Abstract: A method, apparatus, and signal-bearing media for determining a presence rule for a mobile device and updating presence information for the mobile device when the presence rule is met. The presence rule may have a condition and a corresponding state. When the condition is met, the corresponding state is saved in the presence information. The presence information may also contain reachability information for the mobile device.

Abstract: A mobile device includes network interfaces for communicating wirelessly with two different networks. The mobile device may operate as a gateway between the two networks by switching between the two network interfaces in order to pass information from one network intended for the other network.

Abstract: Techniques and structures are disclosed for allowing context-based searches to be performed from a wireless device. In at least one embodiment, a wireless device may append context-specific information, collected by at least one local sensor to a network search query to be delivered to a remote search engine when a network search is being performed. The wireless device may then receive search results from the remote search engine in response to the network search query that identify the elements of appended context-specific information that were used to perform the network search. The wireless device may then display these search results to a user.

Abstract: A master controller for managing items tagged with radio-frequency identification (RFID) tags includes a transceiver to transmit interrogation signals to the RFID tags and to receive response signals from the RFID tags. The master controller may also include a processor to determine the proximity of tagged items based on signal levels of the response signals, and to notify a user when certain ones of the tagged items are in a predetermined relation to a proximity threshold.

Abstract: According to an embodiment of the invention, the location of a mobile device and a direction in which the mobile device is moving are determined. Communications service changes for the mobile device are anticipated based at least in part on the location of the mobile device and direction in which the mobile device is moving.

Abstract: Apparatus, systems, and methods may provide operating system-independent geolocation information. A compact software and/or firmwave environment may be established prior to loading and/or initializing the main operating system. This environment, sometimes known as a pre-boot environment, may determine geolocation information and/or may provide user access to configuration information and methods, even when the operating system is absent or unavailable.

Abstract: A method is described for adaptive load-balancing and graceful termination of access points in a network having a plurality of access points. The method includes determining a need to reduce a load of a first access point, and increasing a beacon interval corresponding to the first access point in order to detract clients. Correspondingly, beacon intervals for other access points may be reduced in order to attract more clients.

Abstract: According to the invention, the provision of information regarding transaction assistance availability in a transaction environment is disclosed. According to an embodiment, a method comprises determining the location of a mobile device; determining the availability of transaction assistance; and transmitting information regarding availability of transaction assistance to the mobile device.

Abstract: According to an embodiment of the invention, the location of a mobile device and a direction in which the mobile device is moving are determined. Communications service changes for the mobile device are anticipated based at least in part on the location of the mobile device and direction in which the mobile device is moving.

Abstract: According to an embodiment of the invention, the location of a mobile client device is determined, the location being in a region. One or more potential communication partners for the mobile client device are identified for the region, the identification being based at least in part on the location of the mobile client device in the region. Contact information is provided to the mobile client device regarding the potential communication partners for the region.

Abstract: In one aspect of the invention is a method to notify users of wireless devices that tasks in their task list can be satisfied based on the user's location. A user enters a plurality of tasks in a wireless device. As the user travels with the wireless device, the user may pass providers that can satisfy tasks on the user's task list. If the user does, then the user is notified of such information.

Abstract: An intelligent, non-intrusive, adaptive wireless discount coupon delivery system over General Packet Radio Service (“GPRS”) bearer service. The system generates and delivers electronic coupons to subscribers' GPRS mobile stations from business entities in the subscribers' vicinity. The system bases its delivery on the subscribers' profiles stored in their mobile phones, which may include their cellular location and their shopping histories. The main components of the system include: a GPRS mobile station, a base station, a mobile-switching center (“MSC”), a serving GPRS service node (“SGSN”), a coupon generating server (“CGS”), an offer generating server (“OGS”), and store pricing databases. The system increases the facility and trustworthiness of wireless coupon delivery by isolating subscriber profile information from stores' pricing databases.

Abstract: A measurement receiver demodulator has a first processing channel for producing a filtered signal sample output where the signal samples are processed through a transmission system receiver filter and a second processing channel producing an unfiltered signal sample output where the signal samples are not processed through the transmission system receiver filter. The first processing channel down converts digitally modulated IF signal samples and filters the down converted signal samples using a combined transmission system receiver filter and front end hardware compensation filter. A synchronizer produces timing phase and rate offset parameters that are applied to a resampling filter to synchronize the filtered signal samples to symbol instances of the symbol modulation. The filtered, time-aligned signal samples are scaled using a derived scaling factor. A pilot offset level, if present, is estimated and removed.

Abstract: A method is described for maintaining a seamless communication session while switching devices. A user requests a communication session with a colleague device. The request for a communication session triggers a communication server to establish a first connection with the first device, and a second connection with the colleague device. When the user requests a switch from the first communication device to a second communication device, the request triggers the communication server to verify that the user of the second communication device is the same as the user of the first communication device. If the users are the same, then the communication server establishes a third connection with the second communication device, and then terminates the first connection with the first communication device. The second connection between the communication server and the colleague device is maintained such that entire process is transparent to the colleague.

Abstract: Briefly, in accordance with an embodiment of the claimed subject matter, a method and an apparatus to distribute data is provided, wherein the method includes examining the payload portion of the electronic data to determine whether and where to transmit the electronic data.
