Traffic performance analysis of integrated dual-band cellular radio networks

The teletraffic performance of integrated dual-band networks is evaluated. This type of network links two cellular radio systems which have different sets: of frequency bands and the same cell size to a single base station. D ual-band mobile stations use handoff to establish calls on the better syste m. The multidimensional birth-death process is used to characterise the sys tem state and evaluate the performance of dual-band networks in a given cel l. The analytical results show that an integrated dual-band network can pro vide higher offered traffic load than a heterogeneous network, which can on ly handle roaming between two cellular radio systems. The blocking probabil ity and the offered traffic load of the integrated dual-band network are al so calculated by the Erlang-B formula to validate the results.
