    • A method of finding a mobile wireless communications device when an Internet Protocol (IP) packet from a remote user is sent to the device over an IP network. The mobile device does not have to register with the IP network in order to receive the IP. The method comprises the steps of receiving the IP packet at a home agent associated with a wireless communications network. The IP packet includes an IP address assigned to the device. If there is no current mobility binding record for the mobile device, instead of dropping the packet the home agent sends an access-request packet, containing the IP address, to an authentication server. The authentication server, e.g., a RADIUS server, maintains a table mapping the IP address for the device to an identification number uniquely associated with the device, such as the device's International Mobile Subscriber Identity number. The authentication server sends an access-accept packet to the home agent in the event that the device is authorized to receive the IP packet, in which case the access-accept packet includes the identification information. The home agent uses the identification number to locate, page and automatically connect the wireless device to the IP network via an InterWorking Unit (IWU) configured as a IP network access server.
    • 当来自远程用户的因特网协议(IP)分组通过IP网络发送到设备时,找到移动无线通信设备的方法。 移动设备不必向IP网络注册,以便接收IP。 该方法包括以下步骤:在与无线通信网络相关联的归属代理处接收IP分组。 IP分组包括分配给设备的IP地址。 如果移动设备没有当前的移动性绑定记录,则代理丢弃该分组,归属代理将包含该IP地址的接入请求分组发送到认证服务器。 认证服务器(例如,RADIUS服务器)维护将设备的IP地址映射到与设备唯一相关联的标识号码(例如设备的国际移动订户身份号码)的表格。 在设备被授权接收IP分组的情况下,认证服务器向归属代理发送接入接受分组,在这种情况下,接入分组包括标识信息。 归属代理使用识别号码通过配置为IP网络接入服务器的互通单元(IWU)来定位,寻呼和自动将无线设备连接到IP网络。

    • A network access server providing remote access to an IP network for a remote client initiates a PPP connection for a remote client quickly, and without requiring renegotiation of Link Control Protocols and Network Control Protocols. The network access server has a PPP session with the remote client go dormant, for example when the user is a wireless user and goes out of range of a radio tower and associated base station. The network access server does not get rid of the PPP state for the dormant session, but rather switches that PPP state to a new session, such as when the client moves into range of a different radio tower and associated base station and initiates a new active session on the interface to the wireless network. The switching of PPP states may be within a single network access server, or from one network access server to another. This "context switching" of the active PPP session allows the mobile user to seamlessly move about the wirelss network without having to re-negotiate Link Control Protocols and Network Control Protocols every time they move out of range of one radio tower and into range of another.
    • 提供对远程客户端的IP网络的远程访问的网络访问服务器快速启动远程客户端的PPP连接,并且不需要重新协商链路控制协议和网络控制协议。 网络接入服务器与远程客户端进行PPP会话休眠,例如当用户是无线用户并超出无线电塔和相关基站的范围时。 网络访问服务器不能摆脱休眠会话的PPP状态,而是将PPP状态切换到新会话,例如当客户端移动到不同无线电塔和相关联的基站的范围内并启动新的活动 会话在无线网络的接口。 PPP状态的切换可以在单个网络接入服务器内,或者从一个网络接入服务器到另一个。 活动PPP会话的这种“上下文切换”允许移动用户无缝地移动有线网络,而不必在每次移动超出一个无线电塔的范围并进入另一个无线电塔的范围时重新协商链路控制协议和网络控制协议 。
