Binding Indication Structure for Direct Network Function Notifications
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication networks lack efficient mechanisms for direct notifications between network functions, leading to increased signaling load and complexity in network function interactions.
Innovation Solution
The solution involves complementing binding indications with identification of the intended user and resource owner, enabling direct notifications by including this information in application payloads or headers like 3gpp-Sbi-Binding, and associating binding resources with subscription information using Uniform Resource Identifiers (URIs).

1Productivity
If binding indication is included in requests and responses without identification of intended user and resource owner, then the binding mechanism is simple, but direct notifications between network functions cannot be enabled and signaling load increases
Solution Approach 1:
The binding information is segmented into distinct components: binding indication, intended user identification, and resource owner identification. This segmentation allows each component to serve its specific function while maintaining overall system efficiency. The binding indication handles routing, the intended user field identifies the notification sender, and the resource owner field identifies the target, enabling direct notifications without increasing overall complexity.
Solution Approach 2:
The identification information (intended user and resource owner) is nested within the binding indication structure. This nesting allows the additional information to be carried efficiently within existing message formats without requiring separate signaling exchanges, thus enabling direct notifications while minimizing the increase in information structure complexity.
2Adaptability or versatility
If binding information is transmitted without correlation mechanism, then transmission is straightforward, but association between binding resource and subscription information fails when multiple bindings are included
Solution Approach 1:
A correlation mechanism provides feedback between binding information and subscription information. When multiple bindings are included in a request, the correlation mechanism enables the receiving network function to correctly associate each binding with its corresponding subscription, ensuring proper routing and notification delivery while supporting versatile multi-binding scenarios.
3Loss of energy
If traditional binding mechanism is used without intended user and resource owner identification, then message format remains simple, but signaling load increases and direct notifications are not enabled
Solution Approach 1:
The intended user and resource owner identifications are included preliminarily in the binding indication at the time of subscription or request. This preliminary inclusion eliminates the need for subsequent signaling exchanges to establish these relationships, thereby reducing overall signaling load while the additional information content is managed efficiently within the initial message structure.

AI summary
A method for binding indication is provided. The method is implemented by a first network function in a communication network. The method may comprise generating a first binding information for a first notification endpoint in a network function, the first binding information indicating a first intended user of the first binding information and a first resource owner of the first notification endpoint. The method may further comprise sending the first binding information to a second network function.
