EDGE Architectures & Interfaces

EDGE Outdoor Base Station

User Plane Protocols (Not much changes!)

•The protocols that are influenced by the introduction of EDGE are shaded.

•The protocols closest to the physical layer (the radio link control and

mobile allocation channel) are most affected by EDGE (GSM 04.60).

•There also are some minor modifications to the base station system

GPRS protocol. Apart from these changes,the rest of the protocol stack

remains intact after the introduction of EDGE.
