Summary:To perform communication via a bearer with better utilization efficiency of network resources.SOLUTION: In a packet transfer system 6 including a UE3, a common U-plane function 2 including a transfer function, and multiple NSI5 for providing services, respectively, to the UE3, a logical communication channel, i.e., a bearer, is created between the UE3 and the transfer function, and when a packet imparted with service identification information for identifying the NSI5 is received by the transfer function from the UE3 via the bearer, the packet is transferred to the NSI5 corresponding to the service identification information. A wireless network section may be included between the UE3 and the transfer function. The UE3 may be prohibited to impart the service identification information to the packet, based on the UE3 or the communication destination there, i.e., the NSI5.SELECTED DRAWING: Figure 1 【課題】ネットワークリソースの利用効率がより良い、ベアラを介した通信を行うこと。【解決手段】UE3と、転送機能を含むNSI間共通U−plane機能2と、UE3に対してそれぞれサービスを提供する複数のNSI5とを含むパケット転送システム6であって、UE3と転送機能との間に論理的な通信路であるベアラを作成し、NSI5を識別するサービス識別情報が付与されたパケットを、UE3からベアラを介して転送機能が受信した場合に、当該サービス識別情報に対応するNSI5へ当該パケットを転送する。UE3と転送機能との間に無線ネットワーク区間を含んでもよい。UE3又はUE3の通信先であるNSI5に基づいて、UE3がパケットにサービス識別情報を付与することを禁止してもよい。【選択図】図1
