Traffic Model and Channel Allocation for Two-way Radio Communications

在双向无线电通信中，广泛使用的是Erlang-C业务模型。不过，Erlang的基本概念 它被广泛采用，但并没有涵盖所需的所有方面。要素包括高峰时段的交通密度 包括被阻止和需要重试的呼叫数的时段和因素也包括在内 这很重要，需要纳入其中。在需要减少块调用数量的应用程序中， Erlang模式并不奏效。还需要在Erlang中开发处理排队的其他适应程序 模特。因此，开发一种新的交通控制统计模型对双向交通控制具有重要意义 无线电通讯。因此，在这项提案中，我们希望为双向无线电开发一个现实的流量模型 通讯。双向无线电通信的另一个重要问题是频道的分配。 这样，在保持低操作成本的同时最小化了用户的阻塞概率。我们想要 结合现实交通模式，发展创新的渠道分配机制。

In two way radio communication, Erlang-C traffic model is widely used. Though, the basic Erlang concept was widely adopted, but it did not cover all the aspects required. Elements including traffic density at peak periods and factors to include the number of calls that were blocked and needed to be tried again were also important and needed to be incorporated. In applications, where number of block call needed to be reduced, the Erlang model does not work well. Other adaptations to handle queuing also needed to be developed in Erlang model. Therefore, developing a new statistical model for traffic control is of prime importance for two way radio communication. So, in this proposal, we want to develop a realistic traffic model for two-way radio communications. Another important problem in two-way radio communications is the allocation of channels. As such the blocking probability of the users is minimized while keeping the operating cost low. We want to develop innovative channel allocation mechanisms considering the realistic traffic model.
