Comments on "Teletraffic model and performance analysis for cellular mobile radio telephone systems with prioritized and nonprioritized handoff procedures"

Hong and Rappaport (see Proc. Inst. Electr. Eng., vol.136, pt.I, no.5, p.339-46, 1989) considered a handoff scheme for cellular systems, where priority is given to handoff calls in channel assignment and a queue of handoff calls is allowed. This paper points out and corrects their critical error in getting some performance measures for the scheme. We also discuss the effects of our correction on the related results in their paper and in the paper of Pavlidou (see IEEE Trans. Commun., vol.42, no.2/3/4, p.848-53, 1994).
