    • A security gateway/home agent controller HAC is used to assign one home agent HA from a plurality of HAs and to identify at least one security protocol that is common between a mobile node MN and the assigned HA. Establishment of a security association between the MN and the assigned HA is enabled according to the identified security protocol and utilizing bootstrapping parameters provided over a secure connection between the security gateway/HAC and the MN. The bootstrapping parameters include at least a home address for the MN, an address of the assigned HA and security credentials and security parameters for the identified at least one security protocol. In an exemplary embodiment the home address for the MN may be an IPv6 home address and the MN may have certain capabilities with respect to security protocols and ciphering suites which the MN sends to the security gateway.
    • 安全网关/归属代理控制器HAC用于从多个HA分配一个归属代理HA,并且识别在移动节点MN和所分配的HA之间共同的至少一个安全协议。 根据所识别的安全协议并利用通过安全网关/ HAC与MN之间的安全连接提供的引导参数来实现MN与所分配的HA之间的安全关联的建立。 引导参数至少包括MN的归属地址,所分配的HA的地址和用于所识别的至少一个安全协议的安全凭证和安全参数。 在示例性实施例中,MN的归属地址可以是IPv6家庭地址,并且MN可以具有关于MN向安全网关发送的安全协议和加密套件的某些能力。

    • Positioning and/or navigation of an electronic device within a building when GPS signals are unavailable is provided. The electronic device scans for available Wireless Local Area Network (WLAN) Access Points (APs) upon, e.g., entering a building. The electronic device detects a signal (e.g., beacon) from at least one available WLAN AP, whereupon the electronic device retrieves the indoor location of the available WLAN AP. The location information can be directly downloaded from the WLAN AP while in state-1 via, e.g., a Native Query Protocol which includes an extension to currently defined Native Query info elements that returns location information. Alternatively, the Media Access Control (MAC) address of the WLAN AP can be read from the beacon signal, which is then used to retrieve the location of the WLAN AP from an associated database. Additionally, various embodiments may be implemented with or via a mapping application or service, where the mapping application is able to display any floor's floor plan of a building and determine/obtain the position of the electronic device inside the building relative to the floor plan.
    • 提供GPS信号不可用时,建筑物内电子设备的定位和/或导航。 电子设备例如在进入建筑物时扫描可用的无线局域网(WLAN)接入点(AP)。 电子设备检测来自至少一个可用的WLAN AP的信号(例如,信标),于是电子装置检索可用的WLAN AP的室内位置。 该位置信息可以从WLAN AP直接下载,而在通过,例如,目前以限定的原生查询协议,它包括一个扩展原生查询信息元素状态-1,返回的位置信息。 可替换地,WLAN AP的媒体接入控制(MAC)地址可以从信标信号,然后将其用于从相关联的数据库中检索WLAN AP的位置来读出。 另外,各种实施例可以通过映射应用或服务来实现,其中映射应用能够显示建筑物的任何楼层的平面图,并且相对于平面图确定/获得建筑物内的电子设备的位置。
