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： 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.
摘要翻译：本发明提供一种使用移动性管理服务器（MMS）设备来支持无线网络中的移动性管理的方法和装置。利用用于资源管理和分组中继服务的MMS设备，本发明加速了具有会话发起协议（SIP）服务器的无线网络环境中移动设备从第一网络域切换到第二网络域的切换过程。当移动设备需要切换到第二个网络域时，MMS为分组中继分配所需的资源，为第二个网络域提供相关信息，并对分组中继进行处理。本发明缩短了跨域切换等待时间并减少了切换过程中的丢包数量。因此，本发明的传输效率满足实时多媒体应用的要求。
