Abstract

The present description relates to a method in which a terminal accesses a base station in a wireless communication system and to a terminal thereof. The method includes broadcasting, to at least one base station, an advertisement message containing identification information for advertising existence of the terminal; receiving, from the base station, an inviting message which allows access to the base station; and performing an access procedure with the base station in accordance with the received inviting message. The present description further relates to a method in which a base station accesses a terminal in a wireless communication system, the method including receiving an advertisement message which is broadcasted by the terminal and contains identification information for advertising existence of the terminal; transmitting, to the terminal, an inviting message which allows access to the base station; and performing an access procedure with the terminal in accordance with the inviting message.

Claims

1. A method of accessing a base station, which is accessed by a mobile station in a wireless communication, comprising the steps of:

broadcasting an advertising message containing an identification information to inform an existence of the mobile station to at least one base station;

receiving an invite message permitting an access to the base station from the base station; and

performing an access procedure with the base station according to the received invite message.

2. The method of claim 1, wherein the advertising message comprises a sleep interval and a listening duration.

3. The method of claim 2, if the invite message is not received for the listening duration, further comprising the step of operating in a sleep mode.

4. The method of claim 1, wherein the advertising message comprises at least one selected from the group consisting of a MAC address of the mobile station, a type of the mobile station, and a service category.

5. The method of claim 1, wherein the invite message comprise at least one selected from the group consisting of an address of the base station, an ID of the base station, a capability, a power constraint, and supported rates.

6. The method of claim 1, wherein the invite message comprises an authentication information containing an authentication algorithm and an authentication key of the mobile station.

7. The method of claim 6, the access procedure performing step, comprising the step of performing an authentication procedure with the base station for an authentication,

wherein the authentication procedure is performed by transmitting an authentication response to the base station based on the invite message containing the authentication information.

8. A mobile station, which accesses a base station in a wireless communication system, comprising:

a radio communication unit configured to tranceive a radio signal with an external; and

a control unit configured to broadcast an advertising message containing an identification information to inform an existence of the mobile station to at least one base station by controlling the radio communication unit, the control unit configured to receive an invite message permitting an access to the base station from the base station, the control unit configured to perform an access procedure with the base station according to the received invite message.

9. The mobile station of claim 8, wherein the advertising message comprises a sleep interval and a listening duration.

10. The mobile station of claim 9, wherein if the invite message is not received for the listening duration, the control unit is configured to control to operate in a sleep mode.

11. The mobile station of claim 8, wherein the advertising message comprises at least one selected from the group consisting of a MAC address of the mobile station, a type of the mobile station, and a service category.

12. The mobile station of claim 8, wherein the invite message comprise at least one selected from the group consisting of an address of the base station, an ID of the base station, a capability, a power constraint, and supported rates.

13. The mobile station of claim 8, wherein the invite message comprises an authentication information containing an authentication algorithm and an authentication key of the mobile station.

14. The mobile station of claim 13, wherein the processor is configured to transmit an authentication response to the base station based on the invite message containing the authentication information by controlling the radio communication unit.

15. A method of accessing a mobile station, which is accessed by a base station in a wireless communication, comprising the steps of:

receiving an advertising message broadcasted by the mobile station and containing identification information to inform an existence of the mobile station;

transmitting an invite message permitting an access to the base station to the mobile station; and

performing an access procedure with the mobile station according to the invite message.

16. The method of claim 15, the invite message transmitting step, comprising the steps of:

judging whether the base station accesses the mobile station based on the advertising message; and

transmitting the invite message to the mobile station according to a result of the judgment.

17. The method of claim 15, wherein the advertising message comprises a MAC address of the mobile station, a type of the mobile station, a service category, a sleep interval, and a listening duration.

18. The method of claim 15, wherein the invite message comprise at least one selected from the group consisting of an address of the base station, an ID of the base station, a capability, a power constraint, and supported rates.

19. The method of claim 15, wherein the invite message comprises an authentication information containing an authentication algorithm and an authentication key of the mobile station.

20. The method of claim 19, the access procedure performing step, comprising the step of performing an authentication procedure with the mobile station for an authentication,

wherein the authentication procedure is performed by receiving an authentication response from the mobile station based on the invite message containing the authentication information.
