Software-Defined Radio Preconditioning for Network Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing software defined radios (SDRs) lack the ability to effectively precondition devices based on anticipated context parameters, such as location, time, and power capacity, which are crucial for optimizing their operational modes and communication protocols.
Innovation Solution
The technique involves determining anticipated context parameters and using them to alter the operational mode of SDR-enabled devices before the context is realized, by employing parameters from local or remote stores, including Web services, to dynamically configure the device for optimal performance, power efficiency, and cost optimization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If SDR devices use fixed radio interfaces for each cellular network, then they can operate on specific networks reliably, but they increase device complexity and cannot adapt to diverse communication environments
Solution Approach 1:
The patent implements a universal software-defined radio interface that can operate across multiple cellular networks (GSM, CDMA, WCDMA, TD-SCDMA) through software configuration rather than hardware-specific interfaces. This allows a single device to perform multiple network operations, reducing the number of separate radio interfaces needed while maintaining reliable operation on each network through software-controlled parameter adjustment
2Adaptability or versatility
If SDR devices dynamically adjust operational modes via software controls, then they gain adaptability to diverse communication environments, but they face challenges in deciding when and how to alter modes to achieve desired goals
Solution Approach 1:
The patent implements a feedback mechanism where the device continuously monitors context parameters (location, time, power capacity, network conditions) and automatically adjusts operational modes based on this feedback. The system evaluates current state against desired goals and dynamically modifies software-defined radio parameters to optimize performance, power consumption, or cost based on real-time conditions
Solution Approach 2:
The patent pre-determines multiple operational modes corresponding to different context scenarios before actual operation. When specific context conditions are detected (such as entering a particular location or time of day), the system can switch to the pre-configured appropriate mode, reducing the computational complexity of real-time decision-making while maintaining adaptability
3Adaptability or versatility
If SDR devices retrieve configuration parameters from remote servers, then they can access updated network protocols, but they experience delays in obtaining parameters when needed for immediate operation
Solution Approach 1:
The patent implements a caching mechanism that pre-loads and stores configuration parameters and software updates locally in the device's memory before they are actually needed. When the device anticipates needing specific network protocols or configuration data (based on predicted location or network conditions), it retrieves and caches this information in advance, eliminating delays when immediate configuration changes are required for operation

AI summary
Techniques are provided for providing automated configuration of computing devices. More particularly, principles of the invention may use anticipated context to precondition a device whose operational mode is alterable via computer controllable operations. Anticipated context may be affected by any number of parameters including, but not limited to, current location, time of day, destination end-point, e.g., phone number to be called, past history, subscription rate plans, power requirements of device, application demands with respect to quality-of-service (QoS), security, calendar information, and so on. Further, principles of the invention may use locally derived knowledge about the intended use of a device and dynamically enable it in a desirable mode of operation using locally reachable configuration parameters stored in advance based on the anticipated context for the operation of the device. Still further, principles of the invention may dynamically locate necessary configuration parameters via a service discovery process.
