步骤 101 , 宏基站与用户设备 UE建立无线资源控制 RRC连接; 步骤 102 ,所述小节点接收所述宏基站通过有线或无线接口发送的配置 消息;
步骤 103 , 所述小节点按照所述配置消息建立所述小节点与所述 UE之 间的用户面连接,并与所述 UE在所述用户面连接上建立数据承载。
本发明实施例的执行主体为小节点, 小节点可以为: 小基站(P i co ), 室内基站(Femto ), 低移动性基站(Low Mob i l i ty, LoMo ), 其他本地无线 接入点 AP, 或者带有设备到设备 ( D2D )功能的 UE。 本实施例以小节点为 LoMo为例。
宏基站主要用于实现该 UE的控制面功能, 包括该 UE的移动性管理功 能。 LoMo主要用于承载室内低移动性数据业务, 实现用户面功能。 具体而 言, 该空中接口的用户面数据传送和控制面数据传送采用不同路径的分离 传送方式, 即, LoMo到 UE的链路只负责用户面数据的传输, LoMo到 UE的 控制面信令由宏基站到 UE的链路进行建立。
如图 2所示,宏基站与 UE通过空中接口直接连接,无需经过 LoMo , LoMo 通过宏基站与 UE之间的这一接口建立 RRC连接。 宏基站与 LoMo通过有线 或者无线接口相连, 其中有线接口可以包括: 基站和移动性管理实体 E 之间的 S1接口, 和 /或基站与基站之间的 X2接口, 和 /或通用公共无线接 口 CPRI , 和 /或无线网络控制器与基站之间的 lub接口, LoMo通过这一接 口接收所述宏基站通过有线或无线接口发送的配置消息; 其中无线接口包 括: 基站与 UE之间的 Uu接口, 和 /或基站传输的微波接口。 LoMo与 UE之 间的数据承载由上述宏基站与 UE的接口进行配置。
LoMo通过所述数据承载接收所述 UE的用户面数据之后, 可以通过图 1 中的宏基站与 LoMo之间的有线或者无线接口发送给宏基站, 以使所述宏基 站将所述 UE的用户面数据转发给核心网网元; 或者, 还可以通过图 3中的 核心网网元与 LoMo之间的接口将所述 UE的用户面数据直接发送给核心网 网元, 图 3中的核心网网元为月良务网关 S-GW。
若 LoMo直接和核心网网元进行数据传输, 则 LoMo需要将自身的地址 告知移动管理实体匪 E , MME告知核心网网元, MME再将核心网网元的地址 告知宏基站, 由宏基站转发给 LoMo。 上述地址可以包括: 传输网络层地址 TNL addres s , 通用无线分组业务隧道协议-隧道节点标识 GTP-TEI D和 /或 互联网协议 IP地址。
LoMo 与 UE 之间的空中接口协议栈可以仅包括: 分组数据汇聚协议
PDCP , 无线链接控制 RLC层协议, 媒体访问控制 MAC层协议, 和层一 L1协 议; 和 /或不包括: 无线资源控制 RRC层协议。 即控制面上, LoMo和 UE的 空口协议栈可以采用筒化的协议栈架构, 例如没有 RRC协议实体。 如图 4 所示。 用户面上, LoMo和 UE可以采用原来的用户面协议栈 PDCP/RLC/MAC , 只是从功能上裁剪。 如图 5所示。
LoMo与 UE之间的控制面协议栈还可以将 PDCP、 RLC , MAC合并为一新 层实体,如图 6所示。 LoMo与 UE之间的用户面协议栈还可以将 PDCP、 RLC , MAC合并为一新层实体, 如图 7所示。
当小节点为带有 D2D功能的 UE时, 在步骤 1 01之前还可以包括以下步 骤: 步骤 1 04 , 当小节点在 UE附近时, UE向宏基站发起 RRC连接以建立业 务。 宏基站判断所述小节点存储有 UE请求的数据。 即当宏基站确定 UE请 求的数据, 在附近的小节点就有时, 直接让该小节点传输给 UE。
