Description

一种集群用户识别方法及装置
技术领域
本发明涉及通信领域, 尤其是涉及一种集群用户识别方法及装置。 背景技术
随着长期演进( Long Term Evolution, LTE )技术的发展, 在公共 LTE 网络上实现丰富的集群业务成为可能。 所谓集群业务主要是指一类特殊的 通信系统, 提供单向的通话能力, 允许用户 ( User Equipment, UE ) 同一 个或多个其他 UE进行语音等方式的通信。 如果 LTE网络中的 UE长时间 没有业务, 则该 UE会进入空闲状态 ( EMM_IDLE状态), 此时如果该 UE 所注册网络有数据要发送给该 UE或该 UE本身要向所在网络发起业务请求 时, 演进基站 ( evolved Node B , eNB )要为该 UE分配的承载资源, 使所 述空闲状态的 UE 重新与所述 eNB 建立 RRC 连接从而转换成连接状态 ( EMM_CONNECTED状态), 这样才能接收所注册网络发送的数据, 或者 本身向所在网络发起业务请求。
现有技术中, 当空闲状态的 UE 需要在所属群组中发起集群业务或者 该 UE所在群组中有集群业务要发送给该 UE时,集群通信业务使能服务器 ( Group Communication Service Enabler Server, GCSE Server )会发送携带 所述空闲状态的 UE 所属群组的临时移动群组标识 (Temporary Mobile Group Identity , TMGI ) 的集群业务建立请求, 广播-多播业务中心 ( Broadcast-Multicast Service Centre, BM-SC )接收到所述集群业务建立请求 后, 发送携带所述 TMGI的会话开始请求, 所述 eNB在接收到所述会话开 始请求后发出携带所述 TMGI的广播消息, 所述空闲状态的 UE监听所述 eNB的广播消息, 如果发现携带的所述 TMGI与自身所属群组的 TMGI相 同, 则所述 UE选择向所述 eNB返回群组通知消息, 所述群组通知消息包 含所述 TMGI, 所述 eNB判断接收到的所述群组通知消息中包含的 TMGI 是否与所述集群业务建立请求中的 TMGI相同, 如果相同, 则判定返回所 述群组通知消息的 UE与本次集群业务相关,向所述 UE分配对应的承载资 源, 以使得所述处于空闲状态的 UE重新与所述 eNB建立连接, 转换成连 接状态, 并为其建立集群业务传输承载。
但是现有技术的集群用户识别的问题是, 由于 eNB发出的广播消息中 本身就已经包含了 TMGI, 而且信号范围内的所有 UE都可以接收, 也就是 说, 有些并不属于所述 TMGI对应的群组的 UE也可以接收这则广播消息 并以此获得其中的所述 TMGI,如果 UE也向 eNB返回一个包含所述 TMGI 的群组通知消息, eNB收到 UE的群组通知消息后同样也会为这个与本次 集群业务不相关的 UE分配对应的承载资源, 这就造成了资源浪费。 发明内容

所述 UE在向集群通信业务使能服务器 GCSE Server进行集群业务注册 时, 所述 UE获取所述 GCSE Server发送的第二临时群组标识 TMGI和第二群 组签名, 所述第二 TMGI和第二群组签名对应所述 UE注册集群业务的群组。

所述 UE向所述识别设备返回所述群组通知消息, 以使得所述识别设备确 定确认所述第二 TMGI和第二群组签名以及所述第一 TMGI和第一群组签名是 否分别一致; 如果分别一致, 所述识别设备识别所述 UE属于所述会话开始请 求中所述第一 TMGI以及第一群组签名所对应的群组。
第六方面, 本发明提供了一种集群用户识别装置, 包括:
第一获取单元, 用于获取识别设备发送的群组标识消息, 所述群组标识消 息中包括所述第一 TMGI;

现有技术中, 由于 eNB发出的广播消息中本身就包含了 TMGI, 不属 于所述 TMGI对应的群组的 UE也可以向所述 eNB返回携带有所述 TMGI 的群组通知消息, 由于所述 eNB仅返回的群组通知消息中是否携带有相同 的 TMGI作为识别的条件, 故这种情况下, 所述 eNB无法正确识别出 UE 的真实的群组成员身份, 同样也会为这个与本次集群业务不相关的非法的 UE分配承载资源, 由此造成了资源浪费。 针对这一技术问题, 本发明技术 方案提供了一种有效的识别群组成员 UE的实施例。在 UE注册群组时, 集 群服务器 GCSE Server将 UE 所注册的群组的 TMGI 和对应的群组签名 ( group signature )发送给 UE。 当有集群业务发起时 (或者说有处于空闲 状态的 UE需要在所在的一群组中发起集群业务或者该 UE所在群组中有集 群业务要发送给该 UE时), GCSE Server发送到识别设备的会话发起请求 中既包含该群组的 TMGI, 也包含了该群组对应的群组签名, 识别设备发 送包含有 TMGI的广播消息, 当 UE接收所述广播消息后, 返回群组通知 消息,所述群组通知消息中必须包含 TMGI和对应的群组签名, 由于群组签 名并不包含在所述广播消息中,即使有与本次集群业务不相关的非法的 UE 接收了所述广播消息并通过一定手段获取了其中的所述 TMGI, 也无法直 接获取与所述 TMGI对应的群组签名, 这样识别设备可以通过比对群组通 知消息中的群组签名和会话开始请求中的群组签名是否相同来有效的识别 出与本次集群业务相关的群组成员 UE。 由此能够有效排除掉非法的 UE, 大大节约系统资源。
