<p>The present invention relates to handling of time zones in a telecommunication system with personal mobility and time-dependent routing, particularly in a telecommunication system such as UPT (Universal Personal Telecommunication). The system is, according to the invention, arranged to calculate the time difference between a time zone (TZB), which is obtained from a subscriber (B), particularly a time zone (TZ4) where a subscriber (B) permanently or temporarily is located, and a time zone (TZ0) where the routing takes place, particularly where a node (N) is located and to caculate the subscriber's current time by adding the time difference to the current time where the routing takes place. The time-dependent routing may comprise at least one time table (TTB) for at least one subscriber (B), which time table (TTB) includes at least two time periods (TP) and where for each time period (TP) at least one terminal (T) of function (F) is defined to which the subscriber (B) incoming traffic is intended to be routed. Corrections for daylight saving rules may be included. Menues for handling failed call setups and menues for callback are comprised in the invention.</p> |
