Example 1

Referring to fig. 1, fig. 1 is a schematic structural diagram of a system for performing intercom communication by using an intelligent terminal device according to an embodiment of the present invention; the system comprises intelligent terminal equipment 101 and interphone equipment 102. When the interphone device 102 is a hardware device, the intelligent terminal device 101 and the interphone device 102 are connected in a wired manner or connected through a wireless network; when the intercom device 102 is a software device, software corresponding to the intercom device 102 is installed on the intelligent terminal device 101 to achieve wireless connection. The intercom device 102 realizes intercom communication based on the smart terminal device 101.

The intelligent terminal device 101 may be a portable electronic device communicating with a network server, or may be a device integrated with a network server device. The intercom device 102 may be a hardware device, including various types of intercom, or a software device, including various types of software with intercom function. If the intelligent terminal device 101 is a portable electronic device communicating with the network server and the intercom device 102 is a hardware device, as shown in fig. 1, the intelligent terminal device 101 is connected with the network server 103 in a wireless manner and is connected with the intercom device 102 in a wired or wireless manner.

At present, although the communication can be realized by applying talkback on the intelligent terminal equipment, when the intelligent terminal equipment is positioned in authorized regions of other frequency bands, the problems that the local public talkback channel cannot be quickly and accurately acquired and talkback connection cannot be established exist are solved.

In view of this, an embodiment of the present invention provides a method for performing intercom communication by an intelligent terminal device, as shown in fig. 2, including:

step S201, determining a frequency band authorization region where an intelligent terminal device is located, and loading a public channel frequency set corresponding to the frequency band authorization region;

the authorized region of the frequency band is a region granted with different frequency bands, and may be a region divided by the country or a region divided by other forms.

The method for determining the frequency band authorization region where the intelligent terminal device is located comprises the following three steps:

1) And determining the frequency band authorization region where the intelligent terminal device is located by acquiring the mobile country code MCC of the mobile network used by the intelligent terminal device.

The location area identity LAI contains the mobile country code MCC, which is commonly used in the international mobile subscriber identity and the location area identity. The location area identity LAI is periodically transmitted in a system message broadcast in each mobile network area, wherein the MCC indicates the territory to which the public mobile network of the GSM belongs. The intelligent terminal device takes the received MCC information as one of important bases for network selection.

The IMSI also includes MCC, which indicates a region to which the intelligent terminal device belongs. When the intelligent terminal device logs on to the mobile network or applies for a certain service, the IMSI must be reported to the mobile network. And the mobile network judges whether the user using the intelligent terminal equipment is an international roaming user according to the MCC in the IMSI.

When the intelligent terminal device uses the talkback function in other countries or regions, the public talkback channel of the country or region may not be scanned due to the fact that the public talkback frequency of the country or region is different from that of the country or region. In this case, the user can turn on the talkback scanning function by selecting the frequency sweep.

The method comprises the steps that the intelligent terminal equipment can receive information broadcasted by a GSM network system in a region, the LAI is read from the information, the MCC in the information is extracted, the frequency band authorization region where the intelligent terminal equipment is located can be determined according to the MCC, a public talkback channel frequency set matched with the frequency band authorization region is loaded according to the frequency band authorization region, and the public talkback channel frequency set comprises all public talkback channel frequencies which can be matched.

2) And determining the geographical position of the intelligent terminal equipment through the GPS positioning signal, and determining the frequency band authorization region of the intelligent terminal equipment.

The GPS (Global Positioning System) is a System that performs Positioning and navigation in real time in a Global area by using GPS Positioning satellites, and can provide navigation information such as a low-cost and high-precision three-dimensional position, velocity, and precise timing to Global users. The basic principle of the GPS navigation system is to measure the distance between a satellite with a known position and a user receiver, and then integrate data of multiple satellites to know the specific position of the receiver.

The GPS positioning of the intelligent terminal equipment is realized by utilizing a GPS positioning module on the intelligent terminal equipment to send a position signal of the intelligent terminal equipment to a positioning background. The method comprises the steps that the intelligent terminal device obtains the geographic position of the intelligent terminal device through a GPS positioning module of the intelligent terminal device, determines a frequency band authorization region where the intelligent terminal device is located according to the geographic position, and loads a public talkback channel frequency set matched with the frequency band authorization region according to the frequency band authorization region, wherein the public talkback channel frequency set comprises all public talkback channel frequencies which can be matched.

The GPS positioning mode does not need network access during positioning, so that when a user carries the intelligent terminal device to other frequency band authorization regions, under the condition of no network, the geographic position of the intelligent terminal device can be obtained through GPS positioning of the intelligent terminal device, and the frequency band authorization region where the intelligent terminal device is located is further determined.

The above-mentioned GPS positioning method belongs to the prior art, and the GPS positioning of the intelligent terminal device in this embodiment may adopt the above-mentioned prior art, which is not described in detail here.

3) Outputting prompt information for selecting authorized regions of different frequency bands; and determining the frequency band authorization region where the intelligent terminal device is located according to the received selection information of the frequency band authorization region.

When the frequency band authorization region is determined according to the geographic position of the intelligent terminal device determined by the mobile country code MCC or the GPS positioning signal of the mobile network used by the intelligent terminal device fails, a prompt message is output in the talkback interface to prompt the user to select different frequency band authorization regions. Referring to fig. 3, which is a schematic diagram of a prompt query interface of an intelligent terminal device according to an embodiment of the present invention, a user in intercom communication may view a list of frequency band authorized regions shown in fig. 3 on an interface of the intelligent terminal device, where an arrangement rule of the frequency band authorized regions in the list may be arranged according to initials of frequency band authorized regions as shown in fig. 3, or may be arranged according to other rules, which is not specifically limited in this embodiment.

