技术领域
本公开涉及无线通信技术领域，具体涉及一种网络接入点(AP，Access Point)动态组网方法及设备。
背景技术
随着异构网络(HetNet，Heterogeneous Network)，超密集网络(UDN，Ultra Dense Network)，以及D2D(Device to Device communication)等通信模式的出现，网络架构将传统蜂窝网单层覆盖模式增强为多层覆盖，小区覆盖的半径越来越小，小区间干扰和移动性面临越来越大的挑战。Ring&Young最早提出蜂窝网的概念。在传统的蜂窝系统中，每个基站受发射功率的限制，只能覆盖有限的区域，被称为小区。基站是该小区的控制和数据中心，负责覆盖范围内的无线资源管理、信号处理和移动性管理等。由于小区间干扰和覆盖黑洞的存在，这种网络部署形式无法提供良好的性能。分布式天线系统(DAS)、协作多点传输(CoMP)以多个站点之间集中式或协作式的处理方式，开始改变以单个基站为管理中心的蜂窝概念。Greentouch定义的超蜂窝架构(BCG)和3GPP定义的双连接将站点的信令与数据分离，以及为了更好的在异构网下实现流量卸载的上下行解耦，进一步突破传统蜂窝概念。
移动网络使得在线视频流，视频会议，交互游戏等业务得到大量部署，产生大量网络流量，尤其是在城市密集区和热点区域，移动通信网络面临流量激增的问题。目前解决流量激增问题的有效方案是通过减小小区覆盖面积，增加小区部署量来增加频率的复用以及实现容量的扩张。3GPP通过部署femtocell， picocell，microcell增加网络容量，实现流量卸载，小小区增强技术是3GPP的一大特色，METIS提出了超密集网络的概念，并研究了上下文信息来优化用户设备(UE)接入点选择，分析了小区簇为UE提供服务，通过减少不必要的切换以及减少小面积进行的切换来提高移动效率。
当前为用户提供数据服务，主要是以网络为中心，UE要感知网络环境及通过信号的感知触发切换操作。而网络密集化的部署，多无线接入技术(Multi Radio Access Technology，Multi-RAT)下接入点类型繁多且覆盖面积减小，接入点动态变化，使得UE即使在低速移动甚至静止的情况下都要进行频繁的切换，UE要时刻感知网络环境进行切换，严重影响了用户体验，且频繁的切换会对核心网络造成信令负载的问题。
当前的小区簇机制主要解决的问题是资源调度分配问题，小区簇大多是预先定义的。使用小区簇为UE提供服务，可有效减少UE切换的次数。在超密集网络中，接入点(AP)的接入是动态的，会根据网络的负载能力及节能需求进行调整；UE可以作为接入点为其他UE提供服务；用户需求的多样性导致UE所需要的带宽不同，需要多层网络进行协作为UE提供服务。这样静态的小区簇不能动态的将新接入的AP加入到服务列表中，不利于为UE提供连续的服务，且在传统网络中的小区簇机制不利于不同RAT间的协作，自然不能满足未来网络系统为UE提供最优业务体验的要求。

具体实施方式
为使本公开技术方案和优点更加清楚，下面将结合附图及具体实施例进行详细描述。
移动通信已经深刻地改变了人们的生活，在移动通信网络中，移动数据流量的激增与各种新业务和新应用场景的不断涌现，大量不可预计的用户终端同时接入网络，很多用户终端聚集于覆盖有限的区域。随着5G技术的发展，超密集网络通过在蜂窝网的热点地区增加低功率基站的部署密度，以提升系统容量和网络覆盖，降低时延及能源消耗。
传统网络以网络为中心，许多功能，诸如服务控制和移动控制在较高层集中，包括移动性管理实体(MME)，公共数据网络网关/服务网关(P-GW/S-GW)。UE的切换以及位置管理等业务都需要访问MME等居于核心网络的功能模块，造成网络信令负载重和数据冗余传输。面对UDN中Multi-RAT，多AP的场景，用户面和控制面的紧耦合将使UE频繁切换，移动性管理、网络资源管理和干扰管理的复杂性显著提升。
针对UE在UDN中频繁感知接入环境、频繁切换影响用户体验，网络负载均衡问题以及静态规划小区簇无法满足网络接入点动态变化的问题，本公开实施例将以UE为中心的设计方法引入移动网络，提出了一种以UE为中心的网络 接入点动态组网方法，可以依据UE需求和网络状态选择合适的AP组(APG，AP Group)提供服务，减少UE对网络环境的频繁感知，在用户移动过程中通过APG的动态组织与协同工作，保证用户业务传输的连续性。
本公开实施例提出一种以UE为中心的网络接入点动态组网方法(DAPGing，Dynamic AP Grouping)，应用于UDN中，实现以UE为中心的接入点组网。UDN中设置有基于不同RAT的AP，UE基于自身的接入能力可以接入对应的AP，获得数据传输服务。
本公开实施例采用用户面与控制面分离的思想，通过控制面更新APG中AP的组成，按UE需求提供相应的网络接入和通信能力。APG采用虚拟连接向UE提供服务，通过多点协助传输方式，由APG中的一个或多个AP为UE提供数据传输服务。下面首先介绍一下本公开实施例中涉及的部分概念。
APG：由网络动态感知UE周围无线接入点的集合。APG是UDN中管理区域内无线接入点为UE提供服务的逻辑结构，可以通过一组AP为UE提供服务。为了提供以UE为中心的服务，在DAPGing中，APG会跟随UE提供网络接入服务，随着UE的移动以及根据网络接入点的情况，接入端控制器会动态地更新AP列表。
网络服务中心设备(NSC，Network Service Center)：居于核心网络边缘的控制设备，在网络端提供控制和传输功能。NSC可以是物理的实体设备，也可以是逻辑设备，如设置于其他实体设备中的逻辑模块。
核心网侧可以设置一个或多个NSC，各个NSC对其管理范围的本地服务中心设备(LSC，Local Service Center)进行管理。本公开实施例中，可以预先在各个NSC上配置其管理范围内的LSC，每个LSC均与其归属的NSC之间建立有通信连接。
本公开一些实施例中，各个UE的APG是由NSC为这些UE分配的，且在该NSC管理范围内是与这些UE是一一对应的。因此，APG可以用APG标识(APG ID)来指示，同一NSC下的APG的ID各不相同。NSC维护由其所分配的APG与UE之间的对应关系。
LSC：居于接入网侧的控制设备，在无线接入端提供控制面和用户面分 离，所有类型AP都要回程到LSC。LSC可以是物理的实体设备，也可以是逻辑设备，如设置于其他实体设备中的逻辑模块。
对于UE来说，LSC可以分为服务LSC和非服务LSC，通常某个UE的服务LSC只有一个，非服务LSC可以有1个或多个。服务LSC上维护有该UE对应的APG的相关信息，例如APG ID以及APG中的成员AP，还可以维护有该UE对应的LSC的相关信息，例如该UE的服务LSC和非服务LSC，也可以维护该UE在各个LSC下的成员AP等信息。接入网侧可以设置有多个LSC，各个LSC对其管理范围的AP进行管理，每个AP均与其归属的LSC之间建立有通信连接。本公开实施例中，可以预先在各个LSC上配置其管理范围内的AP，也可以由AP在启动后，通过自动发现过程，寻找到合适的(如时延最小、带宽最大)的LSC，并注册到该LSC下，成为其管理范围内的一员。
