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

Admission control algorithms integrated with pricing for revenue optimization with QoS guarantees in mobile wireless networks
Naresh Verma,Ing-Ray Chen +1 more
TL;DR: This work proposes and analyze call admission control algorithms integrated with pricing for revenue optimization with QoS guarantee to serve multiple service classes in mobile wireless networks and shows that for a "charge-by-time" pricing scheme, there exist optimal resource allocation settings under which the partitioning and threshold-based admission control algorithm would produce the maximum revenue obtainable by the system without sacrificing QoS requirements.

Call admission control for multi-service mobile networks with bandwidth asymmetry between uplink and downlink
TL;DR: By determining the admissible bandwidth region for the NRT calls, the proposed CAC scheme prevents the calls from overusing the bandwidth resources, and the bandwidth utilization is improved and the blocking probability of the high priority calls can be guaranteed at a low level.
