Abstract
A method for reducing the number of unsuccessful service change attempts of a first mobile terminal is presented. The mobile terminal (1, 1a, 1b, 420) is connectable via a mobile network to a further terminal by establishing a call connection for providing a first service or by establishing a call connection for providing a second service. The method comprises the following steps performed by the first mobile terminal (1, 1a, 1b, 420): receiving (S21) a first indication signal (202) indicating that a service change towards the second service is temporarily unavailable from a mobile network node (31, 310) administrating an established call connection for providing the first service, and in response to receiving the first indication signal (202) refraining (S22) from requesting a service change towards the second service until reception of a further indication signal (204) from the mobile network node (31, 310) indicating that a service change is available again.
