Provided are a device and method for maintaining a communication session during a network transition. In one example, the method includes monitoring, by a client, a connection with a first network to determine whether a signal strength of the connection falls below a threshold value. The client establishes a connection with a second network if the signal strength of the connection with the first network falls below the threshold value. Establishing the connection with the second network includes obtaining an address and port assignment corresponding to the client from the second network. The client uses the obtained address and port assignment to maintain a communication session during the changeover from the first network to the second network.

La présente invention concerne un dispositif et un procédé permettant de conserver une session de communication pendant une transition de réseau. Dans un exemple, le procédé comprend la surveillance par un client d'une connexion avec un premier réseau pour déterminer si le niveau de signal de la connexion tombe en dessous d'une valeur de seuil. Le client établit une connexion avec un second réseau si le niveau de signal de la connexion avec le premier réseau tombe en dessous de la valeur de seuil. L'établissement de la connexion avec le second réseau comprend l'obtention d'une attribution d'adresse et de port correspondant au client du second réseau. Le client utilise l'attribution d'adresse et de port obtenue pour conserver une session de communication pendant le passage du premier réseau au second réseau.
