Solution Overview

Problem

Current GPS and route calculation services, especially in mobile devices, lack real-time updates and dynamic data such as traffic jams, accidents, and road conditions, leading to inaccurate route information and the need for frequent map cartridge replacements.

Innovation Solution

An IP Multimedia Subsystem (IMS) network-based route calculation service that processes fixed and dynamic parameters, including traffic information, to provide accurate and up-to-date route options, using an application server connected with transport media servers and navigational systems, and displaying these routes on a map.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If map cartridges are frequently updated to provide accurate route information, then route calculation accuracy is improved, but cost increases

Engineering Contradiction:
Improveroute calculation accuracyVSAvoidcost
Core Design Contradiction:
Measurement precisionVSLoss of substance

Solution Approach 1:

The patent replaces the mechanical map cartridge system with an electronic database system connected to the network. Instead of physically replacing map cartridges to update route information, the system uses electronic data transmission through the network to update route databases, thereby eliminating the need for frequent physical cartridge replacements and associated costs while maintaining high route calculation accuracy

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent creates a virtual copy of the map database system in the network domain. Rather than updating physical map cartridges, the system maintains an electronic copy of route data that can be remotely updated and synchronized, allowing accurate route information to be provided without the costs and complexities of physical cartridge replacement

Inventive Principle:
Principle #26Copying

2Measurement precision

If dynamic data such as traffic information is integrated into route calculations, then route information accuracy is improved, but device complexity increases

Engineering Contradiction:
Improveroute information accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent introduces a network system as an intermediary between the mobile device and the route calculation database. The network handles the complex tasks of collecting, processing, and integrating dynamic data such as traffic information, while the mobile device simply queries and receives results. This intermediary approach enables accurate route information with dynamic data integration without significantly increasing the complexity of the mobile device itself

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent moves the complexity of dynamic data processing from the device dimension to the network dimension. By shifting the computational burden to the network infrastructure, the system can integrate multiple data sources including traffic information without overloading the mobile device, thereby maintaining route information accuracy while managing system complexity through dimensional distribution

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Volume of moving object

If GPS units are integrated into mobile phones, then device size is reduced, but functionality is lost

Engineering Contradiction:
Improvedevice sizeVSAvoidfunctionality
Core Design Contradiction:
Volume of moving objectVSAdaptability or versatility

Solution Approach 1:

The patent makes the network-based route calculation system universally accessible to multiple devices including mobile phones, tablets, and other portable devices. By providing a standardized interface and network-based database access, the system delivers complete GPS and route calculation functionality through various device types without requiring each device to have dedicated hardware, thus maintaining small device size while preserving full functionality

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The network acts as an intermediary that provides GPS and route calculation services to mobile devices without requiring integrated GPS hardware in each device. The network infrastructure handles positioning and route calculation tasks, enabling mobile phones to access complete navigation functionality while maintaining their compact form factor

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

Currently existing web applications for calculation of routes from an origin to a destination do not take into account traffic jams, road/rail reparations, accidents, or other temporary incidents. To overcome this drawback, the present specification provides for new network entities and method of providing a subscriber of an IP Multimedia Subsystem "IMS" network with a route to a destination, wherein this method comprises a step of receiving at an application server "AS" associated with the IMS network dynamic parameters from a plurality of transport media indicating respective incidental information, and a step of processing at the AS these dynamic parameters along with other input criteria to determine a number of routes from the origin to the destination.
