Abstract
To address the communication demands in the emergency communication industry,where private networks feature precise but limited coverage and public networks feature extensive coverage but weak professional scheduling capabilities,this study proposes a converged trunking communication system solution applied to the interconnection between public network POC systems and private network PDT systems.This study elaborates the overall architecture design concept of the system,analyzes the key technologies for realizing interconnection between heterogeneous systems,and sorts out the important service processes between systems,including call setup,call release,floor control,and short message forwarding.This study builds a full-scenario converged communication test environment to conduct multi-dimensional and full-process verification of the basic service and interconnection functions of the system.Verification results show that the proposed converged communication system solution can effectively meet the interconnection requirements between PDT and POC systems,provide stable,efficient,and low-latency communication support for emergency communication scenarios,and adapt to the dual communication demands of daily office work and emergency support in the emergency industry.关键词
