Research And Application Of Virtual Network Environment Test System In TD-LTE Network

With the advancement of science and technology,the role of mobile internet in people's daily life is increasingly important.All mobile applications require a well-covered,high-speed communications network.With the gradual increase of users,the scope of cities has gradually expanded,and communication networks have become more and more complicated.In order to better build communication networks and better optimize communication networks,network environment testing is particularly important.This article is mainly based on the LTE network,aiming at Heilongjiang Mobile's virtual network environment testing system set up to reduce personnel workload and improve testing efficiency,in order to achieve the simulation test effect that “everyone is a network tester”.The system combines the data such as test reports periodically transmitted from the user terminal to the base station and the user positioning data,and reflects the network quality as close to the actual situation as possible after screening data from the huge data pool through different rules.It is reflected through the graphical interface.On the map and work parameters layer,simulation field optimization testing process,to achieve virtual testing.This system uses the virtual test data to invert the network environment so that the optimizer can directly understand the network environment of the user's area(roads,buildings)in the background and analyze the network quality of all subsidiaries of Heilongjiang Mobile for network construction and optimization.in accordance with.
