Summary:PROBLEM TO BE SOLVED: To allow communication with a communication device to be resumed within a short time when a protocol is switched during communication with the communication device.SOLUTION: When a protocol is switched, an access point BS stores, prior to that, a communication parameter of a communication device DT1 during data transmission in a communication parameter storage unit 22, and switches the protocol without performing a termination notification procedure with the communication device DT1. Then, when the protocol is switched again to the original protocol, the access point restores the communication state of the access point BS for the communication device DT1 on the basis of the communication parameter stored in the communication parameter storage unit 22, and resumes the reception of sensor data transmitted by the communication device DT 1 after that.SELECTED DRAWING: Figure 2 【課題】通信デバイスとの通信中にプロトコルの切替えを行った場合に当該通信デバイスとの間の通信を短時間に再開できるようにする。【解決手段】アクセスポイントBSにおいて、プロトコルを切替える際に、それに先立ちデータ送信中の通信デバイスDT1の通信パラメータを通信パラメータ記憶部22に保存し、上記通信デバイスDT1との間の終了通知手順を行わずにプロトコルを切替える。そして、上記プロトコルに再度切替えられた場合に、上記通信パラメータ記憶部22に保存されている通信パラメータをもとに、上記通信デバイスDT1に対するアクセスポイントBSの通信状態を復元し、以後通信デバイスDT1から送信されたセンサデータの受信を再開するようにしたものである。【選択図】図2
