The WLAN offload ability is identification information indicating whether traffic connected through this APN can perform offload to the WLAN by utilizing a cooperative function between the WLAN and the 3GPP, or maintains the 3GPP connection. The WLAN offload ability may vary for each RAT type. Specifically, the LTE (E-UTRA) and the 3G (UTRA) may have different WLAN offload ability.
The PDN GW identity is identification information for identifying the PGW 30 utilized in this APN. This identification information may be a Fully Qualified Domain Name (FQDN) or an IP address.
The NBIFOM permission is information indicating that this PDN connection has established the multi-access PDN connection. In other words, the NBIFOM permission indicates that the first PDN connection has been established.
That is, the fact that the TWAG 74 has stored the NBIFOM permission means that this PDN connection is the first PDN connection.
The NBIFOM permission is identification information that is stored by the TWAG 74 based on the PDN connection being established.
Specifically, for example, the HSS 55 data for each PDN connection including the APN 1 may include the NBIFOM Permission, and the HSS-55 data for each PDN connection including the APN 2 need not include the NBIFOM Permission.
In other words, the PDN connection based on the APN 1 may be the first PDN connection, and the PDN connection based on the APN 2 cannot be the first PDN connection.
