Wireless Proxy for Piconet Data Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for provisioning two-way data communication services with vehicle piconet devices, such as In-Car Navigation Systems and Ultra-Mobile PCs, are costly due to embedded communications modules and high-priced data plans, and lack granular management and bandwidth control.
Innovation Solution
A remotely provisioned wireless proxy within a mobile phone that compiles and manages black, white, and redirect lists of URLs to autonomously control access to network resources, allowing or blocking specific URLs, thereby enabling managed access without the need for a separate wireless front end or tethered data plans.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an embedded communications module is used to provide data communication services, then reliable data communication is achieved, but hardware cost and monthly service cost increase significantly
Solution Approach 1:
The patent introduces a wireless phone as an intermediary device that provides data communication services to piconet devices. Instead of embedding communications modules directly in vehicle devices, the system uses a wireless phone with a web browser to establish the communication bridge, thereby eliminating the need for expensive embedded modules while maintaining reliable data service access
Solution Approach 2:
The wireless phone serves multiple functions: it acts as a communications module, a web browser, and a data service gateway. This multi-functional approach eliminates the need for dedicated embedded communications hardware in vehicle devices, reducing hardware costs while maintaining full data communication capability
2Productivity
If high-priced data plans are used to provide data services, then full bandwidth access is achieved, but monthly service cost increases to $30-$60
Solution Approach 1:
The system enables self-service data access where the wireless phone automatically establishes data connections and manages bandwidth allocation without requiring expensive dedicated data plans. The phone's web browser naturally handles data routing, allowing piconet devices to access the internet through the phone's existing data capabilities at lower cost
Solution Approach 2:
Instead of providing full dedicated data service capability through expensive plans, the system uses the wireless phone's existing data capabilities partially for piconet device access. This partial utilization approach allows multiple devices to share the phone's data connection, reducing the per-device cost while maintaining adequate service levels
3Ease of operation
If conventional data over voice solutions are used, then data communication is enabled, but bandwidth becomes very low and unsuitable for many applications
Solution Approach 1:
The patent replaces voice-based data transmission mechanisms with wireless data communication using the wireless phone's web browser. This substitution eliminates the inherent bandwidth limitations of voice over IP by utilizing the phone's data-capable interface, thereby providing sufficient bandwidth for various applications while maintaining ease of operation
4Ease of operation
If mobile phones are used as modems with tethered data plans, then data service access is provided, but configuration becomes difficult and granular bandwidth management is not possible
Solution Approach 1:
The wireless phone automatically handles data connection establishment, URL filtering, and bandwidth allocation through its web browser and operating system. This self-service approach eliminates the need for complex manual configuration of piconet devices, as the phone autonomously manages data routing and service provisioning without requiring user intervention or complex device settings
Data Source
AI summary
A remotely provisioned proxy within a wireless/mobile phone that proxies a wireless communication path between a disconnected piconet (e.g., BLUETOOTH™) device and a network resource such as a universal resource locator (URL) via a mating mobile phone. Thus, an application proxy module embodied within the mobile phone provides managed access of a piconet device connected to the mating mobile phone to remote services. A disconnected piconet device uses the full data bandwidth available to a wireless phone, without the need for the disconnected piconet device to include its own separate wireless front end, or to require use of a modem within the mobile phone. Thus, using a mobile phone with application proxy, the user need not pay for the luxury of a tethered data plan.
