In this embodiment, after receiving the voice signals sent by the wireless communication unit 203 and/or the voice coding unit, the processing unit 202 performs audio mixing processing based on the received voice signals and each path of equipment of the current call, and if only the user between the wireless call tally submachines 30 is currently performing the call, the processing unit 202 only needs to perform audio mixing processing on the voice signals of the non-designated transmission channel, and sends the generated audio mixing signals to the wireless communication unit 203 through the designated transmission channel; if the user on the wireless communication host 20 is still communicating with the user of the wireless communication talk sub-unit 30, the processing unit 202 also needs to mix the voice signal received from the wireless communication unit 203, and send the generated mixed signal to the voice codec unit 201; then, the wireless communication unit 203 receives the mixed signal transmitted by the processing unit 202 through the designated transmission channel, and then sends the mixed signal to the wireless call talk sub-machine 30, and the voice codec unit 201 plays the mixed signal transmitted by the processing unit 202, so as to implement a process of multiparty full duplex call; the processing unit 202 may be implemented by any one of the following chips: an FPGA chip, a CPU chip, an APU chip or an MCU chip.

When there are 2 devices in the wireless talk system to talk, for example, as shown in fig. 2 and 3, a user talks with the user on the wireless talk master 20 through the voice codec unit 201 provided on the wireless talk master 20 and the user on the wireless talk slave (2), at this time, the processing unit 202 directly sends the voice signals received from both parties as a mixed signal to the counterpart, that is, the processing unit 202 sends the voice signals received from the voice codec unit 201 as a mixed signal to the wireless communication unit 203 through a transmission channel (assuming a transmission channel (2)) corresponding to the wireless talk slave (2), so that the wireless communication unit 203 sends the voice signals to the wireless talk slave (2) and sends the voice signals of the wireless talk slave (2) received from the wireless communication unit 203 as mixed signals to the voice codec unit 201, thereby realizing full duplex of both parties.

If 3 or more than 3 devices in the wireless talk tally system are currently in communication, the processing unit 202 needs to perform audio mixing processing on the audio signals, for example, 3 wireless talk talls of the 1 st sub-machine, the 2 nd sub-machine and the 3 rd sub-machine are currently in communication, the processing unit 202 performs audio mixing processing on the audio signals of the 2 nd sub-machine and the 3 rd sub-machine after receiving the audio signals respectively transmitted by the 3 wireless talk tally sub-machines 30, and transmits the generated audio signals to the wireless communication unit 203 through transmission channels corresponding to the 1 st sub-machine, so that the wireless communication unit 203 transmits the audio signals to the 1 st sub-machine; correspondingly, the processing unit 202 mixes the voice signals of the 1 st sub-machine and the 3 rd sub-machine to generate a mixed signal sent to the 2 nd sub-machine; and mixing the voice signals of the 1-son machine and the 2-son machine to generate a mixed signal which is sent to the 3-son machine, thereby realizing the 3-party full duplex communication process; wherein, the mixing process is a process of accumulating the voice signals.

Referring to fig. 4, a block diagram of a talk over cellular handset 30 according to an exemplary embodiment of the present application is shown. The wireless talk sub-machine 30 includes a wireless communication module 302, a voice encoding and decoding module 303, and a display module 301; the wireless communication module 302 is respectively connected with the voice coding and decoding module 303 and the display module 301.

The voice codec module 303 is configured to transmit an externally acquired voice signal to the wireless communication module 302; and, receiving and playing the audio mixing signal transmitted by the wireless communication module 302; the mixed sound signal is the accumulated result of the voice signals which are not acquired by the user.

The wireless communication module 302 is configured to receive the voice signal of the voice codec module 303 and send the voice signal to the wireless communication host 20; and receiving the audio mixing signal sent by the wireless communication host 20 and transmitting the audio mixing signal to the voice encoding and decoding module 303; and receiving an external tally signal and transmitting the signal to the display module 301.

The display module 301 is configured to display related tally display content based on the tally signal; wherein, the display position of the tally display content on the display module 301 is determined based on the size and type of the display module 301.

Specifically, the wireless communication module 302 establishes a wireless connection with the specified wireless communication unit 203 of the wireless telephony host 20, and the wireless communication module 302 receives a voice signal from the voice codec module 303 and transmits the voice signal to the specified wireless communication unit 203 of the wireless telephony host 20, or receives a mixed signal from the specified wireless communication unit 203 of the wireless telephony host 20 and transmits the mixed signal to the voice codec module 303.

In an example, the wireless communication unit 203 of the wireless communication host 20 and the wireless communication module 302 of the wireless communication talk sub-unit 30 may be wirelessly connected based on WIFI technology, and the wireless communication unit 203 may be a WIFI unit, and accordingly, the wireless communication module 302 is also a WIFI module, and the working frequency band of the WIFI module is 2.4GHz or 5GHz, and the WIFI technology is a common technical means in the prior art and is not described herein.

