METHOD AND APPARATUS FOR REDUCTION OF CALL SETUP TIME USING ANTICIPATION TECHNIQUE FOR MULTIMEDIA APPLICATIONS IN WIDELY DISTRIBUTED NETWORKS

摘要

In a widely distributed digital communication network call delays andeventual outcome are anticipated (i.e., expected call outcome) at the initiationof a call at an originating terminal and the call is completed by signal switchingto its destination terminal and by decreasing the number of related messagetransfers between network controllers and hubs required to complete thebalance of administrative refinements of the call connection. The routing stepsfor setting up the call trajectory to the destination hub are completedimmediately before the administrative steps, such as authentication, accesscontrol, bandwidth availability etc., are performed. Administrative refinementssubsequent to the preliminary call set up are performed in a distributivemanner. Administrative and capacity items are determined and completed postroute determination and computed or accessed in parallel making thisinformation available for a final call set up. If this information is adverse thecall is immediately terminated. In one aspect the processors for administrativeand capacity determination are connected in a parallel manner and workconcurrently.
