Abstract

Embodiments of the present invention provide a congestion control method and device. The congestion control method comprises: acquiring a stream control transmission protocol (SCTP) resource state, determining whether the SCTP resource state satisfies a congestion determining condition, and when the SCTP resource state satisfies the congestion determining condition, performing SCTP congestion control processing. In the embodiments of the present invention, the influence of CPU processing capability on signaling congestion is considered and congestion control is performed, which reduces delivery of SCTP signaling or reduces service requests, alleviates the insufficiency of SCTP resources when an eNB is under impact of a large amount of signaling, avoids faults and breakdown of devices under the impact of a large amount of signaling, achieves the purpose of SCTP congestion control, and ensures normal operation of an eNB service.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular, to a congestion control method and device for a Stream Control Transmission Protocol (Steam Control Transmission Protocol, SCTP). Background technique [0002] Long Term Evolution (LTE) system control plane messages are used to ensure the normal operation of the system, the normal establishment and exit of service connections, etc., so the reliability of the control plane messages is very important in the LTE system. The S1 signaling between the enhanced base station (Evolved Node Base station, eNB) and the mobility management entity (Mobility Management Entity, MME) and the X2 signaling between the eNBs are transmitted based on the SCTP protocol. [0003] In a high-load scenario, due to the large number of SCTP messages or the large message traffic, the system is highly congested and can hardly handle other services. In order to prevent SCTP signaling conge...
