Description

Abnormal terminal equipment detection method and device

Technical Field

The present application relates to the field of communications technologies, and in particular, to a method and an apparatus for detecting an abnormal terminal device.

Background

In a communication system, a base station allocates radio resources to an accessed terminal device (hereinafter referred to as UE for short), so that the terminal device can perform data transmission based on the allocated radio resources to implement services of the terminal device.

However, in a plurality of terminal devices where the base station allocates radio resources, there may be a case where some terminal devices have no service for a long time or are only in a connected state but have no transmission requirement, which results in a decrease in idle radio resources that the base station can allocate for other terminal devices, and eventually, a decrease in the utilization rate of radio resources. Therefore, the base station needs to detect the traffic data volume of the terminal device, stop allocating wireless resources to the terminal device without traffic or connection state, and empty the resources occupied by the terminal device.

Currently, in a detection mechanism of a terminal device, when a base station detects that data sizes of uplink and downlink Buffer Occupancy (BO) of a UE are both 0, a detection timer is started. If the detection timer normally counts and detects that the uplink BO data quantity and the downlink BO data quantity of the UE are not 0, the base station terminates the detection timer. If the detection timer is overtime, when the base station detects that the uplink and downlink BO data amounts of the UE are still 0, as shown in fig. 1, the base station will trigger the random access procedure of the dedicated Preamble (Preamble) of the UE through a physical downlink control channel command (PDCCH Order). If the random access of the UE is successful, the base station requests a core network (Evolved Packet Core, EPC) to release a radio access bearer (Radio Access Bearer, RAB) of the UE, and reports a release reason, namely UE inactivity, to the EPC; if the random access of the UE fails, the base station requests the EPC to release the E-RAB of the UE, and reports the release reason, namely UE loss (UE_LOST), to the EPC.

In summary, when the base station releases the terminal device with both uplink and downlink data amounts of 0 in a short time, the terminal device actually having a service requirement and in a standby state is released at the same time, so that the accuracy of detecting the service data amount of the terminal device is reduced, and the efficient utilization of the base station resource cannot be realized.
