Description

一种智能卡非接触通信技术的选择方法及系统 技术领域
本发明涉及非接触通信技术领域, 具体涉及一种智能卡非接触通信技术 的选择方法及系统。
随着科技的日益进步, 智能移动终端如手机的功能已经不仅仅局限于打 电话和发短信等简单的基本通信功能,它现在已经成为人们便携的娱乐设备, 同时它在消费、 交通等领域能方便快捷的完成非接通信, 基于手机的非接触 通信技术业务(如移动支付业务) 已经进入了人们的生活。 非接触通信技术 业务逐渐成为移动运营商、 手机制造商、 SIM 卡制造商等研究的热点问题。 目前主流的非接触通信技术方案有两种: 一种是 SIMpass技术方案, 一种是 SWP技术方案。 为此, 相关的支持 SIMpass技术的智能卡和支持 SWP技术的 智能卡也应运而生。
SIMpass 技术方案要求智能卡外接天线或者把天线集成到智能卡里, 智 能卡直接通过天线和外部终端设备通信。 支持 SIMpass技术的智能卡也被称 之为双界面 SIM卡, 它同时支持接触和非接触两种工作模式, 接触界面实现 SIM功能, 非接触界面实现非接触通信功能。 利用 SIMpass技术, 可在无线 通信网络及相应的平台的支持下,开展各种基于手机的现场非接触通信服务。 典型的非接触通信技术业务应用场景是北京一卡通公交, 用户只需拿着支持 SIMpass技术的智能卡在公交 P0S机前轻松一挥即可安全、便捷的完成支付。 支持 SIMpass技术的智能卡仅限在相应的手机上使用, 即只支持 SIMpass技 术的智能卡一般情况下只能在普通手机(非 SWP手机) 上正常工作, 在大多 数 SWP手机上无法正常工作。 其原因在于支持 SWP的手机具有与外部终端设 备通信的功能, 而支持 SIMpass技术的智能卡也具有与外部终端设备通信的 功能, 这样就会导致装有 SIMpass技术的智能卡的 SWP手机与外部终端设备 通信发生混乱、 或者信号强度衰减, 导致无法正常通信。
SWP技术方案要求智能卡支持 SWP协议, 手机通过 NFC芯片与外部终端 设备通信, 然后手机把通信数据转换成符合 SWP协议格式的数据包, 然后再 与智能卡通信。 手机的 NFC芯片与 S IM卡的 C6触点相连实现数据通信。 SWP 技术是一种在单线上实现全双工通信的技术, 通信双方通过电压信号和电流 信号叠加在一起, 在一条单线上实现全双工通信。 只支持 SWP技术的智能卡 仅限在相应的手机上使用非接功能, 即只支持 SWP技术的智能卡只能在 SWP 手机上正常的进行非接通信, 在普通手机上无法正常的进行非接通信。 其原 因在于支持 SWP的手机具有 NFC 芯片, 可与外部终端设备通信, 并会把通信 数据转换成符合 SWP协议格式的数据包与支持 SW协议的智能卡通信。 而普 通手机上却不具有 NFC芯片, 不能与外部终端设备进行通信, 这样就无法获 取通信数据。 同时普通手机也不具有 SWP功能, 无法把通信数据转换成符合 SWP协议格式的数据包并与支持 SWP协议的智能卡通信。 发明内容

