本文介绍 MPT—1327标准信令规约的产生过程,以及用于集群系统控制信道的各种信息量控制的形式、信令格式和系统容量。着重介绍该规约的一般话音呼叫程序、特殊呼叫以及与规约有关的其他方面。本规约虽为 Band Ⅲ设计,采用 FFSK 调制,但也适用于其他频段和其他调制方式,是欧洲采用的标准信令规约。 This article describes the generation of the MPT-1327 standard signaling protocol, as well as the forms, signaling formats and system capacities for various information control over the trunking system’s control channel. The general voice calling procedures highlighting the statute, special calls, and other aspects related to the statute. Although this Statute is designed for Band III, FFSK modulation is used, but it is also applicable to other frequency bands and other modulation schemes. It is the standard signaling protocol used in Europe.
