IMS Route Calculation via Dynamic Traffic Integration
Find Innovative SolutionsGenerate Solutions
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
Engineering Contradiction Analysis
1Measurement precision
If map cartridges are frequently updated to provide accurate route information, then route calculation accuracy is improved, but cost increases
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
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
2Measurement precision
If dynamic data such as traffic information is integrated into route calculations, then route information accuracy is improved, but device complexity increases
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
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
3Volume of moving object
If GPS units are integrated into mobile phones, then device size is reduced, but functionality is lost
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
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

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.
