1 - 27 . (canceled)

28 . A method comprising at an apparatus:

receiving a plurality of reports from at least one mobile terminal, which is connected to a particular cell of a cellular communication network, each report including an identification of a first type of a plurality of cells of the cellular communication network currently observed by the at least one mobile terminal and, associated with each identification of the first type, a result of at least one measurement on signals;

computing for each identification of the first type a sum of results of the at least one measurement in the plurality of reports; and

determining, based on the computed sums, one of the identifications of the first type to be an identification of the first type of the particular cell.

29 . The method according to claim 28 , wherein each report further includes an identification of a second type for the particular cell.

30 . The method according to claim 29 , wherein the identification of the first type is a local cell identity and wherein the identification of the second type is a global cell identity.

31 . The method according to claim 28 , wherein the particular cell is a serving cell.

32 . The method according to claim 28 , wherein the at least one measurement on signals is a signal strength measurement.

33 . The method according to claim 28 , wherein determining one of the identifications of the first type to be an identification of the first type of the particular cell comprises determining the identification of the first type which is associated with the highest sum to be the identification of the first type of the particular cell.

34 . The method according to claim 28 , wherein before determining one of the identifications of the first type to be the identification of the first type of the particular cell based on the computed sums, the sums are computed cumulatively at least until at least one of:

one of the computed sums exceeds a first threshold value; and

a ratio between a highest computed sum and a second highest computed sum exceeds a second threshold value.

35 . The method according to claim 28 , wherein the sums are reset at least one of:

periodically; and

after one of the computed sums has reached a threshold value.

36 . The method according claim 28 , wherein at least one of the reports comprises in addition an indication of a position of the at least one mobile terminal.

37 . The method according to claim 29 , wherein results of measurements associated in the received reports to the identification of the first type, which is determined to be the identification of the first type of the particular cell, are stored in a positioning database with association to the identification of the second type for the particular cell.

38 . 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 an apparatus at least to perform:

receive a plurality of reports from at least one mobile terminal, which is connected to a particular cell of a cellular communication network, each report including an identification of a first type of a plurality of cells of the cellular communication network currently observed by the at least one mobile terminal and, associated with each identification of the first type, a result of at least one measurement on signals;

compute for each identification of the first type a sum of results of the at least one measurement in the plurality of reports; and

determine, based on the computed sums, one of the identifications of the first type to be an identification of the first type of the particular cell.

39 . The apparatus according to claim 38 , wherein each report further includes an identification of a second type for the particular cell.

44 . The apparatus according to claim 38 , wherein the computer program code is configured to, with the at least one processor, cause an apparatus to compute the sums cumulatively at least until one of the computed sums exceeds a threshold value, before determining one of the identifications of the first type to be the identification of the first type of the particular cell based on the computed sums.

45 . The apparatus according to claim 38 , wherein the computer program code is configured to, with the at least one processor, cause an apparatus to compute the sums cumulatively at least until at least one of:

one of the computed sums exceeds a first threshold value; and
