The Design And Implementation Of IFC Intelligent Entire Frequency Distribution System

With the rapid development of 2G, 3G, 4G communication and WLAN business, the number of mobile users is continuously increasing, Traditional network optimization schemes have not met the requirements of network capacity and performance. this thesis investigates a new solution of indoor network coverage optimization, which is IFC intelligent entire frequency distribution system. The system can cover the 2G, 3G, 4G network and flexibly access the WLAN and fixed broadband signals simultaneously by using the hierarchical architecture, intermediate frequency transmission,broadband digital radio frequency and the remote power supply technology. It not only enhances the network and service quality, but also absorbs indoor and outdoor traffics.This thesis mainly studies the design and implementation of the software system of IFC intelligent entire frequency distribution system, specific works are as follows:Firstly, the south interface communication protocol, function and technical requirements of the interface are made particularly according to the Repeater Network Management interface technical requirements and the Fiber Distributed System Network Management Interface Technical requirements, based on CPRI protocol master and slave device communication is also proposed.Secondly, the monitoring terminal software system is designed on ARM9 and Linux-based embedded development platform by using modular design concept and hierarchical modular software architecture according to the embedded system software architectures and monitoring system requirements. Thirdly, the B/S architecture-based monitoring network management center is designed by adopting the latest J2 EE technology, the SMS text information format of the SMS network management is also briefly designed. Finally, the joint debugging between monitoring center and monitoring terminal has been executed and realized the data communication in the IFC system equipment, monitoring terminal and remote monitoring center, the monitoring system of IFC intelligent entire frequency distribution system is constructed completely.
