Description

保持客户识别模块卡待机的方法和终端设备 技术领域
本发明涉及通信技术, 尤其涉及一种保持客户识别模块卡待机的方法 和终端设备。 背景技术
客户识别模块 ( Subscriber Identity Module; 以下简称: SIM ) 卡, 也 称为智能卡或用户身份识别卡, SIM卡在一电脑芯片上存储了数字移动电 话用户的信息、 加密的密钥以及用户的电话簿等内容。 SIM卡是带有微处 理器的芯片, 内有 5个模块: 中央处理单元 ( Central Processing Unit; 以 下简称: CPU )、 程序存储器、 工作存储器、 数据存储器和串行通信单元, 这 5个模块集成在一块集成电路中。 SIM卡主要具备如下几种功能:
1 )存储用户相关数据
SIM卡存储的数据可分为四类: 第一类是固定存放的数据。 这类数据 在移动设备( Mobile Equipment; 以下简称: ME )被出售之前由 SIM卡中 心写入, 包括国际移动用户识别号 ( International Mobile Subscriber Identification Number; 以下简称: IMSI ) 、 鉴权密钥 ( Ki )等; 第二类是 暂时存放的有关网络的数据 , 例如: 位置区域识别码 ( Location Area Identification; 以下简称: LAI )、 移动用户暂时识别码 ( Temporary Mobile Subscriber Identity; 以下简称: TMSI ) 、 禁止接入的公共电话网代码等; 第三类是相关的业务代码, 例如: 个人识别码 ( Personal Identification Number; 以下简称: PIN ) 、 解锁码 (PIN Unblocking Key; 以下简称: PUK ) 、 计费费率等; 第四类是电话号码簿, 是手机用户随时输入的电话 号码。
2 ) 用户 PIN的操作和管理
SIM卡本身是通过 PIN来保护的 , PIN是一个四位到八位的个人密码, 只有当用户输入正确的 PIN时, SIM卡才能被启用, 移动终端才能对 SIM 卡进行存取, 也只有 PIN认证通过后, 用户才能上网通话。 3 ) 用户身份鉴权
用户身份鉴权是在网络和 SIM卡之间进行的, 鉴权开始时, 网络产生 一个 128比特的随机数(Rand ) , 经无线电控制信道传送到移动台, SIM 卡依据卡中的密钥 Ki和算法 A3 ,对接收到的 Rand计算出鉴权响应( Signed Response; 以下简称: SRES ) , 并将结果发送给网络端。 而网络端在鉴权 中心查明该用户的密钥 Ki, 用同样的 Rand和算法 A3算出 SRES, 并与收 到的 SRES进行比较, 如果一致, 则鉴权通过。
4 ) SIM卡中的保密算法及密钥
SIM卡中最敏感的数据是保密算法 A3、 A8、 密钥 Ki、 PIN、 PUK和 Kc。 A3和 A8算法是在生产 SIM卡时写入的, 无法读出。 PIN码可由用 户在手机上自己设定, PUK码由运营者持有, Kc 是在加密过程中由 Ki 导出的。
SIM卡是围绕着处理器组织的, 包括以下存储器:
1 )只读存储器( Read Only Memory; 以下简称: ROM ) , ROM为程 序存储器, 典型容量为 16K字节, 含有 SIM卡的开发系统, 算法 A3和 A8 (也可能 A38 ) 是专有使用;
2 ) 电可编程只读存储器 (Electrically Erasable Programmable Read Only; 以下简称: EEPROM ) , EEPROM为数据存储器, 典型容量为 8K 字节, EEPROM存储了全部全球移动通讯系统 ( Global System of Mobile communication; 以下简称: GSM )规范定义域和与专有使用有关的数据;
