Service (eMLPP) within the digital cellular telecommunications system.
The contents of this ETS is subject to continuing work within TC-SMG and may change following formal
TC-SMG approval. Should TC-SMG modify the contents of this ETS, it will be resubmitted for OAP by
ETSI with an identifying change of release date and an increase in version number as follows:
Version 5.x.y
where:
y the third digit is incremented when editorial only changes have been incorporated in the
specification;
x the second digit is incremented for all other types of changes, i.e. technical enhancements,
corrections, updates, etc.

1 Scope
This European Telecommunication Standard (ETS) specifies the procedures used at the radio interface
(Reference point Um as defined in GSM 04.02) for normal operation, invocation, registration and
interrogation of the enhanced Multi-Level Precedence and Pre-emption Service (eMLPP) supplementary
service. Provision and withdrawal of supplementary services is an administrative matter between the
mobile subscriber and the service provider and cause no signalling on the radio interface.
In GSM 04.10 the general aspects of the specification of supplementary services at the layer 3 radio
interface are given.
GSM 04.80 specifies the formats and coding for the supplementary services.
Definitions and descriptions of supplementary services are given in GSM 02.04 and GSM 02.8x and
02.9x-series. GSM 02.67 is related specially to eMLPP.
Technical realization of supplementary services is described in GSM 03.11 and GSM 03.8x and
03.9x-series.
GSM 03.67 is related specially to eMLPP.
The procedures for Call Control, Mobility Management and Radio Resource management at the layer 3
radio interface are defined in GSM 04.07 and GSM 04.08.

NOTE: In the call related messages only the additional information for the eMLPP
supplementary service is shown in the figures.
4.1.1 Mobile originated calls
The mobile station can indicate the priority of each call initiated. If no priority is indicated by the user or a
non-compatible mobile station is used then the default priority level shall be applied which is stored in the
VLR. The selection of priority shall be an MMI function.
For mobile originated calls, the corresponding message flows are shown in figure 1.
