Description

一种识别 IUR接口传输承载能力的方法及系统 技术领域
本发明涉及无线通讯技术， 尤其涉及一种识别 IUR接口传输承载能力 的方法及系统。 背景技术
高速上行链路分组接入技术通过快速调度以及物理层快速重传合并等 手段来改善上行链路分组数据的性能， 高速上行链路分组接入技术 1入一 种新的传输信道一增强型专用信道（ enhanced Dedicated Channel, E-DCH ), 用于承载用户数据， 且为单上行方向。 专用媒体接入控制 （ Media Access Control- dedicated, MAC-d )协议数据单元 ( Protocol Data Unit, PDU ) 映 射到增强型专用信道的数据流， 称为专用媒体接入控制流（MAC-d flow ), 一个终端一般有一个或者多个专用媒体接入控制流（ MAC-d flow )。
在无线通讯系统中， 无线网络控制器之间互联接口一 IUR ( Interconnection ofRNC )接口是无线网络控制器用于同其他无线网络控制 器进行信令和数据交互的接口， 是无线网络子系统之间互联的纽带。 当一 个终端建立了到无线接入网的连接， 并在 IUR接口产生了软切换， 就会用 到多于一个无线网络控制器的资源， 不同的无线网络控制器分别充当不同 的角色， 例如， 服务无线网络控制器和漂移无线网络控制器， 其中， 服务 无线网络控制器为保持终端与核心网的接口连接的无线网络控制器， 负责 核心网和终端之间的数据传送和与核心网的接口信令的转送和接收、 负责 进行无线资源控制、 负责对空中接口的数据进行层二的处理、 以及执行基 本无线资源管理操作， 如切换判决、 外环功率控制和无线接入承载的参数 向空口传输信道参数的转化等； 漂移无线网络控制器是服务无线网络控制 器以外的其他无线网络控制器， 一般控制终端使用的小区， 如果需要， 漂 移无线网络控制器可以进行宏分集合并， 除非终端使用公共传输信道， 漂 移无线网络控制器不会进行终端面数据的层二处理， 而只是将空口数据透 明的通过 IUR接口的路由传递给服务无线网络控制器。 一个终端的漂移无 线网络控制器可以不止一个。
IUR接口在漂移无线网络控制器和服务无线网络控制器之间提供了上 行增强型专用信道的传输方式。 一个 IUR接口成帧协议层数据流对应着一 个终端的一个专用媒体接入控制流（MAC-d flow ) 所承载的数据。 所以， 一个终端对应有一个或者多个 IUR接口成帧协议层数据流。
在单载波高速上行链路分组接入技术中， 一个 IUR接口成帧协议层数 据流由一个 IUR接口传输承载 （ Transport Bearer )来承载， IUR接口成帧 协议层数据流中不需要携带载波标识。 在多载波高速上行链路分组接入技 术中， 一个 IUR接口成帧协议层数据流可以由一个 IUR接口传输承载来承 载， 也可以由多个（个数和多载波的载波个数相同 ) IUR接口传输承载来 载， 当一个 IUR接口成帧协议层数据流由一个 IUR接口传输 载来 载 时， IUR接口成帧协议层数据流中必须携带载波标识， 以区别所承载的数 据在空口所来源于的载波， 这种处理方式称为增强型专用信道上行流复用 ( E-DCH UL Flow Multiplexing )方式，本文中根据逻辑意义称为 "共享 IUR 传输 载" 方式； 当一个 IUR接口成帧协议层数据流由多个 IUR接口传输 承载来承载， 也就是依照一个 IUR接口成帧协议层数据流所承载的数据在 空口所来源于的载波， 每一个载波来源的数据承载在一个 IUR接口传输承 载上， 多个载波来源的数据承载在多个 IUR接口传输承载上 （ IUR接口传 输承载个数和多载波的载波个数相同） 时， IUR接口成帧协议层数据流中 不需要携带载波标识， 这种处理方式称为分开 IUR传输承载（ Separate IUR Transport Bearer )方式。 