Abstract: A method for requesting and providing on-demand priority to internet protocol (IP) flows is disclosed. A request to invoke transmission priority is received. Whether to mark a priority invocation packet for an IP flow with a priority Differentiated Services Code Point (DSCP) marking is determined The priority invocation packet is marked based on the determination and sent. A priority invocation packet for an IP flow that has a priority DSCP marking is received from a wireless device. The priority invocation packet is sent to its destination. Transmission priority is provided to IP flows received from the wireless device or sent to the wireless device for a period of time or until an indication of failed authorization is received.

Abstract: A radio frequency receive chain of an access point is reused for different functions. For example, the same RF receive chain may be used to receive on a downlink at certain points in time and on an uplink at other points in time. An RF receive chain that is used to derive synchronization from downlink signals received from a macro system also may be used to receive uplink signals from an access terminal to provide assistance for hand-in of the access terminal. Accelerated searching for hand-in may be provided through the use of a relatively small search window for hand-in of an access terminal to a small coverage access point. In some aspects, the search window may be defined based on the distance between access points or calibration of synchronization error between access points.

Abstract: Methods and apparatus are presented herein for controlling the degree of precision with which geographic information is reported to a requesting entity. A precise geographic location is used to determine an adjusted geographic location, which is then transmitted to the requesting entity rather than the precise geographic location.

Abstract: Ambiguity (e.g., confusion) associated with access point identifiers may be resolved by querying candidate target access points and/or by using historical records indicative of one or more access points that the access point has previously accessed. For example, messages may be sent to access points that are assigned the same identifier to cause the access points to monitor for a signal from an access terminal that received the identifier from a target access point. The target access point may then be identified based on any responses that indicate that a signal was received from the access terminal. In some aspects the access points subject to being queried may be selected using a tiered priority. In addition, it may be determined based on prior handoffs of a given access terminal that when that access terminal reports a given identifier, the access terminal usually ends up being handed-off to a particular access point.

Abstract: An access point is configured based on signals received from one or more access points on a forward link. Such an access point may comprise, for example, a relatively small coverage area access point and/or an access point that is deployed in an ad-hoc manner. In some aspects, an access point may determine its location based on signals received from several neighboring macro access points. In some aspects, the timing of an access point may be synchronized to timing indicated by signals that are received from one or more neighboring access points.

Abstract: An access terminal defines a search window based on a distance between access points. Here, a first one of the access points may comprise a macro access point from which the access terminal acquires timing. The search window may be used to monitor for pilot signals from a second one of the access points. For example, the second access point may comprise a femto node that provides relatively small area coverage. In some aspects the definition of the search window may involve adjusting (e.g., advancing) a center of a search window based on the distance between the access points. In addition, the access terminal may employ a smaller search window when it is searching for pilot signals from a femto node as compared to when it is searching for pilot signals from a macro access point.

Abstract: Identification of an access point to which an access terminal is to be handed-off involves, in some aspects, identifying one access point of a set of access points that may have been detected by an access terminal. For example, an access terminal may receive a signal having an identified characteristic (e.g., a particular phase offset) from an access point. Each access point of a set of access points associated with the identified characteristic may be directed to attempt to decode a signal from the access terminal. The access point of the candidate set to use for the handoff operation may then be determined based on the signal received from the access terminal, if any, by each of the candidate access points.

Abstract: A system, a method and computer product for synchronizing of a femto cell with a macro cell, the method comprising: placing a forward link receiver into the femto cell; receiving by a micro cellular network the femto cell transmission timing; and synchronizing the femto cell transmission timing with the macro cellular network transmission timing in reliance on the forward link receiver signal. Further, a system, a method and computer product for allocating pilot phases to femto cells, the method comprising: creating at least as many new potential pilot phases for femto cells as there are for macro cells; and allowing a mobile device on a macro cell to search and find a femto cell pilot without explicitly listing femto pilot phases in the neighbor list.

Abstract: System and method are provided for redirecting a communication device between a macro network and a femtocell network using a service redirection message (SRDM). In an embodiment, the communication device registers with the network which then determines the subscription status of the communication device to a femtocell network. If the subscription is confirmed, using the SRDM the system redirects the communication device to a communication frequency used by the femtocell network. Upon receipt of the SRDM, the communication devices tunes to a communication frequency specified in the SRDM. The system may segregate the CDMA channels used by the macro network, one set containing channels exclusive to the macro network and the other containing channel or channels used by both the macro network and the femtocell network. In this way, the communication device is prevented from entering a frequency re-hashing loop.

Abstract: A method for managing access to a macro mobile operator core network (250) by a guest terminal device (225) through a femto cell (210), and more particularly through a femto cell (210) connected to the Internet (240). When a guest terminal seeks guest access to network services at a site for example while a guest at a person's home, or a customer in a shop, or a traveler in a transportation station, access may be granted by information exchange between the proprietor of the site and the macro mobile operator core network (250). Access may be granted via the proprietor via a terminal device (220) connected wirelessly to the core network, or by any device connected to the Internet. Once access is granted, the guest terminal device (225) receives sufficient information to initiate communication with femto cells (210) in the proximity of the site, and thereby begin using Internet-based communication.

Abstract: An apparatus and method for counting the number of cycles of a sensor signal and of a reference signal that occur during respective time intervals associated with a sampling interval defined by a sample signal. Sensor and reference gate signals are produced and respectively define sensor and reference intervals. The sensor interval begins and ends synchronously with respect to the sensor signal, and the reference interval begins and ends synchronously with respect to the reference signal. The sensor, reference and sampling intervals are approximately coextensive with one another. Cycles of the sensor and reference signals are counted during the sensor and reference intervals, respectively. The process may be repeated for a plurality of successive sampling intervals.

Abstract: An accelerometer has two proof masses each constrained from movement by a beam resonant force transducer. The proof mass-force transducer systems are mounted with the sensitive axes of the proof masses aligned and the force transducers arranged so that their resonant frequencies f.sub.1 and f.sub.2 vary oppositely with a change in acceleration. The acceleration is determined in accordance with the relationa=A.sub.1 f.sub.1 -A.sub.2 f.sub.3 +A.sub.0ora=A.sub.1 f.sub.1.sup.2 -A.sub.2 f.sub.2.sup.2 +A.sub.0where a is the acceleration and A.sub.1, A.sub.2 and A.sub.0 are calibration coefficients.
