摘要： A base station (101) will instruct relay stations (102) to periodically skip transmissions of their control information when control messaging by all relay stations exceeds a predetermined threshold (e.g., 50% of radio resource capacity). The base station determines the relay stations to skip by periodically ranking the relay stations and skipping control messages for relay stations having a lowest rank.

摘要： A wireless packet communication system that enables a wireless terminal to move from one wireless LAN to another while maintaining packet communication. The, wireless terminal detects the electric field strength of a carrier signal from each base station during a back -off, period, creates move destination information based on a carrier signal having the greatest electric field strength and the IP address of the currently used base station, and transmits the created Information and IP address to a server. The server writes the IP address into an edge router connected to a base station at the move destination in accordance with the information and IP address created by the wireless terminal to ensure that the packet data from a remote party is transmitted from the base station at the move destination. In an embodiment, the address is also written into a core router for reouting to the new edge router.
摘要翻译：一种使得无线终端能够在保持分组通信的同时从一个无线LAN移动到另一个的无线分组通信系统。无线终端在退避期间检测来自每个基站的载波信号的电场强度，基于具有最大电场强度的载波信号和当前使用的基站的IP地址创建移动目的地信息，并将创建的信息和IP地址发送到服务器。服务器根据由无线终端创建的信息和IP地址将IP地址写入连接到移动目的地的基站的边缘路由器，以确保来自远端的分组数据从基站在移动目的地。在一个实施例中，地址也被写入核心路由器以用于重新路由到新的边缘路由器。

摘要： To reduce the amount of signaling traffic used by a plurality of mobile nodes positioned in a vehicle, a mobile communication system is provided with a vehicle proxy location register (VPLR). The VPLR transmits a router advertisement message containing information (PLR option), which indicates that proxy location registration can be performed. A mobile node positioned in the vehicle receives the router advertisement message, and transmits a proxy location registration request, which includes the information for requesting the VPLR to perform proxy location registration instead of directly registering a location in the server, to the vehicle proxy location register for the purpose of establishing communication between the mobile node and another communication node. This enables the mobile node positioned in the vehicle to communicate with another mobile node via the VPLR.
摘要翻译：为了减少由位于车辆中的多个移动节点使用的信令业务量，移动通信系统被提供有车辆代理位置寄存器（VPLR）。 VPLR发送包含信息（PLR选项）的路由器通告消息，其指示可以执行代理位置注册。定位在车辆中的移动节点接收路由器通告消息，并且发送代理位置注册请求，其包括用于请求VPLR执行代理位置登记的信息，而不是直接在服务器中注册位置到车辆代理位置寄存器目的是建立移动节点与另一通信节点之间的通信。这使得位于车辆中的移动节点能够经由VPLR与另一移动节点通信。
