Customized IMS Applications in order to Improve the Transportation Process
The implementation of information and communication technologies (ICT) is becoming an inevitable factor in optimization of transport processes. In that way, positioning of the vehicle represents an essential element for transport companies in their intention to improve fleet management. There are various technologies applicable for this purpose, but the one discussed in this paper and given as possible solution is using a platform of multiservice telecommunications system (IMS). This solution is represented in a form of Server-based IMS application whose performance results in fleet management control by transport companies. To enable this kind of control it is necessary to perform vehicle position tracking i.e. to define the route of movement. For vehicle location adequate calculations are used based on the vehicle position in relation to the existing infrastructure of mobile networks (global system for mobile communications (GSM), universal mobile telecommunications systems (UMTS)). The application based on this system allows its users to access the desired information from any place, at any time, receiving alarm in the form of short message service (SMS), multimedia messaging service (MMS), e-mail, and to be informed about the possible diversion of the pre-set route. For vehicle location here appropriate algorithm has been implemented on the standard database with input data that refer to the vehicle position obtained on the basis of information of the base stations and any types of standard maps, Google and the similar.
