Description

一种网络资源的配置方法、装置、系统及网络通信方法 技术领域
本文涉及移动通信领域，尤其涉及一种网络资源的配置方法、装置、系统及网络通信方法。
背景技术
随着移动通信的普及，在未来10年内，无线移动业务量预计出现上千倍的增长，而当前基于宏小区的蜂窝无线接入网络显然无法提供足够大的容量以满足如此巨大的移动业务需求。目前，超密集网络(Ultra Dense Network，UDN)被业界认为是满足如此巨大的业务需求的主要驱动。
UDN通过增加网络节点的部署密度实现网络容量的增长，即通过增加无线接入网节点(radio access network node，RAN-node)的部署密度实现网络容量的增长，而无线接入网节点的密集部署又拉近了用户和无线接入网节点之间的距离，这种近距离的无线通信一方面可以确保通信链路的高可靠性，另一方面还可以提高区域内频谱的复用效率，从而可以进一步提高网络容量。与此同时，用户和无线接入网节点之间的近距离通信，使得毫米波可以在超密集网络中使用，毫米波丰富的频率资源为超密集网络提供了更大的带宽，从而又进一步提高了网络容量。无线接入网节点是用户设备可以通过无线通信链路接入网络的接入网设备，比如基站(NodeB，eNB)，低功率节点(Low Power Node，LPN)或接入点(Access Point，AP)等都是无线接入网节点。
UDN可以提高网络容量，在提高网络容量的同时，未来的网络也不希望增加网络的资本支出(Capital Expenditure，CAPEX)和运营支出(Operating Expense，OPEX)，这就意味着超密集网络的部署需要减少人为的计划、优化和管理，可以根据网络拓扑、网络负荷、业务需求等在室内、室外的热点区域或者大业务量区域完成灵活快速部署，并实现自配置、自优化和自治愈。实现所有这些目标，业界普遍认为超密集网络需要采用无线回程 (wireless backhaul)，而不再像现有网络的无线接入网节点普遍通过有线连接(如光纤或电缆等)接入核心网设备以及实现无线接入网节点之间的连通，而是通过无线连接实现无线接入网节点之间的连通，甚至通过无线连接接入核心网设备。
无线回程链路可以使用与无线接入链路(Access link)，即用户设备通过无线通信链路接入接入网设备的链路，相同或者不同的频率资源，UDN中大量无线回程链路和无线接入链路的同时存在，对每个链路之间如何使用资源，如何解决每个链路之间的干扰提出了挑战。

本发明的较佳实施方式
下面通过具体实施方式结合附图对本发明作进一步详细说明。
满足未来10年上千倍业务量增长的预期，UDN将被广泛部署以承担大量业务流量。UDN可以被部署在室内、室外热点区域或者任何有大业务量需求的区域，比如人口密集的居民区，写字楼，购物中心，体育场，大型露天集会场所，机场，交通枢纽等。
如图1为超密集网络中网络的接入网网络拓扑结构的示意图，120-1～120-7为一定区域内密集部署的无线接入网节点，110-1和110-2为资 源协调中心(Resource Coordination Center，RCC)。为不增加网络中部署的CAPEX和OPEX，实现灵活快捷部署该网络，7个无线接入网节点中，只有120-2和120-5可以分别通过有线接口130-2和130-1接入资源协调中心110-2和110-1，而7个无线接入网节点可以通过无线接口(无线回程链路140-1～140-9)与周围的无线接入网节点之间通信，本申请将可以通过有线接口接入资源协调中心的无线接入网节点称为资源协调中心可接入节点；资源协调中心(110-1和110-2)负责一定区域内无线接入网节点无线资源的管理和协调，包括无线接入链路和无线回程链路的资源管理和协调。资源协调中心(110-1和110-2)是一个逻辑功能实体，具体物理实现时，资源协调中心(110-1和110-2)可以在已有接入网设备(如宏基站)上实现，也可以通过新增独立的物理软硬件设备实现，也可以在特定的接入点上实现。无线接入网节点(120-1～120-7)是一种接入网设备，比如基站(NodeB，eNB)，低功率节点(Low Power Node，LPN)，接入点(Access Point，AP)，无线中继接入设备(Relay)，家庭小基站(Femto)等，无线接入网节点(120-1～120-7)一方面可以通过无线接入链路与用户设备(手机或平板电脑等)通信，另一方面可以通过无线回程链路与周围的无线接入网节点通信。以图中的无线接入网节点120-3为例，无线接入网节点120-3可以通过无线接入链路160-1与用户设备150-1通信，另一方面又可以通过无线回程链路140-6、140-7和140-8分别与无线接入网节点120-2、120-4和120-7通信。要实现无线网络的密集部署，势必要求无线接入网节点的信号覆盖范围较传统蜂窝小区小，因此120-1～120-7的无线接入网节点尤其指发射功率相比于传统蜂窝系统的宏基站小的低功率小基站；有线接口(130-1和130-2)是指采用铜，光纤等有线介质实现无线接入网节点和资源协调中心之间的连接的接口。无线接口(140-1～140-9)是指采用无线空中接口实现无线接入网节点之间通信的无线回程接口；无线接入网节点120-3可以通过无线回程链路140-6、140-7和140-8分别与无线接入网节点120-2、120-4和120-7通信，这些回程链路140-6、140-7、140-8如果共享使用相同的资源，相互之间很可能会相互干扰。此外，以无线接入网节点120-3和无线接入网节点120-4为例，两者部署位置距离较近，两者的无线接入链路覆盖(图中灰色阴影)有重叠区域，当无线接入网节点120-3和无线接入网节点120-4使用相同的资源分别与重叠覆 盖区域内的用户设备通信时，势必造成两者无线接入链路之间的干扰，更为严重的情况，当无线接入网节点120-3和无线接入网节点120-4部署距离足够近，可以相互接收到对方的发射信号的情况下，无论用户设备是否处于无线接入网节点120-3和无线接入网节点120-4的重叠覆盖区域，当无线接入网节点120-3和无线接入网节点120-4使用相同的资源与用户设备通信时，两者的无线接入链路之间必然干扰。除了无线回程链路之间的相互干扰，无线接入链路之间的相互干扰之外，由于这些无线接入网节点一方面具备无线接入模块可以与用户设备通信，另一方面具备无线回程模块可以与其他无线接入网节点通信，密集部署再加上无线接入网节点同时具备无线接入和无线回程两个链路，如果无线回程链路和无线接入链路共享相同的资源，那么势必造成同一个无线接入网节点的无线回程链路和无线接入链路之间的相互干扰。
