ABSTRACT:
A command, such as an application specific command, is communicated from a central host to a remote station via a cellular mobile radio network. The station may be a fixed or roaming device. The central host sends the command a network switch, such as an SS7 SSP, wherein the command comprises a mobile identification number (MIN) and an electronic serial number (ESN). The network switch queries an associated HLR database to locate the remote station, the query specifying the MIN and the ESN. If the HLR does not recognize the MIN/ESN combination, it so informs the network switch, as well as the VLR associated with the MSC serving a remote station identified by the ESN. In response to the notification from the HLR, the VLR removes any entry in its database relating to the ESN and updates its database with the new MIN/ESN combination transmitted by the HLR to the VLR. The VLR confirms with the HLR that it has taken these steps and then sends the command to the remote station by calling the station using the new MIN/ESN.
