卡池的处理方法及装置、卡池系统 技术领域
本申请涉及但不限于通信领域，特别是一种卡池的处理方法及装置、卡池系统。
背景技术
现在到全国各地或者出国旅游、开会等等已是很普遍的现象。出于便于联系和/或节省费用的目的，用户一般会提前修改手机套餐，比如开通国际漫游以方便在国外与家人或朋友联系。但是通过计算证实，漫游套餐的手机流量资费依然很高。
为了解决这一问题，推出了安装SIM卡的卡池设备。用户使用自己的手机可以从网上检测到当前已漫游到哪个国家、哪种制式等相关的信息，然后可以在卡池中选择相关类型的SIM卡进行上网，同时断开自己手机里原有的SIM卡的通信连接，这样就可以节省流量等资费。然而，使用目前的卡池设备，不便于更换SIM卡。

本发明的较佳实施方式
下文中将参考附图并结合实施例来详细说明本申请。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
需要说明的是，本申请的说明书和权利要求书及所述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。
实施例1
在实施例1中，提供了一种卡池系统。
图1是根据本发明实施例的卡池的示意图，如图1所示，该卡池包括：多个卡槽102，其中，多个卡槽中的每个卡槽都布置有设置成检测安装在该卡槽上的客户识别模块SIM卡是否发生热插拔操作的检测引脚。
需要说明的是，每个卡槽上至少布置有一个对应的检测引脚。
实施时，在卡池上电以后，可以根据需要随时对安装在该卡池的任何一个或者多个卡槽上的相应的SIM卡执行热插拔操作，此时，可以根据卡槽上的检测引脚的电平变化情况确定是否执行了热插拔操作。例如，当SIM1卡执行了热插入操作时，可以为插入的SIM卡注册到通信网络。对于注册了通信网络的SIM卡，用户可以找到并使用这些SIM卡。
通过本发明实施例，通过为卡槽设置的所述的检测引脚，使得卡池具有了执行热插拔操作的能力，这给更换SIM卡带来极大的便利。
实施例2
在实施例2中，提供了一种卡池系统。
该卡池系统包括如图1所示的卡池，在该卡池中布置有多个卡槽，其中，多个卡槽中的每个卡槽都布置有设置成检测安装在该卡槽内的SIM卡是否发生热插拔操作的检测引脚。其中，此处的卡池与实施例1中的卡池相同，在此不再赘述。
可选地，所述卡池系统还包括：扩展芯片，设置成扩展卡池中的卡槽数量，与卡池中的卡槽连接。其中，扩展芯片的每一个扩展引脚可以连接至卡池中对应卡槽的检测引脚，或者扩展芯片的每一个扩展引脚可以连接至下一级扩展芯片，该下一级扩展芯片的扩展引脚连接至对应卡槽的检测引脚，此处，该下一级扩展芯片的扩展引脚与对应卡槽的检测引脚的连接方式同其上一级扩展芯片与对应卡槽的检测引脚的连接方式，在此不再赘述。需要说明的是，扩展芯片的扩展引脚与卡槽的连接方式与卡池中的卡槽数量有关，而一个卡池上需要设置的卡槽的数量，可以由提供商根据当地的供需情况确定。这样，通过扩展芯片的扩展卡池中的卡槽的数量，可以根据实际供需情况增大卡池的容量。
可选地，所述扩展芯片包括：一个或者多个一级扩展芯片，每个一级扩展芯片的第一端与控制器(即卡池系统的CPU)连接，每个一级扩展芯片的第二端上设置有N个一级引脚；多个二级扩展芯片，每个一级引脚分别连接所述多个二级扩展芯片中的一个二级扩展芯片的第一端，每个二级扩展芯片的第二端上设置有M个二级引脚，每个二级引脚连接多个卡槽中的一个卡槽的检测引脚。
每个一级扩展芯片的第一端通过总线(如I2C总线)与控制器连接，其中，该总线设置成通过扩展芯片连接卡池系统的CPU及其外围设备(如卡池)，如图2(a)和图2(b)所示，其中图中的总线即为I2C总线，卡池系统的CPU上引出的I2C总线经扩展芯片扩展之后，连接至对应的SIM卡槽上。
