Abstract: A steering rule provision method for traffic distribution in a network and a network entity performing the same network. A session management function (SMF) may transmit a first message including a multi-access rule (MAR) to a user plane function (UPF), when establishing or modifying a packet data unit (PDU) session for ATSSS (Access Traffic Steering, Switching, and Splitting). The SMF may receive a second message that is a response message to the first message from the UPF.

Abstract: A traffic distribution method through a multi-access network in a network and a network entity performing the same are disclosed. An access and mobility management function (AMF) may receive a PDU session modification request message including an ATSSS (access traffic steering, switching, and splitting) preference, which is a preference for an ATSSS rule, from an user equipment (UE) when a multi-access PDU session (MA PDU session) is established and the UE desires to change the ATSSS rule corresponding to the established MA PDU session. The AMF may transmit a first message including the ATSSS preference to a session management function (SMF).

Abstract: A packet data unit session establishment method and network entity performing the same is disclosed. User equipment (UE) may establish registration with the core network through a first access network when the UE is registered in a core network through a second access network belonging to the network and a first PDU session is established through the second access network. The UE may transmit a non-access stratum (NAS) message including a PDU session identifier (ID) that is the same as an ID of the first PDU session to an access and mobility management function (AMF).

Abstract: Provided is a random backoff apparatus and method for receiving augmented content that may prevent a delay or a down of a server caused by a plurality of receiving terminals accessing a server simultaneously, when a digital broadcasting system provides broadcast-based bidirectional broadcasting services over a communication network. That is, a technology for distributing receiving terminals accessing a server to receive augmented content, or accessing a home page of a corresponding program, based on metadata transferred from the digital broadcasting system to a broadcasting network. In a bidirectional digital method, a number of requests for access to the home page or the augmented content related to the program may be received from receiving terminals at one time. Accordingly, there is a desire for a method of preventing collision caused when a plurality of stations simultaneously access a single wireless channel.

Abstract: A method for processing a packet in a mobile communication network and a network element for performing the same. A first network element may receive a first data packet to be transmitted to a second network element via a third network element and add a header to the first data packet. The first network element may add time information associated with the first data packet to the header and transmit the first data packet with the header to the third network element.

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).