3 ) 随机存储器( Random Access Memory; 以下简称: RAM ) , RAM 为工作存储器, 其容量还可以减小, 典型值是数百字节, RAM 包含与专 有使用有关的数据。
使用 EEPROM的 SIM卡能保存手机关机时所存储的信息, 并在必要 时提取这些信息。使用者只要保存好 SIM卡, 即使更换手机仍可按同样身 份使用。
虚拟 SIM卡技术是一种直接取消现有的硬件 SIM卡的技术。虚拟 SIM 卡是指移动网络运营商不使用 SIM卡来绑定电话号码和用户的移动终端, 而直接由运营商提供移动电话号码的方式。
但是现有的虚拟 SIM卡技术在同一时刻 ,仅支持虚拟 SIM和硬件 SIM 卡之一待机, 不能支持硬件 SIM卡和虚拟 SIM卡二者同时待机。 也就是 说, 如果移动终端釆用虚拟 SIM卡, 则该移动终端中的硬件 SIM卡将被 停止使用, 这样, 使用该移动终端的用户在使用虚拟 SIM卡时, 就不能使 用硬件 SIM卡进行业务, 也不能基于硬件 SIM卡的标识被联系到, 这就 为用户使用虚拟 SIM卡带来极大的不便。 发明内容 本发明提供一种保持客户识别模块卡待机的方法和终端设备, 以实现 终端设备中基于硬件实现的客户识别模块卡和基于软件实现的客户识另 'J 模块卡同时待机。
本发明第一方面提供一种保持客户识别模块卡待机的方法, 包括: 终端设备接收启动请求, 所述启动请求用于请求所述终端设备中的第 一客户识别模块卡和第二客户识别模块卡同时待机, 所述第一客户识别模 块卡基于软件实现, 所述第二客户识别模块卡基于硬件实现;
所述终端设备调用所述终端设备的操作系统提供的第三方调用接口, 通过所述第三方调用接口的客户识别模块移动设备功能与所述终端设备 中的客户识别模块卡控制模块进行交互, 基于所述第一客户识别模块卡的 数据文件完成所述第一客户识别模块卡的入网过程;
所述终端设备根据所述启动请求同时保持所述第一客户识别模块卡 和已入网的第二客户识别模块卡的待机状态。
本发明另一方面提供一种终端设备包括: 第一客户识别模块卡接口模 块和客户识别模块卡控制模块;
所述第一客户识别模块卡接口模块, 用于接收启动请求, 所述启动请 求用于请求所述终端设备中的第一客户识别模块卡和第二客户识别模块 卡同时待机, 所述第一客户识别模块卡基于软件实现, 所述第二客户识别 模块卡基于硬件实现; 以及调用所述终端设备的操作系统提供的第三方调 用接口, 将所述启动请求发送给所述客户识别模块卡控制模块; 以及通过 所述第三方调用接口的客户识别模块移动设备功能与所述客户识别模块 卡控制模块进行交互, 基于所述第一客户识别模块卡的数据文件完成所述 第一客户识别模块卡的入网过程; 所述客户识别模块卡控制模块, 用于接收所述第一客户识别模块卡接 口模块发送的所述启动请求, 以及在所述第一客户识别模块卡的入网过程 完成之后, 根据所述启动请求同时保持所述第一客户识别模块卡和已入网 的第二客户识别模块卡的待机状态。
本发明的技术效果是: 终端设备接收到请求该终端设备中基于软件实 现的第一客户识别模块卡和基于硬件实现的第二客户识别模块卡同时待 机的启动请求之后, 调用该终端设备的操作系统提供的第三方调用接口, 通过上述第三方调用接口的客户识别模块移动设备功能与终端设备中的 客户识别模块卡控制模块进行交互, 基于上述第一客户识别模块卡的数据 文件完成第一客户识别模块卡的入网过程; 由此可知, 第一客户识别模块 卡的入网过程, 是通过第三方调用接口的客户识别模块移动设备功能与客 户识别模块卡控制模块进行交互完成的, 并未使用第二客户识别模块卡与 客户识别模块卡控制模块之间的接口, 因此第一客户识别模块卡的入网过 程并不影响第二客户识别模块卡的待机状态, 从而终端设备可以根据上述 启动请求同时保持第一客户识别模块卡和已入网的第二客户识别模块卡 的待机状态, 实现终端设备中基于硬件实现的客户识别模块卡和基于软件 实现的客户识别模块卡同时待机, 这样, 即便终端设备使用基于软件实现 的客户识别模块卡, 该终端设备中基于硬件实现的客户识别模块卡也会同 时保持待机状态, 不会被停用, 使用该终端设备的用户仍然可以使用基于 硬件实现的客户识别模块卡进行业务, 仍然可以基于硬件实现的客户识别 模块卡被联系到, 方便了用户的使用。 附图说明

