本発明は、メツセージ送信に対し端末が受信一時不可の
ため再送信する必要がある場合、他の正常送信可能端末
への送信を優先してスケジュールする処理手順に関する
。[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a method for transmitting a message when a terminal is temporarily unable to receive the message and it is necessary to retransmit the message, giving priority to sending the message to another terminal that can normally send the message. Concerning the processing procedure to be scheduled.
従来の方式では、特開昭６２−４７７６０号公報の記載
のように、クラスタ端未配下のデバイスを処理の速いデ
バイスと遅いデバイスとにクラス分けし、処理の速いデ
バイスの送信を優先的に行うことにより、待ち時間を短
縮し、計算機の負荷を少なくしていた。In the conventional method, as described in Japanese Unexamined Patent Publication No. 62-47760, devices that are not under the cluster end are classified into fast processing devices and slow processing devices, and transmission is given priority to fast processing devices. This shortens waiting time and reduces computer load.
即ち、送信順位をデバイス毎に固定して、送信スケジュ
ールしているため、受信一時不可となる障害発生等によ
り、送信順位を動的に変更して、送信スケジュールする
という点については、配慮がなされていなかった。In other words, since the transmission order is fixed for each device and the transmission schedule is made, no consideration has been given to dynamically changing the transmission order and scheduling the transmission in the event of a failure that temporarily disables reception. It wasn't.
上記従来技術は、端末が受信一時不可となった端末も正
常送信可能端末も同一プライオリティで送信スケジュー
ルしているため、正常送信可能端末を優先して送信スケ
ジュールするという配慮がなされておらず、受信一時不
可の期間が長いと再送信しても再度受信一時不可となる
可能性が高く、再送信を何度も繰り返し、正常送信可能
端末への送信サービスが低下するという問題があった。In the above conventional technology, both the terminal temporarily unable to receive data and the terminal capable of normal transmission are scheduled to transmit with the same priority. If the temporary disabled period is long, there is a high possibility that even if the data is retransmitted, the reception will become temporarily disabled again, and retransmission is repeated many times, resulting in a problem in that the transmission service to terminals that can normally transmit is degraded.
本発明の目的は、送信スケジュール時受信一時不可端末
を送信一時保留状態にし、正常送信可能端末への送信サ
ービスを優先して行い、正常送信可能端末のサービス率
を向上させ、効率の良い送信スケジュールを行うことに
ある。An object of the present invention is to place terminals that are temporarily unable to receive data into a transmission hold state during a transmission schedule, give priority to transmission services to terminals that can normally send data, improve the service rate of terminals that can normally send data, and achieve an efficient transmission schedule. The goal is to do the following.
上記目的を達成するために、端末への送信時、受信一時
不可となった端末に対し送信一時保留という状態を設定
し、送信サービスの対象外として正常送信可能端末への
送信サービスを優先して行う。正常送信可能端末への送
信がすべて終了した時点で、送信一時保留という状態を
解除し、受信一時不可となった端末への再送信を行うよ
う送信スケジュールしたものである。In order to achieve the above purpose, when sending to a terminal, we set a status of temporary transmission hold for terminals that are temporarily unable to receive data, and prioritize sending services to terminals that can normally send data as they are not eligible for the sending service. conduct. The transmission schedule is such that when all transmissions to terminals that can normally transmit are completed, the temporary suspension of transmission is released and retransmission is performed to terminals that are temporarily unable to receive.
送信一時保留状態では該当端末を送信スケジュールの対
象外にし、正常送信可能端末への送信を先にスケジュー
ルし、正常送信可能端末への送信がすべて終了した時点
で送信一時保留状態を解除して、それらの端末への再送
信を行うようにする。In the transmission temporary hold state, the corresponding terminal is excluded from the transmission schedule, the transmission to the terminals that can normally send is scheduled first, and when the transmission to all the terminals that can normally send is completed, the transmission temporary hold state is released. Enable retransmission to those terminals.
それによって、受信一時不可となっている期間が長く、
再送信してもまた受信一時不可となる端末への再送信回
数を減らすことができるので、正常送信可能端末のサー
ビス率が向上し、効率の良い送信スケジュールが行える
。As a result, reception is temporarily unavailable for a long period of time,
Since it is possible to reduce the number of retransmissions to terminals that are temporarily unable to receive data even after retransmission, the service rate of terminals that can normally send data is improved, and an efficient transmission schedule can be performed.

Figure 3 shows the processing flow when receiving a report that reception is temporarily unavailable for transmission. As a result of transmission, check whether reception is temporarily disabled (32), and if reception is temporarily disabled, set the status flag 22 of the terminal management table 22.
-1 is put into a transmission temporary hold state (33), and it is checked whether there is a next transmission queue (34). If there is a transmission queue, check whether the status flag 23-1 of that terminal is in the transmission temporary suspension state (35), and if it is in the transmission temporary suspension state, find the next transmission queue 23-2, and similarly set the transmission temporary suspension state. I'll check what's going on. If there is no terminal whose transmission is temporarily on hold, transmission to that terminal is performed at that point (39). If all terminals in the transmission queue are in the transmission temporary hold state, all status flags are set to 2.
2-1 and 23-1 to reset the transmission temporary hold state 3g), - then switch to reception operation (40). After polling for reception is completed, a terminal with a message to be sent is searched for and the message is sent.

送信サービスが行える。According to this embodiment, when the terminal temporarily becomes unable to receive a message, the message must be retransmitted.
When there is a message to be sent on another terminal, the terminal that is temporarily unable to receive the message can be placed on hold temporarily, and the transmission can be given priority to the other terminal that has the message to be sent. Since it is possible to reduce the number of retransmissions to terminals that are temporarily unable to receive data even after retransmission, the response time of terminals that can normally transmit data is improved, and efficient transmission services can be provided.

It is possible to reduce the number of retransmissions to terminals that have a long period of time and are temporarily unable to receive data even after retransmission, so the response time of terminals that can normally transmit data is improved, and efficient transmission services can be provided.

ール方式。1. In a system consisting of multiple terminals under one line, when sending a message to a terminal, if the terminal is temporarily unable to receive the message, the message must be retransmitted after a period of time. At this time, a state of temporary transmission hold is set for terminals that are temporarily unable to receive messages, and messages are scheduled to be sent to terminals that can normally send messages with priority. A message retransmission schedule method is characterized in that the message retransmission is performed when all messages are completed, thereby preventing a drop in transmission service to terminals that can normally transmit.
