16、 The present GTS covers the means by which mobile users, and callers to a GSM network, will be given information regarding progress of their calls. Indications of call progress, such as ringing, engaged, unobtainable, and no radio channel, may in principle be verbal message, tones, displayed text or
17、 graphical symbols. Which combination of these applies may depend on the message, the MS and selection by the user or PLMN operator. However, verbal announcements will generally be reserved for situations which are peculiar to a mobile network, where users may be unfamiliar with any tone chosen to i
18、ndicate conditions such as “call diversion“ or “subscriber not available“. It may also be desirable to add comfort indications (e.g. tones, noise, music, clicks) while a call is being connected, since silence may cause an unfamiliar user to believe that nothing is happening. Generally, on data calls
19、, and on the data part of alternate speech/data or speech-followed-by-data calls, PLMN generated network tones and announcements should be muted.
