“…A possible framework of how this can be achieved is described in various papers (see e.g., [61]- [64]) whose models are related either to the Erlang-B formula [61] or the K-R formula [62], [63] or convolution algorithms [64]. In [61], an approximate loss model is proposed for the CBP determination in a system of two access links that cooperate with each other by interchanging capacities using an offloading scheme. This system of links accommodates only one service-class while each link adopts a variant of the CS policy.…”

“…This system of links accommodates only one service-class while each link adopts a variant of the CS policy. The load balancing mechanism of [61] can easily be incorporated in our proposed models. In [62], a multirate loss model that includes a load balancing mechanism is proposed for the CBP calculation in a group of LTE cells that supports non-elastic traffic.…”

Abstract-We consider a reference cell of fixed capacity in a wireless cellular network while concentrating on next-generation network architectures. The cell accommodates new and handover calls from different service-classes. Arriving calls follow a random or quasi-random process and compete for service in the cell under two bandwidth sharing policies: i) a probabilistic threshold (PrTH) policy, or ii) the multiple fractional channel reservation (MFCR) policy. In the PrTH policy, if the number of inservice calls (new or handover) of a service-class exceeds a threshold (different between new and handover calls), then an arriving call of the same service-class is accepted in the cell with a predefined state-dependent probability. In the MFCR policy, a real number of channels is reserved to benefit calls of certain service-classes; thus a service priority is introduced. The cell is modeled as a multirate loss system. Under the PrTH policy, call-level performance measures are determined via accurate convolution algorithms, while under the MFCR policy, via approximate but efficient models. Furthermore, we discuss the applicability of the proposed models in 4G/5G networks. The accuracy of the proposed models is verified through simulation.Comparison against other models reveals the necessity of the new models and policies.

“…[32]- [37]). In the work of [25], the Erlang B formula has been adopted for the determination of CBP in a two access link sys-tem that accommodates Poisson arriving calls of a single service-class. Each access link is modelled as a loss system (i.e.…”

“…By the term offloaded call, we refer to a call that initially arrived in a link, but is served by the other link, if there exist available b.u. The model of [25] does not have a product form solution (PFS) for the steady state probabilities. This is due to the fact that the offloading mechanism destroys local balance (LB) between adjacent states (states that differ only by one call) of the system.…”

We consider a two-link system that accommodates Poisson arriving calls from different service-classes and propose a multirate teletraffic loss model for its analysis. Each link has two thresholds, which refer to the number of in-service calls in the link. The lowest threshold, named support threshold, defines up to which point the link can support calls offloaded from the other link. The highest threshold, named offloading threshold, defines the point where the link starts offloading calls to the other link. The adopted bandwidth sharing policy is the complete sharing policy, in which a call can be accepted in a link if there exist enough available bandwidth units. The model does not have a product form solution for the steady state probabilities. However, we propose approximate formulas, based on a convolution algorithm, for the calculation of call blocking probabilities. The accuracy of the formulas is verified through simulation and found to be quite satisfactory.
