Description

一种高频无线智能卡低功耗、 并行处理的实现方法 技术领域 本发明涉及高频无线智能卡，本发明旨在公开一种高频无线智能 卡低功耗、并行处理的实现方法， 高频无线智能卡可通过高频发射来 作数据传输， 使用该方法实现的高频无线智能卡， 能并行处理， 不仅 说
具有低功耗的特点， 而且同时能实现高速刷卡。移动通信终端上所使 用的智能卡（SIM卡或者 USIM卡）扩书展了这个功能后， 就能够方便 实现移动支付功能及各种基于手机的物联网应用， 并大规模推广。 背景技术 随着移动通信终端， 比如手机的应用普及。基于移动通信终端的 电子钱包， 手机门禁、手机支付等新的应用需求也越来越引起广泛兴 趣。
要满足这些应用，最好的方式是跟现有射频卡刷卡使用方式相同 或者相近。这就要求移动通信终端能够像射频卡一样可以通过无线数 据通信来跟消费终端、 或者门禁控制器来交换数据。
通过手机实现移动支付等功能， 需要在手机上实现近场通信功 能， 目前在手机上实现近场通信功能主要有四种模式， 第一种模式是 NFC 手机， 是在现有的手机上集成 NFC 通信模块 （Near Field Communication),采用的是 13.56MHz的低频感应模式，属于被动式， 需要用户更换手机；第二种模式是在手机 SIM上加装 13.56MHz的低 频感应模块， 需要改装 SIM卡， 并且在 SIM上会带很大一个感应电 路， 这种模式无法大规模商业化； 第三种模式是在手机上加装 2.4G 的有源高频感应模式， 能有效的解决穿透问题， 该种模式在日本得到 发展， 缺点是用户需要专用的手机， 这一点不适合用户更换手机的使 用习惯；第四种模式是在 SIM卡上集成 2.4G的有源高频感应模块 (一 种频率为 2.4G的高频无线智能卡， 习惯将其称为 RF-SIM卡）， 该种 模式非常符合用户的使用习惯。 ***选用了第四种模式， 并作为 移动支付的首要标准。
当移动通信终端配备了高频无线智能卡后， 比如手机用高频无线 智能卡做 SIM卡， 其基本的工作原理如下：
高频无线智能卡 107包含两部分， 即终端通信模块 101和射频通 信模块 102。 移动通信终端 105在工作中把高频无线智能卡 107当做 一个通常的智能卡 （比如 SIM卡） 来看待。 移动通信终端工作过程 中（比如手机通话时或者待机时）把高频无线智能卡 107当做一个从 通信设备，所有与高频无线智能卡 107相关的通信请求都是由移动通 信终端来发起， 高频无线智能卡 107来应答， 由终端通信模块 101来 完成 IS07816通信 103， 参见图 1。 而且， 该高频无线智能卡 107也 可与读卡器 106作射频刷卡通信 104 (比如在 POS机刷卡）， 射频刷 卡通信 104参见图 1。只要按照 IS07816的协议所要求的时序和应答 数据来完成 IS07816通信，就可以在不改变现有移动通信终端的任何 流程的情况下， 来扩展出高频无线传输的功能， 比如刷 POS。
通常的移动通信终端 （比如手机）， 其 SIM卡为了降低功耗， 一 般设计成只在与手机交换数据时工作 （IS07816通信）， 其余时间处 于的休眠状态。 所谓休眠状态， 指的是 SIM卡芯片里处理器处于停 止执行指令的状态， 此时的功耗非常低。 手机与 SIM 卡的通信 (IS07816通信）是按照 IS07816的标准来实现， 手机是数据发起的 主动方， SIM卡芯片是接收应答方， 手机每间隔一段时间对 SIM做 一次主动查询， 比如发一个 5个字节的命令包给 SIM卡， 此时 SIM 卡从休眠状态转为工作状态，回复手机若干字节，大概在 1毫秒完成， 此时如果没有其他的通信需求， 手机 SIM卡立即转为休眠状态。 通 过这种方式来降低手机功耗， 延长待机时间。 