RNC Classifier for QoS Bearer Establishment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 3GPP architecture lacks the ability to prioritize RNC functionalities using existing QoS mechanisms, limiting the delivery of content from the RNC directly to user equipment with desired quality of service (QoS) requirements.
Innovation Solution
A radio network controller (RNC) with an interface to exchange data with user equipment and a gateway node, including a classifier function to intercept and analyze requests, a request analyzer to select modes based on performance indicators, and an application function to request QoS bearers for content delivery from a CDN server located in the RNC.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If content is delivered from the RNC directly to user equipment, then delivery speed and latency are improved, but the ability to prioritize and control QoS is lost
Solution Approach 1:
The patent segments the RNC functionality by introducing separate modular components: a classifier function to identify content requests, a request analyzer to determine QoS requirements, and an application function to establish QoS bearers. This segmentation allows direct content delivery while maintaining QoS control through coordinated interaction between these specialized modules.
Solution Approach 2:
The patent applies preliminary action by establishing QoS bearers before content delivery begins. The classifier function intercepts content requests and analyzes them in advance, determining QoS requirements and establishing appropriate bearers prior to actual content transfer. This ensures QoS is guaranteed from the outset rather than attempted to be managed during delivery.
2Reliability
If QoS mechanisms are applied to RNC functionalities, then service quality is improved, but system complexity increases
Solution Approach 1:
The patent makes the RNC multi-functional by integrating content delivery capabilities (classifier, request analyzer, application functions) alongside traditional QoS management. These new functions work within the existing QoS framework rather than creating parallel systems, allowing the RNC to handle both traditional telecommunication services and content delivery with unified QoS control.
Solution Approach 2:
The patent introduces an intermediary content delivery chain (classifier function → request analyzer → application function) that mediates between content requests and the existing QoS mechanisms. This intermediary layer translates content delivery requirements into QoS bearer parameters without requiring fundamental changes to the core QoS infrastructure, thus managing complexity through layered architecture.
3Loss of energy
If a cache is located in the RNC for content delivery, then traffic load on the network is reduced, but the need for QoS management increases
Solution Approach 1:
The patent applies local quality by placing a cache specifically within the RNC to serve local content delivery needs. This localized caching reduces backhaul traffic and improves delivery speed for cached content. The RNC's classifier and request analyzer functions then apply QoS management specifically to cached content requests, managing complexity by applying QoS only where needed rather than system-wide.

AI summary
A method, computer readable medium and serving node includes an interface configured to exchange data with a user equipment and with a gateway node of a network; and a processor. The processor is configured to implement a classifier function for intercepting a request from the user equipment, and for analyzing whether the request complies with pre-established categorization rules, a request analyzer function for analyzing the request when the request complies with the pre- established categorization rules and for selecting one mode of plural available modes, and an application function for requesting a quality of service, QoS, bearer to be established between the serving node and the user equipment when the selected mode includes a QoS requirement.
