摘　　要：基于dPMR标准,提出了一种呼叫控制层接口的设计方案.介绍了dPMR标准和呼叫控制层的信令格式;数字对讲机三种不同的工作状态并对三种工作状态对讲机的呼叫流程做了说明,基于FPGA平台,利用Verilog HDL语言,对呼叫控制层接口进行了硬件实现,并利用Modelsim进行了仿真验证.The scheme of the call control interface design is proposed based on the protocol of dPMR .The paper first introduces the protocol of dPMR and the signaling format of the call control interface .Then description of three different working status and the calling procedure under the above three working status is presented in detail . Finally ,hardware implementation of the call control interface has been realizedby Verilog HDL ,and the simulation of the call control scheme has been verified by Modelsim .

关 键 词：dPMR 呼叫控制层 信令格式 FPGA
