[36] 图 5是本发明实施例手机的 SIM卡重启模块内部原理框图。
[37] 具体实施方式
[38] 本发明所提供的一种手机 SIM卡掉卡恢复方法及手机, 为使本发明的目的、 技 术方案及优点更加清楚、 明确, 以下参照附图并举实施例对本发明进一步详细 说明。 应当理解, 此处所描述的具体实施例仅仅用以解释本发明, 并不用于限 定本发明。
[39] 本发明实施例的一种手机 SIM卡掉卡恢复方法中, 如图 1所示, 手机主要由基 带芯片 (Baseband) 、 SIM卡及连接 SIM卡的卡座 (图 1中未标识) 等组成。
[40] 其中, SIM卡与基带的主要电气信号连接为:
[41] VSIM为 SIM卡的供电电压脚; SIM— RST为基带芯片给 SIM卡的复位信号脚, 用
. 于 SIM卡的复位。
[42] SIM— CLK: 为基带芯片给 SIM卡的时钟信号脚, 用于 SIM卡的工作时钟; SIM一
DATA: 基带芯片与 SIM卡之间的数据信号脚。
[43] 在具体实施吋, 本发明所述的手机 SIM卡掉卡恢复方法, 当 SIM卡的电气信号 出现干扰导致数据传输错误吋, 将 SIM卡的电源关掉; 并重新给 SIM卡上电, 重 新进行 SIM卡的访问与网络的-连接。
[44] 在具体实施吋, 如图 2所示, 包括以下步骤:
[45] 步骤 S2I.0、 当 SIM卡的电气信号出现干扰导致数据传输错误时, 控制关闭 SIM 卡供电电压脚的电源。
[46] 譬如, 当 SIM卡的电气信号出现干扰导致数据传输错误 (即 SIM卡掉卡) 吋, 将 SIM卡的电源关掉, 如图 1所示, 即可以控制将 SIM卡的 VSIM (供电电压) 脚 电压关闭, 即给 SIM卡下电。 由于 SIM卡的电源本身是一个 LDO (低压差线性稳 压) 输出, 可以通过软件直接 其ENABLE (启用) , DISABLE (禁用) 来打 幵和关闭 SIM卡供电。 其实现时参见如下控制参数表:
0x83010814 Driver Control and Charger Status PMIC_C0N5
Figure imgf000006_0001
[4刀 *((volatile unsigned short *) 0x83010814) &=~0xl00;关闭 VSIM。
[48] 通过上述程序语句, 可以实现对 SIM卡电源关闭。 其中 volatile是定义变量的前 缀修饰, 当要求使用 volatile声明的变量的值的时候, ***总是重新从它所在的 内存读取数据, 即使它前面的指令刚刚从该处读取过数据。 unsigned short是定义 短字的变量, 在 ARM上是 16位的两字节长。
[49] 然后再按如图 3所示的 SIM卡上电时序图, 重新给 SIM卡上电, 上电顺序如 '下:
[50] 步骤 S220、 重新给 SIM卡上电, 先给 SIM卡的供电电压脚重新加上 3V的电源, 并给 SIM卡的时钟信号脚加上频率为 3.25MHz或 3.87MHz的时钟信号。
151} 譬如, 如图 3所示, 其 VSIM1信号为给 SIM卡的供电电压脚 VSIM供电的指示信 号, 图 3中, VSIM1先给 3V, 即基带通过 SIM卡的供电电压脚 VSIM先给 SIM卡加 上 3.0V (因为 SIM卡的 VSIM是一个 LDO (低压差线性稳压) 输出, 而且是可以 配置输出电压的, 只需要通过软件将该 LDO的输出配置为 3.0V并输出。 其 VSIM 的 LDO的 ENABLE (启用) 信号是一个 LDO的输出, 使用如下程序语句打开 SIM 卡的供电电压脚 VSIM的电源, 以给 SIM卡重新上电:
[52] ^((volatile unsigned short *) 0x83010814) 1= 0x100;打开 VSIM
