    Abstract: In a data communication network, data route changes happen frequently due to various reasons. For the path specific resource management signaling, such route changes would trigger large amount of signaling actions. Some of the signaling action requires a complicated process and may take a long time. This may cause service interruption in extreme cases. This invention proposed a method for signaling state management along the old data path to achieve fast signaling state re-establishment. Instead of removing the signaling states along the old data path explicitly or by time-out, the invention preserved the signaling state along the old data path with reduced state management. In the reduced state management, network resources that are held by the states along the old data path are released and minimum information is retained. The states become “dormant” states that do not require active monitoring from the network. When the old path is in use again, the states could be restored and network resources be re-allocated fast. This would be much faster than re-establishing the whole state from scratch. This invention also provides a method for fast recovery from transient route changes by allowing the signaling aware nodes at the crossover point of the data path to monitor the status of old path. This way, the signaling system could quickly re-establish the necessary state along the old path once it's found available again.

    Abstract translation: 在数据通信网络中，由于各种原因，数据路由变化频繁发生。 对于路径特定资源管理信令，这种路由变化将触发大量的信令动作。 一些信令动作需要一个复杂的过程，可能需要很长时间。 这在极端情况下可能导致服务中断。 本发明提出了一种用于沿着旧数据路径信令状态管理以实现快速信令状态重建的方法。 本发明不是明确地或通过超时去除沿着旧数据路径的信令状态，而是通过减少状态管理来保持沿着旧数据路径的信令状态。 在缩减状态管理中，释放由旧数据路径中的状态保持的网络资源，并保留最小信息。 状态变成“休眠”状态，不需要从网络进行主动监视。 当旧路径再次使用时，可以恢复状态并快速重新分配网络资源。 这将比从头开始重新建立整个状态要快得多。 本发明还提供了一种通过允许在数据路径的交叉点处的信令感知节点监视旧路径的状态来从瞬态路由改变快速恢复的方法。 这样，信号系统一旦找到再次可用就可以快速重建沿着旧路径的必要状态。

    Abstract: By introducing a hierarchical encryption scheme and the use of asymmetric cryptography, the critical information in message exchanges is concealed from unauthorized entities. This helps greatly in preventing man-in-the-middle attacks faced by inter-working. In addition, access control is conducted by introducing a network structure having a rule interpreter that is capable of mapping general rules to WLAN specific commands. It obviates the needs for mobile user's home network to understand information about every WLAN it is inter-worked with. A common interface independent of WLAN technologies could be used by the home network for all the WLANs. The above conception provides a solution to the problems of the protection of user identification information and access control in the inter-working of WLAN.

    Abstract: The present invention provides a method and system for efficiently scheduling wireless LAN traffic, giving the network the ability to serve both real-time and non-real time applications concurrently, while maintaining a requested level of quality of service for the real time application. It describes a method for scheduling quality of service traffic and a method to optimize this schedule thereby reducing the overall amount of time that is required for serving quality of service traffic (which is coordinated by a centralized network coordinator entity) and increasing the bandwidth available for non-real-time traffic. One application of such a scheduler would be WLANs that carry AV streams, such as may be found in a home based WLAN. Furthermore, a method is provided for announcing the schedule to all nodes in a wireless network to, for example, implement a power savings feature, thereby optimizing battery life and reducing the size and weight of portable network access terminals.

    Abstract: A method where home agents dynamically communicate their availability to serve as alternate home agents to each other, and a technology where the registered home agent proactively informs the mobile node to switch home agents are disclosed. According to the technique, a home agent (1000) has new functional blocks to detect the presence of an affiliated roaming mobile node and proceeds to advise the designated home agent of the mobile node regarding their availability. When the registered home agent decides to handover a mobile node, the available alternate home agents are sorted according to the metric of hop count distance and the highest valued is selected so that an available alternate home agent is assigned. A specially formatted mobility option is sent to the mobile node in order to direct it to register to the newly selected alternate home agent.
