以下以 IEEE802.16标准为例来进行进一步描述。 IEEE802.16标准是针对 微波频段提出的一种新的空中接口标准， 其制订了物理层（PHY )和媒质接 入控制层（Media Access Control, 简称为 MAC )的规范。 IEEE802.16标准中 包含中继结构的 IEEE802.16m是目前最新的标准技术， IEEE802.16m建立在 IEEE802.16e、 IEEE802.16j 等旧标准的基础上。 全球微波接入互通（World Interoperability for Microwave Access,简称为 WiMAX )是一项基于 IEEE802.16 标准的宽带无线接入城域网技术（Broadband Wireless Access Metropolitan Area Network ) 。 在本文中所说的高级技术可以是 IEEE802.16m的 WiMAX 通信系统。
基于以上描述， 高级控制站（支持 IEEE802.16m协议的基站）可以设置 为仅支持高级移动站（支持 IEEE802.16m协议的移动站） ， 或者同时支持传 统移动站（支持 IEEE802.16e协议的移动站）和高级移动站（支持 IEEE802.16m 协议的移动站） 。 高级移动站（支持 IEEE802.16m协议的移动站）也应该能 够接入传统控制站（支持 IEEE802.16e的基站） 。 第一区域（也称为高级区 域， 16m zone , 简称为 MZone )支持 IEEE 802.16m定义的新的通信协议， 即 第一通信协议， 第二区域（也称为传统区域， Legacy Zone, 简称为 LZone ) 可以支持 IEEE802.16e的协议， 即第二通信协议。
在无线通信系统中， 为了保证服务连续性， 移动站在移动过程中往往需 要在不同的控制站之间进行切换。 实现切换的先决条件是移动站进行网络拓 朴的获取和测量， 具体地， 由控制站发送网络的拓朴信息， 为移动站提供相 邻控制站的情况， 移动站对相邻控制站进行测量并上报。 在支持不同标准的 控制站共存的环境下， 控制站发送邻区信息时会根据不同的情况发送不同的 邻区信息。 如传统控制站通过邻区消息（ MOB— NBR-ADV )仅发送相邻传统 控制站信息； 而同时支持两种通信协议的高级控制站可在传统区（ LZone )通 过 MOB— NBR-ADV 消息发送相邻传统控制站信息， 通过先进邻区消息 ( AAI NBR-ADV )发送相邻高级控制站信息， 同时指示有相邻传统控制站 的存在； 对于仅支持第一通信协议的高级控制站， 通过 AAI— NBR-ADV消息 发送相邻高级控制站的信息， 如果周围有相邻的传统控制站， 指示有相邻传
统控制站的存在。
对于移动站从高级控制站切换到传统控制站的情形， 移动站无法通过
AAI NBR-ADV消息获取相邻传统控制站的信息， 而由移动站对相邻控制站 进行扫描获取相邻传统控制站的信息。 在没有相邻传统控制站扫描相关信息 的情况下， 这种扫描效率很低， 需要尝试多次才能获取到相邻传统控制站的 信息， 从而增加移动站切换延迟和接入开销。

本发明的较佳实施方式
在实际系统中传统控制站跟高级控制站相比， 其部署大都比较固定， 数 目也相对较少。 基于这种现象， 本发明提出：
仅支持第一通信协议的高级控制站向移动站发送邻区信息， 所述邻区信 息包含所述高级控制站相邻的支持第二通信协议的控制站的信息；

下面结合附图及具体实施例对本发明进行详细说明。
实施例一
在 WiMAX通信网络中， 随着标准的发展和基站的升级， 系统中会同时 存在釆用不同标准的基站， 如图 1所示， 高级控制站和传统控制站会在无线 通信系统中同时并存。
本实施例中， 移动站主动请求服务控制站发送相邻控制站的信息， 通过 本方法， 移动站可以根据需要获取控制站的邻区信息， 从而改善无线通信系 统移动站切换的性能及降低系统开销
