具体实施方式
在下文中将结合附图对本公开的示范性实施例进行描述。为了清楚和 简明起见， 在说明书中并未描述实际实施方式的所有特征。 然而， 应该了 解，在开发任何这种实际实施例的过程中必须做出 艮多特定于实施方式的 决定， 以便实现开发人员的具体目标， 例如， 符合与系统及业务相关的那 些限制条件， 并且这些限制条件可能会随着实施方式的不同而有所改变。 此外， 还应该了解， 虽然开发工作有可能是非常复杂和费时的， 但对得益 于 开内容的本领域技术人员来说， 这种开发工作仅仅是例行的任务。
在此，还需要说明的一点是，为了避免因不必要的细节而模糊了本公 开， 在附图中仅仅示出了与根据本公开的方案密切相关的设备结构和 /或 处理步骤， 而省略了与本公开关系不大的其它细节。
首先，将参照图 1描述无线通信系统中的网络架构的示例，并同时给 出了本发明中提出的一些概念的简要介绍。图 1是示出无线通信系统中多 种组网模式共存的场景的示意图。
如图 1所示， 根据接入方式和功能， 用户设备可以进一步被划分为： a) 网络用户设备（Network User Equipment, nUE ): 通过直接为其 服务的^ ί设施接入网络并通过该^？设施进行通信，例如， ιιϋΕΙ 和 nUE2。
b)主用户设备（Master User Equipment, mUE ): 具有为其它网络节 点转发数据和 /或信令的功能。 例如， mUEl在 MBS与 sUEl之间 进行数据转发， 构成中继网络 ( Relay Network ); mUE2在 SBS与 sUE2之间进行数据转发； mUE3与 sUE3、 sUE4和 sUE5组成 PMP 互连， 其中， mUE3负责其它用户设备间的数据转发， 并且 mUE3 与 MBS维持无线信令链路以便维护该 PMP互连； mUE4与 sUE6 组成设备到设备 ( Device to Device, D2D )互连， mUE4与 sUE6 之间直接进行数据交换， 但是 mUE4与 MBS维持无线信 路以 便维护该 D2D互连。
c) 从用户设备（Slave User Equipment, sUE ): 需要由主用户设备进 行数据转发而与其它网络节点进行通信，如上述 sUEl至 sUE5，或 者与其它用户设备组成 D2D互连且由对方用户设备负责与基础设 施维持无线信令链路以便维护该 D2D互连， 如上述 sUE6。
应理解， 任何一个用户设备可以同时具有多重身份， 例如， mUEl 直接和 MBS进行数据连接以获得^ δ¾设施提供的通信服务时作为网络用 户设备， 而当其承担在 MBS和 sUEl之间进行数据转发时作为主用户设 备。
从图 1可以看出， 在该无线通信系统中， 包括中继网络、 D2D互连 以及 PMP互连等的多种组网模式共存， 从而需要根据网络运营状况、 用 户设备的需求、处理能力及其职能的变化而进行动态网络规划， 以保证较 高的网络容量和用户设备之间的公平性。
接下来，将参照图 2描述根据本公开的实施例的无线通信系统中的装 置的功能配置的示例。图 2是示出根据 开的实施例的无线通信系统中 的装置的功能配置示例的框图。
如图 2所示，无线通信系统中的装置 200可包括用户设备参数获取单 元 202、 主用户设备确定单元 204和通信单元 206。
用户设备参数获取单元 202 可被配置成从用户设备获取用户设备参 数。
应指出， 这里所述的用户设备参数表示进行动态网络规划所需的参 数。 因此， 除了传统的通信网络链路建立所需的业务需求^：、服务质量 ( Quality of Service, QoS )参数以及链路质量测量和反馈相关参数之外， 用户设备参数还可包括但不限于用户设备的位置信息和用户设备发出的 组网请求信令等等。
