時間Ｔ１において送信データ長を含む発呼要求を行う。First, in FIG. 2, when the command station shifts from the control channel Cch to the communication channel Sch, it polls the mobile stations 1 to 3, and the mobile stations 1 to 3 each check the transmission data length at time T1 shown in FIG. Make a call request including
この場０合、例として移動局１〜３の順で送信データ長
が短くなるものとする。In this case, it is assumed that the transmission data length becomes shorter in the order of mobile stations 1 to 3, for example.

。The command station determines transmission priority by comparing the remaining time of the call time of the call channel Sch with the transmission time corresponding to the transmission data length of each mobile station 1.2.3, and also uses the call channel Sch for voice communication. Each mobile station 1 to 3 is notified that it will be used for data transmission instead of data transmission, and then the mobile station l with the longest transmission data length is notified that it is permitted to make a call request.
移動局１は、この通知を受けてデータを上記フレーム構
成で時分割で送信し、再度指令局から許可通知を受ける
と、順次データを時分割で送信する。Upon receiving this notification, the mobile station 1 transmits the data in the above-mentioned frame structure in a time-division manner, and upon receiving the permission notification from the command station again, it sequentially transmits the data in a time-division manner.
指令局は、優先順位の最も高い移動局ｌからのデータを

える。When the command station receives data from the mobile station l with the highest priority, it calculates the remaining time of the call time of the above-mentioned call channel Sch and the transmission time corresponding to the transmission data length of each mobile station 1.2.3. Based on the comparison result, transmission priority is given to the mobile station whose transmission time corresponding to the transmission data length is shorter than the remaining time.

３からのデータを受信し、制御チャネルＣｃｈに戻る。FIG. 2 shows a case where the transmission time corresponding to the transmission data length of mobile station 1.2 is longer than the remaining time of this call time. Mobile station 3 is given transmission priority and mobile station 3
The mobile station 3 receives data from the mobile station 3 and returns to the control channel Cch.
したがって、指令局は、通話チャネルＳｃｈの時間内で
移動局１．３からのデータを時分割で受信するために、
通話チャネルＳｃｈを効率的に用いてデータを伝送する
ことができる。Therefore, in order to receive data from the mobile station 1.3 in a time-sharing manner within the time of the communication channel Sch, the command station performs the following steps.
Data can be transmitted using the communication channel Sch efficiently.
尚、この場合、−通話チャネルＳｃｈの時間内のデータ

When the mobile stations 1 to 3 are polled as in the case of FIG.
Each of these makes a call request including the transmission data length in the header part of the signal as shown in FIG.
指令局は同様に、通話チャネルＳｃｈの通話時間の残り

を行う。Similarly, the command station determines the transmission priority by comparing the remaining time of the communication channel Sch with the transmission time corresponding to the transmission data length of each mobile station 1.2.3, and also determines the transmission priority of the communication channel Sch. Each mobile station 1 to 3 is notified that it will be used for data transmission rather than voice communication, and then the mobile station 1 with the longest transmission data length is notified that it is permitted to make a call request.
したがって、指令局は、第３図（ａ）に示すように優先
順位の最も高い移動局１に残っていたデータを受信する
ことができ、また、第３図（ｂ）に示すように次の通話
チャネルＳｃｈで優先順位の比較的低い移動局２．３か
らのデータを順次時分割で受信することができる。Therefore, the command station can receive the data remaining in the mobile station 1 with the highest priority as shown in FIG. Data from the mobile station 2.3, which has a relatively low priority, can be sequentially received in a time-division manner on the communication channel Sch.
尚、指令局は、移動局１〜３からのデータを受信するこ

。If the command station is unable to receive the data from the mobile stations 1 to 3, the command station sends the data to the mobile stations 1 to 3 on the next communication channel Sch, as shown in FIG. 3(c). After polling, call requests from mobile stations 1 to 3 are ignored,
Permission to transmit the data is sequentially given to the mobile stations 1 to 3 that could not receive the data according to the priority order, and the mobile stations receive the data.
