Description

AP组信息处理方法及eNB 技术领域
本文涉及但不限于无线通信领域，尤其涉及一种AP组信息处理方法及eNB。
背景技术
随着无线通信技术和标准的不断演进，移动分组业务得到了巨大的发展，单用户设备的数据吞吐能力不断在提升。以长期演进(Long Term Evolution，LTE)系统为例，在20M带宽内可以支持下行最大速率100Mbps的数据传输，后续的增强的LTE(LTE Advanced)系统中，数据的传输速率将进一步提升，甚至可以达到1Gbps。
用户设备数据业务量膨胀式的增长，让现有的网络资源渐渐力不从心，尤其是在新一代通信技术(比如3G、LTE)还无法广泛布网的情况下，随之而来的是用户速率和流量需求无法满足，用户体验的变差。如何预防和改变这一情况是运营商必须考虑的问题，一方面需要加快新技术的推广和网络部署；另一方面，希望能够通过对现有网络和技术进行增强，以达到快速提升网络性能的目的。众所周知的，在第三代合作伙伴计划(The 3rd Generation Partnership Project，3GPP)提供的无线网络技术之外，当前已经普遍应用的无线局域网(Wireless Local Area Network，WLAN)，尤其是基于电气和电子工程师学会(Institute of Electrical and Electronics Engineers，IEEE)802.11标准的无线局域网已经在家庭、企业甚至是互联网被广泛应用于热点接入覆盖。其中由WiFi联盟(Wi-Fi Alliance)提出的技术规范应用最广，因此实际中WiFi网络经常跟基于IEEE 802.11标准的WLAN网络划等号，在不引起混淆的情况下，后文也采用WiFi模块来描述网络节点中支持WLAN的无线收发和处理模块。
在这一前提下，有的运营商和公司已经提出将WLAN与现有3GPP网络进行融合，实现联合传输，以达到负荷分流和提高网络性能的目的。3GPP SA2 通过了接入网发现和选择功能单元(Access Network Discovery and Selection Functions，ANDSF)方案，提供了一种根据运营商策略为用户设备选择目标接入网络的模式。
通信协议3GPP R10定义了ANDSF标准，ANDSF作为接入锚点实现智能选网，通过网络与用户设备的交互协同，实现网络接入的有效分流，符合未来多网协同的运营方向。ANDSF基于网络负荷、用户设备能力、用户签约情况等信息制定策略，帮助用户设备用户选择最佳接入的网络制式，实现多种接入方式的协同运营。ANDSF既可以单独部署，也可与其它网元合设。目前，业界主流观点认为ANDSF可以部署在PCC设备上方案。
ANDSF是一个基于核心网的WLAN互通方案，并没有考虑到对接入网的影响，此外由于ANDSF是一个相对静态的方案，不能很好对网络负荷与信道质量动态变化的情况进行适应，因此在3GPP接入网组也开展了WLAN huto9ng讨论。在3GPP R12WLAN和3GPP无线互操作中，执行WLAN分流的规则和触发的机制被引入。
然而，核心网机制和来自无线接入网的辅助信息机制不能提供给网络侧实时地使用负荷和信道条件从而合并使用无线资源。另外，来自相同承载的数据不能同时在3GPP和WLAN链路上服务。因此WLAN与3GPP网络集成的需求在无线接入网络(Radio Access Network，RAN)65次全会被重新提出。
相比目前已经研究的依赖于策略和触发的WLAN分流方案，RAN层次聚合的WLAN与3GPP网络集成，简称WLAN和3GPP网络紧耦合，类似于载波聚合和双连接，为总体系统提供更好地双连接上资源的控制和利用。在无线层的紧集成和聚合允许更多的实时联合调度WLAN与3GPP网络的无线资源，因此提高用户服务质量(Quality of Service，QoS)和整体系统容量。通过更好管理用户间的无线资源，能增加所有用户的集体吞吐量和提供整个系统容量。基于实时信道条件和系统使用情况下，每个链路调度决定能够做到每一个包的层次。用户面锚定在可靠的LTE网络，可以通过回退到LTE网络来提高性能。