网络中大量无线回程链路和无线接入链路的同时存在，对每个链路之间如何使用资源，如何解决无线回程链路之间，无线接入链路之间以及无线回程和无线接入链路之间的干扰提出了挑战。
如图2所示为本发明实施例提供的网络资源的配置方法的流程图，请参见图2，该方法开始后，包括：
S201：无线接入网节点获取网络中其相邻无线接入网节点的资源信息，所述资源信息包括：网络资源集和所述相邻无线接入网节点已使用的网络资源。所述网络资源集是提供给该网络中每个无线接入网节点之间的无线回程链路和/或无线接入链路使用的网络资源的集合。所述网络资源集由资源协调中心根据预定区域内(即该网络中)可能开启的无线接入网节点的数量，当前的系统带宽，预定区域内可能接入的用户设备的数量，资源使用情况等确定。可选地，所述网络资源集包括：提供给预定区域内的每个无线接入网节点之间的无线回程链路使用的网络资源的集合；或者是提供给预定区域内的每个无线接入网节点的无线接入链路使用的网络资源的集合；或者是提供给预定区域内的每个无线接入网节点的无线回程链路和无线接入链路使用的网络资源的集合。所述预定区域内可以是指网络所涵盖的区域，由部署所述网络的所有者确定，也可以由资源协调中心根据相关布网经验值，比如资源协调中心可接入节点的容量，资源协调中心可接入节点与资源协调中心之间的 有线接口的容量，资源协调中心的负载等确定。所述网络资源集中的每个网络资源，可以是频率域上分配整个系统频带而时间域上周期性非连续分配的资源，也可以是时间域上连续分配而频率域上只分配部分频带的资源，还可以是时间域上非连续分配，每个非连续分配的时间段上只分配部分频带的资源等。

在本步骤中，以无线接入网节点X获取其预定范围内相邻的一个无线接入网节点Y广播的资源信息为例，即以无线接入网节点X获取预定范围内其中任意一个相邻无线接入网节点Y广播的资源信息为例，资源信息可以是：资源信息1：包括网络资源集及无线接入网节点Y已使用的网络资源；或者，资源信息2：包括网络资源集、无线接入网节点Y已使用的网络资源、无线接入网节点Y的第一相邻无线接入网节点列表及无线接入网节点Y的第二相邻无线接入网节点列表。
资源协调中心在分配所述网络资源集后，资源协调中心可接入节点通过与所述资源协调中心之间的有线接口获取所述分配的网络资源集；资源协调中心可接入节点为其他可搜索到该资源协调中心可接入节点的无线接入网节点的第一相邻无线接入网节点。其他无线接入网节点可搜索到资源协调中心可接入节点，是指所述其他无线接入网节点的射频装置可以接收到资源协调中心可接入节点，或者所述其他无线接入网节点的射频装置可以接收到资源协调中心可接入节点且资源协调中心可接入节点的信号强度或信号质量好于预定门限。步骤201中，无线接入网节点获取其相邻无线接入网节点的资源信息，若所述无线接入网节点为资源协调中心可接入节点，则特别的，所述无线接入网节点通过与资源协调中心之间的有线接口获取所述资源信息，且所述资源信息为网络资源集。步骤201中，无线接入网节点获取其相邻无线接入网节点的资源信息，若所述无线接入网节点的相邻无线接入网节点为资源协调中心可接入节点，则所述无线接入网节点从该所述相邻无线接入网节点(即资源协调中心可接入节点)获取的资源信息为资源信息1时，所述资源信息1为网络资源集；所述获取的资源信息为资源信息2时，所述资源信息2包括网络资源集和所述该相邻无线接入网节点(即资源协调中心可接入节点)的第二相邻无线接入网节点的信息。以无线接入网节点X获取其相邻无线接入网节点Y广播的资源信息为例，若所述相邻无线接入网节点Y为资源协调中心可接入节点，则所述相邻无线接入网节点Y从资源协调中心获取的资源信息为网络资源集，那么所述无线接入网节点X从所述相邻无线接入网节点Y接收到的资源信息1仅为网络资源集；所述无线接入网节点X从所述相邻无线接入网节点Y接收到的资源信息2包括网络资源集和无线接入网节点Y的第二相邻无线接入网节点列表。
S202：无线接入网节点根据所获取的资源信息，从网络资源集中选择对已被网络中的其他无线接入网节点使用的网络资源不产生干扰的待使用的网络资源。
可选的，若所述无线接入网节点获取的所述相邻无线接入网节点的资源信息是资源信息1：网络资源集和所述相邻无线接入网节点已使用的网络资源，则所述无线接入网节点从所述网络资源集中选择对已被网络中的其他无线接入网节点使用的网络资源不产生干扰的待使用的网络资源为：所述无线接入网节点根据所述接收到的其每个相邻无线接入网节点广播的资源信息1，从所述资源信息1中所包含的网络资源集中选择未被所述无线接入网节点的每个相邻无线接入网节点所使用的网络资源作为待使用的网络资源；或者从所述资源信息1中所包含的网络资源集中选择被所述无线接入网节点的一个或者多个相邻无线接入网节点使用的但允许多个无线接入网节点共享使用的网络资源作为待使用的网络资源。其中所述每个相邻无线接入网节点所使用的网络资源为所述每个相邻无线接入网节点所广播的资源信息1中包含的所述每个相邻无线接入网节点所使用的网络资源。
