Description

多载波系统中增强小区前向接入信道的资源配置设备及方法
技术领域
本发明涉及一种增强小区前向接入信道( CELL FACH )的资源配置方法, 尤其涉及一种多载波系统中增强小区前向接入信道的资源配置设备及方法。
背景技术
目前第三代移动通信伙伴组织 (3GPP ) 完成了宽带码分多址接入 ( WCDMA ) 系统中 CELL— FACH状态增强的标准化工作。 CELL— FACH状 态增强通过在 CELL— FACH状态引入高速下行共享信道(HS-DSCH, High Speed Downlink Shared Channel )和增强上行专用信道 ( E-DCH, Enhanced uplink DCH )来增强 CELL— FACH状态下的分组数据传输性能, 以获得较小 的分组传输时延和较高的传输速率。
在引入增强 CELL— FACH功能后, 在 CELL— FACH状态下, 数据和控制 消息可以映射到 HS-DSCH和 E-DCH上传输。 为了支持这种传输, 在 Iub接 口需要预配置 CELL— FACH状态下使用的 HS-DSCH和 E-DCH资源信息, 包 括 Iub口的传输承载及 HS-DSCH、 E-DCH相关的资源。
在现有系统中, 无线网络控制器(RNC )通过物理共享信道重配置过程 为节点 B ( Node B ) 配置小区内的 HS-DSCH、 E-DCH资源池。 目前的配置 方式, 一种是 RNC来分割小区内的 HS-DSCH、 E-DCH资源, 一部分用于小 区专用信道(CELL— DCH )状态, 另一部分用于 CELL— FACH状态, 由于该 配置方式基本是固定配置方式, 专用状态下的 UE (用户终端 )和前向接入状 态下的 UE所分配的资源是固定, 当其中一种 UE的资源紧张时,也不可能获 得较多的资源分配, 不利于资源共享。 另一种方法是由 Node B 来分割 HS-DSCH, E-DCH资源, Node B同样将 RNC预配置的资源池分割成两部分, 不同的是, 该两部分资源可以半静态调整。 然而由于 Node B对小区内 UE数 量掌握有限, 所分出的资源不一定是最优化的。 这同样解决不了资源分配不 合理的矛盾, 从而导致资源的利用率较低。 发明内容

图 1为本发明实施例多载波系统中增强小区前向接入信道的资源配置方 法的流程示意图。
本发明的较佳实施方式
下面将结合附图及实施例对本发明的技术方案进行更详细的说明。
由于 RNC可准确的确定小区中 CELL— FACH状态下的 UE数量, 因此可 针对 UE数量来合理分配小区中 CELL— FACH状态下的信道资源, 同时, 可 根据 Node B上报的其所支持的频点信息,决定 CELL— FACH状态下的信道资 源的承载频点, 这更有利于多载波通信系统的资源配置, 从而提高了系统的 资源利用率。 另外, 本发明通信系统的 RNC在进行信道配置时, 同时设置信 道资源池的公共 MAC流信息, 以便 Node B对 CELL— FACH状态下的数据流 量进行监控, 在数据流量较大超过 Node B的承载极限时, 通知 RNC减少或 停止数据传送, 以避免数据的丟失, 从而提高了系统的稳定性。
为使本发明的目的、 技术方案和优点更加清楚明白, 以下举实施例并参 照附图, 对本发明进一步详细说明。
本实施例提供一种多载波系统中增强小区前向接入信道的资源配置设 备, 包括: RNC、 Node B及 UE;
RNC 用于根据小区中增强 CELL— FACH 的 UE 数量确定需配置
HS-DSCH, E-DCH相关资源的频点数及频点信息, 并通过高速物理共享信道 重配置消息通知 Node B; 还用于在高速物理共享信道重配置消息中向节点 B 发送公共 MAC流标识与公共 EMAC流标识; 以及收到高速物理共享信道重 配置响应消息后,为各用户终端指定使用的载波信息及该载波上的 HS-DSCH 相关资源与 E-DCH相关资源, 并通知给 UE。
Node B用于接收高速物理共享信道重配置消息, 解析并保存 RNC确定 的配置增强 CELL— FACH状态下的信道资源的载波数及频点信息, 以及在所 述频点信息对应的载波上配置增强 CELL— FACH状态下的信道资源, 包括高 速下行共享信道 HS-DSCH相关资源和增强上行专用信道 E-DCH相关资源; 还用于为所述载波建立公共 MAC流及公共 EMAC流,并向 RNC返回高速物 理共享信道重配置响应消息, 其中携带为各载波配置的 HS-DSCH相关资源、 E-DCH相关资源和各载波对应的公共 MAC流传输层地址信息、 MAC流标识 信息、 公共 EMAC流传输层地址信息及 EMAC流标识信息。
本实施例提供一种多载波系统中增强小区前向接入信道的资源配置方 法, 如图 1所示, 包括以下步骤:
步骤 101 : RNC根据小区中增强 CELL— FACH的 UE数量确定需配置 HS-DSCH, E-DCH相关资源的频点数及频点信息, 并通过高速物理共享信道 重配置消息通知 Node B。
RNC确定为 CELL— FACH状态下的 UE分配信道资源时, 提取各小区中 支持增强 CELL— FACH的载波信息, 即频点信息。所述频点信息由 Node B向 所述 RNC上报, 该上报过程在 Node B建立调试完毕后即完成了, 上报的方 式可通过审计应答消息或资源状态指示消息来完成, 关于消息的上报, 可参 照协议相关规定。 也就是说, RNC侧存储了各小区所支持载波的信息。
RNC获取待资源分配小区的 UE数量, 根据增强 CELL— FACH状态下的 UE数量确定需要分配的信道资源状况, 例如, UE较多时, 可在小区内的多 个载波上配置 HS-DSCH和 E-DCH相关资源, 以满足小区 UE的数据传输速 率,提高系统的服务质量。在增强 CELL— FACH状态下,用户上行使用 E-DCH 相关资源、 下行使用 HS-DSCH相关资源。 当然, 信道资源的分配方式, 尚 需考虑系统的整体配置、 CELL— DCH状态下的 UE数量情况。 一旦确定所需 配置的频点信息, 则通过高速物理共享信道重配置消息通知 Node B。

