Abstract
A communication apparatus running a protocol stack implementation for interworking between a signaling source node and a signaling target node provides improved support for introducing server pools in packet networks and for achieving transparency for applications. A first protocol implementation unit (SCTP) runs a signaling control layer on top of a packet transfer network (IP) for exchanging signaling messages via one or more signaling associations. A second protocol implementation unit (SUA, M3UA) runs a user adaptation layer on top of the signaling control layer SCTP for supporting signaling connection control services (RANAP) used by the signaling source node. A name mapping unit receives a signaling target node name from the signaling source node and maps the name into a peer signaling association.