可选的，若所述无线接入网节点获取的所述相邻无线接入网节点的资源信息为资源信息2，包括：网络资源集、所述相邻无线接入网节点已使用的网络资源、所述相邻无线接入网节点的第一相邻无线接入网节点信息和所述相邻无线接入网节点的第二相邻无线接入网节点信息，则所述无线接入网节点从所述网络资源集中选择对已被网络中的其他无线接入网节点使用的网络资源不产生干扰的待使用的网络资源的方法包括：无线接入网节点遍历其第一相邻无线接入网节点信息中每个第一相邻无线接入网节点的第二相邻无线接入网节点信息，找出其中已经完成了网络资源配置且非所述无线接入网节点的相邻无线接入网节点的隐藏节点，其中所述无线接入网的第一相邻无线接入网节点信息中每个第一相邻无线接入网节点的第二相邻无线接入网节点信息，包含在所述该无线接入网节点从所述的第一相邻无线接入网节点信息中每个第一相邻无线接入网节点处获取到的资源信息2中；所述无线接入网节点从网络资源集中选择未被其第一相邻无线接入网节点信息中的第一相邻无线接入网节点使用的，也未被所述隐藏节点使用的网络资源作为待时用的 网络资源；或者，选择被其第一相邻无线接入网节点信息中的第一相邻无线接入网节点使用或被所述隐藏节点使用，但允许多个无线接入网节点共享使用的网络资源作为待使用的网络资源，其中，所述无线接入网的第一相邻无线接入网节点信息中每个第一相邻无线接入网节点使用的网络资源，包含在所述该无线接入网节点从所述的第一相邻无线接入网节点信息中每个第一相邻无线接入网节点处获取到的资源信息2中，所述隐藏节点使用的网络资源，包含在所述该无线接入网节点从其相邻无线接入网节点处获取到的资源信息2中。在本实施例中，由于当所述隐藏节点的回程链路和所述无线接入网节点的回程链路使用相同的网络资源时，所述隐藏节点的回程链路和所述无线接入网节点的回程链路之间会产生干扰，因此，所述无线接入网节点需要先找出所述隐藏节点已使用的网络资源后，再进行网络资源的选择，这样，确保了所述无线接入网节点使用所述选择的网络资源在进行通信时不会与所述隐藏节点的通信产生干扰。
若所述网络资源集为回程链路使用的网络资源的集合，则上述选择的待使用的网络资源为回程链路使用的网络资源；若所述网络资源集为无线接入链路使用的网络资源的集合，则上述选择的待使用的网络资源为无线接入链路使用的网络资源；若所述网络资源集为回程链路的网络资源集和无线接入链路的网络资源集，则上述选择的待使用的网络资源包括：回程链路的网络资源和无线接入链路的网络资源。可选地，所述回程链路的网络资源与所述无线接入链路的网络资源不同。
S203：无线接入网节点根据所选择的待使用的网络资源，将其资源信息在网络中进行通知。可选地，无线接入网节点将其资源信息在网络中以广播的方式进行通知。对应于上述步骤S201中无线接入网节点获取到的相邻无线接入网节点的资源信息为资源信息1时，则所述无线接入网节点广播的资源信息包括：网络资源集和所述无线接入网节点选择的待使用的网络资源(即所述该无线接入网节点所使用的网络资源)；或者，对于上述步骤S201中无线接入网节点获取到的相邻无线接入网节点的资源信息为资源信息2时，则所述无线接入网节点广播的资源信息包括：网络资源集、所述无线接入网节点选择的待使用的网络资源(即所述该无线接入网节点所使用的网络 资源)、所述该无线接入网节点的第一相邻无线接入网节点信息，和所述该无线接入网节点的第二相邻无线接入网节点信息。
本实施例中，以无线接入网节点X获取其相邻的一个无线接入网节点Y广播的资源信息2为例，即以无线接入网节点X获取它的每个相邻无线接入网节点中的任意一个相邻无线接入网节点Y广播的资源信息2为例，若在无线接入网节点X接收无线接入网节点Y广播的资源信息2前，无线接入网节点Y的第二相邻无线接入网节点列表中的节点Z根据以上步骤S201～S203选择并广播了节点Z的资源信息之后，无线接入网节点Y接收无线接入网节点Z广播的资源信息后，更新其广播的资源信息，在此前无线接入网节点Y广播的资源信息上增加其第二相邻无线接入网节点Z选择的网络资源，则无线接入网节点X接收到的无线接入网节点Y广播的资源信息2包括：网络资源集、无线接入网节点Y已使用的网络资源、无线接入网节点Y的第一相邻无线接入网节点列表和无线接入网节点Y的第二相邻无线接入网节点列表，还可以包括无线接入网节点Y的第二相邻无线接入网节点列表中已经完成网络资源配置的相邻无线接入网节点Z所使用的网络资源。
本实施例主要是对网络中的每个无线接入网节点所使用的网络资源进行的合理配置，使得在该网络中的通信能够实现干扰不强，甚至是互不干扰的效果。
本发明实施例还提供了一种网络通信方法，包括：网络中每个无线接入网节点根据如上述步骤S201～S203所述的网络资源的配置方法配置所使用的网络资源；所述无线接入网节点以时分复用的方式使用所述配置的网络资源与至少两个或两个以上的相邻无线接入网节点进行通信。这样，仍然能使得在同一时间内整个网络中的每个无线接入网节点通信的回程链路之间不会因使用同一网络资源而产生干扰，影响其通信效果，增加了用户的体验。
如图3所示，为本发明实施例提供的网络资源的配置装置的结构图，设置于无线接入网节点中，请参见图3，所述网络资源的配置装置30包括：网络资源获取模块301、网络资源选择模块302及通知模块303，所述网络资源 获取模块301设置为所述无线接入网节点获取其相邻无线接入网节点的资源信息，所述资源信息至少包括：网络资源集和所述相邻无线接入网节点已使用的网络资源；所述网络资源选择模块302设置为所述无线接入网节点根据所述网络资源获取模块301获取的资源信息，从网络资源集中选择对已被网络中的其他无线接入网节点使用的网络资源不产生干扰的待使用的网络资源；所述通知模块303设置为所述无线接入网节点根据所述网络资源选择模块302选择的待使用的网络资源，将其资源信息在网络中进行通知。可选地，所述网络资源获取模块301是设置为所述无线接入网节点通过接收其每个相邻无线接入网节点的广播获取其所述每个相邻无线接入网节点的资源信息；可选地，所述通知模块303是设置为通过广播的方式将其资源信息在网络中进行通知。本发明实施例里所提出的上述网络资源的配置装置的每个功能模块，具体实现时可以是包括处理器、存储器以及运行在处理器上的程序等硬件和软件的结合。