某个小区的相邻小区可能在漂移无线网络控制器中， 漂移无线网络控 制器需要以临近小区的方式来将在本漂移无线网络控制器中的小区的各个 功能特性的支持能力告知给服务无线网络控制器 , 以供服务无线网络控制 器作相关功能特性的决策， 如是否使用功能特性以及如何使用功能特性等 等。 在漂移无线网络控制器中的小区的各个功能特性的支持能力一般包括：
1 )多小区增强专用信道能力（ Multi Cell E-DCH Capability ), 本文中根 据逻辑意义简称为上行多载波能力。 上行多载波能力指示小区是否支持上 行多载波， 其取值为 "支持" 或者 "不支持"。
2 )增强型专用信道上行流复用 （ E-DCH UL Flow Multiplexing ) 能力， 本文中根据逻辑意义简称为共享 IUR传输承载能力。 共享 IUR传输承载能 力指示小区是否支持共享 IUR传输承载，其取值为 "支持"或者 "不支持"。 小区支持共享 IUR传输承载， 则意味着此小区支持一个 IUR接口成帧协议 层数据流由一个 IUR接口传输承载来承载， 且 IUR接口成帧协议层数据流 中必须携带载波标识； 小区不支持共享 IUR传输承载， 则意味着此小区不 支持一个 IUR接口成帧协议层数据流由一个 IUR接口传输承载来承载， 或 者不支持 IUR接口成帧协议层数据流中携带载波标识的操作。
3 )分开 IUR传输 载能力 （ Separate IUR Transport Bearer Capability ), 取值为 "支持" 或者 "不支持"， 小区支持分开 IUR传输承载能力， 则意味 着此小区支持一个 IUR接口成帧协议层数据流由多个 IUR接口传输承载来 承载；小区不支持分开 IUR传输承载能力，则意味着此小区不支持一个 IUR 接口成帧协议层数据流由多个 IUR接口传输承载来承载。
现有多载波高速上行链路分组接入技术中， 每一层载波均有自己独立 的宏分集， 独立进行软切换， 加入软切换的宏分集中的各个小区有可能是 支持上行多载波操作的小区， 也有可能是不支持上行多载波操作的小区， 如传统的单载波小区。 对于一个指定的终端而言， 这个终端的各个载波的 各个软切换的宏分集中各个小区，均需要有同样的 IUR传输承载支持能力， 终端的各个载波的各个软切换的宏分集中各个小区均支持 "分开 IUR传输 承载" 处理方式， 或者终端的各个载波的各个软切换的宏分集中各个小区 均支持 "共享 IUR传输承载" 处理方式， 才能够进行软切换中正常的数据 重排序和合并处理， 否则， 服务无线网络控制器将无法将 IUR传输承载支 持能力不同的小区加入软切换的宏分集合中， 例如， 漂移无线网络控制器 中的一个使用多载波高速上行链路分组接入技术的小区支持 "上行多载 波"， 且支持 "共享 IUR传输承载" 处理方式， 但不支持 "分开 IUR传输 承载" 处理方式， 如果服务无线网络控制器为了在这个小区的这个载波上 作软切换， 需要在软切换的宏分集中加入一个传统的单载波的小区， 而由 于该传统的单载波的小区不支持 "共享 IUR传输承载" 处理方式， 服务无 线网络控制器将无法把此传统的单载波的小区加入软切换的宏分集， 从而 会影响系统性能， 减小软切换的宏分集合增益。 发明内容
有鉴于此， 本发明的主要目的在于提供一种识别 IUR接口传输承载能 力的方法及系统， 能够提高系统性能， 增大软切换的宏分集合增益。
为达到上述目的， 本发明的技术方案是这样实现的：