一般的手机 SIM卡不 带射频通信模块， 没有射频刷卡功能， 只有 IS07816通信， 因此只存 在 （IS07816通信） 工作和 （IS07816通信） 休眠两种状态。 当手机 使用扩展了射频刷卡功能的智能卡作为 SIM卡时， 由于增加了刷卡 功能， 即 （射频刷卡通信）， 此时， 带射频刷卡模块的 SIM卡会出现 四种工作状态：第一、 IS07816通信未工作，射频刷卡通信也未工作， 高频无线智能卡处于休眠状态； 第二、 IS07816通信工作， 射频刷卡 通信未工作； 第三、 IS07816通信未工作， 射频刷卡通信工作； 第四、 IS07816通信和射频刷卡通信同时工作。因为不同手机与手机 SIM卡 之间两次通信的间隔（手机主动查询的间隔）时间由手机所决定， 差 异很大， 比如诺基亚为 5秒， 三星为 2秒， 如果高频无线智能卡也是 只在与手机通信时， 才进入工作状态， 此时再与射频读卡器作数据交 换， 即通过手机轮询一唤醒 SIM卡 一进入刷卡状态的方式， 刷卡时 间上让用户难以忍受。 极端状况下， 手机与手机 SIM卡之间两次通 信的间隔会超过 10多秒， 这样一来 10多秒都无法完成交易流程。而 目前在公交刷卡和地铁刷卡领域， 一般刷卡时间为不超过 300ms。
为了让手机能在很短的时间内能响应刷卡，必须让高频无线智能 卡无论在什么工作状态下， 都能响应刷卡， 但是如果随时保持高频无 线智能卡的刷卡工作状态即如上所述第三、 四种工作状态， 其功耗将 是难以忍受的。 因此， 对于高频无线智能卡， 响应刷卡时间低和功耗 低始终是两个难点。 专利 200410036263.4和专利 200710124354.7并 未描述该技术难点如何解决，从***利用现有技术使用的情况来 看， 主要存在以下的缺陷：
1 ) 功耗问题： 手机供电， 需要智能卡的功耗要小；
2) 距离控制： 2.4G本来是用于一种中长距离的通讯频率， 使用 到移动支付中需要将通讯距离控制在 10厘米左右；
3 ) 机卡兼容性问题： 需要与手机具有良好的兼容性；
4) 刷卡响应时间慢。
其中 1 )、 3 )、 4) 项都是与上文所述的难点有关。 总之， 现有的 技术推出的产品不仅成本高， 而且使用效果不好， 从而影响了现有移 动商务用户的使用及商业化进程，这也是目前***推广该应用的 障碍之一。 如何实现高频无线智能卡的低功耗，有效控制瞬间电流及实现高 速刷卡， 一直是该领域的一个技术难点， 也是高频无线智能卡产业化 的一个关键技术点， 有一些专利对相关技术进行了研究。 专利
200410036263.4 描述了高频无线智能卡的硬件基本组成， 包含的要 素， 但并未阐述如何去实现低功耗及高速刷卡； 专利 200710124354.7 和专利 200410036263.4很接近， 只是更细致的阐述了高频无线智能 卡的几种物理结构及逻辑原理，没有涉及到如何实现降低功耗和确保 高速刷卡等非常重要的软件及硬件技术特征。
对于移动通信终端特别是手机来说， 低功耗是一个重要技术要 求， 否则会导致手机待机时间过短、 无法识别 SIM卡， 甚至无法开 机； 高速刷卡也是移动支付要求的一个重要指标。 因此， 解决这两个 问题是高频无线智能卡产业化的关键之一。 发明内容 针对现有技术中存在的缺陷，本发明的目的在于提供一种高频无 线智能卡低功耗、 并行处理的实现方法， 解决以上的技术难点， 这就 要求高频无线智能卡任何时候都能从如上所述第二、三、四种状态迅 速切换到第一种工作状态， 也能从第一种工作状态迅速转换到第二、 三、 四种中的任意一种状态， 即只在作 IS07816通信或（和）作射频 通信时高频无线智能卡才进入高功耗的工作状态， 工作状态完成， 迅 速转入休眠状态。

