One disclosure of the present specification provides a method for operating in relay user equipment (UE). The method may comprise the steps of: receiving a communication request message directly from a first remote UE; performing a procedure for establishing an access and mobility management function (AMF) entity and a protocol data unit (PDU) session; and storing mapping information between an identifier of a PCS link with the first remote UE and an identifier of the PDU session on the basis of the PDU session being established for an unstructured PDU session type for unstructured traffic.

A mobile communication device for receiving an ad hoc temporary upgrade in quality of service (QoS). The mobile communication device comprises a processor, at least one cellular radio transceiver, a non-transitory memory, and an ad hoc service upgrade application. When executed by the processor, the application monitors wireless cellular communication on a network via the at least one cellular radio transceiver, detects a significant delay in the communication, generates a prompt on a GUI, the prompt comprising a plurality of options for an ad hoc temporary upgraded QoS, where each option is associated with a time period. The application further, based on a user input, requests a preferred roaming list (PRL) associated with the temporary upgraded QoS, receives the PRL, wherein the PRL is associated with providing the upgraded QoS on an allocated spectrum, activates the received PRL, and upon expiration of the time period, deactivates the received PRL.

The technology of this application relates to a data transmission method. The method includes an application server sending a subscription request to a core network element, to subscribe to a notification indicating whether transmitting data of a first service to first user equipment in a multicast mode is supported, so that a transmission mode of the data of the first service can be flexibly selected based on a subscription result.

This application provides a communication method and apparatus. One example method comprises: obtaining, by a first communication apparatus, a first service that is to be sent from the first communication apparatus to a second communication apparatus; determining, by the first communication apparatus, a second quality of service (QoS) parameter based on the first service, wherein the second QoS parameter indicates a QoS requirement for sending the first service from the first communication apparatus to the second communication apparatus; sending, by the first communication apparatus, the second QoS parameter to a first relay communication apparatus, wherein the first relay communication apparatus is a relay communication apparatus between the first communication apparatus and the second communication apparatus; and receiving, by the first communication apparatus, a third QoS parameter from the first relay communication apparatus, wherein the third QoS parameter is used to determine a QoS parameter corresponding to the first service on a first link, and the first link is a link between the first communication apparatus and the first relay communication apparatus.

First information received by a first MLD on a first link is used to determine whether a BSS configuration of a second link is updated. In response to the BSS configuration of the second link not being updated, the first MLD directly transmits a data frame on the switched-to second link or the second link whose status is transited, and the data frame is not transmitted until a beacon frame is received and a latest parameter of the BSS configuration is obtained on the switched-to second link or the second link whose status is transited. A waiting time occurring before the data frame is transmitted is reduced.

Provided are a QoS control method and apparatus, and a readable storage medium. A source UE sends request information to a target UE according to the triggering of an application, wherein the request information comprises QoS information of service data that is transmitted between the source UE and the target UE; and when receiving the request information issued by the source UE to the target UE, a relay UE can obtain QoS information of the service data that is transmitted between the source UE and the relay UE, and QoS information of the service data that is transmitted between the relay UE and the target UE.

A configuration method for a sidelink relay architecture and a device are disclosed. The method is executed by a relay terminal, and includes: receiving configuration information, where the configuration information is used for configuring a mapping relationship between a universal user network interface Uu bearer and at least one of the following of a remote terminal: a sidelink bearer or quality of service QoS flow information, and the Uu bearer is a bearer between the relay terminal and a network device.

A method for delivering quality of service to a moving user equipment in a computer network, the method including: identifying a moving user equipment on the computer network; predicting a path of travel for the user equipment; determining a load of a cell in the path of travel; determining a traffic action response based on the load of the cell; and providing the traffic action. A system for delivering quality of service to a moving user equipment in a computer network, the system including: a location module configured to identify a moving user equipment on the computer network; an analysis module configured to predict a path of travel for the user equipment; a load module configured to determine a load of a cell in the path of travel; and a traffic action module configured to determine a traffic action response based on the load of the cell and provide for the traffic action.

A method, a device, and a non-transitory storage medium are described in which a policy control event exposure service is provided. The service may include a policy control event exposure service that supports quality of service (QoS)-based event subscription and access and mobility (AM)-based event subscription. The service may notify network function consumers when a QoS-based event or an AM-based event occurs.

A unified data management function (UDM) in a communication system including: a processor, a memory, and a communication device, wherein the processor executes a program stored in the memory to perform: determining an update of a UE parameter of a terminal to update the UE parameter and notifying the updated UE parameter to an AMF connected to the terminal by invoking a service operation for an SDM notification is provided.
