Abstract:
1. A method of communications between a gateway transceiver in a fixed network and a plurality of site transceivers associated with respective meter reading devices, the method comprising: receiving an incoming message from one of the site transceivers at a gateway fixed transceiver, including meter reading data from a meter reading device associated with the site transceiver, and then first, checking the message for a first gateway address of a mobile gateway; and upon not detecting the first gateway address, then checking the message for a second gateway address of a gateway to which the site transceiver associated with the meter reading device is assigned; and upon not detecting the second gateway address, then, checking the message for a global gateway address; and upon detecting the first gateway address for a mobile gateway, the gateway fixed transceiver skips further processing of the incoming message; upon detecting the second gateway address from a site transceiver associated with the meter reading device indicating that the meter reading device is assigned to this gateway, the meter reading data in the message is stored in memory and a reply message is transmitted if necessary to the site transceiver associated with the meter reading device; and upon detecting a global gateway address, a further check is made to determine if the site transceiver associated with the meter reading device is assigned to this gateway, and if so assigned, the meter reading data in the message is stored in memory and a reply message is transmitted, if necessary, to the site transceiver associated with the meter reading device, and if not so assigned, then data in the message is stored in memory to record that the message was received, but a reply message is not transmitted.
