Method and apparatus for updating a control file
First Claim
1. A method of transferring a control file from a source device to a remote device via a cellular communication network comprising the steps of:
- i. packing a control file into one or more Cell Broadcast message;
ii. transmitting the one or more Cell Broadcast message via one or more wireless transmitter;
iii. receiving the Cell Broadcast messages at a remote device; and
iv. extracting and reassembling the control file at the remote device.

Abstract
A method of simultaneously upgrading control files in mobile devices (5) and remote devices (45) utlising Cell Broadcast messages. A control file is divided into a number of packets which are sent in the user data sections (18, 20) of a sequence of Cell Broadcasts messages. The mobile data (5) or remote device (45) reassembles the packets (18, 20) and loads the control file if it passes error-checking tests. The control file may be operating software, operational parameters, control commands or SIM card files. The remote device may be a monitoring device, a consumer appliances, a vending machine etc. The method provides simultaneous “Flash upgrades” to multiple mobile devices in a transparent manner with minimal network overhead. A system for effecting the method and a remotely updatable device are also disclosed.
