摘要
說明書
Example Embodiment 49: A wireless access node of a radio access network (RAN) that communicates over a radio interface with a wireless node, the wireless access node comprising: processor circuitry configured to generate at least one reconfiguration message, the at least one reconfiguration message activating a first data path and a second data path, the first data path and the second data path being established between the wireless access node and the wireless node, the second data path being relayed by a wireless relay node; transmitter circuitry configured to transmit the at least one reconfiguration message; receiver circuitry configured to receive a failure information message on the first data path; wherein the failure information message is based on a notification message that the wireless node receives from the wireless relay node, the notification message indicating a radio link failure (RLF) on the second data path.
Example Embodiment 50: The wireless access node of Example Embodiment 49, wherein the failure information message includes a type of failure indicating whether or not the transmission of the failure information message is caused by the notification message.
Example Embodiment 51: The wireless access node of Example Embodiment 49, wherein the notification message includes location information identifying a node on the second data path that detect the RLF, and the failure information message includes the location information.
Example Embodiment 52: The wireless access node of Example Embodiment 49, wherein the notification message includes one or more measurement values of signal strength/quality, and the failure information message includes the one or more measurement values.
