一种分组式 MTC设备的识别方法和装置 技术领域
本发明涉及通信领域的机器类通信(MTC )设备分组技术, 尤其涉及 一种分组式 MTC设备的识别方法和装置。 背景技术
作为机器对机器( M2M , Machine to Machine )物联网系统的一项关键 技术, 机器类通信(MTC, Machine-Type Communications ) 已成为当前一 个重要的研究课题。 根据相关研究机构给出的定义, MTC是一种涉及一个 或多个不需要人工干预的网络实体的数据通信。 MTC基于通用的电信网络, 在安保、 跟踪、 测量、 医疗、 远程维护及控制等领域都有着重要的应用前 景。
然而,在运营商的网络中引入 MTC系统往往意味着网络中会新增大量 的通信终端, 即各种 MTC设备, 如传感器、 控制器等, 这势必会导致网络 中大量的资源被 MTC设备占用; 另外, 过多的信令交互也可能引起网络的 拥塞。 为了解决这些问题, 现有技术提出可以将 MTC设备分组处理, 即将 属于同一个用户, 具有某些相同特性的 MTC设备归为一个群组(Group )。 这样, 网络就可以以组为单位对 MTC设备进行控制、 管理或计费等, 从而 减少了很多重复的信令交互, 也节省了网络资源。
网络要处理分组式的 MTC设备, 首先必须知道这些设备是如何分组 的, 即要判断哪些设备是属于一个群组的。 这需要 MTC设备自身携带某种 标识, 同时, 属于同一个群组的设备应该携带一个统一的, 且可以区别于 其它设备的标识。 然而, 在现有技术中还没有一种可以有效的对分组式的 MTC设备进行标识的方法, 从而在 M2M通信过程中也就无法对分组式的 MTC设备进行识别。 发明内容
有鉴于此,本发明的主要目的在于提供一种分组式 MTC设备的识别方 法和装置, 以有效的实现对分组式 MTC设备的群组标识和识别。
为达到上述目的, 本发明的技术方案是这样实现的:
本发明提供了一种分组式机器类通信(MTC )设备的识别方法, 该方 法包括:
获取分组式 MTC设备的国际移动用户识别码( IMSI )或移动台综合业 务数字网号码(MSISDN );
对获取的 IMSI或 MSISDN进行解析得到所述分组式 MTC设备的群组 代码, 并根据所述群组代码识别所述分组式 MTC设备所属的群组。
该方法进一步包括: 根据所述群组代码, 并结合所述 IMSI中的移动国 家码( MCC )和移动网络码 ( MNC )数字段, 或者结合所述 MSISDN中的 国家码(CC )和国内接入码 ( NDC )数字段, 识别所述分组式 MTC设备 所属的群组。
所述群组代码位于 IMSI的移动用户识别号码 ( MSIN )数字段中。 所述群组代码占用 MSIN数字段的前几个数位或任意的几个数位。 所述群组代码位于 MSISDN的用户号码( SN )数字段中。
所述群组代码占用 SN数字段的前几个数位或任意的几个数位。
本发明还提供了一种分组式 MTC设备的识别装置, 该装置包括: 识别码获取单元, 用于获取分组式 MTC设备的 IMSI或 MSISDN; 群组识别单元,用于对获取的 IMSI或 MSISDN进行解析得到所述分组 式 MTC设备的群组代码, 并根据所述群组代码识别所述分组式 MTC设备 所属的群组。
所述群组识别单元进一步用于, 根据所述群组代码, 并结合所述 IMSI 中的 MCC和 MNC数字段, 或者结合所述 MSISDN中的 CC和 NDC数字 段, 识别所述分组式 MTC设备所属的群组。
所述群组代码位于 IMSI的 MSIN数字段中。
所述群组代码占用 MSIN数字段的前几个数位或任意的几个数位。 所述群组代码位于 MSISDN的 SN数字段中。
所述群组代码占用 SN数字段的前几个数位或任意的几个数位。
本发明所提供的一种分组式 MTC设备的识别方法和装置,通过获取分 组式 MTC设备的 IMSI或 MSISDN, 并对获取的 IMSI或 MSISDN进行解 析得到该分组式 MTC设备的群组代码, 然后根据群组代码识别该分组式 MTC设备所属的群组。
