Zusammenfassung:PROBLEM TO BE SOLVED: To provide a radio communication system which can properly form a temporal group while taking positions of members which posses radio devices into consideration.SOLUTION: A radio device 1A suggests formation of a temporal group. A radio device 1B and 1C responds to the suggestion for forming the temporal group. The radio device 1A calculates positional information of the radio device 1A and sends the information to the radio device 1B and 1C. The radio device 1B and 1C calculates positional information of the radio device 1B and 1C, and calculates distance between the radio devices 1A and 1B and distance between the radio devices 1A and 1C on the basis of the positional information of the radio device 1A and the positional information of the radio devices 1B and 1C (Steps S106 and S107). The radio device 1B joins the temporal group when the distance between the radio device 1A and 1B is within a prescribed distance (Step S108), and the radio device 1C does not join the temporal group when the distance between the radio device 1A and 1C is within a prescribed distance (Step S109). The radio device 1A forms the temporal group with the radio device 1A and the radio device 1B.SELECTED DRAWING: Figure 2A 【課題】無線機を所持するメンバの位置を考慮して、一時的なグループを適切に作成することできる無線通信システムを提供する。【解決手段】無線機1Aは一時グループの形成を発起する。無線機1B及び1Cは一時グループの形成の発起に応答する。無線機1Aは、無線機1Aの位置情報を算出し、無線機1B及び1Cに送信する。無線機1B及び1Cは、無線機1B及び1Cの位置情報を算出し、無線機1Aの位置情報と無線機1B及び1Cの位置情報とに基づいて、無線機1A,1B間の距離、無線機1A,1C間の距離を算出する(ステップS106及びS107)。無線機1Bは無線機1A,1B間の距離が所定の距離以内であるので一時グループに参加し(ステップS108)、無線機1Cは無線機1A,1C間の距離が所定の距離以内であるので一時グループに参加しない(ステップS109)。無線機1Aは、無線機1Aと無線機1Bとで一時グループを形成する。【選択図】図2A
