    • Seamless communication handoff is achieved by establishing a protocol tunnel to route leftover packets between network access nodes during the handoff. For example, in a mobile IP-based system, a mobile node may perform a handoff from a first access node that is associated with a first routing node to a second access node that is associated with a second routing node. To prevent the loss of any packets that may be in route for delivery to or from the first routing node during the handoff, the mobile node establishes a protocol tunnel with the first access node via the second access node. On the forward-link, packets being delivered from the first routing node are routed over the protocol tunnel to the second access node and then to the mobile node. On the reverse-link, packets being sent to the first routing node are routed over the protocol tunnel from the mobile node to the second access node and then to the first routing node. In conjunction with these operations, the mobile node concurrently maintains separate IP interfaces for the routing nodes. In addition, steps are taken to ensure that packets are routed to the appropriate IP interface during the handoff.
    • 无缝通信切换是通过建立协议隧道来实现的,该协议隧道在切换过程中在网络接入节点之间路由剩余分组。 例如,在基于移动IP的系统中,移动节点可以执行从与第一路由节点相关联的第一接入节点到与第二路由节点相关联的第二接入节点的切换。 为了防止在切换期间传输到或来自第一路由节点的路由中的任何分组的丢失,移动节点经由第二接入节点与第一接入节点建立协议隧道。 在前向链路上,从第一路由节点递送的分组通过协议隧道路由到第二接入节点,然后传送到移动节点。 在反向链路上,发送到第一路由节点的数据包通过协议隧道从移动节点路由到第二接入节点,然后被路由到第一路由节点。 结合这些操作,移动节点同时为路由节点维护单独的IP接口。 此外,采取步骤确保在切换期间将数据包路由到相应的IP接口。

    • An authentication server may be adapted to (a) authenticate an authentication peer seeking to establish communications via a first network access node; (b) retrieve user profile information associated with the authentication peer; and/or (c) send the user profile information to a network gateway node that facilitates communication services for the authentication peer. A PMIP network node may be adapted to (a) provide wireless network connectivity to an authentication peer via a first network access node; (b) provide a PMIP key to both ends of a PMIP tunnel between the first network access node and a PMIP network node used to provide communications to the authentication peer; (c) provide the PMIP key to a first authenticator associated the first network access node; (d) receive a request at the PMIP network node from a requesting entity to reroute communications for the authentication peer; and/or (e) verify whether the requesting entity knows the PMIP key.
    • 验证服务器可以适于(a)认证通过第一网络接入节点建立通信的认证对等体; (b)检索与认证对等体相关联的用户简档信息; 和/或(c)将用户简档信息发送到有助于认证对等体的通信服务的网络网关节点。 PMIP网络节点可以适于(a)经由第一网络接入节点向认证对等体提供无线网络连接; (b)在第一网络接入节点和用于向认证对等体提供通信的PMIP网络节点之间的PMIP隧道的两端提供PMIP密钥; (c)将PMIP密钥提供给与第一网络接入节点相关联的第一认证器; (d)从所述PMIP网络节点从请求实体接收对所述认证对等体重新路由通信的请求; 和/或(e)验证请求实体是否知道PMIP密钥。
