Mobility Management Node Segmentation for UE Type Services
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity and inefficiency of providing differentiated services to various types of subscribers in cellular networks, particularly when managed by MMEs, lead to operational challenges and reduced maintenance efficiency.
Innovation Solution
A mobility management method that identifies the type of user equipment (UE) through initial access messages and selects a corresponding mobility management node capable of providing the appropriate service, simplifying operations and improving efficiency by ensuring the selected node supports the UE type.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the MME provides services for all types of subscribers, then the service coverage is comprehensive, but the operation complexity increases and efficiency decreases
Solution Approach 1:
The patent segments the mobility management function by introducing type-specific mobility management nodes (type-MMEs) for different subscriber types. Each type-MME is dedicated to serving a specific subscriber type, dividing the monolithic MME functionality into specialized segments. This segmentation reduces operation complexity within each node while maintaining comprehensive service coverage across all subscriber types through the collective capability of multiple specialized nodes.
2Adaptability or versatility
If the MME provides services for all types of subscribers, then the service coverage is comprehensive, but the service efficiency decreases
Solution Approach 1:
By segmenting the MME into type-specific instances, each node can be optimized for its dedicated subscriber type, improving processing efficiency through specialization. The segmentation enables parallel processing of different subscriber types across multiple nodes, increasing overall service throughput while maintaining comprehensive coverage.
Solution Approach 2:
The patent applies local quality by configuring each type-MME with subscriber type-specific parameters, capabilities, and service profiles. Each mobility management node is locally optimized for its designated subscriber type, enabling more efficient service delivery tailored to specific subscriber requirements rather than using a generic one-size-fits-all approach.
3Adaptability or versatility
If the MME provides services for all types of subscribers, then the service coverage is comprehensive, but the maintenance difficulty increases
Solution Approach 1:
Segmenting the mobility management functionality into separate type-specific nodes isolates maintenance tasks to individual specialized nodes. This segmentation allows maintenance personnel to work on one type-MME at a time without affecting other subscriber types, reducing the complexity and risk of maintenance operations while preserving comprehensive service coverage through the distributed architecture.

AI summary
Embodiments of the present invention provide a mobility management method, device, and system, which relate to the field of communications technologies. The method includes: receiving an initial user equipment UE access message; acquiring a type of UE according to the initial UE access message; selecting, according to the type, a first mobility management node that can provide a service for the UE of the type; and instructing the first mobility management node to provide a service for the UE. In the present invention, because a mobility management node provides a service by differentiating a type of user equipment, a mobility management node that can support a type of UE is selected to provide a service for the UE, which not only simplifies an operation procedure of the mobility management node and improves service efficiency, but also helps the mobility management node better manage and maintain the UE.
