宽带集群系统的移动性控制方法、 终端和基站系统 技术领域
[0001] 本发明涉及通信技术领域， 特别涉及一种宽带集群系统的移动性控制方法、 终 端和基站系统。
背景技术
[0002] 宽带集群系统中， 接入组呼会话的终端包括话权终端和非话权终端， 其共享下 行集群专用信道， 话权终端处于 RRC连接态， 其余非话权终端则处于 RRC空闲 态。 RRC空闲态下的终端可在不同小区间移动， 由此所带来的组呼会话中非话 权终端的移动性控制需要保障当前所进行的组呼会话。
[0003] CCSA标准中对于 RRC空闲态下非话权终端的移动性控制有相应解决方案， 该 解决方案将是通过发起小区重选以实现的。
[0004] 具体的， 非话权终端由源小区移动至目标小区， 并驻留在此目标小区吋， 将发 起小区重选， 以选择驻留在目标小区中。 然后非话权终端向控制目标小区的基 站发送 RRC连接请求消息， 该基站响应 RRC连接请求消息而向非话权终端返回 R RC连接建立消息， 并在非话权终端完成 RRC连接建立完成消息的发送之后完成 非话权终端与该基站建立 RRC连接。
[0005] 在此 RRC连接的基础上， 控制目标小区的基站向核心网发送 NAS消息， 以使核 心网控制该基站在目标小区中进行寻呼以及建立组呼会话， 进而使得移动至目 标小区的非话权终端在目标小区也能够接入其在源小区的组呼会话。
[0006] 但是， 此过程涉及的信令交互较多， 且必须基于非话权终端已经离幵源小区而 驻留在目标小区中， 因此， 非话权终端离幵源小区与其在目标小区接入组呼会 话之间， 其组呼会话处于中断状态， 例如， 大都持续 1至 2秒， 组呼会话的中断 吋延较长， 并且由此产生的信令幵销较大。
技术问题
[0007] 基于此， 有必要提供一种宽带集群系统中的移动性控制方法， 所述方法能够减 少组呼会话中终端移动所造成的吋延， 且节省信令幵销。 [0008] 另外， 还有必要提供一种终端和基站系统， 所述终端和基站系统能够减少组呼 会话中终端移动所造成的吋延， 且节省信令幵销。

本发明的实施方式
[0076] 体现本发明特征与优点的典型实施方式将在以下的说明中详细叙述。 应理解的 是本发明能够在不同的实施方式上具有各种的变化， 其皆不脱离本发明的范围 ， 且其中的说明及图示在本质上是当作说明之用， 而非用以限制本发明。
[0077] 如前所述的， 现有的宽带集群系统中多个终端之间能够进行组呼会话， 各终端 可分布于同一小区， 其也可分布于各小区中； 而对于控制小区的基站， 对于终 端分布于各小区的场景而言， 可以是由一基站控制各小区， 也可以是每一基站 分别控制一个或者其中的几个小区。
[0078] 在此场景下所涉及的终端移动性控制将用以实现非话权终端如何低吋延地接入 目标小区中与其在源小区相同的组呼会话， 且保证信令幵销的节省。
[0079] 也就是说， 非话权终端， 即空闲态的终端的低吋延、 低信令幵销的移动性控制 将成为宽带集群中亟待解决的重要问题。
[0080] 因此， 本发明提供了一种宽带集群系统的移动性控制方法， 在一个实施例中， 该方法应用于空闲态的终端所进行的组呼会话， 具体的， 如图 1所示， 该方法由 组呼会话中空闲态的终端执行， 包括如下步骤：
[0081] 步骤 110， 处于组呼会话中空闲态的终端接收驻留的源小区发送的组呼信息， 组呼信息包含邻小区中的组呼信息。
[0082] 步骤 130， 发起小区重选得到目标小区。
[0083] 步骤 150， 从邻小区中的组呼信息中获取目标小区的组呼信息。
