Network Element Resource Reservation for Mobile QoS
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication networks lack the ability to accurately reserve resources based on the specific Quality of Service (QoS) requirements for upload and download directions, leading to inefficient resource allocation and potential suboptimal service quality for applications.
Innovation Solution
A method where a network element determines the type of application requesting a communication connection, estimates the required QoS, and reserves resources accordingly, allowing for dynamic allocation and management of resources to meet the specific needs of different applications, thereby optimizing resource usage and ensuring better service quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If resources are reserved based on default bearer with best effort service, then network operation is simple, but service quality and transmission speed cannot be guaranteed
Solution Approach 1:
The patent segments resource reservation by creating dedicated bearers for specific applications with guaranteed bit rates, separating them from default best-effort bearers. This allows critical applications to have reserved resources while maintaining simple best-effort service for other traffic, thus improving service quality for specific applications without entirely complicating network operation.
Solution Approach 2:
The patent enables dynamic creation and management of dedicated bearers based on application requirements. The network can dynamically allocate resources when needed (when applications require guaranteed service) and release them when not needed, making the system adaptable without permanent complexity.
2Reliability
If GBR is specified for dedicated bearer, then transmission resources are reserved and blocked by admission control, but multiple applications sharing a dedicated bearer cannot guarantee that every application can use the GBR
Solution Approach 1:
The patent segments the dedicated bearer resources by introducing application-specific parameters and enabling the network to allocate portions of the GBR to different applications based on their individual requirements. This allows multiple applications to share a dedicated bearer while each receives appropriate resource guarantees through refined admission control that considers per-application needs.
Solution Approach 2:
The patent applies local quality by allowing different QoS parameters and resource allocations for different applications within the same dedicated bearer. Each application can have tailored resource reservations and admission control settings, enabling precise control over which applications receive guaranteed bit rates and at what levels.
3Ease of manufacture
If QCI is assigned to bearer, then traffic handling is standardized, but the same QCI is assigned for both uplink and downlink even when applications require different QoS characteristics for one direction
Solution Approach 1:
The patent segments the QoS configuration by introducing separate QoS parameter settings for uplink and downlink directions. While maintaining the standardized QCI framework for ease of configuration, the system now allows different QoS characteristics to be applied to each direction, enabling precise matching of application requirements without sacrificing configuration simplicity.
Solution Approach 2:
The patent applies local quality by allowing direction-specific QoS optimization. Each bearer can have customized uplink and downlink parameters based on application needs (e.g., voice traffic requiring guaranteed downlink but flexible uplink), while still utilizing the standardized QCI classification system for manageable configuration complexity.
4Productivity
If resources are allocated without considering application type, then resource allocation is simple, but resource allocation does not match actual QoS demands leading to inefficient resource usage
Solution Approach 1:
The patent implements preliminary action by requiring applications to declare their QoS requirements and types in advance during bearer setup. The network performs admission control based on these pre-declared requirements, allocating resources that match actual application needs before traffic begins. This prevents both over-provisioning and under-provisioning, improving resource allocation efficiency without requiring complex real-time adjustments.
Solution Approach 2:
The patent introduces feedback mechanisms where the network monitors actual traffic patterns and QoS requirements, and adjusts resource allocation accordingly. Admission control decisions are informed by feedback about application performance and network conditions, enabling efficient resource matching while maintaining manageable complexity through automated adjustment rather than manual configuration.
