| 20080244707 | WIRELESS TRANSMITTER IDENTITY VALIDATION IN A WIRELESS NETWORK - An apparatus, a method, and logic encoded in computer readable media that when executed operable to carry out the method. The method includes wirelessly receiving at a receiving station a signal transmitted from a transmitting station in a wireless network. The signal includes a network identifier, e.g., MAC address of the transmitting station. The method includes determining one or more RF waveform characteristics of at least a transient part of the received signal, decoding the received signal to determine the network identifier, e.g., MAC address, determining one or more behavior characteristics from the received signal; and using the decoded network identifier, e.g., MAC address and a combination of the one or more waveform characteristics and the one or more behavior characteristics to ascertain whether or not the network identifier, e.g., MAC address is a spoofed identifier, the ascertaining using historical samples of combinations for different network identifiers. | 10-02-2008 |
| 20080276004 | Populating Location Wiremap Databases - A method for populating location wiremap databases. In particular implementations, a method includes establishing a link layer connection with a client on a switch port, where the switch port is associated with a port identifier and is mapped to a location; identifying one or more connection attributes of the connection, where the connection attributes comprise a network layer address of the client; and transmitting the port identifier and the network layer address of the client to a location server. | 11-06-2008 |
| 20090046633 | DIGITALLY SIGNING ACCESS POINT MEASUREMENTS FOR ROBUST LOCATION DETERMINATION - In an example embodiment, a wireless client sends a probe request frame and waits for responses to the probe frame. The responses to the probe request from comprise encrypted data representative of the signal strength of the client as measured by the respondent that are digitally signed by the respondent's certificate. The client aggregates the responses and forwards them to a location based server. | 02-19-2009 |
| 20090113018 | MOBILITY SERVICE CLUSTERING USING NETWORK SERVICE SEGMENTS - Described in an example embodiment herein is a Mobility Service Engine (MSE) cluster comprising an MSE Cluster Master and at least one MSE Cluster Slave. The MSE Master is configured to define Network Service Segments. The MSE Master of the cluster distributes the Network Service Segments to slaves within the cluster. The network is configured to forward data to the correct Network Service Segment. | 04-30-2009 |
| 20090119762 | WLAN Access Integration with Physical Access Control System - A network access system. In particular implementations, a method includes monitoring, responsive to a network access request of a client, an authentication session between an authentication server and the client, and determining user credential information associated with a user of the client based on one or more messages of the authentication session. The method also includes accessing, using the user credential information, physical entry information indicating a physical location of the user relative to a defined perimeter, and conditionally allowing the client access to a network based on the physical entry information and a successful authentication of the client. | 05-07-2009 |
| 20090136027 | PROVIDING SECURE COMMUNICATIONS FOR ACTIVE RFID TAGS - Described herein in an example embodiment, is a mechanism to distribute and implement secure credentials on a WLAN (wireless local area network) employing radio frequency identification (RFID) tags. Symmetric keys are provisioned to the tag in a manner that allows for optimized re-association and secure announcements. The provisioned keys are derived in a way that enables the controller to operate without having to maintain the key state for every tag. In an example embodiment, the controller generates keys for the RFID tags that are derived from a master key associated with the controller, an identifier assigned to the RFID tag and an address associated with the RFID tag. | 05-28-2009 |
| 20090257426 | INSERTING TIME OF DEPARTURE INFORMATION IN FRAMES TO SUPPORT MULTI-CHANNEL LOCATION TECHNIQUES - A device whose location is to be determined (target device) generates a plurality of frames (messages) and time of departure (TOD) timestamp information indicating when the target device transmits the plurality of frames in a sequence or burst. The target device transmits the plurality of frames and the TOD information, wherein the plurality of frames are transmitted such that at least two of the frames are on different radio frequency (RF) channels. Within a sequence or burst (or across multiple sequences or bursts), multiple widely spaced transmissions on the same channel are included to allow for estimation of the crystal frequency offset of the transmitting device. The TOD information included in the transmitted packets allows devices that receive the packets not to change their channels of operation solely for the purpose of receiving packets from the device to be located. | 10-15-2009 |
| 20100217845 | Coordinated Reboot Mechanism Reducing Service Disruption in Network Environment - In one embodiment, a method includes identifying a plurality of network elements for reinitiation, wherein the network elements are operative to manage at least one child element; selecting a first network element from the plurality of network elements, transmitting a disable message to the first network element; determining whether the at least one child element has migrated to one or more alternate network elements; and conditionally transmitting a reinitiation message to the first network element. | 08-26-2010 |
| 20110007636 | Fault Reporting Tag for Mesh Access Points - Mesh access point fault reporting. In particular implementations, a method includes receiving a fault indication indicating one or more failures; collecting fault data related to the one or more failures or a state of the mesh access point; and passing the fault data to the RFID tag, which wirelessly transmits messages relating to the fault. | 01-13-2011 |
| 20110022676 | MOBILITY SERVICE CLUSTERING USING NETWORK SERVICE SEGMENTS - Described in an example embodiment herein is a Mobility Service Engine (MSE) cluster comprising an MSE Cluster Master and at least one MSE Cluster Slave. The MSE Master is configured to define Network Service Segments. The MSE Master of the cluster distributes the Network Service Segments to slaves within the cluster. The network is configured to forward data to the correct Network Service Segment. | 01-27-2011 |
| 20110110293 | Location tracking using response messages identifying a tracked device in a wireless network - In one embodiment, an apparatus includes a receiver configured for receiving a response message from a tracked device in a wireless network, the response message transmitted in response to a provoking message having an identifier of the tracked device in a transmitter address field, and a processor for measuring at least one location related parameter, extracting the identifier of the tracked device from the response message and identifying the response message as a location tracking message based on information in the response message. A field of the response message includes the identifier of the tracked device copied from the provoking message and the transmitter address is not provided in another field of the response message. An apparatus for location tracking is also disclosed. | 05-12-2011 |
