A method and device for transmitting a service are provided, which comprises: when a requirement of the service changes, the network apparatus instructs, via a control signaling, the mobile station to replace the first resource allocation parameter set with a second resource allocation parameter set in a SPS manner, and the first resource allocation parameter set is used to transmit a first service which is being transmitted.

A distributed radio frequency communication system facilitates communication between a wireless terminal and a core network. The system includes a remote radio unit (RRU) coupled to at least one antenna to communicate with the wireless terminal. The RRU includes electronic circuitry to perform at least a first portion of a first-level protocol of a radio access network (RAN) for communicating between the wireless terminal and the core network. The system also includes a baseband unit (BBU) coupled to the core network, and configured to perform at least a second-level protocol of the RAN. A fronthaul link is coupled to the BBU and the RRU. The fronthaul link utilizes an adaptive fronthaul protocol for communication between the BBU and the RRU. The adaptive fronthaul protocol has provisions for adapting to conditions of the fronthaul link and radio network by changing the way data is communicated over the fronthaul link.

A service request processing method, a related apparatus, and a system are provided. In the service request processing method provided in embodiments of the present invention, after receiving a service request reported by a network element, a load balancer first determines whether status information of a data node that corresponds to the service request indicates that the data node is available; and rejects, if the status information indicates that the data node is unavailable, to deliver the service request to an application node.

The present disclosure provides a file delivery method. The file delivery method includes receiving a task request for a file delivery task sent by a target node to request a file; determining according to the task request whether there are completed nodes, the completed nodes being other target nodes that have completed a file delivery task delivering the file; designating, if there are completed nodes, a node from the completed nodes as a source station corresponding to the task request; designating, if there are no completed nodes, a source server as the source station corresponding to the task request; and delivering the file to the target node through the designated source station.

A method for providing a service based on a user scenario, a terminal device, and a system. The terminal device perceives the user scenario with low power consumption, and a cloud-side service open platform determines a corresponding scenario package based on the user scenario, where the scenario package includes a plurality of pre-orchestrated services for the user scenario. The service open platform pushes data related to the determined scenario package to the terminal device, and the terminal device displays entry interfaces of the plurality of services, and provides a corresponding service based on an operation performed by a user on the entry interface.

Embodiments of this application disclose a data transmission system, including an over the air OTA server, a master electronic control unit ECU, and a node ECU. The master ECU is configured to obtain a size of a target software package from the OTA server. The master ECU is further configured to transmit to a node ECU, the size of the target software package, or obtain a size of a remaining storage space of the node ECU from the node ECU.

Disclosed herein is a method including receiving, from a user application, data to be transmitted from a source address to a destination address using a single connection through a network; and splitting the data into a plurality of packets according to a communication protocol. For each packet of the plurality of packets, a respective flowlet for the packet to be transmitted in is determined from a plurality of flowlets. Assignment of the flowlets to the packets can be dynamically adjusted based on utilization of the flowlets.
