Call establishment method
First Claim
1. A method for establishing a communication connection between a calling subscriber terminal and a called subscriber terminal connected to a communication network, the method comprising the steps of:
- entering, at the calling subscriber terminal, a first request to access the called subscriber terminal;
transferring an identification of a called subscriber to a mediation function element;
transmitting said identification of the called subscriber from the mediation function element to an address translation server;
transmitting a circuit switched network address of a terminal of the called subscribers from the address translation server to the mediation function element; and
initiating a call establishment by passing said address from the mediation function element to a call handling function of the communication network.

Abstract
Summary The invention concerns the method of establishing a communication connection between a calling subscriber terminal and a called subscriber terminal connected to a circuit switched communication network, a terminal for a communication network and a server for the provisioning of services to calling subscriber terminals of a circuit switched communication network. A calling subscriber enters a request to access a called subscriber terminal. The subscriber terminal transfers an identification of the called subscriber to a mediation function element. The mediation function element transmits said identification of the called subscriber to an address translation server. The address translation server transmits a circuit switched network address of a terminal of the called subscriber to the mediation function element. The mediation function element initiates a call establishment by passing said address to a call handling function of the circuit switched communication network.

2. A terminal for a communication network, the terminal comprising a first function element for establishing circuit switched connections to called subscriber terminals over the communication network,
wherein the terminal comprising: - a second function element for receiving a request to access one or several called subscriber terminals and for transferring an identification of a called subscriber to a mediation function element; and
a mediation function element for receiving the identification of the called subscriber from the second function element;
transmitting said identification of the called subscriber from the mediation function element to an address translation server;
receiving from the address translation server a circuit switched network address of a terminal of the called subscriber and initiating a call establishment by passing said address through the first function element to a call handling function of a circuit switched network. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9)
- a second function element for receiving a request to access one or several called subscriber terminals and for transferring an identification of a called subscriber to a mediation function element; and
-
10. A server for the provisioning of services to calling subscriber terminals connected over a communication network with called subscriber terminals,
wherein the server comprising at least one mediation function element for: receiving requests from calling subscriber terminals, a request transmits at least one identification of a called subscriber from a subscriber terminal to the mediation function;
transmitting the identification of the called subscriber to an address translation server;
receiving from the address translation server a circuit switched network address of a terminal of the called subscriber; and
initiating a call establishment by passing that circuit switched network address to a call handling function of the communication network.