在另一实施例中，所述通知模块303是设置为：若所述网络资源获取模块301获取的资源信息为资源信息1；则所述无线接入网节点在网络中通知的信息包括：网络资源集和其选择的待使用的网络资源；或者，若所述网络资源获取模块301获取的资源信息为资源信息2，则所述无线接入网节点的在网络中通知的信息包括：网络资源集、其选择的待使用的网络资源(即所述该无线接入网节点所使用的网络资源)、所述该无线接入网节点的第一相邻无线接入网节点信息和所述该无线接入网节点的第二相邻无线接入网节点信息。可选地，同样以无线接入网节点X为例，对于网络资源获取模块301获取到的相邻无线接入网节点广播的资源信息为资源信息1的情况，通知模块303广播的资源信息为：网络资源选择模块302选择的待使用的网络资源和网络资源集；对于网络资源获取模块301获取到的相邻无线接入网节点广播的资源信息为资源信息2的情况，所述通知模块303广播的资源信息为网络资源集、网络资源选择模块302选择的待使用的网络资源、无线接入网节点X的第一相邻无线接入网节点列表以及无线接入网节点X的第二相邻无线接入网节点列表。
在另一实施例中，所述资源选择模块302是设置为：对于网络资源获取模块301获取到的相邻无线接入网节点广播的资源信息为资源信息1，包括网络资源集和所述相邻无线接入网节点已使用的网络资源的情况，则资源选择模块302从所述网络资源集中选择一个未被无线接入网节点的所述每个相邻无线接入网节点使用的，或者选择被无线接入网节点的一个或者多个相邻无线接入网节点使用但允许多个无线接入网节点共享使用的网络资源；对于网络资源获取模块301获取到的其相邻无线接入网节点广播的资源信息为资源信息2，包括网络资源集、所述相邻无线接入网节点已使用的网络资源、所述相邻无线接入网节点的第一相邻无线接入网节点信息和所述相邻无线接入网节点的第二相邻无线接入网节点信息的情况，则资源选择模块302包括：隐藏节点确定子模块，设置为无线接入网节点遍历其第一相邻无线接入网节点信息中每个第一相邻无线接入网节点的第二相邻无线接入网节点信息，找出其中完成了网络资源的配置且非所述无线接入网节点的相邻无线接入网节点的隐藏节点；网络资源选择子模块，设置为所述无线接入网节点从网络资源集中选择未被其第一相邻无线接入网节点信息中的第一相邻无线接入网节点使用的，也未被所述隐藏节点查找子模块查找到的隐藏节点使用的网络资源作为待使用的网络资源；或者，设置为所述无线接入网节点选择被其第一相邻无线接入网节点信息中的第一相邻无线接入网节点使用或被所述隐藏节点使用，但允许多个无线接入网节点共享使用的网络资源作为待使用的网络资源。
本实施例提供的网络资源的配置装置，能够所获取到的网络资源集中的每个网络资源合理的分配给网络中的每个无线接入网节点使用，使得该网络中的通信实现干扰不强甚至是互不干扰的效果，提高了网络的资源使用效率，提升了超密集网络的容量。
本发明实施例还提供了一种网络资源的配置系统，所述系统包括：资源协调中心及若干个无线接入网节点；所述资源协调中心与其中至少一个无线接入网节点之间有有线连接；在所述这些无线接入网节点上设置如上述任一实施例所述的网络资源的配置装置。在本网络资源的配置系统中，通过所述 网络资源的配置装置对其中每个无线接入网节点使用的网络资源进行合理的配置，使得所述网络中的通信能够减少干扰，甚至没有干扰，对于该网络中的资源使用效率有了大大地提高。
为更清楚的解释上述网络资源的配置方法及装置，下面将以超密集网络的网络资源的配置方法为例，详细说明本发明实施例方案。其中图4为本发明实施例的超密集网络接入网网络拓扑的示意图，如图4所示，区域内部署有7个无线接入网节点(410AP1，420AP1，……470AP7)。其中410AP1为资源协调中心可接入节点，与资源协调中心480之间通过有线接口401连接，可通过该有线接口401从480处获取存储在480上的信息。其他6个无线接入网节点与480没有有线接口连接，都至少具备一个无线回程模块，可以检测监听周围的无线接入网节点并与周围的无线接入网节点通信，以无线接入网节点420AP2为例，无线接入网节点AP2可以监听检测到无线接入网节点AP1、AP3及AP5，无线接入网节点AP2可以通过无线回程链路400-1、400-2和400-6分别与无线接入网节点AP1、AP3及AP5通信。表格1给出了图4的接入网网络拓扑结构中，每个无线接入网节点可以检测监听到的相邻无线接入网节点的情况。

表格1
图4中的每个AP除了至少具备一个无线回程模块外，还具备无线接入 模块，可以实现无线覆盖(图中未示出)，通过无线接入链路与用户设备通信。本发明实施例中以图4所示的无线回程链路为例说明本发明实施例提出的超密集网络的资源配置方法，需要说明的是，以下所有实施例的实施方法，同样适用于图4中未示出的每个无线接入网节点的无线接入链路，并且，每个无线接入网节点的无线回程链路和无线接入链路，可以在以下每个实施例的一次实施过程中完成资源的选择。
实施例一：
图5以图4的超密集网络接入网网络拓扑示意图为例，给出了本发明实施例一提供的超密集网络的网络资源的配置方法的实施流程图，包括：
S501：资源协调中心可接入节点AP1从资源协调中心480处获得网络资源集，并广播所述网络资源集。