如图 2所示， 本发明实施例包括如下步骤：
步骤 201 , 移动站向高级控制站发送携带请求类型字段的包含部区请求 信息的消息， 请求所述高级控制站发送相邻的仅支持第二通信协议的传统控 制站的信息， 和 /或支持第一通信协议和第二通信协议的高级控制站的信息； 步骤 202, 所述高级控制站接收到所述包含部区请求信息的消息后， 将 邻区信息发送给所述移动站， 所述邻区信息包含移动站请求类型的相邻控制 站的信息。
其中， 移动站向高级控制站发送包含部区请求信息的消息， 可能是由于： 移动站获取到指示仅支持第二通信协议的相邻控制站存在的指示信息； 和 /或所述移动站需要从当前服务控制站切换到其它控制站， 但没有找到可切 入的与当前服务控制站同类型的其他相邻控制站。
优选地， 所述高级控制站通过系统预配置或从自组织服务器获取相邻控 制站的信息， 通过邻区消息或其它消息将所述邻区信息发送给所述移动站。
优选地， 如果有多个移动站同时请求指定类型的相邻控制站的信息， 控 制站将包含指定类型的相邻控制站的信息的消息统一发送给移动站。
下面以具体应用实例进一步描述：
应用实例 1
当移动站从仅支持第一通信协议的高级控制站的覆盖区域逐渐移动到传 统控制站的覆盖区域时， 移动站检测到当前服务高级控制站的通信质量越来
越差并且扫描不到其他相邻的高级控制站或相邻的其他高级控制站都暂时处 于不可接入状态。 与此同时， 移动站根据当前服务高级控制站发送的广播消 息得知附近有相邻的传统控制站。 为了实现切换， 移动站发送包含部区请求 信息的消息给服务高级控制站， 并设置请求类型为传统控制站。 服务高级控 制站收到该包含邻区请求信息的消息后， 将相邻传统控制站的信息通过邻区 消息单播发送给移动站。 移动站获取到包含相邻传统控制站的邻区消息后， 对相邻传统控制站发起扫描和测量， 并切换到合适的相邻传统控制站。
应用实例 2
当移动站从仅支持第一通信协议的高级控制站的覆盖区域逐渐移动到传 统控制站的覆盖区域时， 移动站检测到当前服务高级控制站的通信质量越来 越差并且相邻的高级控制站都暂时处于不可接入状态。 与此同时， 移动站根 据当前服务高级控制站发送的广播消息得知附近有传统控制站。 为了实现切 换， 移动站发送包含邻区请求信息的消息给服务高级控制站， 并设置请求类 型为传统控制站。 服务高级控制站收到一个或多个发自不同移动站的请求相 邻传统控制站信息的包含邻区请求信息的消息后， 将相邻传统控制站的信息 通过邻区消息或其他消息广播发送给移动站。 移动站获取到包含相邻传统控 制站的邻区消息后， 对相邻传统控制站发起扫描和测量， 并切换到合适的相 邻传统控制站。
应用实例 3
当移动站从仅支持第一通信协议的高级控制站的覆盖区域逐渐移动到传 统控制站的覆盖区域时， 移动站检测到当前服务高级控制站的通信质量越来 越差并且相邻的高级控制站都暂时处于不可接入状态。 而根据当前服务高级 控制站发送的广播消息得知附近有传统控制站存在。 在此之前， 移动站曾请 求获取过相邻传统控制站的信息， 则移动站直接根据保留的相邻传统控制站 信息对周围相邻传统控制站进行扫描和测量， 并切换到合适的相邻传统控制 站。
应用实例 4
当移动站从仅支持第一通信协议的高级控制站的覆盖区域逐渐移动到其 他控制站的覆盖区域时， 移动站检测到当前服务高级控制站的通信质量越来 越差。 为了实现切换， 移动站发送包含部区请求信息的消息给服务高级控制 站， 并设置请求类型为请求仅支持第二通信协议的传统控制站和 /或同时支持 第一通信协议和第二通信协议的高级控制站。 服务高级控制站收到该包含部 区请求信息的消息后， 将仅支持第二通信协议的传统控制站和 /或同时支持第 一通信协议和第二通信协议的高级控制站的信息通过邻区消息单播发送给移 动站。 移动站获取到邻区消息后， 对相邻控制站发起扫描和测量， 并切换到 合适的相邻控制站。
