切换方法和移动站
技术领域 本发明涉及通信领域， 并且特别地， 涉及一种切换方法和移动站。 背景技术 目前， 无线通信系统使用电磁波和固定的或者移动的无线通信终端（例 如， 移动无线电话或附有无线通信卡的笔记本电脑等设备均可被称为终端） 进行通信。一般地， 在进行无线通信时， 终端位于系统的无线覆盖范围之内， 并通过无线通信信道与系统进行通信。 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， 从理论上来说， 基站应该位 于小区的中央。 为了扩展覆盖或者扩展容量， 一个或多个中继站可以放置在 终端和基站之间。 对于移动站来说， 中继站尤相当于一个基站。 终端从一个 小区移动到另一个小区时， 为了保持通信， 就需要进行切换。 在相关技术中， 切换技术可以分为硬切换和软切换两种。 其中， 硬切换 的特点是先中断与原服务站的连接， 再建立与目标站的业务连接， 硬切换的 过程可分为几个子过程： 1、 网络拓朴获取 （小区重选）， 2、 切换准备和初 始化， 3、 目标站下行同步， 4、 中止原服务站连接， 进入新小区。 由于通信技术的快速发展， 出现了不同类型的通信系统， 这些通信系统 能够兼容传统的终端， 同样地， 当前的终端也应该能够接入传统站 （支持旧 通信协议的基站或中继站）。 目前， 在考虑兼容性的技术中， 把当前站（支持 新通信协议的基站或中继站） 的帧结构区域分成了当前区域和传统区域。 当 前终端可以工作在当前区域或传统区域， 而传统终端只能工作在传统区域。 对于传统终端， 当前站的传统区域就是一个传统站。 此外， 当前终端接入传 统站工作时， 从传统站的角度看， 这个终端就是一个传统终端。 目前， 在相关技术中， 当前终端从传统站切换到当前站时可以分为两个 步骤， 第一步是当前终端从传统站切换到当前站的传统区域， 第二步是当前 终端从当前站的传统区域切换到当前区域。 上述处理过程可以使得传统站的 空口协议不改变， 但是， 却增加了切换的延时。 因此， 需要新的方法解决这 个问题。 发明内容 考虑到目前移动站从服务站切换到目标站的目标区域时，切换时延过长 的问题而故出本发明， 为此， 本发明的主要目的在于提供一种切换方法和移 动站， 以解决相关技术中存在的上述问题。 才艮据本发明的一个方面， 提供了一种切换方法， 用于移动站从服务站切 换到目标站的目标区域。 才艮据本发明的切换方法包括： 移动站从服务站切换到目标站的传统区 域， 并在传统区域上发送第一测距请求消息； 移动站接收第一测距请求响应 消息， 并获取第一测距请求响应消息中携带的目标区域相关信息； 移动站根 据相关信息切换到目标区域。 此外， 上述移动站在传统区域上发送第一测距请求消息之前， 上述方法 进一步包括： 在移动站与传统区域进行同步后， 获取上行参数， 并发送第一 初始测距码， 其中， 在第一初始测距码为随机测距码的情况下， 釆用随机接 入方式发送随机测距码； 移动站接收初始测距反馈信息。 此外， 上述移动站在传统区域上发送第一测距请求消息之前， 上述方法 进一步包括： 在移动站与传统区域进行同步后， 移动站在预先分配的测 巨资 源上发送第一初始测距码， 其中，在第一初始测距码为指定测距码的情况下， 釆用随机接入方式发送随机测距码； 在第一初始测距码为随机测距码的情况 下， 釆用在指定时隙上发送的方式发送随机测距码； 在第一初始测距码为指 定测距码的情况下， 釆用在指定时隙上发送的方式发送指定测距码； 移动站 接收初始测距反馈信息。 其中， 上述移动站在传统区域上发送第一测 巨请求消息的处理具体为： 移动站在传统区域预先分配的资源上发送第一测 巨请求消息； 或者移动站才艮 据初始测距反馈信息发送第一测距请求消息。 