上述方案中， 所述服务无线网络控制器判断小区是否支持 "上行多载 波" 之前还包括步骤： 服务无线网络控制器接收来自漂移无线网络控制器的关于所述小区 "上行多载波能力" 的支持能力信息， 并进行解析。
所述小区在漂移无线网络控制器中。
上述方案中， 漂移无线网络控制器将所述小区 "上行多载波能力" 的 支持能力信息作为邻近小区的支持能力信息， 发送给服务无线网络控制器。
一种识别 IUR接口传输承载能力的系统， 该系统包括判断单元和识别 单元， 所述判断单元和识别单元均位于服务无线网络控制器中，
所述判断单元， 用于判断小区是否支持 "上行多载波"， 并将判断结果 发送至识别单元；
所述识别单元， 用于在小区支持 "上行多载波" 时， 识别所述小区为 支持使用 "分开 IUR传输承载"处理方式且支持使用 "共享 IUR传输承载" 处理方式的小区； 以及在小区不支持 "上行多载波" 时， 识别所述小区为 支持使用 "分开 IUR传输承载" 处理方式且不支持使用 "共享 IUR传输承 载" 处理方式的小区。
上述方案中， 该系统还包括漂移无线网络控制器和位于服务无线网络 控制器中的接收&解析单元，
所述漂移无线网络控制器， 用于向服务无线网络控制器发送关于小区 "上行多载波能力" 的支持能力信息；
所述接收&解析单元， 用于接收来自漂移无线网络控制器的关于小区 "上行多载波能力" 的支持能力信息， 并进行解析， 之后将解析结果发送 至判断单元；
所述判断单元，还用于根据来自接收&解析单元的解析结果来判断小区 是否支持 "上行多载波"。
所述小区在漂移无线网络控制器中。
上述方案中， 所述漂移无线网络控制器向服务无线网络控制器发送关 于小区 "上行多载波能力" 的支持能力信息为： 漂移无线网络控制器将所 述小区 "上行多载波能力" 的支持能力信息作为邻近小区的支持能力信息， 发送给服务无线网络控制器。
本发明识别 IUR接口传输承载能力的方法及系统， 对于漂移无线网络 控制器中支持 "上行多载波" 的小区， 服务无线网络控制器识别此小区为 支持使用 "分开 IUR传输承载"处理方式且支持使用 "共享 IUR传输承载" 处理方式的小区； 对于漂移无线网络控制器中不支持 "上行多载波" 的小 区， 服务无线网络控制器识别此小区为支持使用 "分开 IUR传输承载" 处 理方式且不支持使用 "共享 IUR传输承载" 处理方式的小区。 由于本发明 将不支持 "上行多载波" 的小区识别为支持使用 "分开 IUR传输承载" 处 理方式且不支持使用 "共享 IUR传输承载"处理方式的小区，使不支持 "上 行多载波" 的小区有可能与支持 "上行多载波" 的小区加入同一个软切换 的宏分集， 从而提高系统性能， 增大软切换的宏分集合增益。 附图说明
图 1为本发明识别 IUR接口传输承载能力的方法流程示意图； 图 2为本发明实施例 1识别 IUR接口传输承载能力的方法流程示意图； 图 3为本发明实施例 2识别 IUR接口传输承载能力的方法流程示意图。 具体实施方式
本发明的基本思想是： 对于漂移无线网络控制器中支持 "上行多载波" 的小区， 服务无线网络控制器识别此小区为支持使用 "分开 IUR传输承载" 处理方式且支持使用 "共享 IUR传输承载" 处理方式的小区； 对于漂移无 线网络控制器中不支持 "上行多载波" 的小区， 服务无线网络控制器识别 此小区为支持使用 "分开 IUR传输承载"处理方式且不支持使用 "共享 IUR 传输承载" 处理方式的小区。 图 1为本发明识别 IUR接口传输承载能力的方法流程示意图， 如图 1 所示， 本发明识别 IUR接口传输承载能力的方法包括以下步骤：
步骤 101 :服务无线网络控制器接收来自漂移无线网络控制器的关于小 区 "上行多载波能力" 的支持能力信息。
