Description

通信方法及通信系统 技术领域
本发明涉及通信领域，尤其涉及一种通信方法及通信系统。
 背景技术
随着移动终端和GPS(Global Positioning System, 全球通信系统)技术的普及，越来越多的用户可以使用安装有GPS的移动终端进行定位，尤其是安装有GPS模块的手机、平板电脑等。普通用户携带此类移动终端，在相对空旷的环境通过与GPS卫星的通讯实现定位。常见的定位方式有基于移动网络、GPS、A-GPS（辅助GPS）等三种方式。基于移动网络需要移动终端能够接入GSM(Global System of Mobile communication, 全球移动通讯系统)等无线通讯网络，利用所连接的小区基站所在的位置大致对应手机所在的位置，因此这种方法的定位精度取决于移动终端所处小区基站覆盖半径的大小，从几百米到几十公里不等。基于GPS的定位技术是移动终端接收全球24颗GPS卫星的定位信号，利用其中3至4颗卫星传递的参数实现移动终端的定位。基于A-GPS的定位技术本质与GPS定位技术一样，只是将搜索卫星的步骤通过利用移动网络向位置服务平台发送所连接的小区基站信息，由位置服务平台向移动终端传递小区基站所使用的GPS卫星信息，免去移动终端搜索卫星的繁重步骤。
一般而言，基于上述原理的定位技术，实现对移动终端定位需要基于以下几个条件：
一是，基于移动网络的定位技术需要移动终端连接到GSM等移动网络；
二是，基于GPS、A-GPS的定位技术需要移动终端配备GPS模块；
三是，基于GPS、A-GPS的定位技术需要移动终端处在相对空旷的室外或者周围没有高耸建筑物的区域内。
虽然GPS定位技术为人们交通出行带来了巨大的方便，但是现实生活中仍然有很多小范围定位的应用场景无法使用GPS技术解决。这类需求并不要求实现全球范围的定位，只需控制定位精度在较小范围内（例如50米以内）的室内及地下等场合，例如地下停车场找车、大型商场店铺导购、游乐场/企业园区参观指引等。由于上述3个条件的限制，在移动网络信号、GPS信号均无法覆盖的城市大型建筑物内、地下停车场等地无法进行定位。即使GPS信号可以覆盖，很多使用旧式手机的用户由于没有配备GPS定位模块无法享受到GPS定位服务。

 本发明的最佳实施方式
本发明的实施方式
为了更好的理解本发明， 以下结合附图对本发明进行进一步说明，所举实例只用于解释本发明，并非用于限定本发明的范围。
实施例一：
本实施例中的第一通信终端可以是设置于城市大型建筑物内（例如商场内）的具备射频通信功能的支付终端或信息查询终端等，也可是设置于地下停车场等地方的支付终端或信息查询终端等；还可以是设置于公交车上的刷卡终端，本实施例中仅以以上几种情况为例进行示例性的说明。本实施例中利用射频技术实现与相应第一通信终端的目标信息的推送的过程请参见图1所示：
步骤101：设置各安装好的第一通信终端的标识信息，并将设置好的标识信息存储在第一通信终端内；本实施例中第一通信终端的标识信息可根据实际情况进行选择和设置，例如，其可以是终端厂商出厂时为其设置的具有唯一性的各种编号等，也可是另外根据一定的规则对各第一通信终端进行唯一编号的标识信息；其设置方式可根据实际情况进行选择，在此不再对其进行一一详述；
步骤102：根据各第一通信终端的标识信息设置与各第一通信终端对应的目标信息得到第一通信终端标识信息与目标信息索引表，并可将得到的第一通信终端标识信息与目标信息索引表存储到后台服务器上；此处主要是考虑到各第一通信终端的存储容量、管理成本以及传输速率等因素；当然，本发明也并不排除将第一通信终端标识信息与目标信息索引表存储到各第一通信终端上，或将各第一通信终端对应的目标信息单独存储在各第一通信终端上，这样的设置方式在动态更新各第一通信终端的目标信息时，则会提高管理等成本；因此，本实施例中以存储在后台服务器进行说明；
