It is inter alia disclosed to select a relative positioning method from a set of at least two different relative positioning methods that are for determining an estimate of a relative position between a first entity and a second entity. The relative positioning method is selected in dependence on at least one of the following criteria: an estimated/measured distance between the first entity and the second entity; 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 entity and the second entity, 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 entity and the second entity. |
