Mobile communications network, communications device, infrastructure equipment and methods

A communications device for use in a mobile communications network, the mobile communications network comprising a plurality of infrastructure equipment each providing wireless connectivity within at least one cell, wherein the communications device comprises

• transmitter circuitry configured to transmit signals to the infrastructure equipment,
• receiver circuitry configured to receive signals from the infrastructure equipment, and
• controller circuitry configured to control the transmitter circuitry and the receiver circuitry
• to communicate wirelessly with at least a first of the infrastructure equipment in control of a first cell,
• to determine whether a second cell under control of a second of the infrastructure equipment is connected to a first core network operating in accordance with a first communications protocol or both of the first core network and a second core network operating in accordance with a second communications protocol, the second cell being a neighbour of the first cell, and
• to transmit an automatic neighbour relation report to the first infrastructure equipment, the automatic neighbour relation report comprising an indication of whether the second cell is connected to the first core network or both of the first core network and the second core network.

An infrastructure equipment for use in a mobile communications network, the mobile communications network comprising one or more other infrastructure equipment, the infrastructure equipment and one or more other infrastructure equipment each providing wireless connectivity within at least one cell, and a communications device configured to communicate wirelessly with at least the infrastructure equipment, wherein the infrastructure equipment is in control of a first cell and comprises

• transmitter circuitry configured to transmit signals to the communications device and the other infrastructure equipment,
• receiver circuitry configured to receive signals from the communications device and the other infrastructure equipment, and
• controller circuitry configured to control the transmitter circuitry and the receiver circuitry
• to receive an automatic neighbour relation report from the communications device, the automatic neighbour relation report comprising an indication of whether a second cell under control of one of the other infrastructure equipment is connected to a first core network operating in accordance with a first communications protocol or both of the first core network and a second core network operating in accordance with a second communications protocol, the second cell being a neighbour of the first cell.

An infrastructure equipment for use in a mobile communications network, the mobile communications network comprising one or more other infrastructure equipment, the infrastructure equipment and other infrastructure equipment each providing wireless connectivity within at least one cell, wherein the infrastructure equipment is in control of a first cell and comprises

• transmitter circuitry configured to transmit signals to the other infrastructure equipment,
• receiver circuitry configured to receive signals from the other infrastructure equipment, and
• controller circuitry configured to control the transmitter circuitry and the receiver circuitry
• to transmit a connection setup request message to one of the other infrastructure equipment in control of a second cell, the connection setup request message comprising an indication of whether the first cell is connected to a first core network operating in accordance with a first communications protocol or both of the first core network and a second core network operating in accordance with a second communications protocol, the second cell being a neighbour of the first cell.
