20090319605 | MOTION STATE INDICATOR FOR LOCATION-BASED SERVICES - A system and method by which an estimate can be provided to a location-based service provider concerning the motion state of a user of a terminal. Motion state information may be used to trigger a particular location-based service at a more desirable moment. The motion state information may also be used to help define the format of information sent to the user's terminal, as well as to define the content of the information that is to be sent to the user terminal. This enables an improved level of control of the distribution of location-based services, as information can be sent at a more optimal time and more relevant information can be sent to the user. | 12-24-2009 |
20100029218 | Apparatus, methods and computer programs - A method including: processing at a first processing frequency, such that each instance of processing is separated by a first processing time period, at least a first signal; increasing the processing frequency to a second processing frequency and switching from processing the first signal to processing a second signal; determining a parameter indicative of the quality of the second signal; and determining, within the first processing time period measured from the last instance of processing the first signal at the first frequency, which one or more signals to process at the next instance of processing by comparing respective parameters of at least the first and second signals. | 02-04-2010 |
20110175773 | MANAGING THE MEASUREMENT OF SIGNALS - For managing measurements on signals, a quality of received signals, for which a measurement circuit provides measurement results, is monitored. In the case that the quality does not exceed a set quality before Receive and monitor signal measurements an end of a reporting period, a reporting of measurement results that are available at the end of the reporting period is caused. In the case that the quality exceeds the set quality at a measurement instant before the end of the reporting period, the measurement circuit is put to a sleep mode and a reporting of extrapolated measurement results is caused, the extrapolated measurement results being measurement results from a measurement instant before the measurement circuit was put to a sleep mode extrapolated to the end of the reporting period. | 07-21-2011 |
20120276886 | Method and Apparatus for Acquiring Information Related to a Position - In accordance with an example embodiment of the present invention, a method and an apparatus are shown comprising receiving status information of an apparatus, and determining a probability for an update of information related to a position being obtained based on the status information. Based on the determined probability and an elapsed time since a last update of the information related to a position, it is determined whether to activate a receiver in order to obtain the update of information related to a position. | 11-01-2012 |
20120315896 | ACCURATE GNSS TIME HANDLING IN DUAL/MULTI-SIM TERMINALS - Method, apparatus, and computer program product example embodiments are disclosed for improving the speed and sensitivity of position determination by wireless communication devices using assisted Global Navigation Satellite Systems (A-GNSS).

20130088384 | Portable Communication Terminals and Methods for Cooperative Positioning Support During Poor Satellite Coverage - In one or more embodiments described herein, there is provided an apparatus including a memory having computer code stored thereon, and a processor. The code is configured to cause the apparatus to: receive partial GNSS data from one or more GNSS satellites relating to the geographical location of a first portable electronic device, wherein the received partial GNSS data is insufficient for determining the geographical location of the first portable electronic device; communicate with one or more further portable electronic devices in proximity to the first portable electronic device to access partial GNSS data relating to the geographical location of the respective further portable electronic devices; and use the accessed partial GNSS data of the further portable electronic devices to supplement the received partial GNSS data of the first portable electronic device to thereby determine the geographical location of the first device. | 04-11-2013 |
20130281111 | METHOD, APPARATUS, AND COMPUTER PROGRAM PRODUCT FOR DISTRIBUTED INDOOR THREE-DIMENSIONAL RADIOMAP - Method, apparatus, and computer program product example embodiments provide wireless position determination. According to an example embodiment, a method comprises generating in a mobile wireless device, grid nodes representing one or more floor areas in an enclosed space, based on a map of the enclosed space; estimating locations along a path of motion of a user of the mobile wireless device traversing the one or more floor areas, based on motion observations made by a motion sensor in the mobile wireless device and map information; generating a radiomap of the one or more floor areas by making radio measurements with the mobile wireless device, at the estimated locations along the path of motion, mapping the measurements to the generated grid nodes that are closest to the estimated locations; and compiling a fingerprint data structure of the radiomap, including observation elements representing the radio measurements at the mapped grid nodes. | 10-24-2013 |
20140243012 | SUPPORTING COVERAGE AREA MODELING - A system obtains information on positions stored for a communication node and criteria that are met by the node. The system selects a-priori information on a coverage area size that is stored for nodes meeting the criteria. Different a-priori information is stored for nodes meeting different criteria. The system estimates a value of at least one parameter representing a coverage area of the node based on the information on the positions and the selected a-priori information. The value of the at least one parameter is stored. For generating the a-priori information, the system may extract from a memory information indicating a size of a coverage area for each of a plurality of communication nodes, compute a statistical value based on information indicating a size of a coverage area that is extracted for a plurality of nodes meeting the same criteria, and provide the computed statistical value as a-priori information. | 08-28-2014 |
