Abstract

Many mobile dispatch communication switch- ing controllers allow service to all subscribers at any time of day. This is accomplished by provisioning the subscribers into a Home Location Register (HLR), where they permanently remain. The sub- scriber's provisioning information is subsequently loaded into a Visitor Location Register (VLR) upon a request for service, where they reside until a life- time period time-out or in some cases, a successful de-registration is performed. Usually, this lifetime period is large in order to reduce the communica- tions necessary between the HLR and VLR.
