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, at a location based proximity alert physical server, a current location of a wireless client device associated with a given restraining order target identifier;

accessing a law enforcement database comprising a 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 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 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 associated with said restraining order requester identifier, and a wireless client 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 restraining order limit identifier;

a location access module to retrieve, from said location based proximity alert physical server, a current location of said restraining order target; and

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

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

said 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 if a distance between said wireless client associated with said restraining order requester identifier is less than a preconfigured minimum distance to a wireless client 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.
