It is further disclosed an according apparatus, computer program and system. ## Claims ### Claim 1 A method, comprising: obtaining one or more first fallback objects indicative of a geographic area that is covered by one or more cells of a communication network, wherein a respective first fallback object comprises at least one cell and/or an area information indicative of the geographic area the respective at least one cell belongs to; obtaining one or more pieces of cell information of a number of positioning requests that a respective cell of the one or more cells has received; determining one or more second fallback objects out of the one or more first fallback objects, wherein the one or more second fallback objects are determined based at least partially on whether or not a needed level of accuracy for determining a position is achievable based on the respective second fallback object; determining for an area of the respective second fallback object in that the needed level of accuracy for determining a position is not achievable, one or more cells based at least partially on the one or more pieces of cell information; and outputting the determined one or more second fallback objects and/or the determined one or more cells for usage in a generation of a radio map. ### Claim 2 (depends on 1) The method according to claim 1, wherein the one or more second fallback objects are determined based, at least in part, on a comparison of the size of the respective second fallback object with a pre-determined or determined according to pre-defined rules threshold value. ### Claim 3 (depends on 1) The method according to claim 1, wherein the one or more pieces of cell information are further indicative of a usage of a certain cell of the one or more cells of the communication network. ### Claim 4 (depends on 2) The method according to claim 2, further comprising: determining one or more cells to replace at least one of the one or more second fallback objects in case the size of the at least one second fallback object is above the threshold value. ### Claim 5 (depends on 1) The method according to claim 1 further comprising: generating a radio map based, at least in part, on the one or more second fallback objects and/or the one or more cells enabling a position to be determined based at least partially on the generated radio map. ### Claim 6 (depends on 5) The method according to claim 5, wherein at least one reference position that can be used by an electronic device to determine its current location is comprised by or a part of the respective first and/or second fallback object. ### Claim 7 (depends on 1) The method according to claim 1, further comprising: determining one or more parameters based, at least in part, on the determined or output one or more second fallback objects and/or the determined or output one or more cells, wherein the one or more parameters are indicative of a performance level indicator representing an achievable positioning accuracy. ### Claim 8 (depends on 7) The method according to claim 7, further comprising: verifying the one or more parameters based on a comparison with one or more pre-determined or determined according to pre-defined rules reference parameters; and repeating the step of determining of the one or more second fallback objects and/or cells until the verifying leads to an acceptable result. ### Claim 9 (depends on 1) The method according to claim 1, wherein a respective fallback object of the one or more first fallback objects is associated with at least one reference position within the geographic area, wherein dependent upon the position of the reference position within the geographic area, a certain level of positioning accuracy is achievable. ### Claim 10 (depends on 9) The method according to claim 9, wherein the determining of the one or more second fallback objects is further based on the certain level of accuracy. ### Claim 11 An apparatus comprising at least one processor and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to: obtain one or more first fallback objects indicative of a geographic area that is covered by one or more cells of a communication network, wherein a respective first fallback object comprises at least one cell and/or an area information indicative of the geographic area the respective at least one cell belongs to; obtain one or more pieces of cell information indicative of a number of positioning requests that a respective cell of the one or more cells has received; determine one or more second fallback objects out of the one or more first fallback objects, wherein the one or more second fallback objects are determined based at least partially on whether or not a needed level of accuracy for determining a position is achievable based on the respective second fallback object; determine for an area of the respective second fallback object in that the needed level of accuracy for determining a position is not achievable, one or more cells based at least partially on the one or more pieces of cell information; and output the determined one or more second fallback objects and/or the determined one or more cells for usage in a generation of a radio map. ### Claim 12 (depends on 11) The apparatus according to claim 11, wherein the one or more second fallback objects are determined based, at least in part, on a comparison of the size of the respective second fallback object with a pre-determined or determined according to pre-defined rules threshold value. ### Claim 13 (depends on 12) The apparatus according to claim 12, wherein the at least one memory and the computer program code are further configured to, with the at least one processor, cause the apparatus to determine one or more cells to replace at least one of the one or more second fallback objects in case the size of the at least one second fallback object is above the threshold value. ### Claim 14 (depends on 11) The apparatus according to claim 11, wherein the one or more pieces of cell information are further indicative of a usage of a certain cell of the one or more cells of the communication network. ### Claim 15 (depends on 11) The apparatus according to claim 11, wherein the at least one memory and the computer program code are further configured to, with the at least one processor, cause the apparatus to generate a radio map based, at least in part, on the one or more second fallback objects and/or the one or more cells enabling a position to be determined based at least partially on the generated radio map. ### Claim 16 (depends on 11) The apparatus according to claim 11, wherein the at least one memory and the computer program code are further configured to, with the at least one processor, cause the apparatus to determine one or more parameters based, at least in part, on the determined or output one or more second fallback objects and/or the determined or output one or more cells, and wherein the one or more parameters are indicative of a performance level indicator representing an achievable positioning accuracy.