针对现有技术的这一技术问题, 本发明技术方案还提供了另一种有效 的识别群组成员 UE 的实施例。 由于每个移动性管理网元 ( Mobility Management Entity, MME )均管理多个 UE, 该实施例在 UE注册群组时所获 取的 TMGI也会被管理该 UE的 MME获取,也就是说 MME能够明确所管 理的各个 UE所属群组的 TMGI。 那么在集群业务组呼承载建立过程中, 当 所述 MME接收到具有 TMGI的会话开始请求时,可以从所管理 UE中确定 出具有与所述会话开始请求中 TMGI相同的 UE, 并向确定出的所述 UE发 起寻呼, 所述寻呼只有确定出来的 UE 才能接收到, 杜绝了其他与本次会 话开始请求所对应群组不相关的 UE 收到寻呼消息的可能性, 更不会出现 eNB为这些非法的 UE分配承载资源的情况, 由此大大节约了系统资源。
为了使本技术领域的人员更好地理解本发明实施例的方案, 下面结合 附图和实施方式对本发明实施例作进一步的详细说明。
实施例一
本实施例详细说明使用群组签名的方式识别集群用户的方法, 请参阅 图 1, 其为本发明实施例提供的一种集群用户识别的方法流程图, 所述方法 包括以下步骤:
预置步骤 S100: UE具有所注册群组对应的 TMGI以及对应的群组签名。 本步骤为预先设置的, 仅在 UE注册群组时才需要被执行。 在 UE群组业 务注册时, 除了会获取所注册群组的 TMGI, 还同时获取所注册群组对应的群 组签名 group signature, 这样在后续进行用户识别的时候, 可以根据群组签名 进行有效地判断。
UE是如何具有所注册群组对应的 TMGI和对应的群组签名, 需要在 UE 在 GCSE Server进行集群业务注册进行改进, 具体为, 所述 UE所具有的所述 所述 GCSE Server根据所述集群业务注册的群组向所述 UE发送的,也就是说, 在现有技术的基础上, 要所述 GCSE Server除了要向进行集群业务注册的 UE 返回对应的 TMGI以外, 还要返回对应的群组签名。
S101 : 识别设备接收来自 BM-SC的会话开始请求, 所述会话开始请求包 括第一 TMGI以及第一群组签名。
需要说明的是,识别设备接收会话开始请求的条件是在有集群业务发起的 情况下, 当有集群业务发起时(或者说有处于空闲状态的 UE需要在所在的 一群组中发起集群业务或者该 UE 所在群组中有集群业务要发送给该 UE 时), GCSE Server会向 BM-SC发送包含对应所述集群业务的第一 TMGI和第 一群组签名的集群业务建立请求; 所述 BM-SC接收到所述集群业务建立请求 后, 发送所述会话开始请求。 所述会话开始请求会多次转发后到达识别设备, 虽然所述会话开始请求中包含有群组签名, 但是其中的转发过程属于现有技 术,这里就不再赘述。所述第一 TMGI和第一群组签名是当前发起的集群业务 所对应群组的 TMGI和群组签名。
S102: 所述识别设备发送群组标识消息, 所述群组标识消息中包括所述第 ― TMGL
S103: 所述识别设备接收 UE返回的群组通知消息, 所述群组通知消息包 括第二 TMGI和第二群组签名。
这里需要说明的是,所述群组通知消息的涵盖范围是识别设备的信号覆盖 范围内,所有处于所述识别设备信号覆盖范围内的 UE均可以监听到所述广播 消息。所述群组通知信息携带的第一 TMGI的作用和现有技术相同,是为了让 空闲状态的 UE可以在监听到所述群组通知信息后,通过比对自身所属群组的 TMGI(s)中是否有与所述群组通知消息中 TMGI相同, 来确定是否返回群组通 知消息。 同样, 所述群组通知信息也会有可能被并不具有第一 TMGI的 UE选 择接收。 但是, 本发明技术方案的改进点在于, 所述识别设备并不会将所述会 话开始请求中的第一群组签名添加到所述广播消息中, 而且, UE在确认接收 所述广播消息后, 除了需要在返回的群组通知消息中携带 TMGI以夕卜,还需要 携带与返回的 TMGI对应的群组签名,用于识别设备验证所述 UE是否是所述 广播消息中的第一 TMGI所对应的群组的一员, 也就是身份合法性的验证。
S104: 所述识别设备确认所述第二 TMGI 和第二群组签名以及所述第一 TMGI和第一群组签名是否分别一致。
