Description

电信设备和用于该设备的基带处理器
技术领域
本发明涉及电信设备和用于该电信设备的基带处理器。
背景技术
已知的电信设备包括:
-壳体,
-壳体内的用户标识模块(SIM)卡保持器;以及
-具有基带处理器以及接收和发射多个电话呼叫的无线电收发机的印刷电路板。
典型的,电信设备的印刷电路板也具有一种机械装置,该机械装置具有与插入到卡保持器的SIM卡建立有线通信的6个连接引线。有线通信的可靠性取决于6个连接引线和SIM卡上的相应的连接垫之间的电接触的质量。
可能由于卡保持器上的机械压力发生较差的电接触。较差的电接触反过来引起网络丢失。
发明内容
因此,本发明的一个目的是提供更可靠的电信设备。
考虑上述和其他目的,依照本发明提供一种电信设备,其中印刷电路板包括适于使用无线通信与插入到卡保持器的SIM卡通信的第二无线电收发机。
在上述电信设备中,具有与SIM卡建立有线通信的连接引线的机械装置被第二无线电收发机代替。因此,无线通信代替有线通信。无线通信对卡保持器上的机械压力的灵敏度较低。因此,印刷电路板和插入到卡保持器的SIM卡之间的数据交换的可靠性得到改进。
依照本发明的设备,其中:
-基带处理器是位于保护性包装内的包括至少一个电子芯片的集成电路,以及
-第二收发机设置在相同的保护性包装内,该设备在印刷电路板上提供了更多的空间,因为由第二收发机引起的基带处理器尺寸的增加小于用于与SIM卡的有线通信的具有连接引线的机械装置的尺寸。
依照本发明的设备,包括:
-盖子(54),保护至少部分印刷电路板不受辐射电场的影响,以及
-天线(32),连接到第二收发机用于从插入到卡保持器的SIM卡读取数据,该天线被放置在屏蔽盖子上,该设备同样的为印刷电路板提供了更多空间。
依照本发明的设备,其中SIM卡保持器受到设置在天线前面的壳体的内部表面的保护,改进了印刷电路板和SIM卡之间通信的可靠性。
依照本发明的设备,其中第二收发机适用于使用13.56MHz的射频通信,并且其中第二收发机还适用于与设置在壳体外的其他设备通信,极大的降低了制造成本。
本发明也涉及用在该电信设备中的基带处理器。
根据下面的说明书,附图和权利要求,本发明的上述和其他方面将会变得清楚。
附图说明
图1是包括电信设备的无线电话系统的示意图;
图2是图1中电信设备的横截面;以及
图3是操作图1中电信设备的方法流程图。
具体实施方式
图1显示了包括网络基站4和无线电电信设备的无线电话系统2。为了示意的目的,无线电电信设备是无线蜂窝移动电话机6。电话机6使用无线信号8与基站4通信。
基站4包括向/从电话机6发送/接收无线电信号8的发射机和接收机。
电话机6包括壳体12和印刷电路板14,印刷电路板14具有射频收发机16和基带处理器18来接收或发射无线电信号8。印刷电路板14设置在壳体12内。壳体12具有一个开口,用户打开该开口把SIM卡插入电话机6。
收发机16连接到天线20以接收或发射无线电信号8。
收发机1 6把接收的无线电信号转化为基带信号,并且反之依然。换言之,收发机1 6的主要任务是从无线电信号中去除载波或把这种载波增加到基带信号。基带信号通过把收发机16连接到处理器18的线路22在处理器18和子系统16之间交换。
处理器18控制电话机6的设备的每个部分。尤其的,处理器18适用于从插入到卡保持器28的SIM卡26读取数据。卡保持器28设置在壳体12中。
处理器18是位于保护性包装内的包括一个或多个电子芯片的集成电路。在本实施例中,处理器18还包括位于它的保护性包装内并连接到天线32的无线电收发机30。收发机30适用于使用NFC(近距离通信)技术与其他设备建立无线通信链路。NFC技术是已知的并且价格便宜。该技术基于13.56MHz的射频,允许在小于10cm的距离内高达1Mbit的数据交换速率的无线通信。
在图1中,计算机36代表使用NFC技术与电话机6通信的设备。为此,计算机36包括连接到天线40用于与收发机30建立无线通信链路42的无线电收发机38。
收发机30同时与一个或多个设备建立几条无线通信链路。
SIM卡26是通过无线通信链路44与收发机30通信的无源数据载体。例如,SIM卡26是包括连接到天线48的无线电收发机46的非接触智能卡,其都结合在塑料卡中。卡26可以插入到卡保持器28或从卡保持器28中移除。
照例,SIM卡还包括为了操作电话6而存储有用数据的存储器50,有用数据例如是电话号码等等。存储器50链接到收发机26。
在图1中,为了简单,卡保持器28并不与板14交迭。图2以横截面显示了与板14的位置相对的卡保持器28的位置。在横截面中,板14是水平的并且设置在壳体12的底部。在图2中,电话机6的元件具有与图1中相同的参考标记。
如图2所示,屏蔽盖子54固定在板14的上部。盖子54用于保护板14不受外部辐射电磁场的影响。例如,至少部分盖子54设置在处理器18的上部来保护该处理器。天线32固定在盖子54上部从而节省板14的空间。例如,天线32设置在位于处理器18上方的盖子54的表面上。
受壳体12保护的卡保持器28最小化了天线32和卡26的天线48之间的距离。这增加了链路44的可靠性。这里,卡保持器28位于天线32上方。
下面参考图3描述电话机6的操作。
首先,在步骤70,电话机6的使用者打开壳体12并把卡26插入卡保持器28。
然后,在步骤72,电话机6被供电并且收发机30与卡26建立链路44。一旦链路44被建立,在步骤74,处理器18以非接触的方式通过链路44从卡26读取数据。例如,收发机30发射具有13.56MHz频率的调制高频信号。相应的,卡26依靠另一调制方式通过链路44发射所要求的数据。
同时或此后,在并行的步骤76中,收发机30建立链路42与计算机36通信。在步骤78,一旦链路42被建立,通过链路42在计算机36和处理器18之间交换数据。