步骤103：检测到第二通信终端和相应的第一通信终端通过射频通道通信而激发目标信息获取流程后，根据被激发的第一通信终端的标识信息和后台服务器所存储的第一通信终端标识信息与目标信息索引表，获取到与该标识信息（也即被激发的第一通信终端）对应的目标信息；值得注意的是，本实施例中第二通信终端和第一通信终端通过射频通道通信激发目标信息获取流程的方式可以是第二通信终端与第一通信终端之间只要有射频数据交互，即可设定为激发了目标信息获取流程，而二者之间最先交互的射频数据则认为是激发目标信息获取流程指令，该指令则一般是第二通信终端下发；还可以预先设置好一定格式和内容的激发目标信息获取流程指令，第二通信终端和第一通信终端之间只有通过射频通信交互设置好的激发目标信息获取流程指令时，才判断为激发目标信息获取流程；本实施例中，与第二通信终端200进行射频交互的第一通信终端100则是被激发第一通信终端100。
可见，当本实施例中的对应于各第一通信终端设置的目标信息包括各第一通信终端当前所处的位置信息时，即可实现与第一通信终端进行射频交互的第二通信终端的精确定位，同时，该定位过程则无需在现有第二通信终端上加装GPS定位模块，即使在网络信号、GPS信号覆盖不佳的城市大型建筑物内、地下停车场等地也可以进行小范围定位，满足地下停车场找车、室内大型商场店铺导购、室外大型游乐场及企业参观等应用需求。当然，本实施例中的目标信息除了可包括位置信息外，还可包括各第一通信终端附近各商场或商家所发布的优惠信息、和/或商场、商家导航信息等惠民信息。在获取上述目标信息后，用户还可基于当前所持的第二通信终端的标识信息对获取的目标信息进行一步的筛选，以获取获取用户最感兴趣或对用户最有作用的最终目标信息。
为了更好的理解本发明，下面以实现上述过程的两种通信系统为例对本发明做进一步的说明。
图2为本发明实施例中通信系统的一种结构图。如图2所示，本实施例中，通信系统包括第一通信终端100、第二通信终端200和后台服务器300。其中，第一通信终端100和第二通信终端200之间可通过射频通道进行通信，第一通信终端100可通过网络与后台服务器300通信，具体可通过有线网络或无线网络与后台服务器300进行通信。此时，则可不要求第二通信终端200具备其他的远程通讯能力，其只需要能与第一通信终端100之间实现射频交互并能显示从第一通信终端获取的目标信息即可。在图2所示的通信系统中，根据第一通信终端100的标识信息以及存储在后台服务器上的第一通信终端标识信息与目标信息索引表匹配与该标识信息对应的目标信息的过程既可在第一通信终端100上实现，也可在后台服务器300上实现，具体如下：
图3为图2所示通信系统的一种具体结构图。图3所示实施例中，第一通信终端100包括第一主控模块110、第一射频通信模块120、第一网络通信模块130和第一存储模块140。第二通信终端200包括第二主控模块210和第二射频通信模块220。后台服务器300包括第三主控模块310、第三网络通信模块330和第三存储模块340。
其中，第一通信终端100的射频通信范围（也即可广播的范围）视定位精度而定，可以在几米至几十米范围内可调。第一通信终端100可以固定安装在人群经常经过的地方，等间距排列分布。以地下停车场为例，可以每6个车位共用一个第一通信终端100，读卡终,100安装在中间车位的上梁处，定位范围可调整至以安装位置为中心的15米半径区域内，完整覆盖6个车位。
本实施例中，第二射频通信模块220可以是置于第二通信终端中的RFID-SIM卡或RFID-SD卡；第一网络通信模块130可以通过3G、GPRS、WIFI等方式接入网络，与后台服务器300连接；第二通信终端可以是手机、个人数字助理PDA及平板电脑等。

上述过程中，在后台服务器300上根据第一通信终端100的标识信息匹配出了与第一通信终端100对应的目标信息；但在本实施例中，第二通信终端200的第二射频通信模块220还可将第二通信终端200的标识信息发送给第一通信终端100；第一通信终端100的第一网络通信模块130还可将第一射频通信模块120收到的第二通信终端200的标识信息发送给后台服务器300；后台服务器的第三主控模块310则可在匹配出上述目标信息后，根据第二通信终端200的标识信息对该目标信息进行进一步的筛选，得到更有针对性的最终目标信息。该过程可进一步为用户筛选其感兴趣的信息，提高用户体验的满意度。

后台服务器300中，第三存储模块340，用于存储第一通信终端标识信息与目标信息索引表；第三网络通信模块330用于通过网络向第一通信终端100发送第三存储模块340所存储的第一通信终端标识信息与目标信息索引表；第三主控模块310用于控制第三存储模块340和第三网络通信模块330。
