Abstract

A server may detect a threshold number of mobile stations (e.g., total mobile stations or mobile stations belonging to a predefined group) currently located at an area, such as by determining that a number of mobile stations currently located at an area is greater than a desired maximum number of mobile stations or less than a desired minimum number of mobile stations. The threshold number may be determined based on a typical number of mobile stations located at the area. In response to detecting the threshold number of mobile stations, the server may obtain data recorded by surveillance equipment located at the area (including data recorded by mobile stations temporarily acting as surveillance equipment,) which data represents activity at the area. To obtain the data, the server may instruct the surveillance equipment to begin recording data. The server may then output the received data for receipt by a user.

Claims

1. A method of monitoring activity at a given area, the method comprising:

maintaining, at one or more servers, historical data indicating a number of mobile stations previously located at the given area;

defining a threshold number of mobile stations located at the given area based on the historical data;

detecting the threshold number of mobile stations located at the given area;

in response to detecting the threshold number of mobile stations located at the given area, sending a request for data recorded by surveillance equipment located at the given area, wherein the data represents activity at the given area; and

as a result of sending the request, receiving data recorded by the surveillance equipment.

2. The method of claim 1, wherein the surveillance equipment comprises a digital video camera and the data comprises digital video.

3. The method of claim 1, wherein the surveillance equipment comprises a microphone and the data comprises audio.

4. The method of claim 1, wherein the data recorded by the surveillance equipment comprises data that was previously recorded by the surveillance equipment.

5. The method of claim 1, wherein the data recorded by the surveillance equipment comprises real-time data.

6. The method of claim 1, wherein the threshold number represents a desired maximum number of mobile stations located at the given area, and wherein detecting the threshold number of mobile stations located at the given area comprises:

determining a number of mobile stations currently located at the given area; and

determining that the number of mobile stations currently located at the given area is greater than the threshold number.

7. The method of claim 1, wherein the threshold number represents a desired minimum number of mobile stations located at the given area, and wherein detecting the threshold number of mobile stations located at the given area comprises:

determining a number of mobile stations currently located at the given area; and

determining that the number of mobile stations currently located at the given area is less than the threshold number.

8. The method of claim 1, wherein the historical data indicating a number of mobile stations previously located at the given area comprises historical data indicating a number of mobile stations previously located at the given area during a particular time period.

9. The method of claim 1, wherein the mobile stations consist of mobile stations belonging to a predefined group.

10. The method of claim 9, wherein the mobile stations in the predefined group comprise mobile stations associated with criminals.

11. The method of claim 1, wherein the request for data recorded by surveillance equipment located at the given area comprises an instruction for the surveillance equipment to begin recording data.

12. The method of claim 1, further comprising:

outputting the obtained data for receipt by a user.

13. The method of claim 1, further comprising:

in response to detecting the threshold number of mobile stations located at the given area, alerting a law enforcement agency.

14. A method of monitoring activity at a given area, the method comprising:

maintaining, at one or more servers, historical data indicating a number of mobile stations previously located at the given area;

defining a threshold number of mobile stations located at the given area based on the historical data;

detecting the threshold number of mobile stations located at the given area;

in response to detecting the threshold number of mobile stations located at the given area, sending a request for data recorded by one or more mobile stations located at the given area, wherein the data represents activity at the given area; and

as a result of sending the request, receiving data recorded by the one or more mobile stations.

15. The method of claim 14, wherein the request for data recorded by one or more mobile stations located at the given area comprises an instruction for the one or more mobile stations to begin recording data.

16. A server comprising:

a communication interface for communicating with an access network and surveillance equipment located at a given area;

a processor;

data storage; and

program instructions stored in the data storage and executable by the processor for;

maintaining historical data indicating a number of mobile stations previously located at the given area;

defining a threshold number of mobile stations located at the given area based on the historical data;

detecting the threshold number of mobile stations located at the given area; and

in response to detecting the threshold number of mobile stations located at the given area, obtaining data recorded by surveillance equipment located at the given area, wherein the data represents activity at the given area.

17. The server of claim 16, further comprising a user interface for outputting the obtained data.

18. The server of claim 16, wherein the data storage contains:

data defining the given area;

data indicating entities in the access network that serve the given area;

data indicating surveillance equipment located at the given area; and

data indicating a number of mobile stations located at the given area.
