Directed retry for call setup

A method for directed retry in a mobile communication system, the said method comprising:

• measuring the reception level of signals from neighboring cells of a target cell in a mobile station;
• sending the measurement results as a report message from the mobile station MS to a mobile communication network;
• detecting a need for directed retry;
• selecting at least one neighboring cell as the candidate cell for directed retry on the basis of the measurements;
• and
• executing the directed retry into the selected target cell;
• wherein the method further comprises:
• determining a change in the reception level of the signal of at least one candidate cell on the basis of measurements performed in the mobile station;
• determining an interference level of the signal of at least one candidate cell on the basis of measurements performed in the mobile station;
• and
• selecting the target cell for directed retry from the candidate cells by using the determined changes in the reception levels and determined interference levels of the signals so that the target cell selected is the candidate cell whose determined change in reception level and ratio of the reception level to the determined interference level is maximized.