上述过程中，在第一通信终端100上根据第一通信终端100的标识信息匹配出了与第一通信终端100对应的目标信息；但在本实施例中，第二通信终端200的第二射频通信模块220还可将第二通信终端200的标识信息发送给第一通信终端100；第一通信终端100的第一主控模块110则可在匹配出上述目标信息后，根据第二通信终端200的标识信息对该目标信息进行进一步的筛选，得到更有针对性的最终目标信息。该过程可进一步为用户筛选其感兴趣的信息，提高用户体验的满意度。
图2所示的通信系统是通过第一通信终端100与后台服务器进行网络连接实现相应信息的交互。但是，现有的第二通信终端200一般都既可实现近距离通讯，又具备远距离通讯能力，且在很多场景下，第一通信终端100并不具备连网条件，而难以进行推广应用。例如，当第一通信终端100为公交车上的POS机时，其要实现与后台服务器连网则比较困难。同时，通过第一通信终端100与第二通信终端200之间通过射频通信交互数据时，其推送的信息量也有限，难以推送数据量较大的图片、音频、视频等信息。因此，本实施例中还提出了另外一种通信系统，如图4所示：该通信系统包括第一通信终端100、第二通信终端200和后台服务器300。其中，第一通信终端100和第二通信终端200之间通过射频通道进行通信，第二通信终端200通过网络与后台服务器300通信,具体可通过有线网络或无线网络进行通信；即本实施例中还可利用第二通信终端200自身具备的远距离通信功能实现与后台服务器300之间的信息交互，布局、实现更简单，且其成本更低。同时，第二通信终端200与后台服务器300通过网络进行信息交互，可以通过短信、彩信或者互联网的方式进行信息交互，可以增加信息的推送量，同时还可以实现文本、图片、音频以及视频等多种类型的信息推送。
在图4所示的通信系统中，根据第一通信终端100的标识信息以及存储在后台服务器上的第一通信终端标识信息与目标信息索引表匹配与该标识信息对应的目标信息的过程也既可在第二通信终端200上实现，也可在后台服务器300上实现，具体如下：
图5为图4所示通信系统的一种具体结构图。图5所示实施例中，第一通信终端100包括第一主控模块110、第一射频通信模块120和第一存储模块140。第二通信终端200包括第二主控模块210、第二射频通信模块220和第二网络通信模块230。后台服务器300包括第三主控模块310、第三网络通信模块330和第三存储模块340。其中，第二射频通信模块220可以是置于第二通信终端中的RFID-SIM卡或RFID-SD卡；第二网络通信模块230可以通过3G、GPRS、WIFI等方式接入网络，与后台服务器300连接；第二通信终端可以是手机、个人数字助理PDA及平板电脑等。

上述获取方式三和获取方式四可以由图4、图5所示的通信系统来实施。
上述四种获取方式是以目标信息为第一通信终端的位置信息为例进行说明。在本实施例中，目标信息还可以包括各种惠民信息，例如商场的导航信息、商家打折信息、各种广告信息等。下面就以将第一通信终端设置在公交汽车上（可以是公交汽车上的POS）为例，对本发明进行进一步的说明。由于公交汽车上的读卡装置较难实现联网，因此此处仅以第二通信终端（例如安装有射频SIM卡的手机）与后台服务器网络连接，且在后台服务器上实现目标信息的匹配过程为例进行说明。公交POS机中存储有公交POS机的编号作为其标识信息，手机本体不但可以实现电信功能，还可以通过安装的应用软件实现与后台服务器的互联网通信功能，射频SIM卡中安装公交一卡通应用软件，用于与公交POS机进行射频通信以完成扣费。本实施例中，后台服务器可以与安装于公交车上的GPS定位系统建立通信，通过GPS定位系统获取公交车行驶经过的当前位置信息，后台服务器可内设或外接一信息库，信息库中存储有，第一通信终端标识信息与目标信息索引表；该索引表中包括后台服务器所管理的多个公交POS机的编号信息、与每个公交POS机的编号信息对应的公交车的车牌号、与每个公交POS机的编号信息对应的公交车需行驶经过的多个典型位置信息（典型位置信息如站台），以及与每个典型位置信息对应的广告（如商家广告、商品广告等）等信息；进一步的，该信息库中还可存储各第二通信终端的标识信息，此处各第二通信终端的标识信息可以是SIM卡的卡号信息，或者手持终端上相应应用软件的用户名信息，也可以是各第二通信终端的编号等；此处仅以为SIM卡的卡号信息为例进行说明；信息库中存储有多个SIM卡的卡号信息、与各SIM卡的卡号信息对应的业务定制信息、与各SIM卡的卡号信息对应的消费记录，业务定制信息或消费记录都是持卡用户个人偏好的体现，便于后台服务器结合SIM卡的卡号信息从信息库中匹配到符合持卡用户偏好的惠明信；该信息推送过程具体包括如下流程：
