Abstract

The present disclosure discloses a method and a device for information transmission, capable of enabling a terminal device to efficiently identify a network to which identification information it receive is to be applied. The method includes: receiving, by a terminal device, identification information transmitted by a network device; and determining, by the terminal device, whether the identification information is to be used in a non-public network based on an indication from the network device, an environment in which the identification information is received, or content of the identification information.

First claim

What is claimed is:

1. A method for information transmission, comprising:
receiving, by a terminal device, identification information transmitted by a network device, wherein the identification information comprises a Globally Unique Temporary Identifier (GUTI), the GUTI comprises a Public Land Mobile Network (PLMN) identifier (ID) and does not comprise a Network Identifier (NID); and
determining, by the terminal device, whether the identification information is to be used in a non-public network based on an environment in which the identification information is received,
wherein when the terminal device receives the GUTI in a current non-public network where the terminal device is residing, the GUTI is only used when accessing the current non-public network; and
wherein the non-public network comprises a Standalone Non-Public Network (SNPN), and the SNPN has an SNPN identifier comprising a PLMN ID and an NID.

2. The method of claim 1 , further comprising:
associating, by the terminal device, the identification information with the non-public network; and storing the association by the terminal device.

3. A terminal device, comprising a processor and a memory, wherein the memory is configured to store a computer program, and the processor is configured to invoke and execute the computer program stored in the memory to:
receive identification information transmitted by a network device, wherein the identification information comprises a Globally Unique Temporary Identifier (GUTI), the GUTI comprises a Public Land Mobile Network (PLMN) identifier (ID) and does not comprise a Network Identifier (NID); and
determine whether the identification information is to be used in a non-public network based on an environment in which the identification information is received,
wherein when the terminal device receives the GUTI in a current non-public network where the terminal device is residing, the GUTI is only used when accessing the current non-public network; and
wherein the non-public network comprises a Standalone Non-Public Network (SNPN), and the SNPN has an SNPN identifier comprising a PLMN ID and an NID.

4. The terminal device of claim 3 , wherein the processor is further configured to invoke and execute the computer program stored in the memory to:
associate the identification information with the non-public network; and store the association.

5. The method of claim 2 , further comprising:
deleting the identification information when the terminal device leaves the non-public network.

6. The method of claim 1 , further comprising:
transmitting, by the terminal device, indication information to the network device, the indication information indicating that the terminal device has accessed the non-public network.

7. The terminal device according to claim 4 , wherein the processor is further configured to invoke and execute the computer program stored in the memory to:
delete the identification information when the terminal device leaves the non-public network.

8. The terminal device according to claim 3 , wherein the processor is further configured to invoke and execute the computer program stored in the memory to:
transmit indication information to the network device, the indication information indicating that the terminal device has accessed the non-public network.

9. A chip, comprising a processor, wherein the processor is configured to invoke and execute a computer program from a memory to cause a device provided with the chip to:
receive identification information transmitted by a network device, wherein the identification information comprises a Globally Unique Temporary Identifier (GUTI), the GUTI comprises a Public Land Mobile Network (PLMN) identifier (ID) and does not comprise a Network Identifier (NID); and
determine whether the identification information is to be used in a non-public network based on an environment in which the identification information is received,
wherein when the terminal device receives the GUTI in a current non-public network where the terminal device is residing, the GUTI is only used when accessing the current non-public network; and
wherein the non-public network comprises a Standalone Non-Public Network (SNPN), and the SNPN has an SNPN identifier comprising a PLMN ID and an NID.

10. The chip according to claim 9 , wherein the processor is configured to invoke and execute the computer program from the memory to cause the device provided with the chip to:
associate the identification information with the non-public network; and store the association.

11. The chip according to claim 10 , wherein the processor is configured to invoke and execute the computer program from the memory to cause the device provided with the chip to:
delete the identification information when the terminal device leaves the non-public network.

12. The chip according to claim 9 , wherein the processor is configured to invoke and execute the computer program from the memory to cause the device provided with the chip to:
transmit indication information to the network device, the indication information indicating that the terminal device has accessed the non-public network.
