說明書
It has also been discussed for the NBIFOM to stipulate an operation mode indicating an endpoint node that is capable of initiating switching of a communication path. Specifically, it has been discussed for the NBIFOM to classify an operation mode into a UE-initiated mode and a Network-initiated mode.
A terminal device and each device included in a core network and an access network are capable of transmitting/receiving data on a communication path through an appropriate access network for each application by using an NBIFOM function.
Furthermore, an endpoint node configured to initiate switching a flow of the multi-access PDN connection established by using the NBIFOM function can be configured based on the operation mode.

For the NBIFOM, a detailed procedure for establishing a multi-access PDN connection has not been stipulated. Specifically, details of successful procedure and failure procedure in the multi-access PDN connectivity establishment procedure have not been stipulated.
More specifically, details of accept means and reject procedure from a network for a request of establishing the multi-access PDN connection in which a terminal device supports an NBIFOM function, have not been clarified.
