In a method according to one intelligent network recommendation, when B subscriber has hung up the phone, a Service Switching Point (SSP) sends a message to a Service Control Point (SCP) about the hanging up. The SCP responds with a request to disconnect the B leg. A separate request increases unnecessary signalling. In another known method, after B subscriber has hung up, a timer is started and the B leg is disconnected only after a set period of time. This waiting time is annoying to A subscriber, especially when there are many calls to be made. In the method according to the invention, A subscriber can make a continuing call without waiting or without causing unnecessary signalling so that after a Service Control Function (SCF) receives information about the break off of the call, it sends a message to a Service Switching Function (SSF) containing a request to collect the dialling by A subscriber relating to a new B subscriber. The Service Switching Function (SSF) directs the telephone network to disconnect the connection to B subscriber and create a connection to a new B subscriber. |
