24、-1 1-14 VI .I .I (2002-07) 1 Scope The present document defines the stage 2 specifications of the Supplementary Service Late Entry (SS-LE) for the Trans-European Trunked Radio (TETRA). The SS-LE allows radio users to be informed of and, if they are concerned, to join an already existing point-to- mu
25、ltipoint speech or data call. Man-Machine Interface (MMI) and charging principles are outside the scope of the present document. Stage 2 describes the functional capabilities of the supplementary service introduced in stage 1 description. Stage 2 identifies the functional capabilities for the manage
26、ment of the service in the Switching and Management Infrastructure (SwMI), in the Mobile Station (MS) and in the Line Station (LS). Stage 2 also describes the information flows between these entities and also the flows sent over the Inter-System Interface (ISI). NOTE: The stage 2 description is foll
27、owed by the stage 3 description, which specifies the encoding rules for the information flows and process behaviour for the different entities in SwMI, MS and LS of the service. Aspects relating to all supplementary services are detailed in EN 300 392-9 4. 2 Re fe re nces The following documents con
28、tain provisions which, through reference in this text, constitute provisions of the present document. References are either specific (identified by date of publication andor edition number or version number) or non-specific. For a specific reference, subsequent revisions do not apply. For a non-spec
29、ific reference, the latest version applies. il ETSI ETS 300 392-1 1-16: “Terrestrial Trunked Radio (TETRA); Voice plus Data (V+D); Part 11 : Supplementary services stage 2; Sub-part 16: Pre-emptive Priority Call (PPC)“.

32、 (2002-07) 3 3.1 Definitions and abbreviations De fi nit ions For the purposes of the present document, the following terms and definitions apply: authorized user: identified user who is able to define and interrogate the SS-LE parameters forced LE: User is forced to join to the indicated call. NOTE
33、: The user should join the ongoing multipoint call as soon as he receives a late entry indication. If the user is already engaged in another communication, the user has to join the highest priority call. LE acknowledgement: indication sent in LE messages by a SwMI to inform a member who would like t
34、o join the call that he has to inform the SwMI of his entering the call LE broadcast: indication sent by a SwMI to inform members of a multipoint call which are currently not already involved in this call that they can join directly an existing communication (a channel is already allocated in this c
35、ell) LE paging: indication sent by a SwMI to inform members of a multipoint call which are currently not already involved in this call that they need to ask for a communication channel for that call if they wish to participate the call (a channel is not yet allocated in this cell) user A: calling pa
36、rty in a call user B: party that receives the SS-LE indications about an ongoing call server user: party that receives the SS-LE indications about an ongoing call and joins the call NOTE: Also known as user B. 3.2 Abbreviations For the purposes of the present document, the following abbreviations ap

In case of LE acknowledgement, FE1 shall send the acknowledgement when it participates in an ongoing call. In case of LE paging, FE1 shall send the paging response when it aims to participate in an ong
42、oing call. If FE1 is in visited SwMI FE1 shall send the messages to FE2 in visited SwMI. 4.2.2 SS-LE functional entity, FE2 At the reception of call invocation request from a calling user A, FE2 shall determine if the SS-LE is invoked. If so, FE1 shall determine the applied SS-LE type and shall star
43、t operation of the SS-LE. During operation FE2 shall send the notifications of SS-LE to FEls. FE2 shall receive SS-LE definition requests from FE3s. FE2 shall analyse the requests and if they are found authorized and correct, FE2 shall make the defiiitions to the system and shall acknowledge to FE3.
44、 If not, FE2 shall reject the request and send a negative acknowledgement to FE3. FE2 shall also receive SS-LE interrogation requests from FE3 about availability or state of a SS-LE service. FE2 shall fetch the response for the interrogation and if FE2 finds the request authorized it shall send the
45、response to FE3. If the basic service to which SS-LE is defiied, extends to another TETRA system (visited SwMI), FE2 shall send a SS-LE information flow to visited SwMI FE2 to indicate if SS-LE should or should not be invoked in visited SwMI.
