Abstract: Examples disclosed herein relate to methods and apparatuses for observing signals transmitted by one or more transmitters in an asynchronous communication network and applying a time reference to generate a clock model. In one embodiment parameters representing the clock model may then be forwarded to other mobile devices to assist in positioning operations.

Abstract: Methods and apparatuses are provided for use with mode switchable navigation radios and the like. The methods and apparatuses may be implemented to selectively switch between certain operating modes based, at least in part, a mode-switch-ing test that takes into consideration one or more non-timed test conditions to determine if mode-switching may be enabled.

Abstract: Techniques for supporting location services in a user plane location architecture such as Secure User Plane Location (SUPL) are described. In an aspect, a terminal informs a location server of service capabilities of the terminal. The location server uses the service capabilities to request only location services supported by the terminal and to avoid requesting unsupported location services. The terminal generates a message containing its service capabilities and sends the message via a user plane, e.g., SUPL. The location server receives the message, obtains the service capabilities of the terminal, and stores these service capabilities for future network-initiated location sessions with the terminal. The location server determines whether a location service is supported by the terminal based on the service capabilities of the terminal. The location server communicates with the terminal via the user plane for the location service if supported by the terminal.

Abstract: In a radio frequency (RF) receiver, a receiver RF chain is tuned to a first (e.g., global positioning system (GPS)) channel to permit receipt of a first (e.g., GPS) signal over the first (e.g., GPS) channel on the receiver RF chain during a first time duration. The receiver RF chain is tuned to a second (e.g., cellular page) channel to permit receipt of a second (e.g., cellular page) signal over the second (e.g., cellular page) channel on the receiver RF chain during a second time duration, following the first time duration. The first (e.g., GPS) signal is processed during the first time duration and the second time duration, without any apparent interruption of the first (e.g., GPS) signal during the second time duration. The processing, for example, treats the actual interrup-tion as a temporary, short term fade of the first (e.g., GPS) signal during the second time duration, or provides a bridge signal (e.g., an estimated GPS signal on the receiver RF chain or an actual GPS signal received on another receiver RF chain) during the second time duration.

Abstract: Systems, apparatuses, and/or methods for resolving ambiguities associated with signals received from space vehicles (SVs) in a satellite navigation system. For example, certain methods include receiving a first SV signal from a first satellite positioning system (SPS), and reducing a bit edge ambiguity of a data signal modulating a second SV signal received from a second SPS based, at least in part, on information in the received first SV signal.

Abstract: Un procedimiento (800) de soporte a servicios de ubicación, que comprende: recibir (812) un mensaje enviado por un terminal (120) a un servidor de ubicación (130) a través de un plano de usuario, indicando el mensaje capacidades de servicio del terminal, comprendiendo las capacidades de servicio una indicación de al menos un servicio de ubicación activado que es soportado por el terminal, teniendo dicho servicio de ubicación activado un criterio de activación asociado para determinar si se obtiene una estimación de ubicación del terminal y para suministrar la estimación de ubicación a un cliente de ubicación (140); determinar (818) en el servidor de ubicación (130) si un servicio de ubicación es soportado por el terminal en base, al menos en parte, a las capacidades de servicio del terminal, en el que el servicio de ubicación es capaz de obtener la estimación de ubicación del terminal, al menos parcialmente, en respuesta a una ocurrencia de los criterios de activación; y comunicarse (820) con el terminal a través del plano de usuario para el servicio de ubicación, al menos parcialmente, en respuesta a la determinación de que el servicio de ubicación está soportado por el terminal, en el que dicha comunicación comprende transmitir parámetros de activación para dicho servicio de ubicación al terminal.

Abstract: A mobile Communications device uses a method for determining position that involves a positioning filter, such as a Kalman filter, which is initialized with measurements from reference stations such as satellite vehicles and/or base stations which may be acquired during different epochs. Accordingly, the positioning filter may be used for position estimation without the need to first acquire at least three different signals during the same measurement epoch.
