ETRs are informative documents result
10、ing from ETSI studies which are not appropriate for European Telecommunication Standard (ETS) or Interim European Telecommunication Standard (I-ETS) status. An ETR may be used to publish material which is either of an informative nature, relating to the use or application of ETSs or I-ETSs, or which
11、 is immature and not yet suitable for formal adoption as an ETS or I-ETS.

12、accessing TETRA systems and external systems including e.g. Private Automatic Branch Exchange (PABX) and ITU-T Recommendation E.164 lo domain, mapping of wer visible numbers to TETRA addresses exchanged over the air interface, and further defines TETRA Short Subscriber Identity (SSI) addresses to be
13、 used to access these external systems. The Man Machine Interface (MMI) issues have been addressed in this ETR only to the extent of those strictly related to numbering and dialling. This ETR is applicable to TETRA terminal equipment with a basic or enhanced number keypad, as in ETR 294 12, or with
14、a display capable of displaying numbers in decimal format, as well as all the TETRA terminal equipment employing air interface address exchange. Allocation of predefined SSI addresses in this ETR is also applicable to TETRA Switching and Management Infrastructure (SwMI) applications. 2 References Fo

Additi
24、onally, the terms defined in ETS 300 392-2 2, and ETS 300 396-3 5 apply. 3.2 Abbreviations For the purposes of this ETR, the abbreviations in ETS 300 392-2 2 and ETS 300 396-3 5 apply. 4 General The user input in case of establishing a call is defined for the purposes of this ETR as three sequential
25、 events: 1) algorithm selection; 2) user dialled digits; and 3) connect event. Algorithm selection is the selection of dialling algorithm to be applied to the user dialled digits. Connect is the event, which terminates the user input related to the digits and normally causes a call set up. Methods f
26、or algofihm selection are defined in clause 6. Dialling algorithms defined in clause 7 specify how the user dialled digits are interpreted and how they are transferred over the TETRA V+D air interface. The connect event itself can be e.g. a user press of a specific connect button or Push-To-Talk (PT
27、T) button, and as such is outside the scope of this document. However, the connect event is required in the implementation to comply with this recommendation. NOTE: This definition of the user input for call establishment is valid only for the cases when user dials a number using the number keypad o
28、r selects a number e.g. from a list of predefined numbers. There may be methods to combine all the three events so that e.g. PTT causes a call establishment using a predefined dialling algorithm to a predefined address requiring no explicit dialling event. This ETR does not imply any specific alloca
29、tion scheme of TETRA SSI subscriber addresses within a TETRA network, .e. TETRA SSls may be allocated to any functional purpose independently, or in relationship to user numbering in accordance to this ETR. However, some predefined SSI addresses for STD-ETSI ETR 300-5-ENGL 1998 3900855 0335222 433 P
30、age 9 ETR 300-5: July 1998 accessing external telecommunication systems are specified in clause 12 for the purposes of interworking. It is possible to implement barring of outgoing calls functionality especially based on attempted communication type for each dialling algorithm defined in this ETR. F
31、or example, point-to-multipoint calls would not be allowed using E.164 domain“ dialling algorithm. However, such constraints are outside the scope of this ETR. 5 Numbering within one TETRA network If a TETRA terminal equipment is intended to be used only within a network with no external connections
32、, then there is no need to implement algorithm selection, neither multiple dialling algorithms in that terminal equipment. All the calls from that terminal could be established e.g. using the “Home TETRA network dialling algorithm, as defined in subclause 7.1. 6 Enhanced numbering Networks external
33、to single TETRA network set requirements to numbering used in terminals due to differences of user presentation of numbers in different networks and transfer mechanism of addresses between the networks. If the network, a TETRA terminal is to be connected to, has one or more connections to other exte
34、rnal networks, then the terminal equipment should implement all the appropriate dialling algorithms as required. When more than one dialling algorithms are implemented, then the dialling algorithm selection is required. 6.1 Selection of dialling algorithm As not to restrict progress in MMI innovatio
