需要说明的是, 本文中的 "第一" 、 "第二" 等描述, 是用于区分 不同的消息、设备、模块等, 不代表先后顺序, 也不限定"第一"和"第二" 是不同的类型。 本文中的 "若" , 是表示满足某个条件、 状态, 包括了 "当" 、 "条件满足后" 、 "判断成立" 等含义。 "消息" 是承载若干 信息的载体, 包括信令、 通信信号、 数据消息等多种形式。
本文中的直连通信, 在用户设备之间进行直连通信时, 由某一用户 设备直接将消息发送给另一用户设备, 不需要经过基站或第三方结点的 转发和控制。
用户设备用户设备之间建立通信直连通信连接的方式可以有如下几 种:
如图 1 所示, 提供了用户设备之间建立直连通信的一种方式: 101、 第一用户设备接收发自第二用户设备的发现消息 (discovery message ) ;
该发现消息可以由第二用户设备在信号范围内进行广播, 第一用户 设备可以在第二用户设备的发射信号范围内收到该发现消息。
102、第一用户设备向第二用户设备发送寻呼消息( paging message ); 若第一用户设备被允许与第二用户设备建立直连通信连接, 则根据 收到的发现消息向第二用户设备发送寻呼消息。
103、 第二用户设备向第一用户设备发送寻呼响应消息 (paging response message ) ;
104、 第一用户设备与第二用户设备建立直连通信连接, 进行直连通 信。
如图 2所示, 提供了用户设备之间建立直连通信的又一种方式: 201、第一用户设备向第二用户设备发送寻呼消息( paging message );
202、 第二用户设备向第一用户设备发送寻呼响应消息 (paging response message ) ;
203、 第一用户设备与第二用户设备建立直连通信连接, 进行直连通 信。
在一些特定的情况下, 如第二用户设备对于第一用户设备来说是已 知的, 或者第二用户设备与第一用户设备曾经建立过直连通信连接, 则 相较于上一种建立直连通信的方式来说, 第一用户设备无需接收第二用 户设备发送的发现消息, 即可向第二用户设备发起寻呼消息, 建立直连 通信连接。
如图 3所示, 提供了用户设备之间建立直连通信的又一种方式:
301、 第一用户设备接收发自第二用户设备的发现消息 (discovery message ) ;
302、第一用户设备向第一服务器发送对第二用户设备的直连通信请 求;
303、 第一服务器给第一用户设备分配直连通信资源;
304、 第一服务器给第二用户设备分配直连通信资源; 305、 第一用户设备与第二用户设备根据分配的直连通信资源, 建立 直连通信连接, 进行直连通信。
本方案中, 第一服务器同时服务于第一用户设备和第二用户设备, 并为第一用户设备和第二用户设备分配直连通信资源, 帮助第一用户设 备和第二用户设备建立直连通信连接。 该第一服务器可以是基站设备如 演进型基站( Evolved Node B, eNodeB ) 、 基站收发台 ( Base Transceiver Station, BTS ) 、 服务网关(Serving Gateway, SGW)、 分组网关(Packet Gateway, PGW)、 无线网络控制器 (Radio Network Controller, RNC)等, 也 可以是簇头 Cluster head或 Wi-Fi热点设备等用户设备管理设备。实施例中 的直连通信资源,在时分复用多址***中,可以是时隙资源;在频分复用多 址***中, 可以是频率资源;在码分复用多址***中,可以是码字资源。
可选的, 第一用户设备也可以在未接收第二用户设备的发现消息的 情况下, 直接向第一服务器发送对第二用户设备的直连通信请求。
如图 4所示, 提供了用户设备之间建立直连通信的又一种方式:
401、 第一用户设备接收发自第二用户设备的发现消息 (discovery message ) ;
402、第一用户设备向第一服务器发送对第二用户设备的直连通信请 求;
403、第一服务器向核心网发送第一用户设备对第二用户设备的直连 通信请求;
