Description

电子SIM卡终端的连接管理系统、用户终端及应用程序 技术领域
本发明涉及电子SIM卡终端的网络连接技术，具体地涉及电子SIM卡终端的连接管理系统、用户终端及应用程序。
背景技术
电子SIM卡指不使用传统可插拔SIM卡，通过软件替代传统实体SIM卡，通过电子卡远程下载至终端中(嵌入式UICC卡或者软件模块)并激活使用的方式替代传统可插拔SIM卡的功能，从而达到移动终端不用使用可插拔SIM卡亦可连上蜂窝网络的技术。
对于跨地区使用的移动通信产品，其使用的SIM卡，需要在制造环节将SIM卡以嵌入式UICC卡的方式内置在终端中，这样在生产测试环节就需要测试终端的蜂窝网络连接能力和基于蜂窝网络的应用(如远程诊断、个人娱乐)，在SIM卡销售至某一个地区后，需要切换至该地区当地运营商的配置文件，因此嵌入式SIM(eSIM)技术能够使移动通信产品在销售给终端用户时(或之后)根据国家、地区、用户偏好、网络部署情况选择另外一个运营商并下载与该运营商对应的运营商配置文件至终端上的嵌入式UICC卡上并激活使用该运营商配置文件。
作为一种电子卡远程管理的实现方式，国际标准组织GSMA定义了两套eSIM远程管理技术标准：第一套标准为SGP.01/02，这是面向M2M的嵌入式UICC卡远程管理技术，其建立了一套自上而下的，由后台触发的一种基于嵌入式UICC卡的远程管理技术，每个嵌入式UICC卡内置了一个独一无二的预置运营商配置文件，并与指定的服务器进行绑定；第二套标准为SGP.21/22，这是面向消费电子的SIM远程管理技术，其建立了一套自下 而上的，由终端触发的eSIM远程管理技术。
对于以上提到的两套eSIM远程管理技术标准都存在一定的缺陷，具体来说：
第一套标准SGP.01/02定义了预置运营商配置文件，这类预置运营商配置文件意味着唯一的预置号码，预置唯一号码的问题包括：
(1)物联网终端的数量巨大，每张卡或终端上都预置一个独立并激活的运营商配置文件是一个巨大的码号浪费(IMSI、MSISDN、ICCID)。
(2)在终端、卡的产线上预置一个唯一可用的号码需要在产线上部署额外的工作，增加了生产成本；
(3)对于这些码号而言，需要是一个激活的状态，即需要在网络侧开通保证预置了该号码的终端能够连接蜂窝网络，对于提供该预置号码的运营商而言，网络设备是按照激活用户数、用户容量计算成本的，预置的激活号码越多，运营商成本越高，将转嫁到下游使用预置号码的环节；
(4)SGP.01/02中定义的预制号码需要与某一个SM-SR(eSIM平台)绑定，不够灵活。
第二套标准SGP.21/22尚无明确定义预置运营商配置文件的技术方案。
两套标准仅仅定义了eSIM远程管理的功能，限于在嵌入式UICC卡上实现电子卡功能，没有定义既可以面向移动通信终端又可以面向应用程序的移动连接管理服务，尤其没有定义面向对全球连接性有需求的移动通信终端和应用程序的移动连接管理服务。

本发明实施例的其它特征和优点将在随后的具体实施方式部分予以详细说明。
附图说明
附图是用来提供对本发明实施例的进一步理解，并且构成说明书的一部分，与下面的具体实施方式一起用于解释本发明实施例，但并不构成对本发明实施例的限制。在附图中：
图1是本发明提供的电子SIM卡终端的连接管理系统的框图；
图2是本发明提供的激活连接过程的消息交互图；
图3是本发明提供的即将用尽通知的消息传送图；
图4是本发明提供的继续使用的消息传送图；
图5是本发明提供的使用完成的消息传送图；以及
图6是本发明提供的激活连接过程的流程图。
具体实施方式
以下结合附图对本发明实施例的具体实施方式进行详细说明。应当理解的是，此处所描述的具体实施方式仅用于说明和解释本发明实施例，并不用于限制本发明实施例。
