PRIMARY SECONDARY CELL CHANGE METHOD AND BASE STATION

摘要

Embodiments of the present invention disclose a primary secondary cell change method and a base station. The primary secondary cell change method in the embodiments of the present invention includes: determining, by a primary base station, to change a first primary secondary cell served by a secondary base station, and selecting a second primary secondary cell from cells served by the secondary base station; sending, by the primary base station, a first message to the secondary base station, which is used to request the secondary base station to change the primary secondary cell, where the first message includes an identity of the second primary secondary cell; and sending, by the primary base station, a second message to a user equipment UE, which is used to request the UE to use the second primary secondary cell.

主权项

1. A primary secondary cell change method, comprising:
determining, by a secondary base station, to change a first primary secondary cell applicable as a primary secondary cell served by the secondary base station; selecting, by the secondary base station, a second primary secondary cell from cells served by the secondary base station; sending, by the secondary base station, a first message to a primary base station, which is used to indicate change of the primary secondary cell, wherein the first message comprises an identity of the second primary secondary cell which is applicable as a updated primary secondary cell served by the secondary base station; wherein cells, being separately served by the primary base station and the secondary base station, simultaneously supply service to a user equipment (UE), the cells served by the primary base station comprise a primary cell, and the cells served by the secondary base station comprise either the primary secondary cell or the updated primary secondary cell.
