Abstract
A method of operating a source central unit (CU) of a wireless communications network is provided. The method includes communicating signals with a communications device operating in a connected state with the source CU, determining that the device is to hand over to a target CU, and performing a handover procedure with the device and the target CU. The handover procedure uses signalling only at a physical layer and/or a data link layer at the source CU, the target CU, and the device. The method further includes controlling, for a specified time period following the handover procedure, a target distributed unit (DU) associated with the target CU.
Claims20
A method of operating a source central unit, CU, of a wireless communications network, the method comprising
- transmitting signals to and/or receiving signals from a communications device which is operating in a connected state with the source CU,
- determining that the communications device is to hand over from the source CU to a target CU of the wireless communications network,
- performing, with the communications device and the target CU, a handover procedure to hand the communications device over from the source CU to the target CU, wherein the handover procedure consists of signalling only at a physical layer at each of the source CU, the target CU, and the communications device and/or a data link layer at each of the source CU, the target CU, and the communications device, and
- controlling, for a specified time period following the handover procedure, a target distributed unit, DU, associated with the target CU.
A source central unit, CU, of a wireless communications network, the source CU comprising
- transceiver circuitry configured to transmit signals to and/or to receive signals, and
- controller circuitry configured in combination with the transceiver circuitry
- to transmit signals to and/or receiving signals from a communications device which is operating in a connected state with the source CU,
- to determine that the communications device is to hand over from the source CU to a target CU of the wireless communications network,
- to perform, with the communications device and the target CU, a handover procedure to hand the communications device over from the source CU to the target CU, wherein the handover procedure consists of signalling only at a physical layer at each of the source CU, the target CU, and the communications device and/or a data link layer at each of the source CU, the target CU, and the communications device, and
- to control, for a specified time period following the handover procedure, a target distributed unit, DU, associated with the target CU.

A target central unit, CU, of a wireless communications network, the target CU comprising
- transceiver circuitry configured to transmit signals to and/or to receive signals, and
- controller circuitry configured in combination with the transceiver circuitry
- to determine that a communications device is to hand over from a source CU of the wireless communications network to the target CU,
- to perform, with the communications device and the source CU, a handover procedure to hand the communications device over from the source CU to the target CU, wherein the handover procedure consists of signalling only at a physical layer at each of the source CU, the target CU, and the communications device and/or a data link layer at each of the source CU, the target CU, and the communications device, and
- to determine that, for a specified time period following the handover procedure, a target distributed unit, DU, associated with the target CU will be controlled by the source CU.
