Abstract

A radio communication system includes a relay apparatus (30) connected between a base station (40) and a base control station (20) and a location information control station (10), in which: the location information control station (10) includes: a request generation unit (11) for generating a location information request including regional information of a region for which the location information is requested; and a request transmission unit (12) for transmitting the location information request that has been generated to the base control station (20), and the base control station (20) includes: a request reception unit (21) for receiving the location information request transmitted from the location information control station (10); and a request transmission unit (22) for transmitting the location information request including the regional information in the location information request that has been received to the relay apparatus (30). It is therefore possible to accurately transmit the location information request.

Claims

1. A radio communication system comprising a relay apparatus connected between a base station and a base control station and a location information control station that manages location information of the base station, wherein:

the location information control station comprises;

a request generation unit that generates a location information request including regional information of a region for which the location information is requested; and

a request transmission unit that transmits the location information request that has been generated to the base control station, and

the base control station comprises;

a request reception unit that receives the location information request transmitted from the location information control station; and

a request transmission unit that transmits the location information request including the regional information in the location information request that has been received to the relay apparatus.

2. The radio communication system according to claim 1, wherein the request transmission unit of the base control station transmits the location information request to one or more base stations or the relay apparatus connected to the base station corresponding to the regional information.

3. The radio communication system according to claim 1, wherein the relay apparatus comprises:

a request reception unit that receives the location information request transmitted from the base control station; and

a request transmission unit that transmits the location information request to one or more base stations corresponding to the regional information in the location information request that has been received.

4. The radio communication system according to claim 2, wherein the base control station comprises:

a response reception unit that receives a location information response from one or more base stations or the relay apparatus connected to the base station; and

a response transmission unit that aggregates the location information responses that have been received and transmits the aggregated responses to the location information control station.

5. The radio communication system according to claim 3, wherein the relay apparatus comprises:

a response reception unit that receives a location information response from the one or more base stations; and

a response transmission unit that aggregates the location information responses that have been received and transmits the aggregated responses to the base control station.

6. The radio communication system according to claim 4, wherein, when there are a plurality of location information responses to be transmitted, sub-process numbers indicating that the plurality of location information responses are aggregated in one process are provided to process numbers included the plurality of location information responses.

7. A radio communication method in a radio communication system comprising a relay apparatus connected between a base station and a base control station and a location information control station that manages location information of the base station, wherein:

the location information control station generates a location information request including regional information of a region for which the location information is requested,

the location information control station transmits the location information request that has been generated to the base control station,

the base control station receives the location information request transmitted from the location information control station, and

the base control station transmits the location information request including the regional information in the location information request that has been received to the relay apparatus.

8. The radio communication method according to claim 7, wherein:

the relay apparatus receives the location information request transmitted from the base control station, and

the relay apparatus transmits the location information request to one or more base stations corresponding to the regional information in the location information request that has been received.
