A cellular data communication network includes a BBU connected to a UPF by an IP network. A first translation module translates GFP packets into IP packets transmitted over the IP network. A second translation module translates the IP packets back into IP packets and forwards the IP packets to the UPF. A PFCP proxy intercepts control packets of the UPF. Information snooped by the PFCP proxy is provided to a routing/SDN controller that programs the translation modules and a routing module to perform routing of packets in bypass of the UPF.

The present disclosure provides a data transmission method, related devices and system. The method includes: an upper layer transmits a data packet to a corresponding Service Data Adaptation Protocol (SDAP) entity, according to at least one of a network slice identifier, an SDAP identifier, a flow identifier or a session identifier; the SDAP entity adds the flow identifier to the data packet, and transmits the data packet with the flow identifier to a Packet Data Convergence Protocol (PDCP) entity corresponding to a Data Radio Bearer (DRB), according to a corresponding relationship between the SDAP entity and the DRB.

In one example embodiment, a server obtains a first indication of a first identifier associated with a user equipment in a wireless network, and first telemetry data associated with the first indication. The server obtains, from a network entity including a base station entity serving wireless communication in the wireless network, a second indication of the first identifier and second telemetry data associated with the second indication. The server determines that the first indication and the second indication match. In response to determining that the first indication and the second indication match, the server correlates the first telemetry data and the second telemetry data.

A first communication device is configured to process packets that conform to a first physical layer (PHY) protocol for wireless vehicular communications and packets that conform to a second PHY protocol for wireless vehicular communications. The first communication device determines that one or more second communication devices neighboring the first communication device are not capable of processing packets that conform to the second PHY protocol. The first communication device transmits a first packet to a third communication device that is configured to process packets that conform to the first PHY protocol and packets that conform to the second PHY protocol. The first packet indicates that the one or more second communication devices neighboring the first communication device are not capable of processing packets that conform to the second PHY protocol to inform the third communication device of the one or more second communication devices.

The present disclosure relates to a method of transmitting a packet by an Integrated Access and Backhaul (IAB) node in a wireless communication system. In particular, the method includes the steps of: receiving, from a first node, an indication indicating that a congestion problem occurs between the first node and a second node; if the packet is to be transmitted to other node via the first node, transmitting the packet to the first node; and if the packet is to be transmitted to the second node via the first node, transmitting the packet to a third node.

A network device may receive packets and may calculate, during a time interval, an arrival rate and a departure rate, of the packets, at one of multiple virtual output queues. The network device may calculate a current oversubscription factor based on the arrival rate and the departure rate, and may calculate a target oversubscription factor based on an average of previous oversubscription factors associated with the multiple virtual output queues. The network device may determine whether a difference exists between the target oversubscription factor and the current oversubscription factor and may calculate, when the difference exists, a scale factor based on the current oversubscription factor and the target oversubscription factor. The network device may calculate new scheduling weights based on prior scheduling weights and the scale factor, and may process packets received by the multiple virtual output queues based on the new scheduling weights.

Systems and methods are provided for receiving data indicating a spatial distribution and 802.11ax capabilities of access point radios and of client devices in a network, assigning the access point radios as either first access point radios or second access point radios, the first access point radios conducting data transmission using an 802.11ax wireless standard and the second access point radios conducting data transmission using legacy wireless standards, based on the data, determining whether any of the client devices are to be steered to a different access point radio based on the 802.11ax capabilities of the client devices, and in response to determining that a client device is to be steered to a different access point radio, steering the client device to a first access point radio or a second access point radio.

This discloses relates to an application program control method and apparatus. The method includes that: an application entity receives a notification message transmitted by a core entity (320), the notification message indicating that a change in a parameter value of a quality of service notification control (QNC) of a non-guaranteed bit rate (GBR) bearer flow satisfies a reporting condition; and the application entity controls an application program according to the notification message (340). According to this application, the application entity may perceive a change in a wireless network state of the non-GBR bearer flow, and further actively control running of the application program according to the change.

A wireless communication section wirelessly communicates with a communication terminal present in a target space. An information acquiring section acquires a value representing congestion of a target space. A learned model is a model that has been trained using training data including a value representing the congestion of a target space used for learning, a bandwidth, a channel, and throughput. An AI processing section inputs the value representing the congestion of the target space acquired by the information acquiring section to the learned model and acquires a bandwidth and a channel output by the learned model. A bandwidth controller causes the wireless communication section to perform wireless communication using the bandwidth acquired by the AI processing section. The channel controller causes the wireless communication section to perform wireless communication using the channel acquired by the AI processing section.

The present disclosure relates to methods and apparatuses. According to some embodiments of the disclosure, a method performed by a communication device, includes: receiving, from a base station, a first configuration information indicating a threshold to configure the communication device, wherein the threshold is associated with data volume; determining whether congestion happens at the communication device based on the threshold; and transmitting a congestion indication to a first parent node via a Backhaul Adaptation Protocol (BAP) signaling message when it is determined that the congestion happens at the communication device.
