技术领域
本发明实施例涉及通信技术领域,尤其涉及一种切换处理方法和系统、 中继装置以及基站。
背景技术 随着移动通信技术的不断发展, 中继技术已经被应用在高速移动的公 共交通工具, 例如快速列车上, 以方便为处于这些高速移动的公共交通工 具上的用户设备 (User Equipment, 以下简称: UE) 提供高质量的通信服 务。
所谓中继技术是在基站和 UE之间增加一个或多个中继器,负责将基站 发送的无线信号做一次或多次信号转发, 直到达到 UE。 以较简单的两跳中 继为例, 中继装置将一条基站到 UE的无线链路分割为基站到中继装置和中 继装置到 UE的两条无线链路, 从而将一条质量较差的链路替换为两条质量 较好的链路, 以获得更高的链路容量以及更好的网络覆盖。 以高速移动的 公共交通工具是列车为例, UE可以接入安装在列车上的中继装置。 随着列 车的高速行驶, 中继装置可以从多个小区穿过。 由于在穿越多个小区时, 控制基站 (Donor E-UTRAN Node B, 以下简称: DeNB ) 会发生改变, 从而 使得 Relay会发生切换, 而且列车上的所有 UE会被执行群组切换。

中继装置在移动过程中, 其路线轨迹以及到达某个特定地点的时间点 等参数信息比较固定, 因此, 中继装置的路线轨迹、 到达某个特定地点的 时间点或者该中继装置发生切换的历史经验信息等作为获取预配置参数的 触发条件, 从而保证该中继装置在从源 DeNB切换到目标 DeNB之前, 即可 完成切换预配置操作。 例如, 当中继装置移动到当前位置与目标 DeNB之间 的距离小于预设距离时, 即可触发中继装置开始获取预配置参数; 当中继 装置在移动过程中, 当前时间达到预设的时间点时, 也可以触发中继装置 开始获取预配置参数; 当中继装置到达一个预设的位置点时, 触发中继装 置开始获取预配置参数。
本实施例以应用在列车上的中继装置为例进行说明。
在现有技术中, 随着列车的高速行驶从多个小区穿过时, 列车里的中 继装置由于 DeNB的改变, 会发生切换, 而且列车上的 UE会被执行群组切 换, 因此, 在短时间内就会有大量的空口信令进行移动中继, 而且还伴随 着中继装置控制的大量 UE的切换资源重配。 源 DeNB在短时间内来不及处 理这些大量的空口信令, 因此, 来不及处理的那些空口信令对应的 UE还没 有来得及执行向目标 DeNB的切换就已经离开了源 DeNB, 此时 UE由于没有 接入任何小区而出现服务中断的情况; 即使 UE来得及完成切换流程, 也会 因为接入链路和中继链路两段链路的接续重配, 导致业务中断时间过长, 影响业务的连续性。
在本实施例中, 由于列车上的中继装置, 其移动的路线轨迹以及到达 某个特定地点的时间点比较固定, 因此, 本实施例中, 中继装置在源控制 基站作出切换判决之前, 可以对中继装置从源 DeNB切换到目标 DeNB所需 的资源预先进行配置, 从而使得中继装置在需要执行从源 DeNB切换到目标 DeNB的操作之前, 即可做好切换准备, 在切换时即可根据该预先配置的资 源从源 DeNB切换到目标 DeNB,而不用在已经开始从源 DeNB切换到目标 DeNB 时, 才进行资源配置。 因此, 本实施例的切换处理方法缩短了中继装置在 切换过程中的切换时延, 缩短了中继装置控制的 UE发生服务中断的时间, 保障了中继装置控制的 UE在切换过程中的服务连续性, 提高了业务服务质 在本发明切换处理方法再一个实施例中, 步骤 101之后, 还可以包括: 根据所述预配置参数向用户设备发送预配置信息, 以使所述用户设备 根据所述预配置信息进行参数配置处理。
中继装置在获取预配置参数后,可以向该中继装置控制的 UE发送该 UE 进行参数配置处理所需的预配置信息, 预配置信息可以是预配置参数的全 部或者一部分, 从而使得 UE在进行参数重配操作之前, 即可做好参数配置 处理的准备, 在中继装置的控制下根据该预配置信息进行参数配置处理, 而不用在中继装置已经开始从源 DeNB切换到目标 DeNB时, 才进行资源的 重新配置。 在本发明切换处理方法还一个实施例中, 预配置参数, 可以包括: 目 标小区频率信息、 目标小区的带宽信息、 跟踪区标识 (Trace Area Identifier , 以下简称: TAI )、 目标小区广播单频网子帧配置信息 (Multicast Broadcast Single Frequency Network, 以下简禾尔: MBSFN) 、 目标小区的 PCI信息以及公众陆地移动网络(Public Land Mobile Network, 以下简称: PLMN)标识信息中的至少一种参数信息。 辅助信息, 可以包括: 当前位置信息、 当前速度信息、 当前时间点信息、 当前频率信息、 物理小 区标识 (Physical Cell Identity, 以下简称: PCI ) 信息以及历史记录信 息中的至少一种参数信息。
需要说明的是, 上述预配置参数以及辅助信息并不限于上述列举出的 诸多参数, 本领域技术人员可以理解的是, 上述预配置参数以及辅助信息 可以根据需要进行选择。
举例来说,中继装置可以在与目标 DeNB之间的距离小于预设的距离时, 上报中继装置的当前位置信息、 当前速度信息、 当前时间点信息、 当前频 率信息、 PCI信息以及历史记录信息中的至少一种参数信息,然后根据这些 辅助信息即可获取相应的预配置参数, 该预配置参数即可包括目标小区频 率信息、 目标小区的带宽信息、 TAI、 目标小区 MBSFN、 目标小区的 PCI信 息以及 PLMN标识信息中的至少一种参数信息, 从而使得中继装置可以根据 目标小区频率信息、 目标小区的带宽信息、 TAI、 目标小区 MBSFN、 目标小 区的 PCI 信息以及 PLMN标识信息进行切换预配置处理, 以便于后续从源 DeNB切换到目标 DeNB。
上述实施例在实现过程中, 可以根据 DeNB的网络的实际规划和部署情 况, 预先为中继装置生成对应的配置参数集, 这些配置参数集可以保存在 中继装置的操作维护 (Operation and Maintenance, 以下简称: 0&M) 系 统中、 源 DeNB的 0&M系统中、 目标 DeNB的 0&M系统中或者移动性管理实 体中。 而且这些配置参数集中的预配置参数, 也可以在当前的网络配置发 生改变时被更新。

