METHOD AND DEVICE AT CELLULAR TELECOMMUNICATION SYSTEM

摘要

In a cellular telecommunication system one and the same mobile unit can be connected to two or more base stations, which implies that the system operates with macro diversity. Respective concerned mobile unit operates with an active set-function or a connection pattern which indicates and estimates the mobile unit's connection situation in relation to concerned base stations, and decides about changes in the connection situation. In the system the mentioned active set is predicted adaptively by means of previously obtained data or parameters. By the invention are achieved improved system functions at which can be mentioned safe handover-function, better transmission quality in the border areas of the cells, etc.
