  • Publication number: 20120163300
    Abstract: The present invention discloses a method and system for acquiring routing strategy. In the solution of the present invention, a routing strategy provision unit sends routing strategies of local IP access to radio side network elements; the radio side network elements receive the routing strategies of local IP access. With the solution of the present invention, the radio side network elements are able to acquire the routing strategies of local IP access at the network element level or the user level, so that the radio side network elements transmit data according to the routing strategies, and the radio side network elements can effectively offload the data with the acquired routing strategies. Besides, in the solution of the present invention, the routing strategies might be for users, that is, different routing strategies might be made for different users, thereby improving the user experience and promoting generalization and popularization of services.

  • Publication number: 20120142278
    Abstract: The present invention provides a method and system for indicating data offload, and a traffic offload network element, the method comprises: when a radio bearer is established or modified, a mobility management unit of a core network notifies a traffic offload network element of the bearer type of the bearer to determine whether to start the data offload. Through the present invention, the judgment operation of the core network is simplified. In addition, under the situation that the core network side determines whether to start local access function, the traffic offload network element also can correctly start an offload policy.

  • Publication number: 20120117257
    Abstract: The invention discloses a method for notifying connection attributes of local IP access, comprising in the procedure of establishing a PDN connection, a mobility management element notifying the user terminal of connection attributes of the PDN connection. The invention also discloses an apparatus for notifying connection attributes of local IP access, comprising: a determination unit for determining connection attributes of the PDN connection for user terminal in the process of establishing the PDN connection; a notification unit for notifying the user terminal of the connection attributes of the PDN connection. The mobility management element at the network side of the invention notifies the UE of the type and attribute information of the PDN connection at the same time after determining the PDN connection to be established for UE so as to facilitate the UE determining the corresponding access policy according to the attribute information of current PDN connection when moving.

  • Publication number: 20120023341
    Abstract: A power supply circuit includes a power controller and a switch. The power controller is connected to a Southbridge chip of a motherboard. The Southbridge chip outputs status signals of the motherboard. The power controller provides a +5V_SYS voltage or a +5V_SB voltage to a universal serial bus (USB) connector according to the status signals. The switch is connected to the USB connector, a USB controller, and the Southbridge chip. The switch connects or disconnects from the USB connector and the USB controller according to the status signals.

  • Publication number: 20090154808
    Abstract: A method for segmenting an object region of interest from an image includes detecting each corner in a captured image; acquiring edges of the object from the captured image based on the detected corners; clustering the detected corners based on corners on the acquired edges; and segmenting the image region in the captured image formed by the clustered corners as a region of interest that likely includes the object. With this method and apparatus for the method, an object region of interest may be segmented from an image without utilizing features such as an object shadow and edges.
