Network switching method, electronic device, and system on chip

An electronic device, comprising:

• a processor;
• and
• a memory coupled to the processor and configured to store instructions that, when executed by the processor, cause the electronic device to be configured to:
• transmit first data using only a mobile network;
• switch, when a first data transmission delay of a wireless local area network is greater than a first threshold and a second data transmission delay of the mobile network is greater than the first threshold, to perform data transmission using the wireless local area network and the mobile network;
• transmit, responsive to switching to perform the data transmission using the wireless local area network and the mobile network, second data using the wireless local area network and the mobile network;
• switch, when the first data transmission delay is less than the first threshold, to perform the data transmission using only the wireless local area network;
• and
• transmit, responsive to switching to perform the data transmission using only the wireless local area network, third data using only the wireless local area network.

A chip subsystem comprising:

• a modem;
• a Wi-Fi transmitter;
• and
• an application processor coupled to the modem and the Wi-Fi transmitter and configured to:
• transmit first data using only the modem;
• switch, when a first data transmission delay of the Wi-Fi transmitter is greater than a first threshold and a second data transmission delay of the modem is greater than the first threshold, to perform data transmission using the Wi-Fi transmitter and the modem;
• transmit, responsive to switching to perform the data transmission using the Wi-Fi transmitter and the modem, second data using the Wi-Fi transmitter and the modem;
• switch, when the first data transmission delay is less than the first threshold, to perform the data transmission using only the Wi-Fi transmitter;
• and
• transmit, responsive to switching to perform the data transmission using the Wi-Fi transmitter, third data using only the Wi-Fi transmitter.