其中， 上述目标区域相关信息包括以下至少之 目标区域的测距资源 息、 目标区域的连接信息、 目标区域的参数信息。 其中，上述目标区域的测距资源信息为竟争性测距资源或非竟争性测距 资源。 其中， 目标区域的测距资源信息包括以下至少之一： 时间参数、 频率参 数、 子信道参数、 基站标识、 前导参数、 目标区域的切换标识、 测距码参数。 其中， 目标区域的连接信息包括以下至少之一： 移动站在目标区域中的 标识、 移动站在目标区域中的连接标识、 连接标识数据、 预先分配的基本连 接标识。 其中， 目标区域的参数信息包括以下至少之一： 切换模式、 切换操作模 式、 资源保持标志、 切换指示分配标识、 切换优化指引信息、 网络辅助切换 支持信息、 服务水平预测信息。 此外， 上述移动站根据相关信息切换到目标区域之后， 进一步包括： 移 动站向目标区域发送第二测距请求消息。 此外， 移动站向目标区域发送第二测距请求消息之前， 上述方法进一步 包括： 在移动站与目标区域进行同步后， 移动站在关联操作中预先分配的测 距资源上发送第二初始测距码， 其中， 在第二初始测距码为随机测距码的情 况下， 釆用随机接入方式发送随机测距码； 在第二初始测距码为指定测距码 的情况下， 釆用随机接入方式发送指定测距码； 在第二初始测距码为随机测 距码的情况下， 釆用在指定时隙上发送的方式发送随机测距码； 在第二初始 测距码为指定测距码的情况下， 釆用在指定时隙上发送的方式发送指定测距 码； 移动站接收初始测距反馈信息。 其中， 移动站向目标区域发送第二测距请求消息的处理具体为： 移动站 在目标区域预先分配的资源上发送第二测距请求消息； 或者移动站才艮据调整 后的初始测距反馈信息发送第二测距请求消息。 此外， 移动站向目标区域发送第二测距请求消息之后， 进一步包括： 移 动站接收测距响应消息， 并获取测距响应消息中的测距资源信息、调整参数、 初始测: ί巨成功指示中的至少之一。 其中， 移动站为支持旧通信协议和新通信协议的移动站， 服务站为支持 旧通信协议的基站或中继站， 目标站为支持旧通信协议和新通信协议的基站 或中继站， 其中， 目标站的传统区域使用旧通信协议为支持旧通信协议的移 动站提供月艮务， 目标站的目标区域支持新通信协议。 才艮据本发明的另一方面， 提供了一种移动站， 用于从服务站切换到目标 站的目标区 i或。 才艮据本发明的移动站包括： 第一切换模块， 用于使移动站从服务站切换 到目标站的传统区域； 发送模块，用于在传统区域上发送第一测距请求消息； 接收模块， 用于接收第一测距请求响应消息， 并获取第一测距请求响应消息 中携带的目标区域相关信息； 第二切换模块， 用于根据相关信息使移动站切 换到目标区域。 借助于本发明的技术方案，移动站在目标站的传统区域上获取测距请求 响应消息中目标区域相关信息， 并根据获取的相关信息切换到目标区域， 减 少了两次切换中不必要的流程， 能够提高兼容通信系统切换的效率。 本发明的其它特征和优点将在随后的说明书中阐述， 并且， 部分地从说 明书中变得显而易见， 或者通过实施本发明而了解。 本发明的目的和其他优 点可通过在所写的说明书、 权利要求书、 以及附图中所特别指出的结构来实 现和获得。 附图说明 附图用来提供对本发明的进一步理解， 并且构成说明书的一部分， 与本 发明的实施例一起用于解释本发明， 并不构成对本发明的限制。 