Summary:To provide a communication control device, a communication system, a communication control method, and a program that reduce a possibility of running out of a buffer memory of a mobile communication device that receives data in an environment in which a plurality of mobile communication devices may desire to select the same mobile device as a destination for data transmission.SOLUTION: In a communication control processing method, a second mobile communication device that receives a request for permission to transmit data from a first mobile communication device determines whether data transmission is allowed on the basis of a free capacity of a buffer memory for storing received data and a reserved capacity indicated by reservation setting of the buffer memory, and when it is determined to allow data transmission, the second mobile communication device updates a reservation setting such that the capacity for the received data corresponding to the data transmission is added to the reserved capacity, and transmits a response indicating that the data transmission is allowed to the first mobile communication device.SELECTED DRAWING: Figure 5 【課題】複数の移動通信装置が同一の移動通信装置をデータの送信先として選択することを望む可能性のある環境において、データを受信する移動通信装置のバッファメモリの容量が不足する可能性を低減する通信制御装置、通信システム、通信制御方法及びプログラムを提供する。【解決手段】通信制御処理方法は、第1の移動通信装置から、データ送信の許可を求める要求を受信した第2の移動通信装置は、受信したデータを記憶するバッファメモリの空き容量及びバッファメモリの予約設定が示す予約済み容量に基づいて、データ送信を許可するか否かを決定し、データ送信を許可すると決定された場合に、データ送信に対応する受信データのための容量が予約済み容量に追加されるように予約設定を更新し、データ送信を許可することを示す応答を第1の移動通信装置へ送信する。【選択図】図5
