Description

确定终端在切换时管理标识以及无线信令的方法及设备 技术领域
本发明涉及通信领域, 尤其涉及一种确定终端在切换时管理标识以及 无线信令的方法及设备。 背景技术
随着时分双工长期演进 ( TD_LTE )和频分双工长期演进 ( FDD_LTE ) 技术的不断成熟和完善, 无线技术已经走出实验室, 进入规模试验网建设、 预商用网建设等阶段。 在这个发展过程中, 网络中基站 (小区) 的数量、 用户 (终端) 的数量都大大增加, 同时业务形式更加复杂和多样, 为了分 析定位网络问题、 确定用户行为信息等, 必须收集终端侧和网络侧信息交 互的无线信令, 尤其是对终端在小区切换前后产生的无线信令的完整性和 正确性的采集提出要求。 为了达到这一要求, 必须将终端在源小区与目标 'J、区间切换时的无线信令实现关联, 使得终端在小区切换前后的无线信令 能够被正确地采集。
常用终端在源小区与目标小区间切换时的无线信令关联方式是: 以国 际移动用户识另 ll码 ( International Mobile Subscriber Identification Number, IMSI )作为标识对终端进行信令跟踪, 由于 IMSI作为终端全球唯一的标识 而且终身不变, 因此, 使用其进行终端信令跟踪保证了无线信令的完整性 和正确 <]·生。
当终端在源小区建立业务时, 业务请求消息中可携带 IMSI, 或者, 也 可携带临时识别码 ( Temporary Mobile Subscriber Identity, TMSI )或分组临 时识别码(P_TMSI )。 若业务请求消息中携带的是 IMSI, 则终端在源小区 的无线信令中都将携带该 IMSI, 当终端发生小区切换时, 终端在切换后的 目标小区中的无线信令中也同样携带 IMSI, 因此, 可以根据该 IMSI来收 集该终端在小区切换前后的无线信令。
若业务请求消息中携带的是 TMSI, 则需要将该终端的 TMSI和 IMSI 配合实现关联, 确保无线信令跟踪的正确性和完整性。 例如, 在时分同步 码分多址 ( Time Division-Synchronous Code Division Multiple Access , TD_SCDMA )系统中,终端在源小区建立业务时,在切换消息时使用 TMSI, 且该终端后续在无线资源控制协议 ( Radio Resource Control, RRC )层消息 中也携带 TMSI, 使得终端的 RRC层信令通过 TMSI能够得到关联; 同时, 终端在同一业务建立过程中, 将网络附属存储(Network Attached Storage, NAS )层消息的公用 ID ( Common ID )的内容设置为终端 IMSI, 通过解析 Common ID消息的内容,可将该终端的 IMSI与 TMSI关联起来,利用 IMSI 的全球唯一性以及对于终端的终身不变性, 将终端切换前后的无线信令实 现关联。
随着无线技术的演进, TD_LTE技术的网络结构和技术规范发生了重大 的改变, 如: 电路交换(Circuit Switching, CS )域取消、 无线网络控制器 ( Radio Network Controller, RNC )取消、 协议标准改变等等, 这些新的网 元结构和技术标准的运用, 对于无线信令跟踪带来了很大的影响。 例如, 终端在业务建立过程中 NAS层消息的 Common ID取消, 且业务建立和保 持过程中产生的其他无线信令中 TMSI或 IMSI都不可见, 使得上述利用 IMSI或与 IMSI关联的 TMSI进行小区间切换的无线信令的跟踪手段失效, 当终端发生小区切换时,切换前后的无线信令无法通过上述利用 IMSI或与 IMSI关联的 TMSI方式进行关联, 也就意味着终端在进行切换前后的无线 信令无法进行跟踪。
综上所述, 目前亟待提出一种可应用在不断演进的无线技术中的, 实 现小区间关联切换前后终端无线信令跟踪的方式。 发明内容
本发明实施例提供一种确定终端在切换时管理标识以及无线信令的方 法及设备, 用以解决现有技术中, 无线网络内的终端在进行小区切换时, 无法对该终端的无线信令进行跟踪的问题。
为达到上述目的, 本发明实施例的技术方案是这样实现的:

记录所述终端在本次小区切换时, 在源小区所分配的第一管理标识和 在目标小区所分配的第二管理标识之间的对应关系。
本发明实施例提出一种确定终端的无线信令的方法, 所述确定终端的 无线信令的方法包括:
采集源小区所在源基站处理的无线信令集合以及目标小区所在目标基 站处理的无线信令集合;
根据待查询终端在源小区中的第一管理标识, 从源基站处理的信令中 确定待查询终端的第一无线信令, 以及根据与所述第一管理标识对应的第 二管理标识, 从目标基站处理的信令中确定待查询终端的第二无线信令。
本发明实施例提出一种确定终端在小区间切换时的管理标识的设备, 包括:
第一标识确定模块, 用于在终端从源小区切换至目标小区时, 确定所 述终端在源小区所分配的第一管理标识;
第二标识确定模块, 用于确定所述终端在目标小区所分配的第二管理 标识; 关系建立模块, 用于记录所述终端在本次小区切换时, 在源小区所分 配的第一管理标识和在目标小区所分配的第二管理标识之间的对应关系。
本发明实施例提出一种确定终端的无线信令的设备, 所述确定终端的 无线信令的设备包括:
信令采集模块, 用于采集源小区所在源基站处理的无线信令集合以及 目标小区所在目标基站处理的无线信令集合;
确定模块, 用于根据待查询终端在源小区中的第一管理标识, 从源基 站处理的信令中确定待查询终端的第一无线信令, 以及根据与所述第一管 理标识对应的第二管理标识, 从目标基站处理的信令中确定待查询终端的 第二无线信令。
本发明有益效果如下:
通过本发明实施例的方案, 当终端进行小区切换时, 将源基站为终端 在源小区分配的第一管理标识和目标基站为终端在目标小区分配的第二管 理标识建立对应关系, 由于终端在归属小区内处理的无线信令中携带了该 终端在该小区中的管理标识, 因此, 根据所述对应关系可以将终端在小区 切换前后的无线信令进行关联, 进而可以实现对终端在切换前后的无线信 令进行跟踪。 附图说明

为了实现本发明目的, 本发明实施例提出一种确定终端在切换时管理 标识以及无线信令的方案, 可应用在诸如 TD_LTE和 /或 FDD_LTE等网络 系统中。 在本发明实施例的方案中, 终端在接入的各小区中都被分配管理 标识, 当终端在源小区和目标小区间进行切换时, 将源基站为终端在源小 区分配的第一管理标识和目标基站为终端在目标小区分配的第二管理标识 建立对应关系, 由于终端在小区中的无线信令中将携带终端在该小区中的 管理标识, 因此, 根据所述对应关系可以将终端在小区切换前后的无线信 令进行关联, 进而可以正确、 完整地收集终端在源小区以及目标小区中的 无线信令。
下面结合说明书附图对本发明实施例进行详细说明。
实施例一:
本实施例一提供一种确定终端在小区间切换时的管理标识的方法, 如 图 1 所示, 为本实施例一的方法流程示意图, 本实施例一的实现方式包括 以下几个步驟:
步驟 101 : 在终端从源小区切换至目标小区时,确定终端在源小区的管 理标识, 在这里将终端在源小区中的管理标识记为第一管理标识。
在本发明实施例的方案中, 终端接入一个小区后 (包括终端开机后首 次接入小区或终端从一个小区切换接入至另一个小区的情况), 小区所在基 站将会为该终端分配一个管理标识, 基站可利用该管理标识对终端进行识 别, 终端与基站之间的无线信令中都会携带该管理标识。
步驟 102: 确定所述终端在目标小区所分配的管理标识,在这里将终端 在目标小区中的管理标识记为第二管理标识。
当终端进行小区切换接入目标小区后, 该目标小区所在目标基站将会 为接入的终端分配管理标识。
步驟 101和步驟 102中第一管理标识和第二管理标识都是终端接入小 区所在的基站为终端分配的管理标识, 为了区分终端在不同小区中分配的 管理标识, 这里用第一管理标识和第二管理标识加以区分。
需要说明的是, 本实施例一中终端的小区切换可以是终端在不同基站 间的小区切换, 也可以是在同一基站的不同小区间切换, 不论终端的小区 切换是哪种方式, 在接入目标小区后, 目标小区所在基站都会为该终端新 分配一个管理标识。
步驟 103: 记录终端在本次小区间切换时, 在源小区所分配的第一管理 标识和在目标小区所分配的第二管理标识之间的对应关系。
