ETSI ETSI TR 125 931 V14.0.0 (2017-04)73GPP TR 25.931 version 14.0.0 Release 141 Scope 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 U
18、TRAN nodes and the CN to perform system functions. This gives an overall understanding of how the UTRAN works in example scenarios. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document.

40、estrial Radio Access Network 3.3 Notation for the signalling procedures Complex signalling procedures may involve several protocols in different nodes. In order to facilitate the understanding of these procedures, the following rules in the drawing of Message Sequence Chart (MSC) are applied: Messag
41、es are always exchanged between nodes, i.e. the sender and the receiver of a message are nodes and not single protocol entities; The protocol entity inside a node that is sending/receiving a message is represented by means of an ellipse, containing the protocol entity name; Each message is numbered,
42、 so that a numbered list with explanations can be added below the figure; Message parameters may be specified as shown in Figure 1 only when required for a clear understanding of the procedures; Explicit signalling is represented by means of continuous arrows; Inband signalling is represented by mea
43、ns of dotted arrows; A description of the relevant actions may be included as shown in Figure 1; The Setup and Release of Iub/Iur and Iu Data Transport Bearer with the ALCAP protocol is represented as shown in Figure 1; ETSI ETSI TR 125 931 V14.0.0 (2017-04)113GPP TR 25.931 version 14.0.0 Release 14
