通信监听方法、 基站和终端 本申请要求于 2011年 12月 7日提交中国专利局、 申请号为
CN201110403036.0, 发明名称为 "通信监听方法、 基站和终端" 的 中国专利申请的优先权， 其全部内容通过引用结合在本申请中。 技术领域
本发明涉及移动通信技术， 尤其涉及一种通信监听方法、 基站和终端。 背景技术
公安机关或其它部门出于安全的需求， 在法律的授权范围内可以对用 户的通信内容进行监听， 此种监听被称为 "合法监听"。 目前， 由于用户借 助于移动通信网等进行通信时， 诸如用户的语音等数据均由网络进行承载； 例如： 当用户 A与用户 B建立呼叫之后，用户 A的语音发送给用户 A所在 的基站， 然后由用户 A的基站将用户 A的语音发送给 PGW ( Packet Data Network Gateway, 分组数据网关）、 SGW(Seving Gate Way, 服务网关）， 然 后由 PGW可 SGW转发给用户 B所在的基站，由用户 B所在的基站发送给 用户 B, 实现用户 A的语音到用户 B的传递， 用户 B的语音传递给用户 A 时类似； 由于用户的语音等数据由网络承载， 因此现有中需要对用户的语 音等数据进行监听时， 直接从 SGW或 PGW中获取用户的语音等数据， 实 现对用户的监听。然而，随着移动通信技术的发展，基于位置的 D2D(Device to Device, 装置到装置)思想正在被讨论且已有一些应用产生， D2D思想的 核心是假若用户之间的距离足够近时， 用户之间的数据可以直接进行传递， 而不通过网络 载。 发明内容

为了更清楚地说明本发明实施例或现有技术中的技术方案， 下面将对 实施例或现有技术描述中所需要使用的附图作简单地介绍， 显而易见地， 下面描述中的附图仅仅是本发明的一些实施例， 对于本领域普通技术人员 来讲， 在不付出创造性劳动的前提下， 还可以根据这些附图获得其他的附 图。

图 3是关于第一实施例中步骤 S12的流程示意图；
图 4是本发明提供的通信监听方法的第二实施例的流程示意图； 图 5是本发明提供的基站的实施例的结构示意图；
图 6是本发明提供的终端的实施例的结构示意图。 具体实施方式
下面将结合本发明实施例中的附图， 对本发明实施例中的技术方案进 行清楚、 完整地描述， 显然， 所描述的实施例仅仅是本发明一部分实施例， 而不是全部的实施例。 基于本发明中的实施例， 本领域普通技术人员在没 有作出创造性劳动前提下所获得的所有其他实施例， 都属于本发明保护的 范围。
请参考图 1 , 是本发明的通信监听方法的第一实施例的流程示意图， 图 1 的方法流程的执行主体可以是基站， 例如： 可以是在 3GPP ( The 3rd Generation Partnership Project,第三代合作伙伴计划）中称作的 ENB( Evolved Node B, 演进型基站）， 图 1的方法流程包括：
步骤 S11 ,接收第一装置发送的第一消息， 该第一消息用于指示监听属 于 D2D的终端的 D2D数据。
其中， 第一装置可以是 MME ( Mobility Management Entity, 移动性管 理实体）、 PGW、 SGW或第三方客户端； 例如： 当第一装置是 MME, 图 1 的方法流程的执行主体是 ENB时， MME通过与 ENB之间的接口 （该接口 被称为 "S1" 接口）向 ENB发送第一消息， 并在该消息中携带需要监听的 属于 D2D的终端的身份标识， 以指示 ENB需要具体监听的属于 D2D的终 端。 需要说明的是， 第三方客户端是相对于 MME、 SGW和 PGW而言， MME、 SGW和 PGW是核心网中的设备， 第三方客户端是指非核心网中的 设备。 例如： 第三方客户端可以由一台笔记本实现， 将该笔记本与基站相 连接之后， 可以向基站发送第一消息， 以指示基站对属于 D2D 的终端的 D2D数据进行监听。 需要说明的是， D2D数据是指直接由终端到终端， 不 需要网络进行转发的数据。
