  • Patent number: 11736979
    Abstract: A data packet transmission method—that includes: obtaining, by a terminal, N application programs that are running; and if the N application programs include an application program including a low-latency service; determining whether an unlicensed frequency band is in a congestion state; and instructing a network device to schedule a data packet of the terminal to a licensed frequency band for transmission when the unlicensed frequency band is in a congestion state. When determining that the N running application programs include the application program including the low-latency service, the terminal may instruct the network device to schedule the data packet of the terminal to the licensed frequency band for transmission, so as to transmit a data packet of the low-latency service by using the licensed frequency band. Resources in the licensed frequency band are centrally scheduled by the network device, instead of being used through contention.
