Abstract:
The present invention provides a communications method, a communications apparatus, and a base station. According to the method, a base station acquires a start time when a user equipment UE monitors paging information on another network, where a network type of a network on which the UE is located before the start time differs from a network type of the another network, and then, the base station stops scheduling data on the UE in first duration that uses the start time as a starting point, thereby retransmission between the base station and the UE is reduced, and waste of a downlink resource on a network provided by the base station is further reduced.

Abstract:
The present disclosure relates to signal sending and detection methods and apparatus. In one example method, a sending apparatus generates characteristic sequence signals corresponding to a plurality of time division duplexing (TDD) network standards, where the characteristic sequence signals are used for remote interference detection. The sending apparatus sends the characteristic sequence signals in a spatial multiplexing manner.
Abstract:
Embodiments provide a packet processing method. In accordance with this method, a first LSP packet can be received by a network device. The following determinations can be made: that the network device stores no LSP packet whose LSP ID and PDU type are the same as an LSP ID and PDU type of the first LSP packet; that the network device has stored a second LSP packet whose LSP ID is the same as an LSP ID of the first LSP packet and PDU type is the same as a PDU type of the first LSP packet, and that a sequence number of the second LSP packet is less than a sequence number of the first LSP packet. When one or more of these determination are made, a determination whether LSP packet digest information matching the first LSP packet exists can be made. When the LSP packet digest information matching the first LSP packet is determined to exist, the first LSP packet can be stored.
Abstract:
A beamforming-based communication method includes: obtaining cell information; when the cell information meets a preset low-load condition, dividing to-be-processed broadcast messages into a plurality of broadcast message groups; determining, based on a preset correspondence between a broadcast message and a broadcast beam, a broadcast beam group corresponding to each broadcast message group and a broadcast beam for sending no broadcast message in each time window; sending the broadcast message group in each time window by using the broadcast beam group; and shutting down, in each time window, the broadcast beam for sending no broadcast message. Some broadcast beams are used in each time window to send the broadcast message, and the broadcast beam for sending no broadcast message is shut down.
Abstract:
This application provides a data processing method and an apparatus, to detect an interference source, shorten a transmit period and a detection period of a feature sequence, and improve interference detection efficiency. The method includes: determining, by a first base station, a transmit parameter of a first feature sequence based on a first bandwidth and a preset rule, where the first bandwidth is a bandwidth greater than a threshold in a plurality of base stations; and if a frequency corresponding to the transmit parameter of the first feature sequence falls within a bandwidth range of the first base station, sending, by the first base station, the first feature sequence in the bandwidth range of the first base station, so that when receiving the first feature sequence, a second base station determines, based on the first feature sequence, whether the first base station causes interference to the second base station.
Abstract:
A fault root cause analysis method and apparatus are provided. The method includes: obtaining a first alarm event set, where the first alarm event set includes a plurality of alarm events; for a first alarm event in the first alarm event set, extracting a feature vector of the first alarm event, where a part of or all features of the feature vector are used to represent a relationship between the first alarm event and another alarm event in the first alarm event set; and determining, based on the feature vector of the first alarm event, whether the first alarm event is a root cause alarm event. In this application, whether the first alarm event is the root cause alarm event is determined based on a feature vector of the relationship between the first alarm event and the another alarm event, and the accuracy of fault root cause identification is improved.
