Abstract

A method of location based proximity alert retrieves, from a location based proximity alert physical server, a current location of wireless client devices and determines if it is within a given area. The method accesses, from the location based proximity alert physical server, a physical law enforcement database comprising a restraining order target identifier and a restraining order limit identifier. A geo-proximity alert message is transmitted if the current location of the restraining order target identifier matches the restraining order limit identifier.

Claims

1. A method of providing location-based proximity alert services, comprising:

retrieving, by a location-based proximity alert physical server, a current location of a wireless client device, said current location being based on call-routing information associated with said wireless client device, said call-routing information being registered in a location device servicing said wireless client device device, and said wireless client device associated with a given restraining order target identifier from a plurality of restraining order target identifiers;

accessing a law enforcement database comprising said plurality of restraining order target identifiers, each associated with a corresponding restraining order limit identifier, to obtain a relevant restraining order limit identifier associated with said given restraining order target identifier; and

generating a geo-proximity alert message when said current location is within a prohibited geographic area associated with said given restraining order target identifier.

2. The method of providing location-based proximity alert services according to claim 1, wherein:

said given restraining order target identifier is a mobile identification number (MIN).

3. The method of providing location-based proximity alert services according to claim 1, wherein:

said given restraining order target identifier is a mobile telephone number.

4. The method of providing location-based proximity alert services according to claim 1, further comprising:

determining a distance between said wireless client device associated with said given restraining order target identifier, and a wireless client device requesting said geo-proximity alert message.

5. The method of providing location-based proximity alert services according to claim 1, wherein:

said prohibited geographic area associated with said given restraining order target identifier is a prohibited perimeter around a given school.

6. The method of providing location-based proximity alert services according to claim 1, wherein:

said prohibited geographic area associated with said given restraining order target identifier is a prohibited perimeter around a given park.

7. The method of providing location-based proximity alert services according to claim 1, wherein:

said geo-proximity alert message is an email message.

8. A location-based proximity alert physical server, comprising:

a law enforcement database access module to access a physical law enforcement database comprising a plurality of restraining order target identifiers each associated with a given restraining order limit identifier;

a location access module, at said location-based proximity alert physical server, to retrieve a current location of a wireless client device, said current location being based on call-routing information associated with said wireless client device, said call-routing information being registered in a location device servicing said wireless client device, and said wireless client device associated with a given restraining order target identifier from said plurality of restraining order target identifiers; and

a restraining order violation module to generate a geo-proximity alert message when said current location for a restraining order target enters a prohibited geographic area associated with said given restraining order limit identifier.

9. The location-based proximity alert physical server according to claim 8, wherein:

said given restraining order target identifier is a mobile identification number (MIN).

10. The location-based proximity alert physical server according to claim 8, wherein:

said restraining order violation module generates said geo-proximity alert message when said wireless client device associated with said restraining order target is less than a preconfigured minimum distance from another wireless client device requesting said geo-proximity alert message.

11. The location-based proximity alert physical server according to claim 8, wherein:

said prohibited geographic area associated with said given restraining order target identifier is a prohibited perimeter around a given school.

12. The location-based proximity alert physical server according to claim 8, wherein:

said prohibited geographic area associated with said given restraining order target identifier is a prohibited perimeter around a given park.

13. The location-based proximity alert physical server according to claim 8, wherein:

said geo-proximity alert message is an email message.
