。Therefore, as shown at 17, the number of information signals specified by the calling signal can be changed as necessary.
上述したような従来の信号構成の内、第２図に基づいて
説明した前者の信号構成では情報信号の数は固定されて
いるため、長い情報は伝達できない、また、短い情報を
伝達する場合には必要以上に情報信号を送信することに
なり、無駄があるという欠点があった。Among the conventional signal configurations mentioned above, in the former signal configuration explained based on FIG. 2, the number of information signals is fixed, so long information cannot be transmitted, and when short information is transmitted, This method has the disadvantage of transmitting more information signals than necessary, which is wasteful.

欠点があった。On the other hand, in the latter signal configuration explained based on the $3 diagram, it is not determined in advance where within the group the paging signal will be transmitted. During the transmission time for the group to which it belongs, it is necessary to perform reception operations for all parts including information signals for other receivers, and there is a drawback that the battery saving effect is inferior to the method explained in Fig. ff12. Ta.

has been completed.

出信号に対応する情報信号の送信タイミングが指示され
る点が異なる。In addition, the signal NIItj& in the group is composed of a synchronization signal, a calling signal, and an information signal as in the conventional signal structure, but in the conventional structure, the information signal is located immediately after the calling signal indicating its destination. On the other hand, in the signal configuration of the present invention, the group is separated into a part where the paging signal is transmitted and a part where the information signal is transmitted, and the transmission timing of the information signal corresponding to the paging signal is determined by the reception control signal. The instructions are different.
情報信号送信タイミングの指示は、同期信号から敗えて
何ブロックＵから情報信号が始まるか、または、該受信
制御信号を含む呼出信号から数えて何ブロックロから情
報信号が始まるか等、情報信号の開始位置を受信制御信
号で送信することにより行ならことができる。Instructions for the information signal transmission timing include the number of blocks U from which the information signal starts from the synchronization signal, or the number U from which the information signal starts counting from the calling signal including the reception control signal, etc. This can be done by transmitting the starting position as a reception control signal.
また、該呼出信号に対応する情報信号の終了位置につい
でも同様に送信することも可能であるが、該呼出信号に
続く呼出信号内で送信される後続の情報信号の送信開始

ることが可能である。Although it is also possible to similarly transmit the end position of the information signal corresponding to the calling signal, it is also possible to detect the transmission start position of the subsequent information signal transmitted within the calling signal following the calling signal. Therefore, the end position can be omitted.
同様に、グループ内における呼出信号送信部分の終了位
置は該グループ内で最初に送信される呼出信号に対応す
る情報信号の開始位置を該呼出信号内の受信制御信号で
検出することにより可能である。Similarly, the end position of the calling signal transmission portion within a group can be determined by detecting the starting position of the information signal corresponding to the first calling signal transmitted within the group using the reception control signal within the calling signal. .
なお、識別コードについでは情報信号を呼出信号とｇ％
認した場合の誤受信、誤動作を防止するためには有効で
あるが省略しても支障ない。Regarding the identification code, the information signal is the calling signal and g%
Although this is effective in preventing erroneous reception and malfunctions when authentication is received, there is no problem in omitting it.
また、呼出信号内での識別コード、受信機番号、受信制
御の配置は６の方法にこだわらない。Furthermore, the arrangement of the identification code, receiver number, and reception control within the calling signal is not limited to the method described in 6.
本実施例においでは、このような信号構成となっている
から、受信機は自己が属するグループの最初に送信され
る同期信号を検出し、続いて１つまたは複数の呼出信号
を受信する。ここで呼出信号中に自己の受信機番号を検
出しなかった場合は、情報信号が送信される部分は受信
を休止し、電流の消費を減少することができる。In this embodiment, with such a signal configuration, the receiver detects the synchronization signal transmitted first in the group to which it belongs, and then receives one or more paging signals. Here, if the own receiver number is not detected in the calling signal, reception of the part where the information signal is transmitted is suspended, and current consumption can be reduced.
一方、呼出信号中に自己の受信機番号を検出した受信機
は、呼出信号中の制御信号により自己にあてた情報信号
が送信される位置を検出し、その部分のみを受信すれば
よい。On the other hand, a receiver that detects its own receiver number in a calling signal only needs to detect the position where the information signal addressed to itself is transmitted based on the control signal in the calling signal and receive only that part.
第４ｒＭは、このような動作を行なう受信機の構成の例

