Mobile Broadband Multi-service Access Network,

21 century is the information era,voice,data,video and multimedia communication service have rapidly become necessary factor of our life and social.And the same time,it put forward higher demand to technology development,capacity increasing,velocity improvement and service multiplicity.With communication rapid development and competition rapid severity,exploring new technology and new service to meet customer' s need becomes one of important goal to the communication corporation.Broad-band multi-service access is one of important content,coming information and communications services in deed via wireless and wire mean.But the station and position of the broad-band multi-service access are not very optimism.Dada service scale is rapidly expanding;transport network band resource is not enough;present network is not fitting dada transfer;technological realization of broad-band multi-service access is complex and all kinds of services are apart in the multi-service demand of market,therefore,the separation is not good for multi-service conformity,sharing and management;it restricts multi-service development for no integration network controllers.In conclusion,it is necessary to build the broad-band multi-service access network with system,intergration,standard and regulation.With building broad-band multi-service access network,it uses all resource advantage of the mobile communication corporation,relies on all kind of access technology,unites network platform,builds access technology stencil and utilizes many standard mode to realize resource valid equipment,cost reducing,capacity ensured and network security of mobile multi-service access to effectual serving to the customer.In a word,with studying enough the wireless and wire broad-band access station and developing trend at present,we will realize broad-band multi-service access network platform planning,adjusting and rebuilding,join wireless access network with data network,and extend the multi-service access network control system according principle of the "chief plan and separating implement".In the end,we will improve our knowledge to the mobile broad-band multi-service access by studying and expecting new technology.