S105: 如果分别一致, 所述识别设备识别所述 UE属于所述会话开始请求 中所述第一 TMGI以及第一群组签名所对应的群组。
也就是说, 在 S104中, 识别设备除了对 TMGI进行比对以外, 还进一步 的对群组签名进行比对,来验证返回群组通知消息的 UE的身份,在步骤 S103 中, 即使有 UE通过接收群组标识消息的方式获取了其中的第一 TMGI, 并将 第一 TMGI附加在返回识别设备的群组通知消息中,该 UE也无法得知对应第 一 TMGI的群组签名, 即使返回了 TMGI和群组签名,其返回的群组签名肯定 也是错误的,那么这种情况下识别设备在比对第一群组签名和第二群组签名的 结果必然是两者不一致。只有识别设备确定出第一 TMGI和第二 TMGI—致以 及第一群组签名和第二群组签名也一致的情况下, 才会识别返回第二 TMGI 和第二群组签名的 UE为属于所述会话开始请求中所述第一 TMGI以及第一群 组签名所对应的群组的 UE。
当识别设备识别出 UE是所述会话开始请求中所述第一 TMGI以及第一群 组签名所对应群组的群组成员后,将为所述 UE分配承载资源,使得所述处于 空闲状态的 UE重新与所述 eNB建立连接, 转换成连接状态。
完成上述步骤后, eNB会向 MME发送会话开始响应消息( Session start Response )。 MME收到所述会话开始响应消息后,通过 MBMS网关(MBMS Gateway, MBMS-GW ) 转发给 BM-SC。 BM-SC向 GCSE Server发送集群 业务建立响应消息( Group Communication Setup Response ), 完成集群组呼 业务承载的建立。 集群组呼业务承载建立完成后, GCSE Server通过组呼业 务承载向群组成员 (其中就包括刚转换成连接状态的所述 UE )发送集群组 呼业务消息, 进行集群业务通信。
在本发明中, 所述识别设备可以包括多种不同的实体设备, 并随着识别任 务的分配不同有着多种不同的实施方式,接下来将以信令交互的方式,详细介 绍本发明技术方案中较为优选的两种实施例。
如图 2所示, 其为本发明实施例提供的一种集群用户识别方法的信令图, 所述识别设备包括演进基站 eNB, 在本实施例中, 所述 eNB将作为识别 UE 的设备。
S200: UE具有所注册群组对应的 TMGI和群组签名。
需要说明的是, 所述 UE所具有的所述 TMGI以及群组签名是当所述 UE 在所述 GCSE Server进行集群业务注册时,所述 GCSE Server根据所述集群业 务注册的群组向所述 UE发送的。
S201 : 所述 eNB接收所述 MME转发的来自 BM-SC的会话开始请求, 所 述会话开始请求包括第一 TMGI以及第一群组签名。
S202: 所述 eNB向 UE发送所述广播消息, 所述广播消息中包括所述第 ― TMGL
S203: 确认接收所述广播消息的 UE向所述识别设备返回群组通知消息, 所述群组通知消息包括第二 TMGI和第二群组签名。
S204:所述 eNB确认所述第二 TMGI和第二群组签名以及所述第一 TMGI 和第一群组签名是否分别一致。
如果一致, 所述 eNB 识别所述 UE属于所述会话开始请求中所述第一 TMGI以及第一群组签名所对应的群组。
对于如图 2所示实施例需要说明的是,所述 eNB在步骤 S201中就已经获 取了对应本次会话开始请求所对应群组的第一 TMGI和第一群组签名,故在步 骤 S204接收到 UE返回的群组通知消息后便可以直接进行比对验证所述群组 通知消息中的第二 TMGI和第二群组签名与之前获取的第一 TMGI和第一群组 签名之间是否分别一致。 并且所述 eNB会在识别后向识别出的 UE分配对应 的承载资源, 建立与所述识别出的 UE的连接。
如图 3所示, 其为本发明实施例提供的一种集群用户识别方法的信令图, 所述识别设备包括移动性管理网元 MME, 在本实施例中, 所述 MME将作为 识别 UE的设备。
S300: 用户设备 UE具有所注册群组对应的 TMGI和群组签名。
需要说明的是, 所述 UE所具有的所述 TMGI以及群组签名是当所述 UE 在所述 GCSE Server进行集群业务注册时,所述 GCSE Server根据所述集群业 务注册的群组向所述 UE发送的。
S301a: 所述 MME接收来自 BM-SC的会话开始请求, 所述会话开始请求 包括对应同一群组的第一 TMGI以及第一群组签名。
S301b: 所述 MME将不包含所述第一群组签名的会话开始请求发送到所 述 cNB。
S302: 所述 eNB根据接收到所述不包含所述第一群组签名的会话开始请 求后发送广播消息, 所述广播消息中包括所述第一 TMGI。 S303: 所述 MME接收所述 eNB转发来自 UE的所述群组通知消息。