404、核心网给第一用户设备和第二用户设备分配直连通信资源, 并 向第一服务器下发第一用户设备的直连通信资源, 向服务于第二用户设 备的第二服务器下发第二用户设备的直连通信资源;
405、第一服务器和第二服务器分别给第一用户设备和第二用户设备 下发直连通信资源;
406、 第一用户设备与第二用户设备根据分配的直连通信资源, 建立 直连通信连接, 进行直连通信。
本方案中, 第一服务器服务于第一用户设备, 第二服务器服务于第 二用户设备。 由核心网给第一用户设备和第二用户设备分配直连通信资 源, 并下发给第一服务器和第二服务器, 帮助第一用户设备和第二用户 设备建立直连通信连接。 该第一服务器和第二服务器可以是网络侧的服 务器, 如基站设备 eNodeB、 BTS、 SGW、 PGW、 RNC等, 也可以是用户 侧的簇头 Cluster head或 Wi-Fi热点设备等用户设备管理设备。
可选的, 第一用户设备也可以在未接收第二用户设备的发现消息的 情况下, 直接向第一服务器发送对第二用户设备的直连通信请求。
在用户设备间建立直连通信或进行直连通信的过程中, 由于各个用 户设备的发射功率和相互之间距离不同,可能会出现路损损耗功率过大、 信号接收功率不理想的情况, 影响直连通信的质量。 同时对于一些距离 过远、 发射功率和接收功率无法保证直连通信质量的终端之间, 如果执 行建立直连通信过程或进行直连通信业务, 不但通信质量不佳, 也会干 扰到一定范围内其他的通信业务, 并且带来不必要的信令浪费和用户设 备的电量损耗。
综上, 需要提供一种控制机制, 对于不符合条件的直连通信进行管 控, 优化网络环境。
参考图 5 , 本发明实施例提供了一种通信控制方法, 包括以下步骤:
501、 第一用户设备接收第二用户设备发送的第一消息;
502、 获取第一消息的接收功率;
503、 获取第二用户设备的功率参数信息;
504、根据第二用户设备的功率参数信息和第一消息的接收功率,得 到路径损耗值;
505、根据路径损耗值, 确定是否允许第一用户设备与第二用户设备 进行直连通信。 通过应用本实施例的通信控制方法, 利用消息发送用户设备的功率 参数信息和该消息的接收功率,得到路径损耗值,再根据该路径损耗值, 确定是否允许用户设备之间进行直连通信, 能够实现对用户设备之间直 连通信的管控, 避免用户设备执行功率损耗不理想的直连通信业务和不 必要的信令交互, 降低了用户设备的电量损耗, 同时还避免了通信质量 不佳的直连通信业务对其他通信业务的干扰, 优化了网络环境。
可选的,步骤 502-504可以由第一用户设备执行,也可以由其他设备, 譬如与第一用户设备连接的另一用户设备, 或者连接于第一用户设备的 检测、 计算、 控制装置执行, 也可以由网络服务器、 接入网网元、 核心 网网元或者其他可能的执行主体完成。 本领域普通技术人员可以知道, 只要是能够获取第一用户设备接收第一消息的接收功率, 以及第二用户 设备的功率参数信息, 并能够根据该接收功率和功率参数信息, 通过计 算或者查表等方式得到功率的路径损耗值, 再根据路径损耗值来确定是 否允许第一用户设备与第二用户设备进行直连通信即可执行本发明实施 例, 本发明实施例对于执行以上步骤的执行主体不做限定。
可选的, 该第一消息的接收功率可以通过测量的方式得到, 可以是 第一用户设备进行测量, 也可以是其他装置、 设备进行测量, 本发明对 此不作限定。
可选的, 在确定是否允许第一用户设备与第二用户设备进行直连通 信时, 若该路径损耗值低于第一门限值, 则允许第一用户设备与第二用 户设备进行直连通信; 若该路径损耗值高于该第一门限值, 则不允许第 一用户设备与第二用户设备进行直连通信。 在路径损耗值等于第一门限 值时, 可以允许第一用户设备与第二用户设备进行直连通信, 也可以不 允许第一用户设备与第二用户设备进行直连通信, 从而避免用户设备执 行功率损耗较高的直连通信过程。
可选的, 本发明实施例中的 "允许第一用户设备与第二用户设备进 行直连通信" , 举例来说, 可以是第一设备与第二设备执行建立直连通 信的过程, 如图 1-图 4的直连通信连接建立过程, 即包括第二设备向第 一设备发送发现消息、 第一设备向第二设备发送寻呼消息或者第二设备 向第一设备发送寻呼正确(ACK )消息等过程中的一个或多个步骤; "进 行直连通信" 也可以是第一设备与第二设备在建立直连通信连接后对直 连通信业务的执行, 如执行语音业务、 执行数据业务。 "允许,, 意为第 一用户设备与第二用户设备可以随即进行直连通信, 也可以在之后的某 个时间进行直连通信, 本发明实施例对此不作限制。
可选的, 本发明实施例中的 "不允许第一用户设备与第二用户设备 进行直连通信" , 可以是第一设备和第二设备中断直连通信连接建立过 程, 如第一设备在接收到第二设备发送的发现消息后, 不向第二设备发 送寻呼消息, 或者第一设备在接收到第二设备发送的寻呼消息后, 向第 二设备发送寻呼不正确 (NACK ) 消息; 也可以是第一用户设备与第二用 户设备中止执行直连通信业务或者断开直连通信连接。
可选的, 该第一消息可以是发现消息, 寻呼消息, 寻呼响应消息, 业务消息或是测试消息。 业务消息可以是第二用户设备在与第一用户设 备进行直连通信业务时, 向第一用户设备发送的数据业务消息或者语音 业务消息。 测试消息可以是任意时刻第二用户设备发送的用于测试该消 息的接收功率的消息。
第二用户设备的功率参数信息, 可以是第二用户设备发送第一消息 时的特定的功率参数信息, 也可以是第二用户设备在正常工作时发射信 号、 消息的功率参数信息, 第二用户设备在发送第一消息时的功率, 可 以与第二用户设备正常工作时的发射功率存在差异, 本发明全文对此不 作限制。
可选的, 获取该第二用户设备的功率参数信息包括:
第一消息承载第二用户设备的功率参数信息, 获取第一消息承载的 第二用户设备的功率参数信息; 或者,
接收第二消息, 第二消息承载第二用户设备的功率参数信息, 获取 第二消息承载的第二用户设备的功率参数信息。
具体地, 可以在第二用户设备发送的第一消息中携带其功率参数信 息, 从而可以从第一消息中提取该功率参数信息; 还可以在通过另一消 息, 如第二消息携带第二用户设备的功率参数信息, 该第二消息可以是 由第二用户设备发送的, 可以是由其他用户设备发送的, 还可以是由网 络侧的服务器, 如基站设备 eNodeB、 BTS、 SGW、 PGW、 RNC等, 或是 用户侧的 Cluster head或 Wi-Fi热点设备等用户设备管理设备发送的。譬如 由服务器 eNodeB在其服务范围内广播用户设备发射信号的功率参数信 息, 规定所有或者部分用户设备需要使用该功率参数信息发射信号, 则 该第二消息可以是 eNodeB发送的规定用户设备功率参数信息的广播消 息。
可选的, 第二用户设备的功率参数信息可以是一个特定的第二用户 设备的发射功率值, 还可以是第二用户设备的发射功率范围, 或功率等 级。
若该功率参数信息为发射功率值, 则根据第二用户设备的功率参数 信息和第一消息的接收功率, 得到路径损耗值包括: 根据第二用户设备 的发射功率值和第一消息的接收功率值进行计算, 得到路径损耗值。 譬 如第二用户设备的发射功率值为 23 毫瓦分贝 (dec ibe l s above one mi l l iwa t t in 600 ohms , dBm ) , 接收功率为 5dBm, 则路径损耗值为发 射功率值-接收功率 =18dBm。 需要说明的是, 以上计算路径损耗值的方式 仅仅是一个示例, 也可以根据发射功率值和接收功率, 采用其他方式或 公式计算得到路径损耗值。 此外, 也可以通过查表、 查询数据库等方式, 不通过计算即得到路径损耗值。 譬如, 在数据库中存储了多个发射功率 值、 发射功率值对应的接收功率以及对应的路径损耗值, 则路径损耗值 可以通过查找相应的发射功率值和接收功率得到。
若第二用户设备的功率参数信息为第二用户设备的发射功率范围或 功率等级; 根据第二用户设备的功率参数信息和第一消息的接收功率, 得到路径损耗值包括: 根据第二用户设备的发射功率范围或功率等级, 确定第二用户设备的最大发射功率值; 根据第二用户设备的最大发射功 率值和第一消息的接收功率值进行计算, 得到路径损耗值。 譬如第二用 户设备的发射功率范围为 [ 2 3dBm, 2 OdBm] ,则确定第二用户设备的最大发 射功率为 2 3dBm,接收功率为 5dBm, 则路径损耗值为发射功率值-接收功 率 = 18 dBm。 由于这里的功率范围是一个量化值, 因此可以在消息中, 用 离散的 b i t值表示其功率范围。 比如 00代表 [ 2 3dBm, 2 0dBm] , 01 代表
