Abstract

A plurality of location-based service advertisement messages including location information of base stations belonging to each network are broadcasted with different timing in multiple wireless networks. Therefore, a terminal receives only at least on location-based service advertisement message corresponding to an accessible network among the plurality of location-based service advertisement messages.

Claims

1. A method for broadcasting location information of a base station, the method comprising:

broadcasting a primary location-based service advertisement message including the location information of the base station and timing information for at least one secondary location-based service advertisement message; and

broadcasting a first secondary location-based service advertisement message including location information of at least one base station belonging to a second network other than a first network to which the base station belongs with different timing from the primary location-based service advertisement message, according to the timing information included in the primary location-based service advertisement message,

wherein the timing information included in the primary location-based service advertisement message includes broadcasting time interval information between the primary location-based service advertisement message and the first secondary location-based service advertisement message.

2. The method of claim 1, wherein the primary location-based service advertisement message further includes identification information of the second network.

3. The method of claim 1, further comprising broadcasting a second secondary location-based service advertisement message including location information of at least one base station belonging to a third network other than the second network with different timing from the primary location-based service advertisement message and the first secondary location-based service advertisement message.

4. The method of claim 1, wherein the primary location-based service advertisement message further includes location information of at least one second base station belonging to the first network other than the base station.

5. A method for receiving location information of a base station in a terminal, the method comprising:

receiving a primary location-based service advertisement message including location information of a first base station from the first base station belonging to a first network in which the terminal is positioned and timing information for at least one secondary location-based service advertisement message; and

receiving at least one secondary location-based service advertisement message of a plurality of secondary location-based service advertisement messages that are broadcasted with different timing from the primary location-based service advertisement message from the first base station, according to the timing information included in the primary location-based service advertisement message,

wherein the plurality of secondary location-based service advertisement messages correspond to a plurality of second networks, respectively,

wherein each secondary location-based service advertisement message includes location information of at least one base station belonging to the corresponding second network,

wherein the at least one secondary location-based service advertisement message corresponds to the second network that the terminal can access among the plurality of second networks, and

wherein the timing information included in the primary location-based service advertisement message includes broadcasting time interval information between the primary location-based service advertisement message and a first secondary location-based service advertisement message.

6. The method of claim 5, wherein the timing information included in the primary location-based service advertisement message includes broadcasting time interval information of the plurality of secondary location-based service advertisement messages;

and the plurality of secondary location-based service advertisement messages are broadcasted with different timing in accordance with the broadcasting time interval information.

7. The method of claim 6, wherein the primary location-based service advertisement message further includes identification information of the plurality of second networks.

8. The method of claim 7, wherein the primary location-based service advertisement message further includes information on the number of the plurality of second networks.

9. The method of claim 5, wherein the primary location-based service advertisement message further includes location information of at least one second base station belonging to the first network other than the first base station.

10. A method for broadcasting location information of a base station, the method comprising:

broadcasting a primary location-based service advertisement message including the location information of the base station and timing information for each of a plurality of secondary location-based service advertisement messages; and

broadcasting the plurality of secondary location-based service advertisement messages with different timing after broadcasting the primary location-based service advertisement message according to the timing information included in the primary location-based service advertisement message,

wherein the plurality of secondary location-based service advertisement messages correspond to a plurality of second networks, respectively, other than a first network to which the base station belongs,

wherein each secondary location-based service advertisement message includes location information of at least one base station belonging to the corresponding second network, and

wherein the timing information included in the primary location-based service advertisement message includes broadcasting time interval information between the primary location-based service advertisement message and a first secondary location-based service advertisement message.

11. The method of claim 10, wherein the timing information included in the primary location-based service advertisement message includes broadcasting time interval information of the plurality of secondary location-based service advertisement messages;

and

wherein the plurality of secondary location-based service advertisement messages are broadcasted with different timing in accordance with the broadcasting time interval information.

12. The method of claim 11, wherein the primary location-based service advertisement message further includes identification information of the plurality of second networks.

13. The method of claim 12, wherein the primary location-based service advertisement message further includes information on the number of the plurality of second networks.

14. The method of claim 10, wherein the primary location-based service advertisement message further includes location information of at least one second base station belonging to the first network other than the base station.
