Specifically, in the communication terminal to be developed in this embodiment, the talkback and other application data are separated, and the two parts are mainly modified, on one hand, the routing table in the kernel is modified, and the separation of the talkback data packet and other application data packet links is realized through the user-defined rule, and on the other hand, the baseband driver is modified, so that the talkback data packet and other application data packets are transmitted through the mobile networks with different frequencies after being modulated and demodulated. Meanwhile, a talkback system is modified and perfected, and talkback grouped data and call data are communicated through an 800M network. When receiving data packets, the information received through different frequency networks is modulated and demodulated, then the corresponding rule is found according to the routing table, and the information is sent to the corresponding application or the talkback application through different links.
Another way to implement the communication terminal to be developed in this embodiment is to integrate two base bands and an antenna in one terminal, which are respectively responsible for modulation and demodulation and data transmission of talkback applications and other applications.