另外，接入网侧的各个LSC之间可以建立有通信链路，实现相关信息的传输与同步。考虑到链路的成本，在LSC数量较少时，任意两个LSC之间可以直接连接，从而建立LSC之间的星形拓扑连接；在LSC数量较多时，可以仅建立LSC与其归属的NSC之间的连接，同一NSC下的各个LSC可以通过该NSC实现信息的转发与同步。当然，也可以同时建立同一NSC下的LSC之间的直接连接以及LSC与其归属的NSC之间的通信连接。
DAPGing：由网络动态感知UE周围无线环境，动态组成该UE的APG，以UE为中心提供网络传输服务的机制。基于用户面与控制面分离的架构实现的DAPGing，在网络端由NSC进行管理，在接入网端由LSC进行管理。通过网络端与用户端的分布式管理，优化对UE传输服务的性能。网络在接入网端可以收集UE周围的无线环境，管理APG，对相应的AP进行信息配置，网络端确保UE的APG的唯一性，接入网端设备由网络端设备进行管理协作，通过网络的管理，实现对APG进行初始化，APG成员更新，APG间切换，以及APG撤销等的相关功能。
UE：是指用户侧的终端设备，例如具有屏幕(或者说，显示单元)的终端设备，具体可以是手机、平板电脑以及带显示单元的计算设备、信息显示设备、图像拍摄设备或通信设备等。以手机为例，手机可以包括射频(RF，Radio  Frequency)电路、存储器、输入单元、无线保真(WiFi，wireless fidelity)模块、显示单元、传感器、音频电路、处理器、以及电源等部件。本领域技术人员可以理解，以上给出的手机结构仅为示例而非限定，手机还可以包括比图示更多或更少的部件，或者组合某些部件，或者不同的部件布置。另外，根据接入网的不同标准/属性，UE可以具有对应的一个或多个接入单元，以发现接入网络并实现网络接入功能。例如，手机可以具有WIFI接入功能、3G、4G、LTE网络接入功能、各种微蜂窝网络接入功能等。
以下实施例将从LSC侧说明本公开实施例的接入点动态组网方法。
请参照图1，本公开一些实施例提供的网络接入点动态组网方法，应用于一UDN中，包括以下步骤：
步骤101，接入网侧的第一LSC，接收第一AP在发现自身能够服务的第一UE后发送的第一通知消息，该第一AP是归属于第一LSC的一个AP。
这里，第一AP在其覆盖范围内发现第一UE后，根据自身的服务能力(如网络接入能力、自身负载状态等)以及UE的设备能力(如UE的网络接入能力等)，判断出第一AP可以为第一UE提供服务时，向第一AP归属的第一LSC发送上述第一通知消息。该第一通知消息可以携带有第一AP和第一UE的信息，如第一AP和第一UE的标识等信息。
步骤102，在第一LSC记录有第一UE的服务LSC的信息时，根据该信息判断第一LSC是否是该第一UE的服务LSC，其中，该第一UE的服务LSC上维护有该第一UE对应的第一APG以及该第一UE对应的LSC的信息，第一APG中包括有当前能够服务该第一UE的成员AP，第一UE对应的LSC中包括有各个成员AP归属的LSC。
这里，第一LSC在接收到上述第一通知消息后，判断自身是否维护有第一UE的服务LSC的信息，若维护有该信息，则根据该信息判断第一LSC是否为第一UE的服务LSC。
步骤103，第一LSC在判断出自身是第一UE的服务LSC时，将第一AP加入到该第一UE对应的第一APG中，并向第一APG中的各个成员AP发送第一APG的更新消息，该更新消息携带有第一APG的成员AP的信息，以使接收到该更 新消息的AP据此更新第一APG中的成员AP。
本公开实施例上述方法，第一AP在新发现第一UE且第一AP能为该第一UE提供服务时，将向第一LSC发送第一通知消息，该第一通知消息携带有第一UE和第一AP的信息。这样，第一LSC在自身作为第一UE的服务LSC，且已经为第一UE分配了APG(第一APG)时，将更新第一APG的成员AP，并将第一APG的更新消息通知给第一APG中的各个成员，由此实现了APG的成员更新。更新后的APG中的成员，可以通过多点传输传输方式，由一个AP或多个AP为UE提供数据传输服务。基于以上步骤，本公开实施例实现了以用户为中心，动态更新为用户服务的接入点组合，可以减少用户对网络环境的频繁感知，降低核心网的信令负载。
上述步骤103中，第一LSC需要向第一APG中的各个成员AP发送第一APG的更新消息，由于各个成员AP归属的LSC可能不同，因此，上述APG更新消息的发送，具体可以包括：确定第一UE对应的LSC中除服务LSC外的非服务LSC，并通过该非服务LSC向所述第一APG中归属于该非服务LSC的各个成员AP，转发所述更新消息；以及，向所述第一APG中归属于服务LSC的各个成员AP，直接发送所述更新消息。也就是说，对于归属于服务LSC的成员AP，服务LSC可以直接向该AP发送上述APG更新消息；对于归属于非服务LSC的成员AP，服务LSC可以将上述更新消息发送给非服务LSC，由非服务LSC转发给成员AP。
如图2所示，上述步骤102中，在第一LSC记录有第一UE的服务LSC的信息时，如果第一LSC根据该信息判断出自身不是该第一UE的服务LSC，则所述方法还包括以下步骤：
步骤104，第一LSC向第一UE的服务LSC发送用于请求将第一AP加入到第一APG的第一请求消息。
这里，第一LSC根据本地维护的第一UE的服务LSC的信息，确定第一UE当前的服务LSC，并向该服务LSC发送上述第一请求消息，第一请求消息可以携带第一AP、第一UE以及第一LSC的信息。
步骤105，第一LSC接收服务LSC在将第一AP加入到第一APG，以及根据 第一LSC更新第一UE对应的LSC后发送的第一APG的更新消息，并向所述成员AP中归属于第一LSC的各个AP，转发该APG更新消息。
本公开实施例中，服务LSC在收到上述第一请求消息后，可以根据其中携带的第一AP、第一UE以及第一LSC的信息，将第一AP加入到第一UE对应的第一APG中，并根据第一LSC更新第一UE对应的LSC，具体的，上述更新的方式包括：如果第一LSC已存在于第一UE对应的LSC，则不需要执行任何动作；如果第一LSC未存在于第一UE对应的LSC中，则需要将第一LSC添加到第一UE对应的第一LSC中。
由于第一APG中新增加了成员AP(第一AP)，因此服务LSC需要向第一APG中的各个成员AP发送第一APG的更新消息。具体的，对于归属于服务LSC的成员AP，服务LSC可以直接向该AP发送上述APG更新消息；对于归属于非服务LSC的成员AP，服务LSC可以将上述更新消息发送给非服务LSC，由非服务LSC转发给成员AP。于是，本公开实施例中，第一LSC在上述步骤105中，可以接收服务LSC发送的第一APG的更新消息，然后将该消息转发给处于其管理范围内的第一APG的成员AP，使得各个成员AP可以据此更新第一APG中的成员AP。