在本发明实施例中，所有一级扩展芯片的位数可以相同，也可以不同；所有二级扩展芯片的位数也可以相同，也可以不同。一级扩展芯片的第一端连接的总线可以是从控制器上引出的I2C总线。需要说明的是，各级扩展芯片的位数等于其引脚数目，例如，如果一级扩展芯片有N个一级引脚，则一 级扩展芯片就是N位的扩展芯片；同理，如果二级扩展芯片有M个二级引脚，则二级扩展芯片就是M位的扩展芯片。例如，N可以等于8，M可以等于16。
可选地，卡池系统还包括：第一开关，与收发器连接，该收发器连接在第一开关和控制器之间，第一开关设置成将一路SIM数据信号扩展为(N*M)路SIM数据信号；第二开关，也与收发器连接，该收发器连接在第二开关和控制器之间，第二开关设置成将一路SIM时钟信号扩展为(N*M)路SIM时钟信号；第三开关，也与收发器连接，该收发器连接在第三开关和控制器之间，第三开关设置成将一路SIM重置信号扩展为(N*M)路SIM重置信号。
收发器设置成接收来自卡池系统的CPU的片选信号。各开关都包括多级开关，并且每一级开关作为一组开关可以包括多个开关，例如2个。
以下以一个具体实施例详细阐述本申请的卡池系统：
需要说明的是，在本实施例中，假设卡池系统包括两个一级扩展芯片，每个一级扩展芯片的第一端与控制器(即卡池系统的CPU)连接，每个一级扩展芯片的第二端上设置有N个一级引脚，其中，假设N＝8，这样，此处的每个一级扩展芯片实际上是一个8位的I2C扩展芯片；每个8位的I2C扩展芯片的每个一级引脚分别连接一个二级扩展芯片(即第二级扩展芯片，以下简称为二级扩展芯片)的第一端，每个二级扩展芯片的第二端上设置有M个二级引脚，每个二级引脚连接所述多个卡槽中的一个卡槽的检测引脚。由于两个8位的I2C扩展芯片一共具有16个一级引脚，这样，总共可以连接16个二级扩展芯片，假设每个二级扩展芯片都是一个16位的I2C二级扩展芯片，则经过一、二级扩展芯片扩展之后，总共有16×16个二级引脚。由于每个二级引脚可以连接一个检测引脚，因此，经过所述扩展之后，可以得到一个布置有256个卡槽的卡池系统。
实施时，两个一级扩展芯片的第一端都是连接在控制器(即卡池系统的CPU)上引出的总线(如I2C总线)上的。这样，作为一级扩展芯片的8位的I2C扩展芯片，它的每个引脚都可以分别连接一个作为二级扩展芯片的16位的I2C二级扩展芯片。由于每个16位的I2C二级扩展芯片的每一位扩展引 脚都可以连接到一个SIM卡槽的detect引脚(即检测引脚)上，因此，通过所述的两级扩展芯片，总共能够扩展出256个检测通路，将它们分别连接到对应的SIM卡的卡槽上，就可以支持256个SIM卡。这样，卡池系统具有多个包含了设置成检测安装在对应的卡槽内的客户识别模块SIM卡是否发生热插拔操作的检测引脚的卡槽。换言之，通过该种方式实现的卡池系统支持SIM卡热插拔功能。
因为控制器(即卡池系统的CPU)作为卡池系统的一部分，可以根据中断信息检测哪些卡槽上的SIM卡发生了热插拔操作，哪些卡槽上的SIM卡为可以使用的SIM卡等，进而将检测结果上传给服务器，这样，在终端设备需要使用卡池中的SIM卡时，服务器可以根据检测结果为终端设备选择并提供对应的SIM卡以满足其通信需求。
另外，由于二级扩展芯片的每一个二级引脚连接到一个安装SIM卡的卡槽的detect引脚上，因此可以随时检测对应的detect引脚的电平变化情况，实现了卡池的热插拔功能。
