Abstract
A base station, communication control method used in a base station, and mobile communication system including a base station transmit a handover request message for handing over a wireless communication apparatus having a RRC connection with the base station to another base station. The handover message includes an Integrated Access and Backhaul (IAB) indication indicating that the wireless communication apparatus is an IAB node having a user equipment function and a base station function.
Claims4
A base station comprising:
- a network communicator configured to transmit a handover request message for handing over a wireless communication apparatus having a RRC connection with the base station to another base station, wherein
- the handover request message includes an Integrated Access and Backhaul (IAB) indication indicating that the wireless communication apparatus is an IAB node having a user equipment function and a base station function,
- the IAB node has a UE function configured to perform radio communication with an upper node and a gNB function configured to perform radio communications with a lower node,
- the base station comprises a transmitter configured to broadcast a System Information Block (SIB) including information indicating that the base station supports the IAB node, and
- the network communicator is configured to transmit the IAB indication to an Access and Mobility Management Function (AMF) included in a core network.
A communication control method used in a base station, the method comprising:
- transmitting a handover request message for handing over a wireless communication apparatus having a RRC connection with the base station to another base station, wherein
- the handover request message includes an Integrated Access and Backhaul (IAB) indication indicating that the wireless communication apparatus is an IAB node having a user equipment function and a base station function,
- the IAB node has a UE function configured to perform radio communication with an upper node and a gNB function configured to perform radio communications with a lower node, and
- the method further comprises
- broadcasting a System Information Block (SIB) including information indicating that the base station supports the IAB node, and
- transmitting the IAB indication to an Access and Mobility Management Function (AMF) included in a core network.
