Communication device and method for communicating data using a common identifier

摘要

A communications device, communicating data via a mobile radio network, includes a transmitter/receiver communicating data to/from a mobile radio network via a wireless access interface, and a module storing information identifying the communications device to the mobile radio network, the stored information including a same common identifier in each of an associated group of communications devices, the common identifier to establish communications sessions to communicate data to/from any of the associated communications devices. The group of communications devices may communicate machine type communications for a particular application, for example disposed in a vehicle, to report certain parameters. With spatial proximity of the communications devices, each can receive control plane signalling data and accordingly communication of signalling data is as if broadcast to a local environment in which the group of communications devices are disposed, to save communications bandwidth proportional to the number of devices in the group.

主权项

1. A communications device for communicating data via a mobile radio network, the communications device comprising:
processing circuitry configured to store information that identifies the communications device to the mobile radio network; and a transmitter and receiver configured to
communicate data to or from the mobile radio network via a wireless access interface of the mobile radio network, the wireless access interface including a random access communications channel for uplink transmission of a burst of signals;transmit a random access burst in the random access communications channel in accordance with a predetermined arrangement; andreceive a signalling message in response to the random access burst, the signalling message using a unique predefined sequence, wherein the communications device is provided with the unique predefined sequence, which is a set of predefined sequences of data unique to the communications device for forming the random access burst that is transmitted in the random access channel of the wireless access interface, the information includes a same common identifier as that provided to each of an associated group of communications devices, the common identifier used to establish a communication session to communicate data to or from any communications device of the associated group of communications devices, and each communications device of the group of communications devices receives signalling information from the mobile radio network, the signalling information including information required for mobility management and connection.
