  • Patent number: 9019965
    Abstract: A data packet routing system is provided wherein: at least one terminal belonging to a private IPv4 network is connected to a gateway itself connected to an IPv6 network; at least one interface device at the interface between said IPv6 network and a public IPv4 network implements a translation function comprising exchanging a private IPv4 address with a public IPv4 address. The gateway allocates to the terminal an IPv6 address by providing an IPv6 prefix with the private IPv4 address of the terminal in its private IPv4 network; said gateway verifying whether IPv4 address conflict exists, and if IPv4 it does exist, for replacing said private IPv4 address locally with a substitute private IPv4 address. A method is provided that routes an IPv4 data packet sent by a source terminal belonging to a first IPv4 domain via an IPv6 domain to a destination terminal belonging to a second IPv4 domain.

  • Patent number: 7567798
    Abstract: The system enables a user of mobile terminal (T1) to store and access to numerous multimedia files with no limit on size relative to the capacities of his mobile terminal. A sorting centre or a web server (CTM, SW) detects a multimedia file (FM) in a message (MT2) transmitted by a second terminal (T2) in order to extract therefrom an address (AT1) of the mobile terminal, a text block (BT) and a detected multimedia file (FM). A storing space (SSM) stores the extracted multimedia file in corresponding relationship with the extracted address (AT1). The sorting centre or a web server establishes a notification command (CN) including the address (AT1) and the text block (BT). A notification server (SN) transmits a storage notification (NSFM) including the text file (BT) to the terminal (T1).