以上介绍了第一LSC在本地维护有第一UE对应的服务LSC的信息时，如何处理第一通知消息。本公开实施例中，在第一UE对应的第一APG初始化完成前，或者在第一LSC管理范围内AP都加入到第一UE对应的APG之前，第一LSC本地可能并没有任何关于第一UE对应的服务LSC的记录。此时，如图3所示，本公开一些实施例的网络接入网点动态组网方法，在上述步骤101之后，还包括以下步骤：
步骤106，在第一LSC未记录第一UE的服务LSC的信息时，第一LSC向核心网侧的NSC发送用于查询第一UE的服务LSC的查询消息，第一LSC归属于该NSC。
在本地未维护第一UE的服务LSC时，第一LSC需要向其归属的NSC发送查询消息，用以查询第一UE的服务LSC。该查询消息可以携带第一UE、以及第一LSC的信息，用以标识对应的设备。该查询消息还可以携带第一AP的信息。
步骤107，如果第一LSC接收NSC在未查询到第一UE的服务LSC后返回的、用于指示配置第一LSC为第一UE的服务LSC的第一配置消息，该第一配置消息携带有NSC新分配的唯一对应于第一UE的APG，则根据该第一配置消息，在本地记录自身为第一UE的服务LSC的信息，建立并维护第一UE对应的第一APG以及该第一UE对应的LSC的信息，其中，第一UE对应的LSC包括作为服务LSC的第一LSC，第一APG包括有第一AP；并向第一APG中的各个成员AP发送第一APG的更新消息。
这里，NSC根据所述查询消息，查询是否已为第一UE分配了对应的APG，若未分配，则通过APG初始化流程，为第一UE分配一个APG，并向第一LSC发送第一配置消息，用以将首个上报该第一UE的第一LSC配置为该第一UE的服务LSC。第一LSC在建立并维护第一UE对应的第一APG之后，需要将第一APG的成员AP发送APG更新消息，具体的发送方式可以包括：通过第一UE的该非服务LSC向所述第一APG中归属于该非服务LSC的各个成员AP，转发所述更新消息；以及，向所述第一APG中归属于服务LSC(第一LSC)的各个成员AP，直接发送所述更新消息。
步骤108，如果第一LSC接收NSC在查询到第一UE的服务LSC后返回的、用于指示第一UE的服务LSC的第二通知消息，则根据该第二通知消息，在本地记录第一UE的服务LSC的信息；以及，接收服务LSC向发送的第一APG的更新消息，并向所述第一APG中归属于第一LSC的各个成员AP，转发该APG更新消息。
这里，NSC根据所述查询消息，若查询到已为第一UE分配了对应的APG，并建立了第一UE对应的服务LSC的信息，则需要将服务LSC的信息通知第一LSC，并且还可以将该查询消息转发给服务LSC。这样，服务LSC可以根据该查询消息，将第一AP加入到该第一APG中，并将第二LSC加入到第一UE对应的LSC中，然后向第一APG中的各个成员AP发送APG更新消息。对于归属于非服务LSC的成员AP，服务LSC通过非服务LSC向该成员AP转发该APG更新消息。于是，在上述步骤108中，第一LSC可以接收到服务LSC发送的APG成员消息，并转发给归属于第一LSC的成员AP，以使AP更新第一APG中的成员AP。
以上实施例说明了在第一LSC处记录或未记录有第一UE的服务LSC的信息时，如何对接收到第一AP发送的第一通知消息进行处理，以在第一UE对应的第一APG中增加成员AP。APG的更新，除了增加成员AP，还包括删除成员AP。在将第一AP加入到第一APG之后，本公开实施例还可能将第一LSC管理范围内的第一AP从第一APG中删除，下面将对本公开实施例是如何在第一APG中删除第一AP进行说明。
请参考图4，本公开一些实施例的网络接入点动态组网方法，还包括以下步骤：
步骤41，第一LSC接收第一AP在确定自身将停止为第一UE服务时发送的、用于请求将第一AP从第一APG中删除的第二请求消息。
这里，由于第一UE离开第一AP的覆盖范围，或者第一UE请求减少为其服务的AP数量、或者第一AP由于自身工作负荷或休眠策略等原因，第一AP将不再为第一UE提供服务。此时，第一AP将向其归属的第一LSC发送上述第二请求消息，以请求将自身从第一APG中删除。
步骤42，第一LSC根据本地记录的第一UE的服务LSC的信息，确定自身是否为第一UE的服务LSC：若是，则进入步骤43，否则进入步骤44。
步骤43，第一LSC根据所述第二请求消息，将第一AP从第一APG中删除，并向第一APG中的各个成员AP发送第一APG的更新消息。
这里，当第一LSC为第一UE的服务LSC时，可以直接对其所维护的第一APG中的第一AP进行删除。第一LSC在将第一AP从第一APG中删除后，还可以进一步判断第一APG中的成员AP数量是否为0：
在第一APG中的成员AP数量为0时，删除本地的第一UE的服务LSC的信息，并删除第一UE对应的第一APG以及该第一UE对应的LSC的信息，向NSC发送用于撤销第一APG的撤销消息；
在第一APG中的成员AP数量不为0时，进一步判断第一APG中是否存在归属于第一LSC的成员AP，若不存在，则删除本地维护的第一UE的服务LSC的信息，并向NSC发送用于请求更换第一UE的服务LSC的第三请求消息，该第 三请求消息携带有第一APG的信息以及第一UE对应的LSC的信息。NSC根据第三请求消息，可以更换第一UE对应的服务LSC，例如，将具有最多成员AP的LSC，配置为新的服务LSC，并向第一UE对应的各个LSC发送更新第一UE的服务LSC的通知消息。
作为另一种实施方式，当判断第一APG中不存在归属于第一LSC的成员AP时，可以由第一LSC来为第一UE选择新的服务LSC，例如，从第一UE的非服务LSC中选择一个LSC，并向该选择的LSC发送用于将自身配置为新的服务LSC的配置消息，该配置消息携带有第一APG的信息以及第一UE对应的LSC的信息，以及将该新的服务LSC的信息通知给NSC，以使NSC更新第一UE对应的服务LSC。
步骤44，第一LSC向服务LSC或NSC转发所述第二请求消息，以及接收服务LSC在将第一AP从第一APG中删除后发送的第一APG的更新消息，并将该更新消息转发至所述第一APG中归属于第一LSC的各个成员AP。
这里，当第一LSC不是第一UE的服务LSC时，可以向服务LSC转发上述第二请求消息，也可以将第二请求消息转发给NSC，再由NSC将该请求消息转发给第一UE的服务LSC。该第二请求消息，用以请求服务LSC将第一AP从第一APG中删除。服务LSC在删除第一APG中的第一AP后，将向第一APG中的各个成员AP发送第一APG的更新消息，以对成员AP进行更新。其中，对于归属于非服务LSC的成员AP，服务LSC是通过该非服务LSC向该成员AP发送上述APG更新消息。
本公开实施例中，第一LSC根据其不同的身份(服务LSC或非服务LSC)，可能接收到不同的消息，执行不同的处理流程。下面对此进行说明。
