Abstract
A method and apparatus for implementing call forwarding in a mobile communication system comprising one or more closed user groups. The method comprises detecting conditional or unconditional call forwarding to a call forwarding number in connection with call set-up, checking whether set call forwarding is directed to the voice mail, and carrying out call forwarding in response to the fact that call forwarding is directed to the voice mail, regardless of a possible bar to call forwarding due to interaction between the call forwarding facility and the closed user group. The method and system of the invention allow to eliminate the possible problems caused by the restrictions of the closed user group in connection with call forwarding to the voice mail.
