Abstract
To achieve an improved support for introduction of server pools in packet networks and further to achieve transparency for applications the present invention provides a communication apparatus running a protocol stack implementation for interworking between a signaling source node and a signaling target node. The communication apparatus comprises a first protocol implementation unit (SCTP) adapted to run a signaling control layer on top of a packet transfer network (IP) for exchange of signaling messages via at least one signaling association. Further, the communication apparatus comprises a second protocol implementation unit (SUP, M3UA) adapted to run a user adaptation layer on top of the signaling control layer (SCTP) for support of signaling connection control services (RANAP) used by the signaling source node. A name mapping unit is adapted to receive a signaling target node name from the signaling source node and to map the signaling target node name into a peer signaling association.