上述配置消息还可以包括: 静态或半静态配置资源的分配信息; 在所 述静态或半静态配置资源上进行随机接入的资源分配信息, 或进行随机接 入和数据调度的资源分配信息。 如果所述配置消息仅包括所述进行随机接 入的资源分配信息, 则所述小节点与所述 UE在所述用户面连接上建立数据 承载之后进一步包括: 所述小节点通过建立的数据承载, 向所述 UE发送在 所述静态或半静态配置资源上进行随机接入的资源分配信息。 如果所述配 置消息包括所述随机接入和数据调度的资源分配的静态半静态信息, 所述 小节点与所述 UE在所述用户面连接上建立数据承载之后进一步包括: 所述 小节点通过建立的数据承载向所述 UE发送在所述静态或半静态配置资源上 配置资源上进行随机接入和数据调度的资源分配信息。 如果按照所述资源 分配信息进行随机接入, 或随机接入和数据调度时发生拥塞, 则进一步包 括: 所述小节点向宏基站重新申请静态或半静态的配置资源; 或者所述小 节点通知所述宏基站将所述 UE切换到所述宏基站下; 或者所述小节点将资 源发生拥塞的新接入采用动态调度方式。
下表为宏基站与 LoMo的功能比较, 其中 LoMo—列列出了 LoMo可以筒 化的功能:

与现有技术相比, 在本发明实施例所提供的方法中, 小节点可以通过 宏基站建立与用户设备 UE的无线资源控制 RRC连接, 再由宏基站对小节点 进行配置, 从而节省了与 UE建立 RRC连接的流程, 降低了成本; 然后小节 点与 UE建立数据承载, 分担了宏基站的数据流量, 从而提高移动宽带通信 的带宽、 容量。 图 8 为本发明实施例一种无线宽带通信的方法的信令交互图, 本实施 例包括:
步骤 801 : UE不直接接入 LoMo, UE发起业务时首先同宏基站建立 RRC 连接, 进行正常的鉴权加密。
步骤 802: 宏基站对所述 UE进行 RRC重配以建立相应的第二信令无线 承载 SRB2, 数据无线承载 DRB, 测量控制配置等等, UE收到 RRC重配消息 (RRC reconf igurat ion)后进行底层配置, 包括无线资源配置, 测量配置等 等。
步骤 803: 宏基站在发送 RRC重配消息(RRC reconf igurat ion)的同时, 需要通过一个新定义的接口 (s imple IF ) 完成对 LoMo 的底层用户面协议 栈(包括 PDCP, RLC, MAC )或者新定义的用户面实体(new MAC )进行配置。 该接口 (s imple IF)传递的配置消息包括:
无线资源配置 (逻辑信道配置, 传输信道配置, 物理信道配置) 测量配置等等。
特别地, 由于室内覆盖场景下, UE数比较少, 无线资源配置可以是静 态或者半静态的 RACH 资源和 /或静态或半静态的物理传输资源。 静态或半 静态资源信息根据 AP下的常住户的资源使用情况设定
此处步骤 802和 803可以同时进行, 或依次进行。
步骤 804 : UE和 LoMo分别向宏基站反馈配置响应消息。
根据该接口(s impe I F)传递的信息不同, 有以下三种选择:
选择 1 : 只包括静态或者半静态的 RACH资源,后续调度的信息再由 LoMo 通过 MAC CE ( MAC层控制单元)进行通知。
选择 2: 配置消息包括 UE随机接入和后续调度的静态或半静态资源信 息, 如果资源分配发生拥塞, 则 LoMo向宏基站重新申请半静态的资源分配 或者把 UE切换到宏基站下。
选择 3: 配置消息包括 UE随机接入和后续调度的静态半静态资源信息, 如果 UE在后续接入过程中发生资源拥塞, 资源发生拥塞后的接入采用动态 调度方式。
步骤 805 : UE和 LoMo建立用户面 7 载。

与现有技术相比, 在本发明实施例所提供的方法中, 小节点可以通过 宏基站建立与用户设备 UE的无线资源控制 RRC连接, 再由宏基站对小节点 进行配置, 从而节省了与 UE建立 RRC连接的流程, 降低了成本; 然后小节 点与 UE建立数据承载, 分担了宏基站的数据流量, 从而提高移动宽带通信 的带宽、 容量。 图 9 为本发明实施例一种无线宽带通信的方法的信令交互图, 本实施 例包括: 步骤 901 , UE首先同宏基站建立 RRC连接;
步骤 902 : 宏基站根据业务的服务质量(QoS )、 调度策略、 和 /或信道 质量等判断是否需要配置一个辅载波(SCC );
步骤 903 : 宏基站通过专用信令配置给 UE进行 SCC相关的配置; 步骤 904 : 宏基站通过新定义的接口消息配置 LoMo , LoMo接收到宏基 站的 SCC配置消息。
步骤 905 : 通过 LoMo的 MAC CE向 UE发送激活消息。
步骤 906 : UE收到激活消息之后, 进行 LoMo的随机接入, 获得新的第 二小区无线网络临时标识(C-RNT I 2 )。

