universal personal telecommunications (UPT)

Universal PersonalTelecommunications (UPT) is a standardized service of fixed and mobile networks that provides the subscriber with worldwide mobility, independent of the respective network operator. The service code

is valid worldwide and is assigned a personal service profile. In contrast to number portability

, wherethe subscriber can keep his number

when switching to another network operator, the subscriber to the UPT service receives a number that differs significantly from his original number, which is embedded in thecountry code

. TheUPT service is implemented in the intelligent network (IN) and supports the worldwide mobility of the subscriber, who can be reached everywhere under a uniform number. In addition, all call charges can be billed via the UPT account and authentications can be implemented independent of the operator. The UPT user can configure his own service profiles. Each UPT service profile belongs to a UPT number. In

1996, the International Telecommunication Union (ITU-T) defined the service code (0)878 for the UPT service. This service code can be used to obtain a uniform call number worldwide.
