Problems solved by technology

[0002] The "tidal effect" of the urban population and the irregular registration and access of a large number of IoT devices may cause the 5G network to be overloaded, which will have an impact on the core network access and mobility management function (Core Access and Mobility Management Function, AMF). Crashes, and AMF failures in 5GC may also cause overloading of other AMFs in the AMF set (denoted as AMFset), so in order to ensure the normal operation of 5GC, disaster recovery backup is required for AMF
[0003] The traditional disaster recovery backup method has the following disadvantages in the AMF disaster recovery backup of 5GC: Since AMFs in different AMFsets in 5GC may belong to different slice networks, it is necessary to back up an AMF that supports corresponding slices for all AMFs, which will greatly increase The cost of network deployment is increased, and the increase of a large number of backup AMFs also leads to an increase in energy consumption of 5GC, which increases the network operation cost of 5GC

Embodiment Construction

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0044] figure 1 It shows the network topology diagram of the AMF backup disaster recovery method in the prior art. In this figure, AMF_1 and AMF_2 are mutual backups. When AMF_1 or AMF_2 fails, the other AMF can ensure the normal operation of 5GC, and through the backup AMF and load balancing Reduce the pressure on AMF in 5GC to prevent the impact on 5GC when a large number of users use AMF services.

[0045] However, in this traditional AMF backup disast...

Abstract

The invention provides a method for backing up an AMF in a 5G core network. The core network comprises a network resource management function NRF, a first AMF set, a second AMF set and a universal AMFset. Any backup AMF in the universal AMF set supports the backup of the first AMF set or the second AMF set. The NRF carries out network resource management on the first AMF set, the second AMF set and the universal AMF set; the method comprises the following steps: the NRF determines that the first AMF set is overloaded; the NRF determines a kth backup AMF from the general AMF set and indicatesthe kth backup AMF to join in the first AMF set for service, and k is a positive integer smaller than or equal to S.

Description

technical field [0001] The present invention relates to the field of communications, and more specifically, to a method and system for backing up an AMF in a 5G core network. Background technique [0002] The "tidal effect" of the urban population and the irregular registration and access of a large number of IoT devices may cause the 5G network to be overloaded, which will have an impact on the core network access and mobility management function (Core Access and Mobility Management Function, AMF). Crashes and AMF failures in 5GC may also cause overloading of other AMFs in the AMF set (denoted as AMFset). Therefore, in order to ensure the normal operation of 5GC, disaster recovery backups are required for AMFs. [0003] The traditional disaster recovery backup method has the following disadvantages in the AMF disaster recovery backup of 5GC: Since AMFs in different AMFsets in 5GC may belong to different slice networks, it is necessary to back up an AMF that supports corresp...
