| 释义 |
International premium rate service (IPRS) refers to internationally available telephone-based premium services. It is analogous to "900" or "976" numbers in North America, which always incur a recipient-defined charge in excess of regular call charges. Internationally, this service has been allocated country code +979. IPRS numbers are known as UIPRNs. The ITU recommendation for IPRS defines four charge categories, across which the +979 numbering space is divided:
UIPRNs are only available to premium service providers who will provide their service to more than one country. The format of the numbers will be 979 a bcdefghi, where the a digit, 1, 3, 5 or 9, will indicate the charging band, and the remaining digits will be the IPRS subscriber's number. 1, 3 and 5 indicate charge bands 1, 2 and 3, respectively, while 9 will indicate a special charge band. The service is not yet known to be active{{Citation needed|date=March 2014}}. Once it is activated, it may not be available from every country{{Citation needed|date=March 2014}}, even though there is minimal or no cost to the receiving customer, as interchange rates would need to be negotiated for countries to allow origination of calls.
