HSDPA网络的下行部分是多用户设备(User Equipment;以下简称 UE) 同时在高速下行链路共享信道( High-Speed Downlink Shared Channel; 以下 简称 HS-DSCH ) 上传输数据, 因此需要对每个 UE进行标识, 以便不同 UE 都能在数据信道上收到自己的数据。 由控制无线网络控制器 (Control Radio Network Controller; 以下简称 CRNC ) 为不同的 UE 分别配置 HS-DSCH无线网络临时识别符 (HS-DSCH Radio Network Temporary Identity; 以下简称 H-RNTI) , 以标志不同的 UE。 CRNC 同时将 H-RNTI 通知给 Node B和 UE。 UE在高速共享控制信道(High-Speed Shared Control Channel; 以下简称 HS-SCCH)上如果检测到下行数据中的 H-RNTI和配置 的 H-RNTI —致, 就会在对应的高速下行物理链路共享信道 (High-Speed Physical Downlink Shared Channel ; 以下简称 HS-PDSCH) 上接收数据。
本发明实施例的 HSPDA 网络中的无线接入网中包括无线网络控制器 (Radio Network Controller; 以下简称 RNC )与 Node B,其中 RNC与 Node B之间的数据传输按照 FP协议进行数据传输。 下面结合附图及具体实施方
式详细介绍本发明实施例。
本发明实施例提供一种数据传输方法。 该数据传输方法应用于 HSDPA 网络中,包括:根据用户设备的第一 H-RNTI和所述用户设备接入的中继节 点的第二 H-RNTI之间的映射关系,将数据通过所述第二 H-RNTI对应的中 继节点发送给所述第一 H-RNTI对应的用户设备。
例如:在小区边缘引入中继节点 (Relay Node;以下简称 RN) 的 HSPDA 网络中, 可以根据 UE的第一 H-RNTI和该 UE接入的 RN的第二 H-RNTI 之间的映射关系, 将发送给该 UE的数据通过该 RN准确地发送给该 UE。
本实施例的数据传输方法, 能够增加小区边缘的下行覆盖能力, 并进 一歩提高了向小区边缘的用户设备传输数据的效率。
图 1为本发明实施例提供的一种数据传输方法的流程图。 如图 1所示, 本实施例的数据传输方法可以如下所述。
100、 无线网络控制设备获取预存储的所述用户设备的所述第一 H-RNTI和所述用户设备接入的所述中继节点的所述第二 H-RNTI之间的映 射关系。
101、 所述无线网络控制设备根据所述映射关系, 向接入设备发送所述 第一 H-RNTI、 所述第二 H-RNTI和所述数据, 以供所述接入设备将所述数 据通过所述第二 H-RNTI对应的所述中继节点发送给所述第一 H-RNTI对应 的所述用户设备。
例如, RNC管理和维护 UE的第一 H-RNTI和该 UE接入的 RN的第二
H-RNTI之间的映射关系。 RNC获取 RNC中预存储的 UE的第一 H-RNTI 和该 UE接入的 RN的第二 H-RNTI之间的映射关系,然后根据该映射关系 通过 lub接口向接入设备(例如: Node B, 网关等,下面以接入设备为 Node B 为例) 发送第一 H-RNTI、 第二 H-RNTI 和数据, 例如发送包括第一 H-RNTK第二 H-RNTI和数据的 FP数据包。 例如, RNC向 Node B发送的 HSDPA FP数据包具体如表 1所示形式。
表 1
FP header H-RNTI DATA 如表 1所示, 该数据包的 FP帧头部携带有用于接收数据的 UE所接入 的 RN的第二 H-RNTI,而在数据 D ATA部分包括该 UE对应的第一 H-RNTI 和发送给该 UE的数据。 这样, 可以保证 Node B接收到该 FP数据包之后, 经过解析处理,获取 FP帧头部携带的第二 H-RNTI,然后将该第一 H-RNTI 和该数据准确地发送至与该第二 H-RNTI对应的 RN上。 Node B在向 RN 发送数据时, 在空中接口的 HS-SCCH上加上该 RN的第二 H-RNTI, 以便 对应的 RN检测到该第二 H-RNTI与其自身配置的第二 H-RNTI—致后,接 收 Node B发送给该 RN的该第一 H-RNTI和该数据。 该 RN接收到该第一 H-RNTI和该数据之后, 解析获取其中的第一 H-RNTI, 再将该数据发送至 与该第一 H-RNTI对应的 UE上, 并在空中接口的 HS-SCCH上加上该 UE 的第一 H-RNTI, 以便在该 UE—侧, 当该 UE检测到该第一 H-RNTI与其 自身配置的第一 H-RNTI—致后, 接收该 RN发送给该 UE的该数据。
本实施例的数据传输方法, 通过在 HSDPA网络中引入 RN, 并进一歩 地由 RNC根据预存储的 UE的第一 H-RNTI和该 UE接入的 RN的第二 H-RNTI之间的映射关系, 能够将发送给 UE的数据, 通过 Node B和 RN 准确地传输给该 RN覆盖下的该 UE。 通过采用本实施例的技术方案, 能够 扩大小区边缘的覆盖能力,并进一歩提高了向小区边缘的 UE传输数据的效 在本发明的另一实施例中, 例如, 在上述实施例中的向接入设备发送 所述第一 H-RNTI、 所述第二 H-RNTI和数据之前, 所述数据传输方法还可 以如下所述。