通过本发明, 不需要对网络现有标识系统做较大改动, 也不需要修改 网络架构, 而只需要对执行标识解析的网络实体的功能略作加强, 就可以 通过设备标识中的群组代码( IGC或 MGC )来确定 MTC设备所属的群组。 附图说明

下面结合附图和具体实施例对本发明的技术方案进一步详细阐述。 本发明提供了一种对分组式 MTC设备进行标识的方法,使得网络可以 通过这种标识来确定属于某一群组的 MTC设备。 本发明的标识方法, 是在 MTC设备常用的国际移动用户识别码( IMSI, International Mobile Subscriber Identity ) 和移动台综合业务数字网号码 ( MSISDN , Mobile-Station International Integrated-Services-Digital-Network Number )中 ,为分组式 MTC 设备新增群组代码(GC, Group Code ), 具体的:
在 IMSI 标识的移动用户识别号码 ( MSIN , Mobile Subscriber Identification Number )数字段中, 选择若干数位作为分组式 MTC设备的群 组标识, 称为 IMSI群组代码(IGC , IMSI Group Code );
在 MSISDN标识的用户号码( SN, Subscriber Number )数字段中, 选 择若干数位作为分组式 MTC设备的群组标识, 称为 MSISDN群组代码 ( MGC, MSISDN Group Code )„
当然 , 本发明中的群组代码( GC )、 IMSI群组代码( IGC )和 MSISDN 群组代码(MGC )也可以取为其他的名称, 应当理解, 这种名称上的差异 不应构成对本发明保护范围的限定。
实际上, 本发明中分组式 MTC设备的标识仍然釆用常见的 IMSI和 MSISDN, 只是这两个标识中的某几个数位被赋予了新的含义, 即用于指明 某一个特定的群组。
对于在 IMSI中为分组式 MTC设备新增 IGC的实施例, IMSI标识的结 构示意图如图 1所示, 这也是目前通用的 IMSI标识结构。 该标识包含三个 数字段:
移动国家码( MCC , Mobile Country Code ): 用于唯一标识移动用户所 属的国家; 移动网络码( MNC , Mobile Network Code ): 用于标识移动用户的归属 公众陆地移动通信网 ( PLMN, Public Land Mobile Network );
移动用户识别号码( MSIN, Mobile Subscriber Identification Number ): 用于在上述 PLMN网络范围内标识该移动用户。
以上三个数字段中, MCC与 MNC已被赋予了特定含义, 即指明用户 或设备的所属地和网络。 本发明对 MSIN数字段进行处理, 也就是在 MSIN 中选择若干数位作为分组式 MTC设备的群组代码, 用于标识 MTC设备所 属的群组。
在实际应用中, 可以将 MSIN 的前几位作为一个独立的数字段, 作为 群组的 IGC, 如图 2所示; 也可以根据网络中 MSIN资源当前的分配情况 灵活处理, 将 MSIN中任意的几个数位结合起来作为群组的 IGC, 如图 3 所示。
无论釆用图 2还是图 3所示的方案,网络实体在解析 MTC设备的 IMSI 时都必须知道 MTC群组的 IGC以及该 IGC在 MSIN中所处的数位。另夕卜, 目前相关研究机构规定, 同一个 MTC 群组的设备都是属于同一个签约用 户, 因此, 网络在根据 IMSI识别 MTC群组时, 都应是对具有特定 MCC 和 MNC 的 IMSI 进行解析和识别。 显然, 对网络中的任何设备(不仅是 MTC设备 ), 只要其 IMSI中包含一组数字与某一 MTC群组的 IGC相吻合 并且也与该 IGC分布在 MSIN中相同的数位, 而其 MCC和 MNC又与该 MTC群组设备相同, 那么网络实体就会将这一设备看作是属于该 MTC群 组的。 因此, 在为 MTC群组选择 IGC代码及其在 IMSI中所占的数位时 , 以及在为其他设备 (即非分组式 MTC设备 )分配 IMSI时, 都需要注意不 要让网络将一个无关设备误判为属于某一个 MTC群组。