在第一LSC作为第一UE的服务LSC时，第一LSC可能接收到非服务LSC或者NSC转发的请求在第一UE对应的第一APG中增删某个成员AP的请求消息。此时，如图5所示，在增加成员AP时，本公开一些实施例组网方法还包括有以下步骤：
步骤51，作为第一UE的服务LSC的第一LSC，接收NSC或第二LSC向服务LSC发送的用于请求将归属于第二LSC的第二AP加入到第一APG的第四请求 消息；
步骤52，第一LSC将第二AP加入到该第一APG，以及根据第二LSC更新第一UE对应的LSC，并向第一APG中的各个成员AP发送第一APG的更新消息。
这里，上述步骤52中，需要根据第二LSC更新本地维护的第一UE对应的LSC，具体的，如果第二LSC已存在于第一UE对应的LSC，则不需要执行任何动作；如果第二LSC未存在于第一UE对应的LSC中，则需要将第二LSC添加到本地维护的第一UE对应的第一LSC中。
如图6所示，在删除成员AP时，本公开一些实施例组网方法还包括有以下步骤：
步骤61，作为第一UE的服务LSC的第一LSC，接收NSC或第二LSC向服务LSC发送的用于请求将归属于第二LSC的第二AP从第一APG删除的第五请求消息。
步骤62，将第二AP从第一APG中删除，并向第一APG中的各个成员AP发送第一APG的更新消息。
这里，上述步骤62中，在删除第二AP之后，还可以进一步判断第一APG中是否还存在归属于第二LSC的成员AP，若不存在，则可以将第二LSC从本地维护的第一UE对应的LSC中删除，以更新第一UE对应的LSC。
在第一LSC作为第一UE的非服务LSC时，第一LSC可能接收到NSC发送的用于将第一LSC配置为新的服务LSC的第二配置消息，该第二配置消息携带有第一APG的信息以及第一UE对应的LSC的信息，此时，第一LSC根据所述第二配置消息，将自身配置为第一UE的新的服务LSC，在本地维护第一UE的服务LSC的信息，并建立第一UE对应的第一APG以及该第一UE对应的LSC的信息。又例如，第一LSC还可能接收到NSC发送的用于更新第一UE的服务LSC的第三配置消息时，该第三配置消息携带有新服务LSC的信息，此时第一LSC根据所述第三配置消息，更新本地维护的第一UE的服务LSC的信息。
以上实施例中，服务LSC(如第一LSC)在第一APG中增删成员AP后，需要向第一APG中的各个成员AP发送第一APG的更新消息，具体的发送方式包括：对于归属于非服务LSC的成员AP，服务LSC通过该非服务LSC向该成员AP 转发所述APG更新消息；对于归属于服务LSC的成员AP，服务LSC直接向该成员AP发送所述APG更新消息。
上文通过多个实施例，对本公开的第一LSC在接收到不同消息时的处理流程进行了说明。从以上实施例可以看出，本公开实施例提供的接入点动态组网方法，将传统的以网络为中心的理念转变为以用户为中心理念，为用户提供服务，解放用户要频繁感知网络环境，可以为低速或静止的用户通过AP组提供数据传输服务，并且，在用户移动过程中，可以通过AP组的动态调整与AP组内协作实现用户业务的传输，服务AP的改变，减少用户切换的次数。另外，由于本公开实施例中，AP组内的用户切换不需要通过核心网络，从而可以减小对核心网络的信令负载，并能够根据动态获取的网络情况，实现为用户服务接入点的实时调整。
下文将进一步从NSC侧说明本公开实施例的接入点动态组网方法。
请参考图7，本公开一些实施例提供的接入点动态组网方法，在应用于UDN中的NSC时，包括以下步骤：
步骤71，核心网侧的NSC，接收接入网侧的第一LSC发送的用于查询第一UE的服务LSC的查询消息。
这里，第一LSC管理范围内的第一AP，在发现自身能够服务的第一UE后，向第一LSC发送第一通知消息，该第一AP是归属于第一LSC的一个AP。第一LSC根据该第一通知消息，查询本地是否维护有第一UE的服务LSC的信息，如果未维护，则向第一LSC归属的NSC发送上述查询消息，用以查询NSC是否为第一UE分配了对应的APG。该查询消息可以携带第一UE、以及第一LSC的信息，用以标识对应的设备。该查询消息还可以携带第一AP的信息。
步骤72，NSC根据所述查询消息，判断本地是否维护有第一UE对应的服务LSC的信息。
这里，如果NSC已经为某个UE分配过APG且该APG未被撤销，则将在本地维护该UE、APG以及服务LSC的对应关系。因此，NSC可以根据本地是否维护有第一UE的对应关系，判断是否维护有第一UE的服务LSC的信息。
步骤73，在本地未维护有第一UE对应的服务LSC的信息时，为第一UE分配一与该第一UE一一对应的第一接入点组合APG，将第一LSC配置为第一UE的服务LSC，向第一LSC发送用于指示配置第一LSC为第一UE的服务LSC的第一配置消息，并建立第一UE、第一APG以及服务LSC的对应关系，其中，第一配置消息携带有第一APG的信息。
这里，如果NSC本地没有第一UE的服务LSC的信息，则说明尚未为第一UE分配APG，此时NSC将为第一UE分配一个APG(具体的，用一个APG ID来标识该分配的APG)。并且，NSC还将第一LSC配置为第一UE的服务LSC，然后在本地建立并维护第一UE、第一APG以及服务LSC的对应关系。在同一个NSC管理范围内，各个UE具有不同的APG，即APG与UE之间是一一对应的。NSC还向第一LSC发送上述第一配置消息，以使第一LSC根据该消息，将自身配置为第一UE的服务LSC，并在第一LSC本地建立并维护第一UE对应的第一APG以及该第一UE对应的LSC的信息，其中，第一UE对应的LSC包括作为服务LSC的第一LSC，第一APG包括有第一AP。
步骤74，在本地维护有第一UE对应的服务LSC的信息时，向第一LSC返回第一UE对应的服务LSC的信息。
这里，如果NSC本地存在第一UE的服务LSC的信息，则说明已经为第一UE分配了APG，此时NSC可以根据本地维护的第一UE的对应关系，查询到第一UE对应的服务LSC，并将该服务LSC的信息返回给第一LSC，以使第一LSC能够获得该服务LSC的信息并与服务LSC进行通信，以请求将第一AP加入到第一UE对应的APG中。
本公开实施例通过以上步骤，由NSC统一为其管理范围内的UE分配APG，并配置UE的服务LSC，由服务LSC维护该UE的APG，实现了接入点的动态组网。
上述步骤74中，NSC将第一UE的服务LSC的信息通知给第一LSC，使得后续第一LSC可以向服务LSC发送请求消息，用以请求将第一AP加入到第一UE对应的APG中。作为另外一种实现方式，本公开实施例中，也可以由NSC直接向服务LSC发送上述请求消息。此时本公开实施例在上述步骤74之后，还可以 包括以下步骤：向服务LSC发送用于将第一AP加入第一UE对应的第一APG以及将第一LSC加入到第一UE对应的LSC的第二请求消息。
这样，服务LSC可以根据该第二请求消息，将第一AP加入第一UE对应的第一APG，并将第一LSC加入到第一UE对应的LSC。然后，服务LSC可以向第一APG中的成员AP发送第一APG的更新消息，使得各个成员AP更新第一APG。