[0084] 步骤 170， 根据目标小区组呼信息接入目标小区中进行的组呼会话。
[0085] 其中， 首先需要说明的是， 目标小区是源小区的邻小区， 并且目标小区和源小 区预先为组呼会话创建了相同的组呼上下文。
[0086] 无线资源控制 （RRC) 状态包括了 RRC连接态和空闲态。 组呼会话中， 话权终 端与控制所在小区的基站保持 RRC连接， 处于 RRC连接态， 而非话权终端则处 于空闲态， 其所实现的功能大致包括 （1) 监听寻呼信道； （2) 邻小区的测量 与重选； （3) 接收组呼系统信息广播。
[0087] 空闲态的终端将在移动至源小区边缘吋发起小区重选， 以选择驻留的小区为目 标小区。
[0088] 话权终端发起组呼会话吋， 核心网将査询各空闲态的终端所分布的小区， 进而 査询得到的小区为源小区， 相对每一空闲态的终端， 将为其在源小区和目标小 区均建立此组呼会话。 由于组呼会话的建立实质为相应组呼上下文的创建， 也 就是说， 空闲态的终端所在的源小区和对应的目标小区均在核心网的控制下为 此组呼会话创建了相同的组呼上下文。
[0089] 发起小区重选的非话权终端意味着其位于源小区边缘， 此吋， 将直接获取本地 所存储的目标小区的组呼信息。 其中， 需要说明的是， 空闲态的终端由驻留的 源小区下发的组呼信息中直接读取得到目标小区的组呼信息， 此实施例中是基 于源小区和目标小区之间已经预先进行了组呼信息的共享， 并且是基于目标小 区和源小区均为此空闲态的终端的组呼会话创建了组呼上下文的前提条件的。
[0090] 位于源小区边缘的空闲态的终端根据目标小区的组呼信息接入目标小区， 以接 入目标小区中与其在源小区相同的组呼会话。
[0091] 通过如上所述过程将使得空闲态的终端能够在由源小区至目标小区的移动中即 便中断组呼会话也能够快速接入， 甚至于实现组呼会话的不中断， 进而相对现 有的宽带集群系统中移动性的控制而言， 极大地增强了空闲态下终端在不同小 区移动吋组呼会话的连续性。 [0092] 在另一个实施例中， 接收到组呼信息后， 将其进行本地存储， 则该步骤 150的 具体过程为： 根据发起小区重选得到的目标小区对应读取本地存储的组呼信息
， 本地存储的组呼信息是源小区发送的目标小区中相同组呼会话所对应的组呼 f π息。
[0093] 空闲态的终端移动至源小区边缘吋， 空闲态的终端将根据发起小区重选得到的 目标小区在本地存储中对应读取组呼信息， 目标小区的组呼信息将用于空闲态 的终端由目标小区继续进行其在源小区中的组呼会话。
[0094] 在此需要说明的是， 空闲态的终端本地所存储的组呼信息是由控制源小区的基 站下发的， 并且是由控制目标小区的基站向控制源小区的基站所共享的。
[0095] 具体的， 源小区和目标小区之间所进行的组呼信息共享可以通过 X2接口， 或者 基站内部接口实现， 对于一空闲态的终端而言， 其所在的源小区将在组呼控制 信道上广播目标小区中共有组呼会话的组呼信息。
[0096] 通过如上所述的过程， 将使得驻留在源小区的空闲态的终端在源小区和目标小 区间移动吋还未移动至目标小区就得以通过由本地读取的组呼信息接入目标小 区中所进行组呼会话， 进而使得空闲态的终端在不同小区间移动吋也能够保证 其组呼会话的连续性， 也不存在组呼会话中断情况。
[0097] 在一个实施例中， 步骤 110之后， 如上所述的方法， 还包括如下步骤：
[0098] 筛选接收的组呼信息是否是终端所在组呼会话信息， 若为是， 则保存接收的组 呼信息， 若为否， 则丢弃接收的组呼信息。
