Abstract

Various embodiments of the present technology generally relate to systems and methods for providing a subscription resource engine to suppress transmission of event notifications to originating network functions (NFs). For example, a subscription resource engine may detect an event operation associated with a consumer NF within a network. The consumer NF may be subscribed to a producer NF such that the subscription allows the consumer NF to receive event notifications from the producer NF. The subscription resource engine may determine that the event operation is related to the subscription and generate a subscription resource header based on the subscription. Based on the subscription resource header, the subscription resource engine may then generate an indication to suppress transmission of an event notification to the consumer NF. The indication to suppress transmission of the event notification may cause the producer NF to skip transmission of the event notification to the consumer NF.

Description

TECHNICAL FIELD Various embodiments of the present technology generally relate to network function communication within networks. More specifically, embodiments of the present technology relate to systems and methods for providing a subscription resource engine for suppressing transmissions of notifications to originating network functions within a network. BACKGROUND Communication networks, such as 4G and 5G, have become the backbone of modern communication, revolutionizing how people and devices connect across the globe. These technologies provide the essential infrastructure for high-speed, reliable wireless communication, enabling everything from everyday smartphone use to complex industrial applications. 4G networks laid the foundation by introducing fast data transfer rates and improved mobile internet experiences. Now, with the advent of 5G, the world is witnessing unprecedented advancements in speed, capacity, and low-latency communication, paving the way for transformative applications like autonomous vehicles, smart cities, and the Internet of Things (IoT). These networks collectively form the cornerstone of modern communication, driving innovation and shaping the future of global connectivity. Within communication networks, such as 4G and 5G, network functions often subscribe to each other to ensure efficient and coordinated service delivery. A subscription in this context involves one network function registering its interest in receiving specific data or events from another network function. For example, a user authentication function might subscribe to notifications from a location service to track user mobility across different network cells. Subscriptions typically include details such as the type of data or events requested, conditions for triggering notifications, and the duration of the subscription. This dynamic interaction allows network functions to communicate seamlessly, facilitating tasks such as load balancing, service orchestration, and policy enforcement. These interdependencies are key to ensuring the reliability, scalability, and adaptability of modern communication networks, particularly as they manage complex services like IoT devices and real-time multimedia applications. One issue with conventional subscription frameworks within communication networks, such as a 5G network, is that the consumer network function (NF) that subscribes to a producer NF is sometimes the very source of the change it is monitoring. For example, when a consumer NF initiates an operation like creating or deleting a resource, it may still receive a notification of this change from the producer NF, even though it originated the action. This redundant notification leads to inefficient processing and unnecessary signaling overhead, as the consumer NF is alerted to information it already possesses. In large-scale networks where multiple NFs interact, this can result in excessive signaling traffic, wasted computational resources, and degraded network performance, including slower response times and reduced capacity to handle other critical tasks. Accordingly, there exists a need for systems and techniques for improved subscription frameworks within communication networks. In particular, there is a need for a subscription resource engine that monitors operational events within a subscription between a consumer NF and producer NF to identify scenarios when the triggering event is from a particular consumer NF. As will be described in greater detail below, when the subscription resource engine identifies a notification that is triggered by an originating consumer NF, the subscription resource engine may cause the producer NF to suppress transmission of the notification to the originating consumer NF. The information provided in this section is presented as background information and serves only to assist in any understanding of the present disclosure. No determination has been made and no assertion is made as to whether any of the above might be applicable as prior art with regard to the present disclosure. OVERVIEW Technology is disclosed herein for systems and techniques for providing a subscription resource engine and one or more of its related functions. As described in greater detail below, the subscription resource engine may determine an event operation associated with a consumer NF within a network. In particular, the subscription resource engine may determine when an event operation is associated with a subscription between a consumer NF and a producer NF within a communication network. Under the subscription, the consumer NF may be a subscribed NF such to receive event notifications from the producer NF regarding specific resources or objects that are relevant to the consumer NF. In some embodiments when an event operation is detected, a consumer-side subscription resource engine may generate a subscription resource header based on the subscription between the consumer NF and the producer NF.
