For The 3g Ptn Transmission Technology Research

3G networks, wide-generation technology, IP-based and need full-service access to the characteristics of a new generation of transmission network proposed by the new challenge. The direction of development in the wireless network, the world's leading carriers without any intent to select LTE as a post-3G era direction of development. For 3G, service bearerhas undergone tremendous changes in the demand, the existing MSTP and IP technology system are not well adapted for carrying businessneeds.The transmission network is the cornerstone of network communications. This paper describes the development of 3G-oriented transmission, provide a 3G network model of the times; transmission network construction strategy and program design, finally put forward in the protection of existing investment in transport network, based on suggestions on how to improve resource utilization model assumes that given a reasonable solution.
