System and method for reporting change of area event
First Claim
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 that specifies 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, the predetermined location being covered by a plurality of cells and each cell being represented by a corresponding cell id;
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;
triggering an armed event, inside the MSC, in response to the UE entering a selected cell of the plurality cells, wherein the armed event corresponds to sending a Subscriber Location Report (SLR);
receiving, by the MSC, one or more location updates transmitted by the UE, each location update indicating a current location of the UE;
determining, by the MSC, whether the change of area event that is specified in the LCS request has occurred,the determination by the MSC being based on the one or more location updates indicating the UE entering the selected and the triggering of the armed event, and wherein the MSC considers the selected cell for determining whether the change of area event has occurred based on the selected cell being the first of the plurality of cells that the UE entered;
sending the SLR to the VGMLC reporting a failure of the change of area event when the UE does not enter the selected cell within a predetermined time limit; and
sending, by the MSC, the SLR to the VGMLC based on a determination by the MSC that a change of area event for the UE has occurred.

Abstract
The instant amendment is provided as a complete replacement to the amendment filed on Jul. 10, 2012. The instant amendment is submitted to correct a typographical error found in the previously-filed amendment. Claims 1 and 13 in the previously-filed amendment incorrectly recite “when it is determined by the MSC that a change of area event for the UE has occurred, forwarding a Subscriber Location Report (SLR) from the MSC to the VGMLC when it is determined by the MSC that a change of area event for the UE has occurred,” whereas they should have recited “forwarding a Subscriber Location Report (SLR) from the MSC to the VGMLC when it is determined by the MSC that a change of area event for the UE has occurred,” instead.

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 that specifies a 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; trigger an armed event for a selected cell of the plurality of cells, the armed event corresponding to the sending a Subscriber Location Report (SLR) when the UE enters the selected cell; receive one or more location updates from the UE, each location update identifying a current location of the UE; determine whether the change of area event that is specified in the LCS request has occurred, the determination by the MSC being based on a selected location update of the one or more location updates indicating entrance of the UE in the selected cell and the triggering of the armed event, wherein the MSC considers the selected cell for determining whether the change of area event specified in the LCS request has occurred based on the selected cell being the first of the plurality of cells that the UE entered; send the Subscriber Location Report (SLR) to the VGMLC when it is determined by the MSC that a change of area event for the UE has occurred; and send the SLR to the VGMLC reporting a failure of the change of area event when the UE does not enter the selected cell within a predetermined time limit; and a VGMLC associated with the MSC configured to; send the location update report to the HGMLC based on the SLR. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)

21. A method for reporting change of area event in a communications network, the method comprising:
-
receiving, at a Mobile Switching Center (MSC) that is part of the communications network, a Location Service (LCS) request, the request specifying a change of area event for a User Equipment (UE) for the predetermined location, the predetermined location being covered by a plurality of cells and each cell being represented by a corresponding cell id; receiving, by the MSC, one or more location updates transmitted by the UE, each update indicating a current location of the UE; triggering an armed event, inside the MSC, for a selected cell of the plurality of cells, the armed event corresponding to sending a Subscriber Location Report (SLR) when the UE enters the selected cell; determining, by the MSC, whether the change of area event that is specified in the LCS request has occurred, the determination by the MSC being based on an entrance of the UE in the selected cell and the triggering of the armed event; sending, by the MSC, the SLR to another device, when it is determined that a change of area event for the UE has occurred; and sending the SLR to the another device reporting a failure of the change of area event when the UE does not enter the selected cell within a predetermined time limit.