S304: 所述 MME 确认所述第二 TMGI 和第二群组签名以及所述第一 TMGI和第一群组签名是否分别一致;
如果一致, 所述 MME识别所述 UE属于所述会话开始请求中所述第一 TMGI以及第一群组签名所对应的群组。
如图 3所示实施例需要说明的是,由于在步骤 S301b中所述 MME并没有 将第一群组签名发送给 eNB, 所以对于所述 eNB来说, 是无法验证 UE返回 的群组通知消息中的第二群组签名是否合法的,故在步骤 S303中所述 eNB需 要将接收的群组通知消息转发给所述 MME, 由所述 MME来完成对 UE的验 证。当所述 MME通过比对验证所述群组通知消息中的第二 TMGI和第二群组 签名与之前获取的会话开始请求中的第一 TMGI 和第一群组签名是否分别一 致后, 由于分配承载资源的功能需要所述 eNB来完成, 故所述 MME将会将 识别出的 UE的相关信息发送给所述 eNB,所述 eNB根据所述 UE的相关信息 以及之前获取的所述第一 TMGI, 识别出 UE以及所属的群组, 并为所述 UE 分配对应的承载资源, 建立与其的连接。
通过本实施例可以看出, 在 UE进行注册群组时除了获取 TMGI, 还额 外获取对应的群组签名, 并向识别设备返回包含 TMGI和群组签名的群组 通知消息, 由于群组签名并不没有包含在识别设备发送的广播消息中, 所 以即使有 UE接收所述广播信息, 并获取了消息中的 TMGI, 也无法获取对 应的群组签名, 这样识别设备可以通过比对群组通知消息中的群组签名和 会话开始请求中的群组签名是否相同来有效的识别返回群组通知消息的 UE是否为与所述会话开始请求相关的 UE, 这样就能够有效排除与所述会 话开始请求不相关的非法 UE, 大大节约系统资源。 实施例二
本实施例将对使用 MME确定出所管理 UE 中与本次集群业务相关的 UE后, 向确定出的 UE发送指定寻呼的集群用户识别方法进行描述。 请参 阅图 4, 其为本发明实施例提供的一种集群用户识别的方法流程图, 所述 方法包括以下步骤: 设置步骤 S400: 当 MME所管理的用户设备 UE在 GCSE Server进行集群 业务注册后, 所述 MME从所述 GCSE Server得到所述 UE进行所述集群业务 注册时获取的临时群组标识 TMGI。
这里需要说明的是, 本步骤是属于预先设置的步骤, 在设置好后, 只要所 管理的 UE没有注册新的群组, 本步骤是不需要再被执行的。 只要当 MME所 管理的 UE在集群业务使能服务器 GCSE Server进行集群业务注册后, 所述 MME从所述 GCSE Server得到所述 UE 进行所述集群业务注册时获取的 TMGI。 所述 MME获取所管理的各个 UE所在群组的 TMGI的方式本发明并 不进行限定, 但是提供了一种优选的获取方式, 在 UE注册群组后, 为其建 立集群业务单呼承载过程中, 将所述 UE所属群组的 TMGI发送给管理该 UE的 MME。 请参阅图 5, 其为本发明实施例提供的 MME获取所管理 UE所 在群组的 TMGI的信令图,包括 GCSE Server,策略与计费功能实体( Policy and Charging Rules Function, PCRF )、 PDN网关( PDN Gateway, PGW )和 MME:
S500: UE在 GCSE Server进行集群业务注册, 获取从所述 GCSE Server 根据所述集群业务注册的群组向所述 UE发送的 TMGI。
S501:所述 GCSE Server向所述 PCRF发送 Rx接口会话建立请求信息( Rx Session Setup Request ),所述 Rx接口会话建立请求信息包括所述 UE进行集群 业务注册获取的所述 TMGI, 所述 Rx接口会话建立请求信息用于建立集群单 呼业务承载。
S502:所述 PCRF向所述 PGW发送 Gx接口会话修改请求消息( Gx Session
Modification Request ), 所述 Gx接口会话修改请求消息包括所述 UE进行集群 业务注册获取的所述 TMGI。
S503: 所述 PGW发送承载资源分配消息 ( Bearer Resource Allocation ), 所述承载资源分配消息包括所述 UE进行集群业务注册获取的所述 TMGI。
S504: 所述 MME获取所述承载资源分配消息并保存所述 UE进行集群业 务注册获取的所述 TMGI。
通过上述方式, MME将在所管理的 UE在 GCSE Server进行集群业务注 册后, 获取对应的 TMGI。 S401 : 所述 MME接收来自 BM-SC的会话开始请求, 所述会话开始请求 包括第三 TMGI。
