Description

获取国际移动用户识别码的方法、 基站和用户设备 技术领域
本发明涉及通信网络领域, 特别涉及一种获取国际移动用户识别码的方法、 基站和用 户设备。 背景技术
IMSI (International Mobile Subscriber Identity, 国际移动用户识别码) 作为移动用户身 份标识, 常用于网络优化领域的用户投诉处理、 VIP用户监控等运维场景, 以用户投诉处理 为例, 当手机用户投诉通话质量有问题时, 根据投诉用户的 IMSI号码和通话时间, 找到对 应的 CHR (Call History Record, 呼叫历史记录), 通过分析 CHR找到影响通话质量的原因, 加以解决, 提升网络服务质量和用户满意度。 IMEI (International Mobile Equipment Identity, 国际移动设备识别码)、 MSISDN (Mobile Subscriber International ISDN Number, 移动用户 国际 ISDN 号) 等信息也常用于类似运维场景。 LTE-SAE ( Long Term Evolution-System Architecture Evolution, 长期演进-系统架构演进) 网络中, UE在附着网络时, 会通过空口 信令把 IMSI信息发送给核心网设备 MME,或者 MME也可发送 IdentityRequest消息给 UE, 要求 UE上报自己的 IMSI。 这些消息通过 NAS (None Access Stratum, 非接入层) 层传递, 对 eNB是不可见的, 即按照目前的设计, MME可以获取到 IMSI信息, 而 eNB是拿不到 UE的 IMSI信息的。
在对现有技术进行分析后, 发明人发现现有技术至少具有如下缺点:
eNB侧都需要从核心网 MME (Mobile Management Entity,移动管理实体)侧获取 IMSI 信息, 使得 eNB对 MME存在依赖性, 如果 eNB、 MME属于同一个厂家提供, 则厂家的 OSS (Operating & Supporting System, 操作支撑系统)可以分别从 eNB获取 CHR数据, 从 MME获取 IMSI信息, 并将这两类数据关联起来, 提供给厂家的网络优化工具完成网络优 化处理。 当 eNB和 MME分属不同厂家时, 生产 eNB的厂家无法从另一厂家的 MME获取 IMSI信息, 导致网络优化工具不可用。 另外将无线侧与核心网侧数据进行关联, 存在处理 复杂, 系统资源消耗大, 且有可能关联不上的问题。 发明内容 本发明实施例提供了一种获取国际移动用户识别码的方法、 基站和用户设备。 所述技 术方案如下:

所述用户设备向所述基站发送 UE身份应答, 所述 UE身份应答携带所述 UE的国际移 动用户识别码 IMSI、 国际移动设备识别码 IMEI和移动用户国际 ISDN号 MSISDN。

