TLDR
A traffic model and analysis for cellular mobile radio telephone systems with handoff, which shows, for example, blocking probability, forced termination probability, and fraction of new calls not completed, as functions of pertinent system parameters.Abstract:
A traffic model and analysis for cellular mobile radio telephone systems with handoff are described. Three 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 which 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 queueing of handoff attempts is allowed. Appropriate analytical models and criteria are developed and used to derive performance characteristics. These show, for example, blocking probability, forced termination probability, and fraction of new calls not completed, as functions of pertinent system parameters. General formulas are given and specific numerical results for nominal system parameters are presented.read more

Guard channel sharing strategies in integrated voice/data mobile networks
TL;DR: It is proposed that parts of voice guard channels share with data traffic but the voice traffic has higher priority in an integrated voice/data mobile network, which keeps the QoS of both on the voice and data service and increase the bandwidth utilization.

Analysis of new priority queuing strategies for handoff and originating calls in mobile cellular radio systems
R. Beraldi,S. Marano,E. Palumbo +2 more
TL;DR: Analytical results demonstrate that the new proposed schemes with queueing of both handoff calls and originating calls perform better than classic FIFO queueing schemes of only HC because they reduce the blocking probability of OC and increase the carried traffic while assuring the protection of the handoff stream.
Modeling Techniques for
TL;DR: Two new performance models are presented in this article which can be solved using analytical techniques and it is shown that under some assumptions, the analytic techniques are consistent with the simulation model.