需要说明的是,所述 MME接收会话开始请求的条件是在有集群业务发起 的情况下, 当有集群业务发起时(或者说有处于空闲状态的 UE需要在所在 的一群组中发起集群业务或者该 UE所在群组中有集群业务要发送给该 UE 时), GCSE Server会向 BM-SC发送包含对应所述集群业务的第三 TMGI的集 群业务建立请求; 所述 BM-SC接收到所述集群业务建立请求后, 发送所述会 话开始请求。 所述会话开始请求会多次转发后到达所述 MME。
S402: 所述 MME根据所述第三 TMGI从所述所管理的 UE中识别出属于 所述第三 TMGI对应群组的目标 UE。
也就是说, 由于之前在步骤 S400中所述 MME已经获得了所管理的各个 UE所在群组的 TMGI, 当所述 MME获取所述第三 TMGI后, 便可以从所管 理的 UE中确定出具有第三 TMGI的空闲状态的目标 UE, 比如说, MME管理 了 10个 UE, 且所述 MME已经明确了这 10个 UE各自所属的一个或多个群 组的 TMGI信息, 当所述 MME接收到一个会话开始请求, 从所述会话开始请 求中获取了第三 TMGI, 所述 MME根据所述第三 TMGI从所管理的 UE各自 的 TMGI中进行比对,比如说其中有 5个处于空闲状态的 UE都具有第三 TMGI (也就是说这 5个处于空闲状态的 UE都是第三 TMGI所对应群组的群组成 员), 那么所述 MME就确定出这 5个 UE为目标 UE。
可选的,在确定出目标 UE后,便可以通过 eNB向所述目标 UE发起指定 的寻呼消息, 所述寻呼消息只有确定出来的所述目标 UE才能够接收的到。
也就是说,所述 MME通过 eNB向所述目标 UE发起寻呼消息,所述寻呼 消息中包括所述第三 TMGI, 以使得所述目标 UE在接收所述寻呼消息后发起 业务请求消息, 使得所述 eNB识别所述目标 UE属于所述第三 TMGI所对应 的群组。
需要注意的是, 由于确定出的目标 UE最终需要由所述 eNB识别并分 配对应的承载资源, 故接下来将依据信令图的方式, 对所述 eNB识别目标 UE的方式进行介绍。
故在所述 MME通过所述 eNB发起寻呼消息的情况下,请参阅图 6, 其为 本发明实施例提供的一种集群用户识别方法的信令图, 包括:
S600: 所述 MME具有所管理的 UE所在群组的 TMGI。
S601 : 所述 MME接收来自 BM-SC的会话开始请求, 所述会话开始请求 包括第三 TMGI。
S602: 所述 MME根据所述第三 TMGI从所述所管理的各个 UE中确定出 属于所述第三 TMGI对应群组的空闲状态的目标 UE。
S603: 所述 MME通过 eNB向所述目标 UE发起寻呼消息,所述寻呼消息 中包括所述第三 TMGI。
所述 eNB, 以使得所述 eNB识别所述目标 UE属于所述第三 TMGI所对应的 群组。
需要说明的是, 所述 eNB在步骤 S603和 S604中虽然传递了消息, 但是 并没有获取能够直接向目标 UE分配承载资源的必要信息, 所以在 S604中当 所述 MME接收到的上述目标 UE返回的业务请求消息后, 会将返回所述业务 请求消息的目标 UE的初始上下文(Initial UE Context ) 以及对应本次会开开 始请求的群组的第三 TMGI发送给所述 eNB, 以使得所述 eNB能够通过这些 信息识别出目标 UE以及所述目标 UE所在的群组, 并以此为所述目标 UE分 配对应所述第三 TMGI的群组的承载资源。
从本实施例中可以看出, MME预先明确所管理的注册为群组成员各个 UE所属群组的 TMGI, 这样当所述 MME接收到会话开始请求时, 根据所 述会话开始请求中的 TMGI确定出所管理的 UE中具有相同 TMGI的 UE, 并仅向确定出来的 UE发送寻呼消息,这样只有通过 MME确认过的 UE才 能收到寻呼消息,杜绝了其他与本次会话开始请求所对应群组不相关的 UE 收到寻呼消息的可能性, 由此 eNB只会为这些由所述 MME确认出的 UE 分配承载资源, 由此大大节约了系统资源。 实施例三
图 7为本发明实施例提供的一种集群用户识别的方法流程图,如图 7所示, 包括:
S701 : 用户设备 UE获取识别设备发送的群组标识消息, 所述群组标识消 息中包括所述第一 TMGI。
这里所述的 UE主要是指处于空闲状态的 UE, 所述 UE具有所在群组的 第二 TMGI和第二群组签名,所述第二 TMGI和第二群组签名是所述 UE在进 行集群业务注册时获得的, 也就是说, 可选的, 在所述 UE获取识别设备发送 的群组标识消息之前, 还包括:
所述 UE在向 GCSE Server进行集群业务注册时,所述 UE获取所述 GCSE Server发送的第二 TMGI和第二群组签名,所述第二 TMGI和第二群组签名对 应所述 UE注册集群业务的群组。
S702: 当所述第一 TMGI和所述 UE自身的第二 TMGI相同时, 所述 UE 向所述识别设备返回群组通知消息, 所述群组通知消息包括所述 UE自身的所 述第二 TMGI和第二群组签名。