使用所述的卡池，若一个终端设备(如手机)在到国外运行，当获知到所在的国家及其通信制式信息时，就可以从该卡池中选择具有相同信息的SIM卡，然后读取该SIM卡的信息，之后，用户可以选择停止终端设备中的注册到通信网络的SIM卡，进而采用从卡池中选出的所述具有相同信息的SIM卡注册到通信网络，从而能够实现大幅度节省成本的目的。
如图2(a)和图2(b)展示了一种可热插拔SIM卡的卡池系统。其中，图2(a)是根据本发明实施例的卡池系统的主板的结构框图，图2(b)是根据本发明实施例的卡池系统的子板的结构框图，图2(a)所示的主板和图2(b)所示的子板的展示了该实现方法的整个框架。
在所述卡池系统的主板中，从控制器(即卡池系统的CPU)引出四组信号线，分别为：8个连接至收发器的GPIO(General Purpose Input Output，通用输入/输出)片选线，设置成提供片选信号；3个USIM信号线，分别为SIM数据信号USIM_DATA、SIM时钟信号USIM_CLK、SIM重置信号USIM_RESET；I2C总线(即总线)；2个GPIO中断线，设置成传输中断信息。其中，在8个GPIO片选线中，sw1_add0到sw1_add3作为高4位地址 线。sw1_add0作为高位地址线，如果在该位的电平值为0时，sw1_add1、sw1_add2、sw1_add3 3个地址线分别控制3组开关(可以是一级开关)，分别为第一至第三开关，这3组开关的输入分别连接USIM_DATA、USIM_CLK以及USIM_RESET这3个USIM信号线，每个USIM信号线通过开关被扩展输出8通道信号线；同理，当在sw1_add0的电平值为1时，同样分别扩展出这3个USIM信号线对应的8通道信号线，这样，USIM卡的3个USIM信号经过一级扩展之后，就可以分别被扩展成16路通道信号，这样共输出16路通道信号，这16路通道信号在根据同样的扩展原理进行二级扩展，就可以扩展为更多路通道信号，如256路通道信号。卡池系统的CPU通过I2C总线连接2个8位的I2C扩展芯片(即一级扩展芯片)，每个8位的I2C扩展芯片上接入一个GPIO中断线。以上就是主板设计。
在所述卡池系统的子板中，该子板上主要分为两组信号：(1)第一组信号，控制器(即卡池系统的CPU)引出的I2C信号控制一个16位I2C扩展芯片，同时，主板上2个8位的I2C扩展芯片输出的每一路各自接到一个16位的I2C扩展芯片上；(2)第二组信号，主板上的剩下4个地址线sw2_add0、sw2_add1、sw2_add2以及sw2_add3，用同样的方法，主板上分别扩展出的3个USIM信号的16个通道信号中的每一个通路，还能够再次扩展16个通道信号；(3)每个子板上有16个SIM卡的卡槽。从以上对各组信号的解析来看，第一组信号输出了16个detect信号，第二组信号分别输出3个USIM信号的16个通道信号。其中，detect信号、USIM_DATA信号、USIM_CLK信号以及USIM_RESET信号这4个信号分别连接到SIM卡槽上，这样就运行一组中的16个SIM卡。另外，从在所述卡池系统的主板上，还有15组这样的信号，按照前一组信号的实现方法，总共可运行256个SIM卡。
实施例3
在实施例3中，提供了一种卡池的处理方法，需要说明的是，在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的计算机系统中执行，并且，虽然在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤。
