为运营商定制的手机,常常需要应运营商的要求对手机网络进行设置。比如,使定制的手机只支持移动的卡,只支持联通或者电信的卡,其他的卡插入无法正常使用手机。甚至只支持上海移动,只支持移动全球通用户。这类手机一般价格比较低,甚至由运营商免费提供给终端用户。为了保证运营商利益,这时就需要对手机的使用范围进行限制,以保证廉价机和赠送机使用在运营商允许的范围内。sim卡是GSM通信协议和3G通信协议的一部分,而做为sim身份标志的imsi号记录了sim使用的国家,运营商,地区,类型,编号等内容。通过对imsi号的过滤能够实现我们控制手机不被应用在非限制的网络上。当然,这不是绝对的,这是可以破解的,普通的刷机就可以消除这个限制,而且通过修改手机文件的方式也是能够破解的。这样的设置也仅仅是增加了破解的难度,有不少的水货手机就是通过重刷定制机流到市场上的。

SIM的结构十分复杂,拥有本身的处理器,存储器和内存。IMSI号是其身份编号,根据GSM通信协议,他们是全球唯一的编号。IMSI号长度定义为15字节。他们使用8个双字节存储,结构如下,第一个双字节存储长度,8个双字节,后面MCC使用两个双字节中的三个字节,长度为三个字节,MNC使用一个双字节和MCC剩余的那个字节,长度为二到三个字节,然后是NSP一个双字节,后面SIM编号:

下面的是通过屏蔽IMSI号的内容,实现网络锁定,如下图:

知道了原理,改起来就容易了,修改的代码位于modem模块,对于MTK,主要文件是配置custom_nvram_sec.c文件,在这个文件中,一定都封闭完毕,sim初始化通过该文件选择启动:

如果锁中国移动,

{SML_STATE_UNLOCK,SML_RETRY_COUNT_N_CAT,0,0}, 修改为:{SML_STATE_LOCK,0,0,2}, 

该行最后一个参数表示需要锁几个运营商MCC/MNC代码,中国移动有2个,所以填2。

还要在CategoryN code 里填写运营商MCC/MNC代码

 

default值的修改一定要包含在对应的宏包起来,以免影响别的项目。

修改这个default值后要将NV项的版本号#defineNVRAM_EF_SML_LID_VERNO升级

随着手机的普及,大家从非智能机到智能机的转变,从没有操作系统的定制机到智能手机,但唯一没有变的是,手机中的SIM,今天我们就来谈谈手机中 SIM卡相关的内容。在日常生活中,SIM卡就是一张很小的卡片,但这个卡片上却存储了很重要的信息。  同样,Android作为一个智能手机操作系统,也对SIM卡的读取有相关的操作。下面就以Android2.2的SIM卡读写过程进行讲述。


     在上次博客中,有讲述STK,大家可以点这个链接进行查看。android STK 实现原理 (一)。STK与SIM卡是紧密相关的,讲到STK,不可能不说到SIM卡,下面就回到正题。


    在Android的源码中,SIM卡相关的操作,都封装在framework中,



源码所在的目录



 


 


 


   这个文件夹下,存储了所有与手机通讯业务相关的类文件,其中也包括了SIM,STK,CALL, PS数据业务。在上面的图片中,大家可以看到GSM和CDMA两个文件夹,这也是SIM卡相关的,如果插入的是CDMA卡片,就使用CDMA文件夹中的源 码,如果是2G SIM卡,或是3G 联通卡(即GSM/WCDMA)都是使用GSM文件夹。当打开GSM文件夹,可以看到有一个STK 文件夹,里面装的就是上面那个链接里面的源码。如果是2G SIM卡,或是3G 联通卡(即GSM/WCDMA)都是使用GSM文件夹。当打开GSM文件夹,可以看到有一个STK 文件夹,里面装的就是上面那个链接里面的源码。


和SIM卡相关的类主要有以下几个,


IccConstants  (里面记录很多的常量,主要用来存储某个字段在SIM卡上的位置是什么,比如ADN(sim卡上的电话本),6F3A,  FDN(固定拔号 6F3B)),


IccCardStatus(记录SIM卡的状态,如ABSENT, READY,UNKNOW,ETC),


IccFileHandler(这个是用来SIM卡上的RECORD读完后,要处理什么事情),


IccRecords(SIM卡上的文件内容,每一个字段,一个RECORD),


IccProvider(手机上的数据库,读出来的数据全放这),


IccUtils(里面一般全是静态方法,主要用来码制转换),


IccSmsInterfaceManager,IccCard(这个是一个抽象类,会根据上面手机的制式,自动起一个SIMCARD 或者RUIMCARD).