图1是本发明提供的电子SIM卡终端的连接管理系统的框图，如图1所示，该系统包括连接管理模块101、基带处理模块102和连接管理服务器模块103，连接管理模块101用于从预先存储的多个预置运营商配置文件(简称配置文件或Profile)中随机选取一个预置运营商配置文件Profile X；基带处理模块102用于通过Profile X建立连接管理模块101与蜂窝网络之间的临时连接通道；连接管理模块101通过临时连接通道向该连接管理服务器模块103申请并下载当地运营商配置文件Profile A，其中，基带处理模块 102通过Profile A建立与蜂窝网络之间的蜂窝数据连接通道。
在连接管理模块101中存储有多个预置运营商配置文件，例如n个，即预置Profile 1、预置Profile 2、……、预置Profile n。这些预置运营商配置文件是在用户终端生产环节或应用程序生成环节预先写入的，对于写入预置运营商配置文件的技术为本领域的公知常识，于此不予赘述。上述预置运营商配置文件可在全球范围内登录蜂窝网络，即具备数据漫游签约；对于为运营商配置文件进行全球漫游签约为本领域的公知常识，于此不予赘述。需要说明的是，由于预置运营商配置文件具有一定的成本且数量有限，所以预置运营商配置文件的数量比所生产的用户终端的总体数量要少，例如存在10000个用户终端，可能只需要预置50个预置运营商配置文件，也就是说，与现有技术不同的是，不需要一个终端对应一个预置运营商配置文件，在这10000个终端中的任何一个终端的连接管理模块101在需要预置运营商配置文件的时候，可以从这50个预置运营商配置文件中随机选取一个预置运营商配置文件。在本发明中，将这个随机选取的预置运营商配置文件用Profile X表示。
当用户终端开机或终端应用程序发起请求激活移动通信网络时，在连接管理模块101选取到Profile X之后，通知基带处理模块102用这个所选取的Profile X附着网络，基带处理模块102依此指令用Profile X附着至网络，也就是通过Profile X建立临时连接通道，从而就允许连接管理模块101通过临时连接通道向连接管理服务器模块103申请并下载当地Profile，具体就是基带处理模块102通过Profile X附着网络之后向连接管理模块101发送一个反馈消息(例如，OK)，表示临时连接通道建立成功，然后连接管理模块101就可以向连接管理服务器模块103申请并下载当地Profile，本发明中，将当地Profile用Profile A表示。应当理解，基带处理模块102通过Profile A建立与蜂窝网络之间的蜂窝数据连接通道，也就是在终端侧与蜂窝网络之间建立蜂窝数据连接通道。
连接管理模块101下载Profile A的具体过程如下：连接管理模块101向连接管理服务器模块103发送申请Profile A的请求，连接管理服务器模块103根据申请Profile A的请求分配Profile A并向连接管理模块101发送所分配的Profile A。应当理解的是，连接管理模块101向连接管理服务器模块103申请并下载Profile A是利用临时连接通道进行的。
如图1所示，本发明提供的电子SIM卡终端的连接管理系统还包括终端应用模块104，用于通过蜂窝数据连接通道对应用服务器105进行访问。
本领域技术人员应当理解，连接管理模块101与连接管理服务器模块103之间建立连接的最终目的是使终端应用与应用服务器105建立连接，即终端应用能够访问应用服务器105。这里终端应用模块104通过蜂窝数据连接通道对应用服务器105进行访问，实际上是终端应用模块104通过基带处理模块102对应用服务器105进行访问。
在图1中，连接管理模块101、基带处理模块102和终端应用模块104为终端侧的模块。
基带处理模块102通过Profile A建立与蜂窝网络之间的蜂窝数据连接通道包括：连接管理模块101在下载Profile A之后告知基带处理模块102通过Profile A附着网络；以及在基带处理模块102通过Profile A附着网络成功的情况下，蜂窝数据连接通道建立；其中，所述连接管理模块101还用于向连接管理服务器模块103发送激活并使用Profile A消息以通知连接管理服务器模块103已使用Profile A附着网络。