The method comprises the steps that a user using the intelligent terminal device clicks and selects a corresponding frequency band authorization region in a frequency band authorization region list displayed on an interface according to the geographic position of the user, the intelligent terminal device determines the selected frequency band authorization region as the frequency band authorization region where the intelligent terminal device is located according to received selection information of the frequency band authorization region, a public talkback channel frequency set matched with the frequency band authorization region is loaded according to the frequency band authorization region, and the public talkback channel frequency set comprises all matched public talkback channel frequencies.

Step S202, carrying out talkback test on each public channel frequency in the public channel frequency set;

and respectively setting the public channel frequency in the public talkback channel frequency set determined in the step as the talkback channel frequency of the talkback communication of the intelligent terminal equipment, and starting the talkback mode to carry out talkback test. The talk-back test includes sending a voice message, waiting a predetermined time, which may be, but is not limited to, 200ms, and determining whether a voice reply is received.

If the voice reply is received through the public channel frequency within the preset time, the public channel frequency is considered to be available, and the fact that the talkback test of the public channel frequency is successful is determined; and if the voice reply is not received through the public channel frequency within the preset time, the public channel frequency is considered to be unavailable, and the fact that the talkback test of the public channel frequency fails is determined.

The step of reading the public channel frequency in the public channel frequency set and performing the talkback test is to sequentially read the public channel frequency according to the list sequence of the public channel frequency set and perform the talkback test for all the public channel frequencies in the public channel frequency set until all the public channel frequencies in the public channel frequency set are tested.

Step S203, selecting one common channel frequency from the successfully tested common channel frequencies to perform the intercom communication.

An intercom is a wireless terminal device that can be used in a mobile environment and can communicate with one another at one point to multiple points, allowing multiple users to hear voice information from one user at the same time, but allowing only one user to transmit voice information at the same time.

The interphone consists of a transmitting part, a receiving part, a modulating part and a signaling processing part, and comprises the following four processes when in work:

1) When a user sends voice, the modulation part converts the voice of the user into an audio signal in an electric signal format through a microphone, and the audio signal enters a voltage-controlled oscillator through an amplifying circuit, a pre-emphasis circuit and a band-pass filter to be modulated.

2) When a user sends voice, the transmitting part converts the audio signal generated by the modulating part into a transmitted radio frequency carrier signal through a phase-locked loop and a voltage-controlled oscillator, rated radio frequency power is generated through buffer amplification, excitation amplification and power amplification, harmonic components are suppressed through an antenna low-pass filter, and finally the transmitting antenna transmits the radio frequency carrier signal through available public channel frequency.

3) When a user receives voice, a receiving part adopts a double-conversion superheterodyne mode, a radio frequency carrier signal received from a receiving antenna is subjected to radio frequency amplification through a transceiving conversion circuit and a band-pass filter, enters a first frequency mixer, and is mixed with a first local oscillation signal from a phase-locked loop frequency synthesizer circuit to generate a first intermediate frequency signal; the first intermediate frequency signal further eliminates clutter signals of adjacent channels through a crystal filter, and is mixed with a second local oscillation signal again at an intermediate frequency processing chip to generate a second intermediate frequency signal; the second intermediate frequency signal passes through the useless spurious signal of wave filter filtering and amplifies and distinguishes frequency to it, produces audio signal, audio signal gets into volume control circuit and power amplifier circuit through circuits such as enlarging, filtering, deemphasis, drives the speaker, can convert the speech information and play out.

4) When a user receives voice, the signaling processing part receives a low-frequency signal obtained after frequency discrimination, one part of the low-frequency signal is subjected to filtering and shaping through an amplified and sub-audio band-pass filter and is compared with a preset value, and the result controls the output of an audio power amplifier and a loudspeaker, namely if the low-frequency signal is the same as the preset value, the loudspeaker is turned on, and if the low-frequency signal is different from the preset value, the loudspeaker is turned off.

The talkback process on the intelligent terminal equipment is the same as the working process of the interphone.

After all public channel frequencies in the public channel frequency set are subjected to talkback test, one public channel frequency is selected from the public channel frequencies which are successfully tested to carry out talkback communication.

As an alternative embodiment, the public channel frequencies that have been successfully tested are displayed on the user interface through a list. Referring to fig. 4, which is a schematic diagram of an intelligent terminal device public channel frequency list interface provided in an embodiment of the present invention, a user in intercom communication may view the list of public channel frequencies shown in fig. 4 on the interface of the intelligent terminal device, where an arrangement rule of the public channel frequencies in the list is not specifically limited in this embodiment. The user of the talkback communication can select any one public channel frequency in the list of the public channel frequencies shown in fig. 4 by clicking the corresponding name to perform the talkback communication, and the intelligent terminal device determines the public channel frequency selected by the user as the talkback frequency of the talkback communication according to the operation of selecting the public channel frequency successfully tested by the user.

When the user meets an emergency or has no network, the talkback mode can be started, and the preset public channel frequency is selected to receive channel voice and talk, so that communication can be carried out in time.

As another alternative, one common channel frequency with a signal strength higher than a set threshold may be selected for the intercom communication according to the signal strength of the common channel frequency with which the test is successful. Specifically, the public channel frequencies successfully tested for intercom may be sorted according to the magnitude of the signal strength, the signal strength may be compared with a set threshold, and one public channel frequency may be selected from the public channel frequencies having the signal strength greater than the set threshold for communication. The selection method may be to select a common channel frequency with the highest signal strength for the intercom communication, and is not particularly limited herein.

The implementation process of the above intercom communication belongs to the prior art, and the prior art can be adopted when the intercom communication is implemented on the intelligent terminal device in the embodiment, and details are not described here.
