Description

一种网络融合的预处理方法、装置及系统
本申请要求于2015年12月31日提交中国专利局、申请号为201511029927.9，发明名称为“一种网络融合的预处理方法、装置及系统”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉通信技术领域，尤其涉及一种网络融合的预处理方法、装置及系统。
背景技术
随着无线通信技术的飞速发展，无线用户数量的急剧增长，以及高清晰多媒体流业务的快速涌现，无线频谱资源越来越稀缺。但与此同时，用户对网络的速率及网络覆盖连续性的要求越来越高，这使得日益增长的无线需求与昂贵有限的授权频谱之间的矛盾日益凸显。目前，许多运营商已通过在非授权频谱上部署无线局域网络(英文：Wireless Local Area Networks，WLAN)来分流无线业务，减轻移动网络的负担。然而，目前运营商的移动网络与WLAN网络是两个独立运营的网络，而且往往WLAN网络处于低利用率的状态。现有技术提供了长期演进(英文：Long Term Evolution，LTE)网络和WLAN网络在无线接入网(英文：Radio Access Network，RAN)侧进行融合的技术。
现有技术中，LTE演进型基站(英文：evolved Node B，eNB)进行LTE网络和WLAN网络的融合时，通常是通过操作管理维护(英文：Operation Administration and maintenance，OAM)等方式获取WLAN网络的信息，并通过广播信令等方式将WLAN网络的信息发送给用户设备(英文：User Equipment，UE)，以供UE将其业务分流到WLAN侧，实现LTE网络和WLAN网络的融合。现有技术中，UE获取WLAN网络的信息耗时较长，使得LTE网络和WLAN网络的融合效率低。此外，由于OAM无法提供WLAN网络的所有信息，使得LTE eNB无法获取OAM获取不到的WLAN网络的特有信息，例如动态变化的WLAN接入点(英文：Access point，AP)信息，提高了LTE网络和WLAN网络的融合的难度，进一步降低了LTE网络和WLAN网络的融合效率。
发明内容

本发明实施例第一方面提供了一种网络融合的预处理方法，其可包括：
当基站确定需要进行第一网络和第二网络的融合时，所述基站向与其连接的用户设备UE发送第二网络连接建立信令，所述第二网络连接建立信令中携带所述第二网络的接入点的接入点信息，所述接入点信息为接入点移动集中的一个，所述接入点移动集包括至少一个接入点中每个接入点的接入点信息，所述每个接入点的接入点信息包括：所述每个无线接入点的服务集识别号SSID、基本服务集识别号BSSID、同质扩展基本服务集识别号HESSID以上三者中的至少一者；
所述基站向所述接入点发送融合准备信令，所述融合准备信令中携带所述UE的标识信息；
当所述基站接收到所述UE发送的第一连接成功信令时，执行所述第一网络和所述第二网络的融合，以将所述UE的业务分流到所述第二网络上；或者

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。
需要说明的是，现有第三代合作伙伴计划(英文：3rd Generation Partnership Project，3GPP)与无线局域网互操作主要集中在核心网层面，无法考虑无线网络负载，容易造成网络负荷不均匀，例如：3GPP引入了接入网发现和选择功能(英文：Access Network Discovery And Selection Function，ANDSF)，ANDSF可以响应用户终端接入网络选择的请求，根据用户终端上报的位置以及用户选网偏好等信息，制定最优的网络选择策略，协助用户终端发现周围可用的无线接入点(或称接入点)，并辅助用户终端进行无线接入点的选择，从而实现业务数据的有效分流。然而，ANDSF的选网策略未考虑到无线网络的信道质量以及负载情况。因此，为了解决前述问题，提出了以下三种方案：