实施例二
现有技术中， 移动站无法指定请求的相邻控制站的类型。 对实施一中的 请求类型进一步推广， 不限于仅支持第二通信协议的传统控制站， 以及支持 第一通信协议和第二通信协议的高级控制站， 如图 3所示， 可包括如下步骤： 步骤 301 , 移动站向控制站发送携带请求类型字段的包含部区请求信息 的消息， 请求所述控制站发送相邻控制站的信息；
步骤 302 , 所述控制站接收到所述包含部区请求信息的消息后， 将邻区 信息发送给所述移动站， 所述邻区信息包含移动站请求类型的相邻控制站的 信息。
优选地，所述移动站通过携带请求类型字段的包含部区请求信息的消息， 请求仅支持第二通信协议的传统控制站和 /或同时支持第一通信协议和第二 通信协议的高级控制站和 /或专有仔基站和 /或开放仔基站和 /或所有宏基站的 信息。
也就是说， 请求类型可以是传统控制站、 高级控制站、 专有仔基站、 开 放仔基站、 所有宏基站等各种类型。
相应地， 本发明实施例的无线通信系统， 包括移动站和控制站， 所述移动站用于向控制站发送携带请求类型字段的包含部区请求信息的 消息， 请求所述控制站发送相邻控制站的信息；
所述控制站用于接收到所述包含部区请求信息的消息后， 将邻区信息发 送给所述移动站， 所述邻区信息包含移动站请求类型的相邻控制站的信息。
在 WiMAX系统中， 仔基站作为无线通信系统的补充可针对用户的不同 需求和不同使用环境， 在某些环境或者场景下为用户提供更高质量的无线通 信服务而部署的。 用户入网类型的不同提供了不同的仔基站划分策略， 通常 分为开放的仔基站和专有的仔基站两种。 在不超过最大用户数的前提下， 开 放（OSG ) 的仔基站允许任何用户接入。 专有 （CSG ) 的仔基站又包括完全 专有的仔基站和半专有的仔基站。 完全专有的仔基站只对专有的用户开放， 而半专有的仔基站在能保证专有用户服务质量的前提下允许接入其他非专有 用户。 在当前系统中， 控制站发送的邻区消息中不包含专有仔基站信息， 而 当移动站移动到专有仔基站的覆盖区域时， 就需要获取专有仔基站信息以方 便执行扫描和切换操作。
下面以具体应用实例进一步描述： 应用实例 5
在同时部署有仔基站的系统中， 当移动站逐渐移动到专有仔基站覆盖区 域时， 移动站检测到当前服务基站的通信质量越来越差需要切换到相邻的基 站。 此时相邻的宏基站和开放的基站都暂时处于不可接入状态且移动站可访 问某些专有仔基站。 为了实现切换， 移动站发送包含部区请求信息的消息给 服务基站， 并设置基站请求类型为专有仔基站。 服务基站收到该包含部区请 求信息的消息后， 将相邻专有仔基站的信息通过邻区消息或其他消息单播发 送给移动站。 移动站获取到包含相邻专有仔基站的邻区消息后， 对相邻专有 仔基站发起扫描和测量， 并切换到合适的相邻专有仔基站。
应用实例 6
在同时部署有仔基站的系统中， 当移动站逐渐移动到专有仔基站覆盖区 域时， 由于移动站倾向于选择专有仔基站， 为了实现切换， 移动站发送包含 邻区请求信息的消息给服务基站， 并设置基站请求类型为专有仔基站。 服务 基站收到该包含邻区请求信息的消息后， 将相邻专有仔基站的信息通过邻区 消息或其他消息单播发送给移动站。 移动站获取到包含相邻专有仔基站的邻 区消息后， 对相邻专有仔基站发起扫描和测量， 并切换到合适的相邻专有仔 基站。
实施例三
在 WiMAX通信网络中， 随着标准的发展和基站的升级， 系统中会同时 存在釆用不同标准的基站。 在实际系统中传统控制站的部署大都比较固定， 数目也相对较少。 由此本实施例提出了由高级控制站周期性的或不定期的发 送相邻的控制站信息的方法， 通过该方法， 移动站可以根据需要获取传统控 制站的邻区信息，从而改善无线通信系统移动站切换的性能及降低系统开销。
