Infrastructure equipment and method

摘要

An infrastructure equipment for forming part of a mobile radio network includes a transmit and receive unit, to transmit and receive data to and from mobile communications devices via a wireless access interface, and a controller processing requests for communications resources from the mobile communications devices. Plural associated communications devices are arranged to form a group, and each of the associated communications devices of the group includes a same common identifier, with respect to which communications sessions can be established to communicate data via the mobile radio network, and the controller is arranged in combination with the transmit and receive unit to respond to a request from one of the communications devices of the group to establish a communications bearer using the common identifier.

1. An infrastructure equipment for forming part of a mobile radio network, the infrastructure equipment including
a transceiver configured to transmit and receive data to and from communications devices via a wireless access interface, and a controller configured to
process requests for communications resources from the communications devices, wherein a plurality of associated communications devices are arranged to form each of plural groups, and each of the associated communications devices of a respective group includes the same common identifier,respond to a request from one of the communications devices of the respective group to establish a communications session using the common identifier, the communications session being used to communicate data to and from any of the communications devices of the respective group,provide each of the communications devices within each of the plural groups of associated communications devices with a unique one of a set of predefined sequences of data for use in forming a random access burst for transmission in a random access channel of the wireless access interface, a different set of predefined sequences being uniquely associated with each respective group, andtransmit a message in response to a random access burst, using the predefined sequence which was used to form the random access burst received from a communications device.
