  • Method for call establishment
    Patent number: 7158626
    Abstract: A call establishment method and corresponding communications terminal for a trunked radio network such as TETRA (708, 709) to establish a call from one network (700) to another network (711, 712, 730, 741) through a gateway (701, 713, 733, 740). A target telephone number is dialled at the calling communications terminal storing unique associations between telephone numbers and call types.

The gateway (701, 713, 733, 740) through which the target telephone number can be reached is then selected on the basis of the call type.