用户设备的位置信息可以是表示用户设备的绝对位置的经度和締度 值，也可以是表示用户设备在预定坐标系内的相对位置的坐标值，本公开 对此不作限制。 位置信息可以通过借助于全球定位系统 （ Global Positioning System, GPS )传感器进行 GPS测量来获得， 也可以通过网 络测量（例如三角测量）来获得。 装置 200可以在需要位置信息时向用户 设备发起位置信息请求或者发起网络测量， 以获得反馈结果。
组网请求信令提供了在不同组网模式之间进行选择和切换的机制，用 户设备可以通过向装置 200发送组网请求信令而选择不同的组网模式，从 而实现网络结构的动态调整以提高网络资源利用率。作为示例， 以下将参 照图 3A来描述组网请求信令的格式的示例。 图 3A是示出根据 开的 实施例的用户设备 4*中包括的组网请求信令的格式示例的示意图。
如图 3A所示， 组网请求信令包括四个子域， 即， 信令类型、 用户设 备标识符（ Identifier, ID ), 组网模式以及选择模式。 下面将分别详细描 述各个子域所表示的含义。
具体地， 信令类型标识该信令为组网请求信令。 用户设备 ID标识发起该信令的用户设备， 这是分配给该用户设备的 全网唯一标识符。
组网模式标识用户设备接入网络的方式， 可包括"仅通过 设施接 入"、 "可通过其它用户设备接入 "以及 "用户设备互连"，其中缺省值为 "仅 通过^ 5*设施接入"， 这是为了与原无线通信网络系统兼容。 当组网模式 为 "仅通过基础设施接入"或缺省时，表示用户设省^支持通过^ δ¾设施接 入网络； 当组网模式为 "可通过其它用户设备接入 "时，表示用户设备支持 利用主用户设备在 ^设施与从用户设备间进行数据转发的组网模式，并 且该用户设备可以为主用户设备或从用户设备； 而当组网模式为 "用户设 备互连 "时， 表示用户设备希望与其它用户设备建立 D2D互连或 PMP互 连， 并且该用户设备可以为主用户设备或从用户设备。
应理解，对于组网模式为"仅通过基础设施接入"的用户设备，其组网 过程与现有技术中相同， 在此不再讨论。 因此， 以下讨论主要是针对组网 模式为 "可通过其它用户设备接入"和"用户设备互连"的用户设备。
选择模式可包括"网络分配 "和"用户强制指定，，， 其中缺省值为 "网络 分配"。 当选择模式为 "网络分配"或缺省值时， 表示用户设备支持由例如 装置 200发布的组网决策结果； 而当选择模式为"用户强制指定 "时，表示 用户设备指定自己和相关网络节点的关联关系， 即，用户设备指定自己是 作为主用户设备还是从用户设备。 以下讨论主要针对选择模式为 "网络分 配" 的情况。
特别地，对于组网模式为"用户设备互连，，的用户设备，希望加入同一 互连的用户设备需要向装置 200发送用户设备互连请求信令。 同样，对于 组网模式为 "可通过其它用户设备接入"的用户设备， 它们希望通过其中 某个用户设备作为中继节点接入基础设施的用户设备组， 需要向装置 200 发送用户设备互连请求信令。 图 3B是示出用户设备互连请求信令的格式 示例的示意图。
如图 3B所示， 用户设备互连请求信令可包括三个子域， 即， 信令类 型、 用户设备 ID和用户设备互连 ID。 具体地， 信令类型标识该信令为用 户设备互连请求信令， 用户设备 ID是分配给发出该用户设备互连请求信 令的用户设备的全网唯一标识符， 并且用户设备互连 ID是分配给用户设 备希望加入的互连的全网唯一标识符。
根据用户设备发出的组网请求信令中的组网模式的不同，用户设备参 数获取单元 202可以以不同的方式来获取用户设备参数。
基本上， 对于选择模式为 "网络分配" 的用户设备， 其用户设备参数 获取流程可以如下：用户设备在初始接入网络时或者需要变更组网模式时 向例如装置 200发送组网请求信令，用户设备参数获取单元 202从用户设 备获取包括该组网请求信令的用户设备参数。
