說明書
Note that the PGW_A 1310 may be a gateway device selected by using the APN 1. The PGW_B 1320 may be a gateway device selected by using the APN 2. Moreover, the PGW_A 1310 and the PGW_B 1320 may be the PGW 30. Furthermore, the selection of gateway using the APN 1 and/or the APN 2 may be performed by the TWAG 74 included and arranged in the access network B and/or the MME 40 included and arranged in the core network 90.
In addition, the gateway device selected by using the APN 1 and the gateway device selected by using the APN 2 may be the same gateway device. In this case, the PGW_A 1310 and the PGW_B 1320 may be the same device.
Note that the first PDN connection may be constituted of a transfer path between the UE 10 and the PGW 30 through the access network B. Thus, the first PDN connection may be constituted of a transfer path that is a combination of a transfer path between the UE 10 and the TWAG 74 and a transfer path between the TWAG 74 and the PGW_B 1320. Here, the transfer path may be a bearer.
In addition, the second PDN connection may be constituted of a transfer path between the UE 10 and the PGW 30 through the access network A. Thus, the second PDN connection may be constituted of a transfer path that is a combination of a transfer path between the UE 10 and the eNodeB 45, a transfer path between the eNodeB 45 and the SGW 35, and a transfer path between the SGW 35 and the PGW_B 1320. Here, the transfer path may be a bearer.
