LTE MME Reselection by User Profile
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current user Mobility Management Entity (MME) selection in wireless communication networks is insufficient, as it lacks flexibility and does not allow for optimal assignment based on user-specific criteria such as requested services, quality of service, or user preferences.
Innovation Solution
A Long Term Evolution (LTE) communication system that performs MME reselection based on user profiles, which include service requirements and quality of service, allowing for dynamic assignment of MMEs to User Equipment (UE) during communication sessions, using databases like the Home Subscriber Server and Domain Name Server to facilitate this process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If current MME selection methods are used, then the system operates with simple selection algorithms, but the user service quality and flexibility are insufficient
Solution Approach 1:
The patent implements dynamic MME reselection by allowing the network to reassess and change the MME assignment for a UE based on current conditions such as service requirements and user profiles, rather than using static selection algorithms. This enables the system to adapt to changing user needs and network conditions, improving service quality while managing complexity through controlled dynamic adjustments.
Solution Approach 2:
The system changes selection parameters by considering multiple factors including user profiles, service requirements, and quality of service parameters when selecting or reselecting MMEs. This multi-parameter approach allows flexible and user-centric MME selection, moving beyond simple algorithms to a more sophisticated selection mechanism that balances adaptability with manageable complexity.
2Reliability
If MME reselection based on user profiles is implemented, then service quality matching is improved, but system complexity increases
Solution Approach 1:
The system performs preliminary actions by retrieving and analyzing user profiles and service requirements before making MME selection or reselection decisions. This advance preparation allows the system to make informed decisions that ensure service quality matching, while the preliminary retrieval of necessary information helps manage complexity by organizing data access in a structured manner.
Solution Approach 2:
The patent introduces intermediary elements such as user profiles and service requirement databases that mediate between the UE and the MME selection process. These intermediaries contain pre-processed information about user preferences and service needs, allowing the selection system to make reliable decisions without directly managing all the complexity of user-specific requirements, thus ensuring service quality while managing system complexity.

AI summary
A wireless communication system connects User Equipment (UE) to Mobility Management Entities (MMEs). The wireless communication system receives a connection message from the UE. The wireless communication system connects the UE to a first MME responsive to the connection message. The wireless communication system performs MME re-selection for the UE responsive to the connection message. The wireless communication system connects the UE to a second MME responsive to the MME re-selection.