而具体地，对于组网模式为"用户设备互连 "或者 "可通过其它用户设 备接入"，且具有对连接对象的期望的用户设备，根据选择模式为"网络分 配"还是"用户强制指定"， 其用户设备参数获取流程如下：
• 当选择模式为 "网络分配"时， 首先由一个用户设备向装置 200发送 组网请求信令， 该用户设备仅为临时主用户设备（即仅用于发起用 户设备互连时使用， 区别于互连建立后负责实际数据转发的主用户 设备）， 装置 200为该互连分配一个全网唯一的"用户设备互连 ID" 并发送给该临时主用户设备。 该临时主用户设备将收到的 "用户设 备互连 ID"发布给其他希望加入该互连的用户设备， 例如， 通过线 下的人际交互方式发布或者通过广播的方式发布。 其它希望加入该 互连的用户设备获得该 "用户设备互连 ID"后向装置 200发送包含 该"用户设备互连 ID"的用户设备互连请求信令（参见图 3B ),从而 用户设备参数获取单元 202从这些用户设备获取包括该用户设备互 连请求信令的用户设备参数， 并且装置 200将这些用户设备作为一 组互连对象以进行后续组网操作。
当选择模式为 "用户强制指定"时， 首先由一个用户设备向装置 200 发送组网请求信令， 该用户设备即被强制指定为主用户设备， 装置 200 为该互连分配一个全网唯一的"用户设备互连 ID，，， 其它希望加入该互连 的用户设备向装置 200发送包含该"用户设备互连 ID"的用户设备互连请 求信令（参见图 3B )， 从而用户设备 获取单元 202从这些用户设备获 取包括该用户设备互连请求信令的用户设备参数，并且装置 200将这些设 为该互连中的从用户设备。对于组网模式为"用户设备互连 "的用户设 备接着直接建立网络连接即可。 对于组网模式为 "可通过其他用户设备接 入"的用户设备， 装置 200接着为主用户设备选取最佳直接服务的基础设 施，最后建立由主用户设备在羞^设施和从用户设备之间进行数据转发的 中继网络。
返回参照图 2， 主用户设备确定单元 204可被配置成根据基于用户设 备参数而确定的用户设备接近通信数据流中心的程度来确定主用户设备， 其中，主用户设备连接到相关联的基础设施并且具有为其它用户设备转发 数据和 /或信令的功能。
应理解， 对于 D2D互连和 /或 PMP互连， 由于主用户设备主要与从 用户设备进行数据转发而与 设施间的信令交互较少，因此通信数据流 中心表示处于该位置的用户设备能够为其它组网用户设备提供最优的公 平信道质量， 而对于中继网络， 由于主用户设备和^ δ¾设施之间的链路不 仅负责传输主用户设备的数据还要转发从用户设备的数据，因此其通信数 据流中心表示处于该位置的用户设备能够在基础设施与其它组网用户设 备之间提供最优的公平数据转发。应理解，通信数据流中心不同于实际的 地理位置中心， 其与信道盾量、 各网络节点 （包括基础设施和用户设备） 间的链路的通信载荷以及各个网络节点的地理位置等有关。
因此，主用户设备确定单元 204可根据所获取的用户设备参数，优先 选择最接近上述通信数据流中心的用户设备作为主用户设备。
下面将参照图 4来详细描述主用户设备确定单元 204的功能配置的示 例。图 4是示出图 2所示的装置中的主用户设备确定单元的功能配置示例 的框图。
如图 4所示，主用户设备确定单元 204可进一步包括分布特征参数获 W¾块 402和主用户设备选择模块 404。
分布特征参数获取模块 402可被配置成根据所获取的用户设备参数， 获取表示所述用户设备接近通信数据流中心的程度的分布特征参数。
主用户设备选择模块 404可被配置成根据所获取的分布特征参数来 选择主用户设备。
