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.

在双向无线通信中，Erlang-C业务模型被广泛应用。不过，基本的Erlang概念 它被广泛采用，但它没有涵盖所需的所有方面。高峰期交通密度等要素 期间和因素，包括被阻止的呼叫数，需要再次尝试， 重要的是，需要被纳入。在需要减少块调用数量的应用程序中， Erlang模型不能很好地工作。在Erlang中还需要开发处理排队的其他适配 模型因此，开发一种新的交通控制统计模型，对两种方式都具有重要意义。 无线电通讯因此，在本提案中，我们希望为双向无线电建立一个现实的交通模型 通讯双向无线电通信中的另一个重要问题是信道的分配。 这样，在保持低操作成本的同时，用户的阻塞概率被最小化。我们想 考虑到现实的交通模型，开发创新的渠道分配机制。
