Multifunctional system capable of simultaneously supporting POC (Ptt over cellular) interphone and TETRA (trans-European trunked radio) interphone on WCDMA-HSPA-LTE(wideband code division multiple access-high speed packet assess-long term evolution system)

Abstract

The invention discloses a multifunctional system capable of simultaneously supporting a POC (Ptt over cellular) interphone and a TETRA (trans-European trunked radio) interphone on WCDMA-HSPA-LTE (wideband code division multiple access-high speed packet assess-long term evolution system), which comprises a PPT (push-to-talk) button, a GPS (global positioning system) module, an SOS (save our souls) button, a WCDMA-HSPA-LTE module, a TETRA module, an application processor, a switcher and a loudspeaker, wherein the application processor is respectively connected with the PPT button, the GPS module, the SOS button, the WCDMA-HSPA-LTE module, the TETRA module and the switcher, and the switcher is connected with the WCDMA-HSPA-LTE module, the TETRA module and the loudspeaker. According to the multifunctional system, the TETRA interphone and the POC interphone can be automatically switched. In addition, the multifunctional system is provided with the SOS button and the PTT button, and has the 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 and TETRA intercom on WCDMA-HSPA-LTE. 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] WCDMA: It is the English abbreviation of Wideband Code Division Multiple Access (Wideband Code Division Multiple Access), and it is a third-generation wireless communication technology. W-CDMA Wi deband CDMA is a third-generation mobile communication system specifically formulated by 3GPP, based on the GSM MAP core network, and UTRAN (UMTS Terrestrial Radio Access Network) as the wireless interface. Currently WCDMA has Releas...