1、RAN可以通过公共通道或专用通道向接入无线接入点的用户终端提供辅助信息，用户终端可以根据RAN提供的辅助信息、用户终端测量到的无线局域网信息，以及从ANDSF获得的策略或者预定义的策略，将业务数据分流至3GPP或WLAN中；
2、RAN提供网络选择和业务数据的分流规则，RAN通过公共通道或专用通道向用户终端提供分流规则中需要使用的参数门限，当不存在ANDSF的策略时，用户终端可以依据RAN提供的分流规则将业务数据分流至3GPP或WLAN中，当同时存在ANDSF的策略时，优先采用ANDSF的策略；
3、RAN可以通过公共通道或专用通道向接入无线接入点的用户终端提供辅助信息，如果支持ANDSF，则用户终端可以根据RAN提供的辅助信息、用户终端测量到的无线局域网信息，以及从ANDSF获得的策略或者预定义的策略，将业务数据分流至3GPP或WLAN中；如果不支持ANDSF，则用户终端可以依据RAN提供的分流规则将业务数据分流至3GPP或WLAN中。
然而，基于目前的三种方案，RAN中的所述基站在获取多个无线接入点的接入点信息时，只能通过OAM设备或预配置方式进行获取，而当有新的无线接入点加入时，所述基站无法及时、动态的获得当前无线接入点的最新状态，因此，通过与无线局域网终端建立通信连接，可以及时、动态的获得与无线局域网终端相连的多个无线接入点的最新状态，进一步提升了与无线接入点的连 接效率，保证了业务数据分流的时效性。
本发明实施例涉及LTE网络和WLAN网络。其中，主要包含基站(eNB)、服务网关(英文：Serving Gateway，SGW)、AP、接入控制器(英文：Access Controller，AC)、WLAN接入网关(英文：WLAN Access Gateway，WAG)、分组数据网关(英文：Packet Data Gateway，PDG)、以及鉴权、授权和计费(AAA)服务器、归属签约用户服务器(英文：Home Subscriber Server，HSS)、分组数据网络网关(英文：PDN Gateway，PGW)等网元。
UE可以接入LTE网络和WLAN网络。其中，UE在LTE网络和WLAN网络中的接入是相互独立的，即UE可以先接入LTE网络而不关心是否有WLAN网络的存在，也可以先接入WLAN网络而不关心是否有LTE网络的存在。
具体实现中，本发明实施例中所描述的网络融合的预处理方法、装置及系统中所描述的第一网络可以为LTE网络，第二网络可为WLAN网络，即本发明实施例中所描述的网络融合具体可为LTE网络和WLAN网络的融合。其中，上述LTE网络和WLAN网络仅是举例，本发明实施例中所描述的网络融合的预处理方法、装置及系统中描述的第一网络和第二网络也可为其他网络，在此不做限制。下面将以LTE网络和WLAN网络为例，对本发明实施例中所描述的网络融合的预处理方法、装置及系统的具体实现方式进行描述。
参见图1，图1是本发明实施例提供的LTE网络和WLAN网络融合的应用场景示意图。图1所示的应用场景中包括LTE eNB、WLAN AP和UE等设备。其中，上述WLAN AP可以是一个或者多个，图1所示场景将以一个为例(例如WLAN AP1)进行说明。上述UE也可以是一个或者多个，图1所示场景将以4个为例(例如UE1、UE2、UE3和UE4)进行说明。UE可在授权频段上工作，例如UE3和UE4，也可在非授权频段上工作，例如UE1和UE2。LTE eNB和WLAN AP之间可通过Xw接口进行信令传输，LTE eNB和UE之间可通过广播等方式进行信令传输，在此不做限制。LTE eNB可将LTE网络和WLAN网络进行融合，从LTE核心网传下来的数据包可有LTE eNB决定哪些数据包经过LTE模块传输给UE，哪些数据包经过与LTE eNB连接的WLAN AP传输给UE。UE需要同时连接LTE网络和WLAN网络，以便进行数据的 传输。此外，一方面，LTE eNB需要引导UE快速地连接到指定的WLAN AP；另一方面，LTE eNB需要及时获知UE何时成功连接到了指定的WLAN AP，以便LTE eNB启动LTE网络和WLAN在RAN侧的深度融合。因此，LTE eNB如何引导UE快速地连接到指定的WLAN AP，以及LTE eNB如何及时获知UE何时成功连接到了指定的WLAN AP，是提高LTE网络和WLAN网络的融合效率的关键。下面将结合图2至图13，对本发明实施例提供的网络融合的预处理方法、装置及系统进行描述。
