GSM EDGE Radio Access Network (GERAN) is a radio access network architecture, based on GSM/EDGE radio access technologies. The GERAN is fully harmonised with the UMTS Terrestrial Radio Access Network (UTRAN) through a common connectivity to the UMTS core network. This makes it possible to build a combined network for GSM/GPRS and UMTS.

The GERAN is defined in UMTS Release 5.