步骤 S12, 根据所述第一消息， 获取所述 D2D数据。
其中， 获取所述 D2D数据的方式有许多种， 例如： 由属于 D2D的终端 主动上传 D2D数据或者根据所述属于 D2D的终端在进行 D2D通信时所使 用的调度信息， 接收所述属于 D2D的终端的 D2D数据。
步骤 S13 , 将步骤 S12获取的 D2D数据发送至第一装置。
本实施例需要说明的是在 D2D的思想中， 终端在进行 D2D通信时， 实现 D2D通信的信令会全部或部分由网络（包括： 基站、 MME等）承载， 因此网络可以知晓终端何时在进行 D2D通信， 从而在合适的时机对终端的 D2D数据进行监听。
本发明实施例通过向基站发送用于监听属于 D2D的终端的 D2D数据的 第一消息， 基站根据接收的第一消息， 获取属于 D2D的终端的 D2D数据， 从而由基站实现了对 D2D数据的监听，避免现有中由于 D2D数据不通过网 络承载， 而导致的无法对 D2D数据进行监听的缺陷； 本发明实施例非富和 完善了现有的监听方式。
请参考图 2, 是关于第一实施例的步骤 S12的具体描述， 所述步骤 S12 包括：
步骤 S21 , 向所述属于 D2D的终端发送第二消息， 所述第二消息用于 触发所述属于 D2D的终端记录所述 D2D数据。
具体地，在属于 D2D的终端接收到第二消息之后，所述属于 D2D的终 端可以釆用緩存的方式记录 D2D数据。
进一步地，在第二消息中还包括有属于 D2D的终端记录 D2D数据时所 釆用的记录策略； 属于 D2D的终端根据第一消息中包括的记录策略对记录 D2D数据。
在一种实施方式中， 第二消息中的记录策略包括： 属于 D2D的终端需 要记录的 D2D数据的数据量； 例如， 第二消息中的记录策略指示属于 D2D 的终端需要记录 1024字节的 D2D数据。 在另一种实施方式中， 第二消息 中的记录策略包括： 属于 D2D的终端需要对 T时间内的 D2D数据进行记 录， 其中 T为时间段； 例如： 第二消息中的记录策略指示属于 D2D的终端 需要对 12: 00 ~ 12: 10之间总共 10分钟的 D2D数据进行记录。 可以理解 的是， 本领域技术人员可以根据需要， 合理地设置属于 D2D 的终端记录 D2D数据时所釆用的记录策略，例如：在记录策略中指示需要对记录的 D2D 数据保存的时长， 等等； 本实施例不对具体的记录策略进行限定。
步骤 S22 , 接收所述属于 D2D的终端的上报的所述 D2D数据。
具体地，属于 D2D的终端可以在接收到基站的上报 D2D数据的指示时， 被动地向基站上报记录的 D2D数据； 或者， 在完成记录 D2D数据时， 主动 地向基站上报记录的 D2D数据；或者在其它合理的时机由属于 D2D的终端 主动或被动地上^艮记录的 D2D数据， 例如： 基站在空闲时指示属于 D2D 的终端上报记录的 D2D数据。 可以理解的是， 属于 D2D的终端将记录的 D2D数据上报给基站之后， 可以立即将该 D2D数据删除或者保存该 D2D 数据一段时间后， 将其删除。
本实施例由属于 D2D的终端记录 D2D数据，然后发送至基站；对 D2D 数据的监听主要由终端自身实现， 从而对基站的影响较小， 不会加重基站 的负担。
请参考图 3 ,是关于第一实施例的步骤 S12的另一具体描述， 所述步骤 S12包括：
