Description

一种宽带码分多址系统实现上行宏分集
的方法
技术领域 本发明涉及移动通讯宽带码分多址( WCDMA, Wideband Code Division Multiple Access ) 系统的软切换技术, 尤其涉及 WCDMA系统在 ' j、区软切换 过程中实现上行宏分集的方法。 背景技术 第三 移动通讯伙伴计划(3GPP, 3rd Generation partnership project )在 其 R7版本的协议中提出了新的网络架构,如图 1所示,引入了新的网元 演进的高速分组接入 B 节点 (eHSPA NodeB , evolved High Speed Packet Access NodeB )。 在这种架构下,对于分组交换( PS , Packet Switched )业务, eHSPA NodeB 集成了无线网络控制器 (RNC, Radio Network Controller ) 的功能, 并与 PS 核心网 (CN, Core Network ) 的网关通用分组无线业务支撑节点 (GGSN, Gateway General packet radio service support node ) 以及月 务通用分组无线业 务支撑节点 ( SGSN, Serving General packet radio service Support Node )相连; eHSPA NodeB与传统 RNC以及 eHSPA NodeB之间都是通过 lur口连接。 lur 接口是 WCDMA 系统是无线网络子系统 (RNS , Radio Network Subsystem )之间互联的纽带。 通过 lur接口, 不同的 RNS可以连在一起, 通 过专用的十办议 无线网络子系统应用部分 ( RNSAP , Radio Network
Subsystem Application Part ) 完成连接无线接入网路 ( RAN, Radio Access Network ) 的用户设备(UE, User Equipment )跨 RNS的移动性管理, 包括 RNS间的切换、 无线资源处理和同步等功能。
3GPP提供的跨 lur口 eHSPA NodeB宏分集方案如图 2所示。漂移 eHSPA NodeB ( Drift eHSPA NodeB )将 UE的上行数据通过 lur口发送到月 务 eHSPA NodeB ( Serving eHSPA NodeB ), 再由月 务 eHSPA NodeB 将漂移 eHSPA NodeB发送的数据与服务 eHSPA NodeB收到的 UE的上行数据合并后发给核 心网。 由于空中接口技术的演进导致空中接口速率越来越高,同时新的网络架 构下会出现大量的跨 lur口的切换,这样按照 3GPP已有的基于无线链路( RL, Radio Link ) 的宏分集策略, 在某些情况下就不能满足获得宏分集增益和降 低 lur口带宽利用率兼顾的要求。 如 IP电话 ( VOIP, Voice over IP ) 和大速 率的 PS数据业务并发的情况。 如果采用跨 lur口的宏分集, 则大速率的 PS 数据业务会给 lur 口的传输带来较大的带宽压力; 而如果不采用宏分集, 又 不能获得宏分集增益,这对于业务质量尤其是对时延要求较高的 IP电话影响 会比较大。 这样如何在保证宏分集增益的前提下尽量减少 lur 口数据传输的 压力是 3GPP面临的一个课题。 本文中是否跨 lur口宏分集与是否建立 lur口 传输承载是等价的。 发明内容 本发明所要解决的技术问题是提供一种宽带码分多址系统实现上行宏 分集的方法, 通过对 lur 口协议进行很小的改动即可达到兼顾宏分集增益和 尽量减少 lur口传输压力的目的。 为了解决上述技术问题,本发明提供了一种宽带码分多址系统实现上行 宏分集的方法, 包括如下步骤:
( a ) 在建立 lur口传输承载的信元中增加一个传输承载建立指示信元, 所述传输承载建立指示信元用于指示本传输信道是否建立传输承载;
( b )服务演进的高速分组接入 B节点通过无线链路建立消息, 建立 lur 链路上的各承载; 漂移演进的高速分组接入 B节点根据服务演进的高速分组 接入 B节点的指示分配 lur口的传输资源并返回响应消息。 优选地, 上述方法还包括步骤 (c ): 服务演进的高速分组接入 B 节点 根据 lur 口传输资源的使用情况动态重配承载, 漂移演进的高速分组接入 B 节点根据服务演进的高速分组接入 B节点的指示重新分配 lur口的传输资源。 优选地, 上述步骤( a )中, lur口传输承载的信元包括 RL Specific DCH
