Abstract

The invention discloses a multifunctional system simultaneously supporting POC (PTT Over Cellular) talkback and TETRA (Trans European Trunked Radio) talkback on CDMA-EVDO-UMB (Code Division Multiple Access-Evolution-Data Optimized-Ultra Mobile Broadband). The multifunctional system simultaneously supporting the POC talkback and the TETRA talkback on the CDMA-EVDO-UMB comprises a PTT (Push To Talk) button, a GPS (Global Positioning System) module, an SOS (Save Our Souls) button, a CDMA-EVDO-UMB module, a TETRA module, an application processor, a switch and a loudspeaking device, wherein the application processor is connected with the PTT button, the GPS module, the SOS button, the CDMA-EVDO-UMB module, the TETRA module and the switch; and the switch is connected with the CDMA-EVDO-UMB module, the TETRA module and the loudspeaking device. Due to the adoption of the multifunctional system, automatic switching between the TETRA talkback and the POC talkback can be realized, and the SOS button, the PTT button and GPS positioning function are realized.

Description

technical field

[0001] The present invention relates to a multifunctional system capable of supporting intercom, more specifically, relates to a multifunctional system simultaneously supporting POC intercom and TETRA intercom on CDMA-EVDO-UMB. Background technique

[0002] PoC (PTT Over Cellular) is also called wireless push-to-talk function. The application of PTT (Push-to-Talk) function on mobile phones is a new mobile technology, which can quickly conduct "one-to-one" or "one-to-many" calls, and its function is similar to that of a walkie-talkie.

[0003] TETRA: Terrestrial Trunked Radio (abbreviated as: TETRA), a standard established by the European Telecommunications Standards Institute since 1995, is a specialized professional radio two-way transmitter (commonly known as a wireless walkie-talkie). TETRA is a communication system designed for use by government agencies, emergency services (police, armed forces, fire stations, ambulances), rail transport, transport serv...
