Description

Background Art

[0002] With the development of the times, the number of wireless network users is gradually increasing. In wireless networks, the Charging Function (CHF) network element is an indispensable module. Once the CHF network element is overloaded, the Session Management Function (SMF) network element releases a large number of user sessions, triggering network-side service flow control. After the subsequent process is flow controlled, the terminal needs to re-initiate the initial registration process and restart. At the same time, the failure of the terminal registration process will trigger repeated registrations.

[0053] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that the disclosure will be more comprehensive and complete and to fully convey the concepts of the example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0054] In addition, the accompanying drawings are only schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the figures represent the same or similar parts, and their repeated description will be omitted. Some of the block diagrams shown in the accompanying drawings are functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities can be implemented in software form, or implemented in one or more hardware modules or integrated circuits, or implemented in different networks and / or processor devices and / or microcontroller devices.

[0055] It should be understood that the various steps described in the method embodiments of the present disclosure may be performed in different orders and / or in parallel. In addition, the method embodiments may include additional steps and / or omit the steps shown. The scope of the present disclosure is not limited in this respect.

[0056] It should be noted that the concepts such as "first" and "second" mentioned in the present disclosure are only used to distinguish different devices, modules or units, and are not used to limit the order or interdependence of the functions performed by these devices, modules or units.

[0057] It should be noted that the modifications of "one" and "plurality" mentioned in the present disclosure are illustrative rather than restrictive, and those skilled in the art should understand that unless otherwise clearly indicated in the context, it should be understood as "one or more".

[0058] The CHF network element plays an indispensable role in the user session creation process. Once the CHF network element of the current 5GSA core network is overloaded, the Session Management Function (SMF) network element releases a large number of user sessions, resulting in a large number of users initiating sessions concurrently, triggering network-side service flow control. After the subsequent process is flow controlled, the terminal needs to re-initiate the initial registration process and restart. At the same time, the failure of the terminal registration process will trigger repeated registrations. The repeated superposition of various user signaling will trigger a signaling storm in the 5GC core network and IMS network, triggering a surge in signaling, causing the overloaded CHF to receive more signaling, resulting in network element failure, and in severe cases, causing the entire 5G mobile network to be paralyzed. Since the Access and Mobility Management Function (AMF) that performs service control on the number of user registration transactions does not have a process that directly interacts with the CHF, it cannot perceive the operating status and capability of the CHF, resulting in the inability to adjust the flow control value in real time to protect the CHF network element.
