Abstract
A traffic distribution method through a multi-access network in a network and a network entity performing the same. A first device belonging to the network may trigger a change to an ATSSS (access traffic steering, switching, and splitting) rule corresponding to an established multi-access PDU session (MA PDU session) when the MA PDU session is established. A session management function (SMF) may transmit a first message including the changed ATSSS rule to an access and mobility management function (AMF).
Claims20
A method for modifying a packet data unit (PDU) session in a network, the method comprising:
- triggering, by a first device belonging to the network, a change to an ATSSS (access traffic steering, switching, and splitting) rule corresponding to an established multi-access PDU session (MA PDU session) when the MA PDU session is established;
- and
- transmitting, by a session management function (SMF), a first message including the changed ATSSS rule to an access and mobility management function (AMF).
A method for modifying a packet data unit (PDU) session in a network, the method comprising:
- establishing a multi-access PDU session for an ATSSS (access traffic steering, switching, and splitting) function;
- triggering, by a first device, a change of an ATSSS rule when the ATSSS rule is changed;
- transmitting, by a session management function (SMF), a first message including the changed ATSSS rule to an access and mobility management function (AMF);
- and
- transmitting, by the AMF, a second message including the changed ATSSS rule to an access network.
A network entity that controls modification for a packet data unit (PDU) session in a network, the network entity comprising:
- a processor controlling a change to an ATSSS (access traffic steering, switching, and splitting) rule corresponding to an established multi-access PDU session (MA PDU session) when the MA PDU session is established in user equipment (UE);
- and
- a network interface transmitting a PDU session modification message including the changed ATSSS rule to another network entity.
