To preferably perform packet retransmission in the wireless section.SOLUTION: A base station device 20 functioning as a communication control device is provided between a wireless section and a wired section in a communication path used by a communication terminal 10 in communication with a server 40, and performs communication with a communication terminal through the wireless section. The base station device 20 comprises: a communication information acquisition unit 21 for acquiring information on the requested quality of communication between the communication terminal 10 and the server 40; a retransmission control parameter determination unit 22, on the basis of the information on the requested quality acquired in the communication information acquisition unit 21, for determining the retransmission control parameter used when controlling retransmission of the packet addressed to the communication terminal 10 in the wireless section; and a retransmission processing unit 25, on the basis of the retransmission control parameter 22 determined by the retransmission control parameter determination unit 22, for controlling retransmission of packets addressed to the communication terminal in the wireless section.SELECTED DRAWING: Figure 3 【課題】無線区間でのパケット再送を好適に行う。【解決手段】通信制御装置として機能する基地局装置２０は、通信端末１０がサーバ４０との間の通信において利用する通信経路における無線区間と有線区間との間に設けられて、通信端末との間で無線区間を介して通信を行う。基地局装置２０は通信端末１０とサーバ４０との間の通信の要求品質に係る情報を取得する通信情報取得部２１と、通信情報取得部２１において取得された要求品質に係る情報に基づいて、無線区間において通信端末１０宛のパケットの再送を制御する際に使用する再送制御パラメータを決定する再送制御パラメータ決定部２２と、再送制御パラメータ決定部２２において決定された再送制御パラメータ２２に基づいて、無線区間における通信端末宛のパケットの再送を制御する再送処理部２５と、を有する。【選択図】図３
