Dynamic Connection Parameter Authorization in Communication Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication networks face challenges in dynamically managing and controlling connection parameters, especially when dealing with different types of networks and services, leading to suboptimal QoS and charging issues across various communication connections.
Innovation Solution
A method and system that involve a communication control mechanism where a third network element requests authorization for connection parameters from a fourth network element, which decides on authorized parameters and service types, and sends a decision message including authorization and further authorization control information, enabling dynamic QoS and charging management across different service types and networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If dynamic authorization for connection parameters is implemented across different network types and service types, then network resource utilization and QoS management are improved, but signaling load and system complexity increase
Solution Approach 1:
The system segments authorization control by introducing service-type-specific indication information that divides the authorization process into network-level parameters and service-level parameters. This allows different authorization granularities for different service types without requiring complete reauthorization for every parameter change, thus improving resource utilization while managing complexity through structured segmentation.
Solution Approach 2:
The patent adds a new dimension to the authorization system by introducing service type as an additional classification layer beyond network type. This multi-dimensional approach (network type × service type) enables more precise control and optimization of authorization processes, allowing the system to handle diverse service requirements without linearly increasing overall system complexity.
2Measurement precision
If service-type-specific authorization control is implemented, then charging policies and QoS management are optimized, but signaling load increases
Solution Approach 1:
The system applies partial action by implementing service-type-specific authorization only where needed rather than universally for all services. The indication information selectively triggers detailed service-level authorization control only for services that require it, while allowing simpler network-level authorization for other services, thus optimizing charging precision without generating excessive signaling for all service types.
3Adaptability or versatility
If multiple network elements are involved in authorization decisions, then authorization flexibility is improved, but coordination overhead and signaling load increase
Solution Approach 1:
The system performs preliminary action by pre-establishing service-type-specific authorization rules and indication information in advance. When authorization requests are made, the pre-configured service type indications enable faster decision-making by multiple network elements, as the framework for authorization flexibility is already in place, reducing real-time coordination overhead while maintaining adaptability.
Data Source
AI summary
A mechanism for controlling connection parameters for a communication connection between network elements is disclosed. When the communication connection is initialized, an authorization for the connection parameters of services is requested from a policy control entity which decides on connection parameters to be authorized for the communication connection and on service types which can be provided for the communication connection. A decision message is sent to a communication control network element wherein the decision message comprises the authorization for the connection parameters, service types usable for the communication connection, and an information portion indicating, for each service, whether or not the policy control entity controls a further authorization regarding at least one of the indicated service types in the communication connection. The decision message is enforced in the communication connection by the communication control network element.
