The present document defines the stage 2 specifications of the Supplementary Service Pre-emptive Priority Call
(SS-PPC) for the TErrestrial Trunked Radio (TETRA).
SS-PPC enables a user to have preferential access to the network resources in a TETRA system in times of congestion
including pre-emption of calls. SS-PPC is applicable for pre-emptive priorities including the emergency priority.
SS-PPC includes the capability to pre-empt resources needed for higher priority calls and the capability to pre-empt
users from ongoing calls in order to move them to higher priority calls. SS-PPC specifies the definition, activation,
deactivation and interrogation for the usage of pre-emptive call priorities in the TETRA system. The Switching and
Management Infrastructure (SwMI) applies the SS-PPC priorities when it allocates the resources for calls. The SS-PPC
operations are defined for the SwMI and for the Mobile Station (MS).
SS-PPC is defined to subscribers of one TETRA system, but the subscribers may be located in several TETRA systems
and the information flows may be delivered over the Inter-System Interface (ISI). SS-PPC also is invoked for calls
within one TETRA system or for calls that extend over ISI to several TETRA systems.
Man-Machine Interface (MMI) and charging principles are outside the scope of the present document.
Stage 2 describes the functional capabilities of the Supplementary Service introduced in stage 1 description. Stage 2
identifies the functional capabilities for the management and operation of the service in the SwMI and in the MS.
Stage 2 describes also the information flows exchanged between these entities and the flows sent over the ISI.
NOTE: The stage 2 description is followed by the stage 3 description, which specifies the encoding rules for the
information flows and process behaviour for the different entities in the SwMI and in the MS.
