| To satisfy a wide spectrum of needs for mobile users,mobile operators make the wireless network systems remain stable and have satisfying performances through network optimization. With the coexsistence of2G,3G and the coming new LTE network, network optimization is filled with chanllenges and also becomes a more complicated work.Wireless-Network test is a key part of network optimization.Drive test sfotware is often uesd as the run method of wireless-network test.Data decoding and processing is a core functionality in this system,it works with network test devices in many types to collect parameters and indicators,or trace the signaling messages.This paper describe a design of a data decoding and processing module which applied in a wireless network test software. The decod module used a three-layer structure (SDK-CommonDeocderLibrary-DeviceDecoderLibrary) to implement the separation of the functional body, its design helps reduce the difficulty of the development and makes it possible to add or remove decoders for specific devices rapidly in this system. Moreover, data denotation trees sharing, delayed decoding for some data collection and other methods are used to lift efficiency in the data decoding process.This module has been verified and shown its effectiveness in practical network testing. Data generated by the network testing device can be decoded rapidly and completely, and processed in different ways to work with other modules in system for analysising network quality.This module are also proven to adapt to different models of test device automatically. |