参见图2，图2是本发明一实施例提供的网络融合的预处理方法的流程示意图。本发明实施例中所描述的方法，包括步骤：
S101，当基站确定需要进行LTE网络和WLAN网络的融合时，所述基站向与其连接的UE发送WLAN连接建立信令。
本发明实施例中所描述的基站具体可为LTE eNB，下面将以LTE eNB为例进行说明。
在一些可行的实施方式中，假设在T1时刻，UE1端产生了大量的视频业务。LTE eNB检测到与其连接的UE1的业务状态之后，当上述UE1的业务量大于阈值时，LTE eNB可确定需要进行LTE网络和WLAN网络的融合，以将UE1的业务分流到WLAN网络上。具体的，LTE eNB可根据小区中各个UE的负载状态设定需要将UE的业务分流到WLAN网络的业务量的阈值。当某个UE的业务量大于上述阈值时，则可确定需要将该UE的业务分流到WLAN网络上，以均衡小区的UE的负载状态。具体实现中，LTE eNB检测到UE1的业务状态之后，可根据上述阈值确定是否需要进行LTE网络和WLAN网络的融合，以将UE的业务分流到WLAN网络上。示例性的，当使用WLAN网络和LTE网络进行数据流分流传输时，一部分数据流在LTE网络中传输，另一部分数据流在WLAN网络中传输，从而起到一个分流的作用，达到提升空口的吞吐率的目的。
在一些可行的实施方式中，当LTE eNB确定需要进行LTE网络和WLAN网络的融合时，LTE eNB可向与其连接的UE发送WLAN连接建立信令(即第二网络连接建立信令)。其中，上述与LTE eNB连接的UE具体可为需要进 行业务分流的UE，例如上述UE1。其中，上述LTE eNB发送给UE的WLAN连接建立信令中携带WLAN AP(即第二网络的AP)的接入点信息，以供UE查找到上述接入点信息对应的WLAN AP，进而建立与上述WLAN AP的连接。
其中，上述WLAN AP具体可为接入点移动集中的一个。需要说明的是，本文通篇所述接入点移动集包括至少一个无线接入点(例如：AP)中每个无线接入点的接入点信息，所述每个无线接入点的接入点信息可以包括但不限于所述每个无线接入点的服务集识别号(Service Set Identifier，SSID)、基本服务集识别号(Basic Service Set Identifier，BSSID)、同质扩展基本服务集识别号(Homogenous Extended Service Set Identifier，HESSID)以上三者中的至少一者。增加接入点移动集的好处是，用户终端(UE)在移动集内部的多个无线接入点范围之间进行移动时，该接入点移动集对接入网侧(例如E-UTRAN，即Evolved UMTS Terrestrial Radio Access Network)是透明的，用户终端无需通知基站(例如eNB或eNodeB)上述移动。在一个无线局域网终端所管理的范围内，可能存在1个或多个接入点移动集，1个接入点移动集下的所有无线接入点共享一个无线局域网终端。示例性的，一个用户终端每次可连接至多一个接入点移动集并进行通信。
进一步的，上述WLAN AP的接入点信息还包括：WLAN AP的介质访问控制(Media Access Control，MAC)地址以及信道二者中的至少一者等。UE可根据上述WLAN AP的接入点信息中的任意一项或者多项找到目标AP。例如，UE可通过上述WLAN AP的SSID(或者BSSID或者HESSID)找到符合条件的一个或者多个AP，还可在上述信道(例如信道3)上查找上述一个或者多个AP中MAC地址为上述WLAN AP的接入点信息中携带的MAC地址(例如00:11:22:35:56:34)的目标AP(例如WLAN AP1，简称AP1)，进而可向上述AP1发送连接请求。
