Abstract: A fault localization method and device are provided. The method includes: obtaining user experience data, network topology data, and resource management data that are of a video service; where the network topology data is used to represent a connection relationship between network devices, and the resource management data is used to represent a connection relationship between user equipment and the network devices; determining a quality of experience (QoE) experience indicator of a network device based on the user experience data, the network topology data, and the resource management data; and when quality of experience represented by the QoE experience indicator of the network device is lower than quality of experience represented by a device screening threshold, determining the network device as a possible questionable device. According to the embodiments of the present invention, accuracy of fault localization is high.

Abstract: The embodiments of the present disclosure provide an antenna system, including a barrel directional antenna array, a radio frequency transceiver, and a baseband signal processing and control unit. Based on the barrel directional antenna array, the antenna system can adjust the quantity of sectors in a 360-degree range based on a change in a service volume in the 360-degree sector, so that an adjusted sector service capacity threshold can accommodate the service volume in the 360-degree sector. In this way, resource scheduling flexibility is improved.

Abstract: A method and an apparatus for non-access stratum (NAS) message processing during handover in an evolved network are provided. The method includes the following steps. An evolved packet core (EPC) receives a message which indicates that a UE is being handed over sent by a source evolved NodeB (S-eNB), and stops sending an NAS message to the UE temporarily. The EPC receives a message which indicates that the UE returns to an S-eNB service area sent by the S-eNB. The EPC sends the NAS message to the UE through the S-eNB, if needed. With the method and the apparatus, the EPC can acquire a location of the UE in time in the case of a handover failure of the UE, a time limit of a retransmission timer is set precisely, and a specific implementation for forwarding an NAS message through an X2 interface is provided.

Abstract: The present application provides a dielectric resonator, a dielectric filter, a base station and a method for fabricating the dielectric resonator or the dielectric filter. The dielectric resonator includes: a solid dielectric resonator body, a blind hole located on one side of the solid dielectric resonator body, a metalized layer covering both a surface of the solid dielectric resonator body and a surface of the blind hole, and a demetallized notch located at the metalized layer on the surface of the blind hole. The dielectric resonator provided in the present application can implement tuning of the dielectric resonator, and reduce impact on the resonance frequency of the dielectric resonator after the dielectric resonator is tuned, where the impact caused by that the demetallized notch is covered by a metal material in an assembly process of the dielectric resonator, and signal energy that is leaked from the notch is reduced.