WLAN和3GPP网络紧耦合能应用于同地协作场景(eNB与无线接入点(Access Point，AP)之间通过内部接口完成RAN层集成操作)和非同地协 作场景(eNB与AP之间通过外部接口完成RAN层集成操作)，这个本质上分别类似于3gpp载波聚合和双连接。
在WLAN和3GPP网络紧耦合应用场景中，AP可划分为多个AP组；用户设备在同一个AP组内的移动，可以不通知3GPP网络，即对LTE网络的网元可是透明的。但是用户设备在不同的AP组之间的移动，可能需要3GPP网络的网元参与控制，以更好的均衡负载及提高传输效率或质量或系统容量。
现在就引来一个新的问题，AP组如何传输给用户设备(User Equipment，UE)以使UE能够更好的AP组内进行切换，实现LTE网络与WLAN网络之间的紧耦合。

在阅读并理解了附图和详细描述后，可以明白其他方面。
附图概述

图2为本发明实施例提供的AP组信息处理方法的流程示意图之一；
图3为本发明实施例提供的获取所述AP组信息的流程示意图；
图4为本发明实施例提供的eNB的结构示意图；
图5为本发明实施例提供的AP组信息处理方法的流程示意图之二；

本发明的实施方式
图1所示，为一个WLAN和3GPP网络耦合的结构示意图。即3GPP网络的演进型基站eNB与WLAN的WLAN网元之间通过外部接口Xw完成RAN层集成操作。所述WLAN网元包括无线局域网终结点(Wireless LAN Termination，WT)。所述WT可以为集成在其他WLAN网元(如图1中的AP)上的一个逻辑节点，也可以是单独设置的实体节点。所述WT作为通过接口Xw与LTE网络中的网元进行信息交互。
在本申请实施例中UE在同一AP组内可以在不告知LTE网络的情况下自由移动或基于UE内部的自动控制策略进行AP切换，UE在不同的AP组或包括WT的AP组移动时，需要告知LTE网络，由其进行控制，以更好的实现WLAN和3GPP网络的耦合。这样的话，UE就要知道当前的AP组的相关信息，如果UE不知道当前AP组的相关信息，UE无法实现在同一AP组内的AP之间的自由移动，LTE的网元也要知道AP组的信息，如果LTE网元不知道AP组的信息，LTE无法实现对UE在AP之间切换的控制和决策。
通过分析图1发现，可以将AP的AP组信息通过WT下发给UE，也可以通过eNB下发给UE，但是通过WT下发给UE就需在WT与UE之间的通信中增加信令，显然这涉及WLAN的通信协议的修改；而目前在通信领域对WLAN的通信协议的修改是非常严格的，也是难度非常大的，且不管AP组的划分是由LTE网络还是WLAN完成的，AP组的AP组信息都要备份到LTE，故基于此，本申请实施例所述的AP组信息处理方法，一方面避免修改WLAN的通信协议，另一方面减少AP组信息的传输次数和信令开销，由eNB将AP组信息传输给UE。显然首先不用修改WLAN网络与UE之间的通信协议，eNB在向UE传输的过程中，首先自行获取AP组信息，这样的话，可以通过一次AP组信息的传输，eNB和UE都获得了所述AP组信息，相对于分别传输给eNB和UE的AP组信息，减少了AP组信息的传输次数及信令开销。
以下结合说明书附图及具体实施例对本发明的技术方案做进一步的详细 阐述。
如图2所示，本实施例提供一种AP组信息处理方法，，所述方法包括：
步骤S110：eNB获取AP组的AP组信息；
步骤S120：通过eNB的空口下行消息将所述AP组信息发送给用户设备。
所述eNB为演进型基站，为LTE网络的接入网元。所述eNB能够与UE进行移动通信。
