1. A User Equipment (UE) comprising:
LTE interface circuitry configured to:
transmit a Packet Data Network (PDN) connectivity request message to a Mobility Management Entity (MME), in order to establish a PDN connection; and
receive an Activate default EPS bearer context request message from the MME; and
control circuitry, wherein
the PDN connectivity request message includes first information indicating a requested Network-based IP Flow Mobility (NBIFOM) mode,
the PDN connectivity request message further includes a request type and a Protocol Configuration Option (PCO),
the control circuitry is configured to set the request type to information indicating an initial connectivity request,
the PCO includes information indicating a request for use of NBIFOM,
the Activate default EPS bearer context request message is a response message to the PDN connectivity request message, and includes second information indicating an NBIFOM mode,
the Activate default EPS bearer context request message further includes information indicating that the request for use of NBIFOM is accepted, and
based on the reception of the Activate default EPS bearer context request message, the control circuitry is configured to:
consider that the NBIFOM is applied to the PDN connection; and
consider the second information as the NBIFOM mode for the PDN connection.
