Next, the UE 10 transmits a PDN connectivity request to the TWAG 74 (S1802). The UE 10 may transmit the PDN connectivity request including at least the PDN connectivity request message identity (PDN connectivity request message ID), the Procedure transaction identity (Procedure transaction ID), the Request type, and the PDN type. Furthermore, the UE 10 may include at least the first identification information in the PDN connectivity request. Moreover, the UE 10 may include the Access Point Name (APN) and/or Protocol Configuration Options (PCO) and/or the Traffic Flow Templates (TFTs) in the PDN connectivity request. Note that the UE 10 may transmit the PCO including the first identification information and/or the TFT.
Here, the first identification information may be the UE NBIFOM capability representing that the UE 10 supports the NBIFOM. Note that the NBIFOM capability may be information indicating the possession of the function of establishing the multi-access PDN connection based on the NBIFOM. As described above, the UE 10 may transmit the PDN connectivity request including the first identification information to request the establishment of the multi-access PDN connection based on the NBIFOM.
The PDN connectivity request message ID may be a message type representing the PDN connectivity request message. The Procedure transaction ID may be information for identifying the PDN connectivity procedure.
