The present invention concerns a method, a switching center, a converting
node, and a service control point for the transmission of service
signaling messages, with service signaling messages being transmitted in
sequences through a signaling network between switching centers (SW1, SW2,
SW3, SW6). The service signaling messages are each directed from an
originating switching center to a destination switching center using a
destination code and a converting node (CP) if necessary determines a
ported subscriber code assigned to the subscriber code. It is proposed
that the originating switching center determine a ported subscriber code
and enter it into the those signaling messages as destination code which
the originating switching center sends within a sequence of signaling
messages following a first signaling message.
