Description

技术领域
本发明实施例涉及通信技术领域, 尤其涉及一种拥塞控制方法、 装置 及系统。 背景技术
由于智能终端的普及以及各种应用的层出不穷,长期演进(Long Term Evolution, 简称: LTE) 系统中的基站 ( Evolved Node B, 以下简称: eNB ) 越来越可能遭遇拥塞, gPeNB的通信能力无法满足在该 eNB下通信的所有 用户设备 (user equipment, 以下简称: UE ) 的上行通信需求。 因此, 需 要一定的机制来缓解拥塞。
现有技术中的一种缓解拥塞的方式是: 按照业务优先级或服务质量 ( Quality of Service, 以下简称: QoS ) 需求, 降低一部分低优先级或 QoS 需求较低的业务 (例如 web、 收取邮件) 的服务质量, 但这种方式的前提 是网络为 UE的不同业务建立了不同承载,然而当前 LTE系统的部署中大多 是多种业务映射到同一个承载, 此时无法通过区分承载来达到仅降低低优 先级或低 QoS要求的业务的目的, 因此也就无法实现缓解拥塞的目的。 发明内容
