A communications system comprises a mobile radio network which includes a plurality of base stations which are arranged to communicate data to and from mobile communications devices via a wireless access interface. The system also includes a plurality of associated communications devices each of the associated communications devices being capable of transmitting and receiving data from one or more of the base stations. Each of the associated communications devices of the group includes the same common identifier with respect to which communication sessions can be established to communicate data via the mobile radio network from any of the associated communications devices. The group of communications devices may be for communicating machine type communications (MTC) for a particular application such as for example, being disposed in a vehicle such as a car in order to report certain parameters. Each of these parameters may be served by a separate communications device which reports periodically on the parameters which are detected by an associated sensor. As such because of the spatial proximity of each of the communications devices, each is able to receive control plane signalling data and accordingly the communication of the signalling data is as if broadcast to a local environment in which the group of communications devices are disposed. Accordingly, there is a saving in communications bandwidth which is proportional to the number of the devices in the group. |
