Patent number: 9883548Abstract: Systems and methods for maintaining an IP (Internet protocol) connection in a mobile network are disclosed. Techniques are disclosed wherein an optimal keep-alive interval is determined, and dynamic adjustments of keep-alive message interval are employed to prevent detection and counter measure. Keep-Alive schedule information may be determined at a first mobile terminal for a network, and subsequently used for a second mobile terminal when the second mobile terminal encounters that same network. In some embodiments, the Keep-Alive schedule information is stored at a network-node device. In some embodiments, the first mobile terminal and the second mobile terminal are cellular phones.Type: GrantFiled: September 30, 2016Date of Patent: January 30, 2018Assignee: Seven Networks, LLCInventors: Ari Backholm, Mikko Tervahauta, Seppo Salorinne, Jukka Ahonen, Mikko Daavittila, Andrew Everitt, Lauri Vuornos
