Abstract

A reporting mobile station (800) operating in an ad-hoc wireless network (600) and method therein, receives, from the infrastructure (611), designation information (506) identifying a target mobile station, and stores (704) the designation information. The reporting mobile station then detects (706) a communication from the target mobile station, and stores (708) information (508) about the communication. The reporting mobile station then reports (710) the call information to a predetermined lawful intercept entity (612).

Claims

1. A method for providing information intercept in an ad-hoc wireless network, the method comprising:

receiving designation information at a reporter mobile station (MS) in the wireless network, said designation information identifying a target MS, wherein designation information includes specifying a surveillance type selected from (a) intercept-related information, (b) actual call content, and (c) both intercept-related information and actual call content;

storing said designation information in said reporter MS;

detecting a communication from said target MS by said reporter MS;

storing call information about said communication in said reporter MS; and

reporting said call information to a predetermined lawful intercept entity by said reporter MS.

2. A wireless communication device performing as a reporter mobile station (MS) for providing information intercept in an ad-hoc wireless network, the wireless communication device comprising:

a receiver for receiving designation information identifying a target MS said designation information specifying lawful intercept of signaling related call information for said target MS;

a processor coupled to said receiver for controlling the wireless communication device;

a first memory location coupled to said processor for storing said designation information;

a detector program coupled to said processor for programming said processor to detect a communication with said target MS;

a second memory location coupled to said processor for storing said signaling related call information about said communication; and

a reporter program coupled to said processor for programming said processor to report said signaling related call information to a lawful intercept entity.

3. The wireless communication device of claim 2, further comprising

a transmitter coupled to said processor for transmitting said signaling related call information to said lawful intercept entity.

4. The wireless communication device of claim 2,

wherein said target MS and the wireless communication device are the same MS, and

wherein said reporter program is arranged to program said processor to report the wireless communication device'"'"'s own communications in response to said designation information.

5. The wireless communication device of claim 2, wherein said first and second memory locations are accessible to said lawful intercept entity and not modifiable by a user of the wireless communication device.

6. The wireless communication device of claim 2, wherein said reporter program is arranged to program said processor to relay said signaling related call information through another MS operating in the ad-hoc wireless network.

7. The wireless communication device of claim 2, wherein said receiver and said processor are arranged and programmed to receive and respond to designation information comprising a surveillance type selected from (a) intercept-related information, (b) actual call content, and (c) both intercept-related information and actual call content.

8. The wireless communication device of claim 2, wherein said reporter program is arranged to program said processor to report billing information that is maintained by an operator of the ad-hoc wireless network.

9. The wireless communication device of claim 2,

further comprising a location-determining element for determining a position of said target MS during said communication, and

wherein said second memory location and said processor are arranged and programmed to store said position, and

wherein said reporter program is arranged to program said processor to report said signaling related call information in accordance with said position as compared with location parameters provided in said designation information.
