Abstract

A system and method for reporting change of area event is provided. The method comprises the steps of receiving a Location Service (LCS) request from an LCS Client to report a change of area event for a User Equipment (UE) for a predetermined location; obtaining an address of a Mobile Switching Center (MSC) associated with the predetermined location; establishing a connection with the MSC associated with the predetermined location; forwarding the LCS request to a Visited Gateway Mobile Location Center (VGMLC) associated with the MSC when the connection is established; checking whether a change of area event has occurred for the UE by monitoring location update of the UE at the MSC; forwarding a Subscriber Location Report (SLR) from the MSC to the VGMLC when the change of area event occurs for the UE; and sending a location update report from the Home Gateway Mobile Location Center (HGMLC) to the LCS Client.

Claims

1. A method for reporting change of area event, the method comprising the steps of:

receiving a Location Service (LCS) request from an LCS Client to report a change of area event for a User Equipment (UE) for a predetermined location;

obtaining an address of a Mobile Switching Center (MSC) associated with the predetermined location;

establishing a connection with the MSC associated with the predetermined location;

forwarding the LCS request to a Visited Gateway Mobile Location Center (VGMLC) associated with the MSC when the connection is established;

checking whether a change of area event has occurred for the UE by monitoring location update of the UE at the MSC;

forwarding a Subscriber Location Report (SLR) from the MSC to the VGMLC when the change of area event occurs for the UE; and

sending a location update report from the Home Gateway Mobile Location Center (HGMLC) to the LCS Client.

2. The method of claim 1, wherein the change of area event occurs when the UE moves into the predetermined location.

3. The method of claim 1, wherein the change of area event occurs when the UE leaves the predetermined location.

4. The method of claim 1, wherein the change of area event occurs when the UE stays in the predetermined location.

5. The method of claim 1 further comprising the steps of:

decoding the predetermined location into one or more cell identities (ids); and

obtaining the address of the MSC serving one or more cell ids.

6. The method of claim 1 further comprising the step of checking whether the connection with the MSC is established.

7. The method of claim 1 further comprising the step of sending a Provide Subscriber Location (PSL) request from the VGMLC to the MSC of the predetermined location.

8. The method of claim 7 further comprising the step of transmitting a PSL acknowledgement from the MSC of the predetermined location to the VGMLC.

9. The method of claim 1 further comprising the step of checking whether a timer has timed out when the change of area event does not occur for the predetermined location.

10. The method of claim 9, wherein a value of the timer is set by a user managing the LCS Client.

11. The method of claim 9 further comprising the step of indicating a failure of invocation of change of area event when the timer has timed out.

12. The method of claim 1 further comprising the step of receiving a SLR acknowledgment at the MSC from the VGMLC of the predetermined location.

13. A communication network for reporting change of area event, the communication network comprising:

a User Equipment (UE);

a Location Services (LCS) client configured to

send an LCS request to report change of area event for the UE for a predetermined location;

a Home Gateway Mobile Location Center (HGMLC) configured to

receive the LCS request from the LCS Client;

secure an address of a Mobile Switching Center (MSC) associated with the predetermined location;

forward the LCS request to a Visited GMLC (VGMLC) associated with the MSC; and

send a location update report to the LCS Client;

an MSC associated with the predetermined location configured to

check whether a change of area event has occurred for the UE by monitoring location update of the UE; and

send a Subscriber Location Report (SLR) to the VGMLC when the change of area event occurs for the UE; and

a VGMLC associated with the MSC configured to

send the location update report to the HGMLC based on the SLR.

14. The communication network of claim 13 further comprising an application server configured to

decode geopolitical name of the predetermined location;

and

return an address of the MSC serving the predetermined location.

15. The communication network of claim 13, wherein the VGMLC is further configured to

send a Provide Subscriber Location (PSL) request to the MSC of the predetermined location;

and

send a SLR acknowledgement to the MSC.

16. The communication network of claim 15, wherein the MSC is further configured to transmit a PSL acknowledgement to the VGMLC.

17. The communication network of claim 13 further comprising a Requesting GMLC (RGMLC) configured to receive at least one or more LCS request generated by the LCS Client.

18. The communication network of claim 13, wherein the HGMLC is an LCS Server.

19. The communication network of claim 13, wherein the UE is an electronic communication device.

20. The communication network of claim 13, wherein the UE may be one of the following:

a mobile phone, a hand held device, a personal digital assistant, or a blackberry.