步骤e1:用户持内置射频SIM卡的手机在公交POS机前刷卡，刷卡过程中，激发获取目标信息流程，公交POS机对射频SIM卡进行扣费，射频SIM卡获取公交POS机中预存的公交POS机的编号，也即第一通信终端的标识信息；
步骤e2：刷卡结束后，射频SIM卡按照短信、互联网等数据格式对第一标识信息进行封装；
步骤e3：射频SIM卡封装完成后，通过主动式命令通知手机本体，手机本体收到通知后，通过标准的SIM卡接口从射频SIM卡中获取该公交POS机的编号；
步骤e4：手机本体借助现有的通信网关，将封装有该公交POS机的编号的数据相应地以短信或互联网的方式发送给后台服务器；通信网关或后台服务器在接收手机本体发送的信息时，解析出其射频SIM卡的卡号，即获取手机本地的标识信息；
步骤e5：后台服务器根据该公交POS机的编号从信息库的第一通信终端标识信息与目标信息索引表中匹配出对应等么目标信息，具体过程为：根据该POS机编号配出对应的公交车的车牌号，并建立与该公交车上的GPS定位系统的通信连接，通过该公交车上的GPS定位系统获取该公交车当前的位置信息；后台服务器根据GPS定位系统反馈的该公交车当前的位置信息，以就近原则，从信息库中存储的与该公交POS机的编号对应的多个典型位置信息中，匹配出合适的一个或多个典型位置信息；后台服务器根据匹配出的典型位置信息从信息库中匹配与该典型位置信息对应的广告等信息。
步骤e6：后台服务器根据步骤e4中解析出的射频SIM卡的卡号，从信息库中匹配对应的定制信息或消费记录，根据匹配出的业务定制信息或消费记录从步骤e5中匹配到的广告等信息中筛选出符合用户个人喜好的信息作为最终目标信息；
步骤e7：后台服务器借助现有的通信网关通过短信、彩信或互联网等方式将得到的最终目标信息发送给手机本体。若使用互联网的方式将待推送的信息发送给手机本体，则由于互联网传输的数据量大，而且对信息类型没有要求，后台服务器可以向手机本体推送文本、图片、音频或视频任意类型的信息。
步骤e8：手机本体接收到后台服务器推送的短信、彩信、互联网数据之后，进行解析存储，供用户查阅推送信息。
上述过程利用第二通信终端与第一通信终端进行射频通信的过程，获取第一通信终端的标识信息，利用第二通信终端将第一通信终端的标识信息发送给后台服务器，后台服务器根据该标识信息向第二通信终端推送信息，不但可避免现有的近距离推送式中，第一通信终端需要与后台服务器联网的问题，同时还可以实现后台服务器向第二通信终端一对一的推送方式，实现了精准推送。后台服务器与第二通信终端之间可以通过短信、彩信或者互联网等方式实现信息推送，增加了推送的信息量，并且推送的信息类型不局限于文本形式，可以进行图片、音频和/或视频等类型信息的推送。后台服务器根据与第一标识信息绑定的第一通信终端的位置信息，结合持卡用户的定制信息、消费记录，实现了有针对性的信息推送。
实施例二：
在实施例一的图2-图4所示的通信系统中，涉及到第二通信终端与第一通信终端之间的射频通信，本实施例中的第二通信终端和第一通信终端都可通过多个不同的频点在多个不同的地址发送或接收数据，因此，在二者的射频通信过程中，则必然存在数据通信的频点以及如何提高通信过程中抗干扰能力等问题。
为了解决上述问题，在本实施例中，第一通信终端与第二通信终端在进行射频通信过程中，当一方要发送相关射频数据给另一方时，可选择设置为：
射频数据发送方在预设同步射频信道上通过预设同步地址发送包括发送方射频信道标识和发送数据地址的同步消息；
射频数据接收方在预设同步射频信道上从所述预设同步地址接收所述同步消息，并从所述同步消息中获取发送方射频信道标识和发送数据地址，根据获取的发送方射频信道标识得到发送方的射频信道；
射频数据接收方通过所述发送方射频信道从所述发送数据地址接收所述射频数据。
也即，在本实施例中，第一通信终端与第二通信终端在射频数据通信过程中，发送方可通过发送同步消息的方式向接收方发送同步消息，以告知接收方所采用的射频信道以及发送数据地址，可大大提高数据传输的可靠性，以及数据传输过程中抗干扰能力和有效性。
