Description

一种单IMSI用于多网终端重复注册的方法 技术领域
本发明涉及通讯领域，具体涉及一种单IMSI用于多网终端重复注册的方法。
背景技术
随着移动互联网5G技术的发展，特别是IOT物联网快速进入到全球的生产和生活领域，大量的IOT物联网终端模块在全球范围内流动，移动通信网络的IOT物联网终端的漫游造成标记IOT物联网终端的原厂IMSI号的短缺。
当前的技术发展对同一个IMSI在多个设备的使用进行了各种限制，以防止承载IMSI号的手机卡不被恶意复制，这进一步加大了IMSI号重复使用的技术难度。
对于IOT物联网终端，在出厂的时候，会写入出厂原始IMSI号(后续称为出厂原始IMSI号)，当该终端送达到使用的目的地后(一般为跨国异地，其他国家)，在第一次使用的时候，会采用出厂原始IMSI号进行注册，待注册完成后，该IOT物联网终端将获得一个本地运营商的新本地IMSI号(后续称为本地IMSI号)，那么出厂原始IMSI号将被回收。
IOT物联网终端的大规模出现，跨境漫游的应用场景和当前的技术限制，以及出厂原始IMSI号资源的短缺，推高了IOT物联网终端的应用成本和产品的市场推广。
发明内容
本发明针对目前大规模的IOT物联网终端在跨境漫游方面需要大量的出厂 原始IMSI号进行初始化注册，并且当前的技术方向和实现方式禁止使用同一个出厂原始IMSI号，这样的现状无法满足当前IOT物联网终端在跨境漫游初始化注册的需求。
本发明采用的方法可以有效地将同一个出厂原始IMSI号用在多个IOT物联网终端的同时初始化。具体地，根据本发明的方法有效地解决了多个无线终端同时向归属地发起注册的场景，完成无线终端，特别是IOT物联网终端在跨境漫游的情况下的注册。

参考附图，根据以下对示例性实施例的描述，本发明的其他方面将变得清楚。
具体实施方式
以下，参考附图对根据本发明的方法进行清楚、完整的描述，但是应当理解，以下描述仅仅是示例性的，并且不是要将本发明限制到以下示例性的实施例。
方法概况
根据本发明的方法实现了在大规模IOT物联网终端设备在跨境漫游的时候，多个IOT物联网终端使用同一个出厂原始IMSI号。具体地，根据本发明的方法在3G/4G/5G核心网的用户认证和管理网元HLR/HSS/UDM上，将出厂原始IMSI号与一组对应伪随机列表。
在漫游地，具有同一出厂原始IMSI号的多个IOT物联网终端向出厂原始IMSI的核心网用户认证和管理网元HLR/HSS/UDM发起注册，从而实现了使用同一个出厂原始IMSI完成本地IMSI号码的替换，有效地降低了IMSI资源，大幅度减少了出厂原始IMSI号使用的数量。
应当注意，虽然在以下的描述中以IOT物联网终端作为无线终端的示例进行了描述，但是IOT物联网终端仅仅是示例性的，并且其他类型的无线终端也是可以的。
首先，参考图1，其示出了无线终端漫游地注册实现的架构。首先，在出厂的时候，需要将初始化“出厂原始IMSI”值写入到无线终端中。当无线终端 从出厂地漫游到(主要是跨境)使用地的时候，该无线终端第一次开机，此时，出厂原始IMSI被用于登陆到漫游地的网络，漫游地的HLR/HSS/UDM通过漫游的方式完成接入认证，该无线终端正常进入到漫游地的3G/4G/5G网络中，随后，OTA或者eSIM系统根据用户的漫游的位置信息，将漫游地运营商的本地IMSI写入到无线终端，完成这些操作后，无线终端被重新载入系统，启用漫游地运营商本地IMSI值，享受本地运营商的优惠资费。
在本示例性实施例中，HLR/HSS/UDM中的HLR模块、HSS模块和UDM模块分别是支持不同制式的模块。具体而言，HLR模块是支持3G制式的模块，HSS模块是支持4G制式的模块，并且UDM模块是支持5G制式的模块。