[53] 然后再给 SIM卡的时钟信号脚 SIM— CLK加上频率为 3.25MHz或者 3.84MHz的吋 钟信号 SIM— CLK1 , 如图 3所示 (因为吋钟信号 SIM_CLK1是基带的 SIM卡接口的 时钟输出, 输出的频率是固定的, 对于 MTK平台 (一种手机软件平台) , 其频 率为 3.25MHz , 对于 QUALCOMM平台 (一种手机软件平台) , 其频率为 3.84M Hzo 而且该时钟输出也是可以被 ENABLE (启用) ,DISABLE (禁用) 来打开和 关闭的。 ) 使用语句: * ((volatile unsigned short *) 0x810a0008) 1= 0x5d2;打开 SIM CLK 具体控制参数参照下表:
SIM +0008h SIM Baud Rate Register SIM_BRR

Scl S'[MCI,K frequency
13/2 Mllz
13/4 Mliz

I tcraiiDCS I c duradon of elcmentsiv bine unit in unit of SIMCL
[56] 其中上述表中: SIM Baud Rate Register为 SIM卡注册的波特率;
[57] Set SIMCLK frequency设置 SIM吋钟频率;
[58] ETU: 基本时间单元;
[59] Determines the duration of elementary time unit in unit of SIMCLK:确定 SIM卡时钟
. 的初级时间单元。
[60j 步骤 S230、 将 SIM卡的复位信号脚的信号拉高为高电平信号。
[61] 如图 3所示, SIM— RST1信号是加在 SIM卡复位信号脚 SIM— RST上的复位信号, 将复位信号 SIM— RST1拉高为高电平 1信号 (SIM— RST1也是基带芯片的 SIM卡接 口的一个控制信号, 可以通过软件来进行拉高和拉低, SIM卡的复位信号脚 SIM — RST只是一个 GPIO口, 可以通过写 GPIO拉高即可) 。
[62] 步骤 S240、 接收 SIM卡返回的应答复位信号, 通知基带芯片 SIM卡已重新连接 。 等到 SIM卡返回的 ATR (answer to reset) , 在如图 3所示的时序完成后, SIM 卡会自动输出数据 SIM一 DATA, 该数据为应答复位信号 ATR (answer to reset) , 用于 SIM卡告知基带芯片有 SIM卡在 SIM连接器 (卡座) 上, 并进入步骤 S250
[63] 步骤 S250、 读取 SIM卡内部的信息并控制 SIM卡重新与网络进行连接。
[64] 譬如, 通过读取 SIM卡内部的信息并重新与网络进行连接 (在应答复位信号 ( ATR) 后的关于 SIM卡的操作, 可以重新走软件***的 SIM卡启动路线, 与现有 技术做法相同。 )
[65] 由上可见, 本发明实施例的手机 SIM卡掉卡恢复方法, 其控制 SIM重起过程时 间相当短, 在 1秒钟以内 所以可以在 SIM卡掉卡的时候迅速对 SIM卡进行重启
, 并进行 SIM卡的访问与网络 连接, 与整个手机***重启相比, 有效地节约了 时间, 为用户提供了方便。
[66] 基于上述实施例的手机 SIM卡掉卡恢复方法, 本发明实施例还提供了一种手机
, 如图 4所示, 所述手机 400主要包括:
[67] SIM卡重启模块 410 , 用于当 SIM卡的电气信号出现干扰导致数据传输错误时, 将 SIM卡的电源关掉; 并重新给 SIM卡上电, 重新进行 SIM卡的访问与网络的连 接, 具体如上所述。 .
[68] 如图 5所示, 所述 SIM卡重启模块 410进一步包括:
[69] 第一控制单元 41 1 , 用于当 SIM卡的电气信号出现干扰导致数据传输错误时, 控制关闭 SIM卡供电电压脚的电源, 具体如上所述。
