Patent ID: 7164693

Claim:
A communication apparatus running a protocol stack implementation for interworking between a signaling source node and a signaling target node, comprising: a first protocol implementation unit for running a signaling control layer of the protocol stack on top of a packet transfer network for exchange of signaling data via at least one destination; a second protocol implementation unit for running a user adaptation layer of the protocol stack on top of said signaling control layer for support of signaling connection control services used by the signaling source node, wherein the user adaptation layer is selected from a group consisting of: a signaling connection control part (SCCP) user adaptation layer (SUA); a Message Transfer Part Level 3 (MTP3) user adaptation layer (M3UA) according to Signaling Transport (SIGTRAN) protocol stacks; an ISDN user adaptation layer (IUA); and a V5.2 user adaptation layer; and a name mapping unit for receiving a signaling target node name from said signaling source node and for mapping the signaling target node name into a destination.
