Method and a system for enabling a mobile terminal to continue to be served by a home base station

摘要

The present invention concerns a method for enabling a mobile terminal to continue to be served by a home base station when the mobile terminal is in the coverage area of the serving home base station and the coverage area of the serving home base station starts superposing with the coverage area of another home base station having the same physical cell identity and being synchronized with the serving home base station, each home base station broadcasting the physical cell identifier in its coverage area. The method comprises the steps of :
- determining that the coverage areas start superposing,
- determining at least one timing offset to be applied at a predetermined moment by at least one of the home base stations for transferring signals in its cell,
- transmitting to the mobile terminal the at least one timing offset and the moment,
- applying the at least one timing offset at the moment.
