Traffic Model and Performance Analysis for Cellular Mobile Radio Telephone Systems with Prioritized and Nonprioritized Handoff Procedures - Version 2a

PREFACE This manuscript is an updated version of the frequently referenced VT-86 paper † by Hong and Rappaport, which is among the earliest published analytical treatments of teletraffic modeling for cellular systems. Much work has been done in this field since 1986, but it is not the intention of this manuscript to bring the reader up to date on the subject. Rather, the intention is to make available in one place a " clean " version of the paper which eliminates grammatical and typographical errors that appeared in the original publication and also to correct equation (34) of that paper which contains a mathematical error. The error in equation (34) potentially impacts the computation of several of the system performance curves that were presented. We have recalculated the performance curves using the corrected formula and have compared these to the original curves that were presented. In spite of the error, the original curves are only marginally different from the revised curves in the range of parameters that were presented. Nevertheless, to clarify the record, this manuscript contains a full set of revised figures, which has been calculated on the basis of the corrected formula. In preparing this revision, to the extent possible we have adhered to the wording and numbering of the original paper, except that we have also taken the opportunity to improve grammatical constructions in several places. This revised manuscript will be listed and maintained as a technical report of the College of Engineering and Applied Sciences of the State University of New York and will be available upon request. In addition, an electronic version in Adobe's pdf format will be posted on the Web at the following URL's. The authors wish to thank Joan Borras and Roy Yates for calling the error in equation (34) to their attention. Abstract-A traffic model and analysis for cellular mobile telephone systems with handoff are presented. Three mobile schemes for call traffic handling are considered. One is nonprioritized and two are priority oriented. Fixed channel assignment is considered. In the nonprioritized scheme the base stations make no distinction between new call attempts and handoff attempts. Attempts that find all channels occupied are cleared. In the first priority scheme considered, a fixed number of channels in each cell are reserved exclusively for handoff calls. The second priority scheme employs a similar channel assignment strategy, but, additionally, the queuing of handoff attempts is …