本具体实施方式中的通信技术选择模块 11 包括主动选择与屏蔽单元和 被动选择与屏蔽单元, 其中,
主动选择与屏蔽单元用于智能卡根据其所接收到的通信信号来源自动选 择其所支持的非接触通信技术: 若智能卡接收到的是来自 SWP信道的信号, 则屏蔽智能卡的 SIMpass技术, 若智能卡接收到的是来自 SIMpass信道的信 号, 则屏蔽智能卡的单线协议 SWP技术。
被动选择与屏蔽单元用于确定智能卡接收到的通信信号来源, 并查看信 号来源与用户预设的智能卡所支持的非接触通信技术是否相对应, 若是则选 择智能卡支持的非接触通信技术为用户预设的智能卡所支持的非接触通信技 术, 若否则通信结束。
也就是说, 通信技术选择模块 11 选择智能卡所支持的非接触通信技术 时, 支持主动选择与屏蔽模式和被动选择与屏蔽模式。 主动模式下智能卡根 据接收的信号来源自动选择与信号对应的技术, 屏蔽不支持技术; 被动模式 下根据用户预设的移动智能终端支持的技术, 屏蔽不支持的技术, 在被动模 式下, 如果用户预设的技术与智能卡接收到的信号不对应, 则该模式下就会 出现通信失败的情况。 图 2中示出了通过本具体实施方式中基于移动终端类型的非接触通信技 术的选择系统的智能卡识别移动智能终端所支持的非接触通信技术的框图, 智能卡芯片的主要功能是给智能卡 COS (智能卡卡片操作系统)提供硬件支 持, SIMpass模块的主要功能是负责 SIMpass非接触通信技术相应的通信处 理, SWP模块的主要功能是负责 SWP非接触通信技术相应的通信处理。 当智 能卡和外部终端设备进行通信时,智能卡 10将其所接收到的信号来源发送的 选择与屏蔽模块, 并根据屏蔽模式确定其所支持的非接触通信技术 SWP技术 或是 SIMpass技术。 其中, 用户设置模块的主要功能是通过智能卡 COS给用 户提供 STK菜单来设置屏蔽模式,包括上述的主动屏蔽模式和被动屏蔽模式, 选择与屏蔽单元是根据用户设置模块设置的屏蔽模式来确定智能卡选择其所 支持的非接触通信技术的方式为主动选择还是根据用户预设的技术进行选 择。 图 3示出了本发明具体实施方式中一种智能卡非接触通信技术的选择方 法的流程图, 该方法包括以下步骤:
步骤 S21: 将智能卡装载到移动智能终端中;
步骤 S22: 智能卡根据接收到的通信信号来源选择其支持的非接触通信 技术;
本具体实施方式的智能卡支持 SIMpass技术和单线协议 SWP技术, 在实 现方式上可以通过在智能卡上集成双界面智能卡芯片使其支持 SIMpass 技 术, 通过在智能卡上集成 SWP智能卡芯片支持 SWP技术, 即本具体实施方式 中的智能卡芯片是指集 SWP芯片和 SIMpass芯片于一体的智能卡芯片, 这个 芯片既要能进行 SWP通信又要可以进行 SIMpass通信。
在将智能卡设置到移动智能终端后, 移动智能终端与外部终端设备(如 银行的 P0S机、 公交刷卡机等) 进行非接触通信时, 智能卡根据接收到的通 信信号来源选择其支持的非接触通信技术, 本具体实施方式中智能卡接收到 的信号来源分为两大类, 一类是来自 SWP信道的信号, 另一类来自 SIMpass 信道的信号。
本具体实施方式中智能卡根据其接收到的信号来源选择其所支持的非接 触通信技术的一种方式为:

确定智能卡接收到的信号来源, 并查看信号来源与用户预设的智能卡所 支持的非接触通信技术是否相对应, 若是则选择智能卡支持的非接触通信技 术为用户预设的智能卡所支持的非接触通信技术, 若否则通信结束。 即根据 用户预设的智能卡所支持的非接触通信技术确定智能卡支持的非接触通信技 术。 其中, 用户可以通过用户识别应用发展工具 STK菜单预设智能卡所支持 的非接触通信技术。 在实际应用过程中, 在选择了智能卡所支持的非接触通信技术后, 智能 卡即可根据选择的非接触通信技术与外部终端设备进行通信, 从而完成非接 触通信业务, 即图 3中所示的步骤 S2 3, 如果智能卡釆用 S IMpa s s技术, 智 能卡直接通过其外界天线或者集成到智能卡里的天线与外部终端设备通信, 完成非接触通信业务; 如果智能卡釆用 SWP技术, 移动智能终端通过 NFC芯 片与外部终端设备通信, 然后智能移动终端再把通信数据转换成符合 SWP协 议格式的数据包, 再与智能卡通信, 从而完成非接触通信业务。
另外, 需要说明的是, 本具体实施方式中的移动智能终端包括但并不限 于智能手机。 本发明所述的方法及系统中, 当智能卡与移动智能终端置于有足够场强 的非接场中, 智能卡中的天线就会由感应, 并进行非接通信, 接收通信信号。 在主动屏蔽模式下智能卡收到 SWP通道传来的信号时,自动切换到 SWP通道, 同时屏蔽 S IMpa s s通道; 当卡片收到 S IMpa s s通道传来的信号时, 自动切换 到 S IMpa s s通道, 同时屏蔽 SWP通道; 当两个通道都没有信号时, 两个通道 都处于开启状态。 在被动屏蔽模式下, 根据用户预设的智能卡所要支持的非 接触通信技术, 屏蔽掉手机不支持非接触通信技术。 通过本发明的方法及系 统, 智能卡可以自动识别出当前应该使用哪种类型的天线的技术, 并根据选 择的结果选择智能卡要支持的非接触通信技术, 然后完成非接触通信业务, 满足用户的通信需求。 发明的精神和范围。 这样, 倘若本发明的这些修改和变型属于本发明权利要 求及其同等技术的范围之内, 则本发明也意图包含这些改动和变型在内。
