Portability of mobile phone numbers: the new system for managing the portability of mobile telephone numbers available since 21 May 2007 has been a total success
05/07/2007
The GIE EGP called upon Steria in April 2006 to develop and set up the central system on the one hand and take on the co-ordination of test campaigns between operators on the other hand. Steria is now responsible for operating the system.

Mobile telephone operators grouped together under the GIE EGP (Economic Interest Grouping Portability Management Entity) successfully launched on 21 May 2007 the central system for the management of mobile phone number portability.

This technical system is connected up with the IT systems of the following operators: Auchan Telecom, Bouygues Telecom, Carrefour Mobile, Coriolis Telecom, Debitel, Futur Telecom, Neuf Mobile, NRJ Mobile, Orange France, Omer Telecom (Breizh Mobile, Virgin Mobile), SFR, and Tele2. It makes it possible to transmit and process the exchange of data required to manage requests from subscribers who wish to change operator and keep the same telephone number. Three new operators (Mobisud, Ten and Transatel) will be connected by the end of the year.

This system was necessary to fulfil the regulatory obligations with regard to good conditions of safety and reliability to provide the portability of the telephone number in less than ten days and ensure a one-stop shop. The subscriber therefore only has to contact the new operator which will deal with the necessary formalities with the previous operator.

Since this service was set up, the system has dealt effectively with more than 110,000 portability request.

This system was particularly complex to set up. A central system had to be set up and operated by the GIE EGP, and for each of the operators, to carry out developments of the IT system to adapt it to the new processes. Almost 6 months of tests were necessary with all the systems connected to each other to finalise the entire structure. All systems had to be started up at the same time without interrupting the previous system that had been operating up to June 2003 until the new service was put into operation.

The GIE EGP called upon Steria in April 2006 to develop and set up the central system on the one hand and take on the co-ordination of test campaigns between operators on the other hand. Steria is now responsible for operating the system.

This project is the most complex to be run in Europe to date in terms of the number of operators connected, the process of the one-stop-shop and the short periods to set it up.

Almost 300 people took part directly in this project. The expertise provided by Steria to rollout the appropriate technical architecture and manage the test campaigns, the work of the technical teams of the operators and the efforts to ensuring that the deadlines are adhered have made it possible to take the step successfully for the benefit of the consumer and to ensure the fluidity of the competitive market.
