Patent ID: 6985738

Claim:
Method for implementing channel changes from a current plan to a new predetermined plan in a cellular network comprising a plurality of cells, each cell corresponding to at least one equipment, to which a channel may be allocated for communicating signals to and from mobile end stations in the cell; each equipment in the network being adapted for receiving channel change information; blocking operation; performing a channel change according to the predetermined new channel plan and enabling operation; the method comprising the steps of initially selecting at least one start cell in the cellular network; defining a first group of cells ( 1 ) comprising only the start cell(s) ( 12 ), blocking equipment that shall be changed in the first group of cells ( 13 ), performing a sub-routine carrying out the following steps: identifying a second group of cells ( 2 ) not identified previously and having a cell border being adjacent the first group of cells ( 1 , 14 ), blocking equipment that shall be changed in the second group of cells ( 2 , 15 ) while performing changes from the current cell plan to the new cell plan on equipment in the first group of cells ( 1 , 16 ), enabling the first group of cells ( 1 , 17 ), repeating this procedure with a new first group of cells being equal to the second group of cells ( 1 := 2 ) until all cells have been changed ( 18 , 19 ).
