Abstract
A solution is provided for dynamic allocation of cell identifiers in a cellular mobile telecommunication system. Cell identifiers being reused in a cellular radio access network of the cellular mobile telecommunication system are managed by a cell identifier manager configured to handle dynamic allocation of the cell identifiers to a plurality of base stations. Upon detection of a new base station or reactivation of an existing base station in the radio access network, the cell identifier manager allocates a cell identifier to the base station in such a manner that two base stations having the same cell identifier do not interfere with one another, i.e. do not cause cell identification problems in the radio access network.