本发明所述的高频是指很容易穿透移动通信终端的 VHF频段和 UHF频段以及 SHF频段， 同时避开跟移动通信所使用的频段， 以防 冲突。
所述的并行处理， 分为两种情况：
一种是单处理器多任务并行模式， 所述的处理器是指用于处理 IS07816通信和射频刷卡通信的处理器只有一个；
另一种是多处理器多任务处理的模式，是指 IS07816通信和射频 刷卡通信分别由不同的处理器处理，两个处理器之间再通过数据接口 通信， 该通信之间不一定是实时的。 下面分别就两种情况作论述。
一、 单处理器多任务模式
对于单处理器多任务模式，所述的高频无线智能卡至少有以下两 部分组成， 包括终端通信模块， 射频通信模块。 终端通信模块主要用 于辅助移动通信终端的一般通信功能， 比如手机网络的鉴权、参数存 储等， 射频通信模块部分用于实现和读卡器的高频通信， 比如刷卡支 付、控制门禁等业务。终端通信模块可以由具备手机 IS07816接口功 能的安全芯片来实现（比如瑞士 EM公司的 TG360芯片）， 射频通信 模块包含射频芯片 （比如 NRF24L01 )、 ***电路和射频天线。 高频 无线智能卡的封装外观可以类似普通手机 SIM卡。 或者将终端通信 模块和射频通信模块，通过集成电路的技术，集成在一个芯片里实现。 射频通信模块所使用的频段不应与现有手机频率互相干扰，同时能穿 透手机机身。 高频无线智能卡首先要完成一个普通的 SIM 卡或者 USIM卡的功能， 同时能扩展高频无线传输的功能来实现基于移动通 信终端的电子钱包， 手机门禁、 手机支付等新的应用需求。
所述的终端通信模块和射频通信模块必须具备如下功能： 所述的终端通信模块由安全芯片来实现，所述的安全芯片按照现 有技术水平最少含有处理器、 随机存储器、 永久存储器， 在硬件上必 须具备 IS07816通信中断功能，并且具备时钟中断功能或者扩展了多 10、 具备 10中断功能的安全芯片。 即本发明要求的安全芯片硬件上 必须具备 IS07816通信中断和时钟中断功能， 或者具备 IS07816通 信中断和 10中断功能。现有的所有安全芯片都至少具备通过 IS07816 通信中断使芯片从休眠状态转换到工作状态的能力，本发明所要求的 安全芯片除了具备以上能力外， 还要求具备利用时钟中断或者 10中 断使芯片从休眠状态转换到工作状态的能力。安全芯片具备了上述中 断功能， 即能通过分时并行处理两个或两个以上任务， 并且具备了通 过中断使芯片从休眠状态转换到工作状态的能力，就可以使安全芯片 在平均功耗很低的情况下处理多任务 （比如瑞士 EM公司的 TG360 芯片即具备以上的硬件功能）。
本发明所述的终端通信模块的安全芯片和射频通信模块有如下 四种连接方式：
1. 图 2 IS07816通信中断和时钟中断模式。高频无线智能卡 209 上设有终端通信模块的安全芯片 201和射频通信模块 202， 终端通信 模块的安全芯片 201和射频通信模块 202的射频芯片至少各通过两组 10口形成两条连接，一组 10口是用于射频数据通信的 10口 203 (数 据通信交换端口），另一组 10口为用于射频状态检测的 10口 204 (射 频状态检测端口）， 通过电路 （射频数据通信连接电路 205和射频状 态检测连接电路 206) 分别将两颗芯片的两个端口连接起来。 此时所 有的软件工作流程， 都是由安全芯片来控制完成。终端通信模块的安 全芯片 201实现 IS07816通信 207，射频通信模块 202实现射频刷卡 通信。 所述的软件工作流程如下： （参见图 7)