通过上述实施例一的方案, 建立了终端在进行小区切换前的第一管理 标识和切换后的第二管理标识之间的对应关系, 进而可以利用该对应关系 连接终端在源小区中的无线信令与在目标小区中的无线信令之间的关联, 实现对终端的无线信令的不间断跟踪。
实施例二:
本实施例二是对实施例一各步驟的具体实现方式的详细说明, 如图 2 所示, 本实施例二的方案包括以下步驟:
步驟 201 : 采集源小区所在的源基站向移动管理器 ( Mobility Management Entity, MME )发送的第一切换消息。
在实施例一的步驟 101 中, 需要确定终端在源小区所分配的第一管理 标识, 本实施例二的步驟 201是步驟 101的具体实现方式。 在步驟 201的 方案中, 为了获得终端在源小区所分配的第一管理标识, 当源小区所在源 基站确定终端需要进行 d、区切换时,向 MME发送携带有第一管理标识的第 一切换消息,用于通知 MME当有终端需要进行小区切换,该终端的管理标 识为第一管理标识。
进一步地,源基站向 MME发送的第一切换消息中还可以携带目标基站 标识, 用于通知 MME该终端所要切换的目标基站。 本实施例二的方案中, 源基站可以根据基站间的测量来确定终端切换后的目标基站。
步驟 202: 采集 MME向目标小区所在目标基站发送的第二切换消息。 在步驟 201中, MME已获得源基站发送的第一切换消息, 可从中提取 出终端所要切换的目标基站标识, 进而确定目标基站, 以及还可以提取出 终端在源小区中的第一管理标识。
在本步驟 202中, MME将向目标基站发送第二切换消息, 用于通知目 标基站当前有终端切换至目标基站中的一个小区。
所述第二切换消息中携带了第一临时标识, 该第一临时标识是 MME 为与目标基站协商确定切换的终端而分配的临时标识。
所述第二切换消息还携带了第一通道标识,所述第一通道标识是 MME 为与源基站和目标基站分别协商确定切换的终端而分配的标识。
步驟 203: 采集目标基站向 MME返回的第三切换消息。
在步驟 202中, 目标基站接收到 MME发送的第二切换消息时,确定当 前有终端切换至本地, 则从所述第二切换消息中提取出第一临时标识和第 一通道标识。
目标基站根据提取出的第一临时标识, 将其作为当前切换至本地的终 端在 MME中的标识; 并根据提取出的第一通道标识确定与源基站和 MME 协商切换的终端时使用的标识。
在本步驟 203中,目标基站向 MME返回的第三切换消息中携带了第二 管理标识和从 MME发送的第二切换消息中获取的第二临时标识。本步驟可 以是对实施例一的步驟 102的具体实现, 通过采集所述第三切换消息, 从 中获取终端在目标小区的第二管理标识。
需要说明的是, 步驟 203是对步驟 202发送的第二切换消息的响应, 特殊地, 若在设定时长内, 有多个终端需要切换至目标小区, 则步驟 202 将被执行多次,即 MME在设定时长内向同一目标基站发送了多条第二切换 消息,且每条第二切换消息中都携带了 MME为切换的终端分配的临时标识 和通道标识。 在步驟 203 中, 目标基站需要分别响应各第二切换消息, 因 此, 针对响应的某一个第二切换消息, 需要在作为响应消息的第三切换消 息中携带 MME为终端分配的临时标识,且被响应的第二切换消息中携带的 临时标识与作为对应的响应消息的第三切换消息中的临时标识相同。
例如: 在步驟 202中, MME在设定时长内向目标基站发送了两条第二 切换消息, 其中, 第二切换消息 1中携带的临时标识为 A1B1C1 , 第二切换 消息 2中携带的临时标识为 A2B2C2。则在步驟 203中,目标基站也向 MME 返回两条第三切换消息, 其中:
第三切换消息 1是针对第二切换消息 1的响应消息,在第三切换消息 1 中携带的临时标识为 A1B1C1 ,且第三切换消息 1中携带的第二管理标识为 A1B1C1对应终端的第二管理标识;
第三切换消息 2是针对第二切换消息 2的响应消息,在第三切换消息 2 中携带的临时标识为 A2B2C2,且第三切换消息 2中携带的第二管理标识为 A2B2C2对应终端的第二管理标识。
步驟 204: 采集 MME向源基站返回的第四切换消息。
