Description

一种数据传输方法、装置及系统 技术领域
本发明涉及通信领域，尤其涉及一种数据传输方法、装置及系统。
背景技术
随着智能移动终端的普及和移动应用的迅速发展，用户使用移动数据的场合大大增多，导致现有的网络越来越难以满足移动数据流量增长的需求。通常的，无线蜂窝网络具有覆盖范围广，支持高速移动等优点，但同时具有数据传输速率低、价格高、传输功率大等缺点；而无线局域网络(Wireless Local Area Networks，WLAN)具有数据传输速率高、价格低、传输功率小等优点，但同时具有覆盖范围小等缺点。
为了满足移动数据流量增长的需求，现有技术将无线蜂窝网络技术和WLAN技术相互融合，利用WLAN分流无线蜂窝网络的数据流量，提高用户体验，实现高效低成本的通信。目前，第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)提出了一种长期演进无线局域网络汇聚(Long Term Evolution Wireless Local Area Networks aggregation，LWA)技术，能够在基站和无线局域网络端点(Wireless Local Area Networks termination，WT)之间建立用户层面的通用无线分组业务隧道协议(General Packet Radio Service Tunnelling Protocol-User Plane，GTP-U)隧道，并通过GTP-U隧道传输数据，从而实现无线蜂窝网络技术和WLAN技术的相互融合，实现WLAN分流的技术。
然而，现有的LWA技术只能够传输下行数据，当用户设备(User Equipment，UE)需要发送上行数据时，无法通过基站和WT之间建立的GTP-U隧道传输分流的数据至基站。
发明内容
本发明的实施例提供一种数据传输方法、装置及系统，非蜂窝接入设备能够为UE分配非蜂窝网的资源，使得UE通过非蜂窝接入设备向蜂窝接入设备发送上行数据。

另外，本文中术语“系统”和“网络”在本文中常被可互换使用。本文中术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。
需要说明的是，本发明的技术方案可以应用于无线蜂窝网络的各种通信系统，例如：全球移动通讯(Global System of Mobile communication，GSM)系统，码分多址(Code Division Multiple Access，CDMA)系统，宽带码分多址(Wideband Code Division Multiple Access Wireless，WCDMA)系统，通用分组无线业务(General Packet Radio Service，GPRS)系统，长期演进(Long Term Evolution，LTE)系统，通用移动通信系统(Universal Mobile Telecommunications System，UMTS)等，本发明并不限定。
本发明实施例提供的基于LWA技术的通信系统的架构图如图1所示，通信系统分为三个网元，演进分组核心网(Evolved Packet Core，EPC)设备、演进型基站(Evolved Node B，eNode B)和WLAN结点(WLAN Termination，WT)。EPC负责核心网部分，包括移动性管理实体(Mobility Management Entity，MME)和服务网关(Serving Gateway，S-GW)，其中，MME进行信令处理，S-GW进行数据处理。eNode B和WT负责接入网部分，也称演进的通用陆地无线接入网络(Evolved Universal Terrestrial Radio Access Network，E-UTRAN)。eNode B可以统称为蜂窝接入设备，WT可以统称为非蜂窝接入设备。本发明实施例提供的数据传输方法就是在蜂窝接入设备、非蜂窝接入设备和UE之间进行的。同时，本发明实施例提供的数据传输方法适用于蜂窝接入设备和非蜂窝接入设备共站，以 及蜂窝接入设备和非蜂窝接入设备非共站两种场景中，本发明不做限制。
在本发明实施例中，UE也可称之为移动终端(英文：Mobile Terminal)、移动用户设备等，可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，UE可以是移动终端，如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机，例如，可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语言和/或数据，本发明并不限定。

