Problems solved by technology
However, the antenna module of the base station is not very sensitive to uplink data verification, which can easily lead to continuous uplink CRC errors, resulting in the UE being unable to access the base station for normal communication; in addition, when the channel quality of transmitted data changes greatly, often It is difficult to recover even if the uplink CRC gets continuous errors and the channel quality gets better. The impact will last for tens of seconds.
Therefore, the result obtained by the base station detecting the link of the abnormal UE is inaccurate

The embodiment of the invention provides a method and a device for detecting abnormal terminal equipment. In the method, a base station determines that a receiving power value for receiving a sounding reference signal (SRS) of target terminal equipment is smaller than a preset power value and an uplink bit error rate of a wireless frame reaches a set threshold value before a set time; and the base station obtains the uplink bit error rate and the downlink bit error rate of the target terminal device within a set time, and determines the target terminal device as an abnormal terminal device according to the uplink bit error rate and the downlink bit error rate. According to the method, after the fact that the uplink communication quality of the target terminal equipment is poor is preliminarily determined by receiving the SRS power value and the uplink error rate of the target terminal equipment, the abnormal target terminal equipment is determined by further integrating the uplink transmission quality and the downlink transmission quality, and therefore the accuracy of detecting the abnormal terminal equipment is improved.
Description
technical field [0001] The present application relates to the field of communication technologies, and in particular to a method and device for detecting abnormal terminal equipment. Background technique [0002] In a communication system, after a radio resource control (Radio Resource Control, RRC) connection is established between a base station and a terminal device (hereinafter referred to as UE), the base station will allocate radio resources for the UE, so that the UE can perform data processing based on the allocated radio resources. Transmission to realize the service of the terminal equipment. [0003] However, among multiple UEs allocated radio resources by the base station, some UEs may be blocked or malfunction, resulting in abnormal data transmission links of the UEs, and the UEs cannot perform normal uplink and downlink data transmission. However, in this case, the base station may still retain the access stratum context information (AS context) of the UEs wit...