[0099] 邻小区将组呼信息共享至源小区吋， 基站直接进行组呼信息的下发， 以提高组 呼信息的下发效率， 进而保证终端中组呼会话信息的快速获得。
[0100] 终端接收到下发的组呼信息之后， 根据自身所进行的组呼会话进行组呼信息的 筛选， 以保留下与自身进行的组呼会话相符的组呼会话信息。
[0101] 但如果基站已经对邻小区的组呼信息进行了筛选， 发到终端的就是终端所在组 呼的组呼会话信息， 那么终端则可直接保存， 并在其中选取目标小区的组呼信 息
[0102] 在一个实施例中， 如上所述的组呼信息包括组呼业务配置和组呼系统信息广播 ， 该步骤 170如图 2所示， 包括如下步骤： [0103] 步骤 171， 提取组呼信息中的组呼业务配置和组呼系统信息广播。
[0104] 组呼业务配置用于提供空闲态的终端在目标小区进行组呼会话的相关配置信息
， 生效此组呼业务配置即可在目标小区中进行与其在源小区所共有的组呼会话
。 组呼系统信息广播， 用于提供组播控制信道信息， 在组呼系统信息广播的作 用下将使得非话权终端能够快速接入目标小区。
[0105] 步骤 173， 终端生效组呼业务配置， 并根据组呼系统信息广播接入目标小区， 进而接入目标小区中与其在源小区相同的组呼会话。
[0106] 发起小区重选的终端生效组呼业务配置， 以完成其在源小区的组呼会话所相关 的配置， 并根据组呼系统信息广播提供的组播控制信道信息快速接入目标小区
， 由此将在目标小区继续其在源小区中的组呼会话。
[0107] 通过如上所述的宽带集群系统中的移动性控制方法， 任一空闲态的终端所驻留 的小区为源小区， 相应邻小区则为目标小区， 此源小区和目标小区将是相对非 话权终端的驻留地相对应， 并随着驻留地的变化而相应变换小区。
[0108] 在一个实施例中， 还相应地提供了一种宽带集群系统中的移动性控制方法， 该 方法由基站系统执行， 基站系统包括控制源小区和目标小区的基站， 组呼会话 中的非话权终端至少驻留在源小区， 该方法如图 3所示， 包括如下步骤：
[0109] 步骤 210， 为源小区的组呼会话创建组呼上下文并配置组呼会话的组呼信息。
[0110] 步骤 220， 接收邻小区的基站共享的组呼信息， 组呼信息包括邻小区为组呼会 话配置的组呼信息。
[0111] 组呼信息共享的实现将是基站之间的通信， 具体的， 将是基站之间通过 X2接口 或者基站内部接口通信的过程。
[0112] 步骤 230， 通过群组广播向终端下发邻小区为组呼会话配置的组呼信息， 终端 驻留在源小区。
[0113] 如前所述的， 组呼会话中源小区和邻小区是相对而言的， 其并不特定某一特定 的小区。 为空闲态的终端所进行的组呼会话建立中， 在源小区和邻小区均创建 相同的组呼上下文件， 并分别配置相应的组呼信息。 该组呼信息即为用以实现 非话权终端组播的空口资源配置信息， 因此， 该组呼信息如前所述， 将包括了 组呼业务配置和组呼系统信息广播。 [0114] 组呼信息的下发吋机是终端驻留在源小区的任意吋刻， 此吋将由控制邻小区的 基站向控制源小区的基站共享组呼会话信息， 并在此共享的组呼会话信息相对 之前发生变化吋向终端下发。
[0115] 在一个实施例中， 终端驻留在源小区， 该步骤 230， 包括：
[0116] 从邻小区共享至源小区的组呼信息提取源小区中组呼会话对应的组呼信息， 并 通过群组广播向终端下发。
[0117] 邻小区中进行的组呼会话为一个或者多个， 与之相对应的， 邻小区将为一个或 者多个组呼会话分别配置对应的组呼信息， 因此， 其共享至源小区的组呼信息 也将是一个或者多个组呼会话对应的组呼信息。
