Network optimizing method and network emulation system

Abstract

The invention discloses a network optimizing method and a network emulation system. The network emulation system comprises a network management unit, a radio network controller (RNC), a base station and an emulation transmission terminal, wherein the network management unit is used for controlling the RNC to start a network emulation test for a specified cell; the RNC is used for starting the network emulation test for the specified cell when receiving a network emulation test starting message transmitted from the network management unit, establishing an uplink wireless link for a base station of the specified cell, and starting measurement control for the base station; the RNC is also used for collecting and storing measurement reports submitted by the base station after the measurement control is started; the base station is used for receiving uplink signals of the emulation transmission terminal under the measurement control of the RNC, and measuring, demodulating and decoding the uplink signals to obtain a measurement report and report the measurement report to the RNC; and the emulation transmission terminal is used for transmitting the uplink signals to the base station of the specified cell. Through the network optimizing method and the network emulation system, the accuracy and efficiency of network optimization can be improved.

Description

technical field [0001] The invention relates to a time-division duplex mobile communication system, in particular to a network optimization method and a network hard emulation system. Background technique [0002] Whether it is the second generation or the third generation mobile communication system, it is finally embodied in the form of a mobile communication network, and network optimization is an important part of the mobile communication network. [0003] Usually, network optimization depends on the test terminal, which generates and records relevant data in the coverage area of ​​the mobile communication system through the test terminal, and finally optimizes the network through data analysis, but the signal processing capability and accuracy of the test terminal are limited, and it needs to rely on Due to the existing configuration of adjacent cells, and in actual situations, missing configuration of adjacent cells is common, so the method of using test terminals for ...

Problems solved by technology

[0003] Usually, network optimization depends on the test terminal, which generates and records relevant data in the coverage area of ​​the mobile communication system through the test terminal, and finally optimizes the network through data analysis, but the signal processing capability and accuracy of the test terminal are limited, and it needs to rely on Due to the existing neighbor cell configuration, and in the actual situation, the lack of neighbor cell configuration is common, so the method of using the test terminal to optimize the network has certain limitations

[0004] In addition, network optimization can also use equipment such as frequency scanners. Although this method can partially overcome the problem of missing configurations in adjacent cells, the accuracy of signal measurement is affected due to mutual interference of the same-frequency signals of multiple downlink cells. After the network is partially adjusted, it needs to be re-tested to reflect the new situation of different superimposed signals after the network adjustment, so there are certain limitations

[0005] It can be seen that the accuracy and efficiency of existing network optimization are not high
