Abstract

Claims (45)

1. A network slice connection method, applicable to a terminal device in a same device group, the method comprising:

acquiring, in response to acquiring a slice connection triggering signal, first network slice information and device information of the terminal device in the device group and generating a terminal device identifier list according to the device information;

acquiring, in response to acquiring selection information indicating a selection of a target terminal device identifier from the terminal device identifier list, device information of a target terminal device corresponding to the target terminal device identifier according to the selection information; and

transmitting the first network slice information and the device information of the target terminal device to a server, such that the server connects the target terminal device to a network slice related to the first network slice information according to the first network slice information and the device information of the target terminal device.

2. The method of claim 1 , wherein acquiring first network slice information and device information of the terminal device in the device group comprises:

reading the first network slice information;

transmitting a terminal device information request message to the server; and

acquiring the device information of the terminal devices in the device group which is fed back by the server according to the terminal device information request message.

3. The method of claim 2 , wherein transmitting the first network slice information and the device information of the target terminal device to a server comprises:

initiating a Protocol Data Unit (PDU) session establishment request to the server by utilizing the first network slice information, and carrying the device information of the target terminal device in an uplink non-access stratum transport message.

4. The method of claim 3 , after initiating a PDU session establishment request to the server by utilizing the first network slice information, and carrying the device information of the target terminal device in an Uplink Non-access Stratum Transport (UL NAS Transport) message, the method further comprising:

acquiring second network slice information in response to receiving a first reject message from the server; and

initiating a PDU session establishment request to the server by utilizing the second network slice information, and carrying the device information of the target terminal device in an UL NAS Transport message.

5. The method of claim 4 , further comprising:

acquiring third network slice information in response to receiving a second reject message from the server after successfully establishing a PDU session with the server; and

initiating a PDU session establishment request to the server by utilizing the third network slice information, and carrying the device information of the target terminal device in an UL NAS Transport message.

6. The method of claim 3 , further comprising:

acquiring third network slice information in response to receiving a second reject message from the server after successfully establishing a PDU session with the server; and

initiating a PDU session establishment request to the server by utilizing the third network slice information, and carrying the device information of the target terminal device in an UL NAS Transport message.

7. The method of claim 1 , wherein acquiring first network slice information and device information of the terminal device in the device group comprises:

transmitting a terminal device information request message to the server; and

acquiring the device information of the terminal devices in the device group and the first network slice information corresponding to the terminal devices in the device group which are fed back by the server according to the terminal device information request message.

8. The method of claim 7 , wherein transmitting the first network slice information and the device information of the target terminal device to a server comprises:

initiating a network slice connection request to the server;

acquiring a slice information request message fed back by the server according to the network slice connection request;

transmitting the first network slice information to the server according to the slice information request message;

acquiring a device information request message fed back by the server according to the first network slice information; and

transmitting the device information of the target terminal device to the server according to the device information request message.

9. The method of claim 1 , further comprising:

in response to receiving a device trigger message carrying fourth network slice information from the server, connecting to a network slice according to the fourth network slice information in the device trigger message.

10. The method of claim 9 , wherein connecting to a network slice according to the fourth network slice information in the device trigger message comprises:

parsing the device trigger message to obtain the fourth network slice information;

performing security verification on the fourth network slice information; and

connecting to the network slice according to the fourth network slice information in response to the fourth network slice information passing the security verification.

11. The method of claim 1 , in response to the first network slice information being network slice information corresponding to the terminal device, directly reading the first network slice information from the terminal device.

12. The method of claim 1 , in response to the first network slice information being network slice information corresponding to another terminal device in the device group, acquiring the first network slice information through the server.

13. The method of claim 1 , after generating the terminal device identifier list according to the device information, displaying the terminal device identifier list on a display screen of the terminal device.

14. A terminal device, comprising: a memory, a processor, and a computer program stored in the memory and executable by the processor which, when executed by the processor, causes the processor to perform a network slice connection method, applicable to a terminal device in a same device group, the method comprising:

acquiring, in response to acquiring a slice connection triggering signal, first network slice information and device information of the terminal device in the device group and generating a terminal device identifier list according to the device information;

acquiring, in response to acquiring selection information indicating a selection of a target terminal device identifier from the terminal device identifier list, device information of a target terminal device corresponding to the target terminal device identifier according to the selection information; and

transmitting the first network slice information and the device information of the target terminal device to a server, such that the server connects the target terminal device to a network slice related to the first network slice information according to the first network slice information and the device information of the target terminal device.

15. A non-transitory computer-readable storage medium, storing computer-executable instructions which, when executed by a processor, cause the processor to perform a network slice connection method, applicable to a terminal device in a same device group, the method comprising:

acquiring, in response to acquiring a slice connection triggering signal, first network slice information and device information of the terminal device in the device group and generating a terminal device identifier list according to the device information;

acquiring, in response to acquiring selection information indicating a selection of a target terminal device identifier from the terminal device identifier list, device information of a target terminal device corresponding to the target terminal device identifier according to the selection information; and
