30、 Priority Call (SS-PPC) for the Terrestrial Trunked Radio system (TETRA). Stage 1 is an overall service description from the users point of view but does not deal with the details of the human interface itself. The present document specifies the service description of the supplementary service and t
31、he procedures to be expected with successful and unsuccessful outcomes. In addition the present document specifies the interactions with other TETRA supplementary services and interworking considerations. Charging principles are outside the scope of the present document. The SS-PPC enables a user to
32、 have preferential access to SwMI resources including pre-emption of calls. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document.

Normally the calling user defines the pre-emptive priority level for the call, but SwMI may modify that value or allocate that value. The reasons for modification or allocation are outside the scope of the present document. If the required resources are unavailable (i.e. occupied by other users) for the SS-PPC call SwMI should release resources of the oldest calls with the lowest SwMI
