Cell management method and apparatus, device and storage medium
A cell management method and apparatus, a device and a non-transitory computer-readable storage medium are disclosed. The method may include: sending a first dual-connection control message to a second communication node, where the first dual-connection control message is used for instructing the second communication node to manage related information of a conditional candidate target PSCell; and receiving the related information of the conditional candidate target PSCell sent by the second communication node.
1. A cell management method, which is applied to a first communication node, comprising:
sending a first dual connection control message comprising a first pre-configuration message to a second communication node, wherein the first dual connection control message is used to instruct the second communication node to manage relevant information of a conditional candidate target primary secondary cell (PSCell); and
receiving the relevant information of the conditional candidate target PSCell sent by the second communication node;
wherein the first pre-configuration message is used to limit a pre-configured maximum number of conditional candidate target PSCells within the second communication node in service.
2. The method of claim 1 , wherein the first dual connection control message further comprises a query message, or a release message.
3. The method of claim 2 , wherein sending the first dual connection control message to the second communication node comprises:
sending a query message to the second communication node, wherein the query message is used to the query relevant information of the conditional candidate target PSCell in the second communication node in service.
4. The method of claim 3 , wherein the relevant information of the conditional candidate target PSCell comprises at least one of:
a cell global identifier (CGI) of the conditional candidate target PSCell;
a cell carrier frequency of the conditional candidate target PSCell;
a bandwidth of the conditional candidate target PSCell;
a physical cell identifier (PCI) of the conditional candidate target PSCell;
a total number of the conditional candidate target PSCells allowed on a plurality of carrier frequencies; and
a total number of the conditional candidate target PSCells pre-configured and allowed in the second communication node.
5. The method of claim 2 , wherein the relevant information of the conditional candidate target PSCell comprises:
attribute class indication information of the conditional candidate target PSCell.
6. The method of claim 5 , wherein the attribute class indication information refers to an attribute class indication indicating whether the conditional candidate target PSCell can be applied for release, cancellation or deletion by the first communication node.
7. The method of claim 2 , wherein sending the first dual connection control message to the second communication node comprises:
sending a first release message to the second communication node, wherein the first release message is used to instruct the second communication node to release, delete or cancel at least one conditional candidate target PSCell designated in the second communication node in service.
8. The method of claim 7 , wherein the conditional candidate target PSCell to be released, deleted or cancelled is indicated by at least one of the following information:
a CGI of the conditional candidate target PSCell;
a cell carrier frequency of the conditional candidate target PSCell;
a bandwidth of the conditional candidate target PSCell;
a PCI of the conditional candidate target PSCell; and
a number of conditional candidate target PSCells in the second communication node to be released, deleted or cancelled by the second communication node.
9. The method of claim 1 , wherein the first dual connection control message is carried by a secondary node addition request signaling, or the first dual connection control message is carried by a secondary node modification request signaling.
10. The method of claim 1 , wherein:
the maximum number is the maximum total number of the conditional candidate target PSCells of the second communication node at all carrier frequencies; or
in response to the second communication node being a second communication node of a secondary node (SN), the maximum number is the maximum number of the conditional candidate target PSCells of the second communication node of the SN at a carrier frequency.
11. The method of claim 1 , wherein the second communication node is prohibited from locally pre-configuring the conditional candidate target PSCell in response to the maximum number being a preset value.
12. A device, comprising:
at least one processor; and
a memory, configured to store at least one program;
wherein the at least one program, when executed by the at least one processor, causes the at least one processor to carry out the cell management method of claim 1 .
13. A non-transitory computer-readable storage medium storing a computer program which, when executed by a processor, causes the processor to carry out the cell management method of claim 1 .
14. A cell management method, which is applied to a second communication node, comprising:
sending a second dual connection control message comprising a second pre-configuration message to a first communication node, wherein the second dual connection control message is used to apply for relevant information of a conditional candidate target primary secondary cell (PSCell) from the first communication node, or the second dual connection control message is used to send relevant information of a conditional candidate target primary secondary cell (PSCell) to the first communication node;
wherein the second pre-configuration message is used for applying for a pre-configured maximum number of the conditional candidate target PSCells within the second communication node in service from the first communication node.
15. The method of claim 14 , wherein the second dual connection control message further comprises a notification message or a release message.
16. The method of claim 15 , wherein sending the second dual connection control message to the first communication node comprises:
actively sending a notification message to the first communication node, wherein the notification message is used to actively inform the first communication node of relevant information of the conditional candidate target PSCell within the second communication node in service;
or
sending a second release message to the first communication node, wherein the second release message is used to inform the first communication node of relevant resources of at least one conditional candidate target PSCell to be released, deleted or cancelled which is designated in the second communication node in service.
17. The method of claim 14 , wherein the second dual connection control message is carried by a secondary node modification request signaling.
18. A device, comprising:
at least one processor; and
a memory, configured to store at least one program;
wherein the at least one program, when executed by the at least one processor, causes the at least one processor to carry out the cell management method of claim 14 .
19. A non-transitory computer-readable storage medium storing a computer program which, when executed by a processor, causes the processor to carry out the cell management method of claim 14 .
