  • Publication number: 20170070893
    Abstract: A method of direction finding (DF) positioning in a wireless location area network (WLAN) is proposed. A multiple antenna IEEE 802.11 transmitting device can transmit signal preamble containing multiple Long Training Field (LTF) symbols in a radio frame from multiple antennas simultaneously, which allows a receiving device to resolve multiple DF sounding signals transmitted from the multiple antennas. As a result, angle of departure (AoD) of the transmitting device can be estimated by using the multiple resolved DF sounding signals from each antenna for DF positioning purpose.

  • Publication number: 20170070950
    Abstract: 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.

  • Patent number: 9577984
    Abstract: 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.

  • Publication number: 20160366548
    Abstract: 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.

  • Patent number: 9451472
    Abstract: An approach is provided for providing a WiFi network information service. A configuration client processes and/or facilitates a processing, by at least one module of at least one access point, of configuration data stored at the at least one access point to determine network information. The configuration client then causes a transmission of the network information by the at least one module to at least one server. A location client also determines at least one request, from at least one client, for network information associated with at least one access point, at least one location, or a combination thereof. The location client then processes and/or facilitates a processing of the at least one request to cause a generation of at least one query for the network information from at least one server, wherein the network information is determined from at least one module of the at least one access point.

  • Publication number: 20160197922
    Abstract: An approach is provided for performing authentication in a communication system. In one embodiment, a key is established with a terminal in a communication network according to a key agreement protocol. The agreed key is tied to an authentication procedure to provide a security association that supports reuse of the key. A master key is generated based on the agreed key. In another embodiment, digest authentication is combined with key exchange parameters (e.g., Diffie-Hellman parameters) in the payload of the digest message, in which a key (e.g., SMEKEY or MN-AAA) is utilized as a password. In yet another embodiment, an authentication algorithm (e.g., Cellular Authentication and Voice Encryption (CAVE)) is employed with a key agreement protocol with conversion functions to support bootstrapping.

  • Patent number: 9231759
    Abstract: The invention relates to a method of authenticating a user equipment in a communications network. The method involves sending a message from a network entity to the user equipment. This message includes a set of options for an authentication procedure for authenticating an internet protocol communication over a first interface between the user equipment and the network entity; said options including a “shared key”-based authentication procedure. The method also involves selecting an option from the set. In the event that the “shared-key”-based authentication procedure is selected, a shared secret from a security key established in a generic bootstrapping architecture (GBA) is generated over a second interface between the user equipment and a bootstrapping service function. The shared secret is then used to compute and verify authentication payloads in the key-based authentication procedure for the communication over the first interface.

  • Publication number: 20150365805
    Abstract: A method of indoor positioning using Fine Timing Measurement (FTM) avoiding co-located access point (AP) is proposed. In a wireless local area network, an AP obtains neighboring AP location information and determines a list of co-located BSSIDs. In a first option, an STA first selects an AP and query for AP location and co-located BSSID information using ANQP (Access Network Query Protocol). In a second option, the STA first selects an AP and initiates FTM protocol with the selected AP and thereby obtaining AP location and co-located BSSID information. Upon obtaining the AP location and the co-located BSSID list, the STA can initiates FTM protocol with additional non-co-located BSSs for determining an accurate STA location.

  • Publication number: 20150365952
    Abstract: A method of managing BSS network loading is proposed. An access point (AP) transmits BSS session time and data limit element in beacon or probe response frame or a response frame to a service request frame. The AP determines the session time and data limit according to the network load and AP resourced. The AP adjusts the session time and data limit dynamically. An STA decides whether to join a specific BSS based on the BSS session time and the BSS session data limit. AP encourages or discourages the STA to join the BSS by increasing or reducing the session time and data limit. The per-AP loading will be distributed according to AP's capabilities.
