Abstract
The present invention provides the benefits of negotiated network resources to session-unaware applications. When a session-unaware application runs on a mobile device, the device, knowing that the application is session-unaware, negotiates appropriate network-policy parameters for the application. The application remains unaware, but it receives the benefits of the network-policy parameter negotiation. The network-policy parameter negotiation is carried on between the mobile device and a “network policy mediator” in the network. Together, they reserve the appropriate network resources and secure the appropriate guarantees. In some embodiments, a software “shim” runs in the network-protocol stack on the mobile device. By intercepting network-access attempts sent by the session-unaware application, the shim knows to begin the network-policy parameter negotiation. In some embodiments, the mobile device downloads information about session-unaware applications from the network. This information includes a list of which network-policy parameter guarantees would be most beneficial to each application.
