| Entering the 21st century, China telecom industry into a real competitive era. Nowadays, China telecom industry has already been completed restructuring, has also released 3G licences telecom operators as domestic present japan all business competitive situation. The hulunbuir mobile intracity networks through the annual construction and development, the network coverage has a fairly large, light access rate has reached 83.1%. How in the new competition pattern to remain competitive, and even play traditional business strengths, build better transmission network of Hulunbuir mobile is essential in the future, is the competition keep lead key.This thesis mainly to the hulunbuir mobile metro teleportation networks system construction strategy is studied. This paper expounds the present situation of the Hulunbuir mobile transmission network, find the current existing problems in the transmission network. Anaily the technology developments which based on the current transmission network, summarizes the main transmission network technology in the future development direction. According to the hulunbuir mobile transmission network practice, combined with the mobile transmission network construction principle and development strategy, from transmission lines and transmission equipment two aspects, figuring out the future hulunbuir mobile the construction scheme of metropolitan area transport network. Through this paper, which will improve the hulunbuir mobile metropolitan core layer, convergence layer, the access layer three layer of network structure, improve the safety and reliability of the network transmission of metropolitan area transport network in the future the hulunbuir move faster and better, stronger has guiding significance for the development. |