S102，所述基站向WLAN AP发送融合准备信令。
具体实现中，LTE eNB向UE1发送WLAN连接建立信令的同时，还可通过Xw接口向上述WLAN AP的接入点信息对应的AP1发送融合准备信令，已触发上述AP1准备与UE建立连接。其中，上述融合准备信令中携带上述UE的标识信息，例如UE1的接入点信息。其中，上述UE1的接入点信息包 括：UE1的WLAN模块(即第二网络模块)的MAC地址(例如00:11:22:35:56:34)，以及UE的硬件版本信息(例如UE的硬件版本号，如802.11n)等。上述UE的标识信息仅是举例，而非穷举，包含但不限于上述信息。上述AP1接收到LTE eNB发送的融合准备信令之后，则可根据上述融合准备信令中携带的UE的标识信息查找上述硬件版本号对应的一个或者多个UE中MAC地址为00:11:22:35:56:34的UE1，进而可接收上述UE1发送的连接请求。上述AP1成功接受UE1发送的连接请求之后，可向UE1发送连接请求响应，以触发UE1建立与上述AP1的连接。
S103，当所述基站接收到所述UE发送的第一连接成功信令时，执行所述LTE网络和WLAN网络的融合。
具体实现中，UE1接收到AP1发送的连接请求响应之后，可建立与AP1的连接。UE1建立与AP1的连接之后，UE1可向LTE eNB发送连接成功信令(记为第一连接成功信令)，触发LTE eNB进行LTE网络和WLAN网络的融合。
在一些可行的实施方式中，当UE在预设时间内未接收到AP1的连接请求响应时，UE可判定与AP1建立连接失败，进而可搜索指定区域内的其他AP。例如，UE所处的无线局域网的覆盖范围内的其他AP。当UE搜索得到WLAN网络中的其他任一AP(假设为AP2)时，UE可建立与上述搜索到的AP2的连接，并将与其连接的AP2的接入点信息携带在第一连接成功信令中发送给LTE eNB。其中，上述AP2的接入点信息可包括：AP2的SSID、BSSID、HESSID以上三者中的至少一者，进一步的，上述AP2的接入点信息还可包括：AP2的MAC地址和/或信道等，在此不做限制。
LTE eNB接收到UE1发送的第一连接成功信令时，可确定UE1和AP1(或者AP2)已成功建立连接，进而可开始进行LTE网络和WLAN网络的融合。LTE eNB进行LTE网络和WLAN网络的融合之后，则可以将UE1的业务分流到AP1(或者AP2)上。例如，可以将需要发送给UE1的承载视频数据的数据承载(DRB,Data Radio Bear)中的其中50MBytes的数据包通过LTE网络发送给UE1，将另外50Mbytes的数据包通过WLAN AP1发送给UE1，实现Bear级别的业务分流。
S104，当所述基站接收到所述AP发送的第二连接成功信令时，执行所述LTE网络和WLAN网络的融合。
进一步的，在一些可行的实施方式中，AP1成功接受UE1发送的连接请求之后，还可向LTE eNB发送成功连接信令(即为第二成功连接信令)，告知LTE eNB自己已经成功接受了UE1的连接申请。
LTE eNB向UE1发送WLAN连接建立信令，并向AP发送融合准备信令之后，还可接收AP1发送的第二连接成功信令，以根据上述第二连接成功信令确定UE1和AP1已成功建立连接，进而可开始进行LTE网络和WLAN网络的融合。LTE eNB进行LTE网络和WLAN网络的融合之后，则可以将UE1的业务分流到AP1上。即，LTE eNB可根据UE1发送的第一连接成功信令确定UE1和AP1已成功建立连接，也可根据AP发送的第二连接成功信令确定UE1和AP1已成功建立连接，进而可进行LTE网络和WLAN网络的融合。
