Abstract
The present application discloses a conditional handover (CHO) processing method and apparatus, a related device, and a storage medium. The method comprises: a first network device determining that CHO configuration information is invalid and indicating to a terminal that the CHO configuration information is invalid.
Claims17
A method for Conditional HandOver (CHO)-based processing, applied to a first network device, and the method comprising:
- determining information of invalid CHO configuration;
- and
- indicating the information of invalid CHO configuration to a terminal,
- wherein an indication manner comprises at least one of:
- information of one or more invalid frequencies;
- or
- a related identity of an invalid cell;
- wherein the CHO configuration comprises an identity relevant to a target cell and an event that triggers HandOver (HO),
- wherein the CHO configuration is configured to cause the terminal to execute one of the following operations:
- determining to perform CHO, and performing the CHO by using a configured cell-level dedicated random access resource for CHO;
- and
- after the CHO configuration is received, starting a first timer, wherein after the first timer expires, at least one of a configured condition is invalid, or a random access resource, configured for CHO of the terminal, of at least one candidate second network device for the HO is releasable.
A method for Conditional HandOver (CHO)-based processing, applied to a terminal, and the method comprising:
- receiving information of invalid CHO configuration indicated by a first network device;
- and
- updating information of local CHO configuration with the information of the indicated invalid CHO configuration,
- wherein a manner of indication comprises at least one of:
- information of one or more invalid frequencies;
- or
- a related identity of an invalid cell;
- wherein the CHO configuration comprises an identity relevant to a target cell and an event that triggers HandOver (HO),
- wherein the method further comprises executing one of the following operations based on configuration information of CHO:
- determining to perform CHO, and performing the CHO by using a configured cell-level dedicated random access resource for CHO;
- and
- after the configuration information of CHO is received, starting a first timer, wherein after the first timer expires, at least one of a configured condition is invalid, or a random access resource, configured for CHO of the terminal, of at least one candidate second network device for the HO is releasable.
A method for Conditional HandOver (CHO)-based processing, applied to a first network device, and the method comprising:
- determining information of invalid CHO configuration;
- and
- indicating the information of invalid CHO configuration to a terminal, wherein an indication manner comprises at least one of:
- information of one or more invalid frequencies;
- or
- a related identity of an invalid cell;
- wherein the method further comprises:
- sending priority information to at least one candidate second network device for HandOver (HO), the priority information being configured to indicate a priority at which the at least one candidate second network device serves the terminal,
- wherein the CHO configuration comprises an identity relevant to a target cell and an event that triggers the HO,
- wherein the first network device presently provides service for the terminal,
- wherein sending the priority information to the at least one candidate second network device for the HO comprises:
- sending a HO request message to the at least one candidate second network device, the HO request message containing the priority information.