其中, "HS-FACH频点信息"就是小区中所支持增强 CELL— FACH状态 下资源池的载波数, 每个小区所支持的载波数可能会有所不同。 "公共 MAC 流标识 "用于标识 CELL— FACH状态下所设置的公共 MAC流, "公共 EMAC 流标识 " 用于标识 CELL— FACH状态下所设置的公共 EMAC流。

步骤 102: Node B根据接收的频点信息, 在所述频点对应的载波上配置 CELL— FACH状态下的 HS-DSCH和 E-DCH相关资源, 并在所述频点对应的 载波上建立公共 MAC流及公共 EMAC流。
Node B收到 RNC所发送的高速物理共享信道重配置消息后, 解析保存 各频点的 HS-DSCH、 E-DCH相关资源的配置信息, 各频点的 HS-DSCH、 E-DCH相关资源的配置信息指需要在哪些载波上分配 HS-DSCH与 E-DCH无 线资源并建立公共 MAC 流、 公共 EMAC 流, 之后根据保存的各载波的 HS-DSCH, E-DCH相关资源的配置信息在相应载波分配 HS-DSCH、 E-DCH 相关资源, 同时, 为各载波建立相关公共 MAC流(包括公共 MAC流及公共 EMAC流) , 以方便 Node B对该载波的 CELL— FACH状态下的数据流量进 行监控。 HS-DSCH相关资源具体包括: HS-DSCH共享控制信道(HS-SCCH ) 、 HS-DSCH 共享指示信道 ( HS-SICH ) 、 高速物理下行链路共享信道 ( HS-PDSCH )等。 E-DCH相关资源池包括: E-DCH绝对授权信道( E-AGCH )、 增强高速指示信道(E-HICH )等。
需要说明的是, 为方便 UE对载波的侦听, 单个 UE所使用的 E-DCH相 关资源和 HS-DSCH相关资源必须配置在同一个载波上, 即在同一载波上需 同时配置 HS-DSCH相关资源与 E-DCH相关资源, 不能只配置 HS-DSCH相 关资源或只配置 E-DCH相关资源。
步骤 103: Node B完成资源配置后, 通过高速物理共享信道重配置响应 消息将配置在各载波的相关资源信息、 各载波对应的公共 MAC 流传输层地 址信息及公共 MAC流标识信息、 各载波对应的公共 EMAC流传输层地址信 息及公共 EMAC流标识信息通知 RNC。
如果 Node B分配资源成功, 则向 RNC返回配置成功的消息, 否则, 返 回配置失败的消息。具体是通过高速物理共享信道重配置响应消息来承载的。
步骤 104: RNC将 Node B所配置 HS-DSCH相关资源的 HS-SCCH、
HS-SICH, E-DCH相关资源的 E-AGCH、 E-HICH分配给各 UE, 即指定 UE 使用哪个载波上的 HS-DSCH相关资源及 E-DCH相关资源, 具体分配方式同 现有技术, 之后 RNC将分配的资源信息通知给 UE。
RNC将 Node B配置成功的 HS-DSCH和 E-DCH相关资源中的 HS-SCCH、 HS-SICH, E-AGCH, E-HICH的相关信息通知给 UE, 也即将承载 HS-SCCH、 HS-SICH, E-AGCH, E-HICH 的频点信息通知给 UE, 以方便 UE 完成对 HS-SCCH, HS-SICH 的侦听, 从而实现 CELL— FACH状态的接入。 为方便 UE对载波的侦听,单个 UE所使用的 E-DCH资源和 HS-DSCH资源配置在同 一个载波上。
本发明中, 将增强 CELL— FACH状态下信道的频点与公共 MAC流相绑 定(即为各载波配置增强 CELL— FACH状态下的信道资源的同时为之建立公 共 MAC流与公共 EMAC流) , 可以达到两个效果: 其一是 RNC向 Node B 指示了频点数及具体的频点信息, 其二是将 MAC流 (包括公共 MAC流与公 共 EMAC流)与频点绑定后, Node B可以按频点进行流量监控, 当某频点所 在载波的数据传输量较大超出 Node B的承载时, 通知 RNC降低向该载频下 发的数据量,反之则通知 RNC增大下发的数据量。在上报资源配置信息的同 时, 还将公共 MAC流传输层地址上报至 RNC, 以方便 RNC完成对 Node B 之间的数据流量控制。
本发明尤其适合于各种多载波系统中, 如时分同步码分多址
( TD-SCDMA, Time Division Synchronous Code Division Multiple Access ) 的 多载波系统中。
当然, 本发明还可有其他多种实施例, 在不背离本发明精神及其实质的 但这些相应的改变和变形都应属于本发明所附的权利要求的保护范围。
工业实用性
釆用本发明的技术方案, 能实现合理地为 CELL— FACH状态下的用户分 配资源,解决了资源分配不合理的矛盾,提高了资源的利用率;而且方便 Node B实现对 CELL— FACH状态下数据流量的监控。
