Universal Mobile Telecommunications System (UMTS); UTRAN functions, examples on signalling procedures
|Publication Date:||1 August 2020|
The present document describes the UTRAN functions by means of signalling procedure examples (Message Sequence Charts). The signalling procedure examples show the interaction between the UE, the different UTRAN nodes and the CN to perform system functions. This gives an overall understanding of how the UTRAN works in example scenarios.