也就是说, 相比现有技术, 除了返回自身的所述第二 TMGI以外, 还会额 外返回所述第二群组签名以便所述识别设备进一步通过所述第二群组签名验 证所述 UE是否是所述广播消息中的第一 TMGI所对应的群组的一员,也就是 身份合法性的验证。可选的,所述 UE向所述识别设备返回所述群组通知消息, 以使得所述识别设备确定确认所述第二 TMGI 和第二群组签名以及所述第一 TMGI和第一群组签名是否分别一致; 如果分别一致, 所述识别设备识别所述 UE属于所述会话开始请求中所述第一 TMGI 以及第一群组签名所对应的群 组。
可见, UE在获取识别设备发送的群组标识消息时, 将会选择返回自身的 第二 TMGI和第二群组签名,以便所述识别设备进一步通过所述第二群组签名 验证所述 UE是否是所述广播消息中的第一 TMGI所对应的群组的一员,这样 就能够有效排除与所述会话开始请求不相关的非法 UE, 大大节约系统资 源。
实施例四
图 8为本发明实施例提供的一种集群用户识别的装置结构图,如图 8所示, UE具有所注册群组对应的 TMGI和群组签名, 所述集群用户识别装置 800包 括:
接收单元 801,用于接收来自广播-多播业务中心 BM-SC的会话开始请求, 所述会话开始请求包括第一 TMGI以及第一群组签名。
需要说明的是,所述接收单元 801接收会话开始请求的条件是在有集群业 务发起的情况下, 当有集群业务发起时(或者说有处于空闲状态的 UE需要 在所在的一群组中发起集群业务或者该 UE 所在群组中有集群业务要发送 给该 UE时), GCSE Server会向 BM-SC发送包含对应所述集群业务的第一 TMGI和第一群组签名的集群业务建立请求; 所述 BM-SC接收到所述集群业 务建立请求后,发送所述会话开始请求。 所述会话开始请求会多次转发后到达 所述接收单元 801, 虽然所述会话开始请求中包含有群组签名, 但是其中的转 发过程属于现有技术,这里就不再赘述。所述第一 TMGI和第一群组签名是当 前发起的集群业务所对应群组的 TMGI和群组签名。
发送单元 802, 用于发送群组标识消息, 所述群组标识消息中包括所述第 ― TMGL
所述接收单元 801, 还用于接收用户设备 UE返回的群组通知消息, 所述 群组通知消息包括第二 TMGI和第二群组签名。
这里需要说明的是, 所述群组通知消息的涵盖范围是所述发送单元 802 的信号覆盖范围内, 所有处于所述发送单元 802信号覆盖范围内的 UE均可以 监听到所述群组通知消息。所述群组通知信息携带的第一 TMGI的作用和现有 技术相同, 是为了让空闲状态的 UE可以在监听到所述群组通知信息后, 通过 比对自身所属群组的 TMGI(s)中是否有与所述群组通知消息中 TMGI相同,来 确定是否返回群组通知消息。 同样, 所述群组通知信息也会有可能被并不具有 第一 TMGI的 UE选择接收。 但是, 本发明技术方案的改进点在于, 所述发送 单元 802 并不会将所述会话开始请求中的第一群组签名添加到所述广播消息 中, 而且, UE在确认接收所述广播消息后, 除了需要在返回的群组通知消息 中携带 TMGI以外,还需要携带与返回的 TMGI对应的群组签名,用于识别单 元 804验证所述 UE是否是所述广播消息中的第一 TMGI所对应的群组的一 员, 也就是身份合法性的验证。
识别单元 803, 用于确认所述第二 TMGI 和第二群组签名以及所述第一 TMGI和第一群组签名是否分别一致; 如果分别一致, 识别所述 UE属于所述 会话开始请求中所述第一 TMGI以及第一群组签名所对应的群组。
也就是说,所述识别单元 803除了对 TMGI进行比对以夕卜,还进一步的对 群组签名进行比对, 来验证返回群组通知消息的 UE的身份, 即使有 UE通过 接收群组标识消息的方式获取了其中的第一 TMGI,并将第一 TMGI附加在返 回识别设备的群组通知消息中,该 UE也无法得知对应第一 TMGI的群组签名, 即使返回了 TMGI和群组签名,其返回的群组签名肯定也是错误的,那么这种 情况下所述识别单元 803 在比对第一群组签名和第二群组签名的结果必然是 两者不一致。只有所述识别单元 803确定出第一 TMGI和第二 TMGI—致以及 第一群组签名和第二群组签名也一致的情况下,才会识别返回第二 TMGI和第 二群组签名的 UE为属于所述会话开始请求中所述第一 TMGI以及第一群组签 名所对应的群组的 UE。
当所述识别单元 803识别出 UE是所述会话开始请求中所述第一 TMGI以 及第一群组签名所对应群组的群组成员后, 将为所述 UE分配承载资源, 使得 所述处于空闲状态的 UE重新与所述 eNB建立连接, 转换成连接状态。