AP1通过图4所示的有线接口401从资源协调中心480处获得所述网络资源集。网络资源集是由资源协调中心480分配的，用于提供给图4中每个无线接入网节点之间的无线回程链路的网络资源的集合。即网络资源集是提供给预定区域内的每个无线接入网节点之间的无线回程链路使用的网络资源的集合，由资源协调中心根据预定区域内可能开启的无线接入网节点的数量，当前的系统带宽，预定区域内可能接入的用户设备的数量，资源使用情况等确定。这里的预定区域，可以是指图4所示的UDN接入网网络所涵盖的区域，由部署所述网络的所有者确定，也可以由无线协调中心根据相关布网经验值，比如资源协调中心可接入节点的容量，资源协调中心可接入点与资源协调中心之间的有线接口的容量，资源协调中心的负载等确定。
可选的，网络资源集中的每个网络资源，可以是频率域上分配整个系统频带而时间域上周期性非连续分配的资源，也可以是时间域上连续分配而频率域上只分配部分频带的资源，还可以是时间域上非连续分配，每个非连续分配的时间段上只分配部分频带的资源，图6为本实施例提供的三种网络资源在时间域与频率域的示意图，请参见图6所示：
图6-1示例了一种频率域上分配整个系统频带而时间域上周期性非连续分配的网络资源，以周期T分配，包括在周期T内，t0～t1的整个系统频带6-1-10，以及t2～t3的整个系统频带6-1-30；
图6-2示例了一种时间域上连续分配而频率域上只分配部分频带的网络资源，包括如图所示时间内连续分配的频率域上的两部分频带资源6-2-10和6-2-30；
图6-3示例了一种时间域上非连续分配，每个非连续分配的时间段上只分配部分频带的网络资源，以周期T分配，包括在周期T内，t0～t1时间内的部分频带6-3-10和t2～t3时间内的部分频带6-3-20。
本实施例以无线回程链路的资源配置为例，当然，本实施例也同样适合无线接入链路的资源配置，当本实施例应用于无线接入链路时，网络资源集是提供给预定区域内的每个无线接入网节点的无线接入链路使用的网络资源的集合，也由资源协调中心根据上文提到因素确定，且资源协调中心可接入节点AP1从资源协调中心480处获得所述网络资源集后，AP1选择一个网络资源用于AP1的无线接入链路，然后AP1广播所述网络资源集以及所述选择的用于AP1的无线接入链路的网络资源。可选的，当需要通过本实施例的一次实施过程完成无线回程链路和无线资源链路的资源选择的时候，资源协调中心广播的所述网络资源集中，可以包含提供给预定区域内的每个无线接入网节点使用的用于无线接入网节点间的无线回程链路和用于无线接入网节点的无线接入链路的网络资源的集合。
本实施例假设资源协调中心可接入节点AP1从资源协调中心480处获得的网络资源集包括5个网络资源，分别为{网络资源X1，网络资源X2，……网络资源X5}。
S502：其他无线接入网节点接收预定范围内每个相邻无线接入网节点的广播(资源信息1：网络资源集和选择的网络资源)；选择所要使用的网络资源；并广播网络资源集和所述选择的网络资源。可选地，包括3个子步骤，分别为：
子步骤1：其他无线接入网节点接收预定区域内每个相邻无线接入网节点的广播(资源信息1：网络资源集和选择的网络资源)；
子步骤2：其他无线接入网节点选择所要使用的网络资源；
子步骤3：其他无线接入网节点广播所述网络资源集和所述选择的网络 资源。
在本实施例中，以图4的超密集网络接入网网络拓扑示意图为例，假设该UDN网络中，每个无线接入网节点AP开启后即发送各自的小区发现信号，因此每个无线接入网节点AP开启后均能相互检测到相邻的无线接入网节点AP。然而每个无线接入网节点AP需要等待资源协调中心可接入节点AP1从资源协调中心480处获取到网络资源集合后，才能开始网络资源的选择过程，这里假设图中每个无线接入网节点AP实际选择网络资源的顺序为AP2-AP3-AP4-AP5-AP6-AP7，则每个无线接入网节点AP监听预定范围内每个相邻无线接入网节点的广播，选择自身AP所要使用的网络资源并广播网络资源集和所述选择的网络资源的过程为：
无线接入网节点AP2搜索预定范围内的相邻无线接入网节点，接收所能搜索到的每个相邻无线接入网节点广播的资源信息1；这里，预定范围是指能被AP2的射频接收装置接收到的范围，或者指能被AP2的射频接收装置接收到且信号强度或信号质量好于预定门限的范围，或者指能被AP2的射频接收装置接收到的且信号强度或信号质量按照从好到差排列的前N个无线接入网节点的范围，或者以其他方式确定的范围。其中无线接入网节点AP2搜索预定范围内的相邻无线接入网节点的行为，也可以在AP2开启之后到本步骤之前的任何时间点完成。根据表格1可知，无线接入网节点AP2预定范围内有3个相邻无线接入网节点，包括AP1、AP3及AP5，无线接入网节点AP2接收AP1、AP3及AP5广播的资源信息1，可选的，接收的资源信息1是指AP1、AP3及AP5广播的网络资源集，以及如果AP1、AP3及AP5广播的话，接收AP1、AP3及AP5广播的三者各自选择的网络资源。由于AP1为资源协调中心可接入节点，可以通过有线接口401接入资源协调中心，也可以通过有线接口接入网络，比如接入网络中的服务网关、数据网关等(图4中未示出)，因此资源协调中心可接入节点AP1自身无需配置无线回程链路，故AP1只广播从资源协调中心480处获得的网络资源集{网络资源X1，网络资源X2，……网络资源X5}(即步骤501：资源协调中心可接入节点AP1广播的信息)，因此无线接入网节点AP2接收无线接入网节点AP1广播的资源信息1为网络资源集。根据本实施例假设的每个无线接入网节点AP实际选 择网络资源的顺序，无线接入网节点AP3和无线接入网节点AP5在无线接入网节点AP2之后选择网络资源，因此，在无线接入网节点AP2接收预定区域内每个相邻无线接入网节点的广播，选择确定所要使用的网络资源并广播网络资源集和所选择的网络资源之前，无线接入网节点AP3和无线接入网节点AP5尚未广播资源信息1。