Call establishment method

摘要

The invention concerns the method of establishing a communication connection (80) between a calling subscriber terminal (5) and a called subscriber terminal (61,62,63) connected to a circuit switched communication network (1), a terminal for a communication network and a server (15) for the provisioning of services to calling subscriber terminal (5) of