步骤 S31 ,获取所述属于 D2D的终端在进行 D2D通信时所使用的调度 信息。
其中， 基于 D2D的思想， 属于 D2D的终端在建立 D2D通信时， 可以 由属于 D2D的终端确定在 D2D通信时所使用的调度信息，该调度信息包括： 无线资源；也可以由基站为属于 D2D的终端分配在 D2D通信时所使用的调 度信息； 因此步骤 S31在获取属于 D2D的终端在进行 D2D通信时所使用 的调度信息时可能有两种实现方式， 一种是当调度信息由属于 D2D的终端 确定时， 步骤 S31包括： 向属于 D2D的终端发送第三消息， 该第三消息用 于指示所述属于 D2D的终端上报调度信息，并接收所述属于 D2D的终端上 报的调度信息； 另一种是当调度信息由基站为其分配时， 步骤 S31 包括： 通过基站获取属于 D2D的终端在进行 D2D通信时所使用的调度信息，例如: 从基站緩存的调度信息分配记录中获取分配给所述属于 D2D的终端的调度 信息。
步骤 S32, 根据步骤 S31获取的调度信息， 接收 D2D数据。
其中， 步骤 S31获得了属于 D2D的终端在进行 D2D通信时所使用调 度信息时， 步骤 S32根据该调度信息， 接收所述属于 D2D的终端的 D2D 数据， 从而实现了对 D2D数据的监听的目的。 此处需要说明的是， 如果在 调度信息上传输的数据釆用默认的调制方式， 则步骤 S32在根据调度信息 接收到 D2D数据时， 釆用默认的解调方式对接收到的 D2D数据进行解调； 如果在调度信息上传输的数据釆用特别的调制方式， 例如： 由属于 D2D的 终端确定调制方式或者由基站为其分配， 那么步骤 S32还要根据调度信息 获取为接收 D2D数据所需的解调信息，例如： 釆用指示属于 D2D的终端上 传所需的解调信息或从基站的记录中获得所需的解调信息； 在获取所需的 解调信息后， 利用获得的解调信息解调根据调度信息接收到的 D2D数据。
可以理解的是，属于 D2D的终端在进行 D2D通信时，可能出于安全的 需要， 对在调度信息上传输的 D2D数据进行加密处理， 在此种情况上， 步 骤 S32还需要获得相应的加密信息（例如： 密钥信息或加密算法信息）， 从 而利于获得的密钥信息或加密算法信息对根据调度信息接收的 D2D数据进 行解密， 类似地， 如果加密信息由属于 D2D的终端确定， 则指示属于 D2D 的终端上传加密信息； 如果加密信息由基站为其分配， 则通过基站获得加 密信息。
需要说明的是， 在建立 D2D通信时， 属于 D2D的终端在进行 D2D通 信时所使用的调度信息、 解调信息或加密信息可能部分由基站为其分配， 部分由属于 D2D的终端确定，因此上述中的指示属于 D2D的终端上传的调 度信息、 解调信息或加密信息是指由属于 D2D的终端确定的部分。
本实施例基站根据属于 D2D的终端进行 D2D通信时所使用的传输资 源， 接收 D2D数据， 从而实现了对 D2D数据的监听； 由于对 D2D数据的 监听主要由基站实现， 因此可以减少监听对属于 D2D的终端的影响。
请参考图 4, 是本发明的通信监听方法的第二实施例的流程示意图， 图
4与图 1不同的是， 图 4的执行主体可以是属于 D2D的终端， 该属于 D2D 的终端可以是手机和 PDA ( Personal Digital Assistant, 个人数字助理）， 等 等； 具体地图 4的方法流程包括：
步骤 S41 , 属于 D2D的终端接收基站发送的第二消息， 所述第二消息 用于触发所述属于 D2D的终端记录所述终端的 D2D数据。
步骤 S42, 所述属于 D2D的终端根据所述第二消息， 记录所述 D2D数 据。
具体地， 步骤 S42可以釆用緩存的方式记录 D2D数据。
