TD-SCDMA RAN Performance Management

April 1,2008 China Mobile launched a social service testing and trial commercial work. In less than six months from top to bottom within the established, more mature operating system, TD-SCDMA market. Subsequently, China Mobile two, three consecutive TD network construction starts, the network covering more than 200 cities across the country.2009 TD-SCDMA network in the country have been put into commercial use, to achieve the scale of development. After the expansion project in 2010, TD-SCDMA network covers more than 330 cities nationwide, the number of base stations reach 22 million subscribers to reach 20 million, established a relatively complete industrial chain. With the rapid development of network scale and the increasing volume of users on the network performance of TD-SCDMA has put forward higher requirements.Network performance management is to maintain the necessary conditions for sustainable and efficient development, which directly determines the operation of the network quality of service, and how to guarantee network service quality has been the Internet and telecommunications fields to study the hot and difficult, is the extensive development of multimedia communications in the network The core business of one of the foundations.This document focuses on 3G TD-SCDMA mobile communication system, implement performance management programs, the introduction of the TD-SCDMA's technical characteristics and advantages of this basis, the UMTS system structure and RNS within the interface and communication protocol, discussed Network performance management in wireless access part of the TD (RNC and NodeB) of the core software operations and maintenance center OMC (Openation Maintenance Center) to achieve the basic functions of NodeB performance focuses on the management of hardware and software design.According to China's communication industry standards to the NodeB transmitting and receiving equipment performance requirements, introduced NodeB O&M software architecture and performance management implementations, and the NodeB for measuring the performance of each unit of hardware and software implementations, the system described TD NodeB-SCDMA in performance management to achieve the principles and methods.