( 1 )所述无线网络控制设备根据所述中继节点发送的入网请求, 为所
例如, 在小区边缘引入 RN之后, RN通过 Node B向 RNC发送入网请 求, RNC接收到 RN的入网请求以后, 为该 RN分配一个第二 H-RNT, 并 通过 Iub接口通知 Node B, 并由 Node B通知给该 RN。
(2)所述无线网络控制设备根据接入所述中继节点的所述用户设备发 送的业务请求, 为所述用户设备分配所述第一 H-RNTI。
例如, 在小区边缘引入 RN之后, 该 RN之下便接入有位于此 RN服务 范围的 UE。 当该 UE接入该 RN之后, 向接入网发送 HSDPA业务请求, 当网络侧的 RNC接收到该 HSDPA业务请求,并准备为该 UE建立 HSDPA 业务时,为该 UE分配一个第一 H-RNTI,并通过 Iub接口将该第一 H-RNTI 通知给 Node B, 并由 Node B将该第一 H-RNTI通过该 RN通知给该 RN下 方的发起 HSDPA业务请求的该 UE。
(3 ) 所述无线网络控制设备建立所述用户设备的所述第一 H-RNTI和 所述用户设备接入的所述中继节点的所述第二 H-RNTI之间的所述映射关 系, 并存储。
例如, 在 RNC为入网的该 RN分配该第二 H-RNTI, 并为接入该 RN 的该 UE分配该第一 H-RNTI之后, RNC建立该 UE的第一 H-RNTI和该 UE接入的该 RN的第二 H-RNTI之间的映射关系并存储。 该映射关系将该 UE与该 UE接入的 RN进行绑定,当该 RN的第二 H-RNTI或者接入该 RN 的 UE第一 H-RNTI发生变化时, 该映射关系都需要修改更新。
本发明实施例通过在 HSPDA 网络的小区边缘引入中继节点 (Relay Node; 以下简称 RN:), 解决了现有 HSDPA技术中采用的 2msTTI的传输方 式, 降低了小区边缘的下行覆盖能力, 导致向小区边缘 UE传输数据延迟或 者误码以及不能送达等效率低下的问题。 本发明实施例通过在小区边缘引 入中继节之后, 能够实现由 Node B将发送给 RN覆盖下的 UE的数据通过 RN准确地发送给该 UE, 能够有效地提高向小区边缘的 UE传输数据的效 率。

例如, 在 HSDPA网络中, 在小区边缘加入 RN之后, RNC为接入该 RN的 UE以及该 RN分别分配第一 H-RNTI和第二 H-RNTI,并建立两者之 间的映射关系。 然后 RNC 根据该映射关系, 向接入设备 (例如, Node B 或网关, 但为描述方便, 下述以 NodeB为例进行说明) 发送第一 H-RNTI、 第二 H-RNTI和数据, 例如发送包括第一 H-RNTI、 第二 H-RNTI和数据的 FP数据包。 对应地, Node B接收 RNC发送的第一 H-RNTI、 第二 H-RNTI 和数据的 FP数据包。 该 FP数据包采用如上述表 1所示的形式, 在该 FP 数据包的 FP 帧头部携带有数据发送的目的地 UE所接入的 RN 的第二 H-RNTI, 而在 D ATA部分包括该 UE对应的第一 H-RNTI和发送至该 UE 的数据。
201、 所述接入设备根据所述第二 H-RNTI, 将所述第一 H-RNTI和所 述数据发送至所述第二 H-RNTI对应的所述中继节点,以供所述中继节点将 所述数据发送至所述第一 H-RNTI对应的所述用户设备。
例如, Node B根据接收到的 FP数据包中携带的 RN的第二 H-RNTI, 将表 1中的 DATA部分即包括第一 H-RNTI和发送至该 UE的数据发送给 第二 H-RNTI对应的 RN。 Node B在空中接口的 HS-SCCH上加上该 RN的 第二 H-RNTI, 以供该 RN检测到与其自身配置相同的第二 H-RNTI, 便接 收发送至接入该 RN的 UE的第一 H-RNTI和发送至该 UE的数据, 并对接 收到的第一 H-RNTI和数据进行解析处理, 获取其中的第一 H-RNTI。 RN 根据获取到的第一 H-RNTI,将该数据发送给该第一 H-RNTI对应的该 UE; RN在空中接口的 HS-SCCH上加上该 UE的第一 H-RNTI, 以便当该 UE检
测到该第一 H-RNTI与其自身配置的第一 H-RNTI—致后,接收该 RN发送 给该 UE的该数据。
本实施例的数据传输方法, 在 Node B下方接入 RN之后, HSDPA网 络中的 RNC根据 UE的第一 H-RNTI和该 UE接入的 RN的第二 H-RNTI 之间的映射关系, 将第一 H-RNTI、 第二 H-RNTI和发送给 UE的数据发送 给该 Node B, 该 Node B根据接收到的第二 H-RNTI, 能够将数据通过该第 二 H-RNTI对应的 RN准确地发送给第一 H-RNTI对应的 UE。 通过采用本 实施例的技术方案, 能够扩大小区边缘的覆盖能力, 并进一歩提高了向小 区边缘的 UE传输数据的效率。
