Congestion control method, device and system

Abstract

Embodiments of the present invention provide a congestion control method, device and system. The method includes: the network side device obtains service attribute information of different services carried by the UE. The service attribute information includes service type or QOS requirements or service priority. The network side device obtains the service attribute information of different services carried by the UE. After the device detects congestion based on the system load, it sends congestion control information to the UE based on the service attribute information, so that the UE processes the services within the UE bearer based on the congestion control information. The congestion control method, device and system provided by the embodiments of the present invention can better alleviate congestion without interrupting services for high-priority services within the UE bearer.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a congestion control method, device, and system. Background technique [0002] Due to the popularity of smart terminals and the emergence of various applications, the base station (Evolved Node B, hereinafter referred to as: eNB) in the Long Term Evolution (LTE) system is more and more likely to encounter congestion, that is, the communication capability of the eNB cannot meet the requirements. Uplink communication requirements of all user equipment (user equipment, UE for short) communicating under the eNB. Therefore, a certain mechanism is needed to alleviate congestion. [0003] A way of alleviating congestion in the prior art is: according to business priority or Quality of Service (QoS for short) requirements, reduce some services with low priority or low QoS requirements (such as web, receiving emails) service quality, but the premise o...

[0003] A way of alleviating congestion in the prior art is: according to business priority or Quality of Service (QoS for short) requirements, reduce some services with low priority or low QoS requirements (such as web, receiving emails) service quality, but the premise of this method is that the network establishes different bearers for different services of the UE. However, in the current LTE system deployment, most services are mapped to the same bearer. The purpose of the business with low priority or low QoS requirements, so the purpose of alleviating congestion cannot be achieved