在本实施例中，所述eNB首先自行获取所述AP组的AP组信息。所述AP组信息包括AP组的标识信息、AP的个数、AP的标识信息、及每个AP使用频点信息。所述AP组的标识信息可包括所述AP组的组号或名称等信息。所述AP标识信息可包括基本服务集标识符(Basic Service Set Identifier，BSSID)、服务集标识符(Service Set Identifier,SSID)及媒体访问控制地址(Medium Access Control，MAC)的一个或多个。所述AP使用频点信息能够用于表明对应AP的使用频段。
步骤S120中，基站在获取到所述AP组信息之后，向终端发送所述AP组信息，而不是由WLAN网络的网元下发给所述UE。这样的话，UE就能够从eNB获取所述AP组信息，就不用在WLAN的通信协议中增加发送所述AP组信息的通信协议，而是由eNB发送所述AP组信息，能够达到简化AP组信息的传输的特点。
所述eNB获取所述AP组信息的方式至少有两种：
第一种：
所述步骤S110可包括：eNB接收无线局域网终结点WT发送的所述AP组信息。
在本实施例中首先限定了eNB是通过从WT接收的所述AP组信息。所述AP组信息可能是由WLAN中的任意一个网元形成的，如所述WT或AP或访问控制器(Access Controller，AC)形成的。与此同时，WLAN形成了所述AP组信息之后，只用向eNB发送所述AP组信息即可，不用向UE发送所述AP组信息；这样就简化了WLAN这一侧AP组信息的发送。
第二种：
如图3所示，所述步骤S110可包括：
步骤S111：eNB接收辅助信息；所述辅助信息包括用户设备发送的第一辅助信息和/或无线局域网终结点WT形成的第二辅助信息；
步骤S112：eNB基于所述辅助信息，按照分组策略进行AP分组形成AP组；
步骤S113：形成所述AP组的AP组信息。
本实施例中所述eNB自行形成所述AP组信息，若eNB自行形成的所述AP组信息，虽然可以通过Xw接口先发送给WT，再由WT通过WLAN与UE的连接发送给UE，但是显然这种发送方式，相对于由eNB直接传输给UE更加繁琐，也不用修改WLAN的通信协议。
在本实施例中所述eNB会接收所述WT和/或所述UE发送的辅助信息，来自动进行AP分组，形成AP组，最后基于所述AP组形成所述AP组信息。
所述第一辅助信息包括以下至少其中之一：

AP会发出扫描信号供UE扫描，以使UE发现AP以便接入该AP。
UE可以关联到的AP为UE能够扫描到并接入的AP；有一些AP是局限于授权或AP的状态，其中，局限于AP的状态包括AP本身负荷已达到极限，处于拒绝接入状态，UE虽然能够扫描到但并非能够接入的AP。
所述用户设备在指定时间内使用每个AP的使用状况信息可包括：UE在指定时间内接入哪些AP，利用了哪些AP提供服务，访问每个AP的频次等。UE在用户指示下偏好访问哪些AP，这些使用状况信息可包括UE的AP使用记录信息等。
所述AP的关联时间信息表明UE与AP建立连接的时间长短的信息，或UE与AP建立关联的时刻点等信息。
AP的负荷状况信息表明的是AP的负荷状况，表明AP是否能够有空闲资源关联(连接)或为更多的UE提供WLAN服务等信息。
关联时间大于预设关联门限的AP的AP信息，可用于表明哪些AP与UE建立连接的时间大于预设关联门限。
负荷大于预设负荷门限的AP的AP信息，可用于表明AP的当前负荷是否大于的预设负荷门限，一般若大于预设负荷门限，表明AP当前负荷过大。
所述用户设备在AP之间的切换频次信息，可用于表明UE在每个AP之间的切换频率，以及在哪些AP之间进行切换。
所述第二辅助信息包括以下至少其中之一：
AP位置信息；
AP之间的相邻关系信息；
初始AP组的信息；
不可用AP的AP信息；
能够扫描但是关联不到AP的AP信息；
AP的关联时间信息；
AP的负荷状况信息；
关联时间大于预设关联门限的AP信息；
负荷大于预设负荷门限的AP信息；
AP的网元连接信息；
所述用户设备在AP之间的切换频次信息。
AP位置信息包括AP设置的位置；AP设置的位置，能够决定AP发送的WLAN信号的覆盖范围等。
AP之间的相邻关系信息，表明了哪些AP是相邻设置的AP，通过相邻关系可方便UE在不同AP之前的切换。
初始AP组的信息，表明初始哪些AP是归属于同一AP组，这些AP组的属性参数。例如有些AP组暂时设置禁止接入等参数。
不可用AP的AP信息，表明有哪些AP组是不可用的。例如有些AP组因为AP的退出、AP的故障等原因导致AP组不可用，这样的话，需要及时更新AP组，方便后续UE的AP切换和LTE网络负荷的均衡以及AP切换的控制。本申请中AP切换包括UE与一个AP建立有连接，切换到与另一个AP建立连接。
所述AP的网元连接信息，表明所述AP连接了哪些WLAN网元，例如AP是通过其内部的WT与LTE网络连接，还是通过外部WT与LTE网络建立连接，AP连接了哪些WLAN路由或接入(Access Controller，AC)设备等信息。这样的话，方便eNB进行AP组的划分，例如将连接到同一WT上的AP划分到同一AP组或控制同一个AP组内的所有AP都是连接到同一WT上的AP。
在本实施例所述步骤S112中具体如何进行所述AP分组，可包括如下：
所述基于所述辅助信息，按照分组策略进行AP分组形成AP组，包括以下至少其中之一：
同一AP组的N个AP的覆盖区域连续分布；所述N为不小于1的整数；
同一AP组的AP连接在相同的WT上；
不同的AP组包括的AP不同。
在本实施例中归属到同一AP组的2个或3个AP的覆盖区域是相同的， 这样的话，才能够保证UE在同一个AP组内的AP之间实现更好的切换。若归属于通过一AP组的两个AP的覆盖区域之前形成有覆盖盲点地带，这样的话，当UE位于该覆盖盲点地带时，无法与该AP组内任何一个AP连接，也无法切换到任何一个AP，会导致WLAN服务的中断，若UE此时需要进行数据传输，就不得不通过LTE网络来进行，显然这样会导致网络服务效果的降低。
同一AP组的AP连接在相同的WT上。这样的话，若一个AP组的信息需要通过WT上报，进行通过一个WT上报即可，LTE通过WT下发控制信息控制该AP组，也仅需通过该WT下发控制信息即可，信息传输和网络控制更为简便。
不同的AP组包括的AP不同，可认为任意两个AP组包括的AP均不同，实质上一个AP仅能归属到一个AP组。若一个AP位于两个AP组的情况，这两个AP组的组参数不同时，可能会导致该AP出现参数设置和功能实现的冲突，从而导致不稳定或故障状态。
作为本实施例的进一步改进，所述步骤S112还包括：
将跨组切换频次大于第一预设频次的AP组进行合并；
调整处理跨组切换频次大于第二预设频次的AP所在的AP组。
所述跨组切换频次可为基于所述用户设备在AP之间的切换频次信息确定的参数，也可以是包含在所述第一辅助信息或所述第二辅助信息中的信息。
例如，包括AP组1和AP组2；UE在AP组1和AP组2之间的跨组切换非常频繁，以致于所述跨组切换频次大于第一预设频次时，将这两个AP组合并成一个新的AP组。这样的话，UE可以在新的AP组内的每个AP之间更加自由的切换；避免频繁请求LTE网络的网元(如eNB)进行跨组切换的判决。
例如，AP组1包括AP1、AP2和AP3；AP1高频率的接收从AP组2切换过来的UE，也高频率的处理从AP组1切换到AP组2的UE离开。这个时候，为了更好的实现UE在AP1与AP组2内的AP之间的切换，可以将AP1调整到AP组2中。调整后，AP组2中将增加AP1，而AP组1将删除 AP1，仅剩下AP2和AP3。
作为本实施例的再次改进，所述步骤S112还包括：
将负荷高于指定负荷门限的AP或AP组重新进行AP分组，更新AP组。
本所述步骤S112中可以根据前述的AP的负荷状况信息，确定单个AP的负荷，也可以确定出整个AP组的负荷。
例如，当一个AP组内的负荷过多时，通过AP组的调整，引入当前负荷较低的AP，实现负荷均衡。当某一个AP的负荷过高，高于所述指定负荷门限时，可以将其加入负荷较低的AP组中，同样通过UE的AP切换也能快速的负荷的均衡。
所述步骤S112还包括以下至少其中之一：
基于第一优先策略，优先根据所述第一辅助信息进行所述AP分组；
基于第二优先策略，优先根据所述第二辅助信息进行所述AP分组。
当执行主体eNB或WT同时获取到了所述第一辅助信息和第二辅助信息；了所述第一辅助信息和所述第二辅助信息可能存储在一些重叠的信息，具体以哪个信息作为进行所述AP分组的依据信息。在实施例中依据优先策略来决定。故在本实施例中可基于第一优先策略，优先根据第一辅助信息进行AP分组，也可以基于第二优先策略优先根据所述第二辅助信息进行AP分组。
这里的优先根据第一辅助信息进行AP分组可包括以下的任意一种：仅基于第一辅助信息进行AP分组；基于第一辅助信息和第一辅助信息中没有但是第二辅助信息确有的信息进行分组；当第一辅助信息和第二辅助信息都提供了对同一参数的上报信息，在计算估算值时，可以使第一辅助信息的上报参数对应有更大的权值。
这里的优先根据第二辅助信息进行AP分组可包括以下的任意一种：仅基于第二辅助信息进行AP分组；基于第二辅助信息和第二辅助信息中没有但是第一辅助信息确有的信息进行分组；当第二辅助信息和第一辅助信息都提供了对同一参数的上报信息，在计算估算值时，可以使第二辅助信息的上报参数对应有更大的权值。
当然在具体实现时，不局限于上述方法。
当然，所述步骤S120还可基于第一辅助信息和第二辅助信息的信息交集来进行所述AP分组。信息交集即为所述第一辅助信息和所述第二辅助信息都有的信息，且该信息在所述第一辅助信息和所述第二辅助信息的具体信息内容相差小于指定阈值时，确定该消息属于所述信息交集内的信息。例如，UE上报的第一辅助信息包括AP1的关联时间为1秒，WT上报的第二辅助信息包括AP1的关联时间为1.01秒。首先第一辅助信息和第二辅助信息都包括所述AP1的关联时间，且这个关联时间的差异值为0.01秒，小于所述指定阈值；这时可认为所述第一辅助信息和第二辅助信息的信息交集包括所述AP1的关联时间。
所述方法还包括：基于所述辅助信息，设置所述AP组的属性参数。
在本实施例中还设置所述AP组的属性参数。这里的AP组的属性参数包括对整个AP组内的所有AP都有效的参数；例如设置AP组是否暂时禁止接入和切换等参数。
通过所述AP组的属性参数的设置，可以控制所述AP组的工作状态及间接控制AP的切换。
在具体的实现过程中，执行主体如eNB可自动向所述UE或WT发送辅助信息的获取请求；并接收UE或WT基于所述获取请求返回的所述第一辅助信息或所述第二辅助信息。
在执行完上述步骤S112之后，就确定了AP组，从而也就确定了AP组的信息；AP组的信息通常包括AP组的标识信息、AP的个数、每个AP的AP信息。所述AP组的标识信息可包括组号等信息。
值得注意的是：在第二种方式中，所述eNB基于所述辅助信息进行AP分组，形成AP组并最终基于AP组形成AP组信息的方法，也适用于WLAN的网元形成所述AP组信息的技术方案中，例如，WT也获取所述辅助信息，所述辅助信息同样可包括第一辅助信息和第二辅助信息，并基于所述辅助信息进行AP分组，AP分组形成AP组后形成所述AP组信息；不同的是，所述WT在形成所述AP组信息之后将发送给所述eNB。
当然在第二种方式中，由于是由eNB进行AP组的分组的，为了方便WLAN的管理和控制，在本实施例中所述eNB还会将AP组信息通过Xw接口发送给WT。
在本实施例的第一种方式中，若WLAN网络的网元来进行AP分组，并形成所述AP组信息的话，则所述方法还包括：接收所述用户设备发送的第一辅助信息；将所述第一辅助信息通过Xw接口发送给所述WT；所述第一辅助信息用于所述WT形成所述AP组信息。在本实施例中为了避免修改所述WLAN的通信协议，减少修改WLAN的通信协议导致的各种困难，在本实施例中所述UE通过eNB向所述WT发送所述第一辅助信息。
作为本实施例的进一步改进，所述步骤S120可包括：将所述AP组信息承载在无线资源连接RRC重配置消息中发送给所述用户设备。
所述eNB可以通过其他任意消息向所述UE发送所述AP组信息，例如，增加一个专用信令来传输所述AP组信息，但是在本实施例为了减少eNB和UE之间的信息交互次数，从而降低UE的功耗，同时也为了简化所述AP组信息的传输，在本实施例中所述eNB会将所述AP组信息承载在无线资源连接(Radio Resource Connection，RRC)重配置消息中发送给所述UE，这样的话，用户设备在接收到所述RRC重配置消息时，就接收到了所述AP组信息。
在RRC重配置消息中包括各种消息，在本实施例中方便UE从RRC重配置消息快速解析出所述AP组信息，在本实施例中，所述步骤S120包括：将所述AP组信息承载在RRC中的测量配置信息中发送给所述用户设备；或将所述AP组信息承载在RRC中的紧耦合配置信息中发送给所述用户设备。
总之，本实施例提供了一种AP组信息处理方法，包括了AP组信息的交互方法，不管AP组信息的形成执行主体是eNB还是WLAN的网元，都通过eNB向UE发送所述AP组信息，实现了AP组信息的简单交互，以保证WLAN和LTE网络的紧耦合。
本发明实施例还提供了一种计算机存储介质，所述计算机存储介质中存 储有计算机可执行指令，所述计算机可执行指令用于执行上述方法。

当所述获取单元110的结构为结构二时，所述eNB还包括第二通信单元，设置为将所述AP组信息发送给WT，方便WT进行AP进行管理和控制；在具体实现时，所述eNB也可以不用向所述WT发送所述AP组信息。
当所述获取单元110的结构为所述结构一时，所述第一通信单元120，还设置为接收所述用户设备发送的第一辅助信息；所述eNB还包括：第二通信单元，设置为将所述第一辅助信息通过Xw接口发送给所述WT；所述第一辅助信息用于所述WT形成所述AP组信息。
为了不修改所述WLAN的通信协议，以免导致WLAN在传输第一辅助信息的困难，在本实施例中由所述eNB接收UE发送的第一辅助信息，并将第一辅助信息发送给WT，这样简便的实现了形成所述AP组信息过程中，UE与eNB之间的第一辅助信息的交互。
此外，所述第一通信单元120，还设置为将所述AP组信息承载在无线资源连接RRC重配置消息中发送给所述用户设备。
在本实施例中为了减少所述eNB和UE之间的信息交互次数，降低所述UE的功耗，在本实施例中所述第一通信单元120会将AP组信息承载在所述RRC重配置消息中发送给UE。
可选地，所述第一通信单元120，是设置为将所述AP组信息承载在测量配置信息中发送给所述用户设备；或将所述AP组信息承载在紧耦合配置信息中发送给所述用户设备。
总之，本实施例所述的eNB将会用于将所述AP组信息发送给UE，可为实现前述方法实施例的硬件设备，避免AP组信息通过WLAN的网元下发给UE导致的通信难度大等问题。
以下结合上述任意一个实施例，提供几个具体示例：
示例一：
本示例提供一种进行AP组信息处理方法，本实施例中所述的AP组信息为AP组的相关信息。该方法包括AP组划分和确定AP组信息。
如图5所示，本示例所述方法包括：
步骤S11：eNB通过配置方法确定AP组信息。
所述AP组信息包含如下内容：
-组号
-AP组包括的AP的个数
-每个AP的信息：BSSID,SSID,MAC，频点等。
在这个实施例中AP组信息表明包括3个AP组，且具体如下：
-AP组1：AP1、AP2及AP3；
-AP组2：AP4,AP5,
-AP组3：AP6。
步骤S12：eNB向WT发送包括AP组信息的Xw信令；具体可如：将AP组的信息通过Xw的控制面协议接口告知WT。
步骤S13：eNB通过空口下行消息信元告知终端AP组的信息；具体如，向UE发送包括AP组信息的RRC重配置消息。
所述空口下行消息信元可以为如下之一：