本公开一些实施例中，第一UE的服务LSC可以根据需要进行更换，此时上述组网方法还包括以下步骤：
NSC接收第一UE的服务LSC发送的用于请求更换第一UE的服务LSC的第三请求消息时，该第三请求消息携带有第一APG的信息以及第一UE对应的LSC的信息；
NSC根据所述请求，从第一UE对应的LSC中选择第一UE的新服务LSC，并向该新服务LSC发送新服务LSC的第二配置消息，该第二配置消息携带有第一APG的信息以及第一UE对应的LSC的信息，以及向第一UE对应的LSC发送用于第一UE的服务LSC的更新消息时，该更新消息携带有新服务LSC的信息。
这里，新服务LSC的选择，可以从第一UE对应的LSC中，选择具有最多成员AP的LSC，即，第一APG中归属于该LSC的成员AP最多，将该LSC作为新的服务LSC。当然，也可以选择当前为UE提供数据传输服务的成员AP所属的LSC，作为新的LSC。在当前有多个成员AP同时为第一UE提供数据传输服务时，可以选择其中的任意一个成员AP所归属的LSC，作为新的LSC。
本公开一些实施例中，NSC在为第一UE分配了第一APG之后，还可以撤销该第一APG。例如，在第一UE离开该NSC归属的超密集网络的覆盖范围，或者第一UE切换到传统的蜂窝网络，此时可以撤销第一APG。通常，APG的撤销可以由服务LSC发起，因此，上述组网方法还可以包括以下步骤：
NSC接收第一UE的服务LSC发送的用于撤销第一APG的撤销消息；
NSC根据所述撤销消息，回收为所述第一UE分配的所述第一APG，并删除本地维护的第一UE、第一APG以及服务LSC的对应关系。
以上从NSC侧说明了本公开实施例的接入网动态组网方法。下面将进一步 从AP侧进行描述。
请参照图8，本公开一些实施例提供的接入点动态组网方法，在应用于超密集网络中的AP时，包括以下步骤：
步骤81，第一AP在发现自身能够服务的第一UE后，向第一AP归属的第一LSC发送一用于通知发现第一UE的第一通知消息。
步骤82，第一AP接收第一LSC发送的第一APG的第一更新消息，该第一更新消息携带有第一UE对应的第一APG的成员AP的信息，第一APG中包括有当前能够服务该第一UE的成员AP。
这里，第一LSC在收到上述第一通知消息后，可以按照前文实施例中介绍的方式，向第一UE的服务LSC请求将第一AP加入到对应的APG(第一APG)中。最终，在第一AP加入到第一APG后，服务LSC将通过第一LSC向第一AP发送上述第一更新消息。这里，第一LSC可能是第一UE的服务LSC，也可能不是。如果是，则上述第一更新消息是由第一LSC直接发送给第一AP；如果不是，则上述第一更新消息是由服务LSC经过第一LSC转发给第一AP。
步骤83，第一AP根据第一更新消息，在本地维护第一UE对应的第一APG，并与第一APG中的成员AP通过多点协调传输方式为第一UE提供数据传输服务。
在上述步骤83之后，第一AP还可以动态更新接入点组合，此时上述方法还包括：第一AP接收第一LSC发送的第一APG的第二更新消息，所述第二更新消息携带有更新后的第一APG；第一AP根据所述第二更新消息，更新本地维护的第一APG。
第一AP可能由于自身原因(如工作负荷高、休眠周期到达等)或第一UE的原因(如第一UE离开第一AP的覆盖范围内、第一AP与第一UE之间距离过大导致信号质量不满足预定指标等)，将不能再继续为第一UE服务后，此时上述方法还包括：第一AP向第一LSC发送用于请求将第一AP从第一APG中删除的请求消息，并删除本地维护的第一APG。通过该请求消息，将触发第一UE的服务LSC删除第一APG中的第一AP，以更新第一APG。
通过上述步骤，第一AP在本地维护了第一APG的成员AP的信息，实现了 以用户为中心的接入点组网方案，能够动态更新为用户服务的接入点组合，可以减少用户对网络环境的频繁感知，降低核心网的信令负载。
上文中分别从LSC、NSC、和AP角度对本公开实施例的接入点动态组网方法进行了说明。下面将进一步介绍实现上述方法LSC、NSC和AP。

以上分别介绍了本公开实施例的LSC、NSC及AP的结构以及各自实现的方法流程。
请参考图12及表1，本公开实施例的DAPGing的实现功能包括：APG初始化，APG中的成员AP更新(APG Refresh)，NSC间的APG切换(APG Handover)， APG撤销。
其中，APG Refresh包括LSC内的成员更新和LSC间的成员更新，通过改变APG成员，用户终端与AP之间的无线链路可以从一个AP移动至另一个AP。
APG Handover是指NSC间的APG切换，由于每个NSC内部的APG ID都是唯一的，因此用户终端在移动至一个新的NSC后，将获得一个新的APG ID，同时APG成员也将重新组织。
APG撤销包括APG与传统蜂窝网络间的相互切换，即从APG切换至传统蜂窝网络，或者从传统蜂窝网络切换至APG。

表1
为帮助理解本公开的上述实施例，下面将结合DAPGing实现的以上功能，通过具体若干具体场景，说明本公开实施例的组网方法中各个设备之间的消息交互过程。
场景1：APG初始化
请参考图13，当一用户设备(UE1)初次进入到一超密集网络(UDN)的一个AP(AP1)的覆盖范围内(S1301)，即切换到由UDN网络管理的AP1中，AP1获取UE1的信息，确定UE1的设备能力(如UE1具有何种无线接入能力)，并与对应的LSC1交互UE1的信息(S1303)。
接入网端管理AP1的LSC1获取UE1的信息后，发现本地未记录有UE1对应的APG，则向NSC请求获取APG ID(S1303)。NSC根据该请求，对相应用户的APG进行初始化分配APG ID(S1304)，并向LSC1返回该APG的相关信息(S1305)，并将该LSC1配置为UE1的服务LSC。NSC还在本地记录并维护该UE1、APG、以及服务LSC(即LSC1)的对应关系。
然后，LSC1在本地记录自身为UE1的服务LSC，建立并维护该UE1对应的APG以及LSC(S1306)。在初始化时，该UE1对应的APG里仅包括前面发现该UE1的AP1，该UE1对应的LSC里仅包括该LSC1。
然后，LSC1对APG中的成员AP进行配置，发送APG更新消息，更新各个成员AP维护的UE的APG信息，各个成员AP据此更新并维护APG(S1307)。由于初始化时APG中仅包括AP1，因此，可以由LSC直接向AP1发送APG更新消息。
然后，APG中的成员AP可以基于多点协作技术，为UE1提供数据服务(S1308)。具体的，可以采用CoMP等协作技术，此处不再赘述。所述UE1处于所述APG的至少一个成员AP的覆盖范围内。
以上步骤中，由LSC和AP协作自动检测到可以为用户UE提供服务的AP，在接入网端的本地控制设备(LSC)处对相应APG内的服务接入点进行更新，并对各个接入点进行信息配置。由LSC确定动态APG，该APG包含可以为用户UE提供服务的AP。LSC向APG中的成员AP发送针对终端的无线重配置指令，以触发APG中的成员AP采用多点协同传输方式等技术，进行针对所述终端的 数据传输。由于每个UE的APG的标识是由NSC分配的，所以每个UE在UDN环境下的NSC范围内都有唯一一个动态的APG为其提供服务，实现了以APG为单位管理用户数据传输，可以减小接入管理难度。