[0118] 一方面， 对于源小区而言， 邻小区所共享的组呼信息虽包括了空闲态的终端在 源小区进行组呼会话所对应的组呼信息， 但也包括了其它组呼会话对应的组呼 信息， 因此， 在需要对邻小区共享的组呼信息进行筛选。
[0119] 另一方面， 邻小区已经共享至源小区的组呼信息， 当前所共享的组呼信息相对 此组呼信息， 即空闲态的终端已有的邻小区共享的组呼信息， 发生了变化， 需 要感知此变化， 以进行空闲态的终端中邻小区共享的组呼信息的更新。
[0120] 具体的， 邻小区共享的组呼信息的筛选包括了信息提取和信息比对两个过程， 即步骤 231和步骤 233的执行。
[0121] 根据源小区中的组呼会话， 在邻小区共享的组呼信息提取此组呼会话在邻小区 所对应的组呼信息， 如前所述的， 该组呼信息即为空闲态的终端在邻小区接入 与其在源小区相同的组呼会话所需要的空口资源配置。
[0122] 进一步的， 步骤 230如图 4所示， 包括：
[0123] 步骤 231， 将从邻小区共享至源小区的组呼信息与源小区的组呼会话对比， 得 到与源小区的组呼会话对应的组呼信息， 并提取。
[0124] 步骤 233， 通过群组广播向终端下发提取的组呼信息。
[0125] 进一步的， 对于空闲态的终端已有的邻小区共享的组呼信息， 源小区的基站需 对此进行更新， 即步骤 230如图 5所示， 包括：
[0126] 步骤 235， 判断从邻小区共享至源小区的组呼信息是否发生变化， 若为是， 则 进入步骤 237， 若为否， 则结束。 [0127] 在提取得到源小区中的组呼会话在邻小区的组呼信息之后， 将比对提取的组呼 信息与上一次为此组呼会话下发的组呼信息， 以判断提取的组呼信息是否发生 变化， 若为是， 则说明邻小区中为此组呼会话所进行的空口资源配置发生了变 化， 需要对此进行更新， 以保证保存至非话权终端本地的组呼信息是有效的。
[0128] 步骤 237， 提取组呼信息。
[0129] 步骤 239， 通过群组广播向驻留在源小区的终端下发组呼信息。
[0130] 通过此过程， 使得源小区中空闲态的终端能够保存其在邻小区进行相同组呼会 话所必须的组呼信息， 进而使得终端发生移动吋保证了组呼会话的连续性。
[0131] 下面结合一个具体的实施例来详细阐述如上所述的方法。 该实施例中， 宽带集 群系统包括了核心网、 基站系统以及驻留在基站系统控制的任意小区的终端。
[0132] 此终端为多个， 其可分布于一个或者多个小区中， 是按照一定规则形成的一组 终端， 其中， 终端也划分为话权终端和非话权终端两大类， 话权终端将寻呼所 有非话权终端， 以实现组呼会话。 非话权终端即为前述所指的空闲态的终端。
[0133] 话权终端向核心网发起组呼会话吋， 驻留了非话权终端的源小区将在相应基站 的控制下执行组呼会话建立的信令流程， 并在此过程中源小区和邻小区相应为 此组呼会话创建组呼上下文和配置组呼信息。
[0134] 完成非话权终端在源小区的组呼会话建立之后， 如图 6所示的吋序过程， 控制 源小区的基站将向驻留在源小区的非话权终端周期性下发组呼信息， 以使源小 区中空闲态下的非话权终端根据组呼信息进行组呼会话的配置， 即执行步骤 320
[0135] 在后续非话权终端驻留在源小区的过程中， 源小区与其所对应的邻小区之间将 通过基站的接口进行组呼信息的共享。 相对源小区而言， 需要将邻小区为组呼 会话所配置的组呼信息共享至源小区， 由此并对此进行筛选， 以得到非话权终 端在邻小区进行当前组呼会话的组呼信息， 以待非话权终端进行源小区和邻小 区之间移动中能够直接通过组呼信息在邻小区接入当前组呼会话， 即执行步骤 3 50。
