Abstract
The invention relates to the generation of configuration data for use in the migration of telephone switching systems. Configuration data for use in the migration of subscribers from a first telephone switching system over to a second telephone switching system in a telecommunications network is generated by monitoring signaling information on telephone channels associated with subscribers for telephone calls conducted via the first telephone switching system. The monitored signaling information is then analyzed in relation to call data produced by the first telephone switching system for the calls to identify relationships between the monitored signaling information and call data for calls conducted by subscribers. Configuration data based on the identified relationships is then stored and used to configure the second telephone switching system with mappings between the associated telephone channels and the telephone dialing numbers for subscribers.
