发明名称 NAT address translation device traversal for signalling messages according to the SIP protocol
摘要 <p>The method involves transmitting signaling messages (fs) passing through network address translation equipments (NAT1, NAT2), and exchanging physical addresses of calling and called communication clients (C1, C2) for establishing a communication session (fm). The client (C1) provides a parameter e.g. header, representative of implementation of a network address translation traversal solution of the clients, within the message. Network equipments of a telecommunication network do not implement a clear traversal solution of the translation equipments, during the presence of the parameter. Independent claims are also included for the following: (1) a communication client comprising a transmitting unit (2) a telecommunication network comprising a network equipment (3) a computer program comprising a set of instructions to perform a method for establishing a communication session between calling and called communication clients.</p>
