MOBILITY MODELING AND TRAFFIC ANALYSIS IN 3-DIMENSIONAL INDOOR ENVIRONMENTS

To efficiently plan future personal communications services (PCS's), w e need to solve various mobility/traffic problems in one-dimensional ( 1-D), two-dimensional (2-D), and three-dimensional (3-D) micro or pico cell environments. However, mobility/traffic problems have thus far pr imarily been studied in 1-D and 2-D cell structures, In this paper, we extend the previous mobility modeling from 1-D or 2-D space to 3-D in door building environments by considering the proper boundary conditio ns on each floor and analytically modeling mobility in multistory buil dings to estimate the number of handoffs, We then propose a blocking p robability model with mobility as a traffic model in 3-D indoor enviro nments. Utilizing this model, we can obtain the required number of cha nnels per cell under the given blocking probability constraint, These results can be utilized in planning the networks of future PCS's.
