    • A method of establishing communication protocols between a mobile node and a home agent in a mobile communications networks. The method comprising the steps of: generating, at the mobile node plural care of addresses (CoAs) and a corresponding numberof security parameter indices; sending the generated CoAs and security parameter indices to the home agent in an encypted form; generating, at the home agent, on the basis of the received CoAs and security parameter indices, an equal number of home addresses (HoAs) and associated security parameter indices; sending the list of HoAs and associated security parameter indices generated at the home agent to the mobile node, and; using the generated CoAs, HoAs and associated security parameter indices as the basis for communication protocol addresses and encryption for communication between the home agent and the mobile node. A system employing the method is also provided.
    • 一种在移动通信网络中在移动节点和归属代理之间建立通信协议的方法。 该方法包括以下步骤:在移动节点处生成多个地址(CoAs)和相应数量的安全参数索引; 将所生成的CoA和安全参数索引以指定的形式发送到归属代理; 在归属代理处基于所接收的协议和安全参数索引,相同数量的归属地址(HoAs)和相关的安全参数索引来生成; 将归属代理产生的HoAs列表和相关的安全参数索引发送给移动节点; 使用生成的CoAs,HoAs和相关的安全参数索引作为通信协议地址的基础和用于归属代理和移动节点之间的通信的加密。 还提供了采用该方法的系统。

    • The present invention relates to an access unit (21) for coupling a plurality of subscribers (usr1,usr2) to a data communication network (30), and comprising an auto-configuration control unit (123) adapted to learn, from first auto-configuration data issued by an auto-configuration server (23) and transiting through said access unit towards a particular subscriber coupled to said access unit, a particular network address (IP@1) as being dynamically assigned to said particular subscriber.
      An access unit according to the invention is characterized in that said auto-configuration control unit is further adapted to learn, from second auto-configuration data transiting through said data communication network, said particular network address as being newly assigned to another subscriber, and in that said access unit further comprises an auto-configuration preemption unit (122) coupled to said auto-configuration control unit, and adapted thereupon to issue an auto-configuration control signal towards said particular subscriber, whereby a new auto-configuration session is initiated between said particular subscriber and said auto-configuration server, and further whereby a new network address (IP@2) is dynamically assigned to said particular subscriber.
    • 本发明涉及用于将多个用户(usr1,usr2)耦合到数据通信网络(30)的接入单元(21),并且包括自动配置控制单元(123),适于从第一自动配置 配置数据由自动配置服务器(23)发布并通过所述接入单元转发到耦合到所述接入单元的特定用户,特定网络地址(IP @ 1)被动态分配给所述特定用户。 根据本发明的访问单元的特征在于,所述自动配置控制单元还适于从第二自动配置数据通过所述数据通信网络学习所述特定网络地址作为新分配给另一用户,并且 所述访问单元还包括耦合到所述自动配置控制单元的自动配置抢占单元(122),并且随后对所述特定用户发出自动配置控制信号,由此在 所述特定用户和所述自动配置服务器,并且进一步地,新的网络地址(IP @ 2)被动态分配给所述特定用户。
