Abstract
A telecommunications system and method is disclosed for providing a more accurate measurement of the cumulative path delay present in a call to enable switches to make an informed decision as to the routing method to use. In one embodiment, the Integrated Services Digital Network User Part (ISUP) satellite hop counter field is expanded to include three fields, one for each type of delay: geostationary satellite hops, mid-earth orbit satellite hops and low-earth orbit satellite hops. In an alternative embodiment, a cumulative delay value in milliseconds or centiseconds, instead of the number of satellite hops, can be included in the expanded ISUP satellite hop counter field.
