Carrier aggregation processing method and device

摘要

In the field of wireless communications technologies, a CA processing method and device, with a CA processing scheme, are applied to a network sharing scenario. A second cell is determined according to a first PLMN ID used by a CA user equipment in a first cell and a frequency supported by the CA user equipment, where the first cell is currently accessed by the CA UE, CA can be performed to aggregate a second PLMN ID supported by the second cell with the first PLMN ID used by the CA user equipment in the first cell, and a frequency used by the second cell can be supported by the CA user equipment. According to the determined second cell, a CA cell is configured for the CA user equipment.

1. A carrier aggregation processing method comprising:
determining, by a network-side device, a second cell through public land mobile network identifiers (PLMN IDs) screening according to a first PLMN ID used by a carrier aggregation (CA) user equipment in a first cell and through frequencies screening according to a frequency supported by the CA user equipment,
wherein the first cell is currently accessed by the CA user equipment, a PLMN ID supported by the second cell comprises the first PLMN ID, and a frequency used by the second cell can be supported by the CA user equipment, and wherein at least one cell of the first and second cells supports other PLMN ID besides the first PLMN ID; setting, by the network-side device, the second cell as a CA cell for the CA user equipment; wherein the determining, by the network-side device, a second cell, comprises: selecting, by the network-side device, non-accessing cells supporting the first PLMN ID from a first cell set comprising at least the first and second cells; and selecting, by the network-side device, from the selected non-accessing cells, a cell adopting the frequency that can be supported by the CA user equipment as the second cell.