OTA(Over－the－Air Technology)空中下载技术是通过移动通信(GSM或CDMA)的空中接口对SIM卡数据及应用进行远程管理的技术，空中接口可以采用WAP、GPRS、CDMA1X及短消息技术。
而eSIM卡(即Embedded-SIM，嵌入式SIM卡)就是将传统SIM卡直接嵌入到设备芯片上，而不是作为独立的可移除零部件加入设备中，用户无需插入物理SIM卡。这一做法将允许用户更加灵活的选择运营商套餐，或者在无需解锁设备、购买新设备的前提下随时更换运营商。
在本示例性实施例中，将同一类型的无线终端写入相同的“出厂原始IMSI”值和不同的“伪随机CDMA表”的值。具体地，对于多个无线终端，它们可以被写入相同的“出厂原始IMSI”值，此外，针对每个无线终端，其被写入了同一“伪随机CDMA表”的不同的值。也就是说，对于这些被写入了相同的“出厂原始IMSI”值的多个无线终端，其所使用的“伪随机CDMA表”是相同的，所不同的是被分配了不同的值。
该方法采用唯一的“伪随机CDMA表”对出厂的无线终端进行区分，无线 终端在初始化的时候被写入“出厂原始IMSI”值和“伪随机CDMA表”的不同的值，在该无线终端到达漫游地后，开机上电，进行第一次网络注册。此时，无线终端向漫游地网络发起注册。
接着，参考图2，其示出了根据本发明的伪随机CDMA码的存储。具体地，图2示出了网络附属存储NAS的架构，如图所示，16位伪随机CDMA码被存储在网络附属存储NAS的拓展TLV中。
在根据本发明的方法中，对发起注册的消息Attach Request/Reg Request进行扩展。具体地，对于无线终端的用于发起注册的第一个消息，在基本的NAS上增加扩展字段，在扩展字段中，存放”伪随机CDMA表”的值，字节大小为例如16位。应当注意，伪随机CDMA码的位数不限于16位，例如32位也是可以的。
如此，在本发明中，使得同一个IMSI号码(值)对应一个随机列CDMA(m*n)表，从而实现了将单一的IMSI号码(值)扩展到m*n倍(m,n为自然数)。同时，在终端模块在到漫游地后，在发起注册的时候，对发起注册的消息Attach Request/Reg Request也进行扩展，将无线终端的IMSI号码(值)以及对应的一个随机列CDMA值向漫游地的网络发起注册。
图3示出了根据本发明的方法扩展的IMSI号码，其包含出厂原始IMSI和对应的伪随机列表。通过对支持该类型的无线终端归属地的HLR/HSS/UDM进行扩展，增加IMSI号码表与CDMA伪随机表对应的关系数据列表，对IMSI号码表实施扩展。当归属地的HLR/HSS/UDM收到来自漫游地无线终端发起的注册消息(该注册信息包括基本TLV+扩展TLV消息)，对该消息的CDMA伪随机码表进行检查，当该收到某个CDMA伪随机码时候，如果是第一次收到该码，则表明是有跨境漫游地的无线终端开始向归属地进行注册，HLR/HSS/UDM完成匹配 IMSI号码与CDMA伪随机值的正确匹配后，将该IMSI在该终端完成回收，同时对CDMA伪随机列表中对应的CDMA伪随机码设置对应的标志位。后续再收到相同的注册信息包含相同的CDMA伪随机码，表明是非法接入。
以上，已经描述了根据本发明的方法的基本原理，以下针对2G、3G、4G和5G网络进行具体的描述。
2G/3G网络环境下的实现方法
如图4和图5所示，在2G/3G网络环境下，当无线终端(MS)跨境到漫游地时候，第一次开机上电，向当地的网络NodeB和BS无线基站进行注册，在第一个注册消息Attach Request中，通过NAS消息的基本TLV和扩展TLV把IMSI值和CDMA伪随机值传送到归属地的HLR/HSS/UDM网元，支持2G、3G制式的HLR模块完成协议流程处理，读取CDMA伪随机表，如果CDMA匹配成功，完成本次注册。
4G网络环境下的实现方法
