A METHOD AND A COMPUTER PROGRAM RELATED TO CELL ALLOCATION MANAGEMENT IN A MOBILE RADIO NETWORK

摘要

In mobile radio system supporting soft handover several cells that supports a dedicated radio channel with a mobile station are called the Active Set (AS). The mobile station measures the radio link quality of a set of cells called Monitored Set (Mos) and that are candidates for being included in the Active Set. If many cells are included in the Monitored Set the time to make a good measure of all cells will be long, and the time to perform handover will increase. However, the right cell need be is included in the Monitored Set to become included the Active Set. According to the present invention cells that have good radio properties in the mobile location area (ELA2) are selected for the Monitored Set and because this area is more restricted than the whole service area of the cells in the Active Set, a low number of cells need be included.
