The invention relates to a method for performing a location updating from a mobile cellular radiophone system to another cellular radiophone system. To enable trunking of an incoming call to a terminal of a mobile system, the following steps are taken: (a) when the location area of said other system changes, said change is signalled to the mobile system (40), (b) an instruction is transmitted to the terminal (42) of the mobile system to initiate and perform an internal update procedure wherein said terminal (42) transmits to the mobile system (40) an indication of its presence, said step (b) being taken in respect of at least one terminal (42), (c) the internal update procedure of said other radiophone system is performed by the mobile station (44) of said other radiophone system in respect of said at least one terminal (42), and (d) the procedure is continued from step (b) in respect of the terminals (42) not yet updated. |
