Cross-Layer Signaling for Mobile Transceiver Context
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cellular networks face inefficiencies due to high data traffic loads from smartphones and tablets, which are not efficiently managed by base stations, leading to decreased network efficiency and inability to effectively signal context information from higher layers to the Data Link Control (DLC) layer, limiting Quality of Service (QoS) optimization.
Innovation Solution
Implementing cross-layer signaling architectures and protocols that allow mobile transceivers to explicitly signal context information, such as application-layer QoS requirements, from higher layers to the DLC layer, using mechanisms like dedicated control channels and middleware entities within handheld devices to provide accurate and efficient context information to base stations.

Engineering Contradiction Analysis
1Productivity
If conventional cellular networks manage data traffic from smartphones and tablets, then network coverage and connectivity are provided, but network efficiency decreases due to high traffic loads and inability to effectively signal context information
Solution Approach 1:
The patent introduces a feedback protocol as an intermediary mechanism that enables context information to be signaled from higher layers (application layer) to the Data Link Control layer. This mediator allows the base station to receive application-specific context information that was previously inaccessible, enabling more efficient traffic management without reducing overall network capacity.
Solution Approach 2:
The patent changes the signaling parameters by introducing new feedback message structures that carry context information from higher layers. By modifying the Data Link Control layer to accept and process application-layer context parameters, the system enables differentiated resource allocation based on actual application requirements rather than generic traffic handling.
2Reliability
If base stations use conventional Data Link Control signaling, then basic QoS requirements are met, but context information from higher layers cannot be effectively signaled
Solution Approach 1:
The patent adds a new dimension to the signaling architecture by introducing cross-layer feedback mechanisms. Instead of relying solely on traditional vertical protocol layer signaling, the system establishes a feedback path that allows context information to flow from higher layers back to lower layers, creating a multi-dimensional information exchange capability.
Solution Approach 2:
The patent implements a feedback protocol where context information is explicitly signaled from the application layer down to the Data Link Control layer through feedback messages. This feedback mechanism ensures that QoS requirements and context information are reliably transmitted, enabling the base station to make informed resource allocation decisions.
3Adaptability or versatility
If fixed table and header field signaling is used in DLC, then basic QoS classification is achieved, but flexibility to signal utility functions and arbitrary context information is limited
Solution Approach 1:
The patent transforms the static, fixed table-based signaling approach into a dynamic system where context information can be adaptively signaled based on application requirements. The feedback protocol allows the signaling content to change dynamically according to the specific needs of different applications, transitioning from predetermined QoS classes to flexible, context-aware resource allocation.