一般的， 所述小区在漂移无线网络控制器中， 漂移无线网络控制器向 服务无线网络控制器发送关于所述小区 "上行多载波能力" 的支持能力信 息的背景为： 所述小区作为某个小区的邻近小区， 漂移无线网络控制器将 此小区的 "上行多载波能力" 的支持能力信息作为邻近小区的支持能力信 息， 发送给服务无线网络控制器。
步骤 102: 服务无线网络控制器解析接收到的关于小区 "上行多载波能 力" 的支持能力信息。
步骤 103: 服务无线网络控制器判断所述小区是否支持 "上行多载波"， 如果是， 执行步骤 104; 否则， 转到步骤 105。
步骤 104: 服务无线网络控制器识别所述小区为支持使用 "分开 IUR 传输承载" 处理方式且支持使用 "共享 IUR传输承载" 处理方式的小区。
这里， "上行多载波能力" 的支持能力信息为 "支持"。
步骤 105: 服务无线网络控制器识别所述小区为支持使用 "分开 IUR 传输承载" 处理方式且不支持使用 "共享 IUR传输承载" 处理方式的小区。
这里， "上行多载波能力" 的支持能力信息为 "不支持"。
本发明中， 对于漂移无线网络控制器中支持 "上行多载波" 的小区， 服务无线网络控制器识别此小区为支持使用 "分开 IUR传输承载" 处理方 式且支持使用 "共享 IUR传输承载" 处理方式的小区； 对于漂移无线网络 控制器中不支持 "上行多载波" 的小区， 服务无线网络控制器识别此小区 为支持使用 "分开 IUR传输承载" 处理方式且不支持使用 "共享 IUR传输 承载" 处理方式的小区， 原因为： 对于传统的单载波小区， 也就是在单载波高速上行链路分组接入技术 中， 在这一层载波上， 一个 IUR接口成帧协议层数据流由一个 IUR接口传 输承载来承载， IUR接口成帧协议层数据流中不需要携带载波标识， 所以， 传统的单载波小区可以视为支持 "分开 IUR传输承载" 处理方式。 对于支 持 "上行多载波" 的小区， "分开 IUR传输承载" 处理方式和 "共享 IUR 传输承载" 处理方式均为一种软件的处理方式， 并不受到任何硬件或者射 频资源所确定的一个硬性限定。从软件的角度， "分开 IUR传输承载"处理 方式和 "共享 IUR传输承载" 处理方式均可以以很低成本实现， 从后向兼 容性的角度， 支持 "上行多载波" 的小区， 也可以作为一个传统单载波的 小区进行资源利用和使用， 所以， 从服务无线网络控制器的角度， 对于支 持 "上行多载波" 的小区可以理解为： 在单载波前期技术阶段， 可以看作 支持 "分开 IUR传输承载" 处理方式； 在多载波后期技术阶段， 可以看作 更进一步的支持一种更高的 "共享 IUR传输承载" 处理方式， 换言之， 从 服务无线网络控制器的角度， 可以把支持 "分开 IUR传输承载" 处理方式 看作一种在单载波技术阶段就具备的一定需要支持的能力， 把 "共享 IUR 传输承载" 处理方式看作一种在多载波技术阶段才引入的更高级的支持的 能力。 这样的话， 服务无线网络控制器可以没有任何障碍的进行软切换加 入新的小区， 对于宏分集中有传统的单载波的小区， 服务无线网络控制器 可以控制使用 "分开 IUR传输承载" 处理方式； 对于宏分集中全部为支持 上行多载波能力的小区， 服务无线网络控制器可以依照一定的算法决定控 制使用 "分开 IUR传输承载"处理方式或者控制使用 "共享 IUR传输承载" 处理方式。 这样， 就可以解决现有技术中的处理漏洞。
本发明还提出一种识别 IUR接口传输承载能力的系统， 该系统包括判 断单元和识别单元， 所述判断单元和识别单元均位于服务无线网络控制器 中， 判断单元， 用于判断小区是否支持 "上行多载波"， 并将判断结果发送 至识别单元；
