摘要
公安部科技信息化局为了实现全国数字集群一张网的目标,于2013年发布了新一代警用数字集群系列标准(PDT)。根据PDT和Tetra标准在语音业务和数据业务的承载能力、性能、语音声码器及组网等方面的规定,结合网络覆盖、用户分布等特点,针对语音组呼和卫星定位等主要业务进行了对比分析。虽然Tetra标准在数据业务上能力上存在一定的优势,但在中国警用广域覆盖和语音通信为主、数据业务为辅的需求前提下,仍可以得出PDT的综合性能更适合中国警用需求的结论。
In order to build a wide wireless digital trunking communication network in China,the Science and Technology Informa-tization Bureau of Ministry of Public Security of the People’ s Republic of China released a series of police digital trunking communica-tion system standards in 2013.According to the definition of PDT and Tetra standard on bearing capacity of voice and data services, performances,vocoder, networking, etc., the primary services such as voice group call and satellite positioning are analyzed and compared combining with such characteristics as network coverage and user distribution. Under the precondition of requiring wide-area coverage and voice communication more than data service for police communication in China, although Tetra standard has some advantages on data service capability,it is concluded that PDT is more suitable for police communication in China.
