, wherein the mobility agent is a home agent (HA) or a foreign agent (FA).

6. The method of claim 5, wherein the request for entering the idle mode is received via a de-registration request message (DREG-REQ).

7. The method of claim 6, wherein the admission for entering the idle mode is transmitted via a de-registration command message (DREG-CMD).

8. The method of claim 7, wherein a value of an action code included in the de-registration command message is 0x05.

9. The method of claim 8, wherein the de-registration command message includes information about a paging cycle and a paging offset.

10. The method of claim 9, further comprises transmitting a paging message including traffic information if a traffic for the mobile station is occurred.

11. The method of claim 1, wherein the mobility agent is used for a mobile IP protocol.

12. A method of transmitting network information in a broadband wireless access system, the method comprises:

receiving network information of location of the base station from a higher layer;

transmitting a paging message (MOB_PAG-ADV) including a timing point of transmitting the network information and a connection identifier (CID) to mobile stations within the base station; and

transmitting the network information via a channel corresponding to the connection identifier at the transmitting timing point.

13. The method of claim 12, wherein the network information is mobility agent information of the location of the base station.

14. The method of claim 13, wherein the paging message is transmitted by broadcast.

15. The method of claim 12, wherein the network information is transmitted by broadcast or multicast.

16. A method of receiving network information in a broadband wireless access system, the method comprises:

transmitting a de-registration request message (DREG-REQ) to a base station for requesting to enter an idle mode;

receiving a de-registration command message (DREG-CMD) from the base station;

entering the idle mode according to the de-registration command message; and

receiving information about a home agent (HA) or a foreign agent (FA) where the mobile station in the idle mode is located.

17. The method of claim 16, wherein the information about the home agent or the foreign agent is received via a paging message (MOB_PAG-ADV).

18. The method of claim 16, further comprising the step of receiving a timing point of transmitting the information about the home agent or the foreign agent and a connection identifier, wherein the information about the home agent or the foreign agent is transmitted via a channel corresponding to the connection identifier at the timing point.

19. The method of claim 18, wherein the transmitting timing point and the information of the connection identifier are received via a paging message (MOB_PAG-ADV).

20. The method of claim 16, wherein the information about the home agent (HA) or the foreign agent (FA) is an agent advertisement message.
