    摘要: The present invention is directed to an apparatus and method for IP mobility management for persistent connections. Without affecting the applications on the network domain, it provides for domain hand-off for a mobile node so that the mobile node can maintain the persistent connection. The mobility management apparatus may comprise a Mobility-Aware Socket module (MAS) and one or more mobility management servers. Each mobility management server communicates with a corresponding mobile node. When a mobile node roams from a first network domain to a second network domain, the mobile node and its target mobile nodes execute the MAS module to support the mobility management for persistent connections through their corresponding mobility management servers.

    摘要: This invention provides a method and apparatus that uses a mobility management server (MMS) device for supporting mobility management in wireless networks. With the MMS device for services of resource management and packet relay, this invention speeds up the handover procedure for a mobile device switching from a first network domain to a second network domain in a wireless network environment having a session initiation protocol (SIP) server. When the mobile device needs to switch to the second network domain, the MMS allocates the required resources for packet relay, provides the related information for the second network domain, and takes care of the packet relay. This invention shortens the inter-domain handover latency and reduces the number of lost packets during the handover procedure. Thereby, the transmission efficiency of the present invention meets the requirement for real-time multimedia applications.

    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 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.

    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.
