摘要:
A mobile station (106) establishes a real time communication link via an access point (102) for carrying voice or other time-sensitive data. A WLAN subsystem (204) of the mobile station is normally kept in a low power state. Upon initiating a communication link the mobile station signals to the access point that uplink poll-based power save delivery mode will be used (614), and the access point reserves resources to assure the necessary quality of service. The mobile station initiates a frame transaction by first powering up the WLAN subsystem (712), acquiring the WLAN channel (407), and transmitting a polling frame. Upon successful receipt of the polling frame the access point prepares to reply with a response frame at an unspecified time within service window, during which time the mobile station maintains the WLAN subsystem power up and ready to receive the response frame. Upon successful receipt of the response frame, the mobile station places the WLAN subsystem back into a low power state.

A method (400, 500, 800), and apparatus (212, 230, 240) provide for mobility in WLAN voice systems. In one embodiment a processor (651) coupled to a memory (652) and a radio resource (653) determines from that client (150) should move, based for example on a signal parameter, to an adjacent MSN (240). Adjacent MSNs are discovered and a modification of a portion of a tunnel switched path to the adjacent MSN is made and a portion released after the modified path is established. Information is transferred to client 150 over the tunnel using a lower layer address such as a MAC address.

The present invention provides a method, system, and computer program for providing synchronous execution between objects written in an object-oriented programming language and business logic written in a procedural programming language, while executing under control of an interactive test facility for debugging purposes. A single, logical interface is provided during debugging, while actually spanning multiple programming models based on different technologies. Using the present invention, the developer is able to debug both the object-oriented user interface part and the procedural business logic part of an application as the code executes in an integrated manner.

A method for preventing co-channel operation with a radar system includes the steps of setting a state of a first communication channel to active, connecting to a first wireless access point on the first communication channel, passively scanning at least a second communication channel for communication from a second wireless access point, setting a state of the second channel to active if frames are received on the second channel, determining whether an elapsed time since frames were received on at least one of the first channel and the second channel has exceed a predefined value, and in response to the predefined value being exceeded for at least one of the first channel and the second channel, setting the state of a corresponding one of the first channel and the second channel to passive.

A soft plastic articulating fishing lure includes a head and a plurality of body sections integrally molded with hinge sections. The hinge sections are preferably smaller in height than the respective body sections they join to promote increased swimming action at lower pull speed. Central body sections are preferably molded with relatively rounded back and relatively flatter front to promote water flow to effect swim-like movement of the lure. When fished, the lure articulates at the hinge joints only. In one embodiment, the head portion includes a molded slot, and a weighted insert is provided therein defining eyes for fishing line and hook, and a weights for lure control. In another embodiment, an insert with hook is provided within a slot in the head of the head and the hook is caused to rotate upwards out of the recess and into the mouth of the fish to hook the fish.

A disc brake assembly for a vehicle having a caliper mounted to a non-rotating structure of the vehicle and a housing mounted to a rotating structure of the vehicle fixedly connected to a rotor within the housing. A pressure plate and a pair of annular brake discs on each side of the rotor and extending parallel to the rotor are disposed within the housing and mounted to the caliper for axial movement into the pressure plate. At least one annular brake disc is axially moveable by a hydraulically or pneumatically urged annular piston disposed in caliper.

Methods and apparatus for filtering wagering game content are described herein. In one embodiment, the wagering game system includes a wagering game content filter to receive wagering game content over a communications network and to authenticate the wagering game content. The wagering game system can also include a memory unit to receive the wagering game content after the wagering game content filter has authenticated the wagering game content. The wagering game system can also include a processor to fetch the wagering game content from the memory unit and to conduct a wagering game based on the wagering game content.
摘要:
An Access Point (AP) receives a first set of timing information comprising timing information for at least one neighboring AP and conveys, to a user equipment (UE), a second set of timing information comprising timing information for the at least one neighboring AP, wherein the second set of timing information is derived from the first set of timing information. Based on the second set of timing information, the UE is able to determine a time to scan the at least one neighboring AP. In various embodiments of the present invention, the AP may receive the first set of timing information from another UE or may receive the timing information without the involvement of the another UE, for example, via a network interconnecting the APs or by monitoring an air interface of the at least one neighboring AP.

A system and method switches between an active call and a call on hold when handing off a mobile station (204) from a Wireless Local Area Network (WLAN) (202). A Handover Starting message is received from a mobile station. The Handover Starting message includes at least one first identifier. A Notification message is also received. The Notification message includes a second identifier. The at least one first identifier is compared to the second identifier and a handover of the mobile station (204) proceeds when a match is determined. Subsequently, the mobile station (204) switches from an active call to a call on hold.
