US Patent 8244887 HTTP push to simulate server-initiated sessions

A mobile device apparatus uses an HyperText Transfer protocol (HTTP) push operation to simulate server-initiated sessions. The illustrative mobile device apparatus comprises a push server logic operable in a push server that sends a message to a mobile device over a network. The push server logic is configured to receive a GET command from a mobile device. The GET command includes a mobile device identifier parameter and a timeout parameter designating a maximum time interval for the push server to reply with a message. The push server logic holds a GET command session until expiration of a timeout designated by the timeout parameter in a condition that no message is targeted to the mobile device. The push server logic terminates the GET command session by sending a message immediately in a condition that the message is targeted to the mobile device.