无线接入网节点AP2选择所要使用的网络资源，是指AP2从所接收到的预定范围内每个相邻无线接入网节点广播的网络资源集中选择一个未被预定范围内每个相邻无线接入网节点使用的，或者虽然被预定范围内某个相邻无线接入网节点使用但允许多个无线接入网节点共享使用的网络资源。这里，无线接入网节点AP2的三个相邻无线接入网节点无线接入网节点AP1、AP3及AP5均未广播选择的网络资源，因此无线接入网节点AP2可以在网络资源集中随意选择一个网络资源；或者无线接入网节点AP2可以根据其业务流量需求和/或容量，若无线接入网节点AP2可以获得图4所示的UDN网络中其他无线接入网节点AP的业务流量需求、容量等信息时，AP2还可以根据所获取的这些信息综合考虑，从网络资源集中选择一个网络资源；此外，若无线接入网节点AP2能获得来自网络或者来自运营者的资源选择的一些指导规则，无线接入网节点AP2在选择网络资源时还需要接受这些指导规则的限定。本实施例假设无线接入网节点AP2选择了网络资源X1，即AP2使用网络资源X1在无线回程链路400-1上与AP1通信。无线接入网节点AP2广播其资源信息包括：网络资源集{网络资源X1，网络资源X2，……网络资源X5}和选择的所述网络资源X1。
无线接入网节点AP3搜索预定范围内的相邻无线接入网节点，接收所能搜索到的每个相邻无线接入网节点广播的资源信息1。根据表格1可知，无线接入网节点AP3预定范围内有6个相邻无线接入网节点AP1、AP2、AP4、AP5、AP6及AP7。同无线接入网节点AP2接收所能搜索到的每个相邻无线接入网节点广播的资源信息1时的描述，AP1广播的资源信息1为网络资源集{网络资源X1，网络资源X2，……网络资源X5}。根据本实施例假设的每个无线接入网节点AP实际选择网络资源的顺序，在无线接入网节点AP3接收预定区域内每个相邻无线接入网节点的广播，选择确定所要使用的网络资源并广播网络资源集和所选择的网络资源之前，无线接入网节点AP4～AP7尚未广播资源信息1。无线接入网节点AP2广播的资源信息1为网络资源集 {网络资源X1，网络资源X2，……网络资源X5}和AP2所选择的网络资源X1。无线接入网节点AP3选择所要使用的网络资源，即无线接入网节点AP3从所接收到的预定范围内每个相邻无线接入网节点广播的网络资源集中选择一个未被预定范围内每个相邻无线接入网节点使用的，或者虽然被预定范围内某个相邻无线接入网节点使用但允许多个无线接入网节点共享使用的网络资源。本实施例中假设网络资源集中所有的网络资源均不允许被多个无线接入网节点共享使用，网络资源X1已经被无线接入网节点AP3的相邻无线接入网节点AP2使用，因此无线接入网节点AP3不能选择网络资源X1，这里假设无线接入网节点AP3选择了网络资源X2，即AP3使用网络资源X2在无线回程链路400-2和无线回程链路400-3上分别与AP2和AP1通信，且AP3采用时分复用方式使用所述网络资源X2在400-2和400-3上分别与AP2和AP1通信。无线接入网节点AP3广播其资源信息，即所述从AP1/AP2获取的网络资源集{网络资源X1，网络资源X2，……网络资源X5}和其选择的所述网络资源X2。
无线接入网节点AP4搜索预定范围内的相邻无线接入网节点，接收所能搜索到的每个相邻无线接入网节点广播的资源信息1。根据表格1可知，无线接入网节点AP4预定范围内有3个相邻无线接入网节点，为：AP1、AP3及AP7。AP4接收AP1、AP3及AP7广播的资源信息1，同理，AP1广播的资源信息1为网络资源集{网络资源X1，网络资源X2，……网络资源X5}。无线接入网节点AP3广播的网络资源信息1为网络资源集和所选择的网络资源X2，无线接入网节点AP7尚未广播资源信息1。无线接入网节点AP4选择所要使用的网络资源，网络资源X2已经被无线接入网节点AP4的相邻无线接入网节点AP3使用，因此无线接入网节点AP4不能选择网络资源X2，这里假设无线接入网节点AP4选择了网络资源X1，即AP4使用网络资源X1在无线回程链路400-4和无线回程链路400-5上分别与AP1和AP3通信，且AP4采用时分复用方式使用所述网络资源X1在400-4和400-5上分别与AP1和AP3通信。无线接入网节点AP4广播其资源信息，即所述从AP1/AP3获取的网络资源集{网络资源X1，网络资源X2，……网络资源X5}和选择的所述网络资源X1。
无线接入网节点AP5搜索预定范围内的相邻无线接入网节点，接收所能搜索到的每个相邻无线接入网节点广播的资源信息1。根据表格1可知，无线接入网节点AP5预定范围内有3个相邻无线接入网节点AP2、AP3即AP6。无线接入网节点AP5接收无线接入网节点AP2、AP3及AP6广播的资源信息1，同理，无线接入网节点AP2广播的资源信息1为网络资源集{网络资源X1，网络资源X2，……网络资源X5}和其所选择的网络资源X1，无线接入网节点AP3广播的资源信息1为网络资源集和其所选择的网络资源X2，无线接入网节点AP6尚未广播资源信息1。无线接入网节点AP5选择所要使用的网络资源，网络资源X1和网络资源X2已经分别被AP5的相邻无线接入网节点AP2和AP3使用，因此无线接入网节点AP5不能选择网络资源X1和X2，这里假设无线接入网节点AP5选择了网络资源X3，即AP5使用网络资源X3在无线回程链路400-6和无线回程链路400-7上分别与AP2和AP3通信，且AP5采用时分复用方式使用所述网络资源X1在400-6和400-7上分别与AP2和AP3通信。无线接入网节点AP5广播其资源信息，即所述从AP2/AP3获取的网络资源集{网络资源X1，网络资源X2，……网络资源X5}和其选择的所述网络资源X3。
