Problems solved by technology
[0005] Due to the slow start setting of the mobile network, the amount of service data of the terminal at the beginning of the service is very small. Correspondingly, the available air interface bandwidth predicted by the terminal is very small, and the packet sending rate of the server will be very low. The amount of data is still low, and the actual available bandwidth allocated by the base station to the terminal will be far greater than the available air interface bandwidth predicted by the terminal, resulting in a low utilization rate of the air interface bandwidth

The present invention discloses a method and an apparatus for predicting air interface bandwidth, belonging to the field of wireless communication. The method includes the steps of when a data service starts, determining, according to a current first air interface theoretical bandwidth of a terminal and a preset bandwidth allocation coefficient, a predicted available bandwidth of the terminal in a first period, sending the predicted available bandwidth to a server, when a preset period time point is achieved, detecting an actual service bandwidth of the terminal in a current finished period, adjusting the bandwidth allocation coefficient according to the actual service bandwidth, determining, according to the adjusted bandwidth allocation coefficient and a current second air interface theoretical bandwidth of the terminal, a predicted available bandwidth of the terminal in a next period, and sending the predicted available bandwidth to the server. Through adoption of the method, the user ratio of the air interface bandwidth can be improved.
Description
technical field [0001] The invention relates to the field of wireless communication, in particular to a method and device for predicting air interface bandwidth. Background technique [0002] In mobile communication, a base station communicates with a terminal through an air interface (may be referred to as an air interface for short). The air interface includes multiple wireless channels, and the base station can define parameters such as frequency, bandwidth, access timing, encoding method, and handover mechanism for each wireless channel. [0003] When the terminal communicates with the server through the base station, the terminal needs to periodically report the available air interface bandwidth to the server, so that the server can determine the packet sending rate for sending service data to the terminal based on the available air interface bandwidth. At the beginning of each cycle, the terminal can detect the ratio of the amount of service data received in the previ...
