Network switching method and terminal

A terminal, wherein the terminal is a first terminal, and the first terminal comprises a memory, a processor, and a computer program stored in the memory and executable on the processor;

• the computer program, when executed by the processor, causes the first terminal to perform:
• when the first terminal is in a state of a first network connection mode and a first preset triggering condition is detected, switching from the first network connection mode to a second network connection mode;
• wherein one of the first network connection mode and the second network connection mode is that the first terminal is connected to a cellular network, and another of the first network connection mode and the second network connection mode is that the first terminal is connected to a second terminal through a non-cellular network and the second terminal is connected to the cellular network;
• wherein when the first network connection mode is that the first terminal is connected to the cellular network, the first preset triggering condition comprises:
• a non-cellular network connection being established between the first terminal and the second terminal;
• or
• when the first network connection mode is that the first terminal is connected to the second terminal through the non-cellular network and the second terminal is connected to the cellular network, the first preset triggering condition comprises:
• a non-cellular network connection between the first terminal and the second terminal being disconnected;
• before the switching from the first network connection mode to a second network connection mode, the computer program, when executed by the processor, further causes the first terminal to perform:
• transmitting first auxiliary information for switching from the first network connection mode to the second network connection mode to the second terminal;
• the transmitting first auxiliary information for switching from the first network connection mode to the second network connection mode to the second terminal comprises:
• when the first network connection mode is that the first terminal is connected to the cellular network, establishing a non-cellular network connection between the first terminal and the second terminal, and transmitting the first auxiliary information to the second terminal through the non-cellular network connection between the first terminal and the second terminal;
• when the first network connection mode is that the first terminal is connected to the second terminal through the non-cellular network and the second terminal is connected to the cellular network, transmitting the first auxiliary information to the second terminal through the non-cellular network between the first terminal and the second terminal;
• wherein when the first network connection mode is that the first terminal is connected to the cellular network, the first auxiliary information comprises hybrid automatic retransmission request (HARQ) process related information of the first terminal in a connection state, wherein the HARQ process related information comprises an HARQ process number;
• wherein when the first network connection mode is that the first terminal is connected to the second terminal through the non-cellular network and the second terminal is connected to the cellular network, the first auxiliary information comprises at least part of system messages of a network side.

A non-transitory computer readable storage medium, wherein the non-transitory computer-readable storage medium stores a computer program, and the computer program, when executed by a processor of a first terminal, causes the first terminal to perform:

• wherein one of the first network connection mode and the second network connection mode is that the first terminal is connected to a cellular network, and another of the first network connection mode and the second network connection mode is that the first terminal is connected to a second terminal through a non-cellular network and the second terminal is connected to the cellular network;
• wherein when the first network connection mode is that the first terminal is connected to the cellular network, the first preset triggering condition comprises:
• a non-cellular network connection being established between the first terminal and the second terminal;
• or
• when the first network connection mode is that the first terminal is connected to the second terminal through the non-cellular network and the second terminal is connected to the cellular network, the first preset triggering condition comprises:
• a non-cellular network connection between the first terminal and the second terminal being disconnected;
• before the switching from the first network connection mode to a second network connection mode, the computer program, when executed by the processor, further causes the first terminal to perform:
