    摘要： Certain aspects of the present disclosure relate to methods and apparatuses for handling malicious attacks. In one aspect, the methods and apparatuses are configured to identify packets received from a malicious source based at least in part on packets received by a wireless device that change a state of the wireless device from a dormant state to a connected state, selectively disconnect the wireless device from a packet data network (PDN) by releasing a first Internet Protocol (IP) address used to connect the wireless device to the PDN when a number of packets identified as received from the malicious source reaches a threshold number within a monitoring period, and reconnect the wireless device to the PDN using a second IP address that is different from the first IP address. In another aspect, a connection to an IP Multimedia Subsystem (IMS) PDN is maintained after the PDN is disconnected.

    摘要： Methods, systems, and circuits for preserving state information during power saving operations are disclosed. One example embodiment includes a circuit having a processing core, where the processing core includes logic processing circuits as well as circuits (e.g., flip-flops registers) that are used to store state information in the processing core. The logic processing circuits have power connections to a power rail that are subject to a switch, which can disconnect the power connections from the power rail. The circuits that are used to store state information have different power connections that are subject to a different switch. Therefore, the logic processing circuits and the state information circuits can be separately power-collapsed.

    摘要： A method of thermal mitigation in a device having a plurality of non-real-time processing units (PUs) and a plurality of real-time PUs, including connecting each of the plurality of real-time PUs and the plurality of non-real-time PUs to a first power supply, and performing thermal mitigation. Performing thermal mitigation includes disconnecting each of the plurality of non-real-time PUs except one of the plurality of non-real-time PUs from the first power supply resulting in an active non-real-time PU, and connecting a second power supply that derives power from the first power supply to the active non-real-time PU, wherein a voltage supplied by the second power supply is less than a voltage supplied by the first power supply.
