大多数无线资源管理算法将无线资源管理和呼叫接纳控制(CAC)作为两个不同的过程分开进行。将这两个程序合并到一个单一计划中似乎具有挑战性。本文提出了一种将无线资源管理和概率CAC(PCAC)相结合的新框架。当呼入呼叫请求进入网络时，无线电资源管理使用讨价还价游戏将资源重新分配给正在进行的用户，以确定分配给所有用户的新的资源份额。提出的PCAC算法根据资源分配算法的输出和正在进行的呼叫的服务质量要求动态调整接纳标准。在这个过程中，使用需求函数来确定PCAC所采用的概率参数。给出的性能结果验证了该模型的有效性。
Most radio resource management algorithms engage radio resource management and Call Admission Control (CAC) separately as two different procedures. This incorporation of these two procedures into a single scheme seems challenging. In this paper a novel framework combining radio resource management and Probabilistic CAC (PCAC) is proposed. When an incoming call requests admission to the network, radio resource management reallocates the resources to ongoing users employing a bargaining game to determine the new shares of resources allocated to all users. The PCAC algorithm proposed adjusts dynamically the admission criteria according to the output of the resource allocation algorithm and the QoS requirements of ongoing calls. In this course, a demand function is employed to determine the probabilistic parameter employed by PCAC. The performance results presented verify the improvement achieved by the proposed model.