如图6和图7所示，无线终端(UE)跨境到漫游地时候，第一次开机上电,向当地的网络eNB无线基站进行注册，在第一个注册消息Attach Request中，通过NAS消息的基本TLV和扩展TLV把IMSI值和CDMA伪随机值传送到归属地的HLR/HSS/UDM网元，支持4G制式的HSS模块完成协议流程处理，读取CDMA伪随机表如果CDMA匹配成功，完成本次注册。
5G网络环境下的实现方法
如图8和图9所示，无线终端(UE)跨境到漫游地时候，第一次开机上电，向当地的网络RAN无线基站进行注册，通过漫游地的在第一个注册消息Attach Request中，通过NAS消息的基本TLV和扩展TLV把IMSI值和CDMA伪随机值传送到归属地的HLR/HSS/UDM网元，支持5G制式的UDM模块完成协议 流程处理，读取CDMA伪随机表如果CDMA匹配成功，完成本次注册。
IMSI替换方法
以上，已经具体参考2G、3G、4G和5G网络描述了根据本发明的方法。接下来，将具体描述漫游地和本地IMSI替换的方法。
如上所述，在批量的无线终端出厂的时候，初始化的“出厂原始IMSI”值被写出到无线终端中。当无线终端从出厂地漫游到(主要是跨境)使用地的时候，该无线终端第一次开机，用出厂原始的IMSI登陆到漫游地的网络，与归属地的HLR/HSS/UDM通过漫游的方式完成接入认证，该无线终端正常进入到当地漫游地的3G/4G/5G网络中，正常进入到无线网络后，OTA或者eSIM系统根据用户的漫游的位置信息，将漫游地运营商的本地IMSI写入到本无线终端，完成操作后，本无线终端重新载入系统，启用漫游地运营商本地IMSI值，享受本地运营商的优惠资费。
如图10所示，在根据本示例性实施例的方法中，将同一类型的无线终端写入相同的“出厂原始IMSI”值和不同的”伪随机CDMA表”的值，该方法采用唯一的“伪随机CDMA表”对出厂的无线终端进行区分。无线终端在初始化的时候，写入“出厂原始IMSI”值和不同的”伪随机CDMA表”的值，在该无线终端到了漫游地后，开机上电，进行第一次网络注册，无线终端发起注册的时候，向漫游地网络发起注册，注册完成后，正常登陆网络后，OTA/eSIM系统写入本地运营商的IMSI号，该终端重新发起注册，该终端享受到本地最优惠的资费登陆使用当地网络。
具体地，在根据本发明的方法中，在IMSI归属地的核心网设备HLR/HSS/UDM上进行扩展，将16位的CDMA伪随机码列表加入其中，每一个IMSI码对应一个CDMA伪随机码列表，从而实现了将同一IMSI码扩展了65535 (2 16-1)倍。在终端出厂时候，写入“出厂原始IMSI”和”CDMA伪随机码”，该终端在第一次注册的时候，将上述2个值通过Attach Request/Reg Requset消息发给归属的核心网设备的HLR/HSS/UDM网元上，该网元对“出厂原始IMSI”认证，同时从”CDMA伪随机码”列表中查阅对应的码值，如果该CDMA码存在，表明该终端模块的第一次认证，并且没有被重复使用，归属的核心网设备的HLR/HSS/UDM网元将该IMSI号的对应的“CDMA伪随机码”列表中的随机码码值去掉，表明该伪随机码已经被使用，通过上述流程，该无线终端的跨境漫游认证通过。
通过该方法，特别是对于IOT模块，能够在第一次上电开机，使用了原始“出厂原始IMSI”后，立即通过OTA/eSIM的方式，用本地运营商的IMSI替换“出厂原始IMSI”。
通过这种方法，“出厂原始IMSI”的使用效率被提高，并且降低了跨境漫游的“出厂原始IMSI”成本。此外，根据本发明的方法将高成本的跨境漫游IMSI号进行重复多次使用，大幅度的节约了“出厂原始IMSI”使用率低的状况。
虽然尽管已经参考示例实施例描述了本公开，但是应该理解，本发明不限于所公开的示例实施例。所附权利要求的范围应被赋予最广泛的解释，以包含所有这些修改和等同的结构和功能。
