Connection Hold Optimization based on Network Charging Interval

      Disclosed is a method to optimize the savings at a Data
Terminal Device that utilizes Short Hold Mode (SHM) by not clearing a
switched connection prior to the end of a minimum charging interval.

      Transmission and reception of data between systems, using
telecommunications protocols, may utilize a variety of switched and
non-switched connections.  Typically, switched network services are
provided by public networks which provide telecommunications services
(e.g. long distance telephone service) for a fee.

      The fees associated with switched links are usually composed of
an Access Charge, which allows a network user (e.g. Data Terminal
Equipment) to attach to the network using a particular network
interface (e.g. ISDN), and a Use Charge, which allows a network to
access particular services (e.g. long distance services) and which
are usually tariffed on a "use" basis (e.g. length of time the
connection is maintained).

      This invention deals with the use charge for switched
connections that are based on the length of time the switched
connection is connected.  These charges are computed based on the
number of minimum charge intervals that span the call.  Users are
charged for the whole interval if any part of that interval is used.
In most cases, the initial interval is the longest and is sometimes
referred to as the initial minimum charge for placing a call, with
subsequent intervals being shorter.
