1. A User Equipment (UE) comprising:
- a controller;
LTE interface circuitry; and
WLAN interface circuitry,whereinthe LTE interface circuitry is configured to;
transmit a second Packet Data Network (PDN) connectivity request message to a Mobility Management Entity (MME) in order to establish a PDN connection over a 3GPP access, andreceive an Activate default Evolved Packet System (EPS) bearer context request message from the MME,while the UE has established the PDN connection over the 3GPP access, the WLAN interface circuitry is configured to;
transmit a PDN connectivity request message to a Trusted WLAN Access Gateway (TWAG) in a case of adding a WLAN access to the PDN connection; and
receive a PDN connectivity accept message as a response to the PDN connectivity request message from the TWAG,in a case where a Network-based IP flow mobility (NBIFOM) mode of the PDN connection is a UE-initiated NBIFOM mode, the PDN connectivity request message includes first information indicating a default access selected by the UE,the PDN connectivity accept message includes second information indicating a default access determined by a Policy and Charging Rule Function (PCRF), based on the first information, andthe controller is configured to;
consider the default access indicated by the second information, based on reception of the PDN connectivity accept message; and
route a packet not matching any routing filter to the default access indicated by the second information.

Abstract
A method of communication control and the like accompanied with a multi-access PDN connectivity establishment request from a terminal device. Communication control for establishing a multi-access PDN connection is performed based on a response to a PDN connectivity establishment request from the terminal device. Communication control is performed for transmitting and/or receiving user data by using one or more default bearers for a multi-access PDN connection.

6. A communication method performed by a User Equipment (UE), the communication method comprising:
-
transmitting a second PDN connectivity request message to a Mobility Management Entity (MME) in order to establish a Packet Data Network (PDN) connection over a 3GPP access; receiving an Activate default Evolved Packet System (EPS) bearer context request message from the MME; while the UE has established the PDN connection over the 3GPP access, transmitting a PDN connectivity request message to a Trusted WLAN Access Gateway (TWAG) in a case of adding a WLAN access to the PDN connection; and receiving a PDN connectivity accept message as a response to the PDN connectivity request message from the TWAG, wherein in a case where a Network-based IP flow mobility (NBIFOM) mode of the PDN connection is a UE-initiated NBIFOM mode, the PDN connectivity request message includes first information indicating a default access selected by the UE, and the PDN connectivity accept message includes second information indicating a default access determined by a Policy and Charging Rule Function (PCRF), based on the first information, and the communication method further comprising; considering the default access indicated by the second information, based on reception of the PDN connectivity accept message; and routing a packet not matching any routing filter to the default access indicated by the second information. - View Dependent Claims (7, 8, 9)
