[b]阅先申明，本帖不是对广电的挑战，只是技术上的共同探讨。[/b]
我们先研究一下户户通的GPRS基站用处与原理：
[backcolor=#ffffff][color=#333333][font=Arial]2.2 基站定位实际工作情况[/font][/color][/backcolor]
[backcolor=#ffffff][color=#333333][font=Arial]2.2.1 用户信息的网上录入 [/font][/color][/backcolor][backcolor=#ffffff][color=#333333][font=Arial]将用户信息在用户管理系统中按要求进行录入，目的是实现用户、机顶盒与智能卡的绑定关系，保证信息的一一对应，操作成功后，该数据将储存于直播卫星管理中心用户管理系统，用户的状态显示为“等待安装”。[/font][/color][/backcolor]
[backcolor=#ffffff][color=#333333][font=Arial]
[/font][/color][/backcolor]
[backcolor=#ffffff][color=#333333][font=Arial]2.2.2设备开通时基站信息的写入[/font][/color][/backcolor][backcolor=#ffffff][color=#333333][font=Arial]根据安装开通要求，户户通设备开通地和使用地要一致，其目的是要实现开通地与用户使用地之间的关联。其实现步骤如下： [/font][/color][/backcolor][backcolor=#ffffff][color=#333333][font=Arial]1）将开通GPRS功能（信号回传采用的是数据通道）的手机卡放入户户通接收机（机顶盒）位置锁定模块中固定好，GPRS信号将开通地移动基站信息上传到直播卫星管理中心。 [/font][/color][/backcolor][backcolor=#ffffff][color=#333333][font=Arial]2）直播卫星管理中心将收到的信息与数据库内的信息进行比对，比对成功后将上传的基站信息、设备信息通过卫星下传通道写入智能卡，这时用户管理系统中的用户状态从“等待安装”变为“基站匹配”、“基站匹配*”或“正常”。[/font][/color][/backcolor]
[backcolor=#ffffff][color=#333333][font=Arial]
[/font][/color][/backcolor]
[backcolor=#ffffff][color=#333333][font=Arial]2.2.3用户使用中基站信息的比对[/font][/color][/backcolor][backcolor=#ffffff][color=#333333][font=Arial]在用户实际使用过程中，每次开机后户户通设备会自动搜索基站信息，并自动和智能卡中已储存的基站信息进行比对，只要有一组比对成功，则认为使用区域未发生移动，用户可以正常收看，否则就会认为实际使用位置发生变化，一段时间后（目前直播卫星管理中心的设置的是10天）用户将无法正常收看节目。[/font][/color][/backcolor]
[backcolor=#ffffff][color=#333333][font=Arial]
[/font][/color][/backcolor]
[backcolor=#ffffff][color=#333333][font=Arial]
[/font][/color][/backcolor]
[backcolor=#ffffff][color=#333333][font=Arial]也就是说，你在服务区定位，上传正确的基站信息，与广电数据库中白名单数据比较，合法的基站数据，就可以定位授权 。[/font][/color][/backcolor]
[backcolor=#ffffff][color=#333333][font=Arial]那么这时，你的机子所有信息在广电数据中都是正常的。[/font][/color][/backcolor]
[color=#333333][font=Arial][backcolor=#ffffff]下面如果你移到别的地方了，那么周边的基站变了，机子自己会比较，我们只要给CPU原来定位时的基站数据就行了。[/backcolor][/font][/color]
[color=#333333][font=Arial][backcolor=#ffffff]用单片机彻底解决了这个问题。[/backcolor][/font][/color]
在单片机中运行加载服务区的基站数据，断开原来GPRS与CPU的I/O接口，把单片机I/O接口接上。
当然，GPRS模块原来的数据送到CPU时，里面是加了数字签名的，这个数字签名毫无疑问比CA卡简单了一千倍。别的你懂的，不用多讲。
