A method for IP [=Internet Protocol] communication between a mobile terminal and its correspondent node in a mobile radio network. The method comprises establishing an IP connection between the mobile terminal and its correspondent node. After detecting a period of inactivity in the IP connection, keep-alive messages are sent via the IP connection at predetermined intervals, which are varied. The method comprises monitoring the lengths of several periods of inactivity at which the mobile radio network disconnects the IP connection.

Dynamic adjustment of keep-alive messages for efficient battery usage in a mobile network

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.

A method for managing applications configured for execution on a mobile device is provided. The method includes receiving one or more network access requests from one or more applications executing on the mobile device, determining that the mobile device is operating in a background mode, suppressing transmission to a network of the one or more network access requests based on the determination, and transmitting a subset of the one or more network access requests upon transition out of the background mode.

Mobile device having improved polling characteristics for background applications

A method for IP [=Internet Protocol] communication between a mobile terminal and its correspondent node in a mobile radio network. The method comprises establishing an IP connection between the mobile terminal and its correspondent node. After detecting a period of inactivity in the IP connection, keep-alive messages are sent via the IP connection at predetermined intervals, which are varied. The method comprises monitoring the lengths of several periods of inactivity at which the mobile radio network disconnects the IP connection. Based on the monitored lengths of periods of inactivity, a maximum interval (T) between keep-alive messages is determined such that the maximum interval meets a predetermined criterion of statistical confidence, and the interval between keep-alive messages is set to the maximum interval (T).

Systems and methods for aligning data transfer to optimize connections established for transmission over a wireless network are disclosed. In one aspect, embodiments of the present disclosure include a method, which may be implemented on a system, for aligning data transfer to a mobile device to optimize connections made by the mobile device in a cellular network. The method includes batching data received in multiple transactions directed to a mobile device for transmission to the mobile device over the cellular network such that a wireless connection need not be established with the mobile device every time each of the multiple transactions occurs. For example, the data received in the multiple transactions for the mobile device can be sent to the mobile device, in a single transaction over a single instantiation of wireless network connectivity at the mobile device.

Mobile network background traffic data management

Systems and methods for management of a network connection without heartbeat messages are disclosed. One embodiment of a distributed proxy system performs a method for the communication of state between a client and a server in a distributed content delivery network using a state map. The state map sets a predicted communication correspondence frequency and thus eliminates the use or need of heart beat messages to manage session state and/or convey health status of system components.

Method and system for management of a virtual network connection without heartbeat messages

Systems and methods for timing of a keep-alive messages used in a system for mobile network resource conservation and optimization are disclosed. In one aspect, embodiments of the present disclosure include a method, which may be implemented on a system, of detecting a rate of content change at the content source and adjusting adjusts timing of keep-alive messages sent to the mobile device based on the rate of content change. The timing of the keep-alive messages can further be determined using different polling rates for the content polls of the multiple applications on the mobile device detected by the local proxy.

Timing of keep-alive messages used in a system for mobile network resource conservation and optimization

Systems and methods for dynamic adjustment of keep-alive message intervals in a mobile network are disclosed. One embodiment of maintaining an IP connection between a mobile terminal and a network node over a network includes, detecting a rate with which the client-slide request are made from the mobile terminal, detecting a rate with which the client-slide request are made from the mobile terminal, sending, by the network node, keep-alive messages to the mobile terminal in an absence of network traffic through the IP connection between the mobile terminal and the network node, and/or further optimizing the time intervals between the keep-alive messages based on a cost to send the keep-alive messages in the network.