进一步地， 基站发送的第二消息中还包括属于 D2D的终端记录所述终 端的 D2D数据时所釆用的记录策略； 步骤 S42在记录 D2D数据时， 根据 第二消息中的记录策略对 D2D数据进行记录。
在一种实施方式中， 第二消息中的记录策略包括： 属于 D2D的终端需 要记录的 D2D数据的数据量，例如记录策略指示属于 D2D的终端需要记录 1024字节的 D2D数据。在另一种实施方式中，第二消息中的记录策略包括： 属于 D2D的终端需要对 T时间内的 D2D数据进行记录，其中 T为时间段， 例如记录策略指示属于 D2D的终端需要对 12: 10 ~ 12: 15之间总共 5分 钟的 D2D数据进行记录。 可以理解的是， 本领域技术人员可以根据需要， 合理地设置属于 D2D的终端记录所述 D2D数据时所釆用的记录策略，例如 在记录策略中指示需要对记录的 D2D数据保存的时长， 等等。
步骤 S43 , 所述属于 D2D的终端向基站发送所述记录的 D2D数据。 具体地， 步骤 S43可以是接收到基站的上报 D2D数据的指示时， 被动 地向基站上 记录的 D2D数据； 或者， 步骤 S43可以在步骤 S42完成 D2D 数据的记录时， 主动地将步骤 S42记录的 D2D数据发送至基站； 或者步骤 S43在其它合理的时机主动或被动地上报记录的 D2D数据， 例如当接收到 基站在空闲时发送的上报 D2D数据的指示时， 向基站上报步骤 S42记录的 D2D数据。 另外， 需要说明的是属于 D2D的终端将记录的 D2D数据发送 至基站后， 可以立即删除该 D2D数据或者保存预定时长（例如： 一小时、 一天）后删除。
本实施例由属于 D2D的终端记录 D2D数据，然后发送至基站，从而实 现了对 D2D数据的监听； 由于对 D2D数据的监听主要由终端实现， 因此对 基站的影响较小， 不会加重基站的负担。
上述从方法流程对本发明实施例的通信监听方法进行了举例说明， 下 面相应于上述的方法流程， 对本发明实施例的基站和终端， 以及由基站和 终端组成的系统进行举例介绍。
请参考图 5 , 是本发明的基站的实施例的结构示意图， 该基站 5可以是 在 3GPP中称作的 ENB, 具体地基站 5包括：
接收机 51 , 用于接收第一装置发送的第一消息， 该第一消息用于指示 监听属于 D2D的终端的 D2D数据。
其中， 第一装置可以是 MME、 PGW、 SGW或第三方客户端； 例如： 当第一装置是 MME,基站 5为 ENB时 , MME通过与 ENB之间的接口（该 接口被称为 "S1" 接口 )向 ENB发送第一消息， 并在该消息中携带需要监 听的属于 D2D的终端的身份标识， 以指示 ENB需要具体监听的属于 D2D 的终端。 此处需要说明的是， 第三方客户端是相对于 MME、 SGW和 PGW 而言， MME、 SGW和 PGW是核心网中的设备， 第三方客户端是指非核 心网中的设备。 例如： 第三方客户端可以由一台笔记本实现， 将该笔记本 与基站相连接之后， 可以向基站发送第一消息， 以指示基站对属于 D2D的 终端的 D2D数据进行监听。 需要说明的是， D2D数据是指直接由终端到终 端， 不需要网络进行转发的数据。
处理器 52, 用于根据第一消息， 获取 D2D数据。
其中，监听模块 52获取 D2D数据的方式有许多种，例如： 由属于 D2D 的终端主动上传 D2D数据或者根据所述属于 D2D的终端在进行 D2D通信 时所使用的调度信息， 接收所述属于 D2D的终端的 D2D数据。
发送机 53 , 用于将处理器 52获取的 D2D数据发送至第一装置。
