UMTS Protocols and signalling procedures

Course Description

UMTS Protocols and Signalling Procedures is designed to provide a thorough understanding of  UTRAN functionality and operations. The nodes and different interfaces used by UTRAN to communicate over, the protocols used for signalling purposes and data transfer are described with the focus set on the air interface and Radio Network Layer Protocols. Traffic cases are used in order to analyse the procedures supported by UTRAN for paging, connection establishment, handover etc.
