Description

一种数据传输方法、装置及系统
本申请要求于2015年03月27日提交中国专利局、申请号为PCT/CN2015/075323、发明名称为“一种数据传输方法、装置及系统”的PCT国际申请的优先权，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，但同时具有数据速率低、价格高、传输功率大等缺点；而WLAN(Wireless Local Area Networks，无线局域网络)具有数据速率高、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分流无线蜂窝通信系统的数据流量，提高用户体验，实现高效低成本的通信。已知的一种将无线蜂窝网络技术和WLAN技术相互融合的方法为：UE(User Equipment，用户设备)通过基站接入EPC(Evolved Packet Core，演进的分组核心网)，并通过某一PDN-GW(Packet Data Network-Gateway，分组数据网网关)建立PDN(Packet Data Network，分组数据网)连接。随后，UE通过TWAN(Trusted Wireless Local Area Networks Access Network，可信无线局域网络接入网)接入EPC，并且，TWAN能够选择某一PDN-GW创建PDN连接，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，现有技术中WLAN分流无线蜂窝通信系统的数据流量是由UE根据预配策略或者从ANDSF(Access Network Discovery and Selection Function，接入网络发现和选择功能)服务器获取的策略决定，只把业务质量要求不严的业务分流到WLAN网络，无法保证无线蜂窝网络的业务质量。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明 一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
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：GSM(Global System of Mobile communication，全球移动通讯)系统，CDMA(Code Division Multiple Access，码分多址)系统，WCDMA(Wideband Code Division Multiple Access Wireless，宽带码分多址)系统，GPRS(General Packet Radio Service，通用分组无线业务)系统，LTE(Long Term Evolution，长期演进)系统，UMTS(Universal Mobile Telecommunications System，通用移动通信系统)等，本发明并不限定。
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RAN(Radio Access Network，无线接入网)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，蜂窝接入设备可以是基站设备，例如GSM或CDMA中的BTS(Base Transceiver Station，基站收发台)，也可以是WCDMA中的节点B(英文：Node B)，还可以是LTE中的eNB，本发明并不限定。蜂窝接入设备也可以是各种接入网节点的控制节点，例如UMTS中的RNC(Radio Network Controller，无线网口控制器)，或管理多个小基站的控制器等。
在本发明实施例中，非蜂窝接入设备可以是WLAN AP(Wireless Local Area Networks Access Point，无线局域网络接入点)，还可以是 WLAN AC(Wireless Local Area Networks Access Controller，无线局域网络接入控制器)，或其他单独部署的实体WT(WLAN Termination，WLAN结点)，其中，WT可以位于AP，也可以位于AC，也可以是独立的实体。本发明实施例中，非蜂窝接入设备存在两种网络架构：自主管理架构和集中管理架构。自主管理架构又称为“胖”AP架构，WLAN AP负责用户设备接入、用户设备断开、权限认证、安全策略实施、数据转发、数据加密、网络管理等任务，自主控制WLAN AP的配置和无线功能。集中管理架构又称为“瘦”AP架构，管理权一般集中在AC(Access Controller，无线控制器)上。该AC管理用户设备的IP地址、认证和加密等，WLAN AP只具有加密、数据转发、射频功能，不能独立工作。WLAN AP与AC之间采用控制和配置CAPWAP(Control And Provisioning of Wireless Access Points，无线接入点)规范协议。可选的，上述WLAN AP可以与基站一体化设置。因为本发明实施例主要涉及WLAN AP的数据转发功能，故上述WLAN AP的两种网络架构都可以应用。
还需要说明的是，以WLAN WT位于WLAN AP，eNB(evolved Node B，演进型基站)和WLAN WT直连的场景为例，如图1所示，对本发明实施例的eNB、用户设备、WLAN AP中各个协议栈的配置结构进行说明。
