Problems solved by technology

[0020] It can be seen from the above process that the evaluation modeling in the prior art is only applicable to some specific system environments or network elements, but not applicable to other network elements or system environments. Therefore, the applicability of the existing evaluation modeling is relatively low. Poor; on the other hand, the existing evaluation modeling does not combine the type of subframe and the current evaluation link to carry out the corresponding evaluation process, so the accuracy is poor

Embodiment Construction

[0115] Embodiments of the present invention provide a method and system for determining LTE system performance, so as to improve the accuracy and comprehensiveness of evaluating LTE system performance. The method for determining the performance of the LTE system is as follows: according to the preset feature type and configuration parameter combination, determine the configuration parameter combination corresponding to the current feature type, and initialize the determined configuration parameter combination; For each subframe in a radio frame, perform the following operations: update the positions of all users in the LTE system and corresponding timers according to the initialized configuration parameter combination; when the current subframe is a downlink subframe and the current evaluation of the downlink When the link is on, execute the set downlink evaluation process; when the current subframe is an uplink subframe and the uplink is currently evaluated, execute the set up...

Abstract

The invention discloses an LTE (long term evolution) system performance determining method and an LTE system performance determining system. The LTE system performance determining method includes: determining configuration parameter combination corresponding to current ground feature types according to preset corresponding relation between the ground feature types and the configuration parameter combination, and initializing the determined configuration parameter combination; executing the following operations to each subframe of each radio frame in the LET system: updating positions of all users and corresponding timers in the LTE system according to the initialized configuration parameter combination; executing downlink evaluation procedures when the current subframe is a downlink subframe and a downlink is evaluate currently; and executing uplink evaluation procedures when the current subframe is an uplink subframe and an uplink is evaluated currently.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and system for determining the performance of an LTE (Long Term Evolution, long-term evolution) system. Background technique [0002] At present, when evaluating the performance of the LTE system, the method of system simulation modeling is basically used to establish a corresponding model for each network element and system environment in the wireless communication system, and through the simulation test of the model to complete each network in the network. Evaluation of performance indicators. At present, since different network elements or system environments pay attention to different parameter contents, a model suitable for each network element or system environment is established for different network elements or system environments. Currently, the typical evaluation modeling can be done through figure 1 The flow shown is shown, and the flow includes the followin...
