Abstract: An apparatus receives a message including results of measurements on signals of a WLAN access point. The apparatus determines as a first condition whether the message comprises no indication of a position obtained in a non-cell based positioning and/or no information enabling a non-cell based positioning. The apparatus determines as a second condition whether the message comprises in addition results of measurements on signals of at least one cell of a cellular communications network. If the conditions are met, the apparatus determines a position based on the results of measurements on signals of the at least one cell of a cellular communications network and causes storage of location information that is based on the determined position in a memory for the WLAN access point, in case no location information has previously been stored in the memory for the WLAN access point.

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: An apparatus receives coordinates of a location and selects an object of a first layer of a tree structure based on the coordinates. The apparatus determines whether data assigned to the selected object comprises an identifier of an area or a pointer to a set of objects of a respective next layer of the tree structure. If the data comprises a pointer to a set of objects, the apparatus selects one of the objects from the set of objects based on the received coordinates and continues with determining whether data assigned to the selected object comprises an identifier or a pointer. If the data comprises an identifier of an area, the apparatus reads the data comprising the identifier and provides the identifier as a result of a mapping of a location to an identifier of an area. A computer readable storage medium stores a database having a corresponding tree structure.

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

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: For supporting the use of positioning assistance data, the positioning assistance data is broadcast in a plurality of different logical sub-channels. The positioning assistance data is distributed to the plurality of different logical sub-channels depending on its content.

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.

Abstract: Systems and methods provide a network's synchronization status to a terminal when the terminal receives a transmission from the network. This network synchronization status can be indicated in accordance with various methods including, but not limited to the following: with a status flag in a network message; in a network capability indication; in a network's positioning capability indication; cell/network time relation information; in a time relation information of different Radio Access Technologies; and implicitly with another parameter and/or by a request for a certain measurement. When the network's synchronization status is determined, accurate time information/time assistance data can be maintained at the terminal.

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.