在本发明实施例中，LTE eNB可向需要进行业务分流的UE发送WLAN连接建立信令，将用于承载上述UE的业务的WLAN AP的接入点信息携带在上述WLAN连接建立信令中，以引导UE快速查找并连接到上述WLAN AP上。同时，LTE eNB可向WLAN AP发送融合准备信令，将上述UE的标识信息携带在上述融合准备信令中发送给WLAN AP，以引导WLAN AP快速识别并接受上述UE发送的连接请求，建立UE和WLAN AP的连接，可降低LTE网络中的UE获取WLAN网络的WLAN AP的信息获取难度，提高UE和WLAN AP建立连接的效率。LTE eNB还可根据UE或者WLAN AP发送的成功连接信令，及时获知UE已经成功与WLAN AP建立连接，进而可进行LTE网络和WLAN网络的融合，以将UE的业务分流到WLAN AP上，提高LTE网络和WLAN网络融合的效率。
参见图3，图3是本发明另一实施例提供的网络融合的预处理方法的流程示意图。本发明实施例中所描述的方法，包括步骤：

在一些可行的实施方式中，假设在T1时刻，UE1端产生了大量的视频业务。当上述UE1的业务量大于阈值时，可通过LTE eNB进行LTE网络和WLAN 网络的融合，以将UE1的业务分流到WLAN网络上。
具体实现中，LTE网络上的UE(例如UE1)可接收基站发送的WLAN连接建立信令，上述WLAN连接建立信令中携带WLAN AP(即第二网络的AP)的接入点信息，以供UE查找到上述接入点信息对应的WLAN AP，进而建立与上述WLAN AP的连接。其中，上述WLAN AP的接入点信息可参见上述实施例中所描述的内容，在此不再赘述。
S202，所述UE根据所述接入点信息查找所述接入点并向所述接入点发送连接请求。
在一些可行的实施方式中，UE可根据上述WLAN AP的接入点信息中的任意一项或者多项找到目标AP。例如，UE可通过上述WLAN AP的SSID(或者BSSID或者HESSID)找到符合条件的一个或者多个AP，还可在上述信道(例如信道3)上查找上述一个或者多个AP中MAC地址为上述WLAN AP的接入点信息中携带的MAC地址(例如00:11:22:35:56:34)的目标AP(例如WLAN AP1，简称AP1)，进而可向上述AP1发送连接请求，以建立与上述AP1的连接。
S203，当所述UE接收到所述AP的连接请求响应时，建立与所述AP的连接，并向所述基站发送第一连接成功信令。
具体实现中，AP1成功接受UE1发送的连接请求之后，可向UE1发送连接请求响应，以触发UE1建立与上述AP1的连接。UE1接收到AP1发送的连接请求响应之后，可建立与AP1的连接。UE1建立与AP1的连接之后，可向LTE eNB发送连接成功信令(记为第一连接成功信令)，触发LTE eNB进行LTE网络和WLAN网络的融合。
在一些可行的实施方式中，当UE1在预设时间内未接收到AP1的连接请求响应时，UE1可判定与AP1建立连接失败，进而可搜索指定区域内的其他AP。例如，UE1所处的无线局域网的覆盖范围内的其他AP。当UE1搜索得到WLAN网络中的其他任一AP(假设为AP2)时，UE1可建立与上述搜索到的AP2的连接，并将与其连接的AP2的接入点信息携带在第一连接成功信令中发送给LTE eNB。其中，上述AP2的接入点信息可包括：AP2的SSID、BSSID、HESSID以上三者中的至少一者，进一步的，上述AP2的接入点信息 还可包括：AP2的MAC地址和信道等，在此不做限制。
具体实现中，本发明实施例中所描述的UE可执行上述实施例中所描述的UE(例如UE1)的实现方式，具体可参见上述实施例中各个步骤所描述的实现方式，在此不再赘述。
在本发明实施例中，UE可根据LTE eNB发送的WLAN连接建立信令中携带的WLAN AP的接入点信息快速查找并连接到上述WLAN AP上，可UE获取WLAN网络的WLAN AP的信息获取难度，提高UE和WLAN AP建立连接的效率，进而可触发LTE eNB快速进行LTE网络和WLAN网络的融合，提高了LTE网络和WLAN网络融合的效率。
参见图4，图4是本发明另一实施例提供的网络融合的预处理方法的流程示意图。本发明实施例中所描述的方法，包括步骤：
S301，WLAN AP接收基站发送的融合准备信令。
