Scope

This European Telecommunication Standard (ETS) defines the principal architecture of layer 3 and its sublayers on the GSM Um interface, i.e. the interface between Mobile Station (MS) and network; for the CM sublayer, the description is restricted to paradigmatic examples, call control, supplementary services, and short message services. It also defines the basic message format and error handling applied by the layer 3 protocols.
