【発明の詳細な説明】 ３、発明の詳細な説明 〔産業上の利用分野〕 本発明は多所−系無線通信における制御方式に関する。[Detailed description of the invention] 3. Detailed description of the invention [Industrial application field] The present invention relates to a control method in multi-location wireless communication.
親局統制形の多所−系無線通信においては子局から親局

てから初めて子局よりのデータを送出する必要がある。In the case of data communication from a slave station to a master station in master station controlled multi-site wireless communication, since the slave station does not have the right to transmit at all times, it requests transmission permission from the master station, and then sends data to the master station. It is necessary to transmit data from the slave station only after the

に回答する方式が一般的である。In this case, since the master station cannot determine the call occurrence status of the slave stations including other slave stations, it polls the slave stations to inquire whether there is a transmission request, and each slave station receives a call at a predetermined time. A common method is to reply to the master station using a slot (fixed depending on the system).

ングの効率が悪くなるという欠点があった。In the conventional method described above, the time slot for the reply from the slave station to the master station to the master station polling is fixed, so it is difficult to use a system in which the participation status of the slave stations changes during system operation (e.g., an outdoor mobile communication network). However, this method has the disadvantage that empty time slots may occur depending on the participation status of slave stations, resulting in poor polling efficiency.
本発明の目的は伝送効率のよい通信を行う無線通信方式
