摘要

A communication system having a plurality of service control points which can be mutually coupled and are assigned to at least one service switching point for executing services, a database system, and a service management system for managing the services. To enhance the availability of the database system, this database system comprises distributed databases which have each a database control point. At least several databases are provided for storing copies of logically coherent partitions of the total database. To execute a database operation, a copy of a partition and the database control point that manages that partition are located by reading a Table.
