Abstract
Provided is communication control accompanied with establishment of a multi-access PDN connection or with rejection of establishment of a multi-access PDN connection, on the basis of a response to a PDN connectivity establishment request from a terminal device. This provides a method of communication control and the like accompanied with a multi-access PDN connectivity establishment request from the terminal device.
Claims28
A User Equipment (UE) comprising:
- WLAN interface circuitry configured to:
- transmit a Packet Data Network (PDN) connectivity request message to a Trusted WLAN Access Gateway (TWAG), in order to establish a PDN connection;
- and
- receive a PDN connectivity accept message from the TWAG, wherein
- the PDN connectivity request message includes first information indicating a requested Network-based IP Flow Mobility (NBIFOM) mode, and
- the PDN connectivity accept message is a response message to the PDN connectivity request message, and includes second information indicating an NBIFOM mode.
A Trusted WLAN Access Gateway (TWAG) comprising:
- IP mobile communication network interface circuitry configured to:
- receive a Packet Data Network (PDN) connectivity request message from a User Equipment (UE);
- and
- transmit a PDN connectivity accept message to the UE, wherein
- the PDN connectivity request message includes first information indicating a requested Network-based IP Flow Mobility (NBIFOM) mode, and
- the PDN connectivity accept message is a response message to the PDN connectivity request message, and includes second information indicating an NBIFOM mode.
A User Equipment (UE) comprising:
- WLAN interface circuitry configured to:
- transmit an authentication request message to an enhanced Packet Data Gateway (ePDG), in order to establish a Packet Data Network (PDN) connection;
- and
- receive an authentication response message from the ePDG, wherein
- the authentication request message includes first information indicating a requested Network-based IP Flow Mobility (NBIFOM) mode, and
- the authentication response message is a message to be received after the transmission of the authentication request message, and includes second information indicating an NBIFOM mode.
An enhanced Packet Data Gateway (ePDG) comprising:
- IP mobile communication network interface circuitry configured to:
- receive an authentication request message from a User Equipment (UE);
- and
- transmit an authentication response message to the UE, wherein
- the authentication request message includes first information indicating a requested Network-based IP Flow Mobility (NBIFOM) mode, and
- the authentication response message is a message to be transmitted after the reception of the authentication request message, and includes second information indicating an NBIFOM mode.
A PDN Gateway (PGW) comprising:
- IP mobile communication network interface circuitry configured to:
- receive a create session request message from a Trusted WLAN Access Gateway (TWAG) or an enhanced Packet Data Gateway (ePDG);
- and
- transmit a create session response message to a transmission source of the create session request message, wherein
- the create session request message includes first information indicating a Network-based IP Flow Mobility (NBIFOM) mode, and
- the create session response message is a response message to the create session request message, and includes second information indicating an NBIFOM mode.
