A Session Management Function, SMF, (650) determines that a first data path for a Packet Data Unit, PDU, session between an application client (611) and a first edge application server, EAS, (681) should be relocated from a first local PDU session anchor, PSA, (631) and a first uplink classifier and branching point, ULCL/BP, (621) to a second PSA (632) and a second ULCL/BP (622). Further, the SMF (650) determines an edge client subnet, ECS, associated with the second PSA (632). Further, the SMF (650) sends, to an application function, AF, (670) associated with the application client (611), a notification of the relocation. The notification includes an identifier of the ECS and a data network access identifier, DNAI, associated with the second PSA (632). From the AF (670), the SMF (650) receives a response that includes an identifier of a second EAS (682) and the DNAI associated with the second PSA (632). Based on the response, the SMF (650) establishes a second data path for the PDU session between the application client (611) and the second EAS (682) via the second PSA (632) and the second ULCL/BP (622).

A method of generating an uplink classifier (UL CL) via a session management function (SMF) includes: requesting a network data connection and analysis function (NWDAF) to provide data related to the UL CL for controlling a flow of network traffic; receiving the data related to the UL CL from the NWDAF; selecting at least one of a plurality of user plane functions (UPFs) based on the received data related to the UL CL; and creating the UL CL in the selected at least one UPF.

Provided is a terminal having: a transmitting unit configured to transmit to a base station a first uplink control channel including a HARQ (Hybrid Automatic Repeat Request) response related to a sidelink and an uplink shared channel; and a controlling unit configured to determine a process to be applied in a case where the first uplink control channel overlaps with the uplink shared channel at least in a time domain; wherein the transmitting unit transmits to the base station the first uplink control channel or the uplink shared channel, by applying the process.

A transmission timing determining method and apparatus are provided, to determine a transmission timing of an IAB node. The method is applied to a first node, and a second node may be an upper-level node or a donor node of the first node. The method includes: The first node receives control information from the second node, where the control information includes scheduling information of uplink transmission, and the control information includes first scrambling information. The first node determines a first timing type associated with the first scrambling information. The first node determines a transmission timing of the uplink transmission based on the first timing type.

A method and system for controlling uplink communication from a user equipment device (UE) that has at least two co-existing air-interface connections including a first air-interface connection with a first access node and a second air-interface connection with a second access node. An example method includes comparing a level of antenna pattern efficiency associated with the first air-interface connection with a level of antenna pattern efficiency associated with the second air-interface connection and, based at least on the comparing, configuring an uplink split ratio defining a distribution of uplink user-plane data flow of the UE between at least the first air-interface connection and the second air-interface connection. In an example implementation, this could involve configuring one of the air-interface connections as a primary uplink path to which the UE restricts its uplink communication unless and until a trigger occurs for transitioning the UE to operate in an split-uplink mode.

According to an aspect, a UE in an uplink split-bearer configuration is configured to transmit PDUs by a first RLC entity via a first uplink transmission path and/or by a second RLC entity via a second uplink transmission path. The UE determines a total amount of data volume from PDCP data volume and RLC data volume pending for initial transmission in the two RLC entities. The UE decides whether submission of PDCP data volume is allowed to either of the two RLC entities or to only the first RLC entity, based on whether the total amount of data volume meets or exceeds a first threshold. The UE also reports the PDCP data volume to both the first and second uplink transmission paths or only the first uplink transmission path, based on whether the total amount of data volume meets or exceeds a first threshold.

Traffic steering for non-public networks and public land mobile network (PLMN) clouds is provided. A method can include retrieving, by a system comprising a processor and associated with a communication network, a subscriber profile for a user equipment in response to receiving a request from the user equipment for access to the communication network, wherein the request comprises first data network information that is distinct from second data network information associated with the communication network; and, in response to an attribute of the subscriber profile being determined to be equal to a defined value, replacing, by the system, the first data network information in the request with the second data network information and routing, by the system, the request to core network equipment of the communication network.

A data flow manager distributes data of a data stream of a user equipment via at least a first communication link and a second communication link, wherein the second communication link is independent of the first communication link. The data flow manager includes: a network interface configured to receive a first status signal indicating a first link quality of the first communication link and a second status signal indicating a second link quality of the second communication link; and a processor configured to perform load-balancing by selecting a prioritization link from the first communication link or the second communication link independent of the first link quality and the second link quality provided that the first link quality is above a first quality threshold and the second link quality is above a second quality threshold.

The method includes: A terminal device determines that uplink transmission and sidelink transmission both exist; and when one or more of a first condition, a second condition, a third condition, and a fourth condition are not met, the terminal device performs the sidelink transmission; or when any one of one or more of a first condition, a second condition, a third condition, and a fourth condition is met, the terminal device performs the uplink transmission.

A method and system for operating a radio aware communication system includes receiving, by a content distribution system, a radio quality metric signal from a user device or a network; determining, by the content distribution system, a spectral efficiency for the user device based on the radio quality metric signal; receiving a capacity usage report from a first network; determining an available capacity of the first network based on the capacity usage report; determining a target available capacity utilization goal of the first network based on the available capacity; determining a target throughput based on the target available capacity utilization goal for communicating content to a user device and the spectral efficiency for the user device; and communicating the content to the user device using the target throughput through the first network.
