本文通过指定一种集成WLAN和地面集群无线电（TETRA）网络的新解决方案，为公共安全通信系统的发展做出贡献。指定的解决方案允许TETRA终端通过宽带WLAN无线接入网连接到TETRA交换和管理基础设施（SwMI），而不是传统的窄带TETRA无线网络。这些终端与传统的TETRA终端完全可互操作，并且可以使用所有TETRA服务，包括组呼、短数据消息传递、分组数据等等。此外，这些终端还可以支持WLAN启用的一系列全新功能，例如宽带数据服务、真正的并发语音和数据服务、同时接收许多组呼叫、减少呼叫设置和语音传输延迟、改进语音质量等等。指定的解决方案完全基于IP多播和IP语音（VoIP）技术，因此非常适合MESA项目为下一代公共安全和救灾通信系统引入的全IP架构。
This article contributes to the evolution of public safety communication systems by specifying a novel solution for integrating WLAN and Terrestrial Trunked Radio (TETRA) networks. The specified solution allows TETRA terminals to interface to the TETRA Switching and Management Infrastructure (SwMI) over a broadband WLAN radio access network, instead of the conventional narrowband TETRA radio network. These terminals are fully interoperable with conventional TETRA terminals and can employ all TETRA services, including group calls, short data messaging, packet data, and so forth. In addition, however, such terminals can support a range of brand new capabilities enabled by the WLAN, such as broadband data services, true concurrent voice and data services, simultaneous reception of many group calls, reduced call setup and voice transmission delays, improved voice quality, and so forth. The specified solution is solely based on IP multicast and Voice-over-IP (VoIP) technologies and thus fits ideally to the all-IP architecture being introduced by the MESA project for the next generation of public safety and disaster relief communication systems.
