Description

利用寻呼信道传输业务数据的方法及系统、 用户设备 技术领域
本发明涉及 Always on业务传输技术，尤其涉及一种利用寻呼信道传输 业务数据的方法及系统， 用户设备。 背景技术
随着无线通信的不断发展， 业务的种类日趋多种多样， 业务不再仅仅 局限于传统的语音和短信业务， 一些新兴的业务也不断涌现， 如目前出现 了传输频繁但数据量较小的 Always on业务， 如 EMAIL、 专网连接等业务。 Always on业务的特点是可以在后台自动处理而无需用户干预， 但数据传输 需要始终保持持续。 对于这样的业务， 如果采用传统的接入方法， 即首先 对用户设备（UE, User Equipment )进行寻呼， 而后由 UE发起无线资源控 制 （RRC, Radio Resource Control )连接， 建立起专用无线信道， 在专用信 道（DCH, Dedicated Channel )状态下发送或接收用户数据， 那么 UE用户 就不能享受到高速数据传输速率的物理信道服务，如果 Always on业务也从 DCH 再转到高速下行链路共享信道（HS-DSCH , High-Speed Downlink Shared Channel )发送， 其发送流程又过于复杂， 因为这样一方面增加了额 外的信令开销， 另一方面交互过程又会增加业务建立的时延， 从而使得用 户体验降低。
因此， 第三代合作伙伴计划 ( 3GPP, 3rd Generation Partnership Project ) 在 Release8中引入了增强性前向接入信道（ FACH, Forward Access Channel ) 技术， 使 UE能在 CELL— FACH状态下以高数据速率接入和发送 Always on 业务数据的方法。 例如， 公开号为 CN101175302A、 公开日期为 2008年 5 月 7 日、 发明名称为 "永远在线类型业务保持方法和装置" 的中国专利申 请详细公开了如何实现增强性 FACH的方法，即利用 FACH实现 Always on 业务。 但是， Always on业务的实现并非仅限于利用 FACH实现， 如通过寻 呼信道（PCH, Paging Channel )等也能实现 Always on业务。
公开号为 CN101686527A、公开日期为 2010年 3月 31 日、发明名称为 "广播控制信道的发送及接收方法" 的中国专利申请详细公开了一种通过 PCH接收和发送 HS-DSCH传输资源的方法， 但其仅公开了基站与网络侧 间的交互过程， 重点对基站（NodeB )内部的信道配置过程进行了描述， 而 对 UE与基站， UE、 基站与网络侧间的信息交互并没有涉及。
可见， 对于如何在 CELL— PCH状态下实现 HS-DSCH信道的承载， 并 实现 Always on业务数据的传输， 当前还缺乏有效成熟的技术方案。 发明内容
有鉴于此， 本发明的主要目的在于提供一种利用寻呼信道传输业务数 据的方法及系统、 用户设备， 避免了 Always on业务应用面较窄。

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。
首先对下本发明中涉及的相关信道进行简单说明。
1 ) PCH是一个公共下行传输信道， 现有技术中 PCH承载于辅公共控 制物理信道 ( SCCPCH, Secondary Common Control Physical Channel )上； 本发明中， PCH承载于具有较高数据传输率的物理信道 HS-DSCH上， 当 UE在 PCH信道上发送或接收数据时称为处于 CELL— PCH状态；
2 ) HS-DSCH是一个下行物理信道， 因为在该信道上数据以较高的编 码率和高阶的调制方式进行传输 , 所以其具有很高的数据传输速率。
3 )广播控制信道（BCCH, Broadcast Control Channel )是逻辑信道， 其承载于 PCH上， 用于传输 "Always on" 业务的业务数据。
实施例一
本示例主要涉及 UE在 CELL— PCH状态下接收承载于 HS-DSCH上的 BCCH信道。
图 1 为本发明实施例一利用寻呼信道传输业务数据的方法的流程示意 图， 如图 1 所示， 本示例利用寻呼信道传输业务数据的方法具体包括以下 步驟：
步驟 101 :基站通过审计应答或资源状态指示将小区能力告知网络控制 器；
具体的， 基站发送的资源审计应答或资源状态指示中必须含有的小区 能力包括有 "Enhanced FACH Capability"、 "Enhanced PCH Capability"； 上 述能力指示了基站具有传输高速数据速率的 PCH信道的能力。
步驟 102:网络控制器通过物理共享资源重配置请求将公共 mac-d以及 公共无线网络临时标识（RNTI, Radio Network Temporary Identifier ) 配置 给基站；
