Abstract: For supporting a relative positioning, information on barometric pressure at a first device and information on barometric pressure at a second device is converted into a difference in altitude between the first device and the second device. The difference in altitude between the first device and the second device is then used in determining a position of the first device relative to the second device.

Abstract: An apparatus comprising: a processor and memory including computer program code, the memory and the computer program code configured to, with the processor, cause the apparatus to: detect sound from an environment proximal to a device; determine a context of the device using the detected sound; and provide signaling to allow for selection of a context-specific service for use in navigation by the device based upon the result of the determined context.

Abstract: A system for supporting electronic positioning in apparatuses. Apparatuses may receive various wireless signals over time (800). The strength of the received wireless signals may be determined by the apparatuses (802), and based on this determination an occurrence for each received wireless signal may be accumulated in a histogram in the apparatus (804). Information based on the histogram may then be transmitted to a mapping database (810). The mapping database may then utilize this information to, for example, create signal-based maps for use in apparatus positioning.

Abstract: Systems and methods are provided to allow for the use of existing satellite identification parameters generically, so as to allow for Global Navigation Satellite System (GLONASS) identification. In addition, an optional or conditional parameter is linked to the satellite identification parameter for a frequency identification, where frequency identification is indicative of a Frequency Division Multiple Access (FDMA) frequency value. Such a frequency identification parameter is optional as it is needed only for current GLONASS and/or near-future GLONASS (e.g., GLONASS-M) satellites. Hence, utilization of the frequency identification parameter maybe unnecessary and therefore, not included/not linked when considering next generation GLONASS satellites, e.g., GLONASS-K satellites. Additionally, signals supported by particular global positioning system (GPS) satellites can be indicated with the use of generic satellite identification.

Abstract: For enhancing the positioning of a mobile device, a server may generate parameters for each of a plurality of models of a coverage area of a transmission node on the assumption of a different spatial constraint for a location of a receiving device. The parameters of each of the models may be provided along with the associated indication of the spatial constraint for transmission. The position of a mobile device may be determined by evaluating the parameters of each of the models.

A further method for obtaining a service by a terminal related to an assistance server comprising sending by the terminal a capability request, and receiving, in the terminal, information indicative of capabilities related to the assistance server, wherein the information indicative of capabilities comprises indications of available assistance related to the assistance server.

Abstract: Session parameters and/or information regarding session parameters are provided to a target device from a location server in a periodic assistance session. For example, the location server starts an unsolicited periodic assistance session, and transmits information indicating the unsolicited assistance session is periodic as well as any relevant session parameters to the target device. The location server may change session parameters “on the fly,” and inform the target device of the modified session parameters. The target device may initiate a session and requests certain parameters, to which the location server responds with an indication as to what parameters the target device will actually receive. Additionally, the target device may modify the session parameters, and the location server can respond to the target indicating whether or not the modification was accepted or if the modification was accepted in a modified form.

Abstract: A system for enhancing the provision of location information based on previously stored visual data. Apparatuses may utilize sensors to sense at least visual information at a location. The sensed visual information may include attributes that may be defined as one or more visual elements in the recorded visual information. The one or more visual elements may then be stored in a mapping database in association with the location.

Abstract: A system for providing positioning functionality in an apparatus. Apparatuses may comprise various sensor resources and may utilize these resources to sense information at a location. For example, an apparatus may sense visual, signal and/or field information at a location. The apparatus may then compare the sensed information to a mapping database in order to determine position.

Abstract: A system for creating a representation of a location based on information sensed at the location. For example, apparatuses may comprise various sensors that sense apparatus-related information (e.g., motion, direction, etc.) while also visual, signal, field, etc. information pertaining to a location. Apparatuses may store sensed information about the apparatus while at a particular location, and about the particular location itself, in a mapping database, which may then associate the various types of sensed information with information already stored in the database in order to create a representation of the location.

Abstract: A first apparatus generates a request for positioning data, includes in the request an indication that an estimate of the amount of the requested positioning data is to be provided, and causes a transmission of the request. A second apparatus receives the request, generates a response including an estimate of the amount of the requested positioning data, and causes a transmission of the response. The first apparatus receives the response.

Abstract: A system for providing positioning functionality in an apparatus without having to implement dedicated hardware. An apparatus that desires to receive directional information may receive a message from another apparatus (e.g., access point or AP). The AP may operate in various modes that, for example, may provide directional information to other apparatuses as part of a general broadcast (e.g., a wireless local area network, or WLAN, beacon signal) or in response to messages requesting directional information that are received from other apparatuses. After receiving the message from the AP, the apparatus may determine if the message comprises directional information. If the message is determined to comprise directional information, directional information from the received message may be utilized to determine apparatus location. Otherwise, the apparatus may then send a message requesting directional information to the AP, which may prompt the AP to provide directional information.

Abstract: For enhancing the quality of a relative positioning, a filter is adjusted depending on information on a movement of a satellite signal receiver. A position of the satellite signal receiver is determined relative to a reference station using the filter, wherein measurements on satellite signals received by the satellite signal receiver and measurements on satellite signals provided for the reference station are used as input to the filter. The measurements for the reference station may be received in messages which are assembled and provided for transmission and which may include in addition an indication of a current movement of the reference station.
