Mobile bearer network is faced with a comprehensive construction and renovation

an evolution from circuit domain to packet domain. Full installation of 3G networks has brought massive source of growth in the business

which is the driving force of promoting a comprehensive reform of metro transport networks. This paper focuses on the important position of the packet transmission network equipment in the mobile bearer network and the network deployment program based on PTN. It also puts emphasis on making the openness of the intelligent features and the use of software tools meet the PTN network planning and deployment

that is

using scientific and effective projects to implement the design and upgrading to achieve network convergence

service convergence and carrier convergence.