场景2：APG中成员AP更新
由于UE在UDN覆盖范围内移动，且UE会发生业务以及网络动态调控的变化，如果使用传统方案，容易频繁发生小小区间的切换，这就会造成对核心网络的信令负载过大。本公开实施例中，UE在AP组的覆盖范围内移动时，由该APG组为用户提供服务，扩大了为该UE提供服务的空间范围，且可以利用不同RAT技术的AP为用户提供多种类型的的无线接入服务，减少了核心网信令负载
DAPGing中APG中的服务首先要进行成员AP的选择，通过LSC的控制实现新的成员AP为用户提供数据传输服务。用户移动与网络状况变化会引起APG列表中的成员AP实时更新，为了不影响用户的业务体验，这就需要网络多方实体的协作，实现APG列表对UE的透明更新。这里我们通过NSC管理的区域内，LSC间的协作或NSC的调节实现网络控制的APG的成员AP更新，即APG列表更新。
通过APG列表动态更新实现了服务AP的滑动，网络通过对AP的选择，实现具体的数据传输，两者结合实现了网络跟随用户提供服务。这里，本公开实施例避免了传统切换操作，通过NSC区域内的自解决能力，减少了传统切换过程中需要向核心网络发送的控制信令，降低了核心网络控制的信令开销。
用户在移动过程中不同接入点的服务表现为APG资源分配与APG列表的动态更新，对于用户终端来说只要维持与APG的连接即可。对于APG资源分配，这个根据需要自行设置控制策略，此处不再赘述。下面将对APG列表更新原因和更新过程这两方面进行了说明。
用户的移动以及网络接入点的变化会引起接入网端LSC对用户的APG列表进行更新。对于APG列表更新的原因主要有：
a)APG是针对一个用户建立的AP服务组，当用户所需提供业务发生改变、 实际服务AP发生改变时需要进行列表更新。例如，当UE不需要更多AP为其提供服务时，可进行资源的节约，此时可以减少为其服务的AP数量。
b)由于接入点负载小于一定的阀值，需要相应的休眠机制进行节能，网络对一部分接入点进行了休眠策略，此时一部分接入点进行休眠状态，网络要更新APG内的AP；或者当某个AP的负载超过一定的门限，此时需要减少该AP服务的UE的数量，将该AP从一些APG中删除。
c)网络负载增加，UND对一些处于休眠状态的AP进行了激活，或者设备到设备(D2D)通信的使用，以及某些UE作为接入点为其他用户提供服务，此时要更新APG列表，对新加入的AP进行相应的消息配置。
d)由于UE发生移动，AP组内的AP由于信号的减弱不能为用户提供服务；又例如，一些AP信号增强，可以为用户提供服务，此时AP组要更新可以为用户UE提供服务的AP，对相应的AP进行消息配置。
APG列表的更新，对用户来说是透明实现的。本公开实施例在同一个NSC的管理范围内，主要考虑在一个LSC范围内的APG列表更新、和两个LSC之间的APG列表更新。
假设UE初始服务APG由LSC1管理，LSC1为服务LSC；相邻接入网由LSC2管理。假设有AP1感知到可以为UE1提供服务。
当AP1感知到用户时，首先会向其所属的LSC发送信息，由LSC判断是否能在用户相应的APG中进行列表的更新：如果该LSC是该UE1的服务LSC，则可以有该UE1进行相应的APG列表的更新；否则，由该LSC向更高层的NSC发送查询信息，经过NSC的协作实现与UE1所属的LSC协同合作更新列表，为用户提供服务：
1)在LSC1范围内的APG列表更新：
此时假设AP1所在的管理区域为LSC1，即AP1归属于LSC1。同时，LSC1还是AP1的服务LSC，LSC1本地维护有UE1的服务LSC的信息，并建立有UE1对应的APG、UE1对应的LSC的对应关系，其中，UE1对应的LSC包括有LSC1，UE1对应的APG中仅包括LSC1管理范围内的AP，没有其他LSC管理范围内的AP。
请参考图14所示的在一个LSC范围内的APG更新(加入成员AP)：
由于UE1移动，或者新增AP1或者网络调节激活AP1，导致AP1可以为UE1提供服务。AP1在感知到UE1时，收集UE1的相关信息，如网络接入能力、设备标识等(S1401)，如发现AP1自身能够为AP1服务，则向其归属的LSC1报告新发现的UE1的相关信息(S1402)。
然后，LSC1根据AP1发来的信息，在确定LSC1自身就是UE1的服务LSC时，即可以更新本地维护的UE1的APG列表，在列表中加入AP1(S1403)。然后，LSC1将向更新后的APG列表中的各个成员AP发送APG更新消息，用以进行成员AP的更新配置(S1404)。这里，由于APG中的成员AP都归属于该LSC1，因此LSC1可以直接向该成员AP发送APG更新消息。
然后，更新后的APG中的成员AP可以基于多点协作技术，为UE1提供数据服务(S1405)。
请参考图15所示的在一个LSC范围内的APG更新(删除成员AP)：
当用户移动导致AP1无法感知到用户，或者AP1要进行休眠而无法再为UE1服务，此时AP1向LSC1发送用于请求将AP1从UE1对应的APG中删除的请求消息(S1501)，LSC1收到该请求后，在相应的用户APG列表中删除AP1(S1502)。
然后，LSC1向更新后的APG中的成员AP发送APG更新消息，用以删除APG中的AP1(S1503)。这里，由于APG中的成员AP都归属于该LSC1，因此LSC1可以直接向该成员AP发送APG更新消息。
然后，更新后的APG中的成员AP可以基于多点协作技术，为UE1提供数据服务(S1504)。
2)在不同LSC间的APG更新：
当AP1归属的LSC2，与UE1当前APG内的成员AP归属的LSC1，不是同一个LSC，这就需要相邻两个LSC间协作为用户传输服务。由于涉及到多个LSC，因此需要由一个LSC作为服务LSC，用以维护该UE对应的APG及LSC。这里，当由LSC1作为服务LSC时，LSC2要协同管理AP1向用户UE提供服务；当由LSC2作为服务LSC时，LSC1需要向LSC2进行APG信息的同步，且LSC1需要 协同管理原APG的相关AP为用户UE提供服务。
请参考图16所示的在LSC间的APG更新(加入成员AP)：
由于用户移动，或者网络激活等原因，AP1可以感知到UE1，AP1在感知到UE1时，收集UE1的相关信息(S1601)，如网络接入能力、设备标识等(S1601)，如发现AP1自身能够为AP1服务，则向其归属的LSC2报告新发现的UE1的相关信息(S1602)。
然后，LSC2根据AP1发来的信息，在确定LSC2本地没有该UE1的服务LSC信息时，将向NSC查询UE的服务LSC的信息(S1603)。NSC查询到UE的服务LSC(这里假设为LSC1)的信息，向LSC2发送通知消息，通知LSC2记录UE1的服务LSC为LSC1(S1604)，并且，NSC还向LSC1发送携带有UE1、AP1以及LSC2信息的请求消息(S1605)。
