Although wireless communicating system in the related technology can be realized convenient and fast wireless communication function, due to being limited to nothing
The technology of line communication, the limited amount of the call terminal 30 of host side connection in usual wireless communicating system, for call
The dilatation of terminal 30 has very big limitation.Based on the above issues, the embodiment of the present application provides a kind of phone system, can solve
The problem of call terminal 30 certainly in the related technology based on wireless communication technique connection is difficult to dilatation, referring to Fig. 1, being the application
The structure chart of phone system shown in one exemplary embodiment.
In embodiment shown in FIG. 1, the phone system, including master controller 10 and at least one wireless processing unit
20。
It should be noted that each wireless processing unit 20 is in the local area network of different frequency range.
The master controller 10 is connect with the wireless processing unit 20 by Internet protocol.
The wireless processing unit 20 handles the call terminal 30 for communicating at least one call terminal 30
Voice signal, and the voice signal is issued into the master controller 10.
The master controller 10, the voice signal sent for receiving each wireless processing unit 20, and by one of them
The voice signal that wireless processing unit 20 is sent is transmitted to other wireless processing units 20；
The wireless processing unit 20 is also used to the voice signal that the master controller 10 forwards being sent to the call
Terminal 30.
In one embodiment, specifically, the master controller 10 is connected with the wireless processing unit 20 by cable network
It connects, to realize the connection between each wireless processing unit 20 of the local area network in different frequency range；Wherein, the wired network

It is communicated based on DECT technology, working frequency range is 1.9GHz or 2.4GHz, and supports time division multiple access technology and complete
The characteristics of duplex call, DECT are the standards determined by ETSI, this technology is to provide high quality, the voice service of low latency；
Support data communication service；Support automatic lossless switching, including carrier wave/time slot caused by degenerating in cell due to the characteristic of channel
Switching, handover caused by user is mobile；Using dynamic channel allocating technology in order, complicated frequency planning is not needed；It is low
Power system；For microcell system, it is possible to provide high traffic density；Using mature technology, to reduce equipment and utilization cost；It can
To data encryption, good confidentiality；There are perfect certification, authentication scheme, safety is good；There are stringent technology rule to air interface
Model is connected with the base station for guaranteeing that the mobile phone of any producer's production can be produced with other producer；A kind of only access technology, does not relate to
And the physical structure of system, the chance of flexibility and the creation of design is provided to each producer；DECT wireless frequency is divided in the world
There is distribution in each state, mainly includes 1.9GHz frequency range and 2.4GHz frequency range.The call terminal realized compared to WiFi technology
Communication connection between 30 and the wireless processing unit 20, the call terminal 30 realized by DECT technology and described wireless
Communication connection between processing unit 20 is more reliable and more stable.
It should be noted that needing when the call terminal 30 is wanted to be added in a session to the wireless processing
Unit 20 initiates access request, and the access request is sent to the master controller 10 by the wireless processing unit 20, described
Access request includes the ID for identifying the call terminal 30, and the master controller 10 is based on the ID and carries out to the call terminal 30
Record is then based on the access request and generates access response, and returns to the wireless processing unit 20, and the wireless processing is single
Member 20 sends it to the call terminal 30, after the call terminal 30 receives the access response, the call
Terminal 30 is added in session.
In one embodiment, after realizing the intercommunication of wireless processing unit 20 of the local area network in different frequency range,
To further realize the multi-party call problem between multiple call terminals 30 that each wireless processing unit 20 communicates, the master control
Device 10 processed is also used to generate according to from the received all voice signals of each wireless processing unit 20 corresponding to each call terminal 30
Audio mixing instruction, and by the audio mixing instruction be sent to corresponding wireless processing unit 20；The then wireless processing unit 20, place
The voice signal for managing the call terminal 30 includes: to receive the audio mixing instruction, according to audio mixing instruction and received institute
There is voice signal (including from the received voice signal of the master controller 10, and from least one call terminal 30 of connection
Received voice signal), the voice signal of the non-call terminal 30 is subjected to stereo process, and the audio signal of generation is sent out
The call terminal 30 is given, then correspondingly, the call terminal 30 is specifically used for receiving the transmission of wireless processing unit 20
Audio signal and broadcasting, it is real to guarantee that the call terminal 30 can receive the voice data of other call terminals 30
The process of existing multi-party call.