图3是根据本发明实施例的卡池的处理方法的流程图，如图3所示，该 方法包括如下步骤：
步骤S302，获取安装在卡池中的卡槽上的客户识别模块SIM卡在发生热插拔操作时所生成的中断信息，其中，卡池包括：多个卡槽，多个卡槽中的每个卡槽都布置有设置成检测安装在该卡槽上的SIM卡是否发生热插拔操作的检测引脚；
步骤S304，根据获取的中断信息确定用于通信的SIM卡。
在卡池上电时，如果热插拔SIM卡，则原本安装了该SIM卡的卡槽的检测引脚上的电平就会发生变化，此时，会产生中断信息，并通过扩展芯片将中断信息反馈给卡池系统的CPU，卡池系统的CPU在接收到中断信息时，可以根据获取的中断信息确定能够通信的SIM卡。
需要说明的是，此处的卡池结构与所述实施例中的任意卡池结构相同，在此不再赘述。
通过本发明实施例，采用为卡池设置热插拔功能，解决了相关技术中的卡池由于不具有热插拔功能而不便于更换SIM卡的技术问题，进而达到了实现卡池的热插拔功能以便于更换的SIM卡的技术效果。
可选地，所述中断信息依据SIM卡发生热插拔操作时，SIM卡对应的卡槽发生电平变化。
通过中断信息可以确定是否发生了热插拔操作，并且在检测到有SIM热插入卡池时，会及时对其进行注册，使其实现通信功能。
可选地，根据获取的中断信息确定用于通信的SIM卡包括：
S2，读取设置成存储卡池中的各个卡槽的卡槽状态的寄存器的值；
S4，记录在获取中断信息之前寄存器的第一记录值，以及依据中断信息对寄存器的值进行更新得到的第二记录值，换言之，第二记录值是发生SIM插拔操作后，寄存器重新记录的各个卡槽的卡槽状态的值；
S6，依据第一记录值以及第二记录值确定发生热插拔操作之后能够通信的SIM卡。
如图4所示，展示了SIM卡的热插拔检测机制。结合图2(a)和图2(b)， 在卡池设备上电时，需要通过I2C总线分别读取2个8位的扩展芯片的寄存器的值，进而读取每个16位的扩展芯片的寄存器的值，通过读取的寄存器的值能够判断出哪个SIM卡槽上有卡，同时保存本次读取的所有寄存器的初始值。
在该卡池设备在工作过程中，如果出现SIM卡的热插拔现象，这时，连接到SIM卡槽的16位扩展芯片的某个引脚的电平就会发生变化，并发出中断信号(即中断信息)。可选地，该中断信号就会通知连接到该16位的扩展芯片的8位扩展芯片，进而通过连接到该8位扩展芯片的主芯片上的GPIO中断信号线将所述中断信号传输给卡池系统的CPU，此时，卡池系统的CPU获取到中断信息后，会通过I2C总线读取8位扩展芯片的I/O管脚以及16位扩展芯片的I/O管脚的寄存器的值，并用当前读出的寄存器的值和上一次读取的寄存器的值(如寄存器的初始值)进行比较，可以判断出是哪个SIM卡槽上发生了电平变化。
在需要使用卡池中SIM卡时，需要通过SIM卡的物理地址，查到想要可用的SIM卡，进而调用底层的接口函数，配置8个GPIO的电平值，从而确定SIM卡的物理地址，这样就可以采用该SIM卡进行通信。
需要说明的是，在本申请中提供了容量为256个SIM卡的卡池的实现方法，在此基础上，可以进行更大数目的SIM卡的扩展，当然为了实现寄存器的读写操作，以及对中断的响应速度，就会对卡池系统的CPU的处理速度提出更高的要求。
