通信行业术语、缩略语4A是指：认证Authentication、账号Account、授权Authorization、审计Audit，中文名称为统一安全管理平台解决方案。
即将身份认证、授权、审计和账号（即不可否认性及数据完整性）定义为网络安全的四大组成部分，从而确立了身份认证在整个网络安全系统中的地位与作用。
AUIAUI:Attachment Unit Interface 连接单元接口AUI 端口是用来与粗同轴电缆连接的接口，它是一种"D"型15针接口，这在令牌环网或总线型网络中是一种比较常见的端口之一。
路由器可通过粗同轴电缆收发器实现与10Base-5网络的连接，但更多的是借助于外接的收发转发器（AUI-to-RJ-45），实现与10Base-T以太网络的连接。
当然也可借助于其他类型的收发转发器实现与细同轴电缆（10Base-2）或光缆（10Base-F）的连接。
这里所讲的路由器AUI接口主要是用粗同轴电缆作为传输介质的网络进行连接用的，AUI 接口示意图如图所示。
BNCBNC接头，是一种用于同轴电缆的连接器，全称是Bayonet Nut Connector（刺刀螺母连接器，这个名称形象地描述了这种接头外形），又称为British Naval Connector（英国海军连接器，可能是英国海军最早使用这种接头）或Bayonet Neill Conselman（Neill Conselman刺刀，这种接头是一个名叫Neill Conselman的人发明的）。
BNC接口即常说的细同轴电缆接口。
BNC接头可没有被淘汰，因为同轴电缆是一种屏蔽电缆，有传送距离长、信号稳定的优点。
目前它还被大量用于通信系统中，如网络设备中的E1接口就是用两根BNC接头的同轴电缆来连接的，在高档的监视器、音响设备中也经常用来传送音频、视频信号。
BRASBRAS (Broadband Remote Access Server)宽带接入服务器（Broadband Remote Access Server,简称BRAS）是面向宽带网络应用的新型接入网关，它位于骨干网的边缘层，可以完成用户带宽的IP/ATM网的数据接入（目前接入手段主要基于xDSL/Cable Modem/高速以太网技术（LAN）/无线宽带数据接入(WLAN)等），实现商业楼宇及小区住户的宽带上网、基于IPSec（IP Security Protocol）的IP VPN 服务、构建企业内部Intranet、支持ISP向用户批发业务等应用。

这两天在看MDCN网络系统的时候，碰到很多很多的术语，为了对这个MDCN 系统有进一步的了解，于是每碰到一个术语就百度一下，再一次让我感觉到，百度真是好东西，因为不只是百度到我直接想要的东西，还间接百度到我更加想要的知识。
现在把这两天我看到的、我学到的和我暂时没有用到的一些移动通信术语跟大家分享一下，也许你现在用不着，但只要你身在移动，你还是有可能碰到的。
这些术语肯定不是很全面的，欢迎大家补充啊！AAAA：鉴权、认证、计费AAS：自适应天线系统AIE：增强互联演进AMR：自适应多速率API：应用程序接口AR：接入路由器ASON：自动交换光网络AUC：鉴权中心BB3G：后3GBG：边界网关BGP（Border Gateway Protocol，边界网关协议）BHSM：忙时短消息BICC：承载独立的呼叫控制BITS：大楼综合时钟系统BPSK：二进制相移键控BSC：基站控制器BSS：基站子系统BTS：基站CCAMEL：移动增强逻辑的客户化应用CDMA：码分多址接入CMPP：中国移动点对点短消息CG：计费网关CGI：小区全球标识号CMIP：公共管理信息协议CN：核心网络CORBA：公共对象请求代理体系结构COTS：使用现货CRBT（Coloring Ring Back Tone）多彩回铃音业务（彩铃）CSS：核心网子系统CR：提交报告CS：电路交换CSD：电路交换数据DDCS（Data Center System）数据缓存中心DHCP：动态主机配置协议DSMP：数据业务管理平台DWDM：密集波分复用DXC：数字交叉连接EEAI：企业应用集成EDGE：GPRS演进的增强数据E-OTD：增强型观测时间差分ETOM：增强电信运营视图FFCAPS：故障、配置、计费、性能、安全FDD：频分双工FDMA：频分多址接入FR(Frame