The invention relates to the field of communication, and discloses a method and a device for evaluating the performance of a system. The method and the device are used for evaluating the performance by dynamic simulation while the static simulation evaluation efficiency is achieved. The method includes evaluating a corresponding relation among static index values and dynamic index values in a dynamic preliminary simulation mode; using dynamic and static interfaces for semi-static simulation; acquiring air-interference performance parameters of UE (user equipment) via output of static simulation; and mapping the air-interface performance parameters to the dynamic and static interfaces according to a certain mapping method to obtain relevant output of dynamic simulation. Accordingly, an effect of evaluating the performance by the dynamic simulation is realized while the static simulation evaluation efficiency is achieved, in other words, time-variant characteristics of a channel and processing gains of a transmission mode and algorithms such as a detection algorithm are embodied via simulation evaluation results on the premise that the simulation evaluation efficiency is improved, the reliability of simulation evaluation for the performance is guaranteed, and processing time required by the simulation evaluation is saved.

technical field [0001] The invention relates to the communication field, in particular to a system performance evaluation method and device. Background technique [0002] At present, when the existing LTE (Long Term Evolution) network planning software is used to evaluate network performance, static simulation or dynamic simulation is mainly used, and static output or dynamic output is directly calculated or mapped to the link curve. Get the estimated performance of the system. Among them, the so-called static simulation refers to: multiple captures of the mobile communication system scene, and the establishment of an ideal system balance point according to the results of each capture, and then statistics of the performance of the system when the ideal balance is reached, simulating the average performance index of the system; The so-called dynamic simulation is a discrete event simulation method, which simulates in a certain cellular network topology, user terminals move a...

Problems solved by technology

[0003] However, the static simulation method and the dynamic simulation method have their own imperfections. The former simulation efficiency is relatively high, but it does not fully consider the time-varying characteristics of the channel and the gains brought by various physical layer algorithms, while the latter is more reliable. accurately reflects the network performance, but the simulation efficiency is low

In view of this, under the existing technology, in the system simulation evaluation, in order to improve the simulation efficiency and the impact on the system performance is within the acceptable error range, technicians expect to be able to design a simulation method that can achieve static evaluation efficiency At the same time to obtain dynamic evaluation performance, however, at present, there is no simulation method that can well achieve the expected goal