下面将参照图 5来详细描述分布特征参数获取模块 402的功能配置的 示例。图 5是示出图 4所示的主用户设备确定单元中的分布特征参数获取 模块的功能配置示例的框图。
如图 5所示，分布特征参数获取模块 402可进一步包括用户设备分组 部件 502、 候选主用户设备确定部件 504和分布特征参数计算部件 506。
用户设备分组部件 502 可被配置成根据用户设备参数中的组网模式 对用户设备进行分组。
优选地，用户设备分组部件 502可进一步被配置成将组网模式参数表 示"用户设备互连"（即建立 D2D互连和 /或 PMP互连）划分为第一类型 组，将组网模式参数表示 "可通过其它用户设备接入"的用户设备划分为第 二类型组，并且将组网模式参数表示 "仅通过羞^设施接入"的用户设备划 分为第三类型组。其中，对于第一类型组或第二类型组还可以¾1据用户设 备互连 ID进一步进行划分， 例如将第一类型组或第二类型组中具有相同 用户设备互连 ID的用户设备划分为一组。
优选地，对于第二类型组中不具有用户设备互连 ID参数的用户设备， 还可根据区域分布而对其进一步进行划分，这是由于考虑到当用于进行数 据转发的主用户设备到基础设施和从用户设备的链路优于从基础设施到 从用户设备的直接链路时，这种转发才有可能提高网络吞吐量， 而链路质 量与网络节点间的距离有关，因此当所确定的主用户设备距从用户设备过 远时， 这种转发就失去了意义。
鉴于此，优选地，用户设备分组部件 502可进一步被配置成根据区域 分布而将^ δ¾设施的覆盖范围划分为多个扇区，从而每个扇区内的用户设 备被划分成一组。应理解， 为了保证链路盾量， 主用户设备仅为同一扇区 内的从用户设备提供数据转发。作为示例， 用户设备分组部件 502可釆用 本领域中常用的三扇区划分法而将基础设施的覆盖范围等分为三个扇区。
图 6是示出根据本公开的实施例的用户设备分组结果的示例的示意 图。如图 6所示，宏基站 MBS覆盖的宏小区和小基站 SBS覆盖的小小区 分别被划分为三个扇区。
此外， 应理解， 上述分组操作并非在物理上对用户设备进行分组， 上 述第一类型组、 第二类型组和第三类型组仅为虚拟进行划分的概念。
候选主用户设备确定部件 504可被配置成根据所划分的每组用户设 备中的每个用户设备与其相关联的基础设施之间的链路质量来确定该组 中的候选主用户设备集合。
具体地， 在第一类型组中， 对于具有相同"用户设备互连 ID"的组， 将组建以其中某个节点作为主用户设备的 D2D或 PMP网络，该主用户设 备和其它从用户设备进行数据交换，或者负责为其它从用户设备进行数据 转发， 同时还要和基础设施保持良好的信令链路以维护该互连。在第二类 型组中， 将组建^ δ¾设施和主 /从用户设备间的中继网络， 主用户设备和 设施之间的链路不仅用来为该主用户设备自身提供通信，还要为从用 户设备转发数据， 所以更要保证较高的链路质量。 因此， 成为主用户设备 的先决条件是具有到基础设施的良好链路质量。 作为示例，优选地，候选主用户设备确定部件 504可通过以下方式来 确定第一 /第二类型组中的候选主用户设备集合： 为每个用户设备选择其 所在区域内信道盾量最好的基础设施， 从而具有相同"用户设备互连 ID" 的用户设备以及与这些用户设备相关联的基础设施被划分为一组，而没有
"用户设备互连 ID" 处于同一区域内且与同一^ eij设施相关联的 用户设备被划分为一组，然后将各个组内与相关联的基础设施之间的信道 质量等于或高于预定信道质量阈值的用户设备加入候选主用户设备集合 中。
分布特征参数计算部件 506可被配置成根据每组的候选主用户设备 集合中的每个候选主用户设备与相关联的其它用户设备和基础设施之间 的位置信息， 计算该组中的每个候选主用户设备的分布特征参数。
