Abstract

Provided are a method for indicating validity of System Information (SI), a network device, a terminal device and a computer storage medium. The method includes that: at least one validity indication for at least one SI Block (SIB) is configured; and the validity indication for an SIB to be reacquired is transmitted to a terminal device.

Claims

1. A method for indicating validity of System Information (SI), applied to a network device and comprising:

configuring a validity indication for at least one SI Block (SIB); and

transmitting the validity indication for an SIB to be reacquired to a terminal device.

2. The method of claim 1, wherein transmitting the validity indication for the SIB to be reacquired to the terminal device further comprises:

placing the validity indication for the SIB to be reacquired in Minimum SI (MSI) in a centralized or distributed or broadcast manner; and

transmitting the validity indication for the SIB to the terminal device.

3. The method of claim 2, further comprising:

placing the validity indication for the SIB to be reacquired in SIB 1 in the MSI in the centralized manner.

4. The method of claim 1, wherein configuring the validity indication for the at least one SIB further comprises:

configuring one validity indication for each of the at least one SIB other than the SIB 1 respectively.

5. The method of claim 1, wherein configuring the validity indication for the at least one SIB further comprises:

selecting at least part of SIBs from the at least one SIB other than SIB 1; and

configuring a same validity indication for the at least part of SIBs.

7. The method of claim 5, wherein selecting the at least part of SIBs from the at least one SIB other than the SIB 1 comprises:

selecting at least part of SIBs having at least one of a same function and a same service type from the at least one SIB other than the SIB 1, or

selecting at least part of SIBs placed in a same system message from the at least one SIB other than the SIB 1.

8. The method of claim 1, further comprising:

transmitting validity indications configured for all SIBs to the terminal device.

26. The method of claim 1, wherein one validity indication corresponds to one SIB or multiple SIBs.

6. (canceled)

9. A method for indicating validity of System Information (SI), applied to a terminal device and comprising:

detecting a validity indication, transmitted by a network side, for a SI Block (SIB) to be reacquired, the validity indication being for at least one SIB; and

reacquiring the SIB based on the validity indication.

10. The method of claim 9, further comprising:

acquiring validity indications configured for all SIBs from the network side.

11. The method of claim 9, further comprising:

detecting the validity indication for the SIB to be reacquired from Minimum SI (MSI).

20. A terminal device, comprising:

a processor, and

a memory configured to store a computer program capable of running in the processor, wherein the processor is configured to run the computer program to execute operations of the method for indicating validity of System Information (SI) of claim 9.

21. The terminal device of claim 20, wherein the processor is further configured to run the computer program to execute an operation of:

controlling a transceiver to acquire validity indications configured for all SIBs from the network side.

22. The terminal device of claim 21, wherein the processor is further configured to run the computer program to execute an operation of:

detecting the validity indication for the SIB to be reacquired from Minimum SI (MSI).

12. A network device, comprising:

a processor, configured to configure a validity indication for at least one System Information Block (SIB); and

a network interface, coupled with the processor and configured to transmit the validity indication for an SIB to be reacquired to a terminal device.

13. The network device of claim 12, wherein the processor is configured to place the validity indication for the SIB to be reacquired in Minimum SI (MSI) in a centralized or distributed or broadcast manner.

14. The network device of claim 13, wherein the processor is configured to place the validity indication for the SIB to be reacquired in SIB 1 in the MSI in the centralized manner.

15. The network device of claim 12, wherein the processor is configured to configure one validity indication for each of the at least one SIB other than the SIB 1 respectively.

16. The network device of claim 12, wherein the processor is configured to:

select at least part of SIBs from the at least one SIB other than SIB 1; and

configure a same validity indication for the at least part of SIBs;

wherein the processor is further configured to;

select at least part of SIBs placed in a same system message from the at least one SIB other than the SIB 1;

or

select at least part of SIBs having at least one of a same function and a same service type from the at least one SIB other than the SIB 1.

19. The network device of claim 12, wherein the processor is configured to transmit, through the network interface, validity indications for all SIBs to the terminal device.
