先说移动通信系统的组成:主要由移动台、基站子系统和网络子系统组成。基站收发台(BTS)和基站控制器(Base Station Controller)构成了基站子系统。一个完整的BTS包括无线发射/接收设备、天线和所有无线接口特有的信号处理部分。BTS可看作一个无线调制解调器,负责移动信号的接收和发送处理。一般情况下在某个区域内,多个子基站和收发台相互组成一个蜂窝状的网络,通过控制收发台与收发台之间的信号相互传送和接收,来达到移动通信信号的传送。
下面是具体的英文缩写及解释:
BSC(源于话务网管DA分析文档):基站控制器(Base Station Controller) MSC: 是移动交换中心,MOBILE SERVICE SWITCHING CENTER NCC: 网络控制中心 Network Control Center BTS : 全名为:Base Transceiver Station,中文为基站收发台。
参考: The HLR (Home Location Register) is a network database that stores and manages all details of each mobile phone subscriber that is registered in the corresponding GSM core network. Specifically, the HLR is the location register to which an MS identity is assigned for record purposes. The VLR (Visitor Location Register) is a customer database that temporarily stores subscription information for the visiting customers (called roaming). While the VLR holds information on roaming, it holds information on all customers that use the system at the current time including those at home location. The AuC (Authentication Center), commonly a part of the HLR, is a protected database that is used in the security data management for the authentication of subscribers. The secret key used in each SIM card is stored in the AuC.
