Self-adaptive flow control method and device, computing equipment and storage medium

Abstract

The invention discloses a self-adaptive flow control method and device, computing equipment and a storage medium. The method comprises the following steps: acquiring the historical registration request quantity of each AMF network element in a large area and the equipment processing capability data of an IWF network element; counting the number of first registration requests initiated by each AMF network element in the current period; calculating a second registration request number corresponding to each AMF network element in the next period, and issuing the second registration request number to each corresponding AMF network element, so that each AMF network element deploys a flow control strategy according to the second registration request number. According to the method, the IWF network elements are periodically predicted and the number of the second registration requests is updated in real time without manual intervention, so that the processing capacity of each AMF network element in a signaling storm scene is maximized, the IWF network elements are effectively protected, the interruption of services in a large area is avoided, and the influence of the services is reduced to the greatest extent.

Description

technical field [0001] The present invention relates to the technical field of flow control, in particular to an adaptive flow control method, device, computing device and storage medium. Background technique [0002] At present, the core network of 5G independent networking (SA) adopts interworking gateway equipment (InterWorking Function, IWF), which is responsible for the authentication and authentication of 4G or non-independent networking (NSA) users when they access the SA network, and 4G / 5G signing Mapping and interoperability with the Evolved Packet Core (EPC) network, providing related functions such as unified data management (Unified Data Manager, UDM) and authentication service (Authentication Server Function, AUSF) under the 5G core network, according to the existing technology In the networking scheme for IWF network elements, each province in a large region usually shares a set of IWF network elements. However, under this networking scheme, if a signaling sto...

Problems solved by technology

However, under this networking scheme, if a signaling storm occurs, how to protect the IWF network elements and avoid the impact on the business of each province in the region is an urgent problem to be solved

In the existing technology, all kinds of core network elements also have flow control mechanisms for network element self-protection, but their self-protection activation mechanisms are all of the “remedial” type, that is, flow control is implemented only after network elements have been impacted, and some Messages are not processed, and when flow control is implemented, adaptive adjustments cannot be made for all directions, which will inevitably affect the normal business use of other provinces in the same region
