The method is selected in dependence on at least one of the following criteria: an estimated/measured distance between the first and second entities; a relative positioning capability, of at least one of the first entity, the second entity and at least one server entity associated with at least one of the first and second entities, to determine an estimate of a relative position between two entities; and an availability, at at least one of the at least one server entity, of a service providing data of at least one reference entity useable for determining an estimate of a relative position between the reference entity and one of the first and second entities.

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: Systems and methods are provided allowing for a vendor-defined payload in a standardized user-plane location solution/protocol, where proprietary extension support is introduced into one or more standardized solutions. In accordance with a first embodiment, a location payload consists of structures for transferring requests, assistance data, measurements and positioning instructions. Therefore, a proprietary extension is included in each of these structures so that, for example, proprietary assistance data can be requested in an appropriate structure. In accordance with another embodiment, a proprietary extension is introduced at the highest abstraction level. For example and in an actual implementation, a vendor can define that in the beginning of the proprietary payload, the proprietary extension is defined, whether the proprietary payload contains a request, assistance, etc.

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 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.
