本发明实施例提供的批量用户信令跟踪的方法与系统,在 OMC上配置 信令跟踪规则, 并发送至 MME; 由 MME将信令跟踪规则进行编码后下发 给 eNodeB; eNodeB再根据信令跟踪规则对接入的 UE进行信令跟踪, 实现 了 MME主控下对批量用户进行信令跟踪,组网与单用户信令跟踪保持了统 一, 无需进行额外的组网设计和功能支持。 附图说明
图 1为本发明实施例批量用户信令跟踪的方法的流程图;
图 2为本发明实施例一的批量用户信令跟踪的方法流程图;
图 3为本发明实施例二的批量用户信令跟踪的方法流程图;
图 4为本发明实施例三的批量用户信令跟踪的方法流程图; 图 5为本发明实施例四的批量用户信令跟踪的方法流程图。 具体实施方式
本发明实施例批量用户信令跟踪的方法的基本思想是: 当需要对批量 用户进行信令跟踪时, 先在 OMC上配置信令跟踪规则, 然后通过 OMC将 信令跟踪规则发送给 MME; MME将信令跟踪规则转化为跟踪信令, 发送 给 eNodeB; eNodeB收到跟踪信令后,存储信令跟踪规则。后续 UE进行接 入时, 进行信令跟踪规则的匹配, 如果匹配成功, 则将信令跟踪规则指定 的 UE信令发送至 MME要求的服务器上对该 UE进行信令跟踪。
具体的, 本发明实施例批量用户信令跟踪的方法如图 1 所示, 包括如 下步驟:
步驟 101 , 在 OMC上配置信令跟踪规则, 并发送至 MME;
步驟 102, MME存储信令跟踪规则, 并进行编码后通过跟踪信令下发 给对应的 eNodeB;
步驟 103 , eNodeB对跟踪信令进行解码后, 存储信令跟踪规则; 步驟 104, UE接入时, eNodeB依据存储的信令跟踪规则对 UE进行信 令跟踪规则匹配, 匹配成功时,将 UE的用户信令发送给信令跟踪输出服务 器, 对 UE进行信令跟踪。
另外, 本发明实施例中还可以实现对批量用户的停止信令跟踪, 具体 的:
在 OMC上配置停止信令跟踪规则, 并发送至 MME;
MME存储停止信令跟踪规则,并进行编码后通过停止跟踪信令下发给 对应的 eNodeB;
eNodeB解码停止跟踪信令, 依据获取的停止信令跟踪规则对自身存储 的信令跟踪规则进行修改或删除。
对于修改后的信令跟踪规则, eNodeB进行本地存储。 如此, UE接入时, 依据修改后的信令跟踪规则执行信令跟踪时, 其实 质是停止了对其中一部分批量用户的跟踪; 显然, 删除信令跟踪后, 就停 止了全部用户的跟踪。
具体的,进行 eNodeB依据获取的停止信令跟踪规则对自身存储的信令 跟踪规则进行修改或删除, 具体为: 如果停止信令跟踪规则包含的停止跟 踪条件与信令跟踪规则包含的跟踪条件部分相同时, 将信令跟踪规则中所 述部分相同的跟踪条件去激活; 如果停止信令跟踪规则仅包含网络标识、 或者包含的停止跟踪条件与信令跟踪规则包含的跟踪条件完全相同, 则删 除信令跟踪规则。
基于保存或修改后的信令跟踪规则对 UE进行信令跟踪规则匹配,且确 定匹配成功, 具体为: UE接入时, eNodeB查询 UE接入的小区对应的所 有跟踪条件, 并将查询到的所有的跟踪条件与自身保存的一条或多条信令 跟踪规则——匹配, 如果查询到的所有的跟踪条件与自身保存的其中一条 信令跟踪规则包含的跟踪条件完全一致时, 确定匹配成功。
上述信令跟踪规则至少包括的跟踪条件为: 网络标识, 表示信令跟踪 的对象为接入指定网络的所有用户; 停止信令跟踪规则至少包括的停止跟 踪条件为: 网络标识, 表示停止信令跟踪的对象为接入指定网络的所有用 户。
进一步地, 信令跟踪规则还包括如下跟踪条件中的一种或几种: 跟踪 区代码(TAC, Tracking Area Code ), MME组标识 ( MME group ID )和 MME码标识( MME Code );停止信令跟踪规则还包括如下停止跟踪条件中 的一种或几种: TAC、 MME group ID和 MME Code。
其中, 信令跟踪规则或停止信令跟踪规则包括 TAC时, 表示信令跟踪 或停止信令跟踪的对象为接入指定跟踪区的所有用户; 信令跟踪规则或停 止信令跟踪规则包括 MME group ID时,表示信令跟踪或停止信令跟踪的对 象为接入指定组的 MME设备的所有用户;信令跟踪规则或停止信令跟踪规 则包括 MME Code时, 表示信令跟踪或停止信令跟踪的对象为接入指定码 的 MME设备的所有用户。
