Cellular network communication between assets and a central server

摘要

In a method of communicating between a central server and a plurality of assets over a cellular network in communication with the central server, each asset has a transceiver arranged to communicate with the cellular network which includes an integrated circuit card identifier (ICCID) and an international mobile subscriber identity (IMSI). The ICCID of each transceiver is unique, but the IMSI of multiple transceivers are identical to one another. Communication between the assets and the central server is initiated by the asset transceivers and is rescheduled automatically in the event that another transceiver with the same IMSI is already communicating with the central server. Communication from the server to the asset transceivers involves queuing data until the transceiver of the intended recipient transceiver contacts the central server.

1. A method of communicating between a central server and a plurality of assets over a cellular network in communication with the central server, the method comprising:
i) providing each asset with a transceiver arranged to communicate with the cellular network in which each transceiver includes an integrated circuit card identifier and an international mobile subscriber identity such that:
a) the integrated circuit card identifier of each transceiver is unique; andb) the international mobile subscriber identity of at least two transceivers are in common with one another; and ii) for each asset, using the transceiver of the asset, periodically initiating communication between the asset and the central server over the cellular network, and transmitting the integrated circuit card identifier of the asset to the central server upon successful connection between the asset and the central server over the cellular network; iii) upon successful connection between one of said at least two transceivers having the same international mobile subscriber identity and the central server over the cellular network, distinguishing which one of said at least two transceivers is connected to the central server using the integrated circuit card identifier that was transmitted to the central server from the transceiver.
