Abstract

A network switching method includes: in the case that a first network connection is established between the network device and a first terminal, instructing the first terminal to make a network connection with the network device through a second terminal. The first terminal is connected to the second terminal through a second network, and the second terminal is connected to the network device through the first network.

Claims (75)

1. A network switching method, applied to a network device and comprising:

responsive to a first network connection being established between the network device and a first terminal, instructing the first terminal to make a network connection with the network device through a second terminal; wherein

the first terminal is connected to the second terminal through a second network, and the second terminal is connected to the network device through the first network; wherein

before the instructing the first terminal to make a network connection with the network device through a second terminal, the method further comprises:

receiving a second network switching request sent by the second terminal; wherein

the second network switching request comprises at least one of:

a radio resource control (RRC) connection establishment request message; or

identification information of the first terminal.

2. The network switching method according to claim 1 , further comprising:

releasing the first network connection with the first terminal.

3. The network switching method according to claim 1 , wherein

the second network switching request further comprises at least one of:

a request message for releasing the first network connection between the first terminal and the network device;

a request message for the first terminal to perform network connection switching, wherein the network connection switching comprises: switching the first network connection between the first terminal and the network device to a second network connection between the first terminal and the second terminal;

a message that the first terminal and the second terminal are connected through a second network;

a request message for switching a preset service from the first terminal to the second terminal;

identification information of the second terminal; or

auxiliary information sent by the second terminal to the first terminal.

4. The network switching method according to claim 1 , wherein the instructing the first terminal to make a network connection with the network device through a second terminal comprises:

sending first response information to the first terminal.

5. The network switching method according to claim 4 , wherein the first response information comprises at least one of:

an acknowledgment message;

identification information of the second terminal;

a radio resource control (RRC) connection release message;

instruction information for instructing the second terminal to initiate RRC connection establishment to the network device through the first terminal; or

a paging message sent to the second terminal.

6. The network switching method according to claim 1 , wherein the instructing the first terminal to make a network connection with the network device through a second terminal comprises:

sending first instruction information to the second terminal.

7. The network switching method according to claim 6 , wherein the first instruction information comprises at least one of:

an acknowledgment message;

a paging message sent to the second terminal;

identification information of the first terminal;

instruction information for releasing the first network connection between the first terminal and the network device;

instruction information for performing network connection switching for the first terminal, wherein the network connection switching comprises: switching the first network connection between the first terminal and the network device to a second network connection between the first terminal and the second terminal;

instruction information for the first terminal and the second terminal to connect through a second network; or

a request message for switching a preset service from the first terminal to the second terminal.

8. The network switching method according to claim 1 , wherein the instructing the first terminal to make a network connection with the network device through a second terminal comprises:

receiving second response information sent by the second terminal.

9. The network switching method according to claim 8 , wherein the second response information comprises at least one of:

an acknowledgment response message;

a radio resource control (RRC) connection establishment request message; or

identification information of the first terminal.

10. The network switching method according to claim 1 , wherein after the first terminal makes a network connection with the network device through a second terminal, the method further comprises at least one of:

sending second instruction information to the first terminal;

receiving request information sent by the first terminal for releasing the first network connection; or

releasing the first network connection with the first terminal.

11. The network switching method according to claim 1 , further comprising:

establishing a radio resource control (RRC) connection with the second terminal; and/or

acquiring first information sent by a core network device; wherein

the first information comprises at least one of:

a contract relationship between the first terminal and the second terminal;

identification information of the second terminal;

subscription information of the first terminal;

subscription information of the second terminal; or

application layer configuration information of the first terminal.

12. The network switching method according to claim 1 , wherein the first network connection means that the first terminal or the second terminal is connected to or camps on a cellular network in RRC_Connected mode, RRC_Idle mode, or RRC_Inactive mode;

the second network connection means a non-cellular network connection between the first terminal and the second terminal.

13. A network device, comprising: a memory, a processor and a computer program that is stored in a memory and executable on a processor, wherein the computer program, when executed by the processor, causes the network device to perform:

responsive to a first network connection being established between the network device and a first terminal, instructing the first terminal to make a network connection with the network device through a second terminal; wherein

the first terminal is connected to the second terminal through a second network, and the second terminal is connected to the network device through the first network; wherein

the computer program, when executed by the processor, causes the network device to further perform:

receiving a second network switching request sent by the second terminal; wherein

the second network switching request comprises at least one of:

a radio resource control (RRC) connection establishment request message; or

identification information of the first terminal.

14. The network device according to claim 13 , wherein the computer program, when executed by the processor, causes the network device to further perform:

releasing the first network connection with the first terminal.

15. The network device according to claim 13 , wherein

the second network switching request further comprises at least one of:

a request message for releasing the first network connection between the first terminal and the network device;

a request message for the first terminal to perform network connection switching, wherein the network connection switching comprises: switching the first network connection between the first terminal and the network device to a second network connection between the first terminal and the second terminal;

a message that the first terminal and the second terminal are connected through a second network;

a request message for switching a preset service from the first terminal to the second terminal;

identification information of the second terminal; or

auxiliary information sent by the second terminal to the first terminal.