1)RRC重配置消息中的测量配置信息信元，这里的测量配置信息信元为用于承载所述测量重配置信息的字段，还能够用于承载所述AP组信息。
2)RRC重配置消息中的紧耦合配置信息信元，这里的紧耦合配置信息信元为用于承载前述紧耦合配置信息的字段，还能够用于承载所述AP组信息。
示例二：
如图6所示，本示例所述的方法包括：
步骤S21：WT通过配置方法确定AP组信息。通常WT将基于AP组确定出所述AP组信息，一般情况下，所述AP组也可以是由所述WT通过AP 分组确定的。
步骤S22：eNB接收包括所述AP组信息的Xw信令。
步骤S23：eNB向UE发送包括AP组信息的RRC重配置消息。
以下介绍一下：WT通过一定方式确定AP组信息的方法：
方式一：WLAN的网元通过内部配置方法确定AP组的信息，比如设定3个AP组：AP组1、AP组2及AP组3。AP组1包括AP1、AP2及AP3；AP组2包括AP4及AP5；AP组3包括AP6。
方式二：WT动态获取WLAN中与其相连的AP的相关信息，通过邻接关系构成一个AP组或者N个AP组，所述N为不小于2的整数。
步骤S22：eNB接收包括AP组信息的Xw信令。其中，WT将AP组信息通过Xw的控制面协议接口告知eNB。
步骤S23：eNB向UE发送包括AP组信息的RRC重配置消息。
示例三：
如图7所示，在本示例所述方法包括：
S31：WT通过配置方法确定AP组初始信息，这里包括基于AP初始分组确定出所述AP组初始信息。
步骤S32：eNB接收包括AP组初始信息的Xw信令；
步骤S33：eNB确定AP组并形成新的AP组信息。在本步骤中，eNB将基于AP组初始信息及且前述的辅助信息，重新进行AP分组，并形成所述AP组信息。
步骤S34：eNB向WT发送包括新的AP组信息的Xw信令。
在具体实现时，所述eNB还会向UE发送所述AP组信息。
例如，WT决定AP组初始信息，比如设定3个AP组：AP组1，AP组2，AP组3。AP组1包括AP1、AP2及AP3。AP组2包括AP4及AP5。AP组3包括AP6。WT网元通过Xw的控制面协议接口告知3GPP系统接入网侧网元AP组初始信息。eNB通过一定方式进一步重新进行AP分组，并形成新的AP组信息。
所述一定方式比如通过终端上报发现AP的异常，比如AP组2的两个AP终端总是无法关联上或者关联失败次数大于某个门限值，故进一步确定AP组信息为两个组：AP组1和AP组3。
在本示例中所述步骤S34和向UE发送所述AP组信息没有一定的先后顺序，可以是先执行步骤S34，再向UE发送所述AP组信息，也可以是先向UE发送所述AP组信息，再执行所述步骤S34。
示例四：
如图8所示，本示例包括：
步骤S41：eNB通过配置方法确定AP组初始信息，本示例中的AP组初始信息与前一示例中的AP组初始信息一致。
步骤S42：向WT发送包括AP组初始信息的Xw信令。
步骤S43：WT更新AP组，确定新的AP组信息；WT基于所述AP组初始信息更新所述AP组。
步骤S44：接收包括新的AP组信息的Xw信令，此处的Xw信令是由WT向eNB发送的。
在具体实现时，所述eNB还会将所述AP组信息发送给UE；如eNB解析所述Xw信令，提取所述Xw信令中的AP组信息，将所述AP组信息承载在下行空口中发送给UE；而WT本身并不通过WLAN向UE发送所述AP组信息。
例如，eNB决定AP组的初始信息，比如设定3个AP组：AP组1、AP组2及AP组3。AP组1包括AP1、AP2及AP3；AP组2包括AP4及AP5；AP组3包括AP6。
eNB通过Xw的控制面协议接口告知wlan系统网元AP组初始信息。
WT通过一定方式进一步确定AP组的信息；
所述一定方式为发现不可用的AP，比如发现AP组2的两个AP不可用，故进一步重新进行AP分组，基于重新AP分组的结果，形成新的AP组包括两AP个组：AP组1和AP组3；基于新的AP组形成AP组信息，
WT并过Xw的控制面协议接口告知eNB网元。
