    • Multiplex transmission apparatus 10 on the transmitting side multiplexes received signals from non-voice signal input output apparatus 14 and voice signal input output apparatus 16, and also transmits the multiplexed signal from communications network 30 by digital portable telephone 12 on the transmitting side. The digital portable telephone transmits a signal per 20 msec, so that multiplex transmission apparatus 10 alternately transmits the voice signal and the non-voice signal at an interval of 20 msec, for example. Multiplex transmission apparatus 20 sorts out the voice signal and the non-voice signal from the supplied signal by checking the error detecting code of the supplied signal. Multiplex transmission apparatus 20 can judge the type of the signal according to the type of the error detecting code, because a different error detecting code is added to each signal.
    • 发送侧的多路复用发送装置10将来自非语音信号输入输出装置14和语音信号输入输出装置16的接收信号进行多路复用,并且还通过发送侧的数字便携式电话12发送来自通信网络30的复用信号。 数字便携式电话每20ms发送一个信号,所以多路传输装置10例如以20毫秒的间隔交替地发送语音信号和非话音信号。 复用发送装置20通过检查所提供的信号的检错码,从提供的信号中分出语音信号和非话音信号。 由于向每个信号添加了不同的检错码,所以多路传输装置20可以根据错误检测码的类型来判断信号的类型。

    • This invention provides a mobile communication system in which a call-incoming side can switch a communication line to an appropriate one which corresponds to a communication type requested by a transmitter's terminal. One example of its construction is as follows. A mobile station has a plurality of terminal units corresponding to plural types of communication and a call number is preliminarily assigned to each of them. A terminal unit in a telephone network uses a call number corresponding to a desired communication type when a datum is transmitted to the mobile station. The mobile station informs this call number to all of the terminal units which are connected to the mobile station. The respective terminal units inform the communication type to the mobile station only when the communication type corresponding to the call number can be handled. The mobile station informs this communication type contained in a reception call receiving signal to a mobile communication exchange. The mobile communication exchange selects a modulated/demodulator corresponding to this communication type.
    • 本发明提供了一种移动通信系统,其中呼入侧可以将通信线路切换到对应于由发射机终端请求的通信类型的适当通信线路。 其结构的一个例子如下。 移动台具有与多种通信对应的多个终端单元,并且预先分配呼叫号码。 电话网络中的终端单元在将数据发送到移动台时,使用与期望的通信类型对应的呼叫号码。 移动台向连接到移动台的所有终端单元通知该呼叫号码。 只有当可以处理与呼叫号码相对应的通信类型时,各个终端单元才向移动台通知通信类型。 移动站将包含在接收呼叫接收信号中的通信类型通知给移动通信交换机。 移动通信交换机选择对应于该通信类型的调制/解调器。

    • When the telephone number of digital portable telephone A is notified to reception notifying apparatus 3 (S101), the telephone number is stored (S102), and is forwarded to digital portable telephone B (S103). Next, when digital portable telephone B transmits a CALL SETUP signal and a sending number to digital portable telephone A (S104, S105), digital portable telephone A transmits a CALL PROC signal and an ALERT signal to digital portable telephone B (S106-S109). After that, information indicating that the busy line display is ON is forwarded to reception notifying apparatus 3 (S110), and the telephone number is deleted (S111). Furthermore, reception notifying apparatus 3 transmits a voice guidance to digital portable telephone A (S114).
    • 当数字便携式电话A的电话号码被通知给接收通知装置3时(S101),电话号码被存储(S102),并被转发到数字便携电话机B(S103)。 接下来,当数字便携式电话B向数字便携式电话A发送CALL SETUP信号和发送号码时(S104,S105),数字便携式电话A向数字便携式电话B发送CALL PROC信号和ALERT信号(S106〜S109) 。 之后,将表示忙线显示为ON的信息转发给接收通知装置3(S110),并删除电话号码(S111)。 此外,接收通知装置3向数字便携式电话A发送语音指导(S114)。
