27、2-05) 1 Scope The present document defines the stage 1 specifications of the Supplementary Service Priority Call (SS-PC) for 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
28、the service description of the supplementary service and the 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 shall be outside
29、the scope of the present document. The SS-PC enables a user to have preferential access to the network resources in the TETRA system. 2 Refe re nces The following documents contain provisions which, through reference in this text, constitute provisions of the present document. References are either
30、specific (identified by date of publication andor edition number or version number) or non-specific. For a specific reference, subsequent revisions do not apply.

38、) stage 1 specification 4.1 Description 4.1.1 General description SS-PC allows the infiastructure to give priority access to network resources to calls which have been sent with priority status in times of congestion. The priority level shall not apply to the initial uplink access but shall apply to
39、 the resources across the infiastructure and to the radio link at the called user. The priority level shall be sent with the initial call set-up message, or the network may select a default level if the user has riot chosen a level, and the level may be indicated to the called user as part of normal
40、 call control information. In a typical scenario there may be eight priority levels, each one in turn giving an enhanced performance in times of network congestion. A call attempt that has been assigned a higher priority than another call attempt shall be given resources by the infrastructure in pre
41、ference to a call attempt with lower priority. The precise queuing procedure shall be an operator option. ETSI 9 ETSI EN 300 392-10-10 V1.2.1 (2002-05) The uses of priority level may be e.g.: - - to determine the priority of queuing for resources in the network; to indicate the importance of the inc
42、oming call to the called user. 4.1.2 Qualifications on applicability to telecommunication services This supplementary service shall be applicable to all TETRA circuit mode teleservices and to all TETRA circuit mode bearer services. 4.2 Procedures 4.2.1 Provision, assignment and withdrawal Provision
43、of SS-PC shall be by pre-arrangement with the service provider. System may withdraw the service temporarily or permanently at any time without further information. SS-PC shall be provided on a per TETRA number (ITSUGTSI) basis. For each ITSUGTSI, the supplementary service may be subscribed to for ev
44、ery basic service subscribed to at that ITSUGTSI or for only some of the basic services subscribed to at that ITSUGTSI. A user shall be provided with a range of priority levels within which he may select on a per call basis. The priority level ranges may be defined upon provision or the system may d
45、ownload priority values at any time for user ITSUGTSI. MS may support those assigned values. 4.2.2 Normal procedures 4.2.2.1 Activation, deactivation, defin ition, registration, interrogation and cancellation 4.2.2. I. 1 Activation and deactivation SS-PC shall be activated by the service provider up
46、on provision and deactivated upon withdrawal. The optional assignment may be used to activate and deactivate the priority levels upon assignment. The deactivation may force pre-defied priority values as set upon provision. 4.2.2.1.2 Remote activation and deactivation Void. 4.2.2.1.3 Definition As an
47、 implementation option, authorizedregistered users may dynamically define the priority level or priority level range for each registered ITSUGTSI. This process supplements the provision process, where the ITSIs shall be allocated a priority level range upon provision, and facilitates the “on line“ c
48、hange of priority level ranges. The defiied values are downloaded to the user MSs using assignment. 4.2.2.1.4 Registration As an implementation option authorized users, capable of defining andor remotely activating or deactivating the priority level or priority level range, shall be registered with
49、the applicable ITSUGTSI range. The registration is a part of provisioning. ETSI 10 ETSI EN 300 392-10-10 V1.2.1 (2002-05) 4.2.2.1.5 Interrogation The infrastructure may provide interrogation, which can be local, remote or both. If interrogation is provided, an SwMI shall support interrogation on a per number basis, e.g.: - activatedde-activated; - priority levels per service; - result of the interrogation; - assignment status; and - whether acknowledgement of the assignment is requested from the user. 4.2.2.1.6 Cancel lati on Shall not be applicable. 4.2.2.2 Invocation and ope