在步驟 201之后, MME获得了源基站发送的第一切换消息, 则在本步 驟中, MME将向源基站返回第四切换消息。 需要说明的是, MME在步驟 201中获得了第一切换消息后, 可以先执行本步驟 204, 再执行步驟 202和 步驟 203, 也可以将步驟 204和步驟 202并行执行。
MME向源基站返回的第四切换消息中携带了 MME为终端分配的第二 通道标识,以及 MME从第一切换消息中获取的终端在源小区中的第一管理 标识。
需要说明的是, 步驟 204是对步驟 201发送的第一切换消息的响应, 特殊地, 若在设定时长内, 有多个终端需要从源小区进行切换, 则步驟 201 将被执行多次, 即源基站在设定时长内向 MME发送了多条第一切换消息, 且每条第一切换消息中都携带了终端在源小区中的管理标识。则在步驟 204 中, MME需要分别响应各第一切换消息, 因此, 针对响应的某一个第一切 换消息, 需要在作为响应消息的第四切换消息中携带终端在源小区中的管 理标识, 且被响应的第一切换消息中携带的管理标识与作为对应的响应消 息的第四切换消息中的管理标识相同。
例如:在步驟 201中, 源基站在设定时长内向 MME发送了两条第一切 换消息, 其中, 第一切换消息 1中携带的管理标识为 123, 第一切换消息 2 中携带的管理标识为 则在步驟 204中, MME也向源基站返回两条 第四切换消息, 其中:
第四切换消息 1是针对第一切换消息 1的响应消息,在第四切换消息 1 中携带的管理标识为 123, 且第四切换消息 1中携带的第二通道标识为 123 对应终端的第二通道标识;
第四切换消息 2是针对第一切换消息 2的响应消息,在第四切换消息 2 中携带的临时标识为 , 且第四切换消息 2 中携带的第二通道标识为
172737对应终端的第二通道标识。
步驟 205: 判断源基站、 目标基站和 MME三者之间协商的进行切换的 终端是否是同一终端, 若是, 则执行步驟 206; 否则, 输出失败消息。
本步驟 205的具体实现方式为: 第一步: 判断所述第一切换消息中的第一管理标识与所述第四切换消 息中携带的管理标识是否相同。
第二步: 判断所述第二切换请求中的第一临时标识与第三切换请求中 的第二临时标识是否相同。
第三步: 判断所述第二切换消息中的第一通道标识与第四切换消息的 第二通道标识是否相同。
需要说明的是, 以上三步判断过程的先后执行顺序不固定, 可以在步 驟 205中按照上述顺序执行, 也可以在步驟 201~步驟 204的执行过程中, 当判断所需的标识采集获得后即可执行。
第四步: 在以上三个判断结果都为相同时, 确定在第一切换消息中提 取的第一管理标识和第三切换消息中提取的第二管理标识是针对同一终端 的管理标识; 否则, 确定在第一切换消息中提取的第一管理标识和第三切 换消息中提取的第二管理标识不是针对同一终端的管理标识, 输出失败消 在实际的网络环境中, 终端进行小区切换时可以有以下两种情况: 第一种情况, 只有一个终端从源小区离开, 且该唯一终端接入目标小 区;
第二种情况是除第一种情况外的各种切换状态。
针对上述两种情况, 本步驟 205的实现方式为:
针对第一种情况, 可以按照上述三个判断步驟来确定是否是针对同一 终端进行小区切换的协商。 若在设定时长内, 只有一个终端需要从源小区 进行切换, 则在步驟 201中, 源基站向 ΜΜΕ只发送了一条第一切换消息, 因此, 在步驟 204中, ΜΜΕ向源基站也只返回一条第四切换消息, 且第一 切换消息和第四切换消息中携带的管理标识相同; 同时, 若在设定时长内, 只有一个终端切换至目标小区, 则在步驟 202中, ΜΜΕ向目标基站发送一 条第二切换消息, 步驟 203中, 目标基站向 MME返回一条第三切换消息, 且第二切换消息和第三切换消息中携带的临时标识相同。 进一步, 若从源 小区切换出的唯——个终端和切换至目标小区的唯——个终端是同一终 端, 则在第二切换消息中的第一通道标识和第四切换消息中的第二通道标 识相同, 此时, 可以确定源基站、 目标基站和 MME三者之间是针对同一终 端进行的协商, 进而确定第一切换消息中的第一管理标识和第三切换消息 中的第二管理标识是针对同一终端的管理标识, 可执行步驟 206 中建立第 一管理标识和第二管理标识对应关系的操作。
