SS-P
37、PC 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 pri
38、ority calls and the capability to pre-empt users from ongoing calls in order to move them to a 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 Infrastruct
39、ure (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 fl
40、ows may be delivered over the Inter System Interface (ISI). SS-PPC 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. Supplementary Service stage 3
41、 specification is preceded by the stage 1 and the stage 2 specifications of the service. Stage 1 describes the functional capabilities from the users point of view. Stage 2 defines the functional behaviour in terms of Functional Entities (FEs) and information flows. Stage 3 gives a precise descripti
42、on 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 FEs and their behaviour. The described protocols and behaviour apply to the SwMI, for the MS and may be ap
43、plied over the ISI between TETRA systems. Aspects relating to all supplementary services are detailed in EN 300 392-9 3. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document.