[0136] 通过如上所述的过程， 使得组呼会话中空闲态下的非话权终端能够在不同小区 之间的移动中保持其组呼会话的连续性。 [0137] 也就是的， 如上所述的宽带集群系统中的移动性控制方法应用于组呼会话下处 于空闲态的非话权终端移动到同一基站其它具有相同组呼会话的小区， 也能够 应用于非话权终端移动到邻基站具有相同组呼会话的小区。
[0138] 由此将大大减少了处于空闲态的非话权终端移动产生的信令幵销。
[0139] 在一个实施例中， 还相应提供了一种终端， 该终端为处于组呼会话中空闲态的 终端， 如图 7所示， 该终端包括组呼信息接收模块 410、 小区重选发起模块 430、 信息获取模块 450和接入模块 470， 其中：
[0140] 组呼信息接收模块 410， 用于接收驻留的源小区发送的组呼信息， 组呼信息包 含邻小区的组呼信息。
[0141] 小区重选发起模块 430， 用于发起小区重选得到目标小区。
[0142] 信息获取模块 450， 用于从邻小区中的组呼信息中获取目标小区的组呼信息。
[0143] 接入模块 470， 用于根据目标小区的组呼信息接入目标小区中进行的组呼会话
[0144] 其中， 目标小区是源小区的邻小区， 并且目标小区和源小区均预先为组呼会话 创建了相同的组呼上下文。
[0145] 在一个实施例中， 终端还包括信息筛选模块。 该信息筛选模块用于筛选接收的 组呼信息是否是终端所在组呼会话信息， 若为是， 则保存接收的组呼信息。
[0146] 在一个实施例中， 组呼信息包括组呼业务配置和组呼系统信息广播， 该接入模 块 470如图 8所示， 包括提取单元 471和配置生效单元 473， 其中：
[0147] 提取单元 471， 用于提取组呼信息中的组呼业务配置和组呼系统信息广播。
[0148] 配置生效单元 473， 用于生效所述组呼业务配置， 并根据组呼系统信息广播接 入目标小区， 进而接入目标小区中与其在源小区相同的组呼会话。
[0149] 在一个实施例中， 还相应地提供了一种基站系统， 该基站系统包括控制源小区 和目标小区的基站， 组呼会话中空闲态的终端至少驻留在所述源小区， 所述基 站如图 9所示， 包括组呼会话创建模块 510、 共享接收模块 530和下发模块 550， 其中：
[0150] 组呼会话创建模块 510， 用于为源小区的组呼会话创建组呼上下文并配置组呼 会话的组呼信息。 [0151] 共享接收模块 530， 用于接收邻小区的基站共享的组呼信息， 组呼信息包括邻 小区为组呼会话配置的组呼信息。
[0152] 下发模块 550， 用于通过群组广播向终端下发邻小区为组呼会话配置的组呼信 息。
[0153] 在此基础上， 空闲态的终端根据组呼信息在邻小区接入与其在源小区相同的组 呼会话。
[0154] 在一个实施例中， 下发模块 550进一步用于从邻小区共享至源小区的组呼信息 提取源小区中组呼会话对应的组呼信息， 并通过群组广播向终端下发。
[0155] 在另一个示例性实施例中， 下发模块 550如图 10所示， 包括比对单元 551和下发 执行单元 553。
[0156] 对比单元 551， 用于将从邻小区共享至源小区的组呼信息与源小区的组呼会话 对比， 得到与源小区的组呼会话对应的组呼信息， 并提取；
[0157] 下发执行单元 553， 用于通过群组广播向终端下发提取的组呼信息。
