5G Network Element Registration with Shared Data Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G network architectures, the registration of network elements with a network repository function (NRF) results in significant bandwidth and signaling overheads due to large amounts of network element parameter information being transmitted.
Innovation Solution
A communication method where network elements send identifier information of shared data instead of the shared data itself during registration, with the network repository storing only one copy of the shared data and subscribing to updates as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If network element parameter information including shared data is transmitted during registration, then complete information is provided, but bandwidth resource overheads and signaling overheads increase
Solution Approach 1:
The network element parameter information is segmented into two parts: NFprofile (network element specific parameters) and sharedData (common parameters). The NFprofile is transmitted during registration, while the sharedData is managed separately through subscription mechanisms, reducing the amount of data transmitted during registration.
Solution Approach 2:
The shared data is extracted from the network element parameter information and managed independently. Instead of including shared data in each registration message, the system extracts it as a separate entity that can be subscribed to and updated independently, reducing redundancy in communication.
2Reliability
If each network element stores its own copy of shared data, then data availability is improved, but storage resource occupation increases
Solution Approach 1:
Multiple network elements share a common data repository for shared data instead of each maintaining separate copies. The NRF (Network Repository Function) acts as a central repository that stores shared data once and provides it to multiple NFs (Network Functions) that subscribe to it, reducing total storage occupation while maintaining availability.
Solution Approach 2:
The shared data repository serves multiple network elements simultaneously. A single storage location in the NRF provides data to multiple NFs that have subscribed to the same shared data, making the storage system universal and multi-functional rather than dedicated to each individual NF.
3Quantity of substance
If shared data is stored centrally in the network repository, then storage efficiency is improved, but data freshness may be compromised
Solution Approach 1:
The system implements a subscription-based feedback mechanism where NFs that need shared data subscribe to updates. When shared data changes, the NRF automatically notifies and pushes updated data to all subscribed NFs, ensuring data freshness is maintained through continuous feedback loops rather than periodic polling or manual updates.
Solution Approach 2:
Network elements subscribe to shared data in advance before they need it. This preliminary subscription action enables the system to proactively push updates when data changes, rather than waiting for NFs to request updates, ensuring data freshness is maintained through advance preparation.

AI summary
A communication system, device and method, the method including receiving, by a network repository network element, a network element registration request from a first network element, where the network element registration request includes network element parameter information of the first network element, the network element parameter information includes identifier information of shared data and identifier information of the first network element, and the network element parameter information is free of the shared data corresponding to the identifier information of the shared data, and storing, by the network repository network element, the network element parameter information.