基带处理模块102通过Profile A建立与蜂窝网络之间的蜂窝数据连接通道的具体过程如下：连接管理模块101在下载到Profile A之后，告知基带处理模块102附着网络的运营商配置文件从Profile X切换至Profile A，基带处理模块102在用Profile A成功附着至网络之后向连接管理模块101发送切换成功反馈消息，从而建立蜂窝数据连接通道。连接管理模块101在接收到该切换成功反馈消息之后通过向连接管理服务器模块103发送激 活并使用Profile A消息来通知连接管理服务器模块103已使用Profile A附着网络，连接管理服务器模块103对此进行记录并进行网络状态切换之后向连接管理模块101发送确认激活消息，从而与连接管理服务器模块通信。
本发明提供的电子SIM卡终端的连接管理系统还包括运营商计费模块(图1中未示出)，运营商计费模块用于对终端应用模块104访问应用服务器105的业务量进行计量。
连接管理服务器模块103还用于在向连接管理模块101发送确认激活消息之前向运营商计费模块发送申请业务量的申请消息；其中，运营商计费模块根据该申请消息分配第一业务量并向连接管理服务器模块103发送分配反馈消息，连接管理服务器模块103根据分配反馈消息向连接管理模块101发出确认激活消息。
也就是，在连接管理服务器模块103申请到业务量的时候才会向连接管理模块101发出确认激活消息。分配反馈消息实际上是告知连接管理服务器模块103为其分配了第一业务量。这里的第一业务量可以是时间(例如12小时)，也可以是流量(例如，200M)。
图2是本发明提供的激活连接过程的消息交互图，如图2所示，激活连接过程的消息交互过程如下：
201、终端应用模块向连接管理模块发起激活；
202、连接管理模块从预先存储的多个预置运营商配置文件中随机选取一个预置运营商配置文件Profile X，并激活该Profile X；
203、连接管理模块通知基带处理模块用Profile X附着网络；
204、基带处理模块用Profile X附着网络，开启数据通道，并在附着成功的情况下向连接管理模块反馈OK；至此，建立了连接管理模块与蜂窝网络之间的临时连接通道；
205、连接管理模块通过临时连接通道根据申请消息向连接管理服务器申请当地Profile A，该申请消息包括终端位置、终端型号和终端标识等；
206、连接管理服务器模块根据205中的申请消息分配Profile A；
207、连接管理模块从连接管理服务器模块下载Profile A，这里的下载过程可以通过多种eSIM下载技术实现，例如SGP.01/02、SGP.21/22、或私有的SIM下载技术；
208、连接管理模块告知基带处理模块附着网络的运营商配置文件从Profile X切换至Profile A；
209、基带处理模块用Profile A附着网络并在附着成功的情况下向连接管理模块反馈OK，以指示基带处理模块用Profile A附着网络成功；
210、连接管理模块向连接管理服务器模块发送激活并使用Profile A消息来通知连接管理服务器模块已使用Profile A附着网络，也就是连接管理模块将已使用Profile A附着网络告知连接管理服务器模块；
211、连接管理服务器模块记录并进行网络状态切换；
212、连接管理服务器模块向运营商计费模块申请业务量；
213、运营商计费模块分配第一业务量并向连接管理服务器模块反馈分配反馈消息；
214、连接管理服务器模块向连接管理模块发送确认激活消息；
215、连接管理模块向终端应用模块反馈确认激活消息；
216、终端应用模块利用建立的蜂窝数据连接通道访问应用服务器。
以上阐述了终端应用激活连接从而可以访问应用服务器的过程，下文将对本发明的优选实施方式进行进一步阐述。