如果使用终端设备的用户在图 4所示的界面上选择某个第一 SIM卡停 用, 例如: 第一 SIM卡 2被停用, 则第一 SIM卡管理模块 34向第一 SIM 卡接口模块 32发送针对上述第一 SIM卡 2的停动请求, 通知第一 SIM卡 接口模块 32停用第一 SIM卡 2。
在具体实现时, 第一 SIM卡接口模块 32和第一 SIM卡管理模块 34 可以在一个程序中实现。
本实施例中, 第一 SIM卡接口模块 32作为运行在终端设备操作系统 之上的应用程序, 第一 SIM卡接口模块 32的应用软件可以从应用商店下 载, 也可以从网络上通过其他方式下载, 本发明对第一 SIM 卡接口模块 32的应用软件的下载方式不作限定。
现有的 SIM卡控制模块 31支持至少两个 SIM卡同时待机, 上述至少 两个 SIM卡一般为基于硬件实现的 SIM卡。如果要求 SIM卡控制模块 31 支持基于软件实现的 SIM卡和基于硬件实现的 SIM卡同时待机, 需要解 决 SIM卡控制模块 31从硬件接口, 切换到软件接口的问题, 该软件接口 由第一 SIM卡接口模块 32提供。
实现 SIM卡控制模块 31与第一 SIM卡接口模块 32之间的接口的方 式可以如图 5所示, 图 5为本发明 SIM卡控制模块与第一 SIM卡接口模 块之间的接口一个实施例的示意图。
在实际部署中, SIM卡控制模块 31 可以是单独的芯片或者是基带模 块 35所在芯片中的一个功能模块。 终端设备的操作系统 (例如: Android 或 iOS ) 通过驱动实现与 SIM卡控制模块 31的通信, 并且终端设备的操 作系统在驱动之上提供第三方调用接口,例如:无线接口层( Radio Interface Layer; 以下简称: RIL )接口。 为了实现第一 SIM卡和第二 SIM卡同时 待机, 需要在图 5所示的 II接口中, 实现 RIL接口中 SIM-ME功能的调 用, 并通告 RIL接口开放 SIM-ME功能, 以使得第一 SIM卡能够被 SIM 卡控制模块 31正常识别和使用。
本实施例中, 需要对 RIL接口增加以下功能:
1 ) 启动、 停止和 /或删除第一 SIM卡的功能;
2 ) SIM-ME功能, 包括数据管理接口 (例如: 通信录的读取和加入) 和用户身份鉴权(例如: 2G入网鉴权、 3G入网鉴权和 3G终端设备对网 络的鉴权等功能) 等。
本实施例中, SIM卡控制模块 31具备同时使用 II和 12接口调用第一 SIM卡接口模块 32和第二 SIM卡 33的能力, 能够实现第一 SIM卡和第 二 SIM卡同时待机。 图 6为本发明 SIM卡控制模块一个实施例的结构示 意图。 如图 6所示, SIM卡控制模块 31包括第一 SIM卡管理接口 311和第 二 SIM卡管理接口 312, 以支持同时与第一 SIM卡和第二 SIM卡的互通。 另外, SIM卡控制模块 31还可以包括 SIM卡管理逻辑 313。
如果 SIM卡控制模块 31集成在基带模块 35所在芯片中,则操作系统 对于驱动、 RIL接口的改动是对基带模块 35所在芯片的改动。
对于 SIM卡控制模块 31或者基带模块 35所在芯片不能满足新需求的 终端设备, 通过第一 SIM卡接口模块 32, 更新驱动, 在新的驱动程序中 劫持 SIM卡控制模块 31内部的 SIM卡管理逻辑 313与第二 SIM卡管理接 口 312,使得 SIM卡管理逻辑 313调用的是第一 SIM卡中的接口, 而不是 第二 SIM卡中的接口, 从而实现第一 SIM卡待机, 但这种方案只能实现 一个 SIM卡 (第一 SIM卡或第二 SIM卡) 的待机。 这种场景下, 在第一 SIM卡管理界面上可以实现基于硬件实现的 SIM卡和基于软件实现的 SIM 卡的启用选择,用户可以通过第一 SIM卡管理界面选择启用基于软件实现 的 SIM卡还是基于硬件实现的 SIM卡, 只能选择其中的一种。