完成上述步骤后, eNB会向 MME发送会话开始响应消息。 MME收到 所述会话开始响应消息后, 通过 MBMS-GW 转发给 BM-SC。 BM-SC 向 GCSE Server发送集群业务建立响应消息, 完成集群组呼业务承载的建立。 集群组呼业务承载建立完成后, GCSE Server通过组呼业务承载向群组成员 (其中就包括刚转换成连接状态的所述 UE )发送集群组呼业务消息, 进行 集群业务通信。
在如图 8所对应的实施例的基础上, 可选的, 所述接收单元 801, 还用于接收 MME转发的来自 BM-SC会话开始请求; 所述发送单元 802, 还用于向 UE发送所述广播消息。
在如图 8所对应的实施例的基础上, 可选的, 图 9为本发明实施例提供的 一种集群用户识别的装置结构图,
所述发送单元 802, 还用于通过所述 eNB将所述第一 TMGI向 UE发送; 所示识别单元 803包括接收子单元 8031和确认子单元 8032,
所述接收子单元 8031, 用于接收所述 eNB转发来自 UE的所述群组通知 消息;
所述确认子单元 8032, 用于确认接收的所述群组通知消息中携带的所述 第二 TMGI和第二群组签名和所述集群业务建立请求中的所述第一 TMGI和第 一群组签名是否分别一致; 如果一致, 识别所述 UE属于所述会话开始请求中 所述第一 TMGI以及第一群组签名所对应的群组。
需要说明的是,所述接收单元 801接收会话开始请求的条件是在有集群业 务发起的情况下, 当有集群业务发起时(或者说有处于空闲状态的 UE需要 在所在的一群组中发起集群业务或者该 UE 所在群组中有集群业务要发送 给该 UE时), 也就是在触发所述接收单元 801之前, 在如图 8所对应的实施 例的基础上, 图 10为本发明实施例提供的一种集群用户识别的装置结构图, 如图 10所示:
集群业务建立请求发送单元 1001, 用于在检测到有集群业务发起时, 向 广播-多播业务中心 BM-SC发送包含对应所述集群业务群组的第一 TMGI和第 一群组签名的集群业务建立请求。
开始请求发送单元 1002, 用于接收到所述集群业务建立请求后, 发送所 述会话开始请求。
所述会话开始请求会多次转发后到达所述接收单元 801, 虽然所述会话开 始请求中包含有群组签名,但是其中的转发过程属于现有技术, 这里就不再赘 述。 所述第一 TMGI 和第一群组签名是当前发起的集群业务所对应群组的 TMGI和群组签名。
可选的, 所述 UE具有所注册群组对应的 TMGI和群组签名, 包括: 所述 UE所具有的所述 TMGI以及群组签名是当所述 UE在向所述 GCSE Server进行集群业务注册时, 所述 GCSE Server根据所述集群业务注册的群组 向所述 UE发送的。
通过本实施例可以看出, 在 UE进行注册群组时除了获取 TMGI, 还额 外获取对应的群组签名, 并向识别设备返回包含 TMGI和群组签名的群组 通知消息, 由于群组签名并不没有包含在识别设备发送的广播消息中, 所 以即使有 UE接收所述广播信息, 并获取了消息中的 TMGI, 也无法获取对 应的群组签名, 这样识别设备可以通过比对群组通知消息中的群组签名和 会话开始请求中的群组签名是否相同来有效的识别返回群组通知消息的 UE是否为与所述会话开始请求相关的 UE, 这样就能够有效排除与所述会 话开始请求不相关的非法 UE, 大大节约系统资源。
实施例五
图 11为本发明实施例提供的一种集群用户识别的装置结构图, 所述集群 用户识别装置 1100包括:
获取单元 1101,用于当 MME所管理的 UE在 GCSE Server进行集群业务 注册后, 从所述 GCSE Server得到所述 UE进行所述集群业务注册时获取的 TMGL
这里需要说明的是, 只要所述 MME所管理的 UE没有注册新的群组, 所 述获取单元 1101不需要再被执行的。 只要当 MME所管理的 UE在集群业务 使能服务器 GCSE Server进行集群业务注册后, 所述获取单元 1101 从所述 GCSE Server得到所述 UE进行所述集群业务注册时获取的 TMGI。
第一接收单元 1102, 用于接收来自广播-多播业务中心 BM-SC的会话开 始请求, 所述会话开始请求包括第三 TMGI。
需要说明的是, 所述第一接收单元 1102接收会话开始请求的条件是在有 集群业务发起的情况下, 当有集群业务发起时 (或者说有处于空闲状态的 UE需要在所在的一群组中发起集群业务或者该 UE所在群组中有集群业务 要发送给该 UE时), GCSE Server会向 BM-SC发送包含对应所述集群业务的 第三 TMGI的集群业务建立请求; 所述 BM-SC接收到所述集群业务建立请求 后,发送所述会话开始请求。 所述会话开始请求会多次转发后到达所述第一接 收单元 1102。
识别单元 1103,用于根据所述第三 TMGI从所述所管理的 UE中识别出属 于所述第三 TMGI对应群组的目标 UE。
