MME Feature Announcement for Data-Centric UE Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for an efficient method to connect User Equipment (UE) to a Mobility Management Entity (MME) that supports specific supplementary functions in wireless communication systems, particularly for data-centric communication, as existing systems lack an effective mechanism for UE to identify and connect to MMEs with the necessary features.
Innovation Solution
The proposed solution involves a wireless communication system and method that enables UE to efficiently connect to an MME supporting the intended supplementary functions by using signal flow diagrams and flowcharts to manage attachments and feature notifications, ensuring the UE can perform data-centric communication efficiently by identifying and selecting MMEs with the required features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the UE connects to any MME in the network, then the connection establishment is simple and fast, but the UE cannot access supplementary functions that require specific MME features
Solution Approach 1:
The MME publicly announces its supported supplementary functions and features in advance through system information blocks (SIB) or other signaling mechanisms before the UE attempts to connect. This allows the UE to identify compatible MMEs beforehand, ensuring both adaptability to supplementary functions and efficient connection establishment without trial-and-error attempts.
Solution Approach 2:
The system implements a feedback mechanism where the MME communicates its capability information to the UE, and the UE uses this information to select an appropriate MME. This bidirectional information exchange ensures that the UE can access required supplementary functions while maintaining simple and efficient connection procedures.
2Adaptability or versatility
If the UE attempts to connect to multiple MMEs to find one supporting the required supplementary function, then the adaptability to supplementary functions is improved, but the connection establishment time increases
Solution Approach 1:
The MME publishes its supported supplementary functions in advance through broadcasting or dedicated signaling before the UE connection attempt. This preliminary announcement allows the UE to identify a compatible MME in a single attempt, eliminating the need to try multiple MMEs and significantly reducing connection establishment time while maintaining full adaptability to supplementary functions.
3Adaptability or versatility
If the network uses a centralized MME for all UEs, then the network structure is simple, but UEs requiring specific supplementary functions cannot connect to MMEs with the required features
Solution Approach 1:
The network is segmented into multiple MMEs, each specializing in specific supplementary functions or feature sets. This segmentation allows different UEs with different requirements to be served by appropriately specialized MMEs, achieving both feature-specific access and manageable network complexity through functional decomposition.
Solution Approach 2:
Different MMEs are assigned different supplementary function capabilities based on local requirements and network deployment needs. This local quality approach allows the network to provide feature-specific MME access without requiring a completely complex centralized structure, as each MME can be independently configured with specific capabilities.
