Abstract
Provided are a communications control method, etc., for multi-access PDN connection establishment requests from terminal devices. Provided is communication control accompanied with establishment of a multi-access PDN connection or with rejection of establishment of a multi-access PDN connection, based on a response to a PDN connectivity establishment request from a terminal device.
Claims14
A terminal device comprising:
- a WLAN interface unit configured to receive a Packet Data Network (PDN) Connectivity Accept message from a Trusted WLAN Access Gateway (TWAG) in order to establish a PDN connection, wherein
- the PDN Connectivity Accept message includes information indicating a Network-based IP Flow Mobility (NBIFOM) mode.
A Trusted WLAN Access Gateway (TWAG) comprising:
- an IP mobile communication network interface unit configured to transmit a Packet Data Network (PDN) Connectivity Accept message to a terminal device, wherein
- the PDN Connectivity Accept message includes information indicating a Network-based IP Flow Mobility (NBIFOM) mode.
A terminal device comprising:
- a WLAN interface unit configured to receive an authentication response message from an enhanced Packet Data Gateway (ePDG) in order to establish a Packet Data Network (PDN) connection, wherein
- the authentication response message includes information indicating a Network-based IP Flow Mobility (NBIFOM) mode.
An enhanced Packet Data Gateway (ePDG) comprising:
- an IP mobile communication network interface unit configured to transmit an authentication response message to a terminal device, wherein
- the authentication response message includes information indicating a Network-based IP Flow Mobility (NBIFOM) mode.
A PDN gateway (PGW) comprising:
- an IP mobile communication network interface unit configured to transmit a Create Session Response message to a Trusted WLAN Access Gateway (TWAG) or an enhanced Packet Data Gateway (ePDG), wherein
- the Create Session Response message includes information indicating a Network-based IP Flow Mobility (NBIFOM) mode.