下面对本发明图 3所示实施例中各模块的交互过程进行介绍。
在使用终端设备的用户在第一 SIM卡管理界面上操作 ,选择启用特定 的第一 SIM卡, 例如: 第一 SIM卡 1之后, 第一 SIM卡管理模块 34根据 用户的选择, 向第一 SIM卡接口模块 32发送针对上述第一 SIM卡 1的启 动请求, 请求第一 SIM卡 1和第二 SIM卡同时待机。 其中, 第一 SIM卡 基于软件实现, 第二 SIM卡基于硬件实现。
第 ― SIM卡接口模块 32调用上述终端设备的操作系统在驱动之上提 供的第三方调用接口, 例如: RIL接口, 将上述启动请求发送给 SIM卡控 制模块 31。
然后 SIM卡控制模块 31向第一 SIM卡接口模块 32发送来自网络侧 设备的鉴权请求, 该鉴权请求是 SIM卡控制模块 31通过第三方调用接口 的 SIM-ME功能发送给第一 SIM卡接口模块 32的; 接下来, 第一 SIM卡 接口模块 32读取第一 SIM卡 1的数据文件中的密钥信息, 根据读取的密 钥信息生成鉴权信息, 并将该鉴权信息通过上述第三方调用接口的 SIM-ME功能发送给 SIM卡控制模块 31 , 以供 SIM卡控制模块 31将上述 鉴权信息发送给网络侧设备, 完成第一 SIM卡 1的入网过程。 如果是 3G或长期演进( Long Term Evolution; 以下简称: LTE )网络, 可选地, 终端设备还需要执行对网络的认证过程, 确保终端设备接入使用 该终端设备的用户所期望的可信网络。
完成第一 SIM卡 1的入网过程之后, SIM卡控制模块 31保持第一 SIM 卡 1的待机状态。
另外, 在终端设备开机之后, SIM卡控制模块 31还与第二 SIM卡 33 进行交互, 完成第二 SIM卡 33的入网过程。 具体地, SIM卡控制模块 31 可以接收网络侧设备发送的鉴权请求, 读取第二 SIM卡 33的数据文件中 的密钥信息, 根据读取的密钥信息生成鉴权信息, 并将该鉴权信息发送给 上述网络侧设备, 完成第二 SIM卡 33的入网过程。
最后, SIM卡控制模块 31根据上述启动请求同时保持第一 SIM卡 1 和第二 SIM卡 33的待机状态。
另外, 实现基于软件实现的 SIM卡和基于硬件实现的 SIM卡同时待 机之后, 用户使用时选择哪个 SIM卡发起业务, 比如上网和通话等, 具体 并没有定义, 这可以根据用户、 运营商、 终端设备的具体策略设置, 选择 优先级高的 SIM卡发起, 举例来说, 用户漫游时, 如果用户启用了漫游地 的基于软件实现的 SIM卡, 则在用户漫游期间,对于用户发起的业务优先 使用基于软件实现的 SIM卡, 以节约用户的漫游费用。
本发明提供的保持客户识别模块卡待机的方法和终端设备可以实现 终端设备中基于硬件实现的 SIM卡和基于软件实现的 SIM卡同时待机, 使得用户能够在漫游时方便选择适当的 SIM卡发起业务,有效解决了用户 在漫游时 SIM卡使用上的难题, 降低了 SIM卡的制作成本, 使基于软件 实现的 SIM卡得以高效应用。
本领域技术人员可以理解附图只是一个优选实施例的示意图, 附图中 的模块或流程并不一定是实施本发明所必须的。
本领域技术人员可以理解实施例中的装置中的模块可以按照实施例 描述进行分布于实施例的装置中, 也可以进行相应变化位于不同于本实施 例的一个或多个装置中。 上述实施例的模块可以合并为一个模块, 也可以 进一步拆分成多个子模块。
最后应说明的是: 以上各实施例仅用以说明本发明的技术方案, 而非 对其限制; 尽管参照前述各实施例对本发明进行了详细的说明, 本领域的 普通技术人员应当理解: 其依然可以对前述各实施例所记载的技术方案进 行修改, 或者对其中部分或者全部技术特征进行等同替换; 而这些修改或 者替换, 并不使相应技术方案的本质脱离本发明各实施例技术方案的范
