Description

一种实现信息传输的方法、 装置及系统 本申请要求了 2007 年 10 月 31 日提交的申请号为 200710124236.6、 发明名称为一种实现信息传输的方法、 装置及系统 的申请的优先权, 其全部内容通过引用结合在本申请中。 技术领域
本发明实施例涉及无线通信技术领域,具体是涉及一种实现信息 传输的方法、 装置及系统。 背景技术
无线通信系统中, 包括用户设备 ( UE , User Equipment )、 UMTS ( Universal Mobile Telecommunications System, 通用移动通讯系统 ) 基站(NodeB )之类的基站及 RNC之类的无线网络控制设备。 且 UE 与 NodeB之间、 NodeB与 RNC ( Radio Network Controller, 无线网 络控制器 )之间的信道均为 RACH(Random Access Channel,随机接入 信道)信道。
为增强 UE与 NodeB间的数据传输速率,目前业界已提出了在下 行公共信道中使用 HSDPA ( High Speed Downlink Packet Access, 高速下行分组接入技术)的处理方案, 从而在理论上能够使得下行传 输速率达到 100Kbps。 但下行传输速率还要受到上行传输速率的影 响。 比如, 目前的上行传输主要是釆用共享 RACH信道的方式, 这 种方式导致上行响应较慢, 进而会影响下行传输速率。
为解决该问题, 目前业界针对上行传输提出了釆用 HSUPA ( High Speed Uplink Packet Access, 高速上行分组接入技术)与随 机接入的传输方案。 该方案要求 UE在进行上行的随机接入传输时, 使用 E-DCH ( Enhanced Dedicated Channel, 增强专用信道)传输承载 信道来进行具体消息的传输, 也就是说, UE 与 NodeB 之间使用 E-DCH信道。 该方案能够使 UE与 NodeB之间的信息交互速度大大 增力口。
在实现本发明的过程中, 发明人发现现有技术至少存在以下问 题:
为进一步增大 UE上行发送的数据在 RNC与 NodeB之间的传输 速率, 可以在 RNC与 NodeB之间也使用 E-DCH传输承载信道。 由 于 UE数据量少, 并且是间断性的, 如果在 RNC与 NodeB之间使用 专用的 E-DCH信道, 则会极大地浪费资源。
而 RNC与 NodeB之间的信道^ ^于端口的,与 UE和 NodeB之 间基于空口的信道情况不同,无法将 UE与 NodeB间分配随机接入的 E-DCH传输承载信道的方案转用到 RNC与 NodeB的信道分配上。
发明内容
本发明实施例提供一种实现信息传输的方法,以实现在加快 RNC 与 NodeB间的信息传输的同时, 尽量节约 RNC与 NodeB之间的信 道资源。 本发明实施例还提供了一种实现信息传输的装置及系统。
为解决上述问题, 本发明各主要实施方式主要如下:

基站根据所述消息中的参数建立 E-DCH共享传输信道, 并通过 所建立的 E-DCH共享传输承载与无线网络控制设备交互信息。

所述系统中的无线网络控制设备用于向基站发送 E-DCH共享传 输信道的建立 /重配置消息;
所述系统中的基站用于根据无线网络控制设备发送来的建立 /重 配置消息建立 E-DCH共享传输信道,以及通过所建立的 E-DCH共享 传输承载与无线网络控制设备交互信息。 本发明实施例的一种实现信息传输的基站,
基站用于接收无线网络控制设备发送来的 E-DCH共享传输信道 的建立 /重配置消息; 根据所述消息中的参数建立 E-DCH共享传输信 道, 以及通过所建立的 E-DCH共享传输承载与无线网络控制设备交 互信息。
与现有技术相比, 本发明实施例通过 NodeB 之类的基站接收 RNC之类的无线网络控制设备发送来的 E-DCH共享传输信道的建立 /重配置消息, 并基于该消息建立 E-DCH共享传输信道, 之后通过所 建立的 E-DCH共享传输承载与无线网络控制设备交互信息, 从而使 得基站与无线网络控制设备之间能够以共享方式使用 E-DCH传输承 载, 实现了在加快 RNC与 NodeB间的信息传输的同时, 节约了基站 与无线网络控制设备之间的信道资源。 附图说明

