Research On Planning And Smooth Evolution Of IPRAN Network

The early development of the RAN network (radio access network), is the transport network between the base station controller from the wireless base station.Most of the traditional RAN network is mainly based on MSTP, transmission equipment and other traditional microwave products,is a network based on circuit switching.As everyone knows, the future of mobile is broadband.In the next stage, providing online community, through the mobile terminal online TV, online live sports, online fashion show, online games, online business will be known as possible. All of these operations are meant to have more traffic to each terminal user, more bandwidth is needed.In the future, all information services will be based on broadband, mobile broadband will penetrate into every corner of our life.But if you still use E1 to load the mobile business, cost and bandwidth requirements based on the consideration, obviously the demand can not be meted.Since the IP based mobile network has become the only choice.At present in the communications industry, PTN and IPRAN are two kinds of packet transport network recognition network core technology based on mobile bearing IP..IP RAN is the use of IP technology to replace the traditional transmission network transmission technology RAN network solutions..Both of them can use MSTP, carrier Ethernet, transfer MPLS and IP network..The characteristics of IP RAN is the introduction of IP technology in the Iub interface, the realization of IP Iub transmission interface..This article mainly from the specific business needs, the basic principle and key technology research with IPRAN technology, and as compared with PTN technology, analyzes the advantages and disadvantages of IPRAN technology and the specific implementation plan, and select the pilot city for the actual network test, the feasibility and compatibility of application of IPRAN technology in the concrete network..This paper first summarizes the IPRAN network, and then introduces the basic theory and key technology of IPRAN network, including:MPLS, LDP, FRR, BFD and other mainstream key technology.By choosing a pilot city, complete the planning and construction of the local IPRAN network according to the actual situation, test conditions, and puts forward the corresponding measures to solve the problems in the construction of the network..Finally, the mainstream IPRAN technology and traditional SDH/MSTP technology are compared, and do some research.to how the traditional SDH/MSTP technology to IPRAN network smooth evolution.In this paper, the author combined with application of traditional transmission network, analysis of the application scenarios and various networking scheme of IPRAN technology, and combined with the specific project, from planning, construction to test the whole process of IPRAN technology application,, find out the problems and difficulties may arise and the advantages of IPRAN technology in the specific application, and discuss the application scenarios of different types of tunnel used in IPRAN network, in order to find out the reasonable solution,, and the specific ways to avoid possible risks.This paper combines the current situation and development of business needs of network operators, scenes of various application methods, in-depth study of IPRAN technology, the ultimate success of the IPRAN network is applied to the actual network.. And seek suitable for smoothing operators of traditional SDH/MSTP network upgrade scheme, and make The IPRAN, which is the new mobile bearing network technology can be more widely used in a variety of business scenarios, network level positioning more clearly, network construction investment decreases, the network can expand continuously strengthened.