具体地，对于第一类型组，分布特征参数计算部件 506可被配置成根 据每个候选主用户设备与该组中的所有其它用户设备和与该候选主用户 设备相关联的基础设施之间的距离来计算该候选主用户设备的分布特征 而对于第二类型组，分布特征参数计算部件 506可被配置成根据每个 候选主用户设备与该组中除候选主用户设备集合之外的用户设备和与该 候选主用户设备相关联的基础设施之间的距离来计算该候选主用户设备 的分布特征参数。
如上所述， 由于主用户设备通常是最靠近通信数据流中心的用户设 备，因此用户设备的分布特征参数计算还应将与该用户设备相关联的通信 链路的传输负荷纳入考虑。优选地，分布特征参数计算部件 506还可被配 置成根据与每组的候选主用户设备集合中的每个候选主用户设备相关联 的通信链路的传输负荷来计算该候选主用户设备的分布特征参数。
下面将作为示例给出分布特征 计算的具体过程。
作为示例，衡量用户设备的分布特征参数的一个指标为加权接近中心 性， 其可由以下等式来表示：
其中， WCC(UEi)表示候选主用户设备 UEi的加权接近中心性； n表示参 与该计算公式的节点总数， 包括涉及到的用户设备、基站， 以及被考察的 候选主用户设备自己； distanceOJEi, UEj)表示候选主用户设备 UEi与网络 节点 UEj之间的距离， 该距离可根据各个网络节点的位置信息而得到； ft 是为网络节点 UEj分配的权重，其可以由候选主用户设备 UEi与网络节点 UEj之间的链路的通信载荷来确定。 应理解， 加权接近中心性的值越小， 则说明用户设备越接近通信数据流的中心， 即，该用户设备越适合于被选 作主用户设备。
根据以上描述可知，在第一类型组中， 由于主用户设备的选择依据是 尽可能保证各从用户设备获得最优的公平的信 量，因此当计算加权中 心性时， 需要考虑每个候选主用户设备 UEi与组内的所有其它用户设备 (包括其它候选主用户设备以及除候选主用户设备集合之外的用户设备 ) 以及相关联的^ ί设施之间的距离和通信载荷。应理解， 当组内存在多个 设施时， 仅考虑与当前所考察的候选主用户设备相关联的基础设施。 此外，在第一类型组中， 由于主用户设备主要和从用户设备之间进行数据 转发而与基础设施之间的信令交互较少， 因此为了简化计算， 权重 ft的 设定可以假设例如为： 如果网络节点 UEj是 设施， 则权重 β』被设置 为 1/η， 否则权重 β』被设置为 1。
另一方面，在第二类型组中， 由于主用户设备的选择依据是尽可能在 设施和从用户设备之间提供最优的公平的数据转发，因此当计算加权 接近中心性时，需要考虑每个候选主用户设备 UEi与组内除候选主用户设 备集合之夕卜的用户设备和基础设施之间的距离和通信载荷。在第二类型组 中，由于主用户设备和羞^设施之间的链路不但负责传输主用户设备的数 据还要转发从用户设备的数据， 因此为了简化计算， 权重 ft的设定可以 假设例如为： 如果网络节点 UEj是^ ^设施， 则权重 β』被设置为 n， 否则 权重 被设置为 1。
应理解， 以上给出的计算加权中心性的方式仅为示例而非限制，并且 本领域技术人员可以根据本公开的原理而对上述计算方式进行修改。
此外，作为示例，还给出了另一种用于衡量用户设备的分布特征参数 的指标， 即， 有效链路计量图中具有最大相邻边权和的顶点。 具体地， 对 于候选主用户设备，以例如组内与该候选主用户设备相关联的成员节点间 的距离的最大值和最小值的平均值作为距离阈值 Dth， 然后以该候选主用 户设备和这些成员节点作为顶点，若两个顶点对应的网络节点间的距离小 于距离阈值 Dth， 则在这两个顶点间连一条边并且为该边设定权重 γ 从 而得到关于该候选主用户设备的有效链路计量图。以该候选主用户设备对 应的顶点相连的边的权重之和作为衡量指标，边权重之和越大，说明该候 选主用户设备越接近通信数据流的中心，从而越适合用作该组内的主用户 设备。 应指出， 对于第一 /第二类型组， 与每个候选主用户设备相关联的 成员节点的选择以及边权重 η的设置与以上计算加权接近中心性时设定 权重 Pj的规则相同， 在此不再赘述。