图 2为本发明系统实施例的结构示意图。
图 3为本发明系统实施例的基站结构示意图。 具体实施方式
为使本发明的目的、技术方案和优点更加清楚, 下面将结合附图 对本发明作进一步地详细描述。 另外, 为方便描述, 本发明实施例中 的基站以 NodeB为例, 无线网络控制设备以 RNC为例。 显然, 其他 类似设备也可以实现本发明方案。
本发明实施例在 RNC与 NodeB之间配置 E-DCH共享传输信道 的实现流程如图 1所示, 对应以下步骤:
步骤 101、 RNC向 NodeB发送 E-DCH共享传输信道的建立 /重 配置消息, 以请求 NodeB建立一个 E-DCH传输信道。 RNC向 NodeB发送的建立 /重配置消息, 具体可以是建立 /重配 置请求, 本发明实施例具体以建立 /重配置请求为例。
RNC需要通过发送给 NodeB的请求告知信道建立 /重配置所需的 相关参数。 具体来说, 该参数可以包括 UE使用 E-DCH进行随机接 入所使用的签名列表和 /或相关的物理层信道参数,还可以是包括 UE 使用 E-DCH进行随机接入所需的相关物理层参数、 传输信道参数及 传输承载参数中的一个或多个, 当然, 还可以进一步包括前两种中的 一个或全部。 所发送的参数可以单独用新的消息发送; 也可以将这些 参数添加到现有过程的消息中, 即使用原有过程来发送这些参数。
如果 RNC将 UE使用 E-DCH进行随机接入所使用的签名列表发 送给 NodeB, RNC可以有多种发送方式。 本实施例提供了几种方式: 一种是在协议中规定一个表格, 然后给出表格的编号, 并发送该表格 编号; 另一种是给出签名序列, 并发送该签名序列; 还可以是使用与 传统物理随机接入信道( PRACH, Physical Random Access Channel ) 中的前同步码签名 (Preamble Signatures )类似的方式发送。 对于这 些发送方式来说, 具体可以在公共传输信道建立过程中执行。
如果 RNC将 UE使用 E-DCH进行随机接入所需的相关物理层信 道参数发送给 NodeB, RNC 同样有多种发送方式。 本实施例提供了 RNC告知 NodeB利用捕获指示信道( AICH )、 物理下行共享信道相 关共享控制信道 ( HS-SCCH , HS-DSCH-related Shared Control Channel )、 高速物理下行共享信道( HS-PDSCH, High Speed Physical Downlink Shared Channel )等信道的配置来完成相关资源指派的具体 处理方式, 具体有如下几种方式:
一种是在发送给 NodeB的 AICH中增加一个格式指示 ( AI )指 示, 以表示该 AICH可以在使用 E-DCH进行随机接入时使用, 对于 这种方式来说, 也可以在公共传输信道建立过程中对 AICH进行修 改。
另一种是针对物理下行共享信道相关共享控制信道 ( HS-SCCH ) 的方式,对于这种方式来说, 可以在发送给 NodeB的 HS-SCCH中增 加物理层参数、 HS-SCCH格式编号及 HS-SCCH的时序关系中的至 少一个。 对于这种方式来说, 也可以在物理共享信道重配过程中对 HS-SCCH进行修改。 另外, 该物理层参数可以为信道化码和功率, 功率可以是最大发射功率和 /或初始发射功率;对于 HS-SCCH格式编 号来说, 由于目前的 HS-SCCH有 3种格式, 因此需要指示具体是使 用哪种格式; HS-SCCH的时序关系, 则可以是 HS-SCCH与某个绝 对时序的参照, 比如, 可以是与 AICH 或主公共控制物理信道 ( P-CCPCH, Primary Common Control Physical Channel )的偏移, 单 位可以是时隙或 256chip。
还有一种是针对高速物理下行共享信道(HS-PDSCH )方式, 对 于这种方式来说, 可以在发送给 NodeB的 HS-PDSCH中增加物理层 参数、 HS-PDSCH的时序关系、传输信道参数中的至少一个。 对于这 种方式来说, 也可以在公共传输信道建立过程中对 HS-PDSCH进行 修改。 另外, 该物理层参数可以包括信道化码、 调制方式、 功率、 TB size中的至少一个; HS-PDSCH的时序关系可以是 HS-PDSCH与某 个绝对时序的参照, 比如可以是与 AICH或 P-CCPCH的偏移, 单位 可以是时隙或 256chip; 传输信道参数则包括 MAC的格式指示, 具 体可以包括 MAC-hs、 DPA增强中的 MAC-ehs, 或者定义新的格式。
如果 RNC 将 UE使用 E-DCH进行随机接入所需使用的相关 E-DCH 物理层参数、 传输信道的参数、 传输承载的参数等发送给 NodeB, RNC同样有多种发送方式。
E-DCH物理层参数可以包括下表中的参数, 且这些参数可以是 在公共传输信道建立过程中增加。
Figure imgf000008_0001
传输信道的参数则可以包括下表中的参数,具体可以是在物理共 享信道重配置中增加一个指示, 以表明该参数可以在使用 E-DCH进 行随机接入时使用 ,还可以直接将该参数增加到公共传输信道建立过 程中。

步骤 102、 NodeB根据所收消息中的参数建立 E-DCH共享传输 信道, 并通过所建立的 E-DCH共享传输承载与 RNC进行信息交互。
NodeB还可以向 RNC反馈信道建立 /重配置的响应,告知所建立 的 E-DCH传输信道的信息。
NodeB针对 RNC发送来的参数, 建立相应的 E-DCH共享传输 信道, 并将所建立信道的相关信息反馈给 RNC。 具体来说, 将传输 层地址和 /或绑定标识(Binding ID )告知 RNC即可, 当然, 还可以 将该 E-DCH传输承载信道的其他相关参数告知 RNC。
并且,在建立 E-DCH共享传输信道后,如果 NodeB需要向 RNC 发送 UE的相关信息, 则需要将 UE ID告知 RNC。 具体来说, NodeB 在收到 UE发送来的信息后,同样需要该 NodeB在收到的信息中添加 UE ID, 所不同的是, 该修改的目的是将该数据修改为新的 E-DCH 数据, 或者是将该数据所对应的 E-DCH FP帧修改为包含 UE ID的 FP帧。
爹改后的 FP帧具体如下表所示。 Header crc FT