Relay): 帧中继GGIS：地理信息系统GGSN：网关GPRS支持节点GMLC：网关移动位置中心GMSK：高斯调制相移键控GMSC：网关移动交换中心8PSK：8进制相移键控GPRS：通用分组无线业务GRE:通用路由封装(Generic Routing Encapsulation)HHA High Availability 高可用HDR：高数据速率HLR：本地位置登记器HSDPA：高速下行分组接入HSTP：高级信令转换点HSUPA：高速上行分组接入IIDS Intrusion Detection Systems 入侵检测系统IN：智能网IMS：多媒体子系统IRP：综合参考点ISMG 短信网关ISMG全称Internet Short Message Gateway IP：智能外设ISIS分级的链接状态路由协议ISO：互联网标准化组织IVR：交互式语音响应ITU；国际电信联盟JKKVM：Kjava虚拟机LLB Load Balance 负载均衡LCS：位置业务LLC：逻辑链路控制LMDS：Local Multipoint Distribution Services本地多点分配系统LSTP：低级信令转换点LTE：长期演进MMDCN移动数据通讯网Mesh：无线网状网络multicast组播MGCP：MGW：媒体网关MIDP：移动信息设备描述MIMO：多入多出MMS：多媒体消息业务MMDS：Multichannel Muitipoint Distribution Service城域多点分配系统MPLS(Multi-Protocol Label Switching) 多协议标记交换MSC：移动交换中心MSTP：多业务传送平台NNAS：网络接入服务器NC2：网络操作模式2NEF：网元功能NGOSS：下一代运营支撑系统NTP：网络授时服务NodeB ：节点B（3G基站）OOAM -- Operation Administration and Maintenance OADM：光分插复用OFDM：正交频分复用OMA：运营商融合组织OSA：开放业务架构OSI：开放标准互联OTA：空中下载OTN：光传送网络OXC：光交叉连接PPBCCH：分组广播公共信道PCCCH：分组公共控制信道PCU：分组控制单元PDTCH：分组数据业务信道PIM：号码管家PON：无源光网络PS：分组交换QQOS：业务质量QPSK：四进制相移键控RRADIUS：用户认证服务器RANAP：无线接入网络应用协议RNC：无线网络控制器RNS：无线网络子系统SSAE：业务架构环境SCE：业务生成环境SCP：业务控制平台SDH：同步数字结构SGSN：服务GPRS支持节点SID：共享信息数据SIGTRAN：信令转换SIP：会话发起协议SLA：服务等级协议SMLC：服务移动位置中心SMAP：业务管理接入平台SMD：业务管理平台SMP：业务管理平台SMPP：短消息点对点协议SMSC：短消息交换中心SNMP：简单网络管理协议SONET：同步光网络SOG：业务运营网关SRF：辅助资源功能Sso Single sign-on单点登陆SSP：业务交换平台STK：SIM卡工具包TTCC：发射合成单元TDD：时分双工TDMA：时分多址接入TD－SCDMA：时分－同步码分多址接入TMSC：二级业务汇接中心（移动）汇接移动交换中心，主要就是省局之间的交换（中国的省较大，如果是一些小的国家的话，那TMSC就是国家与国家之间的交换局了）TMN：电信管理网络TR：二级业务汇接中心（移动）UUAP：统一应用平台UE：用户设备UL-TOA：上行链路－到达时间UMTS：通用移动通信系统UniCast 单播USSD：非结构化业务数据UTRAN：UMTS陆地无线接入网络Uu接口：空中接口VVC：充值中心VLR：拜访位置登记器VPMN：虚拟专用移动网络VPN：虚拟专用网VMSC：当前移动交换中心WWAP：无线应用协议WCDMA：宽带码分多址接入WDM：波分复用WiMAX：无线互联微波接入WLAN：无线本地接入网络WMAN：无线城域网WSP：无线会话层协议WTBS：移动WAP类第三方业务(简称WAP业务)支撑系统WTCP：无线事务控制协议XXDSL：扩展数字用户线。
