Abstract

The invention discloses a multifunctional system simultaneously supporting POC (PTT Over Cellular) talkback and IDEN (Integrated Digital Enhanced Network) talkback on EVDO (Evolution-Data Optimized). The multifunctional system simultaneously supporting the POC talkback and the IDEN talkback on the EVDO comprises a PTT (Push To Talk) button, a GPS (Global Positioning System) module, an SOS (Save Our Souls) button, an EVDO module, an IDEN 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 module, the EVDO module, the IDEN module and the switch respectively; and the switch is connected with the EVDO module, the IDEN module and the loudspeaking device. Due to the adoption of the multifunctional system, automatic switching between the IDEN 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 invention relates to a multifunctional system capable of supporting intercom, more specifically, relates to a multifunctional system capable of simultaneously supporting POC intercom and IDEN intercom on EVDO. 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] EVDO: EVDO is the abbreviation of three words: Evolution (evolution), Data Only. Its full name is: CDMA20001xEV-DO, which is a stage of a path of CDMA2000 1x evolution (3G). This path has two stages of development. The first stage is called 1xEV-DO, or "Data Only", which allows operators to use a CDMA carrier frequency with the same bandwidth as IS-95 or CDMA2000 to achieve up to 2.4Mbps. The forward data transmission rate h...