接下来，LSC1收到NSC发送的上述消息后，更新UE1对应的APG，在其中加入AP1(S1606)，并将向更新后的APG列表中的各个成员AP发送APG更新消息，用以进行成员AP的更新配置(S1607)。其中，对于归属于该LSC1的成员AP，LSC1可以直接向该成员AP发送APG更新消息。而对于归属于其他LSC1的成员AP，LSC1可以将通过该成员AP归属的LSC向该成员AP发送APG更新消息，即将APG更新消息发送给该成员AP归属的LSC，然后由该成员AP归属的LSC将该APG更新消息发送给该成员AP。
然后，更新后的APG中的成员AP可以基于多点协作技术，为UE1提供数据服务(S1608)。
请参考图17所示的在LSC间的APG更新(删除成员AP)：
当用户移动导致AP1无法感知到用户，或者AP1要进行休眠而无法再为UE1服务，此时AP1向其归属的LSC2发送用于请求将AP1从UE1对应的APG中删除的请求消息(S1701)。
LSC2收到上述请求消息后，根据本地记录的UE1的服务LSC信息，确定UE1的服务LSC为LSC1，此时，LSC2向LSC1转发上述请求消息(S1702)。
LSC1收到LSC2发送的上述请求消息后，将AP1从UE1对应的APG中删除(S1703)。这里，在删除AP1之后，LSC1还可以进一步判断APG中是否还存 在归属于LSC2的AP，如果不存在，则将LSC2从UE1对应的LSC中删除。
然后，LSC1向更新后的APG中的成员AP发送APG更新消息，用以删除APG中的AP1(S1704)。其中，对于归属于该LSC1的成员AP，LSC1可以直接向该成员AP发送APG更新消息。而对于归属于其他LSC1的成员AP，LSC1可以将通过该成员AP归属的LSC向该成员AP发送APG更新消息，即将APG更新消息发送给该成员AP归属的LSC，然后由该成员AP归属的LSC将该APG更新消息发送给该成员AP。
然后，更新后的APG中的成员AP可以基于多点协作技术，为UE1提供数据服务(S1705)。
作为另外一种实现方式，LSC2在收到上述请求消息后，确定自身不是UE1的服务LSC时，还可以将该请求消息发送给NSC，再通过NSC转发给服务LSC(LSC1)，而不是直接发送给服务LSC(LSC1)
场景3：NSC间的AGP切换(APG Handover)或APG与传统蜂窝网络之间的切换(APG撤销)
当UE从一个NSC的管理范围运动到另一个NSC的管理范围时，要进行NSC间的切换处理，即APG的切换。当UE从超密集网络运动到蜂窝网络(如宏蜂窝或微蜂窝等网络)时，也需要进行切换。原超密集网络在APG中的数量变为0时，需要对APG进行撤销，包括：NSC回收为该UE分配的APG，以及该UE对应的各个LSC删除其记录的UE的服务LSC信息，服务LSC还需要删除UE对应的APG以及LSC。上述两种情况系的切换，有硬切换与软切换两种切换方式。
1)硬切换：当APG内AP数减小为0时，由用户终端感知新的网络。当用户终端由一个超密集网络进入另一个超密集网络时，进行APG的初始化。当用户终端由一个超密集网络进入宏蜂窝或其他网络时，则建立与传统网络的连接并进行数据传输。在切换到新的网络之前，通信有可能中断。
2)软切换：当APG内唯一AP不能满足为用户提供服务时，在断开该唯一AP与UE的连接前，等待UE与新进入的网络(如新UDN网络或蜂窝网络)建立连接后，再在原超密集网络进行APG的撤销。这种切换方式能够在切换到新 的网络过程中尽量避免通信中断。
最后，通过一个具体示例，说明应用本公开实施例所述方法后的网络接入流程。请参考图18，图18给出了超密集网络的部分结构示意图，其中，NSC管理范围内有LSC1和LSC2，其中，AP1～AP3归属于LSC1，AP4～AP7归属于LSC2。假设上述AP均具备为UE的服务能力。UE在移动过程中，先后经过位置1、位置2、位置3和位置4。
当UE到达位置1时，AP1或AP2能够发现UE1，通过APG初始化过程，UE1将获得NSC分配的APG，UE1的服务LSC为LSC1。此时，通过成员AP的添加，最终该APG将包括有AP1和AP2，由AP1和AP2通过多点协作方式为UE1提供数据服务。
当UE到达位置2时，AP3能够发现UE1。此时，通过成员AP的添加，最终该APG将包括有AP1、AP2和AP3，由AP1～AP3通过多点协作方式为UE1提供数据服务。
当UE到达位置3时，AP4能够发现UE1，而AP1将发现UE1离开了其覆盖范围。此时，通过成员AP的添加和删除，最终该APG将包括有AP2、AP3和AP4，由AP2～AP4通过多点协作方式为UE1提供数据服务。
当UE到达位置4时，AP5和AP6将能够发现UE1，而AP2和AP3都将发现UE1离开了其覆盖范围。此时，通过成员AP的添加和删除，最终该APG将包括有AP4、AP5和AP6，由AP2～AP4通过多点协作方式为UE1提供数据服务。在此过程中，由于APG中归属于LSC1的成员AP数量变为0，因此将触发服务LSC的更换，将UE1的服务LSC更换为LSC2。
以上实施例中，一个APG中可以包括归属于多个不同LSC的AP。为简化处理，本公开实施例中也可以在一个APG中仅包括归属于一个LSC的AP，下面将结合附图对该实现方式作进一步的描述。
请参照图19，本公开实施例提供的网络接入点动态组网方法，应用于一超密集网络中中的LSC，该方法包括以下步骤：
步骤191，接入网侧的LSC，接收第一AP在发现第一AP能够服务的第一 UE后发送的第一通知消息，该第一AP是归属于所述LSC的一个AP。
这里，第一AP在其覆盖范围内发现第一UE后，根据自身的服务能力(如网络接入能力、自身负载状态等)以及UE的设备能力(如UE的网络接入能力等)，判断出第一AP可以为第一UE提供服务时，向第一AP归属的第一LSC发送上述第一通知消息。该第一通知消息可以携带有第一AP、第一UE的信息，如设备的标识等信息。
步骤192，所述LSC判断本地是否维护有该第一UE对应的第一APG的信息，其中，所述第一APG中包括有归属于所述LSC、且当前能够服务该第一UE的成员AP。
这里，APG是由所述LSC归属的NSC所分配的，且与UE唯一对应的。本实施例中一个APG中仅包括归属于同一LSC的AP，且在NSC为某个UE分配APG后，由对应的LSC在本地维护该UE的APG的信息。因此，步骤192中，如果所述LSC本地存在所述第一APG的信息，则说明NSC已经为第一UE分配过了APG；如果不存在，则说明NSC尚未为第一UE分配APG。
步骤193，所述LSC在判断出本地维护有所述第一APG的信息时，根据所述第一AP，将第一AP加入到所述第一APG中，并向第一APG中的各个成员AP发送第一APG的更新消息，该更新消息携带有第一APG的成员AP的信息。
