Modeling PCS Networks Under General Call Holding Time And Cell Residence Time Distributions - Networking, IEEE/ACM Transactions on

چکیده
In a personal communication service (PCS) network, the call completion probability and the effective call holding times for both complete and incomplete calls are central parameters in the network cost/performance evaluation. These quantities will depend on the distributions of call holding times and cell residence times. The classical assumptions made in the past that call holding times and cell residence times are exponentially distributed are not appropriate for the emerging PCS networks. This paper presents some systematic results on the probability of call completion and the effective call holding time distributions for complete and incomplete calls with general cell residence times and call holding times distributed with various distributions such as Gamma, Erlang, hyperexponential, hyper-Erlang, and other staged distributions. These results provide a set of alternatives for PCS network modeling, which can be chosen to accommodate the measured data from PCS field trials. The application of these results in billing rate planning is also discussed.

A Homogeneous PCS network with Markov Call Arrival Process and Phase Type Cell Residence Time
In this paper, the arrival of calls (i.e., new and handoff calls) in a personal communications services (PCS) network is modeled by a Markov arrival process (MAP) in which we allow correlation of the interarrival times among new calls, among handoff calls, as well as between these two kinds of calls. The PCS network consists of homogeneous cells and each cell consists of a finite number of chan...
متن کاملTeletraffic analysis and mobility modeling of PCS networks
Channel holding time is of primary importance in teletraffic analysis of PCS networks. This quantity depends on user’s mobility which can be characterized by the cell residence time. In this paper we show that when the cell residence time is not exponentially distributed, the channel holding time is not exponentially distributed either, a fact also confirmed by available field data. In order to...
متن کاملCall Performance for a PCS Network
It is well known that, due to the mobility of a portable and limited channel availability, calls of portables may not be completed due to being blocked or terminated during the call initiation or the handover process. The characteristics of the call-completion and call-holding times for both a complete call and an incomplete call are of critical importance for establishing the actual billing pr...
متن کاملAnalytical generalized results for handoff probability in wireless networks
In this letter we present analytical results for handoff probability for wireless networks under assumption that the call holding time and the cell residence time are all generally distributed. Easily computable formulas can be obtained for cases when the call holding time and cell residence time have rational Laplace transforms.
متن کاملEffects of Erlang Call Holding Times on PCS Call Completion
20 leads to an important observation: The call completion probability decreases as the variance of the call holding times decreases. This eeect becomes more signiicant as the variance of the cell residence times decreases. 5 Conclusions This paper introduced a model for studying emerging PCS cellular systems which are expected to exercise at rate billing programs. In this case a more general di...