本发明中的连接管理服务器模块还用于在接收到激活并使用Profile A消息之后进行网络状态切换，并在进行网络状态切换之后向连接管理模块发送确认激活消息，连接管理模块还用于在向连接管理服务器模块发送激活并使用Profile A消息时开始计时，在计时时间超过第一预定时间的情况下仍未接收到来自连接管理服务器模块的确认激活消息，则重新下载另一Profile A。
结合图2，在210开始计时，如果从210开始超过第一预定时间连接管理服务器模块仍未向连接管理模块发送确认激活消息(图2中的214)，则说明当前的Profile A不可用，连接管理模块向连接管理服务器模块重新下载另一Profile A。
本领域技术人员应当理解，这里也可以设置为在当前的Profile A不可用的情况下，连接管理服务器模块向连接管理模块发送确认不激活消息，从而连接管理模块向连接管理服务器模块重新下载另一Profile A。
本发明中的连接管理模块还用于在连接管理模块选取Profile X时开始计时，在计时时间超过第二预定时间的情况下仍未接收到来自连接管理服务器模块的确认激活消息，则重新选取另一Profile X。
结合图2，在202开始计时，如果从202开始超过第二预定时间连接管理服务器模块仍未向连接管理模块发送确认激活消息(图2中的214)，则说明无法通过当前的Profile X附着至网络，则连接管理模块重新选取另一Profile X。
本发明中的连接管理模块还用于在连接管理模块选取Profile X时开始计时，在计时时间超过第三预定时间的情况下仍未接收到来自基带处理模块的反馈消息，则重新选取另一Profile X。
结合图2，在202开始计时，如果从202开始超过第三预定时间基带处理模块仍未向连接管理模块发送反馈消息(图2中的204)，则说明无法通过当前的Profile X附着至网络，则连接管理模块重新选取另一Profile X。
本发明中的运营商计费模块还用于在计量到所耗费的业务量与第一业务量的差值小于预定业务量阈值的情况下通过连接管理服务器模块向连接管理模块发送即将用尽通知。
这里的第一业务量例如包括时间和/或流量，那么时间对应的预定业务量阈值即为时间阈值，流量对应的预定业务量阈值即为流量阈值，运营商计费模块分配的时间例如可以是12小时，分配的流量例如可以是200M， 以此为例，假设时间阈值为0.5小时，流量阈值为10M，那么在上网时间达到11.5小时(即剩余0.5小时)或者所分配的流量已经用了190M(即剩余10M)的情况下通过连接管理服务器向连接管理模块发送即将用尽通知。当然，也可能出现上网时间为11.5小时且流量已经用了190M的情况。
本发明中的连接管理模块还用于向终端应用模块转发即将用尽通知，以根据终端应用模块的使用反馈消息来申请第二业务量或去激活Profile A。
图3是本发明提供的即将用尽通知的消息传送图，如图3所示，即将用尽通知由运营商计费模块发送至连接管理服务器模块(301)，然后由连接管理服务器模块发送至连接管理模块(302)，再由连接管理模块发送至终端应用模块(303)。
终端应用模块的使用反馈消息可以包括继续使用和使用完成，继续使用表示在第一业务量用尽之后终端应用模块还要继续访问应用服务器，使用完成表示终端应用模块不需要继续访问应用服务器。
图4是本发明提供的继续使用的消息传送图，如图4所示，终端应用模块如果希望在第一业务量用尽之后继续访问应用服务器，则向连接管理模块发出继续使用的使用反馈消息(401)，连接管理模块然后将该继续使用的使用反馈消息发送至连接管理服务器模块(402)，连接管理服务器模块向运营商计费模块转发该继续使用的使用反馈消息(403)，以申请第二业务量，本领域技术人员应当理解，第二业务量的信息应当包括在继续使用的使用反馈消息中。与第一业务量类似，第二业务量也可以包括时间和/或流量，后续过程(例如，何时发送即将用尽通知)与第一业务量类似。第二业务量中的时间可以与第一业务量终端的时间相同或不同，第二业务量中的流量可以与第业务量终端的流量相同或不同。