Payload CRC Payload CRC cont 对于上述使用 E-DCH共享传输承载将数据传输给 RNC的处理方 案来说, 还需要修改 RNC的处理逻辑, 以使得 RNC能够解析出 UE ID。 具体来说, 可以是对 MAC-es实体做相应的修改。 当然, 该修改 是基于 RNC中解析出 UE ID的实体为 MAC-es实体的, 如果是基于 其他实体, 则需要对该实体做相应的修改。
由上述实施例可以看出,本发明实施例进使得 RNC与 NodeB之 间也能够通过 E-DCH进行随机接入, 节约了 RNC与 NodeB之间的 信道资源。
本发明系统实施例中,如图 2所示,包括 RNC 210和 NodeB 220, 其中,
RNC 210需要向 NodeB 220发送 E-DCH共享传输信道的建立 / 重配置消息;
NodeB 220则需要根据该请求中的参数建立 E-DCH共享传输信 道, 并通过所建立的 E-DCH共享传输承载与无线网络控制设备交互 信息。
NodeB 220还可以用于, 将所建立的 E-DCH共享传输信道的信 息反馈给 RNC 210。
之后, NodeB 220与 RNC 210之间即可通过所建立的 E-DCH共 享传输承载进行信息传输。
对于 RNC 210发送建立 /重配置请求来说, RNC 210可以在建立 / 重配置请求中发送 UE使用 E-DCH进行随机接入所使用的签名列表、 UE使用 E-DCH进行随机接入所需的相关物理层信道参数、 UE使用 E-DCH进行随机接入所需的相关物理层参数、 传输信道参数及传输 承载参数的任意一个或任意组合。
RNC 210发送建立 /重配置请求, 以及 NodeB 220反馈所建立的 E-DCH共享传输信道的信息, 前面已有详细描述, 这里不再赘述。
在建立 E-DCH共享传输承载信道后, 如果 NodeB 220需要向 RNC 210发送 UE的相关信息, 则需要将 UE ID告知 RNC 210。具体 来说, NodeB 220在收到 UE发送来的信息后,同样需要该 NodeB 220 在收到的信息中添加 UE ID, 以将该数据修改为新的 E-DCH数据, 或者是将该数据所对应的 E-DCH FP帧修改为包含 UE ID的 FP帧。
相应地, RNC 210则需要解析出所收信息中的 UE ID。 比如, 针 对新的 E-DCH数据和 E-DCH FP帧 , 对 RNC 210中的 MAC-es实体 进行修改。 具体实现前面已有详细描述, 这里不再赘述。
由前面的方法及系统实施例可以看出, 本发明的装置实施例中, NodeB 220 需要根据 RNC 210 发送来的所述消息中的参数建立 E-DCH共享传输信道,还可以进一步用于向 RNC 210反馈信道建立 / 重配置的响应, 告知所建立的 E-DCH共享传输信道的信息。
相应地, RNC 210则需要向 NodeB 220发送 E-DCH共享传输信 道的建立 /重配置请求。
在 NodeB 220与 RNC 210之间建立 E-DCH共享传输信道后, NodeB 220还可以进一步用于, 将 UE通过 E-DCH共享传输信道传 输来的信息增加 UE标识, 将该信息中的数据转换成携带 UE标识的 E-DCH数据, 或者将该信息转换成携带 UE标识的 FP帧, 以及将修 改后的信息通过 E-DCH共享传输承载发送给 RNC 210。
上述实现信息传输的基站 220, 具体可以包括:
收发模块 221 , 用于接收无线网络控制设备 RNC 210发送来的 E-DCH共享传输信道的建立 /重配置消息;
信道建立模块 222, 用于根据消息中的参数建立 E-DCH共享传 输信道, 以及控制收发模块 221通过所建立的 E-DCH共享传输承载 与无线网络控制设备 210交互信息。
该基站还可以进一步包括,
标识模块 223 , 用于在收到 UE发送来的信息后, 在该信息中增 加该 UE的标识信息, 将该信息中的数据修改为新的 E-DCH数据, 或者将该数据所对应的 E-DCH FP帧修改为包含 UE标识信息的 FP 帧。以及控制所述收发模块 221将修改后的信息通过所建立的 E-DCH 共享传输承载发送给无线网络控制设备 210。
由上述实施例可以看出, 本发明实施例进一步使得 RNC 与 NodeB之间也能够通过 E-DCH进行随机接入,节约了 RNC与 NodeB 之间的信道资源。
