Virtual User-Specific Connectivity Manager for Dynamic Mobility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network architectures lack flexibility in adapting to dynamic radio access network topology changes and cannot provide customized mobility management for individual user equipment (UE), relying on fixed-location mobility management entities (MMEs) and service gateways (SGWs) that are not UE-specific.
Innovation Solution
The implementation of virtual user-specific connectivity managers (v-u-CM) and virtual user-specific service gateways (v-u-SGW) that are dynamically created and relocated based on UE registration and location, allowing for customized data plane network topology and mobility management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed-location MMEs and SGWs are used, then network architecture is simple and stable, but flexibility to adapt to dynamic RAN topology changes is poor
Solution Approach 1:
The patent implements dynamic MME and SGW selection based on UE mobility patterns and service flow characteristics. The network controller dynamically determines optimal MME/SGW locations and configurations rather than using fixed assignments, allowing the system to adapt to changing RAN topology while maintaining manageable complexity through automated control
2Adaptability or versatility
If fixed-location MMEs are selected by geography, then MME selection is simple, but customized mobility management for individual UE cannot be provided
Solution Approach 1:
The patent applies different MME selection criteria to different UE types, service flows, and mobility scenarios. Each UE receives customized mobility management based on its specific characteristics (e.g., mobility pattern, service requirements) rather than uniform geographic assignment, enabling personalized management while the network controller manages the complexity of multiple selection policies
3Reliability
If traditional MMEs are used, then network operation is stable, but ability to track and respond to UE location dynamically is limited
Solution Approach 1:
The patent implements location tracking and MME/SGW pre-configuration based on predicted UE mobility patterns. The network controller proactively prepares appropriate MME/SGW assignments before UE movement occurs, ensuring reliable handover while improving tracking efficiency through advance planning rather than reactive responses

AI summary
A method embodiment includes configuring, by a virtual user-specific connectivity manager (v-u-CM) on a processor, a location estimation scheme for a user equipment (UE) in accordance with UE configuration. The v-u-CM is created in accordance with registration of the UE in the network. The method further includes tracking, a location of the UE in accordance with the location estimation scheme.
