    摘要： A method of combined direction finding (DF) and fine timing measurement (FTM) positioning in a wireless location area network (WLAN) is proposed. A multiple antenna IEEE 802.11 transmitting device (AP) can transmit signal preamble containing multiple Long Training Field (LTF) symbols in a radio frame from multiple antennas, which allows a receiving device (STA) to resolve multiple DF sounding signals transmitted from the multiple antennas and thereby estimating angle of departure (AoD). On the other hand, the AP can estimate angle of arrival (AoA) from radio signals transmitted from the STA. When the radial resolution error of AoD or AoA positioning increases, DF positioning and fine-timing measurement (FTM) ranging can be jointly applied to reduce the radial resolution error and extends the AoD/AoA service area with positing accuracy.

    摘要： A method for transiting basic service sets (BSSs) in a wireless communications system is provided. A wireless station first detects an integrity of a real-time flow from an access point in a first BSS. The wireless station then sends a request frame to the access point. The request frame comprises a communication condition of the wireless station. The access point responds with information of a plurality of APs and a set of parameters that used to select the APs. The wireless station then determines which AP to be associated according to the information of the plurality of APs and the communication quality of the wireless station.

    摘要： 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.

    摘要： Systems and techniques for managing local communication between a network access point and a host device. Upon connection by a host device to an access point, a local connection link is established between the access point and the host device. A network connection may be established between the access point and the host device, with the network connection being able to pass through the host device to enable communication with and beyond an access network to which the access point provides a connection. Local messages may be passed between the access point and the host device over the local connection link, separately from and independent of communication that may occur over the network connection.

    摘要： 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.
