1 Scope
The present document defines the stage 2 service description for a Generic Access Network (GAN) . It describes the
GAN system concepts, documents the reference architecture, functional entities, network interfaces, and high-level
procedures.
GAN supports two modes of operation:
• GAN A/Gb mode
• GAN Iu mode
GAN A/Gb mode supports an extension of GSM/GPRS mobile services that is achieved by tunnelling Non Access
Stratum (NAS) protocols between the MS and the Core Network over an IP network and the A and Gb interfaces to the
MSC and SGSN, respectively.
GAN Iu mode supports an extension of UMTS mobile services that is achieved by tunnelling Non Access Stratum
(NAS) protocols between the user equipment (MS) and the Core Network over an IP network and the Iu-cs and Iu-ps
interfaces to the MSC and SGSN, respectively.
Both GAN modes are complements to traditional GERAN/UTRAN/E-UTRAN radio access network coverage.