具体实现中，LTE eNB向UE1发送WLAN连接建立信令的同时，还可通过Xw接口向上述WLAN AP的接入点信息对应的AP(例如AP1)发送融合准备信令，已触发上述AP1准备与UE建立连接。其中，上述融合准备信令中携带上述UE的标识信息，例如UE1的接入点信息。其中，上述UE1的接入点信息包括：UE1的WLAN模块(即第二网络模块)的MAC地址(例如00:11:22:35:56:34)，以及UE的硬件版本信息(例如UE的硬件版本号，如802.11n)等。上述UE的标识信息仅是举例，而非穷举，包含但不限于上述信息。
S302，当所述AP接收到UE发送的连接请求，所述AP接受所述UE的连接请求并向所述UE发送连接请求响应。

参见图5，图5是本发明实施例提供的网络融合的预处理基站的一结构示意图。本发明实施例中所描述的预处理基站具体可为本发明实施例中所描述的LTE eNB，其可包括：

在一些可行的实施方式中，假设在T1时刻，UE1端产生了大量的视频业务。检测单元12检测到与LTE eNB连接的UE1的业务状态之后，当上述UE1的业务量大于阈值时，可确定需要进行LTE网络和WLAN网络的融合，以将UE1的业务分流到WLAN网络上。具体的，检测单元12可根据小区中各个UE的负载状态设定需要将UE的业务分流到WLAN网络的业务量的阈值。当某个UE的业务量大于上述阈值时，则可确定需要将该UE的业务分流到WLAN网络上，以均衡小区的UE的负载状态。具体实现中，检测单元12检测到UE1的业务状态之后，可根据上述阈值确定是否需要进行LTE网络和WLAN网络的融合，以将UE的业务分流到WLAN网络上。示例性的，当使用WLAN网络和LTE网络进行数据流分流传输时，一部分数据流在LTE网络中传输，另一部分数据流在WLAN网络中传输，从而起到一个分流的作用，达到提升空口的吞吐率的目的。
在一些可行的实施方式中，当检测单元12确定需要进行LTE网络和WLAN网络的融合时，发送单元10可向与LTE eNB连接的UE发送WLAN连接建立信令(即第二网络连接建立信令)。其中，上述与LTE eNB连接的UE具体可为需要进行业务分流的UE，例如上述UE1。其中，上述发送单元10发送给UE的WLAN连接建立信令中携带WLAN AP(即第二网络的AP)的接入点信息，以供UE查找到上述接入点信息对应的WLAN AP，进而建立与上述WLAN AP的连接。
其中，上述WLAN AP具体可为接入点移动集中的一个。UE可通过上述 WLAN AP的SSID(或者BSSID或者HESSID)找到符合条件的一个或者多个AP，进而可在上述信道(例如信道3)上查找上述一个或者多个AP中MAC地址为上述WLAN AP的接入点信息中携带的MAC地址(例如00:11:22:35:56:34)的目标AP(例如WLAN AP1，简称AP1)，进而可向上述AP1发送连接请求。
具体实现中，发送单元10向UE1发送WLAN连接建立信令的同时，还可通过Xw接口向上述WLAN AP的接入点信息对应的AP1发送融合准备信令，已触发上述AP1准备与UE建立连接。其中，上述融合准备信令中携带上述UE的标识信息，例如UE1的接入点信息。其中，上述UE1的接入点信息包括：UE1的WLAN模块(即第二网络模块)的MAC地址(例如00:11:22:35:56:34)，以及UE的硬件版本信息(例如UE的硬件版本号，如802.11n)等。上述UE的标识信息仅是举例，而非穷举，包含但不限于上述信息。上述AP1接收到LTE eNB发送的融合准备信令之后，则可根据上述融合准备信令中携带的UE的标识信息查找上述硬件版本号对应的一个或者多个UE中MAC地址为00:11:22:35:56:34的UE1，进而可接收上述UE1发送的连接请求。上述AP1成功接受UE1发送的连接请求之后，可向UE1发送连接请求响应，以触发UE1建立与上述AP1的连接。
具体实现中，UE1接收到AP1发送的连接请求响应之后，可建立与AP1的连接。UE1建立与AP1的连接之后，UE1可向LTE eNB发送连接成功信令(记为第一连接成功信令)，触发LTE eNB进行LTE网络和WLAN网络的融合。
