本发明所述的终端包括多个天线， 所述第一天线集包括至少一个天线 , 所述第二天线集包括至少一个天线， 并且， 所述第一天线集的天线与所述 第二天线集的天线不同。 当所述第二天线集包括至少两个天线时， 所述第
二天线集可以釆用多天线的接收分集方式， 本发明不限于此。
本发明所述的终端为多天线终端， 并且为多模终端， 支持第一基站的 通讯模式和第二基站的通讯模式。 本发明中多天线终端的无线通讯模式包 括但是不限于 GSM ( Global System for Mobile Communications, 全球移动 通信系统）、 CDMA2000 ( Code Division Multiple Access, 码分多址移动通 信）、 WCDMA ( Wideband CDMA,宽频 CDMA )、 HSPA( High Speed Packet Access, 高速分组接入）、 CDMA 2000 lxEV-DO ( CDMA2000 lx演进（第 三代移动通信技术的一条路径的一个阶段））、 TD-SCDMA ( Time Division-Synchronous CDMA,时分同步 CDMA )、 LTE( Long Term Evolution, 长期演进)、 Wi-MAX ( World Interoperability for Microwave Access, 全球微 波接入互操作性）。 本发明所述的模间切换可以为上述的任意两种无线通讯 模式之间的切换， 并且不限于此。
上述方案中， 在收到切换指令之后进行切换之前， 多天线终端对所述 多天线终端的第二天线集和所述多天线终端的第二基带处理单元进行适合 第二基站通讯模式的配置， 完成所述多天线终端与所述第二基站之间进行 通信的准备； 在所述预定切换时间， 所述多天线终端利用所述第二天线集 和所述第二基带处理单元， 与所述第二基站开始通信。 因此， 能够缩短现 有技术在模间硬切换时的通讯中断时间。
如图 2所示， 为本发明所述的一种终端进行模间切换的方法， 包括： 步骤 201 ,所述终端利用所述终端的第一天线集和第二天线集和第一基 带处理单元， 与所述第一基站进行通信。
步骤 202, 终端从第一基站接收切换指令， 所述切换指令是将所述终端 在预定切换时间从所述第一基站切换到第二基站的指令， 所述第二基站的 通讯模式和所述第一基站的通讯模式不同。
步骤 203 , 在接收所述切换指令之后、 所述预定切换时间之前， 所述终
端利用其第一天线集和第一基带处理单元， 保持与所述第一基站的通信，。 步骤 204, 在接收所述切换指令之后、 所述预定切换时间之前， 所述终 端释放所述第二天线集。
步骤 205 , 在释放所述第二天线集后， 所述终端对其第二天线集和第二 基带处理单元进行适合第二基站通讯模式的配置， 该步骤 205 可以包括： 所述终端启动所述终端的第二基带处理单元； 所述终端将所述第二天线集 切换到所述第二基站的模式和频段； 所述终端构建从所述第二天线集到所 述第二基站的射频通道； 所述终端利用所述第二天线集对所述第二基站进 行捕获； 所述终端利用所述射频通道与所述第二基站进行同步。 其中， 步 骤 203与步骤 204和步骤 205之间为并行处理。
步骤 206, 所述终端在所述预定切换时间， 切换到配置好的所述第二天 线集和所述第二基带处理单元以与所述第二基站通信， 并停止所述第一天 线集和所述第一基带处理单元与所述第一基站的通信。
步骤 207, 所述终端判断切换是否成功； 所述终端判断切换是否成功的 步骤具体为： 所述终端判断所述终端是否接收到所述第二基站的信号。 本 领域技术人员明白， 还可以用其他方法判断切换是否成功。
步骤 208, 如果切换成功， 则释放所述第一天线集和所述第一基带处理 单元。
从上述实施例可以看出， 如果在初始状态， 所述终端利用所述终端的 第一天线集和第二天线集和第一基带处理单元， 与所述第一基站进行通信； 则终端在接收到切换指令后， 需要先释放第二天线集， 以使后续流程中， 第二天线集与第二基站进行通信。
如果在初始状态， 所述终端利用其第一天线集和第一基带处理单元， 与所述第一基站进行通信； 则终端在接收到切换指令后， 不需要先释放第 二天线集。
本发明中， 所述第一天线集包括至少一个天线， 所述第二天线集包括 至少一个天线， 当所述第二天线集包括至少两个天线时， 所述第二天线集 可以釆用多天线的接收分集方式与所述第二基站通信， 本发明不限于此。 所述第二天线集的天线与所述第一天线集的天线不同； 第一基带处理单元 与第二基带处理单元单元不同， 从所述第一天线集到所述第一基站的射频 通道与从所述第二天线集到所述第二基站的射频通道不同。 从所述第二天 线集到所述第二基站的射频通道与从所述第一天线集到所述第一基站的射 频通道之间相互独立。
