Digital cellular telecommunications system (Phase 2+) (GSM); enhanced Multi-Level Precedence and Pre-emption service (eMLPP); Stage 3 (GSM 04.67 version 5.0.1)

This European Telecommunication Standard (ETS) specifies the procedure s 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 serv ices 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 servi ces. Definitions and descriptions of supplementary services are given in GS M 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 Resourc e management at the layer 3 radio interface are defined in GSM 04.07 a nd GSM 04.08.

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.
