摘要： A mechanism by which handoff delay can be minimized while not compromising the IMS/MMD security and also protecting the media if required by certain applications is presented. One proactive method includes proactive authentication. Another proactive method includes proactive security association, such as transferring SA keys from old proxy to new proxy, or transferring keys through serving signal entities. Reactive methods include transferring SA keys from old proxy to new proxy, using either push or pull technology. Other reactive methods include transferring keys through serving signal entities using either push or pull technology.

摘要： An apparatus for providing security to media independent handover service includes a point of service for providing the media independent handover services including an independent authenticator. The independent authenticator authenticates candidate access networks prior to the handover of the mobile devices from serving access networks to the candidate access networks, where each of the serving access networks and the candidate access networks belong to a plurality of heterogeneous access networks having the specific serving media. An access controller applies an access control through an access authentication with the point of service providing the media independent handover services through an authentication server, in which when the access authentication is established between the point of service and the authentication server, the mobile devices are authorized to access the media independent handover services through the point of service for the mobile devices attached between heterogeneous media.

摘要： The present invention advantageously provides several systems and methods for solving the trombone routing issues within an IMS/MMD network. These approaches avoid trombone routing, speed up handoff, and increase the efficiency of signaling and overall performance of an IMS/MMD network. These solutions can broadly be divided into the following categories. Piggy-backing SIP registration over MIP (Split at FA); Selective Reverse Tunneling and Tunneling between FA and P-CSCF; the SIP-based mobility protocol; use of CoA during SIP registration and call up in MIPv6; Piggy-backing SIP registration when HA and S-CSCF Co-exist; Using Dynamic Home Agents in MIPv4 FA-CoA; and the Interceptor-Caching Approach.
摘要翻译：本发明有利地提供了用于解决IMS / MMD网络内的长号路由问题的几种系统和方法。这些方法避免了长号线路路由，加速切换，并提高了IMS / MMD网络的信令效率和整体性能。这些解决方案可以大致分为以下几类。通过MIP支持SIP注册（在FA中分拆）; FA和P-CSCF之间的选择性反向隧道和隧道; 基于SIP的移动协议; SIP注册期间使用CoA并在MIPv6中调用; 当HA和S-CSCF共存时，捎带SIP注册; 在MIPv4 FA-CoA中使用动态归属代理; 和拦截器缓存方法。
