Research On Harbin Telecom IPRAN Bearer Network Construction Plan

Nowadays is the era of great information development.Different kinds of communication services have mushroomed.The emergence of various integrated network services has also provided more choices for different user needs.On this basis,the new IP network transmission structure has been Become a major network operators the future development trend.The rapid development of mobile terminals also led to the IP network of mobile networks has become the first network architecture need to complete the construction link.more important part of the mobile network.IP in IPRAN refers to the Internet Protocol,Relative to the traditional SDH transport network,IPRAN means: "wireless access network IP" is a new IP-based transport network.This new network technology is based on the high degree of freedom of the IP communication design concept,based on mature and stable high-quality traditional router structure,has become the majority of mobile operators to build an important solution to carry the network.Its multi-service bearer,access to large-capacity bandwidth,high quality of service(Qos),and the use of enhanced OAM fault detection mechanism for network operation of the business all-round support.The network structure of the hardware structure with flexible three-tier routing capabilities to better serve the existing mobile data services,and comply with the current trend of mobile communications networks,but also can meet a large number of complex business needs.Based on the existing network operation of Harbin Telecom Company and the background and future development of network construction scheme of future carrier network IP,this paper summarizes the current situation of IP network based access technology.Secondly,the main research IP access network operating theory,involving network technology,network theory and application status quo.Then,based on the status quo of IP running network technology,the theoretical knowledge of IP running access is proposed,including the network structure and network scheme of IP running network.Starting from the IP network planning,defined the construction of Harbin Telecom IP network construction.Based on the IP operation technology,a carrier network that meets the requirements of the LTE service is constructed.After the current IP network construction is completed,throughthe independent performance testing of routing equipment and LTE base station service engineering test,the feasibility scheme and network scalability of the IP operation network are verified.Each area network operates stably with good effect and meets the future development Need to upgrade the bearing network.At the same time,in order to meet the centralized configuration requirements of BBUs in existing wireless networks in urban areas,an optimization scheme of IP operation load network is put forward,and the IP operation equipment is placed in the centralized construction scheme.
