UMTS Layers, Interfaces, Protocols - General

Previous post was a short introduction for general information regarding layers, protocols, interfaces and planes.
In UMTS one can find all mentioned objects and divisions.

As for the layers the Figure 1 shows what layers are defined for UMTS.

As mentioned in each layer may have its User and Control Plane. Each layer has dedicated protocol to work in proper plane. Detailed description of theses protocols will be placed in next posts.

Signaling bearers for Transport Network User Plane and for Transport Network Control Plane may be different but may be the same. It is up to configuration if the same Signaling Bearers would be used [2]
