[0048] The embodiment of the present application discloses an OMA intercom system that supports intercom protocol stack switching.

[0049] Reference Figure 1 An OMA intercom system supporting intercom protocol stack switching includes a Cat4 module 100, an information input module 200, a display module 300, a voice collection module 400, a voice playback module 500, a SIM module 600 and a power supply module 700. The above modules are all arranged in the intercom terminal, with the Cat4 module 100 as the control core, and the other modules are coupled to the Cat4 module 100.

[0050] Specifically, the Cat4 module 100 is a communication CPU of ARM architecture, configured with 128M RAM and 128M ROM, and runs the Linux embedded operating system; the Cat4 module 100 includes an intercom protocol stack running unit 101, an abnormal information receiving unit 102, a protocol stack switching information judgment unit 103 and an intercom protocol stack switching unit 104. The intercom protocol stack running unit 101 is used to run the intercom protocol stack and connect to the intercom channel corresponding to the intercom protocol stack through the intercom protocol stack to realize user intercom. In one embodiment of the present application, an intercom protocol stack based on the OMA standard and a third-party private intercom protocol stack are pre-set. When the system performs intercom, the intercom information received is encoded and transmitted through the intercom protocol stack; the abnormal information receiving unit 102 is used to receive abnormal information, which may be caused by the instability of the operator platform, resulting in the user being unable to access the corresponding intercom channel through the intercom protocol stack. When the user visits the intercom multiple times, After the intercom channel fails, an exception message will be generated. In another embodiment of the present application, the exception message can be manually typed by the user. When the user realizes that the intercom channel is unavailable, the user can manually type the exception message to switch the intercom protocol stack. The protocol stack switching information judgment unit 103 is used to determine whether the exception message is the protocol stack switching information. The protocol stack switching information can be customized. The above-mentioned manual typing method to generate exception information is used as an example for explanation. When the user types specific information in a specific interface, the exception message is determined to be the protocol stack switching information. In one embodiment of the present application, the specific information typed by the user in a specific interface can be set to press the up direction key 5 times in a row in the About Version interface of the system UI interface. The intercom protocol stack switching unit 104 is used to drive the intercom protocol stack running unit 101 to complete the switching of the intercom protocol stack according to the protocol stack switching information.

[0051] The information input module 200 is used to realize the human-computer interaction of the system. The information input module 200 can be various function keys set on the intercom terminal, including PTT key, volume adjustment key, function key, setting key, up and down selection keys and power switch key. It should be noted that the PPT key is the transmission key. When the user presses the PPT key and talks, the intercom content will be sent when the user releases the PPT key.

[0052] The display module 300 is used to display the UI interface of the system. The display module 300 may be an LCD screen. The UI display interface is generated based on the LVGL library.

[0053] The voice collection module 400 is used to collect intercom information. The voice collection module 400 may be a microphone. The intercom information and the user voice spoken by the user into the microphone are collected in PCM at a sampling rate of 8K / 16BIT.

[0054] The voice playing module 500 is used to play the intercom information received from the intercom channel and sent by other users through other intercom terminals. The voice playing module 500 can be a speaker.

[0055] The SIM module 600 is used to access the operator's 4G network.

[0056] The power supply module 700 is used to supply power to the system through a portable lithium battery.

[0057] Through the above system, the system can realize user intercom, and complete the switching of the system intercom protocol stack according to the received protocol stack switching information. The specific intercom and protocol stack switching process in one embodiment of the present application is as follows:

[0058] The system runs the intercom protocol stack based on the OMA standard by default when it is powered on. It initiates registration with the OMA platform and logs in to the OMA intercom platform. After successful login, it initiates the channel access process and accesses the predefined channel. When the user sends a voice, the user presses PTT to speak and sends the TBCP protocol to apply for the right to speak. After the right to speak is successfully applied for, the collected PCM data is compressed and encoded into an AMR format voice packet, and sent to the OMA intercom platform through the RTP protocol. Other intercom terminals in the same channel can receive the real-time voice sent by this system. When the user receives the voice sent by other intercom terminals in the same channel, the AMR format voice packets sent by other intercom terminals are decompressed into PCM data for playback and received by the user, completing the user's operation of sending and receiving voice, and enabling the user to intercom with other intercom terminals through the system.

