Patent ID: 8504060

Claim:
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.
