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.
Claims8
A User Equipment (UE) comprising:
- transmission and reception circuitry;
- and
- a controller,
- wherein:
- the transmission and reception circuitry is configured to:
- transmit, to a core network, over 3GPP access, a Protocol Data Unit (PDU) Session Establishment Request message;
- and
- receive, from the core network, over the 3GPP access, a PDU Session Establishment Accept message, as a response to the PDU Session Establishment Request message, the PDU Session Establishment Accept message including routing rules for a Multi-Access PDU Session and identification information for establishing the Multi-Access PDU Session;
- the controller is configured to recognize that the Multi-Access PDU Session is established, based on receiving the PDU Session Establishment Accept message;
- a first communication path over the 3GPP access is established;
- the transmission and reception circuitry is further configured to receive, over non-3GPP access, a control message including the identification information;
- and
- a second communication path over the non-3GPP access is established.
A communication method performed by a User Equipment (UE), the communication method comprising:
- transmitting, a to a core network, over 3GPP access, a Protocol Data Unit (PDU) Session Establishment Request message;
- receiving, from the core network, over the 3GPP access, a PDU Session Establishment Accept message, as a response to the PDU Session Establishment Request message, the PDU Session Establishment Accept message including routing rules for a Multi-Access PDU Session and identification information for establishing the Multi-Access PDU Session;
- and
- recognizing that the Multi-Access PDU Session is established, based on receiving the PDU Session Establishment Accept message;
- establishing a first communication path over the 3GPP access;
- receiving, over non-3GPP access, a control message including the identification information;
- and
- establishing a second communication path over the non-3GPP access.
