Problems solved by technology

3G, LTE and the future IMT-Advanced system provide a possibility to realize this development goal, and sufficient service performance test is a necessary stage to ensure the smooth application of this service, so a set of broadband mobile Objective, fair and reasonable test methods for communication systems (3G, LTE and future IMT-Advanced systems) are a very important task, but there are no specific test methods and devices in this regard
[0004] Although the tests related to the physical layer and the link layer, such as the coverage test and transmission test of the 3G and LTE systems, are relatively mature, the standards for the performance test of the network layer and the service performance test are still in the stage of continuous improvement

Abstract

The invention discloses a system and a method for testing the network performance of distributed broadband mobile communication. The system comprises a base station, users, a geo-synchronous satellite and at least two test devices, wherein the base station is connected to a broadband mobile communication network through an interface; the users communicate with the base station through the broadband mobile communication network; a global positioning system (GPS) receiver is arranged in each test device to realize clock synchronization with the geo-synchronous satellite; the base station is connected with one test device, and the users are also connected with one test device; the test device which is connected with the base station is known as a base station test device, and the test device which is connected with the users is known as a user test device; the base station test device and the user test device are respectively used for transmitting and receiving or receiving and transmitting test information; and test data comprise the test data and geographic information. The system and the method are suitable for testing various network types, and behaviors of the users can be really simulated, so that the network performance and the service performance of the broadband mobile communication can be tested and evaluated.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and relates to a network performance testing device and method, in particular to a distributed broadband mobile communication network performance testing system and testing method. Background technique [0002] With the commercial operation of the third-generation mobile communication network (referred to as 3G) and the gradual maturity of LTE technology, countries around the world have turned to the research of the next-generation mobile communication system (abbreviated as IMT-Advanced). In the low-speed mobile environment, it provides users with wireless transmission capabilities with a peak rate of 100Mbps and 1Gbps. [0003] Network performance testing is very important for 3G and LTE systems. Similarly, it is also the focus of research for IMT-Advanced systems. One of the important driving forces for the development of broadband mobile communication systems is faster and lar...