本实施例需要说明的是在 D2D的思想中， 终端在进行 D2D通信时， 实现 D2D通信的信令会全部或部分由网络（包括： 基站、 MME, 等）承载， 因此网络可以知晓终端何时在进行 D2D通信， 从而可以在合适的时机监听 进行 D2D通信所产生的 D2D数据。
本发明实施例通过向基站发送用于监听属于 D2D的终端的 D2D数据的 第一消息， 基站根据接收的第一消息， 获取属于 D2D的终端的 D2D数据， 从而由基站实现了对 D2D数据的监听，避免现有中由于 D2D数据不通过网 络承载， 而导致的无法对 D2D数据进行监听的缺陷。
下面对图 5所示的基站实现 D2D数据的监听进行更具体的补充说明。 在一种实施方式中， 发送机 51 , 还用于向属于 D2D的终端发送第二消 息 ,所述第二消息用于触发所述属于 D2D的终端记录所述终端的 D2D数据。
具体地，第二消息中还包括有属于 D2D的终端记录 D2D数据时所釆用 的记录策略； 属于 D2D的终端根据第二消息中的记录策略记录 D2D数据， 实现对 D2D数据的监听。 例如： 记录策略可以包括： 需要记录的 D2D数据 的数据量， 该数据量的大小可以根据需要进行灵活设定， 本实施例不作限 定； 记录策略还可以包括： 需要对 T ( T为时间段） 时间内的 D2D数据进 行记录， 可以将 T设置为 12: 00 - 12: 05或者 13: 00 ~ 14: 00或其它， 本实施例不作具体的限定； 记录策略还可以根据实际需要被合理地设置， 例如在记录策略指示需要对记录的 D2D数据保存的时长， 本实施例不对记 录策略的具体内容进行限定。
接收机 53 , 还用于接收属于 D2D的终端上报的 D2D数据。
具体地，属于 D2D的终端可以在接收到基站的上报 D2D数据的指示时， 被动地向基站上报 D2D数据； 或者， 在完成 D2D数据的记录时， 主动地向 基站上报记录的 D2D数据； 或者， 在其它合理的时机主动或被动地向基站 上报记录的 D2D数据， 例如： 接收到基站空闲时发送的上报指示时， 被动 地向基站上报 D2D数据。 可以理解的是， 属于 D2D的终端上报 D2D数据 之后，可以即刻删除已上报的 D2D数据或者将 D2D数据再保存预定时长（例 如： 一小时、 一天）后删除。
本实施方式中由属于 D2D的终端记录 D2D数据， 然后将 D2D数据上 报给基站， 从而实实现了对 D2D数据的监听； 由于在本实施方式中对 D2D 数据的监听由属于 D2D的终端记录， 因此对基站可以花费较小的资源在实 现对 D2D数据的监听上， 从而降低了基站的负担。 在另一种实施方式中， 处理器 52, 还用于获取属于 D2D的终端在进行 D2D通信时所使用的调度信息； 及根据所述调度信息， 接收 D2D数据。
具体地， 在 D2D通信中， 调度信息可以由属于 D2D的终端确定， 也可 以由基站为属于 D2D的终端分配。因此当调度信息由属于 D2D的终端确定 时， 所述处理器 52向所述属于 D2D的终端发送第三消息， 所述第三消息 用于指示所述属于 D2D的终端上报调度信息，并由接收机 51接收属于 D2D 的终端上报的调度信息， 处理器 52从接收机 51 中获取调度信息。 当调度 信息由基站为属于 D2D的终端分配时， 则处理器 52通过基站获取调度信 息。