应理解， 以上给出的建立有效链路计量图的方式仅为示例而非 P艮制， 例如， 距离阈值 Dth可以为节点间的最小距离值或者用户预先设定的距离 值等等。
此外，还应理解，尽管以上给出了两种用于计算用户设备的分布特征 参数的方式，但这仅为示例而非 P艮制，并且本领域技术人员可以采用任意 其它方式来计算分布特征参数，只要这些方式落入本发明的原理的范围内 即可。
下面将参照图 7描述主用户设备确定单元 204的另一功能配置的示 例。图 7是示出图 2所示的装置中的主用户设备确定单元的另一功能配置 示例的框图。
如图 7所示，主用户设备确定单元 204可包括分布特征参数获取模块 702、 转发特征参数计算模块 704和主用户设备选择模块 706。 其中， 分 布特征参数获取模块 702的功能配置与以上参照图 4至图 6描述的分布特 征参数获取模块 402的功能配置相同，在此不再重复描述其细节。 以下将 详细描述转发特征参数计算模块 704和主用户设备选择模块 706的功能配 置的示例。
优选地，上述用户设备参数获取单元 202从用户设备获取的用户设备 还可包括用户设备的数据和信令转发量、表示用户设备成功进行转发 的转发概率和表示用户设备的转发能力的转发级别等等。
具体地， 用户设备 UEi的数据和信令转发量 di可例如被定义为该用 户设备在预定时段内的平均转发量。
转发概率 表示用户设备 UEi成功进行转发的概率， 其是数据和信 令转发量的衍生参数，并且可通过例如以下方式来设置：对于任意用户设 备， 若其对数据和信令的转发量大于预定的转发量阈值 dth， 则对该用户 设备进行奖励， 即， 增大该用户设备的转发概率； 相反则对该用户设备进 行惩罚， 即， 减小该用户设备的转发概率。 也就是说， 对于承担转发任务 较多的用户设备，其在通信服务中也可优先获得转发服务，这有利地促进 了用户设备在空闲时主动 数据转发任务的意愿，有利于资源的合理配 置。
假设每个用户设备 UEi的转发量 di和转发概率 pi的初始值均为 0，随 着网络状态的变化， 每隔预定时间 T统计每个用户设备新的转发量 di，并 同时更新转发概率 Pi，， 具体更新方法例如可以为： 以所划分的组为单位 进行考虑， 假设变更速度（即， 调整转发概率的速度）为 δ， 用户设备总 数为 nUE，转发量超过预定阈值从而被奖励的用户设备数为 nre，则被惩罚 的用户设备数为 nUE-nre， 从而对于被奖励的用户设备， 其更新后的转发 概率 Pi '= min{pi +-^-,1}， 并且对于被惩罚的用户设备， 其更新后的转发概率 ,0}。

用户设备 UEi的转发级别 表示该用户设备进行转发的能力，其可例 如由该用户设备的数据处理能力、 电量等因素综合确定，并可被量化为多 个级别。作为示例， 转发级别的一种定义方法可以为级别越低， 则转发能 力越强。
应理解， 以上给出的用户设备的转发量、转发概率和转发级别的计算 方法仅为示例而非限制，并且本领域技术人员可根据本公开的原理而采用 其它方式进行计算。
因此，转发特征参数计算模块 704可被配置成根据用户设备的数据和 信令转发量、表示用户设备成功进行转发的转发概率和表示用户设备的转 发能力的转发级别中的至少一个来计算用户设备的转发特征参数。 优选 地，转发特征参数计算模块 704还可被配置成基于上述分组后的用户设备 来计算每组中的用户设备的转发特征参数。
可以理解，转发特征^：的引入保证了用户设备在提供和获得转发服 务中的公平性，其考虑了用户设备的职能差异化，有利地促进了用户设备 承担数据转发的意愿， 从而有助于提高网络容量。
