Multifunctional system for simultaneously supporting POC (push-to-talk over cellular) talkback and 350M analog trunked talkback on TD-SCDMA (time division-synchronous code division multiple access)

Abstract

The invention discloses a multifunctional system for simultaneously supporting POC (push-to-talk over cellular) talkback and 350M analog trunked talkback on TD-SCDMA (time division-synchronous code division multiple access). The multifunctional system comprises a PTT (push-to-talk) button, a GPS (global positioning system) module, an SOS (save our souls) button, a TD-SCDMA module, a 350M analog trunked module, an application processor, a switcher and loudspeaker equipment, wherein the application processor is used for operating and controlling a POC protocol stack; the switcher is used for switching between the 350M analog trunked talkback and the POC talkback; the application processor is respectively connected with the PTT button, the GPS module, the SOS button, the TD-SCDMA module, the 350M analog trunked module and the switcher; and the switcher is also connected with the TD-SCDMA module, the 350M analog trunked module and the loudspeaker equipment. The multifunctional system disclosed by the invention can realize automatic switching between the 350M analog trunked talkback and the POC talkback, and has the SOS button, the PTT button and the GPS 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 TD-SCDMA and 350M analog cluster 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] TD-SCDMA: Time Division-Synchronous Code Division Multiple Access (English: Time Division-Synchronous Code Division Multiple Access, abbreviated as: TD-SCDMA), is one of the three 3G standards approved by the ITU, China Mobile since 2008 The TD-SCDMA network has been deployed nationwide, and it is operating with number distribution for users. [0004] AP; Application Processor (Application Processor), AP is generally ...

AI Technical Summary

Problems solved by technology

[0005] At present, existing devices only support POC intercom or only 350M analog trunk intercom, but do not implement both in one device at the same time, or do not realize the automatic switching function between 350M analog trunk intercom and POC intercom, or do not have Integrated GPS positioning function, or no integrated SOS button, or no integrated PTT button
