Multifunctional system simultaneously supporting POC (Ptt over cellular) intercom and 350M analog trunking intercom on CDMA-EVDO-UMB (Code Division Multiple Access-Evolution Data Optimized-Upper Memory Block)

Abstract

The invention discloses a multifunctional system simultaneously supporting a POC (Ptt over cellular) intercom and a 350M analog trunking intercom on a CDMA-EVDO-UMB (Code Division Multiple Access-Evolution Data Optimized-Upper Memory Block). The multifunctional system comprises a PTT (push-to-talk) button, a GPS (global positioning system) module, a SOS (save our souls) button, a CDMA-EVDO-UMB module, a 350 analog trunking module, an application processor, a switcher and loud-speaking equipment, wherein the application processor is connected with the PTT button, the GPS module, the SOS button, the CDMA-EVDO-UMB module, the 350 analog trunking module and the switcher; and the switcher is connected with the CDMA-EVDO-UMB module, the 350 analog trunking module and the loud-speaking equipment. According to the multifunctional system, the 350 analog trunking intercom and the POC intercom can be automatically switched, and the multifunctional system is also provided with the SOS button and the PTT button and has a GPS positioning function.

Description

technical field [0001] The invention relates to a multifunctional system capable of supporting intercom, more specifically, relates to a multifunctional system simultaneously supporting POC intercom on CDMA-EVDO-UMB and 350M analog trunking intercom. 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] AP; Application Processor (Application Processor), AP is generally used to process the operating system, user interface and applications of mobile phones. [0004] At present, existing devices only support POC intercom or 350M analog trunking intercom on CDMA-EVDO-UMB, but do not implement both in one device at the same time, or do not realize 350M analog trunking intercom and POC intercom There is no automatic ...
