Methods and systems are provided for using a PDSN in a wireless communication network that includes multiple EP addresses and multiple corresponding physical interfaces. Through the use of multiple EP addresses and interfaces, the throughput of the PDSN may be substantially increased. Additionally, the multiple W addresses and interfaces may be used to provide redundancy in order to protect against software or hardware failures. According to the methods and systems of the invention, moreover, the risk of internal hard handoffs resulting from the use of a PDSN having multiple IP addresses and interfaces is eliminated or at least substantially reduced.
La présente invention concerne des procédés et des systèmes pour utiliser dans un réseau de communication hertzienne, un noeud de transmission de données par paquets (PDSN) qui comprend des adresses IP multiples et de multiples interfaces physiques correspondantes. L'utilisation de multiples adresses IP et de multiples interfaces permet d'augmenter sensiblement le débit des PDSN. De plus, les multiples adresses IP et les multiples interfaces peuvent être utilisées pour créer une redondance qui sert de protection contre les erreurs de logiciel ou de matériel. De plus, grâce aux procédés et aux systèmes de l'invention, le risque de transferts internes difficiles résultant de l'utilisation d'un PDSN ayant des adresses IP multiples et des interfaces multiples, est éliminé ou au moins sensiblement réduit.
