    摘要: A method and system of managing call forwarding includes establishing criteria for selecting among possible links between nodes for forwarding calls from an originating node to a destination node. In the preferred embodiment, the selection of the possible links is made at a called node from which the call is to be forwarded. Based upon the administrable criteria, there is a determination as to whether an intermediate node along the call path between the originating node and the called node is to be selected for initiating the forwarding path. If an intermediate node is selected, a request is transmitted to the intermediate node to initiate the forwarding path to the destination node. On the other hand, if no intermediate node is selected, a determination is made as to whether to initiate the forwarding path from the originating node or from the called node. Again, the determination is made according to the administrable criteria. Typically, the most important factor in selecting among the nodes relates to minimizing the link necessary to connect the calling party to the forwarded-to party, thereby releasing links for other use within a network.

    摘要: Routing calls using a new protocol message which is a redirect message in a telecommunication system having a number of switching nodes to avoid circular paths among the switching nodes and for rerouting calls in the event of failures or overload conditions. During the establishment of a call from an originating switching node to a destination switching node where the call path has already been setup from the originating switching node through an intermediate switching node, a switching node is responsive to a setup message from the intermediate switching node requesting extension of the call path through the switching node to determine if such an extension would create a circular path. If circular path would be created, the switching node redirects the call (by using the redirect message) back to the intermediate switching node and indicates in that message to which switching node the call path should be extended. In response to the redirect message, the intermediate switching node reroutes the call path. Further, the redirect message entirely removes the call path between the switching node and intermediate switching node.

    摘要: Procédé servant à acheminer une demande de service dans un réseau (100) comprenant des noeuds (101-104) interconnectés avec des liaisons. Le réseau est aussi conçu de façon que chaque noeud puisse communiquer avec chacun des autres noeuds. A des intervalles de temps présélectionnés, des ensembles d'itinéraires dans le réseau sont générés en réaction à la configuration du réseau et aux informations de trafic. De même, à des intervalles de temps prédéterminés, des facteurs d'occupation sont calculés en fonction de la configuration du réseau et en réaction aux informations de trafic. Les facteurs d'occupation sont proportionnels à des facteurs d'occupation non associés et aux facteurs d'attribution relatifs aux appels des diverses paires de noeuds; chacun de ces derniers facteurs est dérivé d'un plan d'acheminement nominal dans lequel un appel de la paire de noeuds correspondante n'est traité comme perdu que s'il est bloqué sur tous ses itinéraires autorisés. A intervalles prédéterminés, les données d'utilisation du trafic sont mesurées. A intervalles réguliers, les facteurs d'occupation correspondant à l'état occupé-inactif des liaisons sont utilisés pour calculer des valeurs d'occupation (340) relatives à chacun des itinéraires. Les valeurs d'occupation qui ne dépassent par un seuil prédéterminé génèrent des ensembles d'itinéraires séquentiels (350) pour chaque intervalle. Le trafic offert est alors acheminé séquentiellement par les ensembles d'itinéraires séquentiels.

    摘要: For synchronization signals of zeroth and first series, a synchronization signal processing system comprises synchronization trunk device of the zeroth and the first series (77(0), 77(1)) for producing particular signals of the zeroth and the first series, respectively, and being exclusively operable in master and slave states. When used in a switching center of a low hierarchy, each trunk device of a local series, which is one of the zeroth and the first series, is supplied as three input signals with the synchronization signals of the local series and a different series with highest (1) and middle (2) degrees of priority and the particular signal of the different series with a lowest (-3) degree of priority, selects as a normal signal according to the degrees one of the synchronization signals in the master state and one of the three input signals in the slave state that are normal, and generates as the particular signal of the local series a regenerated synchronization signal with its phase adjusted to the normal signal. A relay trunk device of the local series (95(0), 95(1)) is supplied with the particular signals of the local and the different series with higher (1) and lower (2) degrees of priority and selects as a phase synchronized synchronization signal of the local series according to the higher and the lower degrees one of the particular signals that is normal. In a switching center of a highest hierarchy, the three input signals may be a synchronization signal of the local series produced in a lower hierarchy switching center, the phase synchronized synchronization signal of the different series, and the particular signal of the different series.
