Embodiments of this disclosure include a packet forwarding method and device, and a related system, and belong to the field of communication technologies. In the method, a first node first receives a route to a destination node sent by a second node, where the route carries an identifier of the second node and a plurality of tunnel attributes. A plurality of tunnels from the first node to the second are in a one-to-one correspondence with the plurality of tunnel attributes. The first node forwards packets with different packet attributes destined for a same destination node through different tunnels. By having the packets with the different packet attributes forwarded over the different tunnels, traffic steering is implemented at a routing layer, and a flexibility of performing the packet forwarding is improved.

Packet forwarding method and device, and system

A channel latency determining method, a positioning method, and device, the method including obtaining, by a communications device, device location information of a calibration user equipment (UE), calculating a propagation delay according to the device location information and prestored location information of an antenna, where the propagation delay is a time between transmitting a radio signal by the calibration UE and receiving the radio signal by the antenna, calculating a time of arrival according to the radio signal transmitted by the calibration UE to the antenna, where the time of arrival is a time obtained through calculation according to a time of arrival (TOA) estimation algorithm, and determining a channel latency according to the propagation delay and the time of arrival, where the channel latency is positively correlated with the time of arrival and is negatively correlated with the propagation delay.