29. 在本实施例中，发送方射频信道标识和发送数据地址可采用随机数据，此时同步消息的格式如图6所示，该同步消息由消息方向字段、消息类型字段、消息长度字段、消息数据字段、消息校验字段组成。其中，消息数据字段中包含的为一随机数据。具体发送所述同步消息和进行射频数据交互时，可以采用分组的传输方式，此时发送方将同步消息、以及将要发送的射频数据进行分包，对拆分的数据包再加上数据类型字段、末包标识字段、数据包标识字段，组成数据包。发送方将组成的数据包在同步射频信道上从所述预设同步地址接收发送出去。在该情况下，射频数据发送方和射频数据接收方则分别对同步消息中的随机数据进行不可逆变换得到相应的发送方射频信道标识和发送数据地址。
本实施例中在不同的频点和地址发送和接收消息还可以采用发送方选定发送频点后在发射消息中置入一组希望接收的目标的地址信息，在选定的发送频点发送该带有地址信息的消息，接收端在该频点接收到消息后提取消息中的地址信息，如果地址信息是有效地址（例如发送对象中包括该接收端）则输出消息，否则不输出消息。当然在不同的频点和地址发送和接收消息也可以采用其他方式实现，在此不再赘述。
在本实施例中，所预设的同步射频信道可包括至少两个，射频数据发送方则可在其中的至少两个同步射频信道上发送相同的同步消息，这种设置方案可以避免在某一预设同步射频信道接收状态不佳的情况下，还可从其他预设同步信道接收同步消息，因此可进一步提高数据传送的可靠性。
在本实施例中，射频数据发送方可以在同一预设同步射频信道重复发送同步消息，重复发送的次数以及时间间隔都可根据实际情况设置，以保证处理速度较慢的射频数据接收方也能完整的接收发送方发送的射频数据。
本实施例中，射频信道标识可采用射频频点、 频段、逻辑信道、频道中的至少一种，下面以射频信道标识为射频频点为例进行说明。在图2-4所示的通信系统中，分别以第一通信终端100和第二通信终端200为射频数据发送端为例进行说明：
第一通信终端100为射频数据发送方时，在第一通信终端100的第一射频通信模块120将相关射频数据（例如目标信息、第一通信终端100的标识信息等）发送给第二通信终端200之前，在预设同步射频信道上通过预设同步地址发送包括其采用的射频信道标识和发送数据地址的同步消息；第二通信终端200的第二射频通信模块220用于在预设同步射频信道上从所述预设同步地址接收所述同步消息，从所述同步消息中获取第一通信终端100采用的射频信道标识和发送数据地址，根据获取的射频信道标识得到第一通信终端100采用的射频信道，通过该射频信道从所述发送数据地址接收第一通信终端100通过第一射频通信模块120所广播的射频数据。当然，第一射频通信模块120也可采用点对点的方式将该射频数据发送给第二通信终端。当射频信道标识和发送数据地址采用图6所示的随机数据时，第一射频通信模块120和第二射频通信模块220则分别对该随机数据进行不可逆变换得到相应的发送方射频信道标识和发送数据地址。
同理，为了进一步提高数据传输的可靠性，本实施例中第一通信终端100的第一射频通信模块120还可在至少两个同步射频信道分别广播相同的同步消息。同时，为了避免处理速度较慢的接收方也即第二通信终端200因为处理速度慢而导致数据接收失败的问题，本实施例中第一通信终端100的第一射频通信模块120还可在同一预设同步射频信道重复发送同步消息后再发送相应的射频数据。
第二通信终端200为射频数据发送方时，其第二射频通信模块220在将相关射频数据发送给第一通信终端100之前，在预设同步射频信道上通过预设同步地址发送包括其采用的射频信道标识和发送数据地址的同步消息；第一通信终端100的第一射频通信模块120该预设同步射频信道上从所述预设同步地址接收同步消息，从该同步消息中获取第二通信终端200采用的射频信道标识和发送数据地址，根据获取的射频信道标识得到发送方的射频信道，通过该射频信道从上述发送数据地址接收第二通信终端200发送的射频数据。
同理，在本实施例中，当射频信道标识和发送数据地址采用图6所示的随机数据时，第一射频通信模块120和第二射频通信模块220则分别对该随机数据进行不可逆变换得到相应的发送方射频信道标识和发送数据地址。