所述物理资源重配置请求是一条网络控制器发送至基站的命令， 该命 令中网络控制器将 HS-DSCH 信道的一系列参数 （ HS-DSCH Common System Information LCR )配置给基站；上述参数中至少含有用于指示 BCCH 载的无线网络临时标识 "BCCH Specific HS-DSCH RNTI Information LCR" 和寻呼系统信息（ HS-DSCH Paging System Information LCR )。
步驟 103: UE读取系统消息，并向小区的基站发起 RRC连接建立请求； 所述的系统信息， 在其第 5个系统信息块（SIB5 ) 中包含有步驟 2中 网络控制器给基站所配置的一系列信息， 至少包含有 "HS-DSCH common system information" 和 "HS-DSCH paging system information"。 "HS-DSCH common system information" 中包含 "HS-SCCH system info"、 "Common H-RNTI Information"、 "BCCH specific H-RNTI" 等参数；
在 UE发送的 RRC连接建立请求消息中含有指示 UE具有传输承载于 高速物理信道上的 PCH信道能力的参数 "HS-PDSCH in CELL FACH" 0 即 UE具有能接收承载于 HS-DSCH上的 PCH的能力。
步驟 104: 基站将 RRC 连接建立请求消息通过帧协议 ( FP, Frame Protocol ) 帧发送给网络控制器；
FP是基站与网络控制器间交换用户面信息的帧协议， 并且该 FP帧携 带有基站将要分配给 UE的 E-DCH无线网络临时标识（E-RNTI, E-DCH Radio Network Temporary Identifier )。
步驟 105: 网络控制器接收到连接建立请求消息后为 UE 分配相应的 HS-DSCH无线网络临时标识（ H-RNTI, HS-DSCH Radio Network Transaction Identifier ), 并通过 FP帧向基站发送确认 RRC连接建立的消息； 该 FP帧 携带有分配给 UE的 H-RNTI和 E-RNTI;
基站接收到 FP帧后，将分配给 UE的 H-RNTI和 E-RNTI以及 RRC连 接建立消息转发给 UE;
UE接收到 RRC连接建立消息后进入 CELL-PCH状态。
步驟 106: 基站通过寻呼指示信道（ PICH, Paging Indicator Channel ) 发送寻呼指示， 指示 UE接收寻呼。
步驟 107: UE在 N个时间间隔内接收高速共享控制信道（HS-SCCH,
High Speed Shared Control Channel )接收并完成同步过程；
所述时间间隔是由网络事先配置的， 该时间间隔是 UE接入 HS-SCCH 信道所必要的时间。
步驟 108: 基站触发小区系统信息更新， 使用 BCCH specific H-RNTI 发送 HS-SCCH信道信号；
具体的， 基站所发送的更新消息 "HS-SCCH system info" 中所列出的 第一个 HS-SCCH信道上利用 "BCCH specific H-RNTI" 指示 UE接收 HS-DSCH上的 BCCH;
UE接收到更新消息后保持在 HS-SCCH上的数据接收， 并准备接收系 统消息更新；
此后， 基站可以在 HS-DSCH 上发送 RRC 消息 " SYSTEM INFORMATION CHANGE INDICATION"； 同时 UE在 HS-DSCH上接收系 统消息更新。
实施例二
本示例主要涉及 UE在 URA— PCH状态下接收 HS-DSCH上的物理控制 信道（PCCH, Physical Control Channel ), 获知对 BCCH进行修改的通知。
图 2 为本发明实施例二利用寻呼信道传输业务数据的方法的流程示意 图， 如图 2所示， 本示例利用寻呼信道传输业务数据的方法具体包括以下 步驟：
步驟 201 :基站通过审计应答或资源状态指示将小区能力告知网络控制 器；
具体的， 基站发送的资源审计应答或资源状态指示中必须含有的小区 能力包括有 "Enhanced FACH Capability"、 "Enhanced PCH Capability" ; 上 述能力指示了基站具有传输高速数据速率的 PCH信道的能力。
步驟 202:网络控制器通过物理共享资源重配置请求将公共 mac-d以及 公共无线网络临时标识（RNTI, Radio Network Temporary Identifier ) 配置 给基站；
所述物理资源重配置请求是一条网络控制器发送至基站的命令 , 该命 令中网络控制器将 HS-DSCH 信道的一系列参数 （ HS-DSCH Common System Information LCR )配置给基站；上述参数中至少含有用于指示 BCCH 载的无线网络临时标识 "BCCH Specific HS-DSCH RNTI Information LCR" 和寻呼系统信息（ HS-DSCH Paging System Information LCR )。