在附图中： 图 1是才艮据本发明实施例的切换方法的流程图； 图 2是才艮据本发明实施例的实例 1的流程图； 图 3是根据本发明实施例的实例 1的详细处理的信令流程图； 图 4是才艮据本发明实施例的实例 2的流程图； 图 5是根据本发明实施例的实例 2的详细处理的信令流程图； 图 6是才艮据本发明实施例的移动站的框图。 具体实施方式 功能相无述 目前， 在相关技术中， 当前终端从传统站切换到当前站时， 存在较长的 切换延时， 在当前终端切换到传统区域时， 由于不需要在传统区域中传输数 据， 因而可以不要全部完成传统区域中的切换过程， 而是尽快的接入到当前 区域中去， 以缩短切换的延时。 因此， 本发明提出了一种解决方案， 包括： 移动站从月艮务站切换到目标站的传统区域后， 在目标站的传统区域上发送测 距请求消息， 移动站在接收到测距请求响应消息后， 获取测距请求响应消息 中目标区域相关信息， 并根据获取的相关信息切换到目标区域。 需要说明的是， 上述移动站为支持旧通信1"办议和新通信1"办议的移动站， 服务站为支持旧通信协议的基站或中继站， 目标站为支持旧通信协议和新通 信协议的基站或中继站， 其中， 目标站的传统区域使用旧通信协议为支持旧 通信协议的移动站提供月艮务， 目标站的目标区域支持新通信协议。 以下结合附图对本发明的优选实施例进行说明， 应当理解， 此处所描述 的优选实施例仅用于说明和解释本发明， 并不用于限定本发明。 方法实施例 才艮据本发明的实施例， 提供了一种切换方法， 用于移动站从服务站切换 到目标站的目标区域， 图 1是才艮据本发明实施例的切换方法的流程图， 如图 1所示， 包括以下处理： 步骤 S102, 移动站从月艮务站切换到目标站的传统区域， 并在传统区域 上发送测 3巨请求消息； 在发送测 3巨请求消息时， 移动站可以在传统区域预先 分配的资源上发送测距请求消息， 也根据初始测距反馈信息发送测距请求消 息。 需要说明的是， 在步骤 S102之前， 移动站首先需要进行初始测距， 其 中， 初始测: ί巨分为两种方式， 下面， 对这两种情况进行详细的说明。 方式一 第一步， 在移动站与传统区域进行同步后， 获取上行参数， 并发送初始 测距码， 并且， 在初始测距码为随机测距码的情况下， 釆用随机接入方式发 送随机测: ί巨码; 第二步， 移动站接收初始测距反馈信息， 其中初始测距反馈信息中至少 包括： 使用接收到的测距码作为反馈给移动站的标识、 使用参数的相对值或 者绝对值作为调整的指示。 方式二 第一步， 在移动站与传统区域进行同步后， 移动站在预先分配的测 巨资 源上发送初始测距码， 其中， 在初始测距码为指定测距码的情况下， 釆用随 机接入方式发送随机测: ί巨码； 在初始测: ί巨码为随机测: ί巨码的情况下， 釆用在 指定时隙上发送的方式发送随机测距码； 在初始测距码为指定测距码的情况 下， 釆用在指定时隙上发送的方式发送指定测距码； 第二步， 移动站接收初始测距反馈信息， 其中初始测距反馈信息中至少 包括： 使用接收到的测距码作为反馈给移动站的标识、 使用参数的相对值或 者绝对值作为调整的指示。 从上述的两种方式可以看出，移动站可以在获得上行参数后发送初始测 距码，也可以在关联操作分配的测距资源上发送初始测距码。 需要说明的是， 在移动站发起移动站扫描请求后， 移动站接收的移动站扫描响应消息中包含 有扫面期间对目标区 i或测; ί巨与否以及测; ί巨响应方式的指示， 这种测; ί巨在 16e 标准中被成为关联操作。 步骤 S 104 , 移动站接收测距请求响应消息， 并获取测距请求响应消息 中目标区域相关信息， 其中， 目标区域相关信息具体包括： 目标区域的测距 资源信息、 目标区域的连接信息、 目标区域的参数信息； 下面， 对上述信息 进行详细的说明。
