Research On Access Mode Improvement Of Zhengzhou Mobile Group Customer

Since China Mobile Communications Corporation(CMCC)established,wireless voice service has always been the principal means of revenue.With the advent of the era of 3G / 4G,CMCC's advantage of wireless voice service was gradually weakening,According to the existing situation,CMCC must develop its cable business-an area that is not good at,to maintain its sustained and rapid development.CMCC has been developing its own cable business since it acquired the cable business license in 2012.As an important part of the cable business,group customer business has always been an important part of the development of CMCC's cable business.The development of traditional group customer business depends on CMCC's traditional advantages,voice services(mainly large group voice services),and The overall networking situation of Zhengzhou branch.However,with the development of communication technology,the requirements of the group customer are changing constantly about the business' s types and bandwidth,showing the trend of "ALL IP" and high bandwidth.The traditional SDH and MSTP network mode obviously can't adapt to the existing market demand,and the development of PTN network mode is the inevitable demand to group customer business.This paper takes Zhengzhou mobile group customer access network as the research object,discusses the access network in the networking mode of SDH period,and change into the current PTN period of evolution,including the decomposition of single network,the 5 network hybrid network mode.Then this paper combines the existing core aggregation layer with the whole network and the distribution of access nodes in Zhengzhou,ensuring the development of group customer business based on the principle of the development,manageability,operation and appreciation,finishing the design of access layer network model for the present situation of zhengzhou branch's group customer business,including the requirement of networking for special group customers,and different models for different interworking requirements.At the same time,this paper puts forward the framework of group customer access system under different scenarios,and sets up the basic operation and maintenance system needed for the development of customer service.At last,this paper gives the engineering practice of access network design,completed the design of the construction of Sinopec gas station video line project,analyzes the project management and economic benefit,and the further development of group customer business is discussed.
