<p>The invention discloses a method for performing synchronisation of a mobile network device to a network control device of a present radio network region. The method comprises the steps of detecting (S1) a source radio network region from which a handover of said mobile network device to said present radio network region has been performed, determining (S2, S3) a start propagation delay value based on said detected source radio network region of said mobile station, and searching (S4) an actual propagation delay value by using a search strategy based on said determined start propagation delay value. Furthermore, also a network control device adapted to perform this method is disclosed. By this method the correct propagation delay can be detected very fast, since the values of the propagation delay from known neighbouring cells are stored and used to generate a start value for the search of the correct propagation delay.</p> |
