To provide a communication system and a communication method that satisfy various requirements.SOLUTION: The communication system comprises a base station that performs standard-compliant communication to a terminal, and an allocation determination device that receives an allocation request from the base station and determines a communication resource. The allocation determination device includes a first allocation determination unit and a second allocation determination unit. The first allocation determination unit outputs first allocation information within a first time after having received the allocation request. The second allocation determination unit outputs second allocation information within a first time after having received the allocation request. When one of the first allocation information and the second allocation information satisfies constraints defined by a communication standard, the allocation determination device transmits the one of the first allocation information and the second allocation information that satisfies the constraints to the base station. The base station communicates with the terminal using the resource corresponding to the first allocation information or the second allocation information transmitted from the allocation determination device.SELECTED DRAWING: Figure 13 【課題】種々の要求を満たす通信システム及び通信方法を提供すること。【解決手段】実施形態に係る通信システムは、端末に対して規格に従う通信を行う基地局と、基地局からの割当要求を受信し、通信リソースを決定する割当決定装置と、を具備する。割当決定装置は、第１割当決定部と、第２割当決定部と、を具備する。第１割当決定部は、割当要求を受信してから第１時間以内に第１割当情報を出力する。第２割当決定部は、割当要求を受信してから第１時間以内に第２割当情報を出力する。割当決定装置は、第１割当情報と第２割当情報の一方が通信規格が規定する制約を満たす場合には制約を満たす第１割当情報と第２割当情報の一方を基地局に送信する。基地局は、割当決定装置から送信された第１割当情報又は第２割当情報に対応するリソースを使用して端末と通信する。【選択図】図１３