需要指出的是, 如果网络标识为 PLMN网络标识时, 跟踪信令或停止 跟踪信令为 S1信令。
另外, OMC将信令跟踪规则或停止信令跟踪规则发送至 MME时, 信 令跟踪规则或停止信令跟踪规则还包括 eNodeB ID; 相应的 , MME存储信 令跟踪规则或停止信令跟踪规则, 具体为: MME确定 eNodeB ID所指的 eNodeB存在时,将剔除了 eNodeB ID的信令跟踪规则或停止信令跟踪规则 保存至自身的 eNodeB对应的数据区。 本发明实施例的上述信令跟踪方法适用于多种网络类型, 本发明以公 共陆地移动网络( PLMN, Public Land Mobile Network ) 为例进行说明。
为了实现针对 eNodeB下 PLMN用户群的信令跟踪,需要在 OMC上配 置一定的信令跟踪规则。 该信令跟踪规则至少包含 PLMN Identity ( PLMN 网络标识), 在此基础上,信令跟踪规则进一步地,还可以包含 TAC、 MME Group ID、 和 MME Code中的一项或几项。 其中:
信令跟踪规则仅包含 PLMN Identity 时, 表示信令跟踪的对象为指定 PLMN网络的所有用户;
在包含 PLMN Identity的基础上, 信令跟踪规则包含 TAC时, 表示信 令跟踪的对象为指定 PLMN网络下、指定跟踪区域的所有用户; 包含 MME group ID时,表示信令跟踪的对象为指定 PLMN网络下、接入指定组的 MME 设备的所有用户; 包含 MME Code时, 表示信令跟踪的对象为指定 PLMN 网络下、 接入指定码的 MME设备的所有用户。
其中, 关于 MME group ID和 MME Code, 实际的情形是: 一个 MME 设备被划分为多个逻辑 MME,每个逻辑 MME由一个组 ID( MME group ID, 不一定是唯一的)和一个码 ID ( MME Code, 不一定是唯一的)共同表示。 UE在接入一个 MME设备时, 可以接入具体的组和码, 因此, 这里通过组 ID和码 ID来对信令跟踪的用户进行限定。
下面来具体的说明对 PLMN网络用户群实现信令跟踪的过程。
实施例一
本实施例提供了初始链路建立时、 对批量用户进行信令跟踪的过程, 如图 2所示, 包括:
步驟 201 , 需要对某一 eNodeB下指定 PLMN网络( PLMN Identity ) 的批量用户进行信令跟踪时, 首先在 0MC上配置信令跟踪规则, 至少包括 PLMN Identity。 当需要对批量用户作进一步的限定时, 信令跟踪规则还可 以包括 TAC、 MME Group ID和 MME Code中的一项或几项。
配置完成后, 0MC将信令跟踪规则发送给 MME。
需要指出的是, 0MC将信令跟踪规则发送给 MME时, 每条信令跟踪 规则中还包含了 eNodeB ID , 指明了该条信令跟踪规则适用的 eNodeB。
步驟 202, MME接收信令跟踪规则后,根据 eNodeB ID或者 SI口链路 信息确定对应的 eNodeB存在, 那么, MME将信令跟踪规则保存至对应的 eNodeB数据区。
由于一个 MME管理了多个 eNodeB,因此, MME需要按照不同 eNodeB 来存储信令跟踪规则,根据 eNodeB ID,将其保存至对应的 eNodeB数据区。 如此, MME需要向某个 eNodeB下发信令跟踪规则时, 直接到该 eNodeB 的数据区中读取信令跟踪规则、 下发即可。
MME存储的信令跟踪规则中剔除了 eNodeB ID。
步驟 203 , 需要进行初始 S1 链路建立时, eNodeB 向 MME发送 S1 SETUP REQUEST ( SI链路建立请求)信令, 主动发起 S1链路建立请求。 步驟 204 , MME根据 S 1 SETUP REQUEST信令可以确定发起 S 1链路 建立请求的 eNodeB, 此时, MME从自身的该 eNodeB的数据区中读取对 应的信令跟踪规则。
对于一个 eNodeB而言, MME可能存储了其对应的多条信令跟踪规则, 这多条信令跟踪规则之间无交集、 即每条信令跟踪规则限定的信令跟踪对 象不同。
MME读取信令跟踪规则后进行编码,并通过 SI SETUP REPONSE ( SI 链路建立响应 )信令发送给发起 S1链路建立请求的 eNodeB。
