Network Redirection in Heterogeneous Overlay Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
User equipment in heterogeneous overlay networks, such as LTE and WCDMA, often experiences poor signal reception due to network load and location issues, necessitating efficient redirection between networks to optimize service quality.
Innovation Solution
A method for redirecting user equipment between heterogeneous overlay networks based on predetermined network access priorities, network load, and accounting information, involving a mobility management entity to determine necessary network redirection and transmit relevant information to the user equipment via a radio resource control connection release message.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If user equipment is redirected between heterogeneous networks, then network load distribution is improved, but redirection complexity and processing time increase
Solution Approach 1:
The patent applies preliminary action by pre-configuring network access priorities and user preferences in the mobility management entity before redirection is needed. The system pre-establishes the criteria for network selection based on user profiles and network conditions, so that when redirection is required, the decision process is simplified and faster, reducing the complexity burden during actual redirection operations.
Solution Approach 2:
The patent implements feedback mechanisms where the mobility management entity continuously monitors network conditions and user status, adjusting redirection decisions based on real-time information. This feedback loop optimizes load distribution by responding to actual network state changes, improving productivity while managing complexity through adaptive rather than static redirection rules.
2Reliability
If user equipment is redirected based on network access priority, then service quality is improved, but redirection decision time increases
Solution Approach 1:
The system pre-determines network access priorities and user preferences before redirection is needed, storing this information in the mobility management entity. When redirection is required, the system simply needs to retrieve and apply the pre-configured priorities rather than evaluating multiple criteria in real-time, significantly reducing decision time while maintaining service quality based on user-specific preferences.
Solution Approach 2:
The patent changes the parameter of network selection from dynamic multi-criteria evaluation to static priority-based selection. By transforming the redirection decision into a lookup operation based on pre-established priority parameters, the system achieves fast decision-making without compromising service quality, as the priorities are configured to reflect actual service requirements.
3Productivity
If heterogeneous overlay networks are used, then network capacity is improved, but network management complexity increases
Solution Approach 1:
The mobility management entity serves multiple functions: it manages user authentication, tracks user preferences, monitors network conditions, and executes redirection decisions. By consolidating these functions into a single multi-functional entity, the patent reduces the overall network management complexity despite using heterogeneous overlay networks, while still achieving improved network capacity through coordinated redirection operations.
Solution Approach 2:
The mobility management entity acts as an intermediary between user equipment and the heterogeneous overlay networks. It centralizes the redirection logic and coordinates communication between different network types, simplifying network management by providing a single point of control that handles all redirection operations uniformly, regardless of the specific network combination involved.
