Abstract

A mobile communications network includes a core network including infrastructure equipment, and a radio network including plural base stations configured to provide a wireless access interface for communicating data to/from communications terminals. One base station can operate as a serving base station to one of the communications terminals, to establish one or more communications bearers for communicating user data to/from the communications terminal via the core network and the radio network, and co-operate with at least another of the base stations to communicate the user data to/from the communications terminal. The mobile communications network can monitor a state of a radio communications channel between the co-operating base station and the communications terminal, and upon predetermined conditions, establish a communications bearer from the core network to the co-operating base station for communicating the user data to the co-operating base station for transmitting the user data to the communications terminal.

Claims12

Dependent claims

A communications terminal for communicating data to or receiving data from a mobile communications network, the mobile communications terminal being configured

to establish in co-operation with the mobile communications network a communications bearer for communicating data for a communications session from or to the mobile communications device via the communications bearer, the communications bearer including a radio communications channel between the communications terminal and a serving base station of the mobile communications network, and
to receive the data from a serving base station of the mobile communications network via a radio communications channel between the serving base station and the communications terminal, wherein the serving base station forms with at least one other co-operating base station a co-operating set, and the communications terminal is configured
to determine a state of the radio communications channel between the serving base station and the communications terminal and between the co-operating base station and the communications terminal,
to communicate the determined state of the radio communications channel between the serving base station and the co-operating base station and the communications terminal to the serving base station,
to receive the user data selectively from one or both of the serving base station or the co-operating base station consequent upon the communicated state of a radio communications channel established via the wireless access interface under the control of the serving base station, and
consequent upon predetermined conditions, to receive the user data from the co-operating base station, which has been communicated to the co-operating base station using a communications bearer established from the core network to the co-operating base station for communicating the user data to the co-operating base station for transmitting the user data to the communications terminal.

3 more elements

A method of communicating data from a communications terminal via a mobile communications network, the mobile communications network comprising a core network part including infrastructure equipment, and a radio network part including a plurality of base stations which are configured to provide a wireless access interface for communicating the data to the communications terminals, the method comprising

establishing in co-operation with the mobile communications network a communications bearer for communicating data for a communications session from or to the mobile communications device via the communications bearer, the communications bearer including a radio communications channel between the communications terminal and a serving base station of the mobile communications network, and
receiving the data from a serving base station of the mobile communications network via a radio communications channel between the serving base station and the communications terminal, wherein the serving base station forms with at least one other co-operating base station a co-operating set, and the communications terminal is configured
determining a state of the radio communications channel between the serving base station and the communications terminal and between the co-operating base station and the communications terminal,
communicating the determined state of the radio communications channel between the serving base station and the co-operating base station and the communications terminal to the serving base station,
receiving the user data selectively from one or both of the serving base station or the co-operating base station consequent upon the communicated state of a radio communications channel established via the wireless access interface under the control of the serving base station, and
consequent upon predetermined conditions, receiving the user data from the co-operating base station, which has been communicated to the co-operating base station using a communications bearer established from the core network to the co-operating base station for communicating the user data to the co-operating base station for transmitting the user data to the communications terminal.
