Method for Establishing Connection by Hnb

1. A method for establishing a connection in a network by a base station, the method including: transmitting, by the base station, a first message to a server, the first message including first identification information on the base station and information on a location of the base station, wherein the information on the location of the base station is verified by the server; receiving, by the base station, a second message including information on a mobility management entity (MME) in response to the first message from the server, wherein the MME is assigned based on the first message; and transmitting, by the base station, a third message to the MME based on the information on the MME, the third message including second identification information on the base station, wherein the MME is configured to manage a signaling related to mobility and security, and wherein the first identification information is different than the second identification information.

2. The method according to claim 1 , wherein the first message includes an identifier of a closed subscriber group (CSG) of the base station.

3. The method according to claim 1 , wherein, the MME for the base station is selected by the server based on the first message.

4. The method according to claim 1 , wherein the second message includes information on one of the MME and a serving gateway (S-GW) selected by the server for the base station.

5. The method according to claim 1 , wherein the second message includes information on other base stations adjacent to the base station, the information on other base stations used to establish connections with the other base stations.

6. The method according to claim 5 , wherein the server selects the other base stations adjacent to the base station according to an identifier of a closed subscriber group (CSG) to which the base station belongs.

7. The method according to claim 5 , wherein the server selects the other base stations adjacent to the base station according to a location of the base station.

8. The method according to claim 1 , wherein, a serving gateway (S-GW) for the base station is selected by the server.

9. The method according to claim 1 , wherein, if the base station is a first base station to access the server in a closed subscriber group (CSG) in a certain area, the MME for the base station is selected by the server.

10. The method according to claim 1 , wherein, if the base station is one of a first base station to access the server in a closed subscriber group (CSG) and a first base station to access the network in the CSG in a certain area, one of the MME and a serving gateway (S-GW) is selected by the server according to the location of the base station.

11. The method according to claim 1 , wherein, if the base station is one of a first base station to access the server in a closed subscriber group (CSG) and a first base station to access the network in the CSG in a certain area, one of the MME and a serving gateway (S-GW) is selected by the server according to load balancing.

12. The method according to claim 1 , wherein, if the base station is one of a first base station to access the server in a closed subscriber group (CSG) and a first base station to access the network in the CSG in a certain area, one of the MME and a serving gateway (S-GW) is selected by the server according to a rule of reducing a possibility of changing the one of the MME and the S-GW if a terminal moves.

13. The method according to on claim 1 , wherein, if the base station is not a first base station to access the server in a closed subscriber group (CSG), one of the MME and a serving gateway (S-GW) for the base station is selected by the server that is the same one of the MME and the S-GW selected by the server for other base stations in the CSG.

14. The method according to claim 1 , further including: transmitting a connection setup request message to other base stations based on the second message.

15. The method according to claim 1 , wherein the second message includes information on the MME to which the base station in a closed subscriber group (CSG) connects.

16. The method according to claim 15 , wherein the second message includes an internet protocol (IP) address of the MME.

17. The method according to claim 1 , wherein the second message includes information on a serving gateway (S-GW) to which the base station in a closed subscriber group (CSG) connects.

18. The method according to claim 17 , wherein the information on the S-GW to which the base station in the CSG connects includes an internet protocol (IP) address of the S-GW.

19. The method according to claim 1 , wherein the second message includes information on other base stations in a closed subscriber group (CSG).

20. The method according to claim 19 , wherein the information on other base stations in the CSG includes an internet protocol (IP) address list of the other base stations.

21. The method according to claim 1 , further including: receiving a fourth message from the MME in response to the third message.

22. The method according to claim 21 , wherein the third message includes a track area identifier (TAI) for the base station.

23. The method according to claim 21 , wherein the third message includes information on cells which are overlapped with the base station or a closed subscriber group (CSG).

24. The method according to claim 1 , wherein the information on the MME comprises an internet protocol (IP) address of the MME.

25. A base station in a communication system, the base station including: a transceiver for transmitting and receiving a signal; and a controller configured to transmit a first message including first identification information on the base station and information on a location of the base station to a server, to receive a second message including information on a mobility management entity (MME) assigned based on the first message from the server in response to the first message, and to transmit a third message to the MME based on the information on the MME, the third message including second identification information on the base station, wherein the information on the location of the base station is verified by the server, wherein the first identification information is different than the second identification information, and wherein the MME is configured to manage a signaling related to mobility and security.