也就是说, 由于所述获取单元 1101 已经获得了所管理的各个 UE所在群 组的 TMGI, 当所述识别单元 1103获取所述第三 TMGI后, 便可以从所管理 的 UE中确定出具有第三 TMGI的空闲状态的目标 UE, 比如说, MME管理了 10个 UE, 且所述获取单元 1101已经明确了这 10个 UE各自所属的一个或多 个群组的 TMGI信息, 当所述第一接收单元 1102接收到一个会话开始请求, 从所述会话开始请求中获取了第三 TMGI, 所述识别单元 1103根据所述第三 TMGI从所管理的 UE各自的 TMGI中进行比对, 比如说其中有 5个处于空闲 状态的 UE都具有第三 TMGI (也就是说这 5个处于空闲状态的 UE都是第三 TMGI所对应群组的群组成员), 那么所述识别单元 1103就确定出这 5个 UE 为目标 UE。
需要注意的是, 由于确定出的目标 UE最终需要由所述 eNB识别并分 配对应的承载资源,故接下来将对所述 eNB识别目标 UE的方式进行介绍。 在如图 11所对应实施例的基础上,图 12为本发明实施例提供的一种集群用 户识别的装置结构图, 如图 12所示, 还包括:
第一发送单元 1201, 用于通过演进基站 eNB向所述目标 UE发送寻呼消 息, 所述寻呼消息包括所述第二 TMGI和所述目标 UE的 UE标识。
第二接收单元 1202, 用于接收所述目标 UE返回的所述业务请求消息。 第二发送单元 1203, 用于向所述 eNB发送所述目标 UE对应的初始上下 文和第三 TMGI。
需要说明的是, 所述 eNB 虽然传递了寻呼消息, 但是并没有获取能够直 接向目标 UE分配承载资源的必要信息, 所以当所述第二接收单元 1202接收 到的上述目标 UE返回的业务请求消息后, 会通过所述第二发送单元 1203将 返回所述业务请求消息的目标 UE的初始上下文(Initial UE Context ) 以及对 应本次会开开始请求的群组的第三 TMGI发送给所述 eNB, 以使得所述 eNB 能够通过这些信息识别出目标 UE以及所述目标 UE所在的群组, 并以此为所 述目标 UE分配对应所述第三 TMGI的群组的承载资源。
从本实施例中可以看出, MME预先明确所管理的注册为群组成员各个 UE所属群组的 TMGI, 这样当所述 MME接收到会话开始请求时, 根据所 述会话开始请求中的 TMGI确定出所管理的 UE中具有相同 TMGI的 UE, 并仅向确定出来的 UE发送寻呼消息,这样只有通过 MME确认过的 UE才 能收到寻呼消息,杜绝了其他与本次会话开始请求所对应群组不相关的 UE 收到寻呼消息的可能性, 由此 eNB只会为这些由所述 MME确认出的 UE 分配承载资源, 由此大大节约了系统资源。
实施例六
图 13为本发明实施例提供的一种集群用户识别的装置结构图, 所述集群 用户识别装置 1300包括:
第一获取单元 1301, 用于获取识别设备发送的群组标识消息, 所述群组 标识消息中包括所述第一 TMGI。
所述第一获取单元 1301具有所在群组的第二 TMGI和第二群组签名, 所 述第二 TMGI和第二群组签名是所述 UE在进行集群业务注册时获得的,也就 是说, 可选的, 在如图 13所对应的实施例的基础上, 图 14为本发明实施例提 供的一种集群用户识别的装置结构图, 在触发所述第一获取单元 1301之前, 还包括:
第二获取单元 1401, 用于在所述 UE向集群通信业务使能服务器 GCSE Server进行集群业务注册时, 获取所述 GCSE Server发送的第二临时群组标识 TMGI和第二群组签名, 所述第二 TMGI和第二群组签名对应所述 UE注册集 群业务的群组。
发送单元 1302, 用于当所述第一 TMGI和所述 UE 自身的第二 TMGI相 同时, 向所述识别设备返回群组通知消息, 所述群组通知消息包括所述 UE自 身的所述第二 TMGI和第二群组签名。 也就是说, 相比现有技术, 除了返回自身的所述第二 TMGI以外, 还会额 外返回所述第二群组签名以便所述识别设备进一步通过所述第二群组签名验 证所述 UE是否是所述广播消息中的第一 TMGI所对应的群组的一员,也就是 身份合法性的验证。 可选的, 所述发送单元, 还用于向所述识别设备返回所述 群组通知消息,以使得所述识别设备确定确认所述第二 TMGI和第二群组签名 以及所述第一 TMGI和第一群组签名是否分别一致; 如果分别一致, 所述识别 设备识别所述 UE属于所述会话开始请求中所述第一 TMGI以及第一群组签名 所对应的群组。
可见, UE在获取识别设备发送的群组标识消息时, 将会选择返回自身的 第二 TMGI和第二群组签名,以便所述识别设备进一步通过所述第二群组签名 验证所述 UE是否是所述广播消息中的第一 TMGI所对应的群组的一员,这样 就能够有效排除与所述会话开始请求不相关的非法 UE, 大大节约系统资 源。