这里，由于所述LSC本地维护有所述第一APG的信息，则说明NSC已经为第一UE分配过了APG，此时需要将新发现第一UE的第一AP，加入到第一UE对应的第一APG中，以更新第一APG中的成员AP，并向该第一APG中的各个成员AP发送更新消息，以使各个成员AP更新第一APG中的成员AP的信息。这样，更新后的APG中的成员AP，可以通过多点传输传输方式，由一个AP或多个AP为UE提供数据传输服务。基于以上步骤，本公开实施例实现了以用户为中心，动态更新为用户服务的接入点组合，可以减少用户对网络环境的频繁感知，降低核心网的信令负载。
本公开实施例的上述方法，如果在步骤192中，所述LSC判断出本地未维护所述第一APG信息，则还可以包括以下步骤：
步骤194，所述LSC向核心网侧的网络服务中心设备NSC发送用于请求为 第一UE分配APG的第一请求消息，接收所述NSC针对所述第一请求消息返回的第一配置消息，该第一配置消息携带有NSC新分配的唯一对应于第一UE的第一APG。
这里，在所述LSC本地没有有所述第一APG的信息时，则说明NSC尚未为第一UE分配APG，此时LSC将向NSC请求为第一UE分配APG。NSC可以通过APG ID来唯一标识每个APG。第一配置消息中可以携带第一APG的APG ID等信息。
步骤195，根据该第一配置消息，在本地记录并维护所述第一APG的信息，并向第一APG中的各个成员AP发送第一APG的更新消息，其中，所述第一APG包括有第一AP。
这里，在接收到NSC为第一UE分配的第一APG的信息之后，LSC在本地记录并维护该信息，同时维护第一APG的成员AP。在第一APG初始化时，第一APG中将包括第一AP。然后，LSC将向第一APG中的成员AP(初始时仅包括第一AP)发送第一APG的更新消息，该更新消息中携带有第一UE对应的第一APG中的成员AP的信息，以使各个成员AP更新第一APG中的成员AP。
本公开实施例中，LSC在发现第一APG中的某个AP，如第一AP，不能为第一UE服务时，需要将该AP从第一APG中删除，并通知第一APG中的成员AP更新第一APG的成员信息，此时上述方法还包括以下步骤：
步骤196，所述LSC将第一AP从第一APG中删除，并向第一APG中的各个成员AP发送第一APG的更新消息。
这里，LSC可以通过多种方式，确定第一AP是否能够为第一UE服务。例如，当第一AP因为其自身负荷过大，或者因为需要进入休眠状态灯原因，将不能够再为第一UE服务时，第一AP可以向LSC发送用于请求将第一AP从第一APG中删除的第二请求消息，这样，LSC在接收到该消息后，可以确定第一AP将不能为第一UE服务。再例如，LSC可以周期性检测第一AP的在线状态，比如通过心跳报文等方式，如果发现第一AP故障(如无法接收到第一AP的心跳报文)，则可以确定第一AP将不能为第一UE服务。
本公开实施例中，所述LSC在将第一AP从第一APG中删除后，还需要判 断第一APG中的成员AP是否为0，若是，则删除，删除本地维护的所述第一APG的信息，并向NSC发送用于撤销第一APG的撤销消息，以通知NSC撤销为第一UE分配的APG，回收APG ID等资源。
以上从LSC侧说明了本公开实施例的AP动态组网方法。下面进一步结合图20，说明本公开实施例在NSC侧的实现流程，具体包括以下步骤：
步骤201，核心网侧的NSC，接收接入网侧的本地服务中心设备LSC发送的用于请求为第一UE分配APG的第一请求消息，所述第一请求消息是所述LSC在接收第一AP在发现第一AP能够服务的第一UE后发送的第一通知消息，且判断出所述LSC本地未维护该第一UE对应的第一APG的信息时发送的。
这里，第一AP在发现其所能够服务的第一UE后，向其所归属的LSC发送所述第一通知消息；所述LSC接收到所述第一通知消息后，如果判断出本地未维护有第一UE对应的第一APG的信息，则说明NSC尚未为第一UE分配APG，此时该LSC将向其所归属的NSC发送上述第一请求消息，以请求NSC为第一UE分配对应的APG。
步骤202，NSC根据所述第一请求消息，为第一UE分配一与该第一UE对应的第一接入点组合APG，记录第一UE、第一APG以及所述LSC之间的对应关系，并向所述LSC发送携带有第一APG的信息的第一配置消息。
这里，NSC根据第一请求消息，为第一UE分配一个唯一对应的第一APG，不同的APG可以使用APG ID来唯一标识。NSC还可以在本地记录第一UE、第一APG以及所述LSC之间的对应关系。NSC在分配第一APG之后，将向LSC发送第一配置消息，使得LSC据此配置并维护第一UE对应的第一APG的相关信息。
本公开实施例中，在第一APG中的成员AP都被删除后，NSC还可以接收LSC在第一APG中的成员AP数量为0时发送的用于撤销第一APG的撤销消息，此时，所述NSC根据所述撤销消息，撤销为所述第一UE分配的第一APG，并删除本地记录的第一UE、第一APG以及所述LSC之间的对应关系。
本公开实施例的接入网动态组网方法，在应用于超密集网络中的AP时，其处理流程如图21所示，包括：
步骤211，第一AP在发现自身能够服务的第一UE后，向第一AP归属的第一LSC发送一用于通知发现第一UE的第一通知消息。
步骤212，第一AP接收第一LSC发送的第一APG的第一更新消息，该第一更新消息携带有第一UE对应的第一APG的成员AP的信息，第一APG中包括有当前能够服务该第一UE的成员AP。
步骤213，第一AP根据第一更新消息，在本地维护第一UE对应的第一APG，并与第一APG中的成员AP通过多点协调传输方式为第一UE提供数据传输服务。
在上述步骤213之后，第一AP还可以动态更新接入点组合，此时上述方法还包括：第一AP接收第一LSC发送的第一APG的第二更新消息，所述第二更新消息携带有更新后的第一APG；第一AP根据所述第二更新消息，更新本地维护的第一APG。
第一AP可能由于自身原因(如工作负荷高、休眠周期到达等)或第一UE的原因(如第一UE离开第一AP的覆盖范围内、第一AP与第一UE之间距离过大导致信号质量不满足预定指标等)，将不能再继续为第一UE服务后，此时上述方法还包括：第一AP向第一LSC发送用于请求将第一AP从第一APG中删除的请求消息，并删除本地维护的第一APG。通过该请求消息，将触发第一UE的服务LSC删除第一APG中的第一AP，以更新第一APG。
通过上述步骤，第一AP在本地维护了第一APG的成员AP的信息，实现了以用户为中心的接入点组网方案，能够动态更新为用户服务的接入点组合，可以减少用户对网络环境的频繁感知，降低核心网的信令负载。
上文中分别从LSC、NSC、和AP角度对本公开实施例的接入点动态组网方法进行了说明。下面将进一步介绍实现上述方法LSC、NSC和AP。

以上所述是本公开的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本公开所述原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本公开的保护范围。
