Abstract
Provided are a secondary cell management method, a DU, a CU, and a base station. The method includes: acquiring, by a first network element, first trigger information; and managing, by the first network element, a secondary cell (Scell) for a user equipment (UE) according to the first trigger information.
Claims18
A secondary cell management method, comprising:
- acquiring, by a first network element, trigger information;
- and
- managing, by the first network element, a secondary cell (SCell) for a user equipment (UE) according to the trigger information;
- wherein the acquiring, by the first network element, the trigger information comprises:
- receiving, by the first network element, feedback sent by a second network element, wherein the feedback comprises the second network element refuses a change request sent by the first network element for changing a cell under the second network element to a first SCell;
- wherein the managing, by the first network element, the secondary cell for the UE according to the trigger information comprises:
- deciding, by the first network element, a SCell change according to the feedback;
- and
- wherein the first network element comprises a centralized unit, the second network element comprises a distributed unit.
A base station, comprising a first network element and a second network element, wherein the first network element comprises a first processor and a first memory storing an instruction executable by the first processor, and the second network element comprises a second processor and a second memory storing an instruction executable by the second processor;
- wherein the first processor is configured to acquire a first measurement report of a user equipment (UE), and add a secondary cell (SCell) to the UE according to the first measurement report, wherein the first measurement report is used for indicating that network quality of the UE satisfies a first preset condition;
- wherein the first processor is configured to receive feedback sent by the second processor, wherein the feedback comprises the second network element refuses a change request sent by the first processor for changing a cell under the second network element to a first SCell;
- wherein the first processor is configured to decide a SCell change according to the feedback;
- and
- wherein the first network element comprises a centralized unit, the second network element comprises a distributed unit.
A secondary cell management method, comprising:
- performing, by a first network element, management on a secondary cell (SCell) under a second network element through a first interface message;
- and
- wherein the management on the SCell comprises:
- requesting, by the first network element, to change the SCell at the second network element;
- wherein the requesting, by the first network element, to change the SCell at the second network element comprises:
- sending, by the first network element, a change request for requesting to change a cell under the second network element to a first SCell to the second network element;
- and
- in response to the second network element refuses the change request, deciding, by the first network element, a SCell change;
- and
- wherein the first network element comprises a centralized unit, the second network element comprises a distributed unit.
