Abstract: Provided are a congestion control method and device, and a base station. The congestion control method includes: determining whether a traffic data flow transmitted by a base station is congested; setting an Internet protocol (IP) data packet in the traffic data flow when the traffic data flow transmitted by the base station is congested, where the set IP data packet is used for indicating that the traffic data flow transmitted by the base station is congested. The present disclosure solves the problem in the existing art that user throughput is affected because a base station only determines whether the base station is congested.

Abstract: This disclosure is generally directed to wireless communication systems and methods and relates particularly to monitoring and reporting of uplink and downlink data transmission latency according to a configurable timing and data granularity. The various example implementations disclosed herein provide a mechanism for the network side of the wireless network system to flexibly configure the monitoring, measurement, calculation, and reporting of information related to downlink and uplink data transmission latency in a collaborative manner among the various network nodes, devices and entities, and between the control-plane and user-plane of the wireless network. The disclosed implementations provide a configurable network latency segmentation scheme in addition to configurable timing, data or data flow granularity, content, and format for the monitoring/measurement/calculation/reporting of relevant latency information. The various network devices or nodes are thus coordinated under the adaptive configuration by the network to efficiently monitor, measure, calculate, and report latency information adapted to the need of a particular application and particular data communication session. For the reporting latency information in the user-plane, a special-purpose Protocol Data Unit (PDU) is also designed and constructed.
