Message receiving system based on 5G NR broadcast and implementation method

[0071] as attached figure 1 As shown, the 5G NR broadcast-based message receiving system of the present invention includes,

[0072] The mobile terminal application program unit is used to set the channel and frequency point by calling the modem interface, instruct the modem to read the program list data in the current cell, and start the reception of the program list; the mobile terminal application program unit adopts the mobile phone app.

[0073] The verification and decryption unit is used to verify and decrypt the data according to its message body structure after receiving the program list data, obtain the original program list data, and perform data analysis;

[0074] The frequency sweep unit is used to close the program list data reception, start the frequency sweep work, and scan the available frequency points: the mobile terminal application program unit calls the frequency sweep interface provided by the modem to sweep the frequency and obtain the frequency sweep r...

[0112] as attached figure 2 As shown, the method for realizing message reception based on 5G NR broadcast of the present invention is to obtain program list data through decryption based on the DatagramSocket timeout mechanism, so as to realize no traffic and support no SIM card mode; the details are as follows:

[0113] S1. The mobile phone app sets the channel and frequency point by calling the modem interface, notifies the modem to read the program list data in the current cell, and the mobile phone app starts receiving the program list;

[0114] S2. After receiving the program list data, perform data verification and decryption according to its message body structure, obtain the original program list data, and perform data analysis;

[0115] S3. Turn off the program list data reception, start the frequency sweep work, and scan the available frequency points: the mobile app calls the frequency sweep interface provided by the modem to sweep the frequency and obtain the freq...

[0125] Embodiments of the present invention also provide a computer-readable storage medium, in which multiple instructions are stored, and the instructions are loaded by a processor to enable the processor to execute the method for implementing 5G NR broadcast-based message reception in any embodiment of the present invention. Specifically, it is possible to provide a system or apparatus equipped with a storage medium on which software program codes for implementing the functions of any of the above-described embodiments are stored, and which enables a computer (or CPU or MPU of the system or apparatus) ) to read and execute the program code stored in the storage medium.