由此可以看出, 为了减少 MTC群组对 IMSI资源的占用, IGC代码的 长度应尽可能取得长一些。 举例来说, 假如网络设定 MSIN是 10位, 某个 MTC群组包含 75个设备, 那么该群组的 IGC就应该取 8位, 因为这样一 来, 具有相同 MCC、 MNC及 IGC (且在相同数位) 的 IMSI将有 100个, 而这 100个 IMSI都将只能由这个 MTC群组使用, 这正好可以容纳群组中 的 75个设备; 如果将该群组的 IGC减少为 7位, 具有相同 MCC、 MNC及 IGC (且在相同数位)的 IMSI就将达到 1000个, 也就是说, 这个群组会占 用 1000个 IMSI, 而其中只有 75个会被使用, 这显然就会造成 IMSI资源 的严重浪费。
对于在 MSISDN中为分组式 MTC设备新增 MGC的实施例, MSISDN 标识的结构示意图如图 4所示, 这也是目前通用的 MSISDN标识结构。 该 标识包含三个数字段:
国家码(CC, Country Code ): 用于标识终端进行注册所在的国家; 国内接入码( NDC , National Destination Code ): 用于标识国家中的一 个编号区域或者一个网络;
用户号码(SN, Subscriber Number ): 用于在上述编号区域或网络范围 内标识该移动终端。
以上三个数字段中, CC与 NDC已被指定用于标明用户或设备的所属 地或网络。 本发明对 SN数字段进行处理, 也就是在 SN中选择若干数位作 为分组式 MTC设备的群组代码, 用于标识 MTC设备所属的群组。
在实际应用中, 可以将 SN的前几位作为一个独立的数字段,作为群组 MGC, 如图 5所示; 也可以根据网络中 SN资源当前的分配情况, 将 SN中 任意的几个数位结合起来作为群组的 MGC, 如图 6所示。
无论釆用图 5还是图 6的方案, 网络实体在解析 MTC设备的 MSISDN 时, 都必须知道 MTC群组的 MGC以及该 MGC在 SN中所处的数位。 另 外, 目前相关研究机构规定, 同一个 MTC群组的设备都是属于同一个签约 用户, 因此, 网络在根据 MSISDN识别 MTC群组时, 都应是对具有特定 CC和 NDC的 MSISDN进行解析和识别。 显然, 对网络中的任何设备 (不 仅是 MTC设备),只要其 MSISDN中包含一组数字与某一 MTC群组的 MGC 相吻合并且也与该 MGC分布在 MSISDN中相同的数位 , 而其 CC和 NDC 又与该 MTC 群组设备相同, 那么网络实体就会将这一设备看作是属于该 MTC群组的。 因此, 在为 MTC群组选择 MGC代码及其在 MSISDN中所 占的数位时, 以及在为其他设备(即非分组式 MTC设备)分配 MSISDN 时, 都需要注意不要让网络将一个无关设备误判为属于某一个 MTC群组。
由此可以看出, 为了减少 MTC群组对 MSISDN资源的占用, MGC代 码的长度应尽可能取得长一些。 举例来说, 假如网络设定 SN是 10位, 某 个 MTC群组包含 75个设备, 那么该群组的 MGC就应该取 8位, 因为这 样一来, 具有相同 CC、 NDC及 MGC (且在相同数位) 的 MSISDN将有 100个, 而这 100个 MSISDN都将只能由这个 MTC群组使用 , 这正好可以 容纳群组中的 75个设备;如果将该群组的 MGC减少为 7位,具有相同 CC、 NDC及 MGC (且在相同数位) 的 MSISDN就将达到 1000个, 也就是说, 这个群组会占用 1000个 MSISDN, 而其中只有 75个会被使用, 这显然就 会造成 MSISDN资源的严重浪费。
