Patent number: 5613201Abstract: A method and apparatus for placing calls in a multi-system land mobile radio network. A plurality of call destinations are linked or grouped together into a call group. Each call destination has a preferred system. Selection of a first call destination points to or is linked to at least a second call destination.
