GERAN（GSM EDGE Radio Access Network）是 GSM／EDGE 无线通信网络（Radio Access Network）的缩写，是GSM/EDGE的无线接入部分。GERAN 由 3GPP（Third Generation Partnership Project）主导。GERAN 是GSM的关键技术之一，并与UMTS/GSM结合。

GERAN 是GSM/EDGE的无线接入部分，包括基地台（base stations）和基地台控制器（base station controllers）以及各种接口（如Ater、Abis、A 等）

GERAN is an abbreviation for GSM EDGE Radio Access Network. The standards for GERAN are maintained by the 3GPP (Third Generation Partnership Project). GERAN is a key part of GSM, and also of combined UMTS/GSM networks.

GERAN is the radio part of GSM/EDGE together with the network that joins the base stations (the Ater and Abis interfaces) and the base station controllers (A interfaces, etc.) The network represents the core of a GSM network, through which phone calls and packet data are routed from and to the PSTN and Internet to and from subscriber handsets. A mobile phone operator's network comprises one or more GERANs, coupled with UTRANs in the case of a UMTS/GSM network.
