Exploiting Recurrent Paths of Vehicular Users in a Third Generation Cellular System Urban Scenario

3G telecommunications systems use microcellular radio coverage, where a high capacity is requested. The usage of these, so called, hotspot has its advantages, because the smaller the cell the higher the bit rate, but it also carries some disadvantages like the higher interference level and the larger average number of handover. The latter is particularly perceived by vehicular users, because it can cause serious degradations in the provided quality of service. To exploit microcellular coverage advantages and, at the same time, limiting its disadvantages, this paper presents two algorithms which work on users´ mobility behaviour profile, in order to estimate their recurrent movements and allocate on the future traversed microcells the requested resources in advance. These algorithms introduce remarkable improvements in the grade of service (C.F. Yu et al., 2002) of vehicular users
