Unico’s deep knowledge of networks, telephony, provisioning and billing systems allowed Unico to devise a smart solution that would meet the stringent migration requirements.
The initial challenge was to extract all data from the old platform and migrate it to the new platform, then update the relevant network elements so that future calls would be managed by the new platform. If a call was in progress while the transfer was being undertaken, the transferred balance would be incorrect on the new system.
Unico devised a method which guaranteed correct transfer by checking that calls were not in progress, setting the network so that no calls were possible, transferring, and then reinstating calling capability using the new platform. For only 3 seconds the customers were unable to make a call. Problem solved!
It became apparent, however that there was a further problem; the new platform only had limited capacity to take on new subscribers, making it necessary to throttle the transfer process. To ensure the new system was not overwhelmed with data, whilst still meeting the time frame to avoid cost penalties, Unico developed a system to trap inter-system messages and control the flow of migration.
