Centralized RIM Server for LTE Load Balancing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless networks, such as LTE, lack a centralized and unified solution for efficiently and intelligently allocating radio resources across multiple radio access technologies, leading to inadequate capacity management and quality of service (QoS) provision, especially for large service providers with diverse radio access technologies.
Innovation Solution
A method involving a server in the LTE network that monitors and manages radio access technologies (RATs) by receiving utilization data and proactively switches user devices to less congested RATs, using new logical interfaces and Radio Information Management (RIM) approaches to minimize service interruptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a decentralized radio resource management approach is used in current LTE networks, then user equipment can independently select radio access technologies based on basic capability, but centralized and intelligent allocation of radio resources across multiple radio access technologies is lacking
Solution Approach 1:
The patent introduces a centralized Radio Information Management (RIM) server as an intermediary between user equipment and multiple radio access technologies. This server collects utilization information from different RATs (2G, 3G, 4G, WiFi, WiMAX) and makes intelligent load balancing decisions, thereby achieving centralized and intelligent radio resource allocation without requiring complex decentralized decision-making at each network element.
Solution Approach 2:
The RIM server provides a universal platform that manages multiple radio access technologies simultaneously. It handles load balancing, utilization monitoring, and migration decisions across diverse RATs (2G, 3G, 4G, WiFi, WiMAX) through a single centralized system, enabling one solution to serve multiple technology standards.
2Productivity
If radio resources are allocated without centralized management, then network operation is simpler, but dynamic capacity management and quality of service provision across multiple radio access technologies is inadequate
Solution Approach 1:
The system implements continuous feedback loops where the RIM server monitors utilization information from multiple RATs in real-time, analyzes the current network state, and dynamically adjusts load balancing decisions. This feedback mechanism enables proactive load balancing by detecting adverse network conditions and triggering user device migrations before service degradation occurs.
Solution Approach 2:
The RIM server performs preliminary analysis of utilization information to predict potential network congestion or adverse conditions. By detecting trends in advance and proactively initiating load balancing actions before actual service degradation occurs, the system prevents problems rather than merely reacting to them.
3Reliability
If user devices migrate between radio access technologies without proactive management, then network flexibility is maintained, but service interruptions and quality of service degradation occur during load balancing
Solution Approach 1:
The RIM server acts as an intelligent intermediary that coordinates migrations between RATs. It receives utilization information, makes informed decisions about necessary migrations, and manages the transition process to minimize service interruptions, thereby enabling automated load balancing while maintaining service continuity.
Data Source
AI summary
A method may comprise receiving, at a server configured in a long term evolution network, information indicative of a condition of utilization of a first radio access technology resource accessible by a user device. If the condition of utilization indicates an adverse network condition, then the server may transmit a change command instructing the user device to migrate to a second radio access technology resource.
