Problems solved by technology
[0005] (2) The traditional narrowband communication technology is different from the broadband communication protocol, and the frequency is not available, and the purpose of converged communication cannot be achieved through simple IP interconnection; the media coding standards supported by each communication terminal are inconsistent, and in the communication process, it is necessary to make corresponding adjustments for different terminals Media encoding format conversion and guaranteed media weight
[0006] (3) DMR (Digital Mobile Radio, Digital Mobile Radio) repeater or DMR trunking system (TierIII) channel resources are inherently limited. In the converged intercom conference, if other broadband terminal communication methods are used, the communication connection will always be maintained during the conference. state, it will occupy the channel resources of the repeater for a long time, causing other DMR intercom terminals to fail to communicate due to insufficient channel resources

The present invention provides a broadband and narrowband integrated communication system and method for public private network IP interconnection, wherein the broadband terminal is registered to the FreeSWITCH server through the standard SIP protocol, and the narrowband terminal is registered to the FreeSWITCH server through the DMR repeater or DMR cluster system ;By modifying the FreeSWITCH module source code, the FreeSWITCH server is compatible with the AIS protocol of the DMR repeater, and then through the multimedia encoding and conversion function of FreeSWITCH, the corresponding media encoding format conversion is performed for different terminals, so that broadband terminals and narrowband terminals are integrated together. achieve the function of integrated communication. The present invention can release the DMR channel resources in time through the PTT talk right control, and combined with intelligent routing selection, re-call the corresponding channel that has been offline, and maximize the utilization rate of the channel resources of the repeater.
Description
technical field [0001] The present invention relates to the field of communication technology, in particular, to a broadband and narrowband fusion communication system and method for public and private network IP interconnection. Background technique [0002] In recent years, with the continuous development of network technology, especially the leap from narrowband technology to 4G LTE broadband technology, and the potential market prospects, private network equipment vendors and public network equipment vendors have appeared in the market at the same time. And end users are no longer satisfied with the narrowband requirements of ordinary voice intercom and short data transmission, but instead pursue various multimedia services based on data services. Such as video intercom, conference call, real-time image transmission, location information, voice alarm, etc., in view of the application scenarios of various users and the advantages and disadvantages of public and private ne...