步骤 703、 中继装置向源 DeNB发送测量报告;
中继装置在不断移动的过程中, 由于信号变化, 需要发起从源 DeNB到 目标 DeNB的切换, 因此, 中继装置需要向源 DeNB发送测量报告。
步骤 704、 源 DeNB决定切换后, 向目标 DeNB发送切换请求消息; 步骤 705、 目标 DeNB向源 DeNB发送切换请求确认消息;
由于在步骤 702中, 目标 DeNB已经为该中继装置配置好资源信息, 因 此, 在步骤 705中, 目标 DeNB不需要再进行资源重配, 而是可以在接收到 源 DeNB发送的切换请求消息后直接向源 DeNB反馈切换请求确认消息, 在 该切换请求确认消息中可以携带在切换前就已经预配置好的中继装置的资 源信息;
步骤 706、 源 DeNB收到切换请求确认消息后, 向中继装置发送切换命 令消息;
步骤 707、 中继装置收到切换命令消息后, 向其控制的 UE发送切换命 令消息;
步骤 708、 源 DeNB释放资源, 切换流程结束。
本实施例中, 源 DeNB可以在中继装置发起切换前, 根据中继装置移动 的位置信息或者时间信息等向目标 DeNB发送该中继装置的上行物理信息, 从而使得目标 DeNB在中继装置发起切换之前即可为该中继装置配置资源信 息, 因此, 目标 DeNB不必在后续中继装置发起从源 DeNB切换到目标 DeNB 时再为中继装置重配资源信息, 而是可以快速地为中继装置提供已经预先 配置好的资源信息, 从而缩短了中继装置在切换过程中的切换时延, 进一 步保障了中继装置控制的 UE在切换过程中的服务连续性, 提高了业务服务 质量。 图 8为本发明中继装置一个实施例的结构示意图, 如图 8所示, 本实 施例的中继装置可以包括: 第一发送模块 11、第一接收模块 12以及切换模 块 13。其中, 第一发送模块 11用于在源控制基站做出切换判决之前, 发送 用于获取预配置参数的辅助信息; 第一接收模块 12用于接收所述预配置参 数; 切换模块 13用于根据所述预配置参数, 从所述源控制基站切换到所述 目标控制基站。

上述系统实施例中, 中继装置可以在源控制基站作出切换判决之前, 对中继装置从源 DeNB切换到目标 DeNB所需的资源预先进行配置, 从而使 得中继装置在需要执行从源 DeNB切换到目标 DeNB的操作之前, 即可做好 切换准备,在切换时即可根据该预先配置的资源从源 DeNB切换到目标 DeNB, 而不用在已经开始从源 DeNB切换到目标 DeNB时, 才进行资源配置; 而且, 中继装置也可以在源控制基站作出切换判决之前, 向 UE发送预配置信息, 从而使得 UE在中继装置切换之前即可进行参数的重新配置, 从而也避免了 UE在中继装置的切换过程中出现服务中断的现象。 因此, 本实施例的切换 处理方法缩短了中继装置在切换过程中的切换时延, 以及中继装置控制的 UE发生服务中断的时间,保障了中继装置控制的 UE在切换过程中的服务连 续性, 提高了业务服务质量。而且, 在中继装置从源 DeNB切换到目标 DeNB 之前, 源 DeNB和目标 DeNB也可获知该预配置参数, 从而使得源 DeNB和目 标 DeNB在中继装置的切换过程中不需要再进行资源配置, 进 ·步保证了服 务的连续性, 以提高业务服务质量。