在本发明实施例中，非蜂窝网络也可以称为非蜂窝系统，可以简称为“非蜂窝”，本发明实施例中出现的“非蜂窝”即指代非蜂窝网络或者非蜂窝系统。
对于非蜂窝网络来说，用户侧终端设备为工作站(Station，STA)，而对于无线蜂窝网络来说，用户侧终端设备为UE。在本发明实施例的非蜂窝网络和无线蜂窝网络组成的异构网络场景中，用户侧终端设备可以称为UE或STA，能够接收两个网络的服务，为了方便描述，以下统称为UE。
需要说明的是，本发明实施例的eNB、UE和WT中各个协议栈的配置结构可以分为三种：第一种是eNB和UE的协议栈包括LWAAP协议层；第二种是eNB、UE和WT中各个协议栈包括LWAAP协议层；第三种是UE和WT的协议栈包括LWAEP协议层。下面，首先对这三种eNB、UE和WT中各个协议栈的配置结构进行说明。
对于eNB和UE的协议栈包括LWAAP协议层的情况，如图2所示。eNB和UE的协议栈包括LWAAP协议层的情况与现有的协议栈的配置结构相同。
对于eNB、UE和WT中各个协议栈包括LWAAP协议层的情况，如图3所示。
首先，对eNB中的协议栈配置结构进行说明：
eNB协议栈可以有eNB第一协议栈和eNB第二协议栈，该eNB第一协议栈用于在eNB侧实现与该用户设备之间通信的数据处理，该eNB第二协议栈用于在eNB侧实现与WT之间通信的数据处理。作为eNB第一协议栈，例如现有能够实现eNB与用户设备之间的通信协议栈均在保护范围内。作为eNB第二协议栈，可以通过接口直接聚合在eNB第一协议栈的至少一个协议层上。
eNB第一协议栈和eNB第二协议栈可以包括用户面协议栈，也可以包括用户面协议栈和控制面协议栈。例如，如图3所示，eNB第一协议栈可以包括如下协议层：分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)、无线链路控制层(Radio Link Control，RLC)、媒体介入控制层(Media Access Control，MAC)、物理层(Physical，PHY)。作为eNB第二协议栈，可以包括用户面协议栈，也可以包括控制面协议栈，本发明中用户面协议栈的传输层采用新定义的Xw接口用户协议(Xw user，Xw-U)，具体的Xw-U协议可以使用GPRS通道协议-用户面GPRS隧道(GPRS Tunnelling Protocol-User Plane，GTP-U)协议。本发明中控制面协议栈传输层使用流控制传输协议(Stream Control Transmission Protocol，SCTP)协议、传输控制协议(Transmission Control Protocol，TCP)或者用户数据报协议(User Datagram Protocol，UDP)，应用层采用新定义 的Xw接口应用(Xw Application Protocol，XwAP)协议。eNB第二协议栈可以在eNB第一协议栈的PDCP汇聚。eNB第一协议栈可以在PDCP分流。可选的，eNB第二协议栈还存在一个LWAAP协议层，LWAAP协议层位于GTP-U层之上。
然后，对WT中的协议栈配置结构进行说明。
WT协议栈具有WT第一协议栈和WT第二协议栈。该WT第一协议栈用于在该WLAN WT实现与该eNB之间通信的数据处理，该WT第二协议栈用于在该WT侧实现与该用户设备之间通信的数据处理。具体的，若WT位于WLAN AP，则WT和WLAN AP之间通信内部实现，若WT独立于WLAN AP，则WT和WLAN AP之间的通信协议栈由电气和电子工程师协会(Institute of Electrical and Electronics Engineers，IEEE)来定义。
作为WT第一协议栈，可以包括用户面协议栈，也可以包括控制面协议栈和用户面协议栈，本发明中用户面协议栈的传输层采用Xw-U，具体的Xw-U协议可以使用GTP-U协议，本发明中控制面协议栈传输层使用SCTP协议，应用层采用新定义的XwAP协议。WT第二协议栈可以使用例如现有的无线局域网通信的协议栈，例如，WIFI协议栈，MAC层、PHY层，可选的，WT第二协议栈还可以包括逻辑链路控制(Logical Link Control，LLC)层，在MAC层之上还存在一个LWAAP协议层，如果有LLC层，那么LWAAP协议层在LLC层之上。
最后，对用户设备中的协议栈配置结构进行说明：
用户设备协议栈可以有用户设备第一协议栈和用户设备第二协议栈，该用户设备第一协议栈用于在用户设备侧实现与eNB之间通信的数据处理，该用户设备第二协议栈用于在用户设备侧实现与WT之间通信的数据处理。其中，该用户设备第二协议栈与该用户设备第一协议栈的至少一个协议层相连。具体的，用户设备第二协议栈可以包括如下协议层：MAC层，PHY层，进一步的，在MAC层之上还可以包括LWAAP协议层。可选的，用户设备第二协议栈还可以包括LLC层，如果包括LLC层，那么LWAAP协议层可以在LLC层 之上。
对于UE和WT的协议栈包括LWAEP协议层的情况，如图4所示。
首先，对eNB中的协议栈配置结构进行说明：
eNB中的协议栈配置结构与图3中eNB中的协议栈配置结构类似，与其不同的是：eNB第二协议栈不存在LWAAP协议层。
然后，对WT中的协议栈配置结构进行说明。
WT中的协议栈配置结构与图3中WT中的协议栈配置结构类似，与其不同的是：在MAC层之上还存在一个新的协议层(LWAEP)，如果有LLC层，那么新的协议层在LLC层之上。
最后，对用户设备中的协议栈配置结构进行说明：
用户设备中的协议栈配置结构与图3中用户设备中的协议栈配置结构类似，与其不同的是：在MAC层之上还可以包括新增的适配协议层(LWAEP)。可选的，用户设备第二协议栈还可以包括LLC层，如果包括LLC层，那么新增的适配协议层可以在LLC层。