首先是装有高频无线智能卡的移动通信终端开机 （比如 RF-SIM 手机开机）， 高频无线智能卡内的安全芯片复位， 通过高频无线智能 卡内的软件， 进行参数初始化， 比如手机 SIM卡 （或 USIM卡） 参 数初始化， 并通过安全芯片与射频通信模块连接的数据通信交换端 口， 对射频通信模块参数作配置， 包括通信速率、 频点、 数据包的大 小等， 给移动通信终端， 比如手机， 返回复位信息， 设置安全芯片， 允许它在 IS07816中断或时钟中断时，从休眠状态进入工作状态。移 动通信终端， 比如手机， 进入休眠状态， 此时 IS07816通信未工作， 射频刷卡通信未工作， 移动通信终端处于最省电状态。 此时， 因为某 种中断被唤醒，判断是哪种中断？ 如果是 IS07816中断，处理 IS07816 通信事务， 处理完成， 进入休眠状态； 如果是时钟中断， 通过检测射 频通信模块射频状态检测端口的电平高低状态来判断射频通信模块 是否收到读卡器的数据， 如果收到数据， 处理射频刷卡通信事务， 处 理完成， 结束中断， 进入休眠状态； 如果没有收到数据， 结束中断， 进入休眠状态。由于射频刷卡任务和 IS07816通信事务占用的时间都 不多， 一般都在毫秒数量级， 安全芯片可通过分时执行来处理， 移动 通信终端或者读卡器都不会察觉到高频无线智能卡在与自己通信时 也在执行另一个任务。 因此， 因时钟中断唤醒处理射频刷卡通信时， 也能并行处理 IS07816通信事务； 同样， 因 IS07816中断唤醒处理 通信事务时， 也能并行处理射频刷卡通信事务。这样， 无论高频无线 智能卡在哪种工作状态，都能迅速从高功耗的工作状态进入低功耗的 休眠状态，而且 IS07816通信和射频刷卡通信既能各自单独处理， 也 能并行处理， 这就在技术上保证既能做到高频无线智能卡的低功耗， 又能实现高速刷卡， 而且刷卡和通信能并行处理。
2. 图 3 IS07816中断和 10中断模式。 高频无线智能卡 310中， 终端通信模块的安全芯片 301和射频通信模块 302的射频芯片至少各 通过两组 10口形成两条连接， 一组 10口是用于射频数据通信的 10 口 303 (数据通信交换端口）， 通过射频数据通信连接电路 306连接， 用作安全芯片和射频通信模块的数据通信； 另一组 10口对于安全芯 片来说， 必须是安全芯片 10中断端口 304， 对射频通信模块来说， 是射频芯片的射频状态输出端口 （射频芯片射频状态检测端口 305 )， 通过射频状态检测连接电路 307将两颗芯片的两个端口（安全芯片 10 中断端口 304和射频芯片射频状态检测端口 305 )连接起来。 用于对 射频通信模块的射频状态检测。此时所有的软件工作流程， 都是由安 全芯片来控制完成。 图 3中 308为 IS07816通信， 309为射频刷卡通 信。
所述的软件工作流程如下： （图 8)
首先是装有高频无线智能卡的移动通信终端开机 （比如 RF-SIM 手机开机）， 高频无线智能卡内的安全芯片复位， 通过高频无线智能 卡内的软件， 进行参数初始化， 比如手机 SIM卡 （或 USIM卡） 参 数初始化， 并通过安全芯片与射频通信模块连接的数据通信交换端 口， 对射频通信模块参数作配置， 给移动通信终端， 比如手机， 返回 复位信息， 设置安全芯片， 允许它在 IS07816中断或 10中断时， 从 休眠状态进入工作状态。 移动通信终端， 比如手机， 进入休眠状态， 此时 IS07816通信未工作，射频刷卡通信也未工作，移动通信终端处 于最省电状态。 此时， 因为某种中断被唤醒， 判断是哪种中断？ 如果 是 IS07816中断， 处理 IS07816通信事务， 处理完成， 进入休眠状 态； 如果是 10中断， 处理射频刷卡通信事务， 处理完成， 结束中断， 进入休眠状态。由于射频刷卡任务和 IS07816通信事务占用的时间都 不多， 一般在毫秒数量级， 安全芯片可通过分时执行来处理， 移动通 信终端或者读卡器都不会察觉到高频无线智能卡在与自己通信时也 在执行另一个任务。 因此， 因 10中断唤醒处理射频刷卡通信时， 也 能并行处理 IS07816通信事务； 同样， 因 IS07816中断唤醒处理通 信事务时， 也能并行处理处理射频刷卡通信事务。 这样， 无论高频无 线智能卡在哪种工作状态，都能迅速从高功耗的工作状态进入低功耗 的休眠状态， 而且 IS07816通信和射频刷卡通信既能各自单独处理， 也能并行处理， 这就在技术上保证既能做到高频无线智能卡的低功 耗， 又能实现高速刷卡， 而且刷卡和移动通信能并行处理。