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侧实现与该WLAN AP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1所示，eNB第一协议栈可以包括如下协议层：PDCP(Packet Data Convergence Protocol，分组数据汇聚协议)、RLC(Radio Link Control，无线链 路控制层)、MAC(Media Access Control，媒体介入控制层)、PHY(Physical，物理层)。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-U(Xw user，Xw接口用户协议)，具体的Xw-U协议可以使用GTP-U(GPRS Tunnelling Protocol-User Plane，简称：GPRS通道协议-用户面GPRS隧道)协议，进一步的，在GTP-U协议层之上还可以包括新增的适配协议层。本发明中控制面协议栈传输层使用SCTP(Stream Control Transmission Protocol，流控制传输协议)协议、TCP(Transmission Control Protocol，传输控制协议)或者UDP(User Datagram Protocol，用户数据报协议)，应用层采用新定义的XwAP(Xw Application Protocol，Xw接口应用)协议。eNB第二协议栈可以在eNB第一协议栈的PDCP或RLC汇聚。eNB第一协议栈可以在PDCP或RLC分流。在本实施例中，以分流汇聚在第一基站协议栈的PDCP层为例，但本发明对此不做限定。
然后，对WLAN中的协议栈配置结构进行说明。
WLAN协议栈具有WLAN第一协议栈和WLAN第二协议栈。该WLAN第一协议栈用于在该WLAN WT(WLAN Termination，WLAN节点)实现与该eNB之间通信的数据处理，该WLAN第二协议栈用于在该WLAN AP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IEEE(Institute of Electrical and Electronics Engineers，电气和电子工程师协会)来定义。
作为WLAN AP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。WLAN AP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，WI FI协议栈，MAC层、PHY层，可选的，WLAN AP第二协议栈还可以包括LLC(Logical Link Control，逻辑链路控制) 层。
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WLAN AP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LLC层之上还可以包括新增的适配协议层。可选的，用户设备第二协议栈还可以包括LLC层。
在eNB侧，针对eNB第一协议栈分流出的第一部分下行协议数据单元称为第一协议数据单元，在用户设备侧，针对用户设备第一协议栈分流出的第一部分上行协议数据单元称为第二协议数据单元。即分流的上行数据和下行数据均为协议数据单元，本发明不做限制。
同理的，当WT位于AC时，也按照上述方式配置协议栈，AC到AP沿用现有无线局域网通信的协议栈，其余类似，本发明对此不做赘述。
在本发明实施例中，对于非蜂窝网络来说，用户侧终端设备为STA(Station，工作站)，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。
实施例1
本发明实施例提供一种数据传输方法，如图2所示，该方法包括：

无线承载业务质量优先级为无线承载信息对应的QoS(Quality of Service，服务质量)优先级，具体包括ERAB level QoS、DRB level QoS、LC level QoS或者无线承载映射值对应的QoS，其中，ERAB level QoS、DRB level QoS、LC level QoS和无线承载映射值对应的 QoS具有一致性。需要说明的是，无线承载增加列表中包括的QoS优先级为可选的：如果无线承载增加列表中包括QoS优先级，则TEID不同，如果无线承载增加列表中不包括QoS优先级，则TEID可以相同也可以不相同。
S102、蜂窝接入设备接收非蜂窝接入设备发送的GTP-U隧道建立响应信息。
进一步地，GTP-U隧道建立响应信息还包括：蜂窝接入设备与用户设备间的XwAP ID、非蜂窝接入设备与用户设备间的XwAP ID、无线承载允许增加列表；或者，GTP-U隧道建立响应信息还包括：无线承载允许增加列表；或者，GTP-U隧道建立响应信息还包括：蜂窝接入设备与用户设备间的XwAP ID、非蜂窝接入设备与用户设备间的XwAP ID、无线承载允许增加列表，以及无线承载不允许增加列表；或者，GTP-U隧道建立响应信息还包括：无线承载允许增加列表，以及无线承载不允许增加列表。无线承载不允许增加列表为可选，蜂窝接入设备与用户设备间的XwAP ID为可选，非蜂窝接入设备与用户设备间的XwAP ID为可选。

还需要补充的是，当TEID和无线承载信息对应的时候，无线承载信息位于协议数据单元的分组数据信道PDCP报头中、扩展的PDCP报头中，或者新增的协议层报头中。无线承载信息可以是由eNB预先设置在分流的协议数据单元的分组数据信道PDCP报头中、扩展的PDCP报头中，或者新增的协议层报头中的；eNB在分流的协议数据单元中也可以不预先设置无线承载信息，当协议数据单元到了WLAN，由WLAN AP通过TEID找到对应的无线承载信息，将无线承载信息填写至协议数据单元的分组数据信道PDCP报头中、扩展的PDCP报头中，或者新增的适配协议层中，本发明不做限制。
