Method and Apparatus for Maintaining a Virtual Active Set Including a Closed Subscriber Group Cell

摘要

A method, apparatus and computer program product are provided that establishes a virtual active set including a first closed subscriber group (CSG) cell. At least one measured result of each of the first CSG cell and a second CSG cell is measured and the virtual active set is updated by replacing the first CSG cell with the second CSG cell in response to at least one measured result of the second CSG cell having a predefined relationship to the at least one measured result of the first CSG cell for a time to trigger. In regards to updating the virtual active set, the first CSG cell may be replaced with the second CSG cell in response to the at least one measured result of the second CSG cell having a predefined relationship to the at least one measured result of the first CSG cell by at least a predetermined amount for the time to trigger.