图5是本发明提供的使用完成的消息传送图，如图5所示，终端应用模块如果不需要继续访问应用服务器，则向连接管理模块发出使用完成的使用反馈消息(501)，然后连接管理模块通知基带处理模块去激活Profile A (502)，与此同时，连接管理模块删除Profile A(503)且连接管理服务器模块回收Profile A(504)，以后续分配给其他终端使用或用于其他方面。
另一方面，在连接管理服务器模块接收到即将用尽通知时开始计时，如果计时时间超过预先设定的第一反馈时间，即超过第一反馈时间仍未接收到终端应用通过连接管理模块发送的继续使用的使用反馈消息，则后续过程与图5所示的使用完成的过程一样，即视为使用完成。
类似地，在连接管理模块接收到即将用尽通知时开始计时，如果计时时间超过预先设定的第二反馈时间，即超过第二反馈时间仍未接收到终端应用发送的继续使用的使用反馈消息，则后续过程与图5所示的使用完成的过程一样，即视为使用完成。
需要说明的是，本发明中所描述的电子SIM卡包括虚拟SIM卡和嵌入式SIM卡(即eSIM卡)。
图6是本发明提供的激活连接过程的流程图，如图6所述，该流程包括：
步骤601，连接管理模块从预先存储的多个运营商配置文件中随机选取一个运营商配置文件，即Profile X，并激活该Profile X；
步骤602，基带处理模块通过步骤601中得到的Profile X附着网络；
步骤603，判断是否超时未接收到反馈OK。具体来说，在步骤602中附着网络成功(即建立了临时连接通道)的情况下，基带处理模块会向连接管理模块反馈OK，以表示附着网络成功，容易理解，如果附着网络不成功，那么基带处理模块也就不会向连接管理模块反馈任何消息，因而这里可以设置一个预定时间，即上文中所描述的第二预定时间，在计时时间(如上文所描述的，在连接管理模块选取Profile X时开始计时)超过第二预定时间连接管理模块仍未接收到反馈OK，则表示附着网络失败。在步骤603中，若超时未接收到反馈OK，即判断结果为是，则返回执行步骤601，重新选取Profile X，若未超时就接收到反馈OK，即判断结果为否，则执行步 骤604。
步骤604，连接管理模块向连接管理服务器模块申请并下载Profile A。
步骤605，基带处理模块通过Profile A附着网络，并在附着网络成功的情况下基带处理模块向连接管理模块发送反馈消息。
步骤606，(在连接管理模块接收到基带处理模块通过Profile A附着网络成功的反馈消息的情况下)连接管理模块向连接管理服务器模块发送激活并使用Profile A消息来通知连接管理服务器模块已使用Profile A附着网络，也就是连接管理模块将已使用Profile A附着网络告知连接管理服务器模块。
步骤607，判断是否超时未接收到确认激活消息。具体来说，在连接管理服务器模块确认激活并使用Profile A的情况下，连接管理服务器模块会向连接管理模块反馈确认激活消息，以指示终端应用模块可以通过蜂窝数据连接通道对应用服务器进行访问，如果连接管理服务器模块没有向连接管理模块反馈确认激活消息，则表示终端应用模块不可以通过蜂窝数据连接通道对应用服务器进行访问，这里可以设置一个预定时间，即上文中所描述的第一预定时间，在计时时间(如上文所描述的，在连接管理模块向连接管理服务器模块发送激活并使用Profile A消息时开始计时)超过第一预定时间连接管理模块仍未接收到反馈确认激活消息，则表示终端应用模块不可以通过蜂窝数据连接通道对应用服务器进行访问。在步骤607中，若超时未接收到确认激活消息，即判断结果为是，则返回执行步骤604，重新申请Profile A，若未超时就接收到确认激活消息，即判断结果为否，则执行步骤608。
步骤608，终端应用模块通过蜂窝数据连接通道对应用服务器进行访问，步骤608是为了使图6所示的流程更加清楚，实际上，在步骤607中连接管理服务器模块向连接管理模块反馈确认激活消息的情况下，就表示终端应用模块能够通过蜂窝数据连接通道对应用服务器进行访问。
