Abstract
Embodiments of the present disclosure provide a backhaul path switching method, a wireless relay, a network-side node and a terminal. In the embodiments of the present disclosure, a second backhaul path is pre-established, a backhaul path is switched in the case that a radio link fails or signal quality of a related wireless relay does not meet requirements.
Claims17
A backhaul path switching method, comprising:
- determining, by a first wireless relay, that a first backhaul path currently used by a terminal is required to be switched, wherein at least the first backhaul path and a second backhaul path are pre-established for the terminal, each of the first backhaul path and the second backhaul path is from a network-side node to the terminal, the first wireless relay is a relay in the first backhaul path and the second backhaul path, and respective prior-hop relays or respective next-hop relays of the first wireless relay in the first backhaul path and the second backhaul path are different;
- switching a backhaul path currently used by the terminal from the first backhaul path to the second backhaul path.
A backhaul path switching method, comprising:
- determining, by a network-side node, that a first backhaul path currently used by a terminal is required to be switched, wherein at least the first backhaul path and a second backhaul path are pre-established for the terminal, a first wireless relay is a relay in the first backhaul path and the second backhaul path, and respective prior-hop relays or respective next-hop relays of the first wireless relay in the first backhaul path and the second backhaul path are different;
- transmitting, by the network-side node, a notification message to the first wireless relay, wherein the notification message notifies the first wireless relay to switch the backhaul path currently used by the terminal.
