Abstract
To provide a communication control means for establishing a session suitable for a terminal apparatus connecting to multiple access networks of various kinds and a network apparatus, a user data communication control means suitable for a terminal apparatus that has established sessions via multiple access networks and a network apparatus, and the like. This provides a communication control means suitable for a terminal apparatus and a network apparatus that support connection to multiple access networks of various kinds.
Claims11
A terminal apparatus comprising:
- a transmission and/or reception unit configured to receive a session establishment accept message including at least first identification information, from a core network or an access network via a Non-3GPP access in a first session establishment procedure;
- and
- a controller configured to establish a session supporting Access Traffic Splitting with the core network, based on the first session establishment procedure, wherein
- the first identification information is information indicating that the session supporting Access Traffic Splitting is established, and
- the session is a session in which communication through a first communication path via the Non-3GPP access is possible.
A control apparatus included in a core network, the control apparatus comprising
- a transmission and/or reception unit configured to receive a session establishment request message including at least first identification information, from a terminal apparatus via a 3GPP access in a session establishment procedure, wherein
- the transmission and/or reception unit transmits a session establishment accept message including at least second identification information, to the terminal apparatus via a 3GPP access in the session establishment procedure,
- the first identification information is information indicating that establishment of a session supporting Access Traffic Splitting is requested, and
- the second identification information is information indicating that establishment of a session supporting Access Traffic Splitting is established.
A gateway for connecting an access network and a core network, the gateway comprising
- a transmission and/or reception unit configured to transmit a session establishment accept message including at least first identification information, to a terminal apparatus via a Non-3GPP access in a session establishment procedure, wherein
- the first identification information is information indicating that a session supporting Access Traffic Splitting is established.