在一些可行的实施方式中，当UE在预设时间内未接收到AP1的连接请求响应时，UE可判定与AP1建立连接失败，进而可搜索指定区域内的其他AP。例如，UE所处的无线局域网的覆盖范围内的其他AP。当UE搜索得到WLAN网络中的其他任一AP(假设为AP2)时，UE可建立与上述搜索到的AP2的连接，并将与其连接的AP2的接入点信息携带在第一连接成功信令中发送给LTE eNB。其中，上述AP2的接入点信息可包括：AP2的SSID、BSSID、HESSID以上三者中的至少一者，进一步的，上述AP2的接入点信息还可包括：AP2的MAC地址和信道等，在此不做限制。
处理单元11接收到UE1发送的第一连接成功信令时，可确定UE1和AP1(或者AP2)已成功建立连接，进而可开始进行LTE网络和WLAN网络的融合。LTE eNB进行LTE网络和WLAN网络的融合之后，则可以将UE1的业务分流到AP1(或者AP2)上。例如，可以将需要发送给UE1的承载视频数据的数据承载(DRB,Data Radio Bear)中的其中50MBytes的数据包通过LTE网络发送给UE1，将另外50Mbytes的数据包通过WLAN AP1发送给UE1，实现Bear级别的业务分流。
进一步的，在一些可行的实施方式中，AP1成功接受UE1发送的连接请求之后，还可向LTE eNB发送成功连接信令(即为第二成功连接信令)，告知LTE eNB自己已经成功接受了UE1的连接申请。
发送单元10向UE1发送WLAN连接建立信令，并向AP发送融合准备信令之后，处理单元11还可接收AP1发送的第二连接成功信令，以根据上述第二连接成功信令确定UE1和AP1已成功建立连接，进而可开始进行LTE网络和WLAN网络的融合。LTE eNB进行LTE网络和WLAN网络的融合之后，则可以将UE1的业务分流到AP1上。即，LTE eNB可根据UE1发送的第一连接成功信令确定UE1和AP1已成功建立连接，也可根据AP发送的第二连接成功信令确定UE1和AP1已成功建立连接，进而可进行LTE网络和WLAN网络的融合。
在本发明实施例中，LTE eNB可向需要进行业务分流的UE发送WLAN连接建立信令，将用于承载上述UE的业务的WLAN AP的接入点信息携带在上述WLAN连接建立信令中，以引导UE快速查找并连接到上述WLAN AP上。同时，LTE eNB可向WLAN AP发送融合准备信令，将上述UE的标识信息携带在上述融合准备信令中发送给WLAN AP，以引导WLAN AP快速识别并接受上述UE发送的连接请求，建立UE和WLAN AP的连接，可降低LTE网络中的UE获取WLAN网络的WLAN AP的信息获取难度，提高UE和WLAN AP建立连接的效率。LTE eNB还可根据UE或者WLAN AP发送的成功连接信令，及时获知UE已经成功与WLAN AP建立连接，进而可进行LTE网络和WLAN网络的融合，以将UE的业务分流到WLAN AP上，提高LTE网络和WLAN网络融合的效率。

具体实现中，AP1成功接受UE1发送的连接请求之后，可向UE1发送连接请求响应，以触发UE1建立与上述AP1的连接。发送单元21接收到AP1发送的连接请求响应之后，可通过连接单元22建立UE1与AP1的连接。连接单元22建立UE1与AP1的连接之后，发送单元21可向LTE eNB发送连接成功信令(记为第一连接成功信令)，触发LTE eNB进行LTE网络和WLAN网络的融合。
在一些可行的实施方式中，当接收单元20在预设时间内未接收到AP1的连接请求响应时，UE1可判定与AP1建立连接失败，进而可通过搜索单元23搜索指定区域内的其他AP。例如，UE1所处的无线局域网的覆盖范围内的其他AP。当搜索单元23搜索得到WLAN网络中的其他任一AP(假设为AP2)时，连接单元22可建立UE1与上述搜索到的AP2的连接，并通过发送单元21将与UE1连接的AP2的接入点信息携带在第一连接成功信令中发送给LTE eNB。其中，上述AP2的接入点信息可包括：AP2的SSID、BSSID、HESSID以上三者中的至少一者，进一步的，上述AP2的接入点信息还可包括：AP2的MAC地址和信道等，在此不做限制。
