23、300 392-1 1-12 VI .I .2 (2003-05) 1 Scope The present document specifies the stage 2 description of the Supplementary Service Call Hold (SS-HOLD) for the Terrestrial Trunked Radio (TETRA). SS-HOLD enables a user to interrupt communication on an existing call and then subsequently, if desired, re-est
24、ablish communication. Man-Machine Interface (MMI) and charging principles are outside of the scope of the present document. Supplementary service specifications are produced in three stages according to the method defined in ITU-T Recommendation 1.130 i. The stage 2 description identifies the functi
25、onal capabilities and the information flows needed to support the supplementary service as specified in its stage 1 description (see EN 300 392-10-12 7). The stage 2 description is followed by the stage 3 description, which specifies the protocols at the air interface and at the various Inter-System
26、 Interfaces (ISI) to support the service. The present document is applicable to TETRA Voice plus Data terminal equipment and networks. 2 Re fe re nces The following documents contain provisions which, through reference in this text, constitute provisions of the present document.

38、ion The functional model shall comprise the following Functional Entities (FES): FE 1 FE2 1 FE2 1 FE25 Affected user SwMI FE FE5 Affected user FE Served user functional entity Served user SwMI FE Served user new SwMI FE ETSI 8 ETSI EN 300 392-1 1-12 VI .I .2 (2003-05) The following relationships sha

41、ocation change of the served user NOTE: Both figures 1 and 2 apply only in the case of individual call since SS-HOLD does not apply to group call. 4.2 Description of functional entities 4.2.1 Served user functional entity, FEI FE1 is the functional entity that serves the calling user for the invocat
42、ion of SS-HOLD. If the served user changes location with one or more individual call still on hold, FE1 may be informed by FE21 about possible changes for those calls. It will process that information according to its contents; notably if it indicates a call reference change for some calls on hold,
43、it will update accordingly its call references for those calls. FE1 may also relay the interrogation requests received from the served user to FE21, and the corresponding responses from FE21 to the served user (as indication primitives). ETSI 9 ETSI EN 300 392-1 1-12 VI .I .2 (2003-05) 4.2.2 Served
44、user SwMI functional entity, FE21 When it receives a SS-HOLD invocation from FE1, FE21 checks whether SS-HOLD has been activated (i.e. subscribed) and, if so, puts the call on hold, in informing FE5 and FE25. If the served user changes location with an individual call still on hold, FE21 may attempt
45、 to create FE21. If that attempt is successful, FE21 passes the data about that call to FE21. If not, it informs the collocated individual call control entity about the situation. 4.2.3 Served user new SwMI functional entity, FE21 If the served user changes location with a call still on hold, FE21 m
46、ay be created. FE21 then receives the data about that call, informs FE1 about the calls on hold for which one of the two following changes has occurred due to the location change: call reference changed or call lost. After that FE21 replaces FE21. 4.2.4 Affected user SwMI functional entity, FE25 FE2
47、5 receives from FE21 the information that SS-HOLD has been invoked (by the served user) for the call and passes it to the collocated individual call control entity. 4.2.5 Affected user functional entity, FE5 FE5 is the functional entity that serves the affected user to inform him when the call has b
48、een put on hold and then, when it is retrieved. 4.3 Relationship of functional model to basic call functional model Although no formal models have been defined for basic individual call or for basic group call, those models can be readily derived from the PISN model for basic call, in ISO/IEC 11574
49、9. FE1 shall be collocated with the CCA of the calling user or of the called user in an individual call. FE21 shall be collocated with the CC functional entity in the served user SwMI in an individual call. Depending on whether the served user has roamed or migrated (with one or more individual calls on hold), FE21 shall be collocated with the CC functional entity either: in the same served user SwMI if the served user has roamed; in the served user new SwMI if the served user has migrated. FE5 shall be collocated with the CCA of the remote party in an in