无线接入网节点AP6搜索预定范围内的相邻无线接入网节点，接收所能搜索到的每个相邻无线接入网节点广播的资源信息1。根据表格1可知，无线接入网节点AP6预定范围内有3个相邻无线接入网节点AP3、AP5及AP7。无线接入网节点AP6接收相邻无线接入网节点AP3、AP5及AP7广播的资源信息1，同理，无线接入网节点AP3广播的资源信息1为网络资源集和其所选择的网络资源X2，无线接入网节点AP5广播的资源信息1为网络资源集{网络资源X1，网络资源X2，……网络资源X5}和其所选择的网络资源X3，无线接入网节点AP7尚未广播资源信息1。无线接入网节点AP6选择所要使用的网络资源，网络资源X2和网络资源X3已经分别被无线接入网节点AP6的相邻无线接入网节点AP3和AP5使用，因此无线接入网节点AP6不能选择网络资源X2和X3，这里假设无线接入网节点AP6选择了网络资源X1，即AP6使用网络资源X1在无线回程链路400-8和无线回程链路400-9上分别与AP5和AP3通信，且AP6采用时分复用方式使用所述网络资源X1在400-8和400-9上分别与AP5和AP3通信。无线接入网节点AP6广播其资 源信息，即所述从AP3/AP5获取的网络资源集{网络资源X1，网络资源X2，……网络资源X5}和其选择的所述网络资源X1。
无线接入网节点AP7搜索预定范围内的相邻无线接入网节点，接收所能搜索到的每个相邻无线接入网节点广播的资源信息1。根据表格1可知，无线接入网节点AP7预定范围内有3个相邻无线接入网节点AP3、AP4及AP6。无线接入网节点AP7接收相邻无线接入网节点AP3、AP4及AP6广播的资源信息1，同理，无线接入网节点AP3广播的资源信息1为网络资源集和其所选择的网络资源X2；无线接入网节点AP4广播的资源信息1为网络资源集{网络资源X1，网络资源X2，……网络资源X5}和其所选择的网络资源X1；无线接入网节点AP6广播的资源信息1为网络资源集{网络资源X1，网络资源X2，……网络资源X5}和其所选择的网络资源X1。无线接入网节点AP7选择所要使用的网络资源，网络资源X1和网络资源X2已经分别被AP7的相邻无线接入网节点AP4/AP6和AP3使用，因此无线接入网节点AP7不能选择网络资源X1和X2，这里假设无线接入网节点AP7选择了网络资源X3，即AP7使用网络资源X3在无线回程链路400-10、无线回程链路400-11和无线回程链路400-12上分别与AP3、AP6和AP4通信通信，且AP7采用时分复用方式使用所述网络资源X3在400-10、400-11和400-12上分别与AP3、AP6和AP4通信。无线接入网节点AP7广播其资源信息，即所述从AP3/AP4/AP6获取的网络资源集{网络资源X1，网络资源X2，……网络资源X5}和其选择的所述网络资源X3。
本实施例中每个无线接入网节点AP的广播，具体到长期演进(Long Term Evolution，LTE)系统中，可以是无线资源控制(Radio Resource Control)层发送的系统消息，也可以是新设计的媒体接入控制(Media Access Contrl，MAC)层周期性发送的信息。
采用本实施例的实施方法，无线接入网节点接收预定范围内每个相邻无线接入网节点广播的资源信息1，包括网络资源集和所选择的网络资源，然后该无线接入网节点选择所要使用的网络资源并广播所述从预定范围内相邻无线接入网节点处接收的网络资源集和所述选择的网络资源，使得如图4所示的UDN网络中每个无线接入网节点均能获取所述UDN网络所能使用的网 络资源的集合，而每个无线接入网节点之间又通过监听并接收预定范围内每个相邻无线接入网节点所选择使用的网络资源，从网络资源集中选择未被预定范围内每个相邻无线接入网节点使用的网络资源，有效避免了预定范围内每个无线接入网节点之间的干扰。
实施例二
继续以图4的超密集网络接入网网络拓扑示意图为例，图7给出了本发明实施例二提供的超密集网络的网络资源的配置方法的实施流程图，包括：
S701：资源协调中心可接入节点AP1从资源协调中心480处获得网络资源集，并广播所述网络资源集和AP1的第二相邻无线接入网节点列表。
资源协调中心可接入节点AP1获取网络资源集的行为以及网络资源集和网络资源的描述同实施例一步骤S501，同样，本实施例以无线回程链路的资源使用为例，但也同样适用于无线接入链路的资源使用。网络资源集为{网络资源X1，网络资源X2，……网络资源X5}。
根据表格1可知，资源协调中心可接入节点AP1预定范围内有3个相邻无线接入网节点，分别为无线接入网节点AP2、AP3及AP4，故资源协调中心可接入节点AP1广播网络资源集和其相邻无线接入网节点列表，该列表包含无线接入网节点AP2、AP3及AP4的信息，无线接入网节点AP2、AP3及AP4的信息可以是节点的标识信息，如果每个节点对应一个唯一的小区的话，也可以是小区的标识信息。资源协调中心可接入节点AP1搜索预定范围内的相邻无线接入网节点AP2、AP3及AP4并获取其信息(如标识信息)的过程，可以在资源协调中心可接入节点AP1广播所述信息前的任何时间点完成。
S702：其他无线接入网节点接收预定范围内每个相邻无线接入网节点广播的资源信息2；选择所要使用的网络资源；并广播其资源信息。以其中某一个无线接入网节点X接收预定范围内的相邻无线接入网节点Y为例，资源信息2包括网络资源集，无线接入网节点Y使用的网络资源，无线接入网节点Y的第一相邻无线接入网节点列表和无线接入网节点Y的第二相邻无线接 入网节点列表；无线接入网节点选择完所有使用的网络资源后，其广播的资源信息包括网络资源集，无线接入网节点X使用的网络资源，无线接入网节点X的第一相邻无线接入网节点列表和无线接入网节点X的第二相邻无线接入网节点列表。可选地，上述S702包括三个子步骤：
子步骤1：其他无线接入网节点接收预定区域内每个相邻无线接入网节点广播的资源信息2；
