DS TS 144 018 V14.4.0:2018

Digital cellular telecommunications system (Phase 2+) (GSM); Mobile radio interface layer 3 specification; GSM/EDGE Radio Resource Control (RRC) protocol (3GPP TS 44.018 version 14.4.0 Release 14)

Scope

The present document specifies the procedures used at the radio interface (Reference Point Um, see 3GPP TS 24.002)
for Radio Resource (RR) management.
Notation "Reserved sub-clause number" is used to indicate which sub-clauses of the specification were moved from this
part of the standard to the other part when this standard was split between RAN and CN parts.
When the notations for "further study" or "FS" or "FFS" are present in this specification they mean that the indicated
text is not a normative portion of this standard.
These procedures are defined in terms of messages exchanged over the control channels of the radio interface. The
control channels are described in 3GPP TS 44.003.
The structured functions and procedures of this protocol and the relationship with other layers and entities are described
in general terms in 3GPP TS 24.007.