步驟 203: UE读取系统消息，并向小区的基站发起 RRC连接建立请求； 所述的系统信息， 在其第 5个系统信息块（SIB5 ) 中包含有步驟 2中 网络控制器给基站所配置的一系列信息， 至少包含有 "HS-DSCH common system information" 和 "HS-DSCH paging system information"。 "HS-DSCH common system information" 中包含 "HS-SCCH system info"、 "Common H-RNTI Information"、 "BCCH specific H-RNTI" 等参数；
在 UE发送的 RRC连接建立请求消息中含有指示 UE具有传输承载于 高速物理信道上的 PCH信道能力的参数 "HS-PDSCH in CELL— FACH" 即 UE具有能接收承载于 HS-DSCH上的 PCH的能力。
步驟 203过后， UE进入 URA PCH状态，此时， UE没有专用 H-RNTI。 UE在 CELL— PCH状态与 URA— PCH状态的区别是， 没有专用 H-RNTI, 后 续步驟中不需要建立 HS-SCCH信道， 而是直接在高速物理下行共享信道 ( HS-PDSCH, High Speed-Physical Downlink Shared Channel )上传输 PCH。 步驟 204: 基站使用相应标识指示某个或某几个系统信息块（SIB , System Information Block ) 更新， 触发向 UE发送 PICH指示 UE接收相关 联的寻呼子帧；
步驟 205: UE在接收到 PICH后的 N个间隔周期内开始在 HS-DSCH 上接收与 PICH相关联的寻呼子帧；
也就是说， UE检测到 PICH上的寻呼指示， 指示 PCCH传输， 然后 UE接收与 PICH相关联的 HS-PDSCH子帧。
步驟 206: UE接收到 PCCH并判断系统消息需要更新；
具体的， UE接收到相应 HS-DSCH上的 PCCH, PCCH上 载的 RRC 消息为 "PAGING TYPE 1，，， 消息中携带 "BCCH modification info" , 其中 的 "MIB value tag" 发生了改变；
然后， UE开始接收系统消息并能接收到更新的系统信息块。

所述物理资源重配置请求是一条网络控制器发送至基站的命令， 该命 令中网络控制器将 HS-DSCH 信道的一系列参数 （ HS-DSCH Common System Information LCR )配置给基站；上述参数中至少含有用于指示 BCCH 载的无线网络临时标识 "BCCH Specific HS-DSCH RNTI Information LCR" 和寻呼系统信息（ HS-DSCH Paging System Information LCR )。
步驟 303: UE读取系统消息，并向小区的基站发起 RRC连接建立请求； 所述的系统信息， 在其第 5个系统信息块（SIB5 ) 中包含有步驟 2中 网络控制器给基站所配置的一系列信息， 至少包含有 "HS-DSCH common system information" 和 "HS-DSCH paging system information"。 "HS-DSCH common system information" 中包含 "HS-SCCH system info"、 "Common H-RNTI Information"、 "BCCH specific H-RNTI" 等参数；

步驟 305: 网络控制器接收到连接建立请求消息后为 UE 分配相应的 H-RNTI, 并将确认 RRC连接建立的消息通过 FP帧反馈给基站； 该 FP帧 携带有分配给 UE的 H-RNTI和 E-RNTI;
基站将分配给 UE的 H-RNTI和 E-RNTI以及 RRC连接建立消息发送 给 UE;
UE接收到 RRC连接建立消息后进入 CELL PCH状态。
步驟 306:基站在 PICH上向处于 CELL— PCH状态下的 UE发送寻呼指 示； 触发向 UE发送下行专用信令或数据， 基站通过 HS-SCCH通知 UE接 收专用信令与数据；
基站在与 PICH帧相关联的第一个 HS-SCCH子帧发送 HS-SCCH order, 通过 UE专有 H-RNTI标识 UE; UE检测到该同步 HS-SCCH, 使用专用 E-RNTI 向基站发起 E-DCH 随机接入上行控制信道（E-RUCCH, E-DCH Random Access Uplink Control Channel ),基站检测到上行同步后，在相应的 HS-DSCH子帧发送 HS-DSCH传输块。
步驟 307: UE接收到 HS-SCCH后在对应的 HS-DSCH上接收专用信令 与数据。