子步骤2：其他无线接入网节点选择所要使用的网络资源；
子步骤3：其他无线接入网节点广播其资源信息；
这里，以无线接入网节点Y为例，第一相邻无线接入网节点，是指Y的预定范围内所有的相邻无线接入网节点中，已经完成网络资源选择并广播了所述选择的网络资源的相邻无线接入网节点。第二相邻无线接入网节点，是指Y的预定范围内所有的相邻无线接入网节点中除去第一相邻无线接入网节点的节点，也即未完成网络资源选择的相邻无线接入网节点。Y的第一相邻无线接入网节点列表包含了Y的所有第一相邻无线接入网节点的信息，Y的第二相邻无线接入网节点列表包含了Y的所有第二相邻无线接入网节点的信息。需要说明的是，对于资源协调中心可接入节点，由于资源协调中心可接入节点可以通过有线接口接入资源协调中心，也可以通过有线接口接入网络，比如接入网络中的服务网关、数据网关等，因此资源协调中心可接入节点自身无需配置无线回程链路，也无需选择网络资源用于回程链路，本实施例中，认为资源协调中心可接入节点为其他可搜索到该资源协调中心可接入节点的无线接入网节点的第一相邻无线接入网节点。
子步骤2中，选择网络资源的过程包括两个步骤，以无线接入网节点X为例，无线接入网节点X选择所要使用的网络资源，包括，
步骤a、无线接入网节点X遍历自己的第一相邻无线接入网节点列表中每一个第一相邻无线接入网节点的第二相邻无线接入网节点列表，找出其中已经选择了网络资源且非该无线接入网节点X的相邻无线接入网节点的无线接入网节点(称为隐藏节点)；
步骤b无线接入网节点X从网络资源集中选择未被其第一相邻无线接入 网节点列表中的每个第一相邻无线接入网节点使用的，也未被步骤a中找到的隐藏节点使用的网络资源，或者选择虽然被无线接入网节点X的第一相邻无线接入网节点列表中的第一相邻无线接入网节点使用的或被步骤a中找到的隐藏节点使用的，但允许多个无线接入网节点共享使用的网络资源。本实施例实施过程中，假设网络资源集中的所有网络资源，都不允许多个无线接入网节点共享使用。
本实施例中，以图4的UDN接入网网络拓扑示意图为例，假设该UDN网络中，每个无线接入网节点AP开启后即发送各自的小区发现信号，因此每个AP开启后均能相互检测到相邻的无线接入网节点AP。然而每个无线接入网节点AP需要等待资源协调中心可接入节点AP1从资源协调中心480处获取到网络资源集合后，才能开始网络资源的选择过程，这里假设图中每个无线接入网节点AP实际选择网络资源的顺序为AP2-AP3-AP4-AP5-AP6-AP7，则每个无线接入网节点AP的第一相邻无线接入网节点列表，第二相邻无线接入网节点列表以及每个无线接入网节点AP从其第一相邻无线接入网节点列表中的每个第一相邻无线接入网节点的第二相邻无线接入网节点列表中遍历出来的隐藏节点如表格2所示。

表格2
根据表格2，每个无线接入网节点AP监听预定范围内每个相邻无线接入网节点广播的资源信息2，选择无线接入网节点AP所要使用的网络资源并广 播资源信息的过程为：
无线接入网节点AP2搜索预定范围内的相邻无线接入网节点，接收所能搜索到的每个相邻无线接入网节点广播的资源信息2，具体行为同步骤S502的描述。根据表格2可知，无线接入网节点AP2预定范围内有1个第一相邻无线接入网节点，为资源协调中心可接入节点AP1，2个第二相邻无线接入网节点AP3和AP5，无线接入网节点AP2接收AP1、AP3和AP5广播的资源信息2，可选的，接收的资源信息2是指AP1、AP3和AP5广播的网络资源集，以及如果AP1、AP3和AP5广播的话，接收AP1、AP3和AP5广播的三者各自选择的网络资源以及其广播的各自的第一相邻无线接入网节点列表和第二相邻无线接入网节点列表。其中，对于资源协调中心可接入节点AP1，可以通过有线接口401接入资源协调中心，也可以通过有线接口接入网络，比如接入网络中的服务网关、数据网关等(图4中未示出)，因此资源协调中心可接入节点AP1自身无需配置无线回程链路，根据本实施例每个无线接入网节点AP的资源选择顺序，资源协调中心可接入节点AP1也不存在第一相邻无线接入网列表，故资源协调中心可接入节点AP1不需要广播其选择的网络资源也无需广播其第一相邻无线接入网节点列表，因此无线接入网节点AP2从资源协调中心可接入节点AP1接收到的资源信息2只包括网络资源集{网络资源X1，网络资源X2，……网络资源X5}和资源协调中心可接入节点AP1的第二相邻无线接入网节点列表(即步骤S701中资源协调中心可接入节点AP1广播的信息)。根据本实施例假设的每个无线接入网节点AP实际选择网络资源的顺序，无线接入网节点AP3和AP5在AP2之后选择网络资源，因此，在无线接入网节点AP2接收预定区域内每个相邻无线接入网节点的广播，选择确定所要使用的网络资源并广播网络资源集和所选择的网络资源之前，其第二相邻无线接入网节点列表中的节点AP3和AP5不广播资源信息2，也即本发明实施例规定，除了资源可接入节点AP1之外，其他无线接入网节点只有在确定了资源信息2中的所有信息后才广播资源信息2，因此对于某个无线接入网节点而言，接收该无线接入网节点所能搜索到的每个相邻无线接入网节点广播的资源信息2，是指接收该无线接入网节点的第一相邻无线接入网节点列表中的每个第一无线接入网节点所广播的其资源信息2。
无线接入网节点AP2选择所要使用的网络资源，包括，无线接入网节点AP2遍历自己的第一相邻无线接入网节点AP1的第二相邻无线接入网节点列表AP2，AP3，AP4，未找到隐藏节点(无线接入网节点AP3为AP可以搜索到的相邻节点，AP4尚未选择网络资源)。无线接入网节点AP2从网络资源集中选择未被AP2的第一相邻无线接入网节点列表中的节点(AP1)使用的网络资源，本实施例假设AP2选择了网络资源X1，即AP2使用网络资源X1在无线回程链路400-1上与AP1通信。