508为射频刷卡通信， 509为 IS07816通信。
以上是单处理器多任务的模式。以下论述多处理器多任务的处理 模式。
二、 多处理器多任务的模式
对于多处理器多任务的模式， 终端通信模块可以采用普通 IS07816智能卡安全芯片， 射频通信模块包括处理器、 射频芯片、 外 围电路、 天线等。 有如下二种模式
1. 图 6在高频无线智能卡 606 中， 终端通信模块采用普通的 IS07816智能卡安全芯片， 即终端通信模块的安全芯片 601， 终端通 信模块的安全芯片 601与射频通信模块 602之间通过芯片之间的数据 通信接口 603交换数据。射频通信模块可以采用如上所述图 2、 图 3、 图 4、 图 5的结构和技术， 通过处理器的时钟中断或 10中断实现射 频通信模块从休眠状态到工作状态的切换来处理射频刷卡任务；而终 端通信模块通过 IS07816 中断实现从休眠状态到工作状态的切换来 处理 IS07816通信任务。其初始化工作流程同上，只是采用两个处理 器来实现了并行处理，保证了 IS07816通信 604和射频刷卡通信 605 能各自独立工作， 并行处理， 然后再交换数据。 比如， 射频通信模块 选择目前应用很普及的一款 NRF24LE1 芯片， 该芯片包含处理器和 射频芯片， 同时具备处理器和射频接口的功能。 而且 NRF24LE1 芯 片的处理器可以通过时钟中断实现射频通信模块从休眠状态到工作 状态的切换。在工作状态时， 等待读卡器发来数据。 如果在某个时间 段内， 比如 10毫秒或 20毫秒内没有收到数据， 重新进入休眠状态。 而一旦收到数据， 则处理射频刷卡任务， 任务处理完毕重新进入休眠 状态。为了能让终端通信模块得到射频刷卡的结果， 可以在通过终端 通信模块的 IS07816 安全芯片和射频刷卡模块之间的数据通信接口 交换数据后再进入休眠状态。两个模块之间无需实时交换数据，这样， IS07816芯片平常处于未工作状态，只需在处理 IS07816通信流程时 才进入工作状态， 此时就可跟射频通信模块交换数据了， 如果射频通 信模块此时处于未工作状态，则安全芯片等待射频通信模块进入工作 状态， 再交换数据， 射频通信模块工作状态和未工作状态的切换时间 一般在毫秒数量级。 终端通信模块的处理流程如实施例 3.1流程图 9 所示， 射频通信模块的处理流程如实施例 3.2流程图 10所示。 这样， 无论是终端通信模块， 还是射频刷卡模块， 都可以迅速从高功耗的工 作状态， 迅速进入低功耗的休眠状态， 而且， 可以在确保平均功耗很 低的情况下， IS07816通信和射频刷卡能并行处理。
2. 对于图 6， 还有一种工作方式是： 通过 IS07816中断实现终 端通信模块从未工作模式到工作模式的切换，而射频通信模块部分的 处理器随时处于工作模式，但通过降低自身的运行速度来大大降低处 理器部分的功耗。 通过两个处理器来实现并行处理， 实现 IS07816 通信和射频刷卡通信同时进行。这种模式下， 终端通信模块的平均功 耗仍然很低，射频通信模块部分的功耗比以上所述的模式功耗要高一 些， 但总体功耗仍处于较低水平。
总体来说， 按照本发明一系列的技术方法， 可以实现一种低功耗 高刷卡速度的高频无线智能卡。最终使得高频无线智能卡从概念转变 成一种真正可使用的产品。
