  • Method for the optimization of network traffic, and associated implementation device
    Patent number: 7228330
    Abstract: In a method in which a proxy is installed in a mobile telephone, this proxy has the role of simulating a service server to make a client application of the telephone believe that communication has truly been set up with a service server and thus obtain local processing, in the client apparatus, of the maximum number of the requests sent by the client application. Another role of this proxy is to engage in dialog with a network controller server. The network controller server substitutes itself for the client application for the polling and communicates with the proxy for the management of the requests sent by the client application.

  • Method and device for the broadcasting of multimedia contents to mobile terminals
    Publication number: 20040142656
    Abstract: To broadcast a set of multimedia contents to mobile terminals located in a geographical zone, a broadcasting server addresses them through a short broadcast message. A geographical zone is defined as a set of cells of a mobile telephony network. The short message is received by all the mobile terminals present in these cells. The reception of this short message prompts the connection of this terminal to the broadcasting server for the retrieval of a set of multimedia contents associated with the short message. The retrieval is done in either WAP/GPRS mode or voice mode.
