Network Element Selector Group-Based Controller Assignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The 3GPP SAE core network architecture has excessive control network elements and status information distribution, leading to inefficient communication due to high complexity in controller selection and signaling processing, particularly when selecting controllers on a per-UE basis.
Innovation Solution
A network element selector (NES) determines a controller based on user groups rather than individual user equipment (UE), reducing the complexity of controller selection and improving signaling processing efficiency by using a preset correspondence between user groups and controllers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a controller is selected on a per-UE basis, then each user equipment can be served individually, but the complexity of controller selection increases and signaling processing efficiency decreases
Solution Approach 1:
The patent merges multiple individual UE controller selections into a single user group-level controller selection. Instead of selecting a controller for each UE individually, the system selects one controller per user group, thereby reducing selection complexity while maintaining group-based service capability.
Solution Approach 2:
The user group controller serves multiple UEs within its group simultaneously, performing multi-functionality. This universal approach allows a single controller to handle signaling for multiple users, reducing the total number of controllers needed and simplifying the selection process.
2Productivity
If a controller is selected on a per-UE basis, then individual signaling can be processed, but the signaling processing efficiency of the system decreases
Solution Approach 1:
The patent combines multiple individual signaling processing tasks into a single group-level processing operation. By selecting one controller per user group rather than per UE, the system reduces the number of signaling interactions required, thereby improving signaling processing efficiency.
Solution Approach 2:
The system performs preliminary grouping of UEs into user groups before controller selection. This preliminary organization allows for more efficient subsequent signaling processing, as controllers are selected once per group rather than repeatedly for each individual UE.
3Reliability
If excessive control network elements are used, then detailed control can be performed, but the overall communication efficiency of the system reduces
Solution Approach 1:
The patent merges the control functions of multiple individual controllers into a single user group controller. This consolidation maintains the necessary control capabilities for detailed user management while reducing the total number of control network elements, thereby improving communication efficiency.
Solution Approach 2:
The user group controller performs multiple control functions that would otherwise require separate individual controllers. This multi-functional design maintains comprehensive control capability while using fewer network elements, improving system efficiency.

AI summary
Embodiments of this application provide an information transmission method, a network element selector, and a controller. The information transmission method provided in the embodiments of this application includes: receiving, by an NES from an external network element, a first message including identification information of UE; determining, based on the identification information of the UE, a user group to which the UE belongs; determining a controller corresponding to the user group; and then sending the first message to the controller. According to the embodiments of this application, complexity of selecting a controller can be reduced, and signaling processing efficiency can be improved.
