Abstract
A method for establishing a connection, either circuit-switched or packet-switched, between first and second mobile terminals of a telecommunications network and an associated switching node which includes a connection handler and a connection agent for each mobile terminal. To establish the connection, the connection handler determines if the connection agent for the first terminal is willing to transmit to the connection agent for the second terminal. If so, the first connection agent transmits a first endpoint address to the second connection agent. The connection handler determines if the second connection agent is willing to listen to the first connection agent and, if so, the first endpoint address is accepted by the second connection agent. A one-way connection between the first terminal and the second terminal in-which the first terminal can talk to the second terminal and the second terminal can listen to the first terminal is then established. The connection handler further determines if the second connection agent is willing to transmit to the first connection agent. If so, the second connection agent transmits a second endpoint address to the first connection agent. The connection handler determines if the first connection agent is willing to listen to the second connection agent and, if so, the first connection agent accepts the second endpoint address. A return connection between the first and second terminals in which the second terminal can talk to the first terminal and the first terminal can listen to the second terminal is then established.