[0059] Please refer to Figure 2 , a flowchart of a feasible intercom protocol stack switching method of the present application is provided. When the user hopes to switch to a third-party private intercom protocol stack when running an intercom protocol stack based on the OMA standard, the intercom protocol stack switching can be completed by inputting protocol stack switching information into the system. In one embodiment of the present application, the protocol stack switching information is set to press the up arrow key 5 times in succession in the About Version interface of the system UI interface. At this time, a protocol stack selection prompt box will pop up in the system UI interface. After the user presses OK, the system can immediately switch to the third-party private intercom protocol stack, and at the same time exit the OMA intercom platform, disconnect the connection with the OMA platform channel, log in to the third-party intercom platform, access the channel of the third-party intercom platform, and perform the aforementioned intercom operation.

[0060] Similarly, when the user wants to switch the third-party private intercom protocol stack to the intercom protocol stack based on the OMA standard during runtime, the user inputs the protocol stack switching information to the system, and a protocol stack selection prompt box will pop up in the system UI interface. After the user presses OK, the system will immediately switch to the intercom protocol stack based on the OMA standard, exit the third-party intercom platform, disconnect from the third-party intercom platform channel, log in to the OMA intercom platform, and access the channel based on the OMA intercom platform.

[0061] Based on the above modules, when the present application is actually applied, first insert the 4G card into the SIM module 600, start the system through the power supply module, load the system through the Cat4 module 100 and run the intercom protocol stack program to access the public network intercom platform, and display the loaded system UI interface through the display module 300; then, select the channel to be accessed through the information input module 200; when the PTT key is pressed to initiate a call, the voice receiving module starts to collect input audio data, and the Cat4 module 100 compresses the collected audio data in PCM format into voice packets in AMR format and transmits them to the public network intercom platform, thereby realizing the voice intercom sending function; and when the system accepts a call, the AMR voice packet received from the network is decoded into audio data in PCM format and played through the voice playback module 500, thereby realizing the voice intercom receiving function.

[0062] When the intercom system is started, the Cat4 module 100 starts the intercom protocol stack based on the OMA standard by default. The system logs in to the OMA intercom platform and accesses the predefined channel of the OMA intercom platform to implement intercom. When it is necessary to switch the intercom protocol stack based on the OMA standard to a third-party private protocol stack, the user enters information through the information input module 200. The abnormal information receiving unit 102 in the Cat4 module 100 receives the user-entered information and determines whether the user-entered information is abnormal information. When it is determined to be abnormal information, the protocol stack switching information determination unit 103 determines whether the abnormal information is protocol stack switching information. If it is protocol stack switching information, an interrupt instruction is generated through the intercom protocol stack switching unit 104 to interrupt the connection between the system and the intercom channel corresponding to the intercom protocol stack based on the OMA standard. After terminating the connection with the current intercom channel, the system is switched to the third-party private protocol stack, and an access instruction is generated to access the intercom channel corresponding to the third-party private protocol stack to complete the switching of the intercom protocol stack.

[0063] The implementation principle of an OMA intercom system supporting intercom protocol stack switching in the embodiment of the present application is as follows: user intercom is realized through various modules set on the intercom terminal, with Cat4 module 100 as the core, when there is a problem with the intercom protocol stack currently used by the user, abnormal information is generated, protocol stack switching information is generated according to the abnormal information, and the intercom protocol stack based on the OMA standard and the third-party private protocol stack preset in the Cat4 module 100 are switched through the protocol stack switching information. When the current intercom protocol stack is unavailable, the user can switch to another intercom protocol stack in time for intercom, avoiding the intercom operation of the user being affected.

[0064] The embodiment of the present application also discloses an OMA intercom method that supports intercom protocol stack switching.

[0065] Reference Figure 3 , an OMA intercom method supporting intercom protocol stack switching comprises the following steps:

[0066] Receiving the abnormal information;

[0067] Determining whether the abnormal information is the protocol stack switching information;

[0068] If yes, the intercom protocol stack is switched according to the protocol stack switching information.

[0069] The above is only an exemplary embodiment of the present disclosure, and the scope of the present disclosure cannot be limited thereto. That is, any equivalent changes and modifications made according to the teachings of the present disclosure are still within the scope of the present disclosure. After considering the specification and practicing the disclosure here, those skilled in the art will easily think of other embodiments of the present disclosure.