本实施例中 PCC和 SCC的关联关系永远不变, 也就是说 UE和宏基站的 链路永远是 PCC , UE和 LoMo的链路永远是 SCC。
与现有技术相比, 在本发明实施例所提供的方法中, 小节点可以通过 宏基站建立与用户设备 UE的无线资源控制 RRC连接, 再由宏基站对小节点 进行配置, 从而节省了与 UE建立 RRC连接的流程, 降低了成本; 然后小节 点与 UE建立数据承载, 分担了宏基站的数据流量, 从而提高移动宽带通信 的带宽、 容量。 图 1 0为本发明实施例另一种无线宽带通信的方法的流程图, 本实施例 包括:

本发明实施例的执行主体为小节点, 小节点可以为: 小基站(Pico ), 室内基站 ( Femto ) , 或其他本地无线接入点 AP, 低移动性基站 (Low Mobi l i ty, LoMo )。 本实施例以小节点为 LoMo为例。
本发明实施例中的 LoMo可以处于宏基站的盲区中。 UE可以单独驻留在 LoMo上。
如图 11所示, 宏基站与 LoMo通过有线或者无线接口相连, 其中有线 接口可以包括: 基站和移动性管理实体匪 E之间的 S1接口, 和 /或基站与 基站之间的 X2接口, 和 /或通用公共无线接口 CPRI , 和 /或无线网络控制器 与基站之间的 lub接口, LoMo通过这一接口接收所述宏基站通过有线或无 线接口发送的配置消息; 其中无线接口包括: 基站与 UE之间的 Uu接口, 和 /或基站传输的微波接口。 LoMo与 UE之间也通过空中接口连接, 且无需 通过宏基站, 这一接口承载了 UE与 LoMo之间的信令和数据承载。
LoMo通过所述数据承载接收所述 UE 的用户面数据之后, 可以通过图
11中的宏基站与 LoMo之间的有线或者无线接口发送给宏基站,以使所述宏 基站将所述 UE 的用户面数据转发给核心网网元; 或者, 还可以通过图 12 中的核心网网元与 LoMo之间的接口将所述 UE的用户面数据直接发送给核 心网网元, 图 12中的核心网网元为服务网关 S-GW。
若 LoMo直接和核心网网元进行数据传输, 则 LoMo需要将自身的地址 告知移动管理实体匪 E, MME告知核心网网元, MME再将核心网网元的地址 告知宏基站, 由宏基站转发给 LoMo。 上述地址可以包括: TNL 地址, GTP-TE I D , 和 /或互联网协议 IP地址。
LoMo与 UE之间的空中接口协议栈可以仅包括: 控制面上, LoMo和 UE 的空口协议栈可以采用筒化的协议栈架构, 例如筒化 RRC协议实体, 如图 1 3所示。 功能上采用如图 1 0所述的筒化 RRC过程。 用户面上, LoMo和 UE 可以采用原来的用户面协议栈 PDCP/RLC/MAC , 只是从功能上裁剪。 协议栈 如图 14所示, 功能筒化部分如表一所示。
LoMo与 UE之间的控制面协议栈还可以将 PDCP、 RLC、 MAC合并为一新 层实体,如图 15所示。 LoMo与 UE之间的用户面协议栈还可以将 PDCP、 RLC、 MAC合并为一新层实体, 如图 16所示。
上述网络配置包括以下至少一项: 逻辑信道配置; 信令无线承载 SRB 配置; MAC层配置; 半静态调度配置; 物理信道配置; RRC消息的定时器参 数。
若需要执行小节点和小节点间的, 或小节点向宏基站方向的切换, 或 宏基站向小节点方向的切换, 上述通知所述 UE通过所述小节点接入网络之 后还包括:
步骤 1 004 , 所述小节点接收宏基站发送的测量控制信息, 并转发至所 述 UE;
步骤 1 005 , 所接收所述 UE反馈的测量报告, 并转发至所述宏基站; 步骤 1 006 , 所若所述宏基站判决需要进行切换, 则接收所述宏基站发 送的切换通 口。
本发明实施例所提供的方法, 小节点通过判断 UE发送的 Preamb l e或 者显示指示, 获知 UE是否需要重新建立或修改 SRB 1和 /或 SRB2 , 如果判 断为不需要, 则直接回复无需重新建立或者修改 SRB 1和 /或 SRB2 , 并通知 UE接入网络, 从而节省了建立 SRB 1和 /或 SRB2的流程, 降低了成本, 然 后 UE通过所述小节点接入网络, 分担了宏基站的数据流量, 从而提高移动 宽带通信的带宽、 容量。 图 17为本发明实施例另一种无线宽带通信的方法的信令交互图, 本实 施例包括:
步骤 1701: UE接入 LoMo, 发送 Preamble或显示指示到 LoMo;
步骤 1702: LoMo判断无需重新建立或爹改 SRB 1和 /或 SRB2;

步骤 1704: UE通过一个上行 RRC消息接入网络通知网络连接建立完成, 包括携带连接请求原因, 驻留的 PLMN网络等等。
考虑到 UE的低移动性和室内覆盖的场景, 所以 UE状态以及网络状态 变化可能都比较小, 所以对于很多配置都可以采用默认配置, 包括: 逻辑 信道的配置(传输模式, 逻辑信道优先级等等), SRB的配置(逻辑信道号, RLC的配置参数, 逻辑信道组, 逻辑信道优先级以及优先比特速率等等), MAC层的配置(是否支持 TTI绑定 TTI bundling, HARQ最大重传次数, 緩 沖区报告 BSR, 功率余量报告 PHR, 非连续接收 DRX的配置), 半静态调度 配置, 物理信道配置, 一些 RRC消息的定时器参数。
初始 UE进入 LoMo获取到配置之后, UE存贮这些配置供下次使用。 下 次接入的时候由于 UE的状态以及网络的状态变化都很小, 所以在 RRC连接 建立流程可以大大筒化。
空闲状态用户接入 LoMo, 发起专用的随机接入或显示指示, LoMo根 据专用 preamble码就可以识别 UE的身份;
LoMo根据 UE的身份回随机接入响应消息 (random access response) , 在该消息里用比特表示 SRB1和 /或 SRB2配置是否发生变化, UE根据该比特 确定是否可以用默认的配置进行该 UE的专用资源配置;
如果配置相同, 则说明 UE不需要重新建立 SRB 1和 /或 SRB2, 在随机 接入完成后, UE可以直接发送上行的 RRC消息, 而不需重新进行 RRC连接。 这个上行的 RRC消息可以是新消息也可以是复用现在的 RRC建立完成( RRC connect ion complete ) 消息或者 RRC建立请求 ( RRC connection request ) 消息, 包含 UE ID,建立原因,选择的运营商网络 PLMN和专用 NAS消息等, 修改流程如下图所示。
如果发生切换, 无论是以下哪种切换类型, 切换判决和接纳控制都在 宏基站上, 如图 11和图 12所示:
LoMo切向宏基站;
宏基站切向 LoMo;
从 LoMo切向另夕卜一个 LoMo;
UE从 LTE LoMo切换到 LTE宏基站的过程, 首先由 LTE宏基站发送新 接口包含的测量控制 ( New IF conta ined Measurement Control ) 消息至 LTE LoMo, 然后 LTE LoMo发送测量控制 (Measurement Control ) 消息控 制对应的 UE进行测量并发送测量报告, LTE LoMo在收到对应的测量报告之 后,会发送新接口包含的测量报告( New IF mes sage conta ined Measurement repor t )至 LTE宏基站, 由 LTE宏基站进行切换判决, 如果允许该 UE接 入, 贝' J会发送新接口包含切换命令 ( New IF mes sage conta ined Handover Command )至 LTE LoMo , 由 LTE LoMo发送切换命令 ( Handover Command ) 至对应的 UE, UE切换至对应的 LTE宏基站覆盖区域, 在与 LTE宏基站建 立好连接之后, LTE宏基站通知 LoMo释放相应的资源。
UE从 LTE 宏基站切换到 LTE LoMo 的过程, 首先由 LTE宏基站发送 Measurement Contro l消息控制对应的 UE进行测量并发送测量艮告, 然后 可进一步获取对应的 LoMo的负载情况, 并进行切换的判决, 当确认需要切 换至对应的 LoMo时, 发送 Handover Command至对应的 UE以及 LoMo, UE 在发送切换确认 ( Handover Conf i rm ) 至 LoMo, LoMo在接收到对应的消息 之后, 发送资源释放请求(Resource Release Reques t )至 LTE宏基站, 最后, LTE宏基站释放对应的资源。
