[0004] However, for the user terminal to periodically send BSR to the eNodeB, if the period for the user terminal to send the BSR to the eNodeB is small, it will cause a large network overhead. The time interval between the time when the eNodeB sends a BSR and the time when the user terminal sends a BSR to the eNodeB next time is relatively large, which may cause the uplink resources to be quickly allocated by the base station to the user terminal based on the BSR sent by the user terminal last time. The user terminal is used to send uplink data. Since the time interval between two BSR transmissions is relatively large, after all the uplink resources allocated in the current one are used to send uplink data, the user terminal cannot obtain new uplink resources immediately, resulting in the user terminal being unable to Send the data in the uplink buffer to the eNodeB in real time, causing a large delay in uplink data

The present disclosure relates to a buffer status report BSR reporting trigger method, device, and user terminal. The method includes: obtaining the amount of data that the user terminal needs to send reported by the user terminal to the base station; The size of the uplink resource allocated by the user terminal; if the difference between the amount of data and the size of the uplink resource is less than a preset threshold value, trigger the user terminal to report a buffer status report BSR to the base station; when the user terminal When there is a large amount of data to be sent, according to the difference between the amount of data that the user terminal needs to send and the size of the uplink resources allocated by the base station to the user terminal, it can be judged whether to trigger the user terminal to report the BSR to the base station, so that the user terminal does not need to periodically report to the user terminal. The eNodeB sends the BSR, which avoids the problem of large network overhead caused by a small cycle, and also avoids the problem of a large delay of uplink data caused by a large cycle.
Description
technical field [0001] The present disclosure relates to the technical field of intelligent terminal equipment, and in particular to a buffer status report (BSR) reporting trigger method, device and user terminal. Background technique [0002] In Long Term Evolution (LTE for short), a user terminal (User Equipment, UE for short) sends a buffer status report (BufferStatus Report, BSR for short) to an evolved Node B (Evolved Node B, eNodeB for short) to indicate that the user How much data needs to be sent in the uplink buffer of the terminal, so that the eNodeB allocates uplink resources to the user terminal, so that the user terminal can send uplink data to the eNodeB through the uplink resources. [0003] In the prior art, there are many ways to trigger the user terminal to send the BSR to the eNodeB, one of which is that the user terminal periodically sends the BSR to the eNodeB, for example, when the user terminal has a large amount of data to send, the data continuously ...
