Universal Personal Telecommunications
Universal Personal Telecommunications
Universal personal telecommunications (UPT) is a special segment of the international telephone number space which has been set aside for universal personal telephone numbers. This service has been allocated country code +87810 and is completed by a 10-digit subscriber number which provides 10 billion unique numbers. The International Telecommunication Union (ITU) introduced this concept in 2001, referring to it as "global number portability". However, number portability normally refers to the service of keeping an existing phone number after moving service to another provider. The delegation of UPT was requested by VisionNG Chairman Herwart Wermescher and was confirmed by Counsellor, SG2 of ITU-TSB Richard Hill on May 21, 2002.
The UPT service
The UPT standards have been developed to allow a UPT number to be associated with any device on any network, anywhere in the world. An individual should be able to enter an access code to make or receive calls on any device and can be provisioned as a global mobile telephone number. UPT allows ad hoc sharing of physical devices and is intended to be independent of geography or network provider. From the +87810 numbering space, operators can offer their customers next generation services - voice, data, email, SMS, web and location-based services - using a single "number for life" that transcends national boundaries and traditional ways of thinking about communications.
Initially, UPT number blocks were allocated to VoIP or Next Generation networks but as technology has advanced UPT is more and more been seen as a numbering and addressing solution for Digital Identity and Internet of Things marketplace.
In February 2016, the ITU approved the assignment of a Mobile Country Code and Network Code associated to the UPT Country Code. This allows for the provision of 10 billion unique IMSI’s for the deployment of Global Mobile Services.
UPT service profile
The UPT service profile is a record that contains all information related to a UPT user, which information is required to provide that user with UPT service such as subscriptions to basic and supplementing services and call-routing preferences. Each UPT service profile is associated with a single UPT number. A Name Authority Pointer (NAPTR) is a type of resource record in the Domain Name System of the Internet. NAPTR records are most commonly used for applications in Internet telephony, for example, in the mapping of servers and user addresses in the Session Initiation Protocol (SIP). The combination of NAPTR records with Service Records (SRV) allows the chaining of multiple records to form complex rewrite rules which produce new domain labels or uniform resource identifiers (URIs).
The UPT number uniquely identifies a UPT user and is used to place a call to, or to forward a call to, that user. A user may have multiple UPT numbers (such as a business UPT number for business calls and a private UPT number for private calls). In the case of multiple numbers, each UPT number is considered, from a network vantage point, to identify a distinct UPT user, even if all such numbers identify the same person or entity. A single 87810 number simply and securely connects all your online identities – anywhere in the world, at any time, on any device. UPT is an enabling solution providing one number for life and for multiple devices and services. It is a global range delegated by the ITU and comprises 10 billion enum-enabled numbers with the prefix 87810 followed by a 10 digit subscriber number. It is in Tier 1 ENUM DNS registry under 0.1.8.7.8.e164.arpa
UPT environment is the environment within which the UPT service facilities are offered, consisting of combinations of global fixed, mobile and Next Generation networks.