识别单元， 用于在小区支持 "上行多载波" 时， 识别所述小区为支持 使用 "分开 IUR传输承载" 处理方式且支持使用 "共享 IUR传输承载" 处 理方式的小区； 以及在小区不支持 "上行多载波" 时， 识别所述小区为支 持使用 "分开 IUR传输承载"处理方式且不支持使用 "共享 IUR传输承载" 处理方式的小区。
该系统还包括漂移无线网络控制器和位于服务无线网络控制器中的接 收 &解析单元，
漂移无线网络控制器， 用于向服务无线网络控制器发送关于小区 "上 行多载波能力" 的支持能力信息；
接收 &解析单元， 用于接收来自漂移无线网络控制器的关于小区 "上行 多载波能力" 的支持能力信息， 并进行解析， 之后将解析结果发送至判断 单元；
判断单元，还用于根据来自接收&解析单元的解析结果来判断小区是否 支持 "上行多载波"。
这里， 所述小区在漂移无线网络控制器中。
漂移无线网络控制器向服务无线网络控制器发送关于小区 "上行多载 波能力" 的支持能力信息为： 漂移无线网络控制器将所述小区 "上行多载 波能力" 的支持能力信息作为邻近小区的支持能力信息， 发送给服务无线 网络控制器。
由于本发明在小区各个功能特性的支持能力中， 去掉了 "共享 IUR传 输承载能力" 和 "分开 IUR传输承载能力"， 全部通过 "上行多载波能力" 的支持能力信息的解析来识别小区的支持能力， 能够避免配置导致的理解 歧义。 下面结合具体实施例对技术方案的实施作进一步的详细描述。
实施例 1
本实施例中， 小区 1在服务无线网络控制器 1中， 小区 2在漂移无线 网络控制器 2中， 小区 2是小区 1的邻近小区， 小区 2的 "上行多载波能 力" 的支持能力信息为 "支持"。 图 2为本发明实施例 1识别 IUR接口传输 承载能力的方法流程示意图， 如图 2所示， 该方法包括以下步骤：
步骤 201 :服务无线网络控制器 1接收到由漂移无线网络控制器 2发出 的小区 2的 "上行多载波能力" 的支持能力信息为 "支持"。
这里， 小区 2在漂移无线网络控制器 2中， 小区 2作为小区 1的邻近 小区，漂移无线网络控制器 2将邻近小区 (也就是小区 2 )的支持能力信息， 包括 "上行多载波能力" 的支持能力信息为 "支持"， 通知给服务无线网络 控制器 1。
步骤 202: 服务无线网络控制器 1解析所述 "上行多载波能力" 的支持 能力信息为 "支持"， 则服务无线网络控制器 1识别在漂移无线网络控制器 2中的小区 2为支持使用 "分开 IUR传输承载" 处理方式且支持使用 "共 享 IUR传输承载" 处理方式的小区。 实施例 2
本实施例中， 小区 1在服务无线网络控制器 1中， 小区 2在漂移无线 网络控制器 2中。 小区 2是小区 1的邻近小区。 小区 2的 "上行多载波能 力" 的支持能力信息为 "不支持"。 图 3为本发明实施例 2识别 IUR接口 传输承载能力的方法流程示意图， 如图 3所示， 该方法包括以下步骤： 步骤 301 :服务无线网络控制器 1接收到由漂移无线网络控制器 2发出 的小区 2的 "上行多载波能力" 的支持能力信息为 "不支持"。
这里， 小区 2在漂移无线网络控制器 2中， 小区 2作为小区 1的邻近 小区，漂移无线网络控制器 2将邻近小区 (也就是小区 2 )的支持能力信息， 包括 "上行多载波能力" 的支持能力信息为 "不支持"， 通知给服务无线网 络控制器 1。
步骤 302: 服务无线网络控制器 1解析 "上行多载波能力" 的支持能力 信息为 "不支持"， 则识别所述在漂移无线网络控制器 2中的小区 2为支持 使用 "分开 IUR传输承载"处理方式， 但不支持使用 "共享 IUR传输承载" 处理方式的小区。
以上所述， 仅为本发明的较佳实施例而已， 并非用于限定本发明的保 护范围。
