  • Patent number: 8335512
    Abstract: A method of network resource release processing is provided, which includes the following steps. After user equipment (UE) using idle mode signaling reduction (ISR) mechanism registers to two 3rd Generation Partnership Project (3GPP) communication networks, when the UE changes from the 3GPP network to a non-3GPP communication network, a serving gateway (serving GW) receives a message sent from a peer endpoint network element (NE), and deletes network resources established by the two 3GPP communication networks for the UE according to the message. A mobility management NE and a serving GW are also provided. Through the method and device of network resource release processing, the resources are released when the UE using the ISR mechanism changes from the 3GPP network to the non-3GPP communication network.

  • Patent number: 8335093
    Abstract: According to the invention, a blocking oscillator type converter circuit functions with a transformator that only comprises a primary winding and a secondary winding. Said transformator does not comprise a return coupling winding for the blocking oscillator. The control voltage of the oscillator is derived from the primary voltage of the transformator during the free-wheeling phase. The invention also relates to a voltage monitoring circuit that works independently from the oscillator, the output voltage of the oscillator being repressed when the voltage on the output of the blocking oscillator is too high. A flow monitoring circuit functions independently from the oscillator and the voltage monitoring circuit and suppresses the impulses for the power transistor when the power on the output side exceeds a predetermined measurement.

  • Patent number: 8334925
    Abstract: A method and an apparatus for processing images are disclosed. The method includes: generating an image histogram of an image to be processed; judging whether the image to be processed requires backlight compensation according to the image histogram; if the image to be processed requires backlight compensation, determining a first luminance boundary value A used for deciding whether to perform backlight compensation and a second luminance boundary value C used for deciding whether to perform positive or negative backlight compensation; and performing backlight compensation for the image to be processed according to the first luminance boundary value A and the second luminance boundary value C. The method is simple and universally applicable. After backlight compensation, the contrast of the image is high, and the image is free from background overexposure and image layering. The image photographed in a backlight environment is processed properly.

  • Patent number: 8331245
    Abstract: A method and a system for Internet Protocol (IP) session keepalive monitoring, a home gateway and a network device are provided. The method includes: receiving, by a User Equipment (UE) or an IP edge node, a Bidirectional Forwarding Detection (BFD) message sent by a Home Gateway (HGW), in which a first discriminator field value included in the BFD message is a difference between an IP address prefix of the UE and an IP address prefix of the HGW; and monitoring, by the UE or the IP edge node, whether an IP session between the IP edge node and the UE is keepalive according to the first discriminator field value in the BFD message. “Multihop BFD” is used as a keepalive monitoring mechanism of a “Multihop IPv6 Session”, thereby realizing keepalive monitoring of the “Multiple hop IPv6 Session”.

  • Patent number: 8327935
    Abstract: A method for fracturing a subterranean formation penetrated by a well bore comprises formulating a fracturing fluid useful in hydrocarbon drilling having the properties of both a dispersing fracture solution and an aggregating fracture solution. In particular, the dispersing properties of the stabilizing fracture solution are able to act as a dispersing fracture fluid in the clay and earthen materials discharged from the pay zone in the flow-back fluids during hydraulic fracturing. At the same time, aggregating properties of the stabilizing solution stabilize the pay zone. This stabilization property allows the flow of hydrocarbon through the fractures for a significantly longer time than with prior art fluids.
