The present document specifies the Stage 1 description of High Speed Circuit Switched Data (HSCSD). HSCSD is a feature that introduce General Bearer Services and a multislot mechanism is used for user rates that can be achieved with one or more TCH/F. Multislot also defines a flexible use of air interface resources which makes efficient and flexible use of higher user rates feasible.
The Multislot mechanism is only applicable to GERAN.
At UTRAN radio access parameters used for GBS user data are specified at TS 23.107.