针对第二种情况, 在步驟 201~步驟 204中, 每一个步驟所发出的切换 消息都可能有多条, 此时, 需要针对设定时长内发出的各条切换消息执行 上述三个判断步驟。 若上述三个判断步驟的判断结果都是需要判断的标识 相同, 则执行步驟 206; 若上述三个判断步驟不是每个判断结果都是相同的 情况, 可以将等待一段可容忍的时长, 继续判断在该时长内是否能够有使 三个判断步驟的判断结果都相同的切换消息被发送, 若有, 则也可认为源 基站、 目标基站和 MME之间针对同一终端切换的协商, 若无, 则输出失败 消息。
步驟 206:记录终端在源小区所分配的第一管理标识和在目标小区所分 配的第二管理标识之间的对应关系。
在本步驟中, 当记录所述对应关系后, 可以将该对应关系存储指定的 存储空间内, 同时还记录终端切换前后的源基站标识、 目标基站标识以及 i己录该^应关系的时间。
本步驟 206是对步驟 103的具体实现。
需要说明的是, 本实施例二是以 MME 为源基站和目标基站之间的桥 梁, 建立源基站为终端分配的第一管理标识和目标基站为终端分配的第二 管理标识之间的对应关系,本实施例也不限于利用其他的网元来代替 MME 执行本实施例二的方案。
本实施例一和实施例二的方案可应用在各种协议下进行切换消息的传 输, 下面以 S1接口应用 (S1AP )协议为例, 来分别说明当终端在基站间进 行小区切换以及终端在同一基站的不同小区间切换时, 本实施例一和实施 例二方案的具体实现。
实施例三:
如图 3 所示, 为本发明实施例三中确定终端在切换时管理标识方法的 步驟流程示意图, 本实施例三的终端在不同的基站间进行小区切换, 根据 图 3的描述, 所述方法包括以下步驟:
步驟 301: 终端向源小区发送测量报告, 源小区所在的源基站记录测量 报告中参考信号接收功率( Reference Signal Receiving Power, RSRP )值最 高的小区标识, 并将记录的 RSRP值最高的小区标识作为终端切换后的目 标小区的小区标识。
在本步驟 301 中, 源基站接收终端上报的测量报告并不是实现本发明 目的的必要步驟, 而是优化本发明的优选步驟, 通过本步驟 301 , 源基站可 以获知终端切换后的目标小区, 之后源基站再根据基站间的测量确定终端 切换后的目标基站后, 就可以结合本步驟 301 确定的目标小区最终确定终 端的切换目的地。
步驟 302: 监测源基站与 MME之间进行的信息交互。
本步驟 302的具体实现方式包括但不限于以下子步驟:
第一步: 确定源基站通过 S1接口向 MME发送基于 S1AP协议的越区 切换( HandoverRequireMsg ) 消息, 即实施例二中的第一切换消息。
所述源基站向 MME 发送的 HandoverRequireMsg 消息中有 eNB_UE_SlAP_ID字段和 eNB_ID字段, 所述 eNBl_UE_SlAP_ID字段中 携带的内容是终端在源小区中的第一管理标识。 所述 eNB_ID字段中携带的内容是确定的目标小区的基站标识,在这里 HandoverRequireMsg 消息携带目标小区基站标识不是本发明的必须的内 容,而是优选的内容,有了目标小区的小区标识和目标基站标识,就为 MME 确认终端要进行切换的目标小区提供了准确消息。
假设, 本实施例三中源基站的标识为 eNodeB_l , 该标识可通过
HandoverRequireMsg消息携带至 MME , 也可通过其他方式携带至 MME , 使得 MME 可根据源基站的标识 eNodeB_l 确定终端切换前的源基站。 eNB_UE_SlAP_ID字段中源基站为该终端分配的管理标识为 123, 目标基 站的标 i只为 eNodeB_2。
第二步: 确定 MME通过 S1接口向源基站返回的基于 S1AP协议的越 区命令 ( HandoverCommandMsg ) 消息, 即实施例二中的第四切换消息。
第二步的具体实现方式为:
首先, 当 MME接收来自源基站的越区切换( HandoverRequireMsg )消 息时, 对该消息进行处理。
