Abstract
A mobile communication network 12 provides communication between devices 10 and is controlled at 14. When a user wishes to gain access to the network 12, a device 10 is required to send a request signal to the control 14. This request signal identifies the user device, not the user. The control makes security checks to ensure that the device is authorised, before returning an authorising signal 20. The user device is configured to prevent communication by the user until an authorising signal has been received. Security is improved by requiring the user device to be identified. Details of devices 10 which have been stolen can be recorded by the control 14 so that those devices will not, in future, be authorised for use of the network 12. The value of a stolen device 10 to a thief is therefore reduced or removed.
