Abstract: A device location sensing method obtains locations of N devices in a wireless network based on channel state information (CSI). Each device in the wireless network has M antennas arranged in a non-linear manner. To determine the device locations, CSI data mutually detected between every two devices in N devices is obtained and used to calculate an angle difference of arrival (ADoA) set which includes, for every two devices in the N devices relative to each of the other devices in the N devices, an ADoA that is a difference between angles of arrival (AoAs) of the two devices relative to the other device. Relative locations of the N devices are then calculated based on the ADoA set.

Abstract: A service protection method includes a first node that determines that a fault has occurred on a first working path, and generates a service switching message based on the fault on the first working path. The first node sends the service switching message on a first protection path, where the service switching message indicates to adjust a bandwidth of a service from a guard bandwidth to a target bandwidth, where the guard bandwidth represents a pre-occupied bandwidth of the first protection path before the service is transmitted, where the target bandwidth represents an occupied bandwidth for transmitting the service on the first protection path, and where the guard bandwidth is less than the target bandwidth.

Abstract: Embodiments of this application disclose a packet processing method and a related apparatus. The method includes: A network device receives n first packets sent by a terminal device, where each first packet includes one first sequence number field, and the first packet is an air interface packet. The network device determines a sending sequence of n second packets based on values of first sequence number fields of the n first packets, where each of the n second packets corresponds to one first packet. The network device sends the n second packets to a management platform or an application server based on the sending sequence.

Abstract: A clock port attribute recovery method includes a network device setting a value of a port attribute of a clock port of the network device to a first value based on the clock port not receiving any one of three types of clock messages: N synchronization messages, follow-up messages, and delay response messages within a timeout interval, where the first value indicates that a message is lost on the clock port. Based on a case that a recovery condition is met, the network device sets the value of the port attribute of the clock port to a second value, where the second value indicates that a status of the clock port is that the message is not lost.

Abstract: This application provides an omnidirectional dual-polarized antenna and a communications device. The omnidirectional dual-polarized antenna includes a first printed circuit board, a feeding structure, a feeding strip, and grounding strips. A metal ring structure and a metal disc structure are arranged on the first printed circuit board, and the metal ring structure surrounds the metal disc structure. The feeding structure is perpendicular to the first printed circuit board and connected to the metal ring structure. The feeding strip is perpendicular to the first printed circuit board and connected to a central point of the metal disc structure. The grounding strips are each perpendicular to the first printed circuit board and connected to the metal disc structure. The metal ring structure and the feeding structure form a horizontally polarized unit, and the metal disc structure, the feeding strip, and the grounding strips form a vertically polarized unit.

Abstract: The disclosed apparatuses and methods are directed to data plane restoration in a network. A method comprises receiving a label-switched path (LSP) failure notification indicating a failure in a network; generating, by a node of the network, a fast-restoration (FR) message and transmitting the FR message to a second node of the message forwarding path. The FR message comprises: a plurality of forwarding instruction objects (FIOs) having forwarding instructions for the FR message for each node of a message forwarding path; and a plurality of label-switched path objects (LSPOs) having a restoration LSP data for each node of a protection detour path. Another method comprises receiving the FR message; generating a modified FR message based on the FR message; and transmitting the modified FR message to another node of the message forwarding path based on the FIO, prior to processing the FR message by the node.