MME对来自源基站的 HandoverRequireMsg消息进行的处理包括: 记 录 eNB_UE_SlAP_ID字段中的源基站为该终端分配的第一管理标识, 并为 该第一管理标识对应的终端分配通道标识, 即实施例二中的第二通道标识。
然后, 当 MME通过 S1接口向源基站返回基于 S1AP协议的越区命令 ( HandoverCommandMsg )消息时,确定 MME向源基站返回的该消息的内 容。
所述 MME 向源基站发送的 HandoverCommandMsg 消息中有 eNB_UE_SlAP_ID字段和 dl_gTP_TEID字段, 所述 eNB_UE_SlAP_ID字 段中携带的内容是源基站为需要切换的终端分配的第一管理标识; 所述 dl_gTP_TEID字段中携带的内容是 MME为终端分配的通道标识。
步驟 303: 判断源基站与 MME是否针对同一终端的切换进行协商。 在这里 MME返回给源基站的 eNB_UE_SlAP_ID和源基站发给 MME 的 HandoverRequireMsg消息中携带的 eNB_UE_SlAP_ID可以携带相同的 管理标识, 也可以携带不同的管理标识。 若携带的是相同的管理标识, 则 表示源基站与 MME相互对同一终端的切换进行协商; 否则,表示源基站与 MME并不是对同一终端切换的协商。
假设本实施例方案中的判断步驟由 MME内部执行。
步驟 304: 监测 MME与所确定的目标基站之间进行信息交互。
本步驟 304的具体实现方式包括但不限于以下子步驟:
第一步: MME通过 S1接口向目标基站发送基于 S1AP协议的越区请 求消息 ( HandoverRequestMsg ), 即实施例二中的第二切换消息。
所述越区请求消息( HandoverRequestMsg )中携带有 MME为终端分配 的第一临时标识, 该第一临时标识放置在 HandoverRequestMsg 的 mme_UE_SlAP_ID 字段中, 并在 e_RABToBeSetupListHOReq 字段中的 gTP_TEID字段的 data字段内放置为终端分配的第一通道标识。
第二步: 目标基站通过 S1接口向 MME返回基于 S1AP协议的越区请 求确认消息 ( HandoverRequestAcknowledgeMsg ) , 即实施例二中的第三切 换消息。
所述记录越区请求确认消息 ( HandoverRequestAcknowledgeMsg ) 中包 括第 临日于标 i只, 第 临日于标 i只放置在 HandoverRequestAcknowledgeMsg 的 mme_UE_SlAP_ID字段中, 并在 eNB_UE_SlAP_ID字段中放置第二管 理标识。
步驟 305: 判断目标基站与 MME是否针对同一终端的切换进行协商。 在这里 MME发送给目标基站的 mme_UE_Sl AP_ID和目标基站返回给 MME 的 mme_UE_S 1 AP_ID可以携带相同的临时标识,也可以携带不同的 临时标识。若携带的是相同的临时标识,则表示目标基站与 MME相互对同 一终端的切换进行协商; 否则,表示目标基站与 MME并不是对同一终端切 换的协商。
步驟 306: 判断源基站、 目标基站与 MME是否针对同一终端的切换进 行协商。
若步驟 303和 305的判断结果都是标识相同,表示 MME与源基站针对 同一终端的切换进行协商, 与目标基站针对同一终端的切换进行协商, 但 此时, 源基站、 目标基站与 MME三者之间并以不一定是针对同一终端的切 换进行协商。 因此, 本步驟 306 中, 进一步对 MME发送给目标基站的 gTP_TEID字段内的第一通道标识与 MME发送给源基站的 dl_gTP_TEID 字段内的第二通道标识进行比较, 若比较结果为相同, 则表示源基站、 目 标基站和 MME是针对同一终端的切换进行的协商。
步驟 307: 记录源基站向 MME发送的 HandoverRequireMsg 消息中 eNB_UE_S 1 AP_ID 字段内的第一管理标识和目标基站向 MME 返回的 HandoverRequestAcknowledgeMsg的 eNB_UE_SlAP_ID字段内的第二管理 标识的 ^"应关系。
实施例四:
