Abstract
In a first aspect, a communication control method is used in a cellular communication system. The communication control method includes: detecting, by a relay node, an occurrence of a failure in a backhaul link between the relay node and one of parent nodes of a first parent node and a second parent node, the relay node being configured with dual connectivity for the first parent node and the second parent node; and transmitting, by the relay node, a notification relating to detection of the failure to a child node of the relay node, when the relay node is not capable of uplink rerouting.

A communication control method used in a cellular communication system, the communication control method comprising steps of:
- detecting, by a relay node, an occurrence of a failure in a backhaul link between the relay node and one of parent nodes of a first parent node and a second parent node, the relay node being configured with dual connectivity for the first parent node and the second parent node;
- and
- transmitting, by the relay node, a notification relating to detection of the failure to a child node of the relay node, when the relay node is not capable of uplink rerouting;
- wherein
- the transmitting the notification relating to detection of the failure is conducted when the relay node operates in EN-DC and the failure in the backhaul link is occurred between the second parent node and the relay node forming the backhaul link with the second parent node.
A relay node comprising transceiver circuitry and processing circuitry operatively associated with the transceiver circuitry and configured to execute processes of:
- detecting, by a relay node, an occurrence of a failure in a backhaul link between the relay node and one of parent nodes of a first parent node and a second parent node, the relay node being configured with dual connectivity for the first parent node and the second parent node;
- and
- transmitting, by the relay node, a notification relating to detection of the failure to a child node of the relay node, when the relay node is not capable of uplink rerouting;
- wherein
- the transmitting the notification relating to detection of the failure is conducted when the relay node operates in EN-DC and the failure in the backhaul link is occurred between the second parent node and the relay node forming the backhaul link with the second parent node.
A cellular communication system comprising a relay node, wherein the relay node includes transceiver circuitry and processing circuitry operatively associated with the transceiver circuitry and configured to execute processes of:
- detecting, by a relay node, an occurrence of a failure in a backhaul link between the relay node and one of parent nodes of a first parent node and a second parent node, the relay node being configured with dual connectivity for the first parent node and the second parent node;
- and
- transmitting, by the relay node, a notification relating to detection of the failure to a child node of the relay node, when the relay node is not capable of uplink rerouting;
- wherein
- the transmitting the notification relating to detection of the failure is conducted when the relay node operates in EN-DC and the failure in the backhaul link is occurred between the second parent node and the relay node forming the backhaul link with the second parent node.
A non-transitory computer readable storage medium storing a program including processes of:
- detecting, by a relay node, an occurrence of a failure in a backhaul link between the relay node and one of parent nodes of a first parent node and a second parent node, the relay node being configured with dual connectivity for the first parent node and the second parent node;
- and
- transmitting, by the relay node, a notification relating to detection of the failure to a child node of the relay node, when the relay node is not capable of uplink rerouting;
- wherein
- the transmitting the notification relating to detection of the failure is conducted when the relay node operates in EN-DC and the failure in the backhaul link is occurred between the second parent node and the relay node forming the backhaul link with the second parent node.
A chipset comprising circuitries configured to execute processes of:
- detecting, by a relay node, an occurrence of a failure in a backhaul link between the relay node and one of parent nodes of a first parent node and a second parent node, the relay node being configured with dual connectivity for the first parent node and the second parent node;
- and
- transmitting, by the relay node, a notification relating to detection of the failure to a child node of the relay node, when the relay node is not capable of uplink rerouting;
- wherein
- the transmitting the notification relating to detection of the failure is conducted when the relay node operates in EN-DC and the failure in the backhaul link is occurred between the second parent node and the relay node forming the backhaul link with the second parent node.