同时，为了进一步提高数据传输的可靠性，本实施例中第二通信终端200的第二射频通信模块220还可在至少两个同步射频信道分别广播相同的同步消息。同时，为了避免处理速度较慢的接收方也即第一通信终端100因为处理速度慢而导致数据接收失败的问题，本实施例中第二通信终端200的第二射频通信模块220还可在同一预设同步射频信道重复发送同步消息后再发送相应的射频数据。
下面基于图3所示的通信系统对本发明进行进一步的说明，如图7所示：
步骤701：第一通信终端100通过第一主控模块110控制第一网络通信模块130与后台服务器300建立连接；后台服务器300以有线或无线方式将相关数据（例如第一通信终端标识信息与目标信息索引表）发送给读卡装置100；读卡装置100的第一网络通信模块130接收后台服务器发送的数据，将其存储在第一存储模块140中；
步骤702：第一通信终端100通过第一主控模块110读取存储在第一存储模块140中的数据信息；
步骤703：第一通信终端100通过其第一射频通信模块120在预先设置的同步射频频点发送同步消息；
步骤704：第一通信终端100的第一主控模块110对同步消息携带的随机数据进行不可逆变换，用变换结果对应生成广播数据的数据发送频点（即发送方射频信道）和广播数据发送地址（即发送数据地址）；
同时，第二通信终端200的第二主控模块210对接收到的同步消息中包含的随机数据进行发送端相同的不可逆变换，用变换结果获得上述的数据发送频点和广播数据发送地址；
步骤705：第一通信终端100通过得到的数据发送频点在广播数据发送地址上发送所述从第一存储模块140读取的数据（以下仅以广播的方式进行说明，同时该数据也简称广播数据），第二通信终端200相应地在所述数据发送频点从广播数据地址进行广播数据接收。
图8示出了本实施例中利用射频通道进行信息推送的另一流程示意图，其包括：
步骤801：第一通信终端100通过第一主控模块110控制第一网络通信模块130与后台服务器300建立连接；后台服务器300以有线或无线方式将相关数据（例如第一通信终端标识信息与目标信息索引表）发送给读卡装置100；读卡装置100的第一网络通信模块130接收后台服务器发送的数据，将其存储在第一存储模块140中；
步骤802：第一通信终端100通过第一主控模块110读取存储在第一存储模块140中的数据信息；
步骤803：第一通信终端100通过其第一射频通信模块120在预先设置的第一同步射频频点发送同步消息；
步骤804：第一通信终端100通过其第一射频通信模块120在预先设置的第二同步射频频点发送同步消息；
步骤805：第一通信终端100的第一主控模块110对同步消息携带的随机数据进行不可逆变换，用变换结果对应生成广播数据的数据发送频点（即发送方射频信道）和广播数据发送地址（即发送数据地址）；
同时，第二通信终端200的第二主控模块210对接收到的同步消息中包含的随机数据进行发送端相同的不可逆变换，用变换结果获得上述的数据发送频点和广播数据发送地址；
步骤806：第一通信终端100通过得到的数据发送频点在广播数据发送地址上发送所述从第一存储模块140读取的数据（以下仅以广播的方式进行说明，同时该数据也简称广播数据），第二通信终端200相应地在所述数据发送频点从广播数据地址进行广播数据的接收。
可选地，本发明也可以在同步消息中不使用随机数据，而直接在同步消息中嵌入射频信道标识和发送数据地址，由此，无需进行上述的不可逆变换，直接读取同步消息中的信息即可获得射频信道标识和发送数据地址。
进一步地，本实施例中的射频数据接收方（例如第二通信终端20）0接收到广播数据后，还可进一步获取到的广播数据进行MAC（Message Authentication Codes）运算，与接收到数据中存放MAC（Message Authentication Codes）运算值的字段进行比较，如果相同，则认为该数据为合法的数据，如果不同，则认为该数据不合法。
同时，优选地，第二通信终端200在接收开始时开始计时，时间片T内根据此次接收到的广播数据条数而不超过设定显示的广播数据的总条数进行显示。
以上所述仅为本发明的较佳实施例，并不用以限制本发明，凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
