摘要： The invention relates to a method and system for managing a communication between a first mobile network element and a second network element, wherein the communication is performed via a network on a packet-switched basis with acknowledgment messages acknowledging receipt of packets being returned to the packet sending network element. A congestion control is provided for controlling the number of packets being allowed to be sent before receipt of acknowledgment messages for these packets. The congestion control is adapted to change, when the first network element performs a hand-over and sends a message informing on the I hand-over, so as to provide faster recovery rate after handover as compared to the normal recovery rate after packet loss. At least one of the first and second network element is adapted, when receiving the message, to trigger the invocation of a fast retransmit and fast recovery algorithm. As an alternative, in order to provide the faster recovery rate after handover, a congestion window size may be step-wise increased after handover, or a threshold value defining a change from exponential to linear increase of the congestion window size, may be set to a value which is more than one half of the window size value before handover.

摘要： Applications running on a mobile device are monitored for suspicious actions utilizing mobile features of the mobile device. Once a suspicious action performed by an application is detected, that suspicious action is suspended. Information about the suspicious action and the application is collected and transmitted to a remote security system over a wireless network. The security system analyzes the suspicious action and the application to determine a security rating of the application, and transmit the security rating back to the mobile device. Whether the application is malware and whether the suspicious action should be allowed to continue are both determined based on the security rating.

摘要： A method and system for controlling a transmission window size, wherein a transmission condition of the transmission path between a transmitting element and a receiving element is checked when at least one of the transmitting and receiving elements moves from a first access network to a second access network. Then, the transmission window size is changed in response to the result of said checking step. Thereby, the transmission window can be decreased actively to thereby accelerate the control procedure and improve resource utilization.