Information及 RL Specific E-DCH Informatior 优选地, 上述步骤 (a ) 中, 传输信道包括专用传输信道和增强的专用 传输信道流中的一种或多种。 优选地, 上述步骤 (a ) 中, 传输承载建立指示信元的取值包括: 建立 承载、 不建立承载。 优选地, 上述步骤 (a ) 中, 当传输承载建立指示信元的取值为不建立 传输 载时, 传输信道对应的信元 Binding ID和 Transport Layer Address不 在步骤 ( b ) 中的无线链路建立消息中出现。 优选地, 步骤 (b ) 中, 服务演进的高速分组接入 B节点根据 lur口链 路上的各 载的不同 务质量参数决定相应的宏分集策略, 并指示漂移演进 的高速分组接入 B节点是否建立传输承载。 优选地, 步骤( b ) 中, 将服务质量参数接近的业务复用在同一传输信 道上, 并对其采用相同的宏分集策略, 建立或不建立传输承载。 优选地, 上述方法对于 RNC与 eHSPA NodeB之间的 lur口以及 RNC 之间的 lur口同样适用, 并且对于 Iub口也适用。 本发明具有以下优点或有益效果:只需在现有流程中增加信元即可指示 承载的 lur 口传输承载是否建立, 对现有流程影响很小; 可以实现对用户基 于 lur 口不同承载选择不同的宏分集策略, 以达到既能使业务获得宏分集增 益又能降氏 lur口数据流量的目的;可以才艮据 lur口带宽的实际利用情况动态 调整 lur口承载的宏分集策略,使系统的 lur口利用率和宏分集性能达到最优 化。 附图说明 图 1是才艮据相关技术的 3GPP的 R7版本与 R7版本之前的网元共同组 网的示意图; 图 2是才艮据相关技术的 3GPP提供的跨 lur口 eHSPA NodeB宏分集方案 示意图; 图 3是根据本发明实施例的 lur不同承载建立不同宏分集策略的信令流 程图。 具体实施方式 本发明的核心思路是针对同一 UE上的 lur口的不同承载采用不同的宏 分集策略, 以达到兼顾宏分集增益和降低 lur 口带宽压力的目的。 具体做法 是为月 务 eHSPA NodeB 在建立 lur 口传输 载的信元 ( RL Specific DCH Information, RL Specific E-DCH Information ) 中增力口一个用于指示本传输 载是否建立的信元, 取值可以为不建立传输承载、 建立传输承载。 如果取值 为建立传输 载, 则通过 Binding ID、 Transport Layer Address信元标 i只传输 层地址。如果取值为不建立传输 载, 贝l Binding ID、 Transport Layer Address 信元不必出现。 本发明可以才艮据 lur 口的带宽的实际利用情况动态调整 lur 口承载的宏分集策略, 使系统的 lur口利用率和宏分集性能得到最优化。 下面结合实施例和附图对本发明上述技术方案作进一步的详细描述。 目前协议规定 lur 口承载都是以传输信道为单位来维护的, 对于 3GPP
R6 前的版本, 可进行宏分集的 lur 口的上行传输信道称之为专用传输信道 ( DCH , Dedicated Channel ); 对于 R6及以后的版本, 除了 DCH信道, 还 支持增强的上行专用传输信道 MAC-d流的宏分集 (E-DCH MAC-d flow, Enhanced uplink DCH MAC-d flow )。 由于每个 DCH、 E-DCH MAC-d flow有 特定的 Qos参数, 如 DCH调度优先级, E-DCH的重传次数、 功率偏移等; 一般只有 Qos接近的业务才能复用在同一个传输信道上, 否则就是对网络容 量的一种浪费。 由于 Qos接近的业务可以采用同样的宏分集策略, 因此可以 基于 lur口的不同传输信道采用建立或不建立 lur口传输 载。 对目前 lur 口十办议的改动主要是 RL Specific DCH Information , RL Specific E-DCH Information信元, 如表 1、 表 2中的黑体字所示。 表 1
Figure imgf000006_0001
正如表 1、 表 2中所表示的, 在建立 lur口传输 载的信元 RL Specific DCH Information及 RL Specific E-DCH Information中各增力口一个用于指示本 传输信道对应的传输承载是否建立的信元, 取值为不建立传输承载、 建立传 输承载。 如果取值为建立传输承载, 则该传输信道对应的 Binding ID、 Transport Layer Address信元可以用于标 i只传输层地址。 表 2
