Description

终端及其的切换方法
技术领域 本发明涉及通信领域， 具体而言， 涉及一种终端及其的切换方法。 背景技术 近距离无线通信 （Near Field Communication, 简称为 NFC) 是一种短距离的非接 触式通信技术， 通过频谱中无线频率部分的电磁感应耦合方式传递信息。 NFC技术具 有数据传输更安全、 反应时间更迅速的优点， 目前已经广泛用于小额支付、 身份认证 等领域。 无线充电技术目前有 Qi标准的以电磁感应耦合方式、 无线电波方式以及 MIT提 出的电磁共振两种。 Qi标准的电磁感应耦合方式技术比较成熟，无线充电联盟 (Wireless Power Consortium, 简称为 WPC) 采用这种标准并在各行业中推动无线充电的应用。 无线电波充电方式是利用周围各种无线电波转化成电能， 该方式采用微型高效接收电 路， 可以捕捉到从墙壁弹回的无线电波能量， 在随负载做出调整的同时保持稳定的直 流电压。 此种技术比较成熟， 但是并没有得到推广。 电磁共振技术是 MIT (麻省理工 大学） 研究并命名为 witricity的无线充电技术， 且 Witricity也作为一个公司独立出来 旨在推广该技术在无线充电领域的应用。 Witricity具有较高的充电效率， 且较之前两 种技术存在的辐射性则该技术更加安全环保， 但是因为还不成熟， 所以市面上采用此 项技术的产品也较少。 目前市面上的消费电子产品琳琅满目， 种类丰富， 已经成为消费者生活中不可或 缺的一部分。 越来越多的产品将易用性作为产品竞争性的重要考量标准。 NFC用于小 额支付、 身份认证等已经较为广泛应用， 尤其是运营商的大力推广， 市面上已经有很 多产品支持 NFC。无线充电技术应用于消费电子则源于越来越智能的电子产品消耗的 电能更高更快， 如果能摆脱对充电线缆的依赖， 能实现随走随充， 将会为消费者带来 更便利的生活。 比如， 在一些公共场所设置一些无线充电源， 用户将支持统一标准的 终端设备放置在上面就可以充电， 甚至还可以一边充电一边使用设备， 充完就可以离 开， 完全不受电缆与插座数量的限制。 按照目前几种无线充电发展的状况来看，无线充电联盟推行的 Qi标准的电磁感应 方案无论在成熟性， 还是在成本、 技术支持方面都更胜一筹。 今后的消费电子终端产 品， 如果 NFC和 Qi标准的无线充电功能同时作为标配， 那么 NFC和无线充电线圈是 否干扰等工作时的共存性则是迫切需要考虑并解决的问题。
NFC的工作频率是 13.56MHz， 而无线充电工作于 ΙΟΟΚΗζ, 从现有的技术来看， 工作频率以及阻抗控制等因素决定两者天线线圈的匝数和线宽都不同， NFC与无线充 电不可能公用一个线圈。 那么两个线圈如果同时工作， 势必会存在互相影响。 针对相关技术中上述至少之一的问题， 目前尚未提出有效的解决方案。 发明内容 本发明提供了一种终端及其的切换方法， 以至少解决相关技术中缺乏一种同时具 备
