Research On Vehicle-hold Emergency Mobile Communication System Software Design Base On Container

Along with the fast developing of mobile communication, how to realize the flexible covering and optimize the acquired network efficiently has already become a problem which needs to be resolved urgently. The Vehicle-Hold mobile communication system which reflects quickly, deploys conveniently and serves casually offers a great resolution, besides, the design of software system based on the vehicle hardware platform could also affect the performance and quality of the whole vehicle communication system. Now, the software development of the vehicle mobile communication starts at the part and aims at every gateway and server in the distributed system. But the software system has a complex structure, high redundancy of code and bad patulous integration, besides it could neither configure neatly.This project starts with the module structure's analysis of Vehicle-Hold mobile communication system, and it offers a way to design the software of Vehicle-Hold mobile communication system based on container.The container,is a software system mixed with the public code and the private code. The public code ,also called Control Layer, is fixing to control the operation of the container;The private code,its mainly function is to implement the operation of every equipment in Vehicle-Hold System, we called Operation Layer.The container of Vehicle-Hold mobile communication system,with Control Layer and Operation Layer, which is used to resolve the problems happened during the process of Distributed Communication System software developing, for example, how to codes repeated use, shorten the period of development, improve the quality of software and reduce the cost of maintenance, etc.This article is researching about what is following:1.analyze and summarize the software frame of Media Gateway,Signal Gateway,Media GatewayControl, Location Register and other equipments in Vehicle-Hold mobile communication system Through using some technologies of software framework to vertical decoupling and horizontal decoupling in distributed communication software system.2.Reseach the public code and the private code in Vehicle-Hold mobile communication system after decoupled , combinate the public code together as the Control Layer, analyze characters of the private code, design relevant manage unit which is interface keyword of Control Layer and Operation Layer, is used to resolve the problems of running different functions software in same public circumstance or running different functions multi-software in same circumstance.3.Reseach the Rate Monotonic Algorithm, use the reference of the static mission scheduling algorithm's model and thoughts, design the Block Scheduling Algorithm based on a popedom which can be adaptted to the container. The Scheduling Algorithm allot the popedom to decide who can engross the processor, to resolve the problem of the top limit and the problem of processor use in vehicle mobile system container's integration subsystem.
