Patent ID: 8208929

Claim:
A method of selecting a cell from a certain active set of cells to become serving cell for a mobile terminal instead of the primary cell of said active set of cells during a call in a mobile communications network implementing soft handover, the method comprising the steps of: determining whether the radio access bearer (RAB) of said call is being served on a soft handover area or not, and: if said call is being served on a soft handover area, determining whether the user of said mobile terminal can be considered static or in motion, and: if said user of said mobile terminal is considered static, comparing the load of said primary cell to the load of at least one of the remaining cells within the active set, and: if the load of said primary cell exceeds the load of said at least one of said remaining cells within the active set by a predetermined factor, transferring the downlink user plane from said primary cell to said cell of said remaining cells within the active set, which is less loaded than said primary cell; wherein said step of determining whether the radio access bearer (RAB) of said call is being served on a soft handover area or not, is done as follows: counting the number of cells forming said active set; if said active set is formed by more than one cell, checking whether said cells forming the active set belong to at least two different nodeBs; and if said cells forming the active set belong to at least two different nodeBs, it is determined that the radio access bearer (RAB) of said call is being served on a soft handover area.