Figure imgf000007_0001
漂移 eHSPA NodeB才艮据服务 eHSPA NodeB的指示,对于不需要建立的 lur 口 载, 在其响应消息的 DCH Information Response、 E-DCH FDD Information Response信元中不需要包括 Binding ID和 Transport Layer Address 信元。 才艮据 lur口的带宽使用情况或其他原因, 服务 eHSPA NodeB还可以发 起对 lur口 载的重配过程。 本发明提供的一种宽带码分多址系统实现上行宏分集的方法,包括如下 步骤:
( a ) 在建立 lur口传输承载的信元中增加一个传输承载建立指示信元, 用于指示本传输信道的 lur口承载是否建立传输承载; lur口传输 载的信元包括 RL Specific DCH Information及 RL Specific E-DCH Information; 传输信道包括专用传输信道 DCH和增强的专用传输信 道流 E-DCH MAC-d flow中的一种或多种; 传输承载建立指示信元取值可以 为建立传输承载、 不建立传输承载。
( b )月 务 eHSPA NodeB通过 lur口的无线链路建立消息, 建立 lur链 路上的各 载; 漂移 eHSPA NodeB才艮据月 务 eHSPA NodeB的指示分配 lur 口的传输资源并返回响应消息;
( c )服务 eHSPANodeB 居 lur口传输资源的使用情况动态重配承载, 漂移 eHSPA NodeB才艮据月 务 eHSPA NodeB的指示重新分配 lur口的传输资 源。 图 3所示的控制 lur口宏分集策略信令流程给出了本发明方法的一实施 例。 该信令流程包括如下步骤: 步骤一: 用户需要建立一条 lur口链路, 包括一条 DCH的传输承载、 两条 E-DCH Mac-d flow的传输承载。 才艮据各承载上业务对应的 Qos不同, 月 务 eHSPA NodeB通过 lur口的无线链路建立消息指示: DCH采用宏分集, 建立 lur口传输 载; E-DCH Mac-d flow 1采用宏分集,建立 lur口传输 载; E-DCH Mac-d flow2 不采用宏分集, 不建立 lur 口传输 载, 与之对应的 Binding ID和 Transport Layer Address也不需要出现; 步骤二: 漂移 eHSPA NodeB才艮据服务 eHSPA NodeB的指示分配 lur口 的传输资源并返回响应消息。 其中对于 E-DCH Mac-d flow2不需要包含承载 信息 (这里的 载信息就是指 Binding ID和 Transport Layer Address ); 步骤三: 由于 lur口传输资源紧张, 服务 eHSPA NodeB决定释放一些 lur口的资源, 通过重配过程爹改 E-DCH Mac-d flowl的传输 载为不建立; 步骤四: 漂移 eHSPA NodeB 才艮据服务 eHSPA NodeB 的指示释放掉
E-DCH Mac-d flowl的传输 载; 步骤五: 当 lur口传输资源緩解, 服务 eHSPA NodeB决定恢复 E-DCH Mac-d flowl的 lur口传输承载; 步骤六: 漂移 eHSPA NodeB才艮据服务 eHSPA NodeB的指示为 E-DCH Mac-d flowl分配传输 载并将 E-DCH Mac-d flowl的传输地址通过响应消 息传递给月 务 eHSPA NodeB。 需要说明的是, 上述方法实现简单, 易于推广到 RNC与 eHSPA NodeB 之间的 lur口以及 RNC之间的 lur口; 且其原理对 Iub口也同样适用。 本发明实施例只需对现有流程进行很小改动就能实现对用户基于 lur口 不同承载选择不同的宏分集策略, 以达到兼顾使业务获得宏分集增益和降低 lur口数据流量的目的。 另夕卜, 本发明可以根据 lur口带宽的实际利用情况动 态调整 lur口承载的宏分集策略,使系统的 lur口利用率和宏分集性能达到最 优化。 虽然本发明已以较佳实施例揭露如上, 然其并非用以限定本发明, 任何 熟习此技艺者,在不脱离本发明的精神和范围内, 当可作些许的更动与润饰, 因此本发明的保护范围当以前述权利要求书所界定者为准。
