Design And Realization Of Data Acquisition And Analysis Platform Based On Mobile Internet

In recent years, with the rapid development and widespread application of the third generation mobile communication system network, various kinds of packet data service have been widely used. In current3G network, the ratio of packet data service has surpassed that of regular telephone service in variety, market and flow. As packet data service occupies a high proportionin UMTS network, its data request and response can reflectthe overall performance of the network perfectly.This dissertation made a research in acquisition and analysis of the wireless packet data in the UMTS network. This dissertation also researched in the realization of signaling analysis platform. Based on the load bearing principle of packet data service in UMTS network, this dissertation designed and realized a data collection and analysis platform in mobile Internet using Iu-PS interface. First, this dissertation introduced the network architecture and interface protocol of3G communication system, the Iu-PS interface was selected as the object to be analyzed after a discussion of data analysis requirement and network interface function. Second, combining the resource data, this dissertation designed and realized a collection and analysis platform based on the control plane of layering model.The main functional modules include signaling collection module, signaling resolving module and flow combing module. Moreover, as real-time collection and analysis can produce large interface flow, we used memory pool and FIFO storage to improve the processing efficiency of the platform. The flow reductive results are stored through the combination of database storage and file storage. Finally, network performance and service quality were evaluated. As the evaluation data was originated directly from the network, the quality evaluation could be more accurate, scientific and comprehensive.
