通用分组无线业务GPRS General Packet Radio Service GPRS 在GSM技术的基础上提供的一种端到端分组交换业务 移移动动台台如如何何与与外外部部数数据据网网络络进进行行数数据据传传输输 移动台开机时处于gprs的空闲状态 没有附着到gprs移动管理功能上 无法识别gprs网络 如果想和外部数据网络 进行通信 如发送电子邮件或浏览网页时 这时就要求移动台附着到gprs网络 执行一个pdp上下文激活的程序 然后才进行传输数据 Attach 由ms触发的 ms将IMSI International Mobile Subscriber Identity 附着到gprs业务上 在MS和SGSN service gprs support node 上生成MM上下文 这样就具备进行PDP激活的条件 一般功能 GPRS附着 建立起MM上下文 MM状态转为就绪 GPRS分离 删除MM上下文 MM状态转为空闲 PDP packet data protocol 所谓pdp上下文激活就是移动台要求网络为它分配一个ip 地址 使它成为ip网络的一部分 当pdp激活后就可以进 行数据传输 由ms 发起分组数据业务 当mm状态为idle ms首先执行移动性管理的附着程序 进入mm准备就绪状态 才能执 行PDP上下文的激活程序来实现分组数据业务 PDP上下文状态 激活状态 PDP上下文包含处理分组数据包所需的路由及映射信息 可以进行数据传送 此时的MM状态为standby LA location area 位置区的标识 为了确认移动台的位置 每个GSM 覆盖区都被分为许多个位置区 一个位置区可以包含一个或多 个小区 网络将存储每个移动台的位置区 并作为将来寻呼该移动台的位置信息 对移动台的寻呼是通过对移动台 所在位置区的所有小区中寻呼来实现的 MSC不可能对它所控制区域内的所有小区一起进行寻呼 因为MSC往往 无法处理这样大的寻呼负荷 RA route area MS开开机机后后 Attach到到GPRS 上上 进进行行PDP上上下下文文激激活活 gprs是按路由区进行位置管理的 MCC 移动国家号码 中国 460 MNC 移动网号 识别移动用户所归属的移动通信网 PLMN EIRHLRSMS
