  • Publication number: 20160124672
    Abstract: A method for a device to optimize memory includes: when a newly created process needs to be added into a control group, detecting whether a total resource value of memory resources occupied by all processes in the control group at a current moment reaches a critical resource value; if it is detected that the total resource value of memory resources occupied by all processes in the control group at the current moment reaches the critical resource value, cancelling restriction of the predetermined resource threshold on the control group and adding the newly created process into the control group that is not restricted by the predetermined resource threshold; and performing a swap-out operation on memory resources occupied by an idle process in the control group, so that the total resource value of memory resources occupied by all processes in the control group is less than the predetermined resource threshold.

  • Publication number: 20150109983
    Abstract: A control method for a Wi-Fi device in a terminal, including acquiring, in a moving process of the terminal, first location information at a first moment, second location information at a second moment, and coverage of each of Wi-Fi access points corresponding to each of all Wi-Fi access point identifiers stored in the terminal; and triggering turning-off or turning-on of the Wi-Fi device according to that a location corresponding to the first location information and a location corresponding to the second location information are outside or within the coverage of each of the Wi-Fi access points corresponding to each of all the Wi-Fi access point identifiers stored in the terminal. In embodiments of the present invention, turning-off or turning-on of a Wi-Fi device in a terminal can be triggered according to location information of the terminal.

  • Publication number: 20140098061
    Abstract: An electronic device and a method for controlling zooming of a displayed object are disclosed. The method includes: receiving a single-point slide operation performed by a user on a displayed object of a touch screen, and generating a slide signal; parsing the slide signal to obtain a slide track and a feature value of the single-point slide operation; determining whether the feature value of at least one point in the single-point slide operation is greater than a preset value; and when the feature value is greater than the preset value, controlling zooming of the displayed object according to the slide track. A slide track and a feature value of a single-point slide operation of a user are identified, and when it is determined that the feature value is greater than a preset value, zooming of a displayed object of the touch screen is controlled.

  • Publication number: 20070086443
    Abstract: The present invention discloses a method for creating a bearer in Multimedia Broadcast/Multicast service (MBMS), including the activating process. In the method, an extended MBMS Network Service Access Point Identity (MBMS_NSAPI) and an MBMS context identity are adopted such that a user can activate more than eleven MBMS bearer services simultaneously, and avoid the complexity of manual activation. This invention provides another method for creating a bearer in MBMS, including the deactivating process of an MBMS service corresponding to the above activating process. This invention also provides a User Equipment (UE) which creates a bearer in MBMS and a Serving GPRS Support Node (SGSN) which creates a bearer in MBMS.