当处理器 52获取的调度信息时， 根据调度信息， 接收属于 D2D的终 端的 D2D数据， 实现对 D2D数据的监听。 可以理解的是， 如果在调度信息 上传输的数据釆用默认的调制方式，则处理器 52根据调度信息接收到 D2D 数据时， 釆用默认的解调信息解调 D2D数据； 如果在调度信息上传输的数 据釆用特殊的调制方式， 特殊的调制方式包括： 由属于 D2D的终端确定的 调制方式或由基站为属于 D2D的终端在进行 D2D通信时所分配的调制方 式， 则处理器 52根据调度信息接收到 D2D数据时， 釆用与特殊的调制方 式相应的解调信息解调 D2D数据 ,此处当特殊的调制方式由属于 D2D的终 端确定时， 则指示属于 D2D的终端上^艮相应的解调信息， 当特殊的调制方 式由基站为属于 D2D的终端分配时， 则通过基站获取相应的解调信息。 可 以理解的是， 属于 D2D的终端在进行 D2D通信时， 出于安全的需要， 可以 将在调度信息上传输的 D2D数据加密， 因此在此种情况下， 处理器 52还 要获得加密 D2D数据时所使用的加密信息 （包括但不限于： 密钥）， 并利 于获得的加密信息解密 D2D数据； 类似地，如果加密信息由属于 D2D的终 端确定， 则指示属于 D2D的终端上传加密信息； 如果加密信息是由基站为 属于 D2D 的终端分配， 则通过基站获取加密信息； 需要说明的是， 属于 D2D的终端进行 D2D通信时所使用的调度信息、解调信息或加密信息可能 全部或部分由基站分配， 全部或部分由属于 D2D的终端确定， 因此上述中 的指示属于 D2D的终端上传的调度信息、 解调信息或加密信息是指由属于 D2D的终端确定的那部分。 本实施例通过获取属于 D2D的终端进行 D2D通信时所使用的传输资 源， 并根据传输资源， 接收 D2D数据， 实现了对 D2D数据的监听； 由于对 D2D数据的监听主要是由基站根据传输资源接收 D2D数据， 不需要属于 D2D终端花费任何资源在 D2D数据的监听上， 因此对属于 D2D的终端影 响面小。
请参考图 6, 是本发明的终端的实施例的结构示意图， 该终端 6可以是 手机或 PDA等； 具体地， 终端 6包括：
接收机 61 , 用于接收基站发送的第二消息， 所述第二消息用于触发所 述终端 6记录 D2D数据。
处理器 62, 用于才艮据第二消息， 记录（例如： 通过緩存的方式）终端
6的 D2D数据。
进一步地， 第二消息中包括有终端 6记录 D2D数据时所釆用的记录策 略； 当接收机 61接收到第二消息时， 处理器 62根据第二消息中的记录策 略， 记录 D2D数据。 具体地， 记录策略可以包括： 终端 6需要记录的 D2D 数据的数据量， 例如记录策略指示终端 6需要记录 1024字节的 D2D数据。 记录策略还可以包括： 终端 6需要对 T ( T为时间段） 时间内的 D2D数据 进行记录， 例如记录策略指示终端 6需要记录 12: 00 ~ 12: 10之间总共 10 分钟的 D2D数据。 可以理解的是， 本领域技术人员可以根据需要， 合理地 设置终端 6记录 D2D数据时所釆用的记录策略， 例如在记录策略中指示需 要对记录的 D2D数据保存的时长， 等等。
发送机 63 , 用于将处理器 62记录的 D2D数据发送至基站。
具体地， 发送机 63在接收机 61接收到基站的上报 D2D数据的指示， 将处理器 62记录的 D2D数据发送至基站； 或者， 发送机 63在处理器 62 完成 D2D数据的记录时， 将处理器 62记录的 D2D数据发送至基站； 或者 发送机 63也可以在其它合理的时机将处理器 62记录的 D2D数据发送至基 站， 例如在接收机 61接收到基站空闲时发送的 D2D数据上报指示时。 可 以理解的是， 发送机 62将 D2D数据上报给基站后， 处理器 62立即删除已 上报的 D2D数据或者将 D2D数据保存预定时长 (例如一天）后删除。
本实施例由终端 6记录 D2D数据， 并发送至基站， 从而实现了对 D2D 数据的监听， 并且此种监听主要由终端 6 实现， 因此对基站的影响小， 不 会加重基站的负担。
