摘要： 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 sever. 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 tip 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.

摘要： 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.

摘要： A method and a system of providing cellular/wireless network dual mode communication services are provided. The wireless network interface normally stays in the standby mode, and the cellular interface is closed. When receiving calls, the cellular system receives the calls and wakes up the wireless network system to communicate to the calls. Hence, the power consumption of the dual mode phone is minimized.

摘要： 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.