在上述对分组式 MTC设备进行标识的方法基础上,本发明还提供了一 种分组式 MTC设备的识别方法, 如图 7所示, 主要包括以下步骤:
步骤 701 , 进行设备识别的网络实体获取分组式 MTC设备的 IMSI或 MSISDN。
步骤 702 , 对获取的 IMSI或 MSISDN进行解析得到该分组式 MTC设 备的群组代码, 并根据群组代码识别该分组式 MTC设备所属的群组。
目前相关研究机构规定, 同一个 MTC群组的设备都是属于同一个签约 用户, 因此, 网络在根据 IMSI识别 MTC群组时, 都应是对具有特定 MCC 和 MNC 的 IMSI 进行解析和识别。 显然, 对网络中的任何设备(不仅是 MTC设备 ), 只要其 IMSI中包含一组数字与某一 MTC群组的 IGC相吻合 并且也与该 IGC分布在 MSIN中相同的数位, 而其 MCC和 MNC又与该 MTC群组设备相同, 那么网络实体就会将这一设备看作是属于该 MTC群 组的。
同样的, 网络在根据 MSISDN识别 MTC群组时, 都应是对具有特定 CC和 NDC的 MSISDN进行解析和识别。 显然, 对网络中的任何设备 (不 仅是 MTC设备),只要其 MSISDN中包含一组数字与某一 MTC群组的 MGC 相吻合并且也与该 MGC分布在 MSISDN中相同的数位 , 而其 CC和 NDC 又与该 MTC 群组设备相同, 那么网络实体就会将这一设备看作是属于该 MTC群组的。
网络实体在解析 MTC设备的 IMSI时, 必须预知 MTC群组的 IGC以 及该 IGC在 MSIN中所处的数位, 进而才能从正确的位置获取到 IGC, 并 识别分组式 MTC设备所属的群组。 网络实体在获取到分组式 MTC设备的 IGC后, 将获取的 IGC与网络实体自身存储的 IGC的信息进行比较, 进而 根据比较结果识别分组式 MTC设备所属的群组。 当然, 这些操作的前提是 网络实体必须知道 MTC群组所属的国家和网络,即 MCC和 MNC的数值。
同样的, 网络实体在解析 MTC设备的 MSISDN时, 必须预知 MTC群 组的 MGC以及该 MGC在 MSISDN中所处的数位,进而才能从正确的位置 获取到 MGC , 并识别分组式 MTC设备所属的群组。 网络实体在获取到分 组式 MTC设备的 MGC后, 将获取的 MGC与网络实体自身存储的 MGC 的信息进行比较, 进而根据比较结果识别分组式 MTC设备所属的群组。 当 然, 这些操作的前提是网络实体必须知道 MTC群组所属的国家和网络, 即 CC和 NDC的数值。
对应上述分组式 MTC 设备的识别方法, 本发明还提供了一种分组式 MTC设备的识别装置, 包括: 识别码获取单元和群组识别单元。 其中, 识 别码获取单元, 用于获取分组式 MTC设备的 IMSI或 MSISDN。 群组识别 单元, 用于对获取的 IMSI或 MSISDN进行解析得到该分组式 MTC设备的 群组代码, 并根据群组代码, 同时结合 IMSI中的 MCC和 MNC数字段或 MSISDN中的 CC和 NDC数字段, 识别该分组式 MTC设备所属的群组。
需要说明的是,群组代码可以位于 IMSI的 MSIN数字段中,占用 MSIN 数字段的前几个数位或任意的几个数位; 也可以位于 MSISDN的 SN数字 段中, 占用 SN数字段的前几个数位或任意的几个数位。
综上所述, 通过本发明, 不需要对网络现有标识系统做较大改动, 也 不需要修改网络架构, 而只需要对执行标识解析的网络实体的功能略作加 强, 就可以通过设备标识中的群组代码( IGC或 MGC )来确定 MTC设备 所属的群组。
以上所述, 仅为本发明的较佳实施例而已, 并非用于限定本发明的保 护范围。