在该实施例中, 跟踪信令为 SI SETUP REPONSE信令, 可以对该 SI SETUP REPONSE信令进行扩展, 以携带编码后的信令跟踪规则。 例如, 在该信令中扩展的字段为 Trace Info,其中至少包含了 Trace Activation字段, 用以携带 PLMN Identity; 进一步还可以包含 TAC字段、 MME Group ID字 段和 /或 MME Code字段。
步驟 205 , eNodeB收到 SI SETUP REPONSE信令后进行解码,获取到 信令跟踪规则, 保存到本地。
步驟 206 , UE接入 eNodeB时, 发送信令给 eNodeB。
步驟 207, eNodeB根据 UE接入的小区信息, 查询该小区对应的跟踪 条件: 至少能够查询到该小区对应的 PLMN Identity, 如果存在, 则还能够 查询到该小区对应的 TAC、 MME Group ID和 /或 MME Code。
然后, eNodeB依据查询到的跟踪条件与自身保存的信令跟踪规则进行 匹配, 如果查询到的所有跟踪条件与自身保存的其中一条信令跟踪规则完 全一致, 那么认为匹配成功, eNodeB将该 UE的用户信令发送给 MME指 定的信令跟踪输出服务器进行打印、 即对该 UE进行信令跟踪。 其中, 用户 信令是由信令跟踪规则依据用户所处的网络指定的, 不同网络的用户在此 处对应的用户信令也不同。 例如, 在该实施例中, PLMN 用户对应的用户 信令可以是 S1-MME、 X2、 Uu口信令等。
对于满足该条信令跟踪规则的接入该 eNodeB的所有 UE, 都将对应的 用户信令发送至 MME指定的信令跟踪输出服务器进行打印,如此就实现了 批量用户的信令跟踪。
实施例二
本实施例提供了链路建立完成后, 系统运行期间, 对批量用户进行信 令跟踪的过程, 如图 3所示, 包括:
步驟 301-302同步驟 201-202, 此处不再赘述。
步驟 303 , 根据需要, MME从 eNodeB的数据区中读取信令跟踪规则, 进行编码, 然后通过新增 S1信令, 发送给对应的 eNodeB。
此处, 跟踪信令为新增 S1 信令, 本实施例中为基站跟踪启动 (ENB TRACE START )信令, 其专门用于携带编码后的信令跟踪规则。
该新增 S1信令包括字段 Trace Info, 其中至少包含了 Trace Activation 字段, 用以携带 PLMN Identity; 进一步还可以包含 TAC字段、 MME Group ID字段和 MME Code字段中的一项或多项。
步驟 304, eNodeB收到 ENB TRACE START信令进行解码, 获取到信 令跟踪规则, 保存到本地。
步驟 305-306, 同步驟 206-207, 此处不再赘述。
实施例三
本实施例提供了 eNodeB 在进行批量用户信令跟踪期间, MME指示 eNodeB停止部分或全部用户信令跟踪的处理方法。 eNodeB收到停止批量 用户信令跟踪的信令后, 将信令中携带的停止信令跟踪规则与之前保存的 信令跟踪规则进行对比, 去激活需要停止的信令跟踪规则, 如图 4所示, 包括:
步驟 401 , 需要对某一 eNodeB下指定 PLMN网络( PLMN Identity ) 的批量用户停止信令跟踪时, 首先在 OMC上配置停止信令跟踪规则, 至少 包括 PLMN Identity。当需要对停止信令跟踪的批量用户作进一步的限定时, 信令跟踪规则还可以包括 TAC、 MME Group ID和 MME Code中的一项或 几项。 通过配置停止信令跟踪规则, 限定了停止信令跟踪的用户。
配置完成后, OMC将停止信令跟踪规则发送给 MME。
需要指出的是, OMC将停止信令跟踪规则发送给 MME时, 每条停止 信令跟踪规则中还包含了 eNodeB ID,指明了该条停止信令跟踪规则适用的 eNodeB。
步驟 402, MME接收停止信令跟踪规则后, 根据 eNodeB ID或者 SI 口链路信息确定对应的 eNodeB存在, 那么, MME将停止信令跟踪规则保 存至对应的 eNodeB数据区。
由于一个 MME管理了多个 eNodeB,因此, MME需要按照不同 eNodeB 来存储停止信令跟踪规则, 根据 eNodeB ID, 将其保存至对应的 eNodeB数 据区。 如此, MME需要向某个 eNodeB下发停止信令跟踪规则时, 直接到 该 eNodeB的数据区中读取停止信令跟踪规则、 下发即可。
