Abstract

A method for managing hot cell devices includes receiving at least one of location information of at least one hot cell device, type information of at least one hot cell, location information of at least one terminal and uplink signal energy of at least one terminal measured by a hot cell device. The method also includes determining a hot cell device to be opened using the at least one of the location information of at least one hot cell device, the type information of at least one hot cell, the location information of at least one terminal and the uplink signal energy of at least one terminal. In addition, the method includes transmitting a message instructing the hot cell device to open.

Claims

1. A method for managing a plurality of base stations, the method comprises:

receiving type information of the plurality of base stations and information on uplink signal energy of at least one terminal determined by the plurality of base stations;

identifying a base station among the plurality of base stations based on the type information of the plurality of base stations and the information on uplink signal energy of the at least one terminal, wherein the base station is in a closed state providing no access service to terminals; and

transmitting a message for transitioning the base station from the closed state to an open state to provide the access service to the terminals,

wherein respective type information of respective base station among the plurality of base stations is related to a size of coverage of the respective base station.

2. The method of claim 1, wherein the message comprises information indicating an amount of load to be processed to be covered by the base station.

3. The method of claim 1, wherein the type information of the base station is received from the base station when the base station is transitioning from the open state to the closed state.

4. The method of claim 1, wherein the type information of the plurality of base stations is received through a second message for X2 interface establishment.

5. The method of claim 1, wherein the type information of the plurality of base stations is received via mobility management entity (MME).

23. The method of claim 1, wherein the type information indicates a coverage size, a grade of the coverage size, or a cell type name.

6. A method for an operation of a base station, the method comprises:

transmitting type information of the base station, and information on uplink signal energy of at least one terminal determined by the base station;

receiving a message for transitioning the base station from a closed state to an open state to provide an access service to terminals, wherein the message is received in the closed state where the base station provides no access service to terminals; and

providing the access service to the terminals by transitioning the base station from the closed state to the open state,

wherein the base station is identified from among a plurality of base stations based on the type information of the base station and the information on the uplink signal energy,

wherein the type information of the base station is related to a size of coverage of the base station.

7. The method of claim 6, wherein the message comprises information indicating an amount of load to be processed by the base station.

8. The method of claim 7, further comprising:

determining whether to activate the base station partly or completely based on a capability of the base station and the amount of the load to be processed indicated by the message.

9. The method of claim 6, wherein the type information of the base station is transmitted when the base station is transitioning from the open state to the closed state.

10. The method of claim 6, wherein the type information of the base station is transmitted through a second message for X2 interface establishment.

11. The method of claim 6, wherein the type information of the base station is transmitted via mobility management entity (MME).

24. The method of claim 6, wherein the type information indicates a coverage size, a grade of the coverage size, or a cell type name.

12. An apparatus for managing a plurality of base stations, the apparatus comprises:

a communication unit configured to receive type information of the plurality of base stations and information on uplink signal energy of at least one terminal determined by the plurality of base stations; and

a controller configured to identify a base station among the plurality of base stations based on the type information of the plurality of base stations and the information on uplink signal energy of the at least one terminal, and to control to transmit a message for transitioning the base station from a closed state to an open state to provide an access service to terminals,

wherein the base station is in the closed state where the base station provides no access service to the terminals,

wherein respective type information of respective base station among the plurality of base stations is related to a size of coverage of the respective base station.

13. The apparatus of claim 12, wherein the message comprises information indicating an amount of load to be processed by the base station.

14. The apparatus of claim 12, wherein the type information of the base station is received from the base station when the base station is transitioning from the open state to the closed state.

15. The apparatus of claim 12, wherein the type information of the plurality of base stations is received through a second message for X2 interface establishment.

16. The apparatus of claim 12, wherein the type information of the plurality of base stations is received via mobility management entity (MME).

25. The apparatus of claim 12, wherein the type information indicates a coverage size, a grade of the coverage size, or a cell type name.

17. An apparatus for a base station, the apparatus comprises:

a communication unit configured to transmit type information of the base station and information on uplink signal energy of at least one terminal determined by the base station, and to receive a message for transitioning the base station from a closed state to an open state to provide an access service to terminals; and

a controller configured to provide the access service to the terminals by transitioning the base station from the closed state to the open state,

wherein the message is received in the closed state where the base station provides no access to the terminals,

wherein the base station is identified from among a plurality of base stations based on the type information of the base station and the information on the uplink signal energy, and

wherein the type information of the base station is related to a size of coverage of the base station.

18. The apparatus of claim 17, wherein the message comprises information indicating an amount of load to be processed by the base station.

19. The apparatus of claim 18, wherein the controller is configured to determine whether activating the base station partly or completely based on a capability of the base station and the amount of load to be processed indicated by the message.

20. The apparatus of claim 17, wherein the type information of the base station is transmitted from the base station when the base station is transitioning from the open state to the closed state.

21. The apparatus of claim 17, wherein the type information of the base station is transmitted through a second message for X2 interface establishment.
