Application-Modem Interface for RAN Statistics Discovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication networks face challenges in providing end-to-end Quality of Service (QoS) signaling between wireless devices, leading to packet loss and delay due to handover events and RAN capacity fluctuations, as existing technologies lack effective mechanisms for real-time RAN statistics and QoS requirement exchange.
Innovation Solution
Implementing methods and systems that enable application-level discovery and signaling of Radio Access Network (RAN) statistics and QoS requirements between an application processor and a modem processor, allowing for real-time adaptation of data transmission based on RAN events and QoS metrics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing communication networks operate without application-level RAN statistics visibility, then network infrastructure remains simple, but packet loss and delay increase due to inability to adapt to handover events and RAN capacity fluctuations
Solution Approach 1:
The patent introduces an intermediary interface between the application processor and modem processor that enables RAN statistics visibility without requiring fundamental changes to the entire network infrastructure. This intermediate layer facilitates reliable data transmission by providing application-level awareness of handover events and RAN capacity fluctuations, allowing applications to adapt their behavior accordingly.
Solution Approach 2:
The communication system is segmented into distinct functional layers: the application processor handles high-level application logic, the modem processor manages radio access network protocols, and a new intermediate interface layer provides RAN statistics visibility. This segmentation allows each component to optimize its function while maintaining overall system reliability without excessive complexity.
2Loss of time
If real-time RAN statistics and QoS requirements are exchanged between application processor and modem processor, then packet loss and delay are reduced, but signaling overhead and processing complexity increase
Solution Approach 1:
The patent implements a feedback mechanism where the modem processor provides real-time RAN statistics (such as handover events and capacity information) to the application processor, which then adjusts its data transmission behavior accordingly. This closed-loop feedback reduces transmission delay by enabling applications to respond immediately to changing network conditions without requiring complex centralized control.
Solution Approach 2:
Instead of exchanging all possible QoS parameters and RAN statistics continuously, the system implements selective signaling where only the most critical RAN events and capacity information are transmitted. This partial action approach reduces signaling overhead and processing complexity while still achieving sufficient adaptability to minimize packet loss and delay.
3Ease of operation
If application-level discovery of RAN statistics is implemented, then Quality of Experience improves through real-time adaptation, but interface complexity and protocol overhead increase
Solution Approach 1:
The patent enables applications to self-adjust their data transmission behavior based on received RAN statistics without requiring complex external control or configuration. The application processor autonomously processes RAN event information and modifies its own operation to optimize Quality of Experience, eliminating the need for complex centralized management while maintaining ease of operation.
