Abstract:
A backward location update method for location management in wireless PCNs is provided. The VLR employs an intelligent micro procedure to determine different types of location update requests and performs a backward location update in the HLR only when required by call or short message delivery. Accordingly, the VLR avoids unnecessary location updates in the HLR.