35、n, it is envisaged that dialling selection may be initiated in many ways. Some current MMI examples are: direct number entry via a keypad, mode selection buttons, and soft key menu selection. This dialling algorithm selection may vary according to the terminal type. One dialling algorithm selection
36、is defined in this ETR, called leading digit method. This method is the recommended one to achieve similar functionally in different implementations. The leading digit method is defined under subclause 6.2. 6.2 Leading digit dialling algorithm selection The dialling algorithm used may be selected by
37、 the first digit in any number input dialled by the user, or selected by user e.g. from a radio short code memory. The sequence of the full number input, as defined in the algorithms in clause 7, is amended by the leading digit, and it becomes part of the user visible numbers, .e. there is no separa
38、tor between the leading digit and actual number. It should be ensured in the terminal implementation, that no non-deterministic user input will result in an ambiguous call Set-up attempt over the air interface. For example, if user inputs a leading digit that is not assigned to any of the dialling a
39、lgorithms, then the terminal should not try to establish the call and appropriate feedback should be given to the user. 6.2.1 Recommended values for first digits Leading digit value zero is recommended to be used to select E.164 domain algorithm, see subclause 7.9. However, it is not mandatory to us
40、e leading digit value O for that purpose. 6.2.2 Leading digit forwarding It is an option in the leading digit method to choose whether the first digit is also transferred over the air interface as part of the subscriber number. This option could be set, or not, for each leading digit value independe
41、ntly. STDoETSI ETR 300-5-ENGL 3998 3400855 0335223 37T 9 Page 10 6.2.3 ETR 300-5: July 1998 Mapping of first digit values to dialling algorithms There may be one to one relationship between each first digit and dialling algorithm, or each of the first digits may cause the same algorithm to be applie
42、d depending on the terminal equipment implementation. It is also possible to combine the leading digit method for the dialling algorithm selection with other possible methods so that some of the algorithms are to be selected based on the first digits, while the rest by some other MMI functions. 7 Di
43、alling algorithms A terminal equipment implementing a dialling algorithm may apply it several times for different purposes, e.g. PABX gateway algorithm may be applied several times to access different PABX gateways. In that case the selection of dialling algorithm should differentiate between the va
44、rious instances of that algorithm, see subclause 6.1. The Individual TETRA Subscriber Identity (ITSI), Short Subscriber Identity (SSI), Mobile Network Identity (MNI), Mobile Country Code (MCC), and Mobile Network Code (MNC) are defined in ETS 300 392-1 l, clause 7. NOTE: For comparison of TETRA iden
45、tities and address types in other systems, see ETS 300 392-1 l, subclause 7.8.4. If the user dialled digits can not be converted to valid MCC, MNC, or SSI, as defined in algorithms under this clause, then the terminal equipment should not attempt the call set up, but reject the user input and indica
46、te an error in the dial string to the user. NOTE: Checking the erroneous dial string by terminal is assumed only to the extent of the conversion of the dial string, e.g. if user has dialled a subscriber number of 2 digits when it should be eng. 7 digits long. The network is responsible for rejecting
47、 the call set up, e.g. if a call is attempted using an unallocated SSI. Air interface Protocol Data Unit (PDU) elements called party SSI, called party extension, and external subscriber number, are defined in ETS 300 392-1 2, clause 14. Two stage signalling, as described in ETS 300 392-2 2, subclaus
48、es 14.5.1.2.5 and 14.5.1.2.6, is outside the scope of this ETR. Most of the dialling algorithms defined in this clause contain overview illustrations. The symbols used in those figures should be interpreted according to the following key: - D =digit; - B = bit; and - E =element. The number in subscr
49、ipt after the symbol indicates the sequential order of the item, e.g. D dialled by the user, and B is the most significant bit. is the last digit Dashed line in the figures indicates conditional or optional presence of the item surrounded by the line. NOTE: Leading digit method is not part of the definitions of the dialling algorithms in this clause. 7.1 Home TETRA network This dialling algorithm applies to calls to the network the calling party terminal equipment is subscribed to. The length of the user dialled digits may
