說明書

The UE NBIFOM capability is the NBIFOM capability of the UE 10. The UE NBIFOM capability is identification information for each UE 10 indicating whether or not capability of establishing the first PDN connection is supported. In other words, the UE NBIFOM capability is identification information indicating whether or not the NBIFOM function is supported for each UE 10. More specifically, for example, the NBIFOM capability may include “allowed” or “Not allowed”.

Note that the NBIFOM function may be information indicating the possession of the function of establishing the multi-access PDN connection based on the NBIFOM.

Alternatively, the UE NBIFOM capability may be identification information indicating that the UE 10 has the capability of establishing the first PDN connection. That is, the existence of the UE NBIFOM capability in the storage of the UE 10 may mean that the UE 10 has the function of establishing the first PDN connection.

In other words, the UE NBIFOM capability may be identification information indicating that the UE 10 supports the NBIFOM function. That is, the existence of the UE NBIFOM capability in the storage of the UE 10 may mean that the UE 10 supports the NBIFOM function.

FIG. 8B illustrates an example of the UE context for each PDN connection. As illustrated in FIG. 8B, the UE context for each PDN connection includes at least a PDN connection ID, an APN in Use, an IP address, a Default Bearer, a WLAN offload ability, a UE allowed mode, and an Operation mode.
