Wireless QoS Management via Independent RAN and Core Network Parameters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current packet-switching wireless networks face inefficiencies in quality of service management due to per-connection agreements instead of per-service flow, lack of shared understanding between core and radio networks, complex parameter negotiations, excessive signaling, and inability to compare quality of service across network nodes, leading to complex and inefficient service setup and changes.
Innovation Solution
The method introduces a simplified quality of service management by using radio and core network-specific parameters (RFI, TCL, CFI) that allow independent adjustments without additional signaling, enabling quicker connection setup and service differentiation through packet filters and TCL values, which are unique to each user equipment, reducing the complexity and resource requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If per-connection quality of service agreements are used, then connection setup can be established, but service flow differentiation and efficiency are compromised
Solution Approach 1:
The patent segments the quality of service management from the connection setup phase and applies it at the service flow level. By introducing service flow identifiers and separate quality of service profiles, the system can differentiate services independently from connection establishment, allowing multiple services to share connections while maintaining individual quality guarantees.
Solution Approach 2:
The patent introduces a quality of service manager as an intermediary component that operates independently from the connection setup mechanism. This mediator handles quality of service assignments at the service flow level, decoupling the complexity of quality management from the connection establishment process and enabling more efficient service differentiation.
2Adaptability or versatility
If independent CN and RAN functions are used, then network flexibility is improved, but shared understanding of quality of service properties is lost
Solution Approach 1:
The patent introduces universal quality of service parameters and profiles that serve both the core network and radio access network. By defining standardized quality of service characteristics that are recognized across both domains, the system maintains shared understanding while preserving the independent operational flexibility of CN and RAN functions.
3Manufacturing precision
If multiple technical parameters are negotiated, then quality of service precision is improved, but signaling complexity increases
Solution Approach 1:
The patent changes the approach from negotiating multiple detailed technical parameters to assigning pre-defined quality of service profiles. By using standardized profiles with predetermined parameter sets, the system maintains the necessary precision for quality of service while dramatically reducing the signaling complexity associated with parameter negotiation.
4Reliability
If extensive signaling is used for connection setup, then quality of service configuration is complete, but connection establishment time increases
Solution Approach 1:
The patent performs quality of service configuration actions in advance by pre-defining quality of service profiles and parameters. This preliminary preparation allows the connection setup process to simply reference and apply appropriate profiles rather than negotiating and configuring each parameter in real-time, significantly reducing setup time while maintaining configuration completeness.
Data Source
AI summary
A method for guaranteeing the quality of services in packet-switching radio communications networks. The radio access network (RAN) and the core network (CN) use the quality of service information independently of one another, without signalling individual parameters, in order to guarantee the transmission of packets in the uplink and downlink according to the quality of service. This is achieved exclusively using local settings that have been configured for individual TCLs, permitting a radical reduction in complexity compared to conventional methods. The method is further simplified by the described interlinking of different tasks or the linking of such tasks to an existing data transmission.
