The invention relates to a method and data structure for controlling switching centers (1, 14, 17, 19, 21, 23, 25, 27). According to the invention switching centers (1, 14, 17, 19, 21, 23, 25, 27) are controlled to update the control information stored in the semipermanent databases of said switching centers (1, 14, 17, 19, 21, 23, 25, 27) with information retrieved from service database (5) and the update operation of said semipermanent databases of said switching centers (1, 14, 17, 19, 21, 23, 25, 27) is chained so that selected switching centers (1, 14, 17, 19, 21, 23, 25, 27) of desired telecommunications networks are arranged to perform sequentially the updating of their control information with information retrieved from said service database (5). |
