IMS Core 5G Data Identification via Modified PANI Header
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In networks with both LTE and 5G base stations, 5G-capable devices are not accurately identified by the IMS core, leading to 'blind spots' where 5G communication data is not distinguished from 4G or 4G LTE data, making it difficult for network operators to monitor and troubleshoot 5G services effectively.
Innovation Solution
During device registration, a modified P-Access-Network-Information (PANI) header is used to notify the IMS core that the device is 5G-capable, allowing it to label and store communication data as 5G data rather than 4G or 4G LTE data, enabling easier monitoring and optimization of 5G services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If 5G-capable devices register on LTE base station first (master/secondary relationship), then device can access both LTE and 5G networks, but IMS core cannot identify device as 5G-capable creating blind spots for monitoring
Solution Approach 1:
The device performs preliminary registration on the LTE base station before registering on the 5G base station. This preliminary action establishes the master/secondary relationship and ensures the device can access both networks, while the subsequent modification of PANI header during IMS core registration preserves the 5G capability information
Solution Approach 2:
The modified PANI header acts as an intermediary carrier that transmits 5G capability information from the device to the IMS core. By embedding the 5G radio access technology indicator in this header, the system bridges the gap between the device's 5G capability and the IMS core's need for identification
2Device complexity
If 5G communication data is stored same as 4G data, then network operations are simplified, but network operators cannot monitor or troubleshoot 5G services effectively
Solution Approach 1:
The system applies local quality by differentiating the storage or labeling of 5G communication data from 4G data. By using the 5G capability identification from the modified PANI header, the network can apply different quality attributes, monitoring rules, or storage procedures specifically to 5G data while maintaining simplicity for other data
3Adaptability or versatility
If multiple network types (3G, 4G, LTE, 5G) operate in same area, then service coverage and compatibility are improved, but network data becomes difficult to categorize and manage
Solution Approach 1:
The system uses the modified PANI header as a form of 'color coding' for network data. By embedding the 5G radio access technology indicator, each network type (3G, 4G, LTE, 5G) can be visually or programmatically distinguished, allowing network operators to easily categorize and manage data from different network types through filtering or routing based on this identifier

AI summary
Systems and methods for categorizing communication data are described herein. The systems and methods enable an IMS core network to register a user equipment as a 5G-capable device and store communication data in a manner that differentiates the communication data from non-5G devices. Once identified as a 5G-capable device and information that 5G coverage is available is received, the registration message from the user equipment to the IMS core is modified to configure the IMS core to store the communication data as 5G communication data rather than non-5G communication data.
