cdma2000网络监测系统L1接口协议监测方案研究

Research on L1 Interface Protocol Monitoring Scheme in CDMA2000 Network Monitoring System

以cdma2000 1x EV-DO网络分组域监测系统的开发为研究背景,在学习研究CDMA数字蜂窝移动通信网定位业务L1接口协议的基础上,提出采用哈希(Hash)算法和方法封装等技术实现L1接口协议的监测模块。本监测方案对L1接口协议的解码、呼叫详细记录(CDR)合成等技术进行了详细的描述,并通过现网采集的数据对此监测方案进行测试,达到了预期的效果。

Taking development of CDMA2000 lxEV- DO packet domain monitoring system as research background, and based on study about L1 interface protocol in CDMA Digital Cellular Mobile Telecom- munication Network Location Based Service, hash algorithm and methods encapsulation are put forward to implement the monitoring module of L1 interface protocol. This scheme makes a detailed description about the decoding scheme and CDR synthesis algo- rithm of L1 interface protocol. The scheme has been applied to the CDMA2000 monitoring system for testing. According to the test of network data, it is verified that the test result is correct. The pattern and method of this research have instructional and promotion meaning for other application level proto- cols.