主用户设备选择模块 706优选地可被配置成根据分布特征参数获取 模块 702获取的分布特征参数和转发特征参数计算模块 704计算的转发特 征^ t来选择主用户设备。
主用户设备选择模块 706可根据不同的网络性能优化目标而选择主 用户设备。 具体地， 如果以网络容量最大化为优化目标， 则主用户设备选 择模块 706可根据分布特征参数来选择主用户设备，例如，按照加权接近 中心性从小到大进行选择，或者按照有效链路计量图的相邻边权和从大到 小进行选择； 如果以用户公平性最大化为优化目标， 则可根据转发特征参 数来选择主用户设备，例如，按照转发概率或者按照转发级别从小到大进 行选择； 并且如果同时兼顾网络容量和用户公平性， 则综合考虑分布特征 ^ t和转发特征参数，例如，可按照加权接近中心性与转发概率的乘积从 小到大进行选择。
所选择的主用户设备的数量可根据网络性能优化目标和组网模式需 求来确定。在本公开的实施例中，对于每组用户设备仅选择一个主用户设 备，该主用户设备负责组内的其它用户设备之间以及其它用户设备与^ ¾ 设施之间的通信。
从上述可以看出，由于主用户设备选择模块 706在选择主用户设备时 可兼顾网络容量和用户公平性，从而能够提高用户设备作为^设施补充 这一概念的实用性， 并且提高了资源利用率。
返回参照图 2， 通信单元 206可被配置成向用户设备发送包括所确定 的主用户设备的信息的组网控制信令。组网控制信令可用于确定网络的无 线链路的构成， 即，确定各个用户设备之间以及与基础设施之间进行通信 的路由。
下面将参照图 8描述根据本公开的另一实施例的无线通信系统中的 装置的功能配置的示例。图 8是是示出根据本公开的另一实施例的无线通 信系统中的装置的功能配置示例的框图。
如图 8所示， 装置 800可包括用户设备参数获取单元 802、 主用户设 备确定单元 804、 从用户设备确定单元 806和通信单元 808。 其中， 用户 设备参数获取单元 802和主用户设备确定单元 804的功能配置分别与以上 参照图 2至 7描述的用户设备参数获取单元 202和主用户设备确定单元 204的功能配置相同， 在此不再描述其细节。 下面将分别详细描述从用户 设备确定单元 806和通信单元 808的功能配置的示例。
从用户设备确定单元 806可被配置成至少根据上述转发特征参数，选 择与所确定的主用户设备相关联的从用户设备，其中，从用户设备通过相 关联的主用户设备与其它用户设备和^ δ¾设施进行通信。
具体地， 对于分组后的每组用户设备， 在主用户设备确定单元 804 确定了该组中的主用户设备之后，对于属于第一类型组的用户设备，该组 内的其它用户设备都被选择作为从用户设备。
而对于属于第二类型组的用户设备，在主用户设备确定单元 804确定 了该组中的主用户设备之后，从用户设备确定单元 806可通过以下方式来 确定从用户设备：测量该组中除主用户设备之外的每个用户设备到主用户 设备的链路盾量，如果该链路质量低于该用户设备直接连接到基础设施的 链路质量， 则确定这些用户设备直接通过基础设施接入网络； 否则， 对于 剩余的用户设备，如果以网络性能为优化目标，则按照到主用户设备的链 路盾量从高到低进行选择； 如果以用户公平性为优化目标， 则按照转发概 率从大到小选择相关联的从用户设备；如果同时兼顾网络性能和用户公平 性， 则综合考虑信道质量和转发特征参数， 例如， 可按照信道质量与转发 概率的乘积从大到小进行选择； 并且如果以网络容量最大为优化目标，则 可根据每个用户设备通过主用户设备接入网络与直接通过基础设施接入 网络相比所导致的网络容量的提升变化量从大到小进行选择。所选择的从 用户设备的数量可根据主用户设备的承载能力而实时计算，或者也可由系 统预设的阈值来确定。