通过本申请，实现了可插入256个SIM卡的需求的卡池，能够很方便地满足更多用户在漫游时节省通信成本的需求，从而更好地实现与亲朋间的通信；另外，具有可热插拔的功能可以方便工作人员操作服务器，这样，避免了如果要新插入或者拔出SIM卡，则需要重新对卡池设备上电的操作，进而更方便地服务于用户，有了这样的卡池设备，不管是出国还是在国内，不用再受运营商网络以及地域等诸多因素的限制，从而可以在适应性更强、更灵活、成本更低的环境下，实现跨运营商网络或跨地域实现移动通信网络业务。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到根据所述实施例的方法可借助软件加必需的通用硬件平台的方式来实现，当然也 可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，本申请的技术方案本质上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中，包括若干指令用以使得一台终端设备(可以是手机，计算机，服务器，或者网络设备等)执行本申请各个实施例的方法。
本发明实施例另外提供一种计算机可读存储介质，存储有计算机可执行指令，所述计算机可执行指令被执行时实现所述方法。
实施例4
在实施例4中，提供了一种卡池的处理装置，该装置用于实现所述实施例及可选实施方式，已经进行过说明的不再赘述。如以下所使用的，术语“模块”可以实现预定功能的软件和/或硬件的组合。尽管以下实施例所描述的装置较佳地以软件来实现，但是硬件，或者软件和硬件的组合的实现也是可能并被构想的。
图5是根据本发明可选实施例的卡池的处理装置的示意图，如图5所示，该装置包括：获取单元502，设置成获取安装在卡池中的卡槽上的客户识别模块SIM卡在发生热插拔操作时所生成的中断信息，其中，卡池包括：多个卡槽，多个卡槽中的每个卡槽都布置有设置成检测安装在该卡槽上的SIM卡是否发生热插拔操作的检测引脚；第一确定单元504，设置成根据获取的中断信息确定用于通信的SIM卡。
在卡池上电时，如果对SIM卡执行热插拔操作，则原本安装了该SIM卡的卡槽的检测引脚上的电平就会发生变化，此时，卡池就会产生中断信息，并通过扩展芯片将中断信息反馈给卡池系统的CPU，卡池系统的CPU在接收到中断信息时，可以根据获取的中断信息确定哪些SIM卡能够通信。
需要说明的是，此处的卡池结构同所述实施例中的任意实施方式，在此不再赘述。

如图4所示，展示了SIM卡的热插拔检测机制。结合图2(a)和图2(b)，在卡池设备上电时，需要通过I2C总线分别读取2个8位的扩展芯片的寄存器的值，进而读取每个16位的扩展芯片的寄存器的值，通过读取的寄存器的值能够判断出哪个SIM卡槽上有卡，同时保存本次读取的所有寄存器的初始值。
在该卡池设备在工作过程中，如果出现SIM卡的热插拔现象，这时，连接到SIM卡槽的16位扩展芯片的某个引脚的电平就会发生变化，并发出中断信号(即中断信息)。可选地，该中断信号就会通知连接到该16位的扩展芯片的8位扩展芯片，进而通过连接到该8位扩展芯片的主芯片上的GPIO中断信号线将所述中断信号传输给卡池系统的CPU，此时，卡池系统的CPU获取到中断信息后，会通过I2C总线读取8位扩展芯片的I/O管脚以及16位扩展芯片的I/O管脚的寄存器的值，并用当前读出的寄存器的值和上一次读取的寄存器的值(如寄存器的初始值)进行比较，可以判断出是哪个SIM卡槽上发生了电平变化。以上就是当出现热插拔SIM卡时的检测过程。
在需要使用卡池中SIM卡时，需要通过SIM卡的物理地址，查到想要可用的SIM卡，进而调用底层的接口函数，配置8个GPIO的电平值，这样就可以采用该SIM卡进行通信。
需要说明的是，在本申请中提供了容量为256个SIM卡的卡池的实现方法，在此基础上，可以进行更大数目的SIM卡的扩展，当然为了实现寄存器的读写操作，以及对中断的响应速度，就会对卡池系统的CPU的处理速度提出更高的要求。