[ 2 OdBm, 1 7dBm] , 1 0代表 [ 1 7dBm, 1 4dBm]。 又譬如用户设备具有高、 中、 低三种功率等级, 而第二用户设备的功率等级为高功率等级 , 高功率等 级对应的最大发射功率值为 2 3dBm, 接收功率为 5dBm, 则路径损耗值为 发射功率值-接收功率 = 1 8 dBm。对于第二用户设备的功率等级, 也可以根 据其等级确定最大发射功率值或者其他用于计算路径损耗值的功率值。 可以在消息中, 用离散的 b i t值表示其功率等级, 比如 00代表高功率等 级, 01代表低功率等级, 1 0代表中功率等级。 使用最大发射功率值计算 得到的是理论上最大的路径损耗值。也可以采用取功率范围内的中间值、 最小值, 或者任意一个功率值, 与接收功率进行计算得到路径损耗值, 本发明对此不作限定。
需要说明的是, 以上计算路径损耗值的方式仅仅是一个示例, 也可 以根据发射功率范围、 功率等级和接收功率, 采用其他方式或公式计算 得到路径损耗值。 此外, 也可以不通过计算, 通过查表、 查询数据库等 方式, 即得到路径损耗值。 譬如, 在数据库中存储了多个功率等级、 对 应的接收功率以及对应的路径损耗值, 则路径损耗值可以通过查找相应 的功率等级和接收功率得到。 上述的用第一消息或者第二消息的 b i t值指示功率参数信息只是一 种可选的方式。 此外, 还可以通过物理资源的方式指示功率参数信息。 比如, 不同的时间资源指示不同的功率参数信息, 时间资源 1指示
[2 3dBm, 20dBm] , 时间资源 2指示 [20dBm, 1 7dBm] , 时间资源 3指示
20 dBm, 17 dBm]。 例如我们定义在***消息中, 子帧 a和 [ 2 3 dBm, 20 dBm]对 应, 子帧 b和 [20dBm, 17dBm]对应, 子帧 c和 [ 17dBm, 14dBm]对应。 那么当 在子帧 a中发送第一消息时,则表示第一消息的发射功率在 [2 3dBm, 20dBm] 范围内, 或者发射信号的用户设备的最大发送功率值为 23dBm。 另外, 也 可以采用不同的频率资源指示不同的功率参数信息, 不同的码分资源代 表不同的功率参数信息, 或者不同的时间 -频率 -码分资源的组合代表不 同的功率参数信息。 通过传输第一消息的时间资源、 频率资源或者码字 资源指示功率参数信息, 不需要占用消息的字节, 更为筒单、 实用。
可选的, 在步骤 505即确定是否允许第一用户设备与第二用户设备 进行直连通信之前, 还包括: 接收网络服务器发送的第一门限值, 网络 服务器包括 eNodeB, BTS, SGW, PGW , MC或核心网网元; 或者, 接收第 三用户设备发送的第一门限值, 第三用户设备包括 C l us t er head 或 Wi _F i热点设备。 此外, 也可以在第一用户设备上预先存储第一门限值, 通过第一用户设备上预先存储的第一门限值来确定是否与第二用户设备 进行直连通信。 这里的预先存储, 是指第一用户设备在出厂时即写入一 个门限值, 或者是在使用中设置、 更改第一用户设备上的门限值。 本实 施例中, 通过接收网络服务器, 或者其他用户设备发送的第一门限值, 实现对***范围内用户设备之间的直连通信的控制, 满足网络供应商、 电信运营商、 家庭网络拥有者对于直连通信网络的控制需求。
本发明实施例还提供了一种计算机程序产品,包括计算机程序代码, 其中当该计算机程序代码被计算机执行时, 会使得该计算机执行上面实 施例的所有步骤。 图 6a是本发明的又一个实施例, 包括以下步骤:
601、 第一用户设备接收 eNodeB发送的门限值 PL;

605、 第一用户设备根据 P1和 P2, 计算得到路径损耗值 PLa;
