    • The invention relates to a method for configuring an IP address of a mobile node attaching to a first access network during an inter-access technology handover from another, second access network. Moreover, the invention relates to a mobile access gateway and a mobile node that participate in this method. First and second access network belong to a network domain offering a network-based mobility function. In order to detect whether a mobile node implements a network-based mobility function a virtual interface discovery is performed by checking whether the mobile node also configures the address according to the home network prefix offered to the mobile node before the handover on its interface to the first access network. In parallel, an address configuration is performed. Based on the detection of whether a virtual interface is implemented at the mobile node, the mobile access gateway may decide whether to use network-based mobility or client-based mobility and change the address configuration.
    • 本发明涉及一种用于在从另一个第二接入网络的接入间技术切换期间配置附着到第一接入网的移动节点的IP地址的方法。 此外,本发明涉及参与该方法的移动接入网关和移动节点。 第一和第二接入网络属于提供基于网络的移动性功能的网络域。 为了检测移动节点是否实现基于网络的移动性功能,通过检查移动节点是否在切换之前根据提供给移动节点的归属网络前缀在其接口上配置地址来执行虚拟接口发现 第一接入网络 并行地,执行地址配置。 基于在移动节点处是否实现虚拟接口的检测,移动接入网关可以决定是使用基于网络的移动性还是基于客户机的移动性并且改变地址配置。
