Abstract

A method of managing a service mode of a femto cell base-station and access allowance for a terminal is disclosed. The method of managing access allowance includes receiving a first access allowance change request for a terminal, and transmitting a second access allowance change request for the terminal to a mobility management entity (MME) in response to the first access allowance change request. With the method of the example embodiments of the present invention, the service mode of the femto base-station and the access allowed terminal can be changed in real time according to a situation of the user. Accordingly, quality of service can be improved and efficient management of the femto base-station can be achieved through interference control between the macro base-station and the femto base-station.

Claims

1. A method of changing a service mode of a femto base-station, the method comprising:

receiving a first service mode change request;

transmitting a second service mode change request to a femto base-station management server in response to the first service mode change request;

receiving an SIB (System Information Block) parameter changed in response to the second service mode change request from the femto base-station management server; and

broadcasting system information generated based on the received SIB parameter.

2. The method according to claim 1, wherein the first service mode change request is received from the terminal through local area communication or from a user via a user interface included in the femto base-station.

3. The method according to claim 1, wherein the first and second service mode change requests are intended to change the service mode of the femto base-station from a closed service group (CSG) service mode to a hybrid service mode or from the hybrid service mode to the closed service group service mode.

4. The method according to claim 1, wherein the changed SIB parameter is a parameter of a field indicating the service mode in the system information.

5. The method according to claim 1, further comprising:

notifying the terminal of service mode change completion through local area communication or notifying a user of the service mode change completion through a user interface.

6. The method according to claim 1, further comprising:

notifying the terminal of a current service mode of the femto base-station through local area communication or notifying a user of the current service mode of the femto base-station via a user interface.

7. A method of managing access allowance for a terminal in a femto base-station, the method comprising:

receiving a first access allowance change request for the terminal; and

transmitting a second access allowance change request for the terminal to a mobility management entity (MME) in response to the first access allowance change request.

8. The method according to claim 7, further comprising:

receiving a result of the second access allowance change request from the mobility management entity; and

notifying of the result of the second access allowance change request.

9. The method according to claim 7, wherein the first access allowance change request is received from the terminal through local area communication or from a user via a user interface included in the femto base-station.

10. The method according to claim 7, wherein the first access allowance change request is a request to change the terminal to a terminal allowed to access the femto base-station or change the terminal to a terminal not allowed to access the femto base-station.

11. The method according to claim 8, comprising:

notifying the terminal of the result of the second access allowance change request through local area communication or notifying a user of the result of the second access allowance change request through a user interface included in the femto base-station.

12. The method according to claim 7, further comprising:

receiving a request for a list of terminals allowed to access the femto base-station from the terminal through local area communication or from a user via a user interface; and

providing the list of access allowed terminals to the terminal through the local area communication or to the user through the user interface.
