Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless networks with overlapping coverage areas, the existing admission in connected mode mechanisms lead to excessive access to LTE networks, causing overload and decreased communication quality due to preferential camping by multimode terminals.
Innovation Solution
A method and system where a wireless network device determines the throughput rate for a multimode terminal in multiple networks and sends it to a decision device, which determines the most suitable network for access based on SINR, resource block utilization, and load status for LTE, and CQI estimation and idle codes for UMTS, optimizing network resource configuration and reducing network load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If preferential admission to LTE network is implemented, then access efficiency for multimode terminals is improved, but network overload occurs and communication quality deteriorates
Solution Approach 1:
The patent changes the admission decision parameter from network preference (LTE-first policy) to throughput rate comparison. The decision device calculates throughput rates for both LTE and UMTS networks using specific formulas (Equation 1 for LTE, Equation 2 for UMTS) and selects the network with higher throughput, thereby resolving the contradiction between access efficiency and communication quality
Solution Approach 2:
The patent implements feedback mechanisms where network devices continuously monitor and report load status parameters (LTE load status, UMTS load status) to the decision device. This feedback enables dynamic adjustment of admission decisions based on real-time network conditions, preventing overload while maintaining efficient access
2Speed
If preferential camping on LTE is allowed, then terminal access speed is improved, but network load becomes excessive
Solution Approach 1:
The patent introduces dynamic network selection where the preferred network can switch between LTE and UMTS based on real-time throughput rate calculations and load conditions. The system dynamically adjusts admission decisions by comparing current network states, enabling fast access when LTE is underutilized while redistributing load when LTE becomes congested
Solution Approach 2:
The decision device acts as an intermediary between multimode terminals and network devices. It receives throughput rate information and load status from both LTE and UMTS networks, performs centralized evaluation, and makes balanced admission decisions that prevent excessive load on any single network while maintaining rapid access
