Description

区域转换方法及系统 技术领域 本发明涉及移动通信技术领域， 尤其涉及区域转换方法及系统。 背景技术 目前， 无线通信系统使用电磁波和移动的或者固定的无线通信终端进行 通信。 无线通信信道将电磁波频率分成多个载波频率， 一个载波频率就是一 个无线通信信道。 无线通信系统通过基站 （Base Station, 简称为 BS ) 利用 指定的无线信道在一定地理范围内提供无线覆盖， 这个地理范围称为小区 ( Cell ), 通常，基站位于小区的中央。 终端从一个小区移动到另一个小区时， 为了保持通信， 需要进行基站的切换。 由于通信技术的快速发展， 在传统基站基础上出现了先进基站
( Advanced Base Station, 简称为 ABS ), 先进基站又分为仅支持先进协议的 基站、 同时支持先进协议与传统协议的基站。 对于后者， 其时间区域（Time Zone ) 可以分成两个区域， 第一区域（也称为先进区域） 和第二区域（也称 为传统区域）。 这样， 先进终端 （Advanced Mobile Station, 简称 AMS )工作 在第一区 i或， 传统终端（ Yardstick Mobile Station , 简称为 YMS )工作在第二 区域。 由于先进终端可以釆用最新通信协议或传统协议， 因此， 先进终端既 可以工作在第一区域也可以工作第二区域。 先进终端在第一区域和第二区域 之间的转换称为区域转换 （ Zone Switch )。 先进控制站 （支持 IEEE802.16m 协议的基站 /中继站） 能够兼容支持传 统移动站 （支持 IEEE802.16e 协议的移动站）， 同样地， 先进移动站 （支持 IEEE802.16m协议的移动站） 也能够接入传统控制站 （支持 IEEE802.16e的 基站或支持 IEEE802.16j 的中继站）。 先进控制站的第一区 i或支持 IEEE 802.16m定义的新的通信协议， 又可以称为 16m Zone (简称为 MZone ), 第 二区 i或可以支持 IEEE802.16e/16j 的十办议， 可以称为 Legacy Zone (简称为 LZone )。 才艮据现有技术， 先进基站第一区域的邻区广播消息 （ AAI-NBR-ADV ) 只发送邻区先进基站和邻区先进基站第一区域的系统信息。 先进基站第二区 域的邻区广播消息（ MOB_NBR-ADV )只发送邻区传统基站和邻区先进基站 第二区域的系统信息。 如果工作在先进基站第一区域的先进终端为了获得更 好的服务希望进入服务基站的第二区域工作， 或者希望从第二区域进入第一 区域工作， 按照现有技术， 先进终端无法从先进基站的第一区域的邻区广播 消息中获取当前服务基站第二区域的系统信息， 也无法从第二区域的邻区广 播消息中获得第一区域的系统信息。 在无法获得上述系统信息的情况下， 终 端执行上述区域转换的时延将会增大。 发明内容
