Sound is transferred to control centre；
Digital base stations for receiving the voice calls of digital terminal equipment sending, and pass through IP network for the calling language
Sound is transferred to control centre；
Control centre for receiving the voice calls, and parses corresponding subsonics data from the voice calls,
The call demand of terminal device is parsed from the subsonics data according to the preset subsonics table of comparisons；And exhaling according to terminal device
It makes demand filter out the terminal device that call demand therewith matches, and voice is issued to the obtained terminal device that screens
Calling, to realize the voice intercommunication between two terminal devices.
In conclusion by adopting the above-described technical solution, the present invention at least has the advantages that
By the way that anolog base station, digital base stations, control centre to be connected in unified IP network, newly set not increasing
Realize the modulus voice intercommunication with control signaling under the premise of standby, new channel frequency, saved cost, and control centre with
The two-way communication of same time is realized under the two-way communication of base station, improves voice communication efficiency.
