Abstract

本发明公开了一种便携终端的SIM卡安装及其分离方法,包括如下步骤:第1步骤,在终端中安装SIM卡时,通过通用输入输出接口的特定针脚接收到的高或低电平信号识别安装情况,执行基于全球移动通信系统规格的初始化程序,并在网络上允许使用后,终端转换成可使用的模式;第2步骤,在菜单上选择“分离SIM卡”项目并输入有SIM卡的针脚代码时,把终端的状态转换成识别SIM卡之前的状态,同时解除SIM卡的物理锁定,从而在便携终端上实现SIM卡的分离,物理锁定并分离是利用在便携终端内部的驱动器驱动而解除的。本发明可在装有电池的状态下安装或分离SIM卡,并通过利用PIN码的物理锁定加密操作,防止SIM卡的恶意拔除。

Description

便携终端的SIM卡安装及其分离方法
技术领域
本发明涉及移动通讯终端上安装或分离SIM(Subscriber IdentificationModule,用户识别模块)卡的技术,尤其是涉及一种在安装有电池的状态下能够安装或分离SIM卡,并同时防止SIM卡任意分离的手机的SIM卡安装及其分离方法。
背景技术
一般来说,SIM卡作为执行终端和网络之间接口功能的GSM(global systemfor mobile communication-全球移动通信系统)固有的卡,装有电话号码等针对用户的各种信息。用户在终端上安装SIM卡后开机时,将SIM卡的所有信息与网络相互传送,当允许使用上述SIM卡后就可使用终端。
在现有技术中的终端,当安装或分离SIM卡时,必须先从终端分离电池,因此电池电源将被关闭。而且,任何人都可任意从终端上解除SIM卡。
在上述现有技术终端的SIM(Subscriber Identification Module)卡的安装及其分离方法中,当安装或分离SIM卡时,必须从终端上分离电池,因此必须切断电池电源。此外,由于任何人都可任意从终端上拔出SIM卡,从而具有丢失的危险。
发明内容
本发明所要解决的技术问题在于,提供一种移动通讯终端上安装或分离SIM卡的技术,同时制作SIM卡的输入部分与PCMCIA卡的输入部,使在装有电池的状态下能够安装或分离SIM卡,并通过利用PIN码的加密操作,防止其任意分离上述SIM卡。
而且,本发明的便携终端的SIM卡安装及其分离方法,其包括如下几个步骤:第1步骤,在终端中安装SIM卡时,通过GPIO的特定针脚接收到的高或低电平信号识别上述安装情况,并执行基于GSM规格的初始化程序;第2步骤,将SIM卡信息传送给网络,当允许使用上述SIM卡时,终端转换成可使用的模式;第3步骤,在菜单上选择“分离SIM卡”项目并输入有SIM卡的PIN码时,把终端的状态转换成识别SIM卡之前的状态,同时解除SIM卡的物理锁定,从而在便携终端上实现SIM卡的分离,所述物理锁定并分离是利用在所述便携终端内部的驱动器驱动而解除的。
本发明通过同时制作SIM卡的输入部分与PCMCIA卡的输入部,使在装有电池的状态下能够安装或分离SIM卡,并通过利用PIN码的加密操作,防止其任意分离而丢失上述SIM卡。
附图说明
图1为本发明的一手机的SIM卡安装及分离方法的信号流程图。
具体实施方式
下面结合附图1对本发明的安装及其分离处理步骤进行详细说明。
首先,本发明将终端的SIM卡输入部分制作成与PC的PCMCIA(PersonalComputer Memory Card International Association,个人计算机存储卡国际协会)卡、笔记本电脑的网卡或USB卡的输入部分相同的形态。
因此,在终端上未分离电池的状态下,也能够安装或分离SIM卡。
当用户在终端上安装SIM卡时,上述终端通过GPIO(General PurposeInput Output,通用输入输出接口)的特定针脚识别上述安装情况,并执行基于GSM规格的初始化程序(步骤S1,步骤S2)。
为此,通过检测传感器对上述SIM卡的安装或分离操作进行检测,从而能够向上述GPIO的特定针脚提供“高”或“低”的信号。
这时,终端与网络相互传送上述SIM卡上的所有信息,当允许使用上述SIM卡时,终端转换成可使用的模式并开始使用(步骤S3,步骤S4)。
另外,用户为了从上述终端上分离SIM卡,在菜单上选择“分离SIM卡”项目并输入SIM卡的PIN码(PIN CODE)时,终端将自身的状态转换成识别SIM卡之前的状态,同时解除SIM卡的物理锁定状态并从上述终端分离(步骤S5-步骤S8)。
作为参考,解除上述SIM卡的物理锁定状态并从终端分离的动作,可通过在终端内部的驱动器解除锁定状态并从支持台推开的方式容易实现。
由此,用户在终端上分离SIM卡时,无需切断电池电源也可方便分离SIM卡。
如上所述,在本发明中,同时制作SIM卡的输入部分与PCMCIA卡的输入部,使在装有电池的状态下能够安装或分离SIM卡,并通过利用PIN码的加密操作,防止其任意分离而丢失上述SIM卡。
当然,本发明还可有其它多种实施例,在不背离本发明精神及其实质的情况下,熟悉本领域的技术人员当可根据本发明作出各种相应的改变和变形,但这些相应的改变和变形都应属于本发明所附的权利要求的保护范围。