下面就以GSM为例说下读取的过程,


在GSM中就对应上面说的这些会有自己的类,如

SimCard, 

SIMRecords, 

SimPhoneBookInterfaceManager,



1,手机启动时,


根据SIM卡的类型,进入SIMRecords, 开始探测SIM卡的状态,因为,有些SIM卡会设置有PIN码,如果SIM卡有PIN码的话,手机会弹出输入PIN码的框,等待用户进行解码,注意,这个 时候,如果PIN码如果没有解的话,手机是不会去读SIM卡的,因为,读SIM卡时,必须通过PIN才能去读,只有一些比较特殊的字段,可以不用,比如 ECC 也就是紧急呼叫号码(一般存在卡上,运营商定制的)。同时,这PIN码未解的情况,手机中SIM卡的状态也是PIN_REQURIED_BLOCK,


2,当解完PIN码,或是手机没有设置PIN码,这时,手机的会探测到SIM是READY的状态,手机只有检测到SIM READY,才会发出读卡的请求。


[java] view plaincopy 

1. case EVENT_SIM_READY:

这里,手机开始读卡第一个是


IMSI(International Mobile SubscriberIdentification Number)主要用来查找运营商的网络,里面有MCC,MNC,


ICCID(Integrate circuit card identity)唯一标识一个移动用户。


然后,大家可以看到有很多类似这样的函数调用iccFh.loadEFTransparent,这个就是调用IccFileHandler,读取SIM卡字段


[java] view plaincopy


1. public void loadEFTransparent(int fileid, Message onLoaded) {  

2.         Message response = obtainMessage(EVENT_GET_BINARY_SIZE_DONE,  

3.                         fileid, 0, onLoaded);  

4.   

5.         phone.mCM.iccIO(COMMAND_GET_RESPONSE, fileid, getEFPath(fileid),  

6.                         0, 0, GET_RESPONSE_EF_SIZE_BYTES, null, null, response);  

7.     }  

大家注意到phone.mCM.iccIO,这个东东就是我们的RIL.JAVA, 向低层的MODEM 发送一个读取SIM卡的命令,在RIL.JAVA 中。Fileid 是字段的地址,如上面说的AND(在这为6F3A),FDN(在这为6F3B). 

3.当低层的MODEM读到字段结果后,会有一个返回结果,由于发送读取请求时,有一个事件信息EVENT_GET_BINARY_SIZE_DONE,当有返回时,会直接交给IccFileHandler,然后由IccFileHandler转发给SIMRecords,最后进行处理该字段读完后应该执行的操作。由RIL.JAVA通知IccFileHandler,处理如下

3.                response = (Message) ar.userObj;

36.                                              fileid, 0, response));  

37.            break;  

回到SIMRecords,处理ICCID读完后相关操作,代码如下: 

[java] view plaincopy 

1. case EVENT_GET_ICCID_DONE:  

2.                 isRecordLoadResponse = true;  

3.   

4.                 ar = (AsyncResult)msg.obj;  

5.                 data = (byte[])ar.result;  

6.   

7.                 if (ar.exception != null) {  

8.                     break;  

9.                 }  

10.   

11.                 iccid = IccUtils.bcdToString(data, 0, data.length);  

12.   

13.                 Log.d(LOG_TAG, "iccid: " + iccid);  

14.   

15.             break;


 


到此,一个完整的SIM卡读取过程就完成了。


PS:有可能有人会问,为什么有时候是


iccFh.loadEFTransparent


有时候是


iccFh.loadEFLinearFixed


这主要是跟所要读取EF的类型有关系,SIM卡上的文件类型有Elementary File, Delicated File, Cyclic File,其中EF又分为Linear fixed EF,Transparent EF,Cyclic EF,所以读取的方式是不一样的,可能参考3GPP 11.11,  3GPP 51.011.


OK, 累了,有什么问题,可以在下面问,
