<p>A mobile communications system in which mobile radio transmitters (10, 11) communicate with each other via an infrastructure. The infrastructure (12) includes base stations (14, 16) and switching networks (15). The transmission is in the form of encrypted digitally encoded signals. The infrastructure is arranged to assemble a message for transmission to a transmitting or receiving radio, in response to recognition of a signal delay condition, this message containing information relating to the delay. This arrangement enables the system to minimise synchronisation errors. <IMAGE></p> |
