Patent application numberDescriptionPublished
20080207278Mobile platform tracking in wireless networks - A mobile station in a wireless network provides a presence indication when in a power saving state. The presence indication is sent periodically, and the period is dependent on whether the mobile station is stationary or in motion. The period may also be dependent on an asset protection level of the mobile station.08-28-2008
20080220769Wake-on-WLAN for stationary wireless stations - Stationary wireless network stations are woken up using Wake-on-WLAN functionality. Wake-on-WLAN is provided by paging stations in a wireless network. Paging may support mobile stations across multiple access points. Paging may also support stationary nodes with reduced overhead. Wake-on-WLAN is also provided to stationary stations in idle mode by signifying a wake-on event in a traffic indication map (TIM). Wake-on events may occur when a station is associated or disassociated with an access point. Upon receiving a wake-on event, a station associates or reassociates with an AP if necessary.09-11-2008

Wake-on-WLAN is also provided to stationary stations in idle mode by signifying a wake-on event in a traffic indication map (TIM). Wake-on events may occur when a station is associated or disassociated with an access point. Upon receiving a wake-on event, a station associates or reassociates with an AP if necessary.09-11-2008
20090034443POWER SAVING IDLE MODE ALGORITHM FOR AN ACCESS POINT - A wireless device operating as an access point (AP) uses an idle mode service and an idle mode mechanism to provide the capability of powering down during idle times. The client and the AP may share a cooperative idle mode mechanism to efficiently manage power for all devices operating in the WLAN.02-05-2009
20090185536Apparatus, system and method capable of pre-allocating and communicating IP address information during wireless communication - An embodiment of the present invention provides an apparatus, comprising a wireless station (STA) operable to communicate with a first access point (AP) and roam to a next access point (AP), wherein said next AP pre-caches a number of IP addresses from a backend Dynamic Host Configuration Protocol (DHCP) server; and wherein said wireless station (STA) gathers IP layer address and sub-network information from said next Access Point (AP) during roaming.07-23-2009
20090327694Methods and apparatus for providing integrity protection for management and control traffic of wireless communication networks - Embodiments of the present invention provide a method comprising transmitting, by a communication node, an information element (IE), the IE including a feature field indicating whether the communication node operates in accordance with an integrity protection protocol specifically for management frames, and the IE further including an enforcement field that advertises whether the integrity protection protocol for management and control frames is mandatory, and generating, by the communication node, a pairwise transient key (PTK), the PTK including a first plurality of keys and a pairwise integrity key (PIK), wherein the first plurality of keys are configured to protect an integrity of data frames transmitted by the communication node and the PIK is configured to protect an integrity of management frames transmitted by the communication node, wherein management frames are dedicated to management traffic and wherein the first plurality of keys and the PIK are different keys. Other embodiments may be described and claimed.12-31-2009
20100027440Diagnostic information on multicast communications - Various embodiments of the invention pertain to a wireless communications device to receive multicast transmissions, and to transmit diagnostic information regarding those multicast communications in response to a triggering event. Other embodiments pertain to another wireless communications device to transmit the multicast transmissions, request the diagnostic information, and receive that information.02-04-2010
20100081447DYNAMIC CHANNEL ALLOCATION - Embodiments of methods and apparatus for dynamic channel allocation are disclosed. In various embodiments, an access point (AP) of an infrastructure based wireless network may allocate one or more wireless channels to wireless devices of a non-infrastructure based wireless network. The allocated channels may be selected to reduce a likelihood of communications among the devices of the non-infrastructure based wireless network interfering with communications among the devices of the infrastructure based wireless network. Additional variants and embodiments may also be disclosed and claimed.04-01-2010
20100093343METHODS AND APPARATUS FOR PROVIDING A ROAMING SUPPORT SYSTEM - Embodiments of methods and apparatus for providing a roaming support system are generally described herein. Other embodiments may be described and claimed.04-15-2010
20100142489METHODS AND APPARATUS FOR PROVIDING A HANDOVER CONTROL SYSTEM ASSOCIATED WITH A WIRELESS COMMUNICATION NETWORK - Embodiments of methods and apparatus for providing a handover control system associated with a wireless communication network are generally described herein. Other embodiments may be described and claimed.06-10-2010
20100271959Discovery channel and discovery beacon for peer-to-peer devices in wireless communications network - In a multi-channel wireless communications environment, at least one of the channels may be used for the purpose of allowing devices to discover each other so that they may subsequently communicate with each other on another channel. In some embodiments a special discovery beacon may be used on that channel, which is dedicated to the purpose of allowing the devices to discover each other.10-28-2010
20100332662Peer-to-peer negotiation in a wireless network - When two wireless communication devices discover each other and prepare to associate with each other, they perform a negotiation with each other to decide which will act as the network controller in that association. The negotiation may include an exchange of information indicating which device is more suitable to act as a network controller.12-30-2010
20110085462METHODS AND APPARATUS FOR PROVIDING INFORMATION INDICATIVE OF TRAFFIC DELAY OF A WIRELESS LINK - Embodiments of methods and apparatus for providing information indicative of traffic delay of a wireless link are generally described herein. Other embodiments may be described and claimed.04-14-2011
20110150223WIRELESS DEVICE AND METHOD FOR REKEYING WITH REDUCED PACKET LOSS FOR HIGH-THROUGHPUT WIRELESS COMMUNICATIONS - Embodiments of a wireless device and methods for rekeying with reduced packet loss in a wireless network are generally described herein. In some embodiments, during rekeying operations a new key for reception may be installed early (i.e., prior to receipt of a rekeying confirmation message). The use of the new key for transmission may be delayed until after receipt of the rekeying confirmation message. The early installation of the new key for reception may allow both the new key and old key to be active at the same time for use decrypting received packets to reduce packet loss during rekeying operations. The rekeying confirmation message may be the fourth message of a four-way handshake for rekeying. In some embodiments, two key identifiers may be alternated between four-way handshakes to prevent deletion of the old key.06-23-2011
20110154038Multi-band/multi-link secure key generation and delivery protocol - A method is described for negotiating the use of multi-link ciphering and for the generation of unique keys for each of the links using a single 4-way handshake protocol exchange.06-23-2011
20110161697METHOD AND SYSTEM FOR DISCOVERABILITY OF POWER SAVING P2P DEVICES - In a method and system, a first wireless device may be periodically cycled between an available state and a power saving state. While in the available state, the first wireless device may receive a probe request sent from a second wireless device operating in a discovery state. The first wireless device may transmit a probe response to the second wireless device. Other embodiments are described and claimed.06-30-2011