示例性的，以同时具有分流汇聚业务和非蜂窝网业务的场景，PDCP协议层分流汇聚为例，eNB与UE之间通过UE标识经由WLAN AP进行多流汇聚的下行数据传输的过程具体包括：
eNB向WLAN AP发送添加了GTP-U报头的PDCP协议数据单元，如果存在新增的适配协议层，则在GTP-U协议层之前还需添加适配协议层对应的报头，其中，GTP-U报头中的TEID为WLAN AP分配的TEID。无线承载信息位于协议数据单元的PDCP报头中、扩展的PDCP报头中(扩展的PDCP报头标识可在源PDCP报头中指示)，或者新增的协议层报头中，无线承载信息为ERAB ID、DRBID、LCID或者无线承载映射值。可选的，对于TEID不相同，即TEID和无线承载信息对应的情况下，PDCP报头或者扩展的PDCP报头或者新增的适配协议层中也可以不包括无线承载信息。若无线承载信 息为ERAB ID或者无线承载映射值，eNB还需要发送ERAB ID或者无线承载映射值与DRB ID或者LCID的无线承载映射关系至UE。WLAN AP在收到添加了GTP-U报头的PDCP协议数据单元后，获取GTP-U报头中的TEID和UE标识(如UE在WLAN的MAC地址)，并得到TEID和UE标识的映射关系，故WLAN AP可以根据该TEID确定UE的MAC地址。
WLAN AP通过WLAN协议将PDCP数据包发送至UE，同时，WLAN AP把无线承载QoS参数映射到802.11MAC报头中的优先级TID中，同时，WLAN AP在802.11MAC payload中Type设置为PDCP协议对应的协议号。因此对于WLAN AP而言，不需要对带GTP-U报头的数据包进行特殊处理，从而WLAN AP本身也不需要进行改进。可选的，如果PDCP报头或者扩展的PDCP报头或者新增的适配协议层中不包括无线承载信息，则WLAN AP接收到协议数据单元后，通过TEID找到对应的无线承载信息，同时把无线承载信息添加至PDCP报头、扩展的PDCP报头或者新增的适配协议层中。
UE接收到PDCP数据包后，根据802.11MAC payload中的Type判断该协议号是否为PDCP协议对应的协议号，如果该协议号是PDCP对应的协议号，则认为该数据包是从eNB传输过来的，从而把该数据包交由LTE模块PDCP实体处理，由PDCP实体根据PDCP报头、扩展的PDCP报头的无线承载信息来识别承载，然后交由承载对应的PDCP实体；如果GTP-U协议层之上存在适配协议层，则把该数据包交由适配协议层处理，由适配协议层根据适配协议层携带的无线承载信息来识别承载，从而把该数据包交由UE的LTE模块对应无线承载的PDCP实体来处理。
对应的，上行数据传输过程，UE向WLAN AP发送PDCP数据包，无线承载信息位于协议数据单元的PDCP报头中、扩展的PDCP报头中(扩展的PDCP报头标识可在源PDCP报头中指示)、或者新增的协议层报头中，无线承载信息为ERAB ID、DRBID、LCID或者无线承载映射值。
WLAN AP在接收到PDCP数据包后，通过802.11MAC payload中的Type判断该协议号是否为PDCP对应的协议号，如果该协议号是PDCP对应的协议号，则认为该数据包是发送给eNB的，同时，WLAN AP将MAC帧的优先级或者802.3帧中的优先级TID映射至无线承载QoS参数中，然后从PDCP报头、扩展的PDCP报头或者新增的协议层中读取无线承载信息，找到无线承载对应的TEID，由WLAN AP通过GTP-U隧道把数据包发送给eNB。此时，WLAN AP为该PDCP数据包添加GTP-U报头，GTP-U报头中的TEID为eNB分配的TEID，TEID不相同。根据GTP-U中的TEID，WLAN AP可直接将数据包转发到eNB。eNB接收到添加了GTP-U报头的PDCP数据包后，删除GTP-U报头，把该PDCP数据包交由TEID对应承载的PDCP实体来处理。可选的，如果TEID不相同，即TEID是对应承载的，则WLAN AP不读取无线承载信息，直接随机选择TEID，通过TEID对应的GTP-U隧道把数据包发送给eNB的PDCP实体处理，由PDCP实体根据PDCP报头、扩展的PDCP报头或者新增的协议层中的无线承载信息来识别承载，然后交由承载对应的PDCP实体；或者如果TEID相同，即TEID是对应UE的，则WLAN AP不读取无线承载信息，直接通过GTP-U隧道把数据包发送给eNB的PDCP实体处理，由PDCP实体根据PDCP报头、扩展的PDCP报头的无线承载信息来识别承载，然后交由承载对应的PDCP实体；
对于该实施例，可选的，如果非蜂窝网接入设备是WT，且WT是独立的实体，WT和WLAN AC或者WLAN AP直接相连，则如果WT和WLAN AC相连，则401步骤中(GTP-U隧道建立请求消息)中需要增加所述UE标识对应的AC的标识；如果WT和WLAN AP相连，则401步骤中需要增加所述UE标识对应的AP的标识。
本发明实施例提供一种数据传输方法，通过蜂窝接入设备发送GTP-U隧道建立请求信息至非蜂窝接入设备，其中，GTP-U隧道建立请求信息至少包括UE标识，UE标识为UE在非蜂窝的MAC地址或UE在非蜂窝的IP地址；蜂窝接入设备接收非蜂窝接入设备发 送的GTP-U隧道建立响应信息；蜂窝接入设备与UE之间通过UE标识经由非蜂窝接入设备进行多流汇聚的数据传输，其中，蜂窝接入设备与UE之间经由非蜂窝接入设备传输的协议数据单元包括无线承载信息。通过在蜂窝接入设备和非蜂窝接入设备之间建立GTP-U隧道，同时在多流汇聚传输的协议数据单元中标识无线承载信息，完成了蜂窝接入设备与UE之间通过UE标识经由非蜂窝接入设备进行多流汇聚的数据识别与传输，保证了业务连续性。
