Abstract

A system and method of controlling the operation of the wireless communications between a mobile device and access point by monitoring and modifying the communications.

Claims

1. In a wireless communication network having a mobile device which communicates with an access point and having a repeater system comprised of at least one distributed antennas to extend the coverage of the wireless signals transmitted between the mobile device and the access point, a method comprising:

(a) at, through or in association with a distributed antenna, receiving a first RF communication signal;

(b) converting the first RF communication signal to a digital signal;

(c) monitoring the converted digital signal to retrieve communication information;

(d) controlling the operation of the mobile device as a function of the retrieved communication information.

2. The method of claim 1 wherein the first communication signal is a control message from a base station to a mobile telephone.

3. The method of claim 1 wherein the first communication signal is a control message from a mobile telephone to a base station.

4. The method of claim 1 wherein the first communication signal is a user message from a mobile device to an access point

5. The method of claim 1 wherein the first communication signal is a user message from an access point to a mobile device.

6. The method of claim 2 wherein the retrieved communication information is one of identity of the mobile device, location of the mobile device, identity of the mobile device user, configuration or status of the mobile device, configuration or status of the base station, configuration or status of the wireless network, measurements on the wireless network signals made at the mobile devices, measurements on the wireless network signals made at the base stations, and content of the message transmitted

7. The method of claim 6 wherein the step of controlling includes denying service to the mobile device.

8. The method of claim 6 wherein the step of controlling includes permitting or inducing a specific type of communication.

9. The method of claim 8 wherein the specific type of communication includes one of control message, user message, short message service (SMS), control, and a multimedia message service (MMS).

10. The method of claim 1 wherein the step of monitoring includes

(i) creating connections to or around the distributed antenna system to access a forward link wireless signal from the access point to the mobile device or a reverse link wireless signal from a mobile device to the access point,

(ii) synchronizing with the forward link or reverse link signals, and

(iii) determining the content in the synchronized signals

11. The method of claim 2 wherein the step of controlling further comprises the steps of:

(i) creating a second RF signal based on the received first RF signal; and

(ii) transmitting the second RF signal to the mobile device.

12. The method of claim 11 wherein the step of creating includes inserting a message into the second RF signal

13. The method of claim 12 wherein the second RF message is one of a control message, a user message, an SMS, or a multimedia message service (MMS).

14. The method of claim 12 wherein the second RF message instructs the mobile device to shutdown.

15. The method of claim 12 wherein the second RF message instructs the mobile device to transmit an identification signal.

16. The method of claim 11 wherein the step of creating includes blanking a portion of the first digital signal.

17. The method of claim 4 wherein the step of controlling further comprises the steps of:

(i) creating a second RF signal based on the received first RF signal; and

(ii) transmitting the second RF signal to the access point.

18. The method of claim 17 wherein the step of creating includes inserting a message into the second RF signal

19. The method of claim 18 wherein the second RF message is one of a control message, a user message, an SMS, or a multimedia message service (MMS).

20. The method of claim 1 further comprising the step of measuring a characteristic of the first received signal.

21. The method of claim 20 further comprising the step of determining the location of the mobile device at least partially based on the measured characteristic.
