Least-cost routing (original) (raw)
In voice telecommunications, least-cost routing (LCR) is the process of selecting the path of outbound communications traffic based on cost. Within a telecoms carrier, an LCR team might periodically (monthly, weekly or even daily) choose between routes from several or even hundreds of carriers for destinations across the world. This function might also be automated by a device or software program known as a least-cost router.

| dbo:abstract | Der engl. Begriff Least Cost Router (LCR) bezeichnet in der Telekommunikation eine Vorrichtung, die eine automatische Auswahl des preiswertesten Telefonanbieters durchführt, wobei im leitungsvermittelten Festnetz üblicherweise Call-by-Call genutzt wird. Der Sinn eines LCR besteht darin, das manuelle Vergleichen von Gebührentabellen zu automatisieren. In Deutschland ist auch der Begriff Tarifmanager als Gattungsbezeichnung für Least Cost Router in Verwendung, jedoch handelt es sich hierbei um den geschützten Markennamen eines führenden LCR-Herstellers. Der LCR kann als Hardwarezusatz für eine Telefonanlage, als kleines, dem analogen Telefon vorgeschaltetes Gerät oder auch als Software ausgeführt sein; Software-basierte Lösungen entfalten ihren vollen Komfortumfang meist in Verbindung mit IP-Telefonie (Voice over IP, VoIP) oder CTI-Systemen, während Hardware-basierte Lösungen – zumindest theoretisch – nach einer einmaligen Konfiguration wartungsfrei arbeiten können.

(en) Le Least-Cost Routing (LCR) ou Routage au moindre coût est un système permettant de sélectionner parmi plusieurs opérateurs télécom, celui proposant la meilleure route, pour chaque appel, en fonction de plusieurs critères tels que le coût de la destination appelée et la qualité. Le système de LCR est utilisé par les opérateurs pour la gestion de leur trafic voix, mais également par certaines entreprises souhaitant optimiser leurs coûts de télécommunications. * Portail des télécommunications (fr) Il Least Cost Routing (abbreviato spesso in LCR), in un sistema telefonico rappresenta una funzione pre-instradamento di una chiamata per la selezione di un operatore piuttosto che un altro. Tale funzione, in base al prefisso nazionale e geografico del numero chiamato, seleziona l'operatore che, secondo specifici criteri di qualità e costo, rappresenta la scelta migliore verso cui instradare la comunicazione. I parametri di scelta dell'operatore da utilizzare derivano da dati statistici sulle chiamate precedentemente inoltrate, come la percentuale di chiamate andate a buon fine (cioè per le quali c'è stata effettivamente una connessione col numero chiamato, e che indica la disponibilità di un operatore), e la media di minuti di conversazione per ogni chiamata (che indica se la connessione verso un operatore è stabile o meno). Tra gli operatori che hanno le migliori statistiche di chiamata, vengono poi selezionati quelli con le tariffe più competitive. Specialmente nei nuovi sistemi di telefonia VoIP tale criterio è spesso utilizzato per garantire costi contenuti e qualità alta nell'instradamento delle chiamate verso la rete telefonica tradizionale.

Least Cost Routing) to usługa central telefonicznych typu PBX polegająca na tym, że centrala potrafi automatycznie skierować ruch wychodzący do sieci wybranego operatora, bramki GSM lub bramki VoIP tak, aby koszt połączenia był najniższy. Użytkownik nie musi wybierać żadnych prefiksów, odbywa się to bez jego wiedzy. Przykładowo jeśli centrala podłączona jest do sieci 2 operatorów, z których jeden oferuje niższe stawki połączeń lokalnych a inny międzystrefowych to centrala potrafi na podstawie wybieranego numeru rozpoznać typ połączenia i wybrać tańszego operatora. Może to być również ten sam operator, u którego wykupiliśmy na dwóch liniach telefonicznych różne taryfy; w tym przypadku wybierana jest niższa taryfa. (pl) Least Cost Routing (сокр. от англ. LCR — «маршрутизация по критерию наименьшей стоимости») — технология (функция), обеспечивающая прохождение телефонного вызова от одного абонента к другому по маршруту, обеспечивающему наименьшую стоимость телефонного соединения (наименьшую стоимость минуты разговора). Оборудование с поддержкой LCR наиболее активно используется в корпоративном секторе. Основное достоинство LCR — возможность заметно сократить расходы компании на исходящий телефонный трафик. Также, LCR наряду с сетевой нумерацией в некоторых случаях позволяет использовать офисную АТС в качестве транзитной. (ru) |