Figure imgf000006_0001
在本实施例中, 当用户设备接收到基站发送的 UE身份请求时, 向所述基站发送 UE身 份应答, 所述 UE身份应答携带所述 UE的国际移动用户识别码 IMSI、 国际移动设备识别 码 IMEI和移动用户国际 ISDN号 MSISDN, 基站接收该 UE身份应答后, 将该 IMSI、 IMSI 和 MSISDN对应保存在 CHR中, 后续对网络进行优化时, 可以直观的获得 CHR中用户设 备与 IMSI等之间的关联关系。
本实施例提供的方法, 通过基站向用户设备发送 UE身份请求, 并接收用户设备返回的 UE身份应答,获得 UE的 IMSI, 降低了 eNB对 MME的依赖性,也避免了由于 eNB、 MME 不同厂而造成的获取 IMSI信息困难的情况, 直观的将 UE和 IMSI的关联关系提供给基站, 简化了处理过程。
图 2是本发明实施例提供的一种获取国际移动用户识别码的方法的流程图。 该实施例 的交互双方为基站和用户设备, 参见图 2, 该实施例具体包括:
201、 基站接收 UE的呼叫请求;
本领域技术人员可以获知, 当 UE发起呼叫过程时, 向基站发送呼叫请求, 该呼叫请求 用于请求与指定用户设备建立通信连接。 202、 基站记录该 UE的第一呼叫历史记录 CHR;
在本实施例中, 当基站接收到 UE的呼叫请求时, 记录该 UE的呼叫历史记录。 其中, 呼叫历史记录 CHR (也称 CDR)用于记录一个呼叫的关键历史信息, 包括该呼叫的终端特 征信息、 呼叫建立特征信息、 QoS 相关信息、 呼叫过程行为信息、 呼叫释放相关信息。 由 于每条 CHR记录较长, 为降低采集的数据量, 同时对有价值的数据进行采集, 系统提供控 制功能, 把符合控制条件的记录送到后台进行保存。 系统提供的控制功能可通过过滤不同 的呼叫释放原因进行。
203、 基站向 UE发送 UE身份请求;
在本实施例中,预设了一个新的信令 UE身份请求,该 UE身份请求如步骤 101中所述, 该 UE身份请求用于向 UE请求该 UE的国际移动用户识别码 IMSI、 国际移动设备识别码 IMEI和移动用户国际 ISDN号 MSISDN。
204、 UE向所述基站发送 UE身份应答; 所述 UE身份应答携带所述 UE的国际移动用 户识别码 IMSI、 国际移动设备识别码 IMEI和移动用户国际 ISDN号 MSISDN。
在本实施例中,预设了一个新的信令 UE身份应答,该 UE身份应答如步骤 102中所述, 该 UE身份请求用于响应 UE身份请求。
需要说明的是, UE的呼叫请求触发了基站和 UE之间的信令交互, 该信令交互不涉及 MME, 因此不会由于 MME和 eNB的厂家不同而造成无法互通的情况。
205、 基站将所述携带 UE的 IMSI、 IMEI和 MSISDN的 UE身份应答记录在所述第一 CHR中, 生成第二 CHR;
在本实施例中,第一 CHR为对 UE呼叫过程的描述,包含呼叫过程中的关键历史信息, 而在基站接收到 UE的 IMSI、 IMEI和 MSISDN时, 将该 IMSI、 IMEI和 MSISDN保存在第 一 CHR中, 得到第二 CHR, 使得该第二 CHR中既包括了呼叫过程的关键历史信息, 还包 括了主叫 UE的 IMSI等信息, 将呼叫过程中的关键历史信息、 UE的 IMSI等信息关联了起 来。
进一步地, 在步骤 205中, 基站还将基站所发送的 UE身份请求记录在第一 CHR中, 则所述步骤 205具体包括: 基站将基站发送的 UE身份请求和所述携带 UE的 IMSI、 IMEI 和 MSISDN的 UE身份应答记录在所述第一 CHR中, 生成第二 CHR;
206、 基站将该第二 CHR发送给 OSS;
在本实施例中, 当 OSS对 eNB等设备进行维护或对网络进行优化时, 将该包含了第一 CHR和 UE的 IMSI、 IMEI和 MSISDN的第二 CHR发送给 OSS。 本实施例中所述的 OSS 可以为 OSS侧的数据采集服务器。 207、 OSS根据第二 CHR进行网络优化时,根据该第二 CHR获取第二 CHR对应的 UE 的 IMSI等信息。
IMSI作为用户身份标识, 在网络优化中可用于用户投诉处理等场景, 当用户在使用移 动网络的过程中, 发生掉话、 语音质量不佳等问题, 并投诉到运营商时, 运营商根据用户 的 MSISDN找到其 IMSI, 再根据用户通话的时间、 地点、 IMSI等信息, 从海量的 CHR中 找到跟这一次通话对应的 CHR, 通过对 CHR的分析, 及其它辅助信息, 找到症结所在, 并 作出相应优化。
在本实施例中, OSS无需通过 MME分别获取 CHR和 UE的 IMSI, 而是通过步骤 206 从基站中获取第二 CHR, 省略了 MME对 CHR以及 UE的 IMSI进行关联的过程, 缓解了 传输带宽、 存储和处理能力。 后续当网络优化工具解析第二 CHR记录时, 直接就可知道这 条呼叫历史记录对应的 UE的 IMSI信息。
本实施例提供的方法, 通过基站向用户设备发送 UE身份请求, 并接收用户设备返回的 UE身份应答,获得 UE的 IMSI, 降低了 eNB对 MME的依赖性,也避免了由于 eNB、 MME 不同厂而造成的获取 IMSI信息困难的情况, 直观的将 UE和 IMSI的关联关系提供给基站, 简化了处理过程。 进一步地, 通过省略了现有技术中 MME获取 CHR和 UE的 IMSI, 并将 CHR和 UE的 IMSI进行关联的过程, 缓解了传输带宽、 存储和处理能力, 避免了由于设备 厂商不同而造成的网络优化困难。
在另一实施例中, 步骤 201之前还包括: eNB接收到 OSS发起的小区跟踪请求, 该小 区跟踪请求用于对指定小区中指定 UE进行小区跟踪, 则对于该指定 UE, 如果指定小区中 指定 UE发起一次呼叫请求时, eNB记录该呼叫的跟踪数据,并向 UE发送 UE身份请求 (UE IDENTITY REQUEST), UE返回 UE身份应答 (UE IDENTITY RESPONSE), 将这两个信 令保存在跟踪数据中, 后续当网络优化工具解析跟踪数据时,根据 UE身份应答就可知道本 次呼叫对应的 IMSI信息了。
需要说明的是, 本发明中所述的第二 CHR是指是指一次呼叫过程 (从拨打到挂机)所 产生的各种信令数据的记录、 UE身份请求和 UE身份应答, 也即是该第二 CHR包括第一 CHR、 UE身份请求和 UE身份应答。 与现有技术中的 CHR的不同之处在于, UE身份请求 和 UE身份应答是本发明新增的两条信令。
新增的 eNB向 UE请求 IMSI的信令也属于其中一条信令, 在地位上并无特殊处, 也都 和别的信令一起, 都记录在 CHR里
