Abstract:
A method for controlling a first interface and a second interface installed on a mobile node is provided, wherein the mobile node communicates with a first access network (AN) through the first interface and communicates with a second AN through the second interface. The method comprises following steps. A first IP address is acquired through the first interface and the first AN for accessing a service network (SN). A second IP address is acquired through the second interface and the second AN for accessing the SN. The first interface is then selected as an awake interface. The second bridging node is directed to create and cache binding information indicating a binding of the second IP address to the first IP address. The second interface is turned off after the binding information is successfully created and cached on the second bridging node.
Abstract:
A method for providing a multicast and broadcast service (MBS) by transmitting a plurality of data frames in a wireless network. The method includes: generating a first MBS data information element (MBS-DATA-IE) in a first one of the data frames, the first MBS-DATA-IE including information relating to a logical channel of the MBS, and indicating a location of an MBS map (MBS-MAP) in a second one of the data frames; determining ones of the data frames between the first and second ones of the data frames in which to add a plurality of extra MBS-DATA-IEs; and generating the extra MBS-DATA-IEs, the extra MBS-DATA-IEs being generated in the determined ones of the data frames and including information relating to the logical channel.
Abstract:
A power monitoring device for identifying the state of an electric appliance based on user feedbacks and a power monitoring method thereof are provided. The power monitoring device includes a measurement module, a variation detection and search module, and an electric appliance signature database established based on user feedbacks. When the measurement module detects a variation of a power consumption feature, the variation detection and search module searches the electric appliance signature database according to the variation to obtain electric appliances similar to the variation and the states thereof. A user contributes data to the electric appliance signature database by confirming the search result, or selecting the correct electric appliance and the state thereof. When the user confirms the search result, the power monitoring device establishes an association between the electric appliance and its electric appliance signatures and updates the electric appliance signature database.
Abstract:
Disclosed is a load balancing apparatus and method in wireless network hotspots, which comprises a resource allocation module and a load balancer. The resources reallocation module establishes the resources module and the relationship between access points (APs) and STAs in the wireless network hotspots, and seeks possible load balance shift paths (LBSPs). From these possible LBSPs, an LBSP is selected. Based on the selected LBSP, the load balancer reallocates network resources and dynamically arranges the load among the APs in the wireless network hotspots. This invention can be applicable to a centralized or a decentralized wireless communication system.
Abstract:
A re-allocation method for a distributed GGSN system. The re-allocation method includes a GGSN controller to determine a GGSN re-allocation for at least one mobile station. The GGSN re-allocation for the mobile station is performed by a GGSN or a SGSN originally connected to the mobile station, thereby enabling GGSN(s) with dynamic load balance and improving the system scalability.
Abstract:
A method and system capable of providing mobility support for IPv4/IPv6 inter-networking to a mobile node is disclosed. The mobile node in the system has an address mapper, an IPv4 protocol stack and an IPv6 protocol stack in the network layer. When moving from IPv4 to IPv6 networks, the mobile node registered an IPv4 address receives router advertisement packets from an IPv6 router, so as to obtain a IPv6 care-of-address, and resolve the IPv6 care-of-address by an IPv4 care-of-address. The address mapper issues an IPv4 message to register the IPv4 care-of-address. When moving from IPv6 to IPv4 networks, the mobile node registered an IPv6 address receives agent advertisement messages from a foreign agent, so as to obtain an IPv4 care-of-address, resolve the IPv4 care-of-address by an IPv6 care-of-address. The address mapper issues an IPv6 message to register and update binding information by the IPv6 care-of-address.
Abstract:
A method and system for detecting an appliance based on users' feedback information, particularly a nonintrusive load monitoring method and system based on a user's feedback information and a joint strategic decision search algorithm are disclosed. By means of obtaining the users' feedback information on an appliance inputted by users or a search result of the appliances being confirmed by the users to generate a mapping between the model of the appliances and at least one load signature of each model of appliances; the users' feedback information is recorded into a smart meter or a cloud computing system, and a mathematical analysis is further used to compute an occurrence of any one signature of the appliance and the identification rate of each signature; then the joint strategic decision search algorithm automatically identifies various models of appliances and analyzes the operating states of the electric appliances in homes or offices.

Abstract:
A system and method for reducing call establishment delay in wireless network is provided, in which a network node establishes a call to a wireless terminal controlled by an AP via a server. The wireless terminal notifies the server of its listen interval. In the power saving mode, the wireless terminal wakes up every listen interval and listen the beacon to check whether any buffered packet for it. When the wireless terminal learns from the beacon that there are packets waiting, it communicates with the access point to retrieve them. The server records a listen time at which the wireless terminal will wake up and listen to the AP based on the listen interval. When a network node calls the wireless terminal, the server buffers the request for a time interval based on the listen time, and then sends the request to the wireless terminal.
Abstract:
This invention discloses a data inquiry system for three-dimensional location-based image, video, and information, which comprises a client device and a remote server. The client device provides space parameters and lens parameters to the remote server through a transmission module. The remote server determines a space inquiry range by the space parameter and lens parameter, inquires an object data of an object space position parameter at the space inquiry range, shows the object data in an image data displayed by the client device to facilitate users to identify the desired viewing object, and further inquires the object data and related image and/or video data.
