Time tariff
In telecommunications , the term time tariff refers to billing based on the duration of the connection.
Time tariffs are the predominant form of billing, particularly for circuit-switched technology ( telephone calls in traditional landline and cellular networks, as well as narrow-band dial -up internet connections - including CSD in cellular networks ), but are also used outside of this (e.g. for billing DSL and UMTS ).
Time tariffs are usually clocked at intervals ; mostly seconds or minutes; some providers also charge a connection fee.
Other types of billing are flat-rate tariffs with a fixed monthly fee or a flat-rate price per connection, regardless of the duration, and the volume tariff , which for digital connections is based on the amount of data transferred.