欠受信制御回路、２６はスイッチ、２７は電池を表わし
いる。4th rM is a diagram showing an example of the configuration of a receiver that performs such an operation, in which 21 is 7 antennas, 22 is a high frequency circuit, 23 is a decoder circuit, 24 is a signal processing circuit, and 25 is an intermittent reception control circuit. , 26 represents a switch, and 27 represents a battery.
同図において、送信装置から送信された信号はアンテナ
２１、高周波回路２２、デコーダ回路２３を通して信号
処理回路２４に入力される。In the figure, a signal transmitted from a transmitter is input to a signal processing circuit 24 through an antenna 21, a high frequency circuit 22, and a decoder circuit 23.

高周波回路２２お上りデコーダ回路２３への電流の供給
を行なうようスイッチ２６を制御する。The signal processing circuit 24 detects the timing at which the group to be received is transmitted using the synchronization signal, recognizes whether or not information is being transmitted to itself based on the receiver number in the calling signal, and uses the reception control signal to detect the timing when the group to be received is transmitted. The signal processing circuit 24 is an intermittent reception control circuit that detects the transmission timing of an information signal to a designated receiver and, if there is information transmission to itself, performs processing such as reception of the information signal at that transmission timing. From the start of the group to be received to the end of transmission of the calling signal based on the data from the receiver, and when information is transmitted to the receiver, the information signal is transmitted to the high frequency circuit 22 and the uplink decoder circuit 23. The switch 26 is controlled so as to supply the current.
受信機がこのように動作するので、信号発生装置は情報
内容に応じて必要なブロック数だけの情報信号を送信す
ることができる。Since the receiver operates in this manner, the signal generator can transmit information signals for as many blocks as necessary depending on the information content.
従って、第２図で説明した従来方式と異なり、本発明の
方式では長い情報内容を送信することが可能であり、短
い情報内容に対しても無駄が少ない。Therefore, unlike the conventional method described in FIG. 2, the method of the present invention allows long information contents to be transmitted, and there is little waste even for short information contents.
また、受信機の受信動作は第１図の２．４お上り５に示
すとおりであり、本発明の方式では第１図に示した例で
自己をの情報伝達がない場合には、グループ内において
受信動作を行なう時間の割合は第３図で説明した従来方
式と比較して５／１７となっており、バッテリーセービ
ング効果は約３．４倍向上する。Furthermore, the reception operation of the receiver is as shown in 2.4 Uplink 5 in Figure 1, and in the method of the present invention, in the example shown in Figure 1, if there is no information transmission within the group, In this case, the proportion of time for performing the receiving operation is 5/17 compared to the conventional method explained in FIG. 3, and the battery saving effect is improved by about 3.4 times.
なお、それぞれの受信機に対する情報伝達が一日に数回

日の大半を占めることとなるので、バッテリー七−ビン
グ効果の向上率は１呼出あた９の情報信号数が多（なる
ほど、すなわち伝達する情報内容が長くなるほど大きく
なる。Furthermore, if information is transmitted to each receiver only a few times a day, calls to receivers other than one's own will take up most of the day, so the improvement rate of the battery seven-bing effect will decrease. The number of information signals (9) per call is large (i.e., the longer the information content to be transmitted, the larger the number).
以上説明したように、本発明の方式では、バッテリーセ

率良く対応できる利点がある。As described above, the method of the present invention has the advantage of being able to efficiently handle various information contents without deteriorating the battery saving effect.