本发明中多天线终端的无线通讯模式包括但是不限于 G S M、 CDMA2000, WCDMA、 HSPA、 CDMA 2000 lxEV-DO、 TD-SCDMA、 LTE、 Wi-MAX。本发明所述的模间切换可以为上述的任意两种无线通讯模式之间 的切换， 并且不限于此。
上述方案中， 多天线终端包括多个天线， 并且支持多个无线模式。 终 端拥有可以并行处理的多模基带处理资源， 可以同时进行一个模式的接收 和另一个模式的接收准备工作， 包括测量、 跟踪、 信道估计等。 如果多模 实现是不同模式的 ASIC ( Application Specific Integrated Circuits, 专用集成 电路）实现叠加， UE ( User Equipment , 用户终端）可以利用这些资源并行 工作； 如果多模实现是以共享资源平台软配置（SDR ) 的方式， UE可以釆 用部分配置的形式， 可以只配置需要支持硬切换准备工作的最小资源来完 成两个模式的并行工作。
本发明方案中的切换准备工作， 不仅可以减少传统硬切换方案中不可 避免的通讯中断时间， 而且由于提前对于第二基站的服务小区进行跟踪和 信道估计等， 对于可能需要一定时间才能稳定的第二基站的服务小区无线 接收有很大的帮助， 能够使得模间的切换更加稳定。 本发明所述的方案充 分利用多天线终端的资源， 使得硬切换到第二基站的服务小区的准备更加
充分。 不仅能够减少现有技术中针对单天线硬切换方案的通讯中断时间， 而且能够增加切换后新连接的接收稳定性， 可以使得多模间的硬切换更加 稳定， 具有类似于软切换的用户体验效果。
以下以双天线终端进行从 LTE到 WCDMA的硬切换的应用场景为例， 描述本发明所述的双天线终端进行模间硬切换的方法。
所述的双天线终端有两根对等的天线 A、 B ,可以接收 LTE的射频信号， 也可以接收 WCDMA 的射频信号， 并且拥有可以同时并行处理 LTE 和 WCDMA两种制式基带信号的基带处理资源。
如图 3所示， 所述方法包括：
步骤 301 , 在初始状态， 双天线终端通过天线 A, 或者同时利用天线 A 和天线 B以接收分集（ RxD ) 的方式与 LTE基站 S进行通讯。 LTE基站 S 发出指令让 UE在未来某一时刻切换到 WCDMA基站 D。 该步骤中， 模间 硬切换发起由系统基站控制 ,提前通知 UE准备从原无线制式基站切换到新 的无线制式目标基站。
步骤 302, UE收到指令后， 在切换时刻之前提前一定时间开始执行切 换准备。提前时间与 UE本身建立与 WCDMA通讯的准备时间有关， 由 UE 自行决定。 UE将釆用单天线接收的方式用天线 A维持和基站 S的通讯。开 启 WCDMA的基带处理资源， 并将天线 B调整到接受目标基站 D的信号， 并将接收到的信号由 WCDMA基带处理资源处理， 完成正式接收前的搜索 同步等工作。 该步骤中， 双天线终端接到模间硬切换的指令后， 双天线终 端在与系统约定的模间硬切换时间前， 开始准备工作。 一方面， 利用双天 线终端的一个天线维持与原基站的通讯。 另一方面， 开启双天线终端的目 标基站的无线制式基带接收资源， 并利用空闲下来的天线 B切换到目标基 站的模式和频段； 构成一条与原基站接收完全独立、 可以并行的从射频天 线到基带接收处理资源的射频通道， 对目标基站的服务小区进行捕获和同
步， 做好接收信号的配置等准备工作。
步骤 303 , 在约定的切换时间， UE利用做好准备工作的接收天线 B和 基带处理资源开始与目标基站 D通信。 该步骤中， 在与系统约定的切换时 间， 双天线终端停止通过天线 A与原基站通信， 利用已经建立的天线 B到 新制式基带处理资源完成对目标基站信号的接收； 完成硬切换。
步骤 304,双天线终端在确认切换顺利完成以后，释放天线 A和原 LTE 的基带处理资源。
当需要模间切换时， 原基站的服务小区的信号应该已经很弱了， 因此 不会处于 MIMO ( multiple input multiple output, 一种使用超过一个天线来 传输和接收同一频道内的两个或多个独立数据流的无线技术）状态， 因此 用所有多天线保持通讯的必要性在绝大多数场景下不存在。 如果终端处于 接收分集状态下， 提前减少接收分集所用天线的数目， 通讯质量会有短时 间的下降， 但是能够减少现有技术中模间切换时短的通讯中断时间。