In another example, since the wireless talk tally system implemented by WIFI technology has network jitter, its stability and reliability are poor, based on this, the present application proposes a more preferable scheme, the wireless communication unit 203 of the wireless talk host 20 and the wireless communication module 302 of the wireless talk tally sub-machine 30 may be wirelessly connected based on DECT technology, the wireless communication unit 203 may be a DECT unit, and accordingly, the wireless communication module 302 is also a DECT module, the working frequency band of which is 1.9GHz or 2.4GHz, DECT is a standard determined by ETSI, and this technology is characterized by providing high quality and low delay voice service; supporting data communication services; supporting automatic lossless handover including carrier/slot handover due to deterioration of channel characteristics in a cell, and handover due to movement of a user; a dynamic channel allocation technology is adopted, so that complex frequency planning is not required; is a low power system; a high traffic density can be provided for a microcell system; mature technology is adopted to reduce equipment and use cost; the data can be encrypted, so that the confidentiality is good; the method has perfect authentication and authentication mechanism and good safety; the air interface has strict technical specifications so as to ensure that mobile phones produced by any manufacturer can be connected with base stations produced by other manufacturers; only one access technology, not related to the physical structure of the system, provides flexibility of design and creation opportunities for various manufacturers; DECT radio frequency division is distributed throughout the world, mainly comprising the 1.9GHz band and the 2.4GHz band. Compared with a wireless tally system realized by a WIFI technology, the wireless tally system realized by a DECT technology is more stable and reliable.

It should be noted that, the number of the wireless talk sub-units 30 connected to the wireless talk host 20 is not limited, but is limited by the existing wireless connection technology, and there is a problem of limitation of the number of the connected wireless talk sub-units 30, for example, when the wireless communication unit 203 of the wireless talk host 20 is wirelessly connected to the wireless communication module 302 of the wireless talk sub-unit 30 based on the DECT technology, the wireless communication unit 203 is a DECT unit, correspondingly, the wireless communication module 302 is a DECT module, and due to the limitation of the DECT technology, one wireless communication unit 203 can only support 4 full duplex talk, that is, one wireless communication unit 203 of the wireless talk host 20 can only connect 4 wireless talk sub-units 30, in order to solve the problem of limitation of connection, the application realizes the expansion of the number of the wireless talk sub-units 30, for example, by setting up 2 wireless communication units 203, thereby realizing the connection of 8 wireless talk sub-units 3030, thereby realizing the connection of a small talk system.

Specifically, the wireless communication unit 203 of the wireless communication host 20 sends the encoded tally signal to the wireless communication module 302 of the wireless communication tally slave 30, so that the wireless communication module 302 transmits the encoded tally signal to the master control module 304 connected thereto after receiving the encoded tally signal; after receiving the coded tally signal transmitted by the wireless communication module 302, the main control module 304 decodes the coded tally signal, and various driving logics are integrated on the main control module 304, so that the main control module 304 can read the size and the type of the display module 301 from the driving module 305 connected with the main control module, and generate display position information, where the display position information includes an initial display line, an initial display point, an end display line and an end display point of the display module 301. It is to be understood that the timing of the main control module 304 to read the size and type of the display module 301 is not limited, and may be, for example, the size and type of the display module 301 may be read when power is applied, or the size and type of the display module 301 may be read when the encoded tally signal is received for the first time.

The portion of the display at the row-column intersection is a display element, i.e., a pixel. A pixel is turned on by applying a positive voltage to the column electrode where the pixel is located and grounding the row electrode. Likewise, to drive an entire row of images, 320 column signals need to be applied to the column electrodes simultaneously, and the row electrodes are grounded. When the line is displayed, other 239 lines cannot be displayed, and the line electrode is high or suspended.

Next, the main control module 304 transmits the decoded tally signal and the display position information to the driving module 305, and it should be noted that, in the present application, there is no limitation on the order of transmitting the decoded tally signal and the display position information to the driving module 305, for example, a principle of first-come first-served transmission may be adopted, then the driving module 305 obtains, according to the decoded tally signal, the corresponding tally display content from the storage module 306, and drives the display module 301 based on the tally display content and the display position information, so that the display module 301 displays the tally display content at a position corresponding to the display position information under the driving of the driving module 305, and it should be noted that, in the present application, there is no limitation on a connection mode between the driving module 305 and the display module 301, for example, the driving module 305 may be connected to the display module 301 through an 8080 interface; the application also does not limit the specific form of the tally display content, for example, animation, text picture or color picture, etc. The wireless communication tally sub-machine 30 integrates the tally display into one sub-machine device, does not need to be externally connected with a tally signal lamp, is more convenient to operate, has high flexibility, is convenient to carry, is simpler and more convenient to use by a user, and is beneficial to improving the use experience of the user.
