The Role of Position Reporting Frequency in LBS QoS Establishment

Position reporting frequency (PRF) is among the main parameters that determine the quality of service (QoS) of location-based services (LBS). Well established PRF provides scalable location awareness for the LBS subject in question. The best description of particular object's location would be obtained if he/she/it were reporting the positioning in very small steps. However, this would soon overburden the network with mostly unnecessary traffic. In order to overcome the limitations of an ideal reporting scheme and preserve acceptable level of location awareness quality, the PRF requirements should be optimised in relation to both available resources and solution performance. This paper addresses a case-related approach for PRF requirements establishment. Three LBS solution paradigms has been chosen for an analysis aimed to yield PRF requirements parameters. PRF parameters have been identified as applicable for a general guidance in more detailed definition of PRF for location-based services
