    • This disclosure provides systems, methods and apparatus for non-optimized handoffs for wireless communication. For example, the disclosure may be applied to enhance non-optimized handoff from a long-term evolution (LTE) network to an evolved high rate packet data (eHRPD) network. Systems, methods, and apparatus for reducing the interruption gap during handoffs from an LTE radio access network to an eHRPD network are also discussed. In one aspect, a method is provided for communicating information associated with a handoff of a wireless device from a source network to a target network. The method includes fetching a context for a device communicating via a first radio access system of a first network based in part on a unique identifier from a second radio access system of a second network.
    • 本公开提供了用于无线通信的非优化切换的系统,方法和装置。 例如,可以应用本公开来增强从长期演进(LTE)网络到演进的高速率分组数据(eHRPD)网络的非优化切换。 还讨论了用于减少从LTE无线电接入网到eHRPD网络的切换期间的中断间隙的系统,方法和装置。 在一个方面,提供了一种用于将与无线设备的切换相关联的信息从源网络传送到目标网络的方法。 该方法包括通过部分地基于来自第二网络的第二无线电接入系统的唯一标识符来获取通过第一网络的第一无线电接入系统进行通信的设备的上下文。

    • The invention is a new protocol for securing the communication link between the Home Agent and the Mobile Node. A cipher key and an integrity key are generated at a home AAA server and are also generated independently at the Mobile Node. The two keys generated at the home AAA server are transmitted to the Home Agent to secure information packets transmitted between the Mobile Node and the Home Agent. The cipher key and integrity key are used to establish a security association used for information packet transmissions. The cipher key is used to encrypt the information packets, and the integrity key is used to ensure that the contents of the encrypted message are not altered.
    • 本发明是用于保护归属代理和移动节点之间的通信链路的新协议。 在家庭AAA服务器处生成密钥和完整性密钥,并且还在移动节点处独立生成。 在家庭AAA服务器处产生的两个密钥被发送到归属代理以保护在移动节点和归属代理之间传送的信息包。 密钥和完整性密钥用于建立用于信息包传输的安全关联。 密钥用于加密信息包,完整性密钥用于确保加密消息的内容不被更改。
