Summary:To dynamically select a communication control device depending on a plurality of communication service requirements required by one UE.SOLUTION: In a communication system 1A, a selection MME 50 identifies a communication service used by a UE 10 from a first communication service and a second communication service, and refers to information in which the identified communication service is mapped to an address of an SGW80 that transmits/receives data for using the communication service. If the identified communication service is the first communication service, the selection MME 50 searches for an address of an SGW80 mapped to the service type of the first communication service, while it searches for an SGW80 different from that of the first communication control device if the identified communication service is the second communication service.SELECTED DRAWING: Figure 1 【課題】１つのＵＥが要求する複数の通信サービスの要件により動的に通信制御装置を選択する。【解決手段】通信システム１Ａにおいて、選択ＭＭＥ５０は、第１通信サービス及び第２通信サービスのうちから、ＵＥ１０が利用する通信サービスを特定し、特定した通信サービスと、当該通信サービスを利用するためのデータを送受信するＳＧＷ８０のアドレスとを対応付けた情報を参照する。特定した通信サービスが第１通信サービスである場合、第１通信サービスのサービスタイプに対応するＳＧＷ８０のアドレスを検索する一方、特定した通信サービスが第２通信サービスである場合、第１通信制御装置とは異なるＳＧＷ８０を検索する。【選択図】図１