应理解，对于第一类型组和第二类型组中除主用户设备和从用户设备 之外的用户设备以及第三类型组中的用户设备， 可利用现有技术的方法， 根据用户设备到各个基础设施的链路质量以及可用的无线资源而为其选 择最适合的基 设施，从而这些用户设备直接通过所选择的基 设施接入 网络。
以上给出了从用户设备的选择方式的示例，但是应理解，这仅是示例 而非限制，并且本领域技术人员可根据具体的网络性能优化目标来选择从 用户设备。
此后，通信单元 806可被配置成将包括关于主用户设备和从用户设备 的信息的组网控制信令发送给用户设备，从而用户设备可根据所接收的组 网控制信令而完成组网操作。
应理解，这里的组网控制信令可包括要进行组网的用户设备的职能分 配（网络用户设备、 主用户设备或从用户设备）以及用户设备之间和与基 础设施之间的通信路由的选择，从而用户设备可根据所接收的组网控制信 令而选择最佳的通信路由（包括一条或多条无线链路）进行数据通信， 以 增加网络容量， 提高通信质量并提高资源利用率。 尽管以上描述了根据本公开的实施例的动态网络规划的具体实现过 程， 但是应理解， 这仅是示例而非限制， 并且本领域技术人员可根据 开的原理而对上述方案进行修改。例如，对于经常加入同一用户设备互连 的用户设备，例如，在办公室中由于需要频繁进行数据交换而建立的工作 组中的多台个人计算机，或者家庭中共享数据资源的多个终端设备 (诸如， 智能电话、个人数字助理（PDA )、平板电脑、个人计算机等等），优选地， 也可以根据历史信息（即， 这些用户设备的职能分配和通信路由选择）而 确定其组网模式， 从而有利于加速网络分配。
在这里应指出，尽管以上参照图 1至图 8描述了根据本公开的实施例 的无线通信系统中的装置的示例功能配置，但是应理解，这仅是示例而非 P艮制，并且本领域技术人员可以根据需要而对上述结构进行修改，例如增 加或省略某些功能单元，或者对功能单元进行组合，并且这些变型都认为 落在本技术的实质范围内。

另外， 还应该指出的是， 上述系列处理和装置也可以通过软件和 /或 固件实现。 在通过软件和 /或固件实现的情况下， 从存储介质或网络向具 有专用硬件结构的计算机，例如图 16所示的通用个人计算机 1600安装构 成该软件的程序，该计算机在安装有各种程序时，能够执行各种功能等等。
在图 16中， 中央处理单元（CPU ) 1601才艮据只读存储器（ROM ) 1602 中存储的程序或从存储部分 1608加载到随 I ^ 储器（RAM ) 1603的程序执行各种处理。在 RAM 1603中，也才艮据需要存储当 CPU 1601 执行各种处理等等时所需的数据。

还需要指出的是，执行上述系列处理的步骤可以自然地根据说明的顺 序按时间顺序执行，但是并不需要一定根据时间顺序执行。某些步骤可以 并行或彼此独立地执行。 应用示例
应指出， 除了上述移动通信网络之外，根据 开的技术还可用于以 下个人网络的组网管理。无论在家庭娱乐环境还是办公环境中，个人电子 设备持有量逐渐增加， 包括多媒体娱乐设备（诸如电视、 游戏机、 音频 / 视频播放器、 智能手机）、 办公设备（诸如平板电脑、 笔记本电脑、 台式 电脑等）、 存储^ H殳备 (诸如 存储阵列等）、 网^^入设备 (诸如路 由器等）。 个人设备数量的激增给数据的更新和同步带来了巨大的麻烦。 随着云计算技术的成熟，一种逐渐流行起来的方法是将数据在云端进行存 储和处理，个人电子设备不提供本地存储而是利用高速通信链路、通过接 入点和云端进行数据交换。 由于家庭或者办公室的布局往往非常复杂，用 户设备位置又经常发生变动，设备间构成的无线网络的有效性和性能^ 得到保证。 若釆用本发明的方法， 在云端接入点嵌入动态网络规划功能， 并将各设备组网模式参数设为 "可通过其它用户设备接入"， 则可根据各 设备的状态灵活组网， 使得网络性能得到极大的保障。
