Patent

CA 2139111

A fallback strategy for a system (700) and method (200) is provided for rerouting a call that fails to be established utilizing a first set of constraints in a communication network system. This strategy enables the communication network system to utilize a look-around-first type of preemption that avoids unnecessary preemption and provides alternate routing for a call according to predetermined constraints selected by a user.

L'invention est une stratégie de secours pour un système (700) et une méthode (200) de communication qui consiste à utiliser un premier ensemble de contraintes dans un réseau de communication afin de réacheminer un appel pour lequel la communication n'a pu être établie. Cette stratégie permet au réseau de communication d'utiliser des réquisitions après survol qui évitent les réquisitions inutiles, et de réacheminer un appel d'après des contraintes préétablies par l'utilisateur.
