Abstract
The present invention discloses a method and an apparatus for a virtual base station migration in a BBU pool which has multiple baseband units. The migration method comprises the following steps performed by a first virtual base station: measuring an available bandwidth between the first virtual base station and a second virtual base station, wherein the first virtual base station and the second virtual base station belong to different baseband units in the BBU pool; estimating a service interruption time of the first virtual base station; selecting a migration mechanism of the first virtual base station according to the estimated service interruption time. The migration mechanism comprises configuring a common measurement gap for user devices of the first virtual base station, or configuring random access time slots for user devices of the first virtual base station, or configuring a discontinuous receiving cycle for user devices of the first virtual base station. The solution of the present invention enables user devices in a connected state not to be influenced by a migration during the service interruption and achieve a lossless migration between virtual base stations.
