Abstract:
A method for using data services of a first telecommunication system from a terminal (26) of a second telecommunication system by means of a base station (20) and a switching centre (1), comprising steps of:performing in the base station rate adaptations and mappings required for the conversions of data between the format of said first telecommunication system and the format of said second telecommunication system,wherein the first telecommunication system is a GSM system and the second telecommunication system is a DECT system, and whereinthe step of performing rate adaptations and mappings includes a step of performing rate adaptations RA2 and RA1 conforming to a CCITT V.110 standard, as well as a mapping between the RA1 rate adaptation and at least two separate parallel operating protocol entities of the DECT system, for a conversion of transmission rate between a transmission rate used between the switching centre and the base station and a lower synchronous transmission rate.
