ETRs are informative documents resulting from ETSI studies which are not appropriate for European Telecommunication Standard (ETS) or Interim European Telecommunication Standard (LETS) status. An ETR may be used to publish material which is either of an informative nature, relating to the use

10、or application of ETSs or I-ETSs, or which is immature and not yet suitable for formal adoption as an ETS or LETS.

11、defines the TETRA Man-Machine Interface (MMI) for the TETRA Mobile Station (MS) which can be a hand portable or mobile (vehicular mounted) station. The objective of this ETR is to describe the minimum MMI to gain access to, and control of, the TETRA bearer service and teleservice, and TETRA suppleme

12、ntary services, defined in ETS 300 392-2 l and ETS 300 396-3 2. Additionally it is the purpose of this ETR to aim for a common set of interfaces and interactions that will describe the essential parts of the MMI such that a certain degree of harmonized behaviour amongst the TETRA manufactures can be

13、 obtained. It is however not the purpose to mandate a specific implementation of an interface or interaction procedures but rather to establish the common behaviour exposed at the MMI interface and by the MMI interaction procedures. In general this ETR follows the rules and recommendations laid down

14、 by the ETSI Technical Committee for Human Factors (TC-HF) in their specifications referred to in the reference list (see clause 2). 2 References For the purposes of this ETR, the following references apply: i31 ETS 300 392-2: “Radio Equipment and Systems (RES); Trans-European Trunked Radio (TETRA);

It is envisaged that a Mobile Station (MS) can be one of the access points from where a user c

30、an interact with the TETRA system. Therefore a MS should provide the necessary keys, buttons, visual and audible indication that support human service interaction. The following physical interfaces can be provided by a MS: - keypad for entering alphanumeric numbers signs or codes: - PTT key for cont

31、rolling the speech path; - emergency key for invoking a service with emergency priority: - on/off key for turning the MS on or off; - volume key(s) to lower or increase the volume in handsets, loudspeakers etc.: - visual indications to the user presented in form of icons, or LEDs, or in a display fo

32、r indications of responses to service invocations, or for indications of service requests to be served: - audible indications to the user presented in loudspeakers or hand sets for indications of responses to service invocations or for indications of service requests to be served. Other invocation k

33、eys or indications may exist to support other services and functions of the TETRA system. Also other functions and services than those described in this ETR can be supported by the keys, buttons, visible and audible indications described in this ETR. If the latter is the case every care should be ta

34、ken to maintain the original operational aspects of the keys, buttons, visible and audible indications so that a user is not confused or misled by the operation of the additional services. In the following each of the physical interfaces as outlined above is described further. It is important to not

35、ice that a so called “physical interface“ which supports invocation of a particular service does not necessarily have to be implemented in a certain way, e.g. an emergency key can be implemented as a separate key, as an entry in a displayed menu or as a voice activation. 4.2 Keypad As an option a MS

36、 can be equipped with a keypad. When a keypad is provided the layout should be implemented either as a standard keypad or as an enhanced keypad. 4.2.1 Standard keypad The following keypad in figure 1 is a 4 x 3 array for the numeric keys 09 and symbols “star“ (*) and “square“ (#). The keypad follows

37、 the standard telephone keypad array as specified in ETS 300 640 3. Figure 1 : Standard keypad for a TETRA MS ETSI ETR*zq4 96 3400855 OL2843b b5L = Page 10 ETR 294: August 1996 The keys 09, and # corresponds to the same digits 09, and # in the Circuit Mode Control Entity (CMCE) Dual Tone Multiple Fr

38、equency (DTMF) field of the TETRA V+D Air Interface standard (see ETS 300 392-2 l). 4.2.2 Enhanced keypad The keypad may be expanded to a 4 x 4 array covering enhanced radio or telecommunication functionality if applicable. The enhanced keys are “A“, “B“, “C“ and “D“ and the coupling with the standa

39、rd keypad is shown in figure 2. Figure 2: Expanded keypad for a TETRA MS The enhanced keys in the expanded keypad shown in figure 2 corresponds to the same digits “A“, “B“, “C“ and ID“ in the CMCE DTMF field of the TETRA V+D Air Interface protocol (see ETS 300 392-2 l). NOTE: The “Register Recall“ k

40、ey often used in connection with supplementary services can be one of enhanced keys, e.g. key “B“. 4.3 Other keys There may be other keys used at the air interface, however there should be no requirement to implement the keys described below and therefore the subclauses are provided for information

41、only. 4.3.1 Push-To-Talk (PlT) key The PTT key plays a significant role in the request-grant transmission process which is part of the basic operation in a TETRA V+D simplex or semi-duplex system. When PTT key is used it should at a minimum operate as follows: - when the PlT is pushed it means that

42、the speech direction is from the infrastructure (SwMI); when the PTT is released it means that the speech direction is to the MS, voice. - MS to the TETRA .e. the MS receives There can exist additional functionality connected to the PlT key, e.g. control of data messages, but that should not affect

43、the normal operation of the PTT. NOTE: The implementation of the PTT key is not restricted to a physical push button. It is envisaged that other implementations, e.g. VOX (Voice Operated Switch), is a possibility as long as the PTT functionality for the user is the same. ETSI ETRr294 96 3400855 0328

44、437 598 111 Page 11 ETR 294: August 1996 4.3.2 Emergency key usage An emergency key can exist as a separate key, as menu driven function or as a separate accessory outside the MS. Whatever the implementation is, the invocation of an emergency situation using the emergency key should lead to mapping

45、of the emergency priority onto the TETRA Air Interface signalling. For example one or more of the following cases are possible: - - activating the emergency key invokes Short Data Service (SDS) precoded emergency message; activating the emergency key invokes a TETRA teleservice, e.g. a group call or

46、 individual call, with emergency priority connected to the service request; - activating the emergency key invokes a TETRA bearer service, e.g. a data call, with emergency priority connected to the service request. 4.3.3 Onioff key usage An on/off key may be present in a MS. The on/off key can be im

47、plemented e.g. as an integrated part of a vehicular installation, as a separate key or keys or as soft-keys. Whatever the implementation is the behaviour of the on/off key should be as follows: - when a MS is in a power off state, the activation of the on/off key should power the MS up. At power up

48、the MS may apply for service from the TETRA infrastructure (SwMI) according to the TETRA V+D standard (see ETS 300 392-2 l); - when a MS is in a power on state, the activation of the onoff key should force the MS to power off while at the same time detach its services from the TETRA infrastructure (

49、SwMI). NOTE: Applying for service at power up is not necessarily bound to the on/off key. There could exist other functionality in connection with the activation of the on/off key, e.g. choosing network, choosing mode such as trunk mode or direct mode. 4.3.4 Volume key usage The volume key or volume keys may be present in an implementation as e.g. a rotary switch, an up/down key or as part of a menu driven functionality. Whatever the implementation is it should be unambiguous to the user how the operation works, e.g. if the volume is indicated by numbers either on the displ
