Description
Technical Field
The invention relates to the technical field of communication, in particular to a terminal service peak rate debugging system.
Background
With the popularization of the 5G market and the remarkable increase of mobile phone users, the speed and stability of communication services between the mobile phone and the base station are particularly important. How to make the mobile phone traffic rate reach the peak rate and keep stable is a matter of great concern. Especially in the performance test, it is difficult to debug the peak rate, which takes much time and is difficult to realize a proper and stable peak rate.
The peak rate is debugged between the base station and the terminal through drive test software, and the commonly used debugging method at present is as follows:
1. first, the base station output reference signal power is ensured to be a proper value. If the output reference power is too large, signal distortion is caused, and signals larger than the processing threshold of the physical layer processor are processed during signal processing. Here, the uplink and downlink of the 5G Reference Signal are mainly DMRSs (Demodulation Reference Signals), and the downlink of the 4G Reference Signal is mainly CRS (Cell-specific Reference Signals). Meanwhile, the maximum transmitting power of the cell is set to be a proper value, and mutual interference between the cell and the adjacent station is prevented.
2. The signal strength of the main antenna and the auxiliary antenna must be adjusted to be consistent from the perspective of the physical layer, so that the terminal can stably execute the service in the transmission mode only when the main antenna and the auxiliary antenna are consistent in sending and receiving of the main signal and the auxiliary signal. If one path of signal is extremely poor, a pit can be dropped. The two paths of signals need to keep consistent in strength by adjusting attenuation so as to eliminate the phenomena of peak rate difference and pit dropping.
3. The BLER (Block Error Rate) is adjusted. Subject to the limitation of the target BLER, the higher the BLER, the lower the MCS (Modulation and Coding Scheme) and the worse the rate. If the BLER is high, it indicates that the current radio channel environment is poor. If the uplink and downlink BLER is not 0, the angle and position of the terminal and the antenna need to be adjusted repeatedly, so that the BLER is eliminated only after the terminal sends and receives the main and auxiliary signals constantly.
The existing peak rate debugging method needs manual debugging of base station configuration, adjustable attenuation and the angle and position of a terminal, and is time-consuming, labor-consuming and easy to make mistakes. If a certain flow has a problem, the peak speed cannot meet the requirement, and debugging personnel need to call back again, so that the waste of human resources is caused.

the control terminal is used for adjusting the uplink expected power of the base station so that the service rate of the debugging terminal reaches a first service peak rate;
and a terminal service peak rate debugging program is installed on the control terminal. After the debugging terminal accesses the cell of the base station, the debugging of the service peak rate can be carried out. The debugging terminal can be a mobile phone. The debugging program automatically adjusts the uplink expected power of the base station.

The 5G modulation modes comprise QPSK, 16QAM, 64QAM and 256QAM, and the higher the modulation level is, the higher the peak speed can be, the values are 0-27.
In order to reduce the influence of the environment on the signal quality, the MCS of the base station is set to the maximum modulation level, that is, the value is 27, and then the traffic peak rate of the debug terminal is acquired.
And under the condition that the fourth service peak rate is greater than a second preset threshold value, adjusting the MCS of the base station to be in a self-adaptive mode.
