Abstract: In accordance with an example embodiment of the present invention, an apparatus comprises a receiver for receiving a list of access points detected at a location, a processor for determining the number of times at least one access point in the list is detected during a first period of time and a processor for determining to use an access point in generating a partial radio map based at least in part on the number of times the access point is detected during a second period of time.

Abstract: A method performed by an apparatus, the method comprising obtaining an identifier associated with an entity of a communication system, generating, from said identifier, a shortened derivative of said identifier, and using said shortened derivative of said identifier to retrieve a set of positioning information associated with said entity of said communication system. Also disclosed is a method performed by an apparatus, the method comprising obtaining an identifier associated with an entity of a communication system, obtaining a set of positioning information associated with said identifier, generating, from said identifier, a shortened derivative of said identifier, and associating said shortened derivative with said set of positioning information.

Abstract: An apparatus receives (111) information about at least two wireless access points obtained in a scan at a single location and retrieves (112) information from a record that is stored for a particular one of the at least two wireless access points. The apparatus determines (113) whether to update information about neighboring wireless access points in the record stored for the particular wireless access point by comparing received information with retrieved information. In case (114) it is determined to update information about neighboring wireless access points, the apparatus causes an update of information about neighboring wireless access points in the record stored for the particular access point based on the received information.

Abstract: An apparatus obtains information for radio channel modeling by checking at least one measurement based value of at least one set of measurement based values of a plurality of sets of measurement based values based on at least one timing measurement value, wherein each set of measurement based values originates from a respective mobile terminal in a communication network (111). The same or another apparatus may perform a radio channel modeling based on the obtained information (112).

Abstract: In accordance with an example embodiment of the present invention, a method performed by an apparatus comprises, causing said apparatus at least to perform one of providing and obtaining information on a serving cell that is, at a point of time, serving a mobile terminal and information related to a neighbor cell that is, at least substantially at said point of time, observed by said mobile terminal, wherein said serving cell is a cell of a first communication network, wherein said neighbor cell is a cell of a second communication network, and wherein said first communication network has a type that is different from a type of said second communication network and/or is operated by an operator that is different from an operator of said second communication network.

Abstract: 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.
