Abstract

The invention discloses a device for realizing communication between a 350M analog cluster talkback system and a POC (PTT Over Celluar) talkback system. The device comprises an interface gate device, wherein the interface gate device comprises a main control module, a 350 cluster system signaling analyzing module, a 350 cluster system voice packet analyzer, a POC function module, a cluster member mapping table, an AD / DA (Analog-Digital / Digital-Analog) conversion module and a voice encoding and decoding device; the main control module is connected with a 350M analog cluster system server respectively by the 350 cluster system signaling analyzing module and the 350 cluster system voice packet analyzer, and is connected with the POC function module, the cluster member mapping table and the AD / DA conversion module; the AD / DA conversion module is connected with the POC function module by the voice encoding and decoding device; and the POC function module is in wireless connection with a POC cluster system server by the Internet. According to the device disclosed by the invention, the communication between the 350M analog cluster talkback system and the POC (PTT Over Celluar) talkback system is realized and the mutual communicating performance is good.

Description

technical field [0001] The practical technology relates to a device for enabling two different intercom systems to communicate, more specifically, a device for enabling communication between a 350M analog trunking intercom system and a POC intercom system. Background technique [0002] Analog trunking system: use analog modulation for communication, and introduce multi-channel sharing technology. The signaling standard of analog trunking system is MPT-1327, which has strong scalability. Generally, digital signaling is used. Due to the limited grouping resources of analog cluster system , The system functions need to be increased, and the price of the current digital trunking mobile communication system is relatively high. It is unrealistic for the user to scrap all the original analog system equipment at one time and switch to the digital system equipment. More "smooth transition" solutions can be used. Enable true coexistence of analog and digital systems. [0003] The net...
