    Abstract: Methods and system for supporting traffic steering through a service function chain, the service function chain comprising at least one data processing function. An aspect of the disclosure provides for a method for steering traffic of a packet data unit (PDU) performed by a session management function. The method includes receiving PCC rules from a policy control function, the PCC rules including information comprising at least one of service function chain information; final delivery indication; and selective traffic steering information and associated parameters. The method further includes configuring at least one user plane function (UPF) according to the information. In some embodiments the configuring the at least one UPF includes instructing a first UPF to detect traffic according to the packet detection rules and route the received packet according to the forwarding action rules.

    Abstract: A sleep-aiding audio signal updating method and apparatus in the artificial intelligence (AI) field is provided. The method includes: obtaining a first biological signal collected when a first audio signal in a sleep-aiding audio library is played, where the first biological signal is a biological signal of a first user; determining a sleep quality of the first user based on the first biological signal; and updating the sleep-aiding audio library based on the sleep quality of the first user, so that a sleep-aiding audio signal can be updated, to provide a proper sleep-aiding audio signal for a user, and ensure a sleep-aiding effect.

    Abstract: A network function and a method for associating a UE of a UE group to a PDU session with in a CN. The NF establishes a shared PDU session for the UE group before all of the UEs in the UE group register with the CN and binds a UE that has not yet registered with the CN to the shared PDU session when the UE registers with the CN, provided the UE will share at least one of a UL UP connection and a DL UP connection associated with the shared PDU session. The NF may be an SMF.

    Abstract: The present disclosure relates to central units and remote units. One example central unit includes at least one digital-to-analog converter (DAC), at least one first electro-optical converter configured to convert an analog electrical signal output by the DAC into an analog optical signal, at least one first optical processor configured to process the analog optical signal output by the first electro-optical converter, where the first optical processor includes at least one of at least one first optical filter, at least one first optical phase shifter, and at least one first optical power amplifier, a first multiplexer configured to combine analog optical signals output by the first optical processor into one analog optical signal, and a first demultiplexer configured to decompose the one analog optical signal into multiple analog optical signals at different wavelengths.

    Abstract: An aspect of the disclosure provides for a method for user equipment (UE) internet protocol (IP) address management. The method includes sending by an application function (AF), a request to a policy control function (PCF), the request including information identifying traffic and an indication that a UE IP address associated with the traffic should be preserved. The method further includes sending by the PCF, to a session management function (SMF) being responsible for managing a Protocol Data Unit (PDU) session associated with the traffic, a policy and charging control (PCC) rule including the indication. In some embodiments, the request is sent by the AF to the PCF via a network exposure function (NEF). In some embodiments, the method further includes managing, by the SMF, the UE IP address according to the PCC rule. In some embodiments, the managing includes preserving the UE IP address for a PDU session associated with the traffic. In some embodiments, the preserving includes preventing reselection of a protocol data unit (PDU) session anchor (PSA) to which the UE IP address is associated.

    Abstract: Aspects of the disclosure provide a system and method used for allowing a path selection or reselection (hereby (re)selection). In some embodiments data packets for a session between a UE and an application system (AS) can utilize a pre-established user plane path between the AS and an access node (AN) which serves the UE. This can allow for faster session set-up times as a new user plane (UP) path need not be established for every new session if existing UP paths can be utilized. Some embodiments allow an application aware (re)selection of the user plane.