本发明实施例二以终端在同一基站的不同小区间切换为例, 来说明确 定终端在切换时管理标识方法的流程, 本实施例四的方案与实施例三的方 案相同, 区别在于, 源基站可以不向 MME发送目标基站的标识, 而是向 MME发送基站内切换这一事件的标识, 通知 MME终端切换后的目标基站 与源基站是同一基站。
本实施例四也不限于按照实施例三的方式, 源基站将自身的标识作为 目标基站标识发送给 MME。
根据上述实施例一至实施例四的方案, 可以得到同一终端在小区切换 前后, 终端在小区中的管理标识间的对应关系, 进而, 可以通过实施例五 的确定终端无线信令的方式, 实现对终端切换前后无线信令的跟踪。
实施例五:
如图 4所示, 为本实施例五中确定终端的无线信令的方法步驟示意图, 所述方法包括以下步驟:
步驟 501 :采集源小区所在源基站处理的无线信令集合以及目标小区所 在目标基站处理的无线信令集合。
在本实施例的方案中, 后台服务器实时采集网络中各基站处理的无线 信令集合, 包括在实施例一的执行过程中, 后台服务器仍旧不断地采集各 基站处理的无线信令。 当需要跟踪某一待查询终端的无线信令时, 特别是 该待查询终端在某一时间进行的小区切换前后的无线信令跟踪时, 可以首 先确定终端在切换前后的源基站和目标基站, 进而从后台服务器中读取该 源基站处理的无线信令集合和目标基站的无线信令集合。
步驟 502: 根据待查询终端在源小区中的第一管理标识,从源基站处理 的无线信令集合中确定待查询终端的第一无线信令。
在本实施例的方案中, 由于每一无线信令中都携带了一个基站为该无 线信令相关的终端分配的管理标识, 因此, 在本步驟中, 根据待查询终端 在源小区中的第一管理标识, 就可以获得待查询终端的第一无线信令。
具体地, 本步驟 502的实现方式包括但不限于以下两种方式: 方式一:
首先, 确定记录所述待查询终端的第一管理标识和第二管理标识对应 关系的时间。
然后, 根据所述第一无线信令包含的信令生成时间, 从所述第一无线 信令中查找出包含的信令生成时间早于记录所述对应关系的时间, 且与记 录所述对应关系的时间相差小于设定值的无线信令。
这里确定的记录对应关系的时间是一个临界值, 待查询终端在该临界 值时间后已经不是源小区中的终端了, 因此, 在步驟 501 中采集的第一无 线信令中, 晚于该临界值后生成的无线信令不是该待查询终端的无线信令。
最后, 将从第一无线信令中查找出的无线信令(可以是一条或多条) 作为待查询终端在源小区中的无线信令。
方式二:
首先, 确定记录所述待查询终端的第一管理标识和第二管理标识对应 关系的时间。
然后, 根据所述第一无线信令中包含的信令生成时间, 从所述第一无 线信令中查找出信令生成时间早于记录所述对应关系的时间, 且内容是业 务发起的无线信令。
这里查找出的业务发起无线信令是作为业务的起始点, 将该起始点后 的无线信令作为需要跟踪确定的无线信令。
最后, 将第一无线信令中信令生成时间晚于该业务发起无线信令且早 于记录所述对应关系的时间的无线信令作为待查询终端的无线信令。
步驟 503:根据所述对应关系确定待查询终端在目标小区中的第二管理 标识, 从目标基站处理的无线信令集合中确定待查询终端的第二无线信令。
与步驟 502类似地, 本步驟 503的实现方式也包括但不限于以下两种 方式:
方式一:
首先, 确定记录所述待查询终端的第一管理标识和第二管理标识对应 关系的时间。
然后, 根据所述第二无线信令包含的信令生成时间, 从所述第二无线 信令中查找出包含的信令生成时间晚于记录所述对应关系的时间, 且与记 录所述对应关系的时间相差小于设定值的无线信令。
最后, 将从第二无线信令中查找出的无线信令(可以是一条或多条) 作为待查询终端在目标小区中的无线信令。
方式二:
首先, 确定记录所述待查询终端的第一管理标识和第二管理标识对应 关系的时间。
然后, 根据所述第二无线信令中包含的信令生成时间, 从所述第二无 线信令中查找出信令生成时间晚于记录所述对应关系的时间, 且内容是业 务结束的无线信令。
这里查找出的业务结束无线信令是作为业务的结束点, 将该结束点后 的无线信令作为需要跟踪确定的无线信令。
最后, 将第二无线信令中信令生成时间早于该业务结束无线信令且晚 于记录所述对应关系的时间的无线信令作为待查询终端的无线信令。
