Abstract

The invention discloses a multifunctional system simultaneously supporting POC (PTT Over Cellular) talkback and IDEN (Integrated Digital Enhanced Network) 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 IDEN 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, 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 button, the CDMA-EVDO-UMB module, the IDEN module and the switch respectively; and the switch is connected with the CDMA-EVDO-UMB 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 present invention relates to a multifunctional system capable of supporting intercom, more specifically, relates to a multifunctional system simultaneously supporting POC intercom and IDEN 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] IDEN: Integrated Digital Enhanced Network, is a digital trunking mobile communication system developed and produced by Motorola Corporation of the United States. Its predecessor is the MIRS system, which was originally designed for trunking shared network applications. Therefore, in addition to command and dispatch services, It also has functions such as duplex telephone interconnection, data and short message. [0004]...
