Terrestrial Trunked Radio (TETRA); Voice plus Data (V+D); Part 12: Supplementary services stage 3; Sub-part 10: Priority Call (PC)

The present document defines the stage 3 specifications of the Supplementary Service Priority Call (SS-PC) for the Terrestrial Trunked RAdio (TETRA). The SS-PC enables a user to have preferential access to the network resources in the TETRA system in times of congestion. The SS-PC applies for the basic services: circuit mode calls (speech or data). The SS-PC specifies the definition, activation, deactivation and interrogation for the usage of low and high call priorities in the TETRA system. The operations are defined for the Switching and Management Infrastructure (SwMI), for the Mobile Station (MS) and for the Line Station (LS). SS-PC can be defined to subscribers of one TETRA system, but the subscribers can be located in several TETRA systems and the information flows can be delivered over the Inter System Interface (ISI). SS-PC can also be invoked for basic services within one TETRA system or for basic services that extend over ISI to several TETRA systems.
The pre-emptive priorities are outside of the scope of the present document.
Man-Machine Interface (MMI) and Charging principles are outside the scope of the present document.
Supplementary Service stage 3 specification is preceded by the stage 1 and the stage 2 specifications of the service. Stage 1 describes the functional capabilities from the user's point of view. Stage 2 defines the functional behaviour in terms of Functional Entities (FEs) and information flows. Stage 3 gives a precise description of the Supplementary Service from the implementation point of view. It defines the protocol for the service and the encoding rules for the information flows. It defines the processes for the functional entities and their behaviour. The described protocols and behaviour apply to the SwMI, for the MS and for the LS and can be applied over the ISI between TETRA systems. Aspects relating to all supplementary services are detailed in EN 300 392-9 [2].

1 Scope
The present document defines the stage 3 specifications of the Supplementary Service Priority Call (SS-PC) for the
Terrestrial Trunked RAdio (TETRA).
The SS-PC enables a user to have preferential access to the network resources in the TETRA system in times of
congestion. The SS-PC applies for the basic services: circuit mode calls (speech or data). The SS-PC specifies the
definition, activation, deactivation and interrogation for the usage of low and high call priorities in the TETRA system.
The operations are defined for the Switching and Management Infrastructure (SwMI), for the Mobile Station (MS) and
for the Line Station (LS). SS-PC can be defined to subscribers of one TETRA system, but the subscribers can be located
in several TETRA systems and the information flows can be delivered over the Inter System Interface (ISI). SS-PC can
also be invoked for basic services within one TETRA system or for basic services that extend over ISI to several
TETRA systems.
The pre-emptive priorities are outside of the scope of the present document.
Man-Machine Interface (MMI) and Charging principles are outside the scope of the present document.
Supplementary Service stage 3 specification is preceded by the stage 1 and the stage 2 specifications of the service.
Stage 1 describes the functional capabilities from the user's point of view. Stage 2 defines the functional behaviour in
terms of Functional Entities (FEs) and information flows. Stage 3 gives a precise description of the Supplementary
Service from the implementation point of view. It defines the protocol for the service and the encoding rules for the
information flows. It defines the processes for the functional entities and their behaviour. The described protocols and
behaviour apply to the SwMI, for the MS and for the LS and can be applied over the ISI between TETRA systems.
Aspects relating to all supplementary services are detailed in EN 300 392-9 [2].

3.1 Definitions
For the purposes of the present document, the following terms and definitions apply:
authorized user: user who is authorized to define, activate, deactivate and interrogate the SS-PC
Functional Entity (FE): specifies the functional characteristics of the SS sub-entity within an MS, a LS or a SwMI
related to an SS-PC action, e.g. management or operational functions of SS-PC
home system: TETRA system to which the subscriber identity is permanently defined
management functions: management functions for SS-PC are definition, activation, deactivation and interrogation
priority level: pre-agreed value allocated to each mobile Individual TETRA Subscriber Identity (ITSI) or Group

4 SS-PC stage 3 specification
4.1 General
This clause describes the SS-PC services offered by Supplementary Service (SS) and call control sub-entities of CMCE
of the TETRA voice plus data layer 3 service boundary in the MS/LS. The SS-PC services shall be offered at the
Supplementary Services service access point (TNSS-SAP), the Call Control services Service Access Point
(TNCC-SAP). The SS-PC services described in this clause shall be applicable for the MS and the LS.
NOTE: The SS-PC services within the SwMI are outside the scope of the present document.
The SS-PC services specified in the present document shall complement the Supplementary services and Call control
services specified in EN 300 392-2 [1] clause 12 and 11 respectively and the Supplementary Services general design
standard EN 300 392-9
