Abstract: An apparatus, a method and a computer program, the apparatus comprising: collection circuitry configured to collect position reference data, wherein the collected position reference data is for assisting another apparatus to determine a position of the another apparatus based upon wireless signals received by the another apparatus; receiver circuitry configured to receive control data relating to controlling the transmission of collected position reference data by the apparatus; transmitter circuitry configured to transmit collected position reference data; and processing circuitry configured, in dependence upon the received control data, to selectively control transmission of collected position reference data by the transmitter circuitry.

Abstract: It is disclosed a method, an apparatus and a computer program for monitoring, for a position of a set of one or more positions that are associated with a coverage area of a communication node, if a report comprising a position associated with said coverage area of said communication node and lying in a defined environment of said position for which said monitoring is performed is received as a validation of said position for which said monitoring is performed.

Abstract: It is disclosed an apparatus, a method and a computer program for determining, at a terminal, whether at least one terminal position associated with a coverage area of a communication node shall be discarded or reported to allow at least one of said coverage area and said communication node to be characterized at least partially based on said at least one reported terminal position.

Abstract: It is disclosed to determine whether information useable for a generating/updating process that comprises generating and/or updating at least one model for a coverage area of a communication node shall be discarded or made available to said generating/updating process.

Abstract: It is disclosed to operate a generating/updating process that comprises generating and/or updating at least one model for a coverage area of a communication node and/or at least one process associated with said generating/updating process in dependence on at least one state of a state machine.

Abstract: An apparatus, method and computer program, the apparatus, comprising: receiver circuitry configured to receive first position reference data from a remote location, the first position reference data relating to a first geographical area and being for assisting the apparatus to determine a position of the apparatus within the first geographical area, using wireless signals received at the apparatus; collection circuitry configured to collect second position reference data, the second position reference data being for modification of the first position reference data, at a remote location; positioning circuitry configured to determine a position of the apparatus, the position being within the first geographical area; transmitter circuitry configured to transmit collected second position reference data; and processing circuitry configured, in dependence upon the determined position of the apparatus and the first position reference data, to selectively control transmission of collected second position reference d

Abstract: Methods and devices may request and provide assistance data from an assistance server to a receiver in a global navigation satellite system. A request for assistance data may include a preference list of navigation models suitable for the requesting receiver. Multiple preference lists for different navigation model types (e.g., orbit model, clock model, almanac model) may be included in a single list and/or data structure, or as multiple lists and/or data structures. An assistance server may receive and process the preference list, for example, by parsing and traversing the ordered list(s) for different navigation model types, in order to provide satellite navigation data to the receiver in accordance with suitable navigation models that are available at both the receiver and the assistance server.