606、若 PLa<PL,则第一用户设备向第二用户设备发送寻呼正确( ACK ) 消息。
607、 若 PLa>PL, 则第一用户设备向第二用户设备发送寻呼不正确 ( NACK ) 消息。
本实施例中, eNodeB向第一用户设备发送门限值 PL, 第一用户设备 在与其他用户设备建立直连通信连接的过程中, 基于该门限值 PL, 判断 路径损耗值 PLa是否符合 eNodeB的要求, 符合要求的发送寻呼正确 ( ACK) 消息, 允许其进行直连通信; 不符合要求的发送寻呼不正确 (NACK) 消息, 不允许其进行直连通信, 从而实现了***对于范围内 用户设备建立直连通信的控制, 避免用户设备执行功率损耗不理想的直 连通信业务和不必要的信令交互, 降低了用户设备的电量损耗, 同时还 避免了通信质量不佳的直连通信业务对其他通信业务的干扰, 优化了网 络环境。

6 006、 第一服务器给第一用户设备和第二用户设备分配直连通信资 源。
6 007、 第一用户设备与第二用户设备根据分配的直连通信资源建立 直连通信连接。

举例来说, 实施例中的 "规则,, 规定了可以进行直连通信的功率等 级条件, 具体地, 是关于某个功率等级的用户设备和某个功率等级的用 户设备是否可以进行直连通信的判断标准,可以是表格或者函数关系等。 下表是一个对 "规则,, 的示例, 功率等级分为高等级、 中等级、 低等级 三类:
Figure imgf000027_0001
其中, 第一行表示消息发送设备(第二用户设备) 的功率等级; 第 一列是消息接收设备(第一用户设备) 的功率等级; Y 代表可以进行直 连通信, N 代表不能进行直连通信。 譬如第一用户设备接收到了第二用 户设备的寻呼信号, 并获取第二用户设备的功率等级是 "高等级" , 而 第一用户设备的功率等级是高等级, 经查表得到匹配结果为 Y, 则允许 第一用户设备与第二用户设备进行直连通信。 又比如第一用户设备接收 到了第二用户设备的发现信号, 并获取第二用户设备的功率等级是高等 级, 而第一用户设备的功率等级是中等级, 经查表得到匹配结果为 N, 则不允许第一用户设备与第二用户设备进行直连通信。
在以上实施例中, 若消息接收设备为高功率等级, 而消息接收设备 又接收到了消息发送设备的消息,则无论消息发送设备的功率等级为高、 中或低, 消息发送设备都可以接收到消息接收设备的响应消息, 因此规 则在消息接收设备为高功率等级时, 匹配结果均为 Y; 若消息发送设备 为高功率等级, 二消息接收设备不为高功率等级, 为中功率等级或低功 率等级, 则消息接收设备响应的消息, 消息发送设备不一定能够收到, 匹配结果为 N。 从而避免了进行信号不佳的直连通信。
可选的, 步骤 702-703可以由第一用户设备执行, 也可以由其他设 备, 譬如与第一用户设备连接的另一用户设备, 或者连接于第一用户设 备的匹配、 控制装置执行, 也可以由网络服务器、 接入网网元、 核心网 网元或者其他可能的执行主体完成。 本领域普通技术人员可以知道, 只 要是能够根据第一用户设备的功率等级与第二用户设备的功率等级, 匹 配直连通信的规则, 并根据匹配结果确定是否允许第一设备和第二设备 进行直连通信, 即可执行本发明实施例, 本发明实施例对于执行以上步 骤的执行主体不做限定。

可以用第三消息的 b i t值指示功率等级, 譬如 00表示高等级, 01 表示中等级, 1 0表示低等级。 此外, 还可以通过物理资源的方式指示功 率等级。 比如, 不同的时间资源指示不同的功率等级, 时间资源 1指示 高等级, 时间资源 2指示中等级, 时间资源 3指示 2低等级。 例如我们 定义在***消息中, 子帧 a和高等级对应, 子帧 b和中等级对应, 子帧 c和低等级对应。 那么当在子帧 a 中发送第三消息时, 则表示发送第三 消息的用户设备的功率等级为高等级。 另外, 也可以采用不同的频率资 源指示不同的功率等级, 不同的码分资源代表不同的功率等级, 或者不 同的时间 -频率 -码分资源的组合代表不同的功率等级。 通过传输第一消 息的时间资源、 频率资源或者码字资源指示功率等级, 不需要占用消息 的字节, 更为筒单、 实用。