MME存储的停止信令跟踪规则中剔除了 eNodeB ID。
步驟 403 , 根据需要, MME从 eNodeB的数据区中读取停止信令跟踪 规则, 进行编码, 然后通过新增 S1信令, 发送给对应的 eNodeB。
在该实施例中, 停止跟踪信令为新增 S1信令, 本实施例中为基站停止 跟踪 ( ENB DEACTIVATE TRACE )信令, 其专门用于携带编码后的停止信 令跟踪规则。
该新增 S1信令包含 E-UTRAN Trace ID字段, 该字段为协议规定的当 前信令跟踪的会话标识, 本发明实施例中还用以携带 PLMN Identity; 进一 步还可以包含 TAC字段、 MME Group ID字段和 MME Code字段中的一项 或多项。 步驟 404, eNodeB收到 ENB DEACTIVATE TRACE信令后进行解码, 获取到停止信令跟踪规则, 此时, 需要依据停止信令跟踪规则对存储的信 令跟踪规则进行修改, 具体的: 如果停止信令跟踪规则包含的停止跟踪条 件与信令跟踪规则包含的跟踪条件部分相同时, 那么修改信令跟踪规则、 即将信令跟踪规则中该部分的跟踪条件去激活, 之后本地保存修改后的信 令跟踪规则; 如果停止信令跟踪规则仅包含 PLMN Identity, 或者包含的停 止跟踪条件与信令跟踪规则包含的跟踪条件完全相同, 那么删除该信令跟 踪规则。
如此就可以实现对部分或全部用户的停止信令跟踪。
步驟 405 , UE接入 eNodeB时, 发送信令给 eNodeB。
步驟 406, eNodeB根据 UE接入的小区信息, 查询该小区对应的跟踪 条件: 至少能够查询到该小区对应的 PLMN Identity, 如果存在, 则还能够 查询到该小区对应的 TAC、 MME Group ID和 /或 MME Code。
然后, eNodeB依据查询到的跟踪条件与自身保存的信令跟踪规则进行 匹配, 如果查询到的所有跟踪条件与自身保存的其中一条信令跟踪规则完 全一致, 那么认为匹配成功, eNodeB将该 UE的用户信令发送给 MME指 定的信令跟踪输出服务器进行打印、 即对该 UE进行信令跟踪。如果匹配不 成功, 则不进行或者停止信令跟踪。
实施例四
本实施例提供了 MME指示 eNodeB进行批量用户信令跟踪或停止批量 用户信令跟踪时, eNodeB处理失败时的处理过程, 如图 5所示, 包括: 步驟 501 , MME向 eNodeB下跟踪信令或者停止跟踪信令, 其中携带 编码后的信令跟踪规则或者停止信令跟踪规则。
步驟 502, eNodeB收到跟踪信令或者停止跟踪信令时, 处理失败。 步驟 503, eNodeB向 MME发送跟踪信令失败指示或者停止跟踪信令 失败指示。
此处,跟踪信令失败指示或者停止跟踪信令失败指示为新增的 S1信令, 本实施例中为基站跟踪失败指示 (ENB TRACE FAILURE INDICATION ) 命令, 说明批量用户信令跟踪或停止信令跟踪失败。
该新增 S1信令包括 E-UTRAN Trace ID字段和 Cause字段, 这两个字 段均为协议规定的字段, E-UTRAN Trace ID字段携带了当前信令跟踪会话 标识; Cause字段用于 S1协议中的描述特定操作失败的原因, 该实施例中, 用以携带信令跟踪失败和停止信令跟踪失败的原因。
为了实现上述跟踪方法, 本发明实施例还提供了一种批量用户信令跟 踪的系统, 包括: OMC、 MME和 eNodeB, 其中:
OMC, 用于配置信令跟踪规则, 并下发至 MME;
MME, 用于存储信令跟踪规则, 并进行编码后通过跟踪信令下发给对 应的 eNodeB;

eNodeB, 还用于在确定停止信令跟踪规则包含的停止跟踪条件与信令 跟踪规则包含的跟踪条件部分相同时, 将信令跟踪规则中部分相同的跟踪 条件去激活; 还用于在确定停止信令跟踪规则仅包含网络标识、 或者包含 的停止跟踪条件与信令跟踪规则包含的跟踪条件完全相同, 删除信令跟踪 规则。
eNodeB, 还用于在 UE接入时, 查询 UE接入的小区对应的所有跟踪 条件, 并将查询到的所有的跟踪条件与自身保存的一条或多条信令跟踪规 则——匹配, 如果查询到的所有的跟踪条件与自身保存的其中一条信令跟 踪规则包含的跟踪条件完全一致时, 确定匹配成功。
