An analysis method and system for transmission rate of packet service data

Abstract

The invention discloses a packet service data transmission rate analysis method and a system applying the method. The packet field data transmission rate will be affected by wireless environment and various transmission layer parameters. The analysis system of the present invention comprehensively analyzes the source data analyzed by the interface, automatically interprets and analyzes the data, and judges that the specific factors affecting the data transmission rate lie in MAC, RLC, TCP / UDP or in the upper layer protocol data, thereby analyzing Staff can greatly improve the efficiency of cognition of system business characteristics, so as to quickly diagnose system performance and defects. Moreover, according to the characteristics of the packet service protocol stack of the mobile communication system, the system of the present invention performs systematic analysis of multi-interface and multi-protocol layers on the collected source data, automatically generates analysis result database files, corresponding graphics, statistical results and suggested diagnoses, and improves test performance. Analysis efficiency.

Description

technical field [0001] The invention relates to the technical field of testing in mobile communication systems, in particular to a system and method for analyzing packet service data transmission rates. Background technique [0002] The application of packet services to mobile communication systems is the development direction of mobile communication. The packet service applied to the mobile communication system is different from the public Internet because it needs to be used in a wireless environment. To ensure the service quality of its transmission in the wireless environment, the packet service introduces a more complex protocol layer in the wireless access network to ensure transmission. The reliability of various retransmission mechanisms are at the expense of the transmission rate. Therefore, in a mobile communication system, how high a rate of packet services can be supported for a long time has become a key feature of the system. In the protocol layer introduced ...

Problems solved by technology

[0012] 1) The air interface environment is bad, and frame loss causes data retransmission, which leads to a decrease in download data rate;

[0013] 2) Frequent sending of Status packets occupies too much data sending bandwidth, resulting in low data transmission rate;

[0014] 3) The parameters related to the transmission format of the MAC layer are incorrectly configured, resulting in a low transmission rate during the data download process;

[0015] 4) The RLC layer parameter configuration is wrong, resulting in data download interruptions in the RLC layer during the data download process;

[0016] 5) The data transmission of the Iu port stops, resulting in the interruption of data transmission

[0017] Many parameters affect the data transmission rate, but currently there is no special tool to analyze the transmission performance of packet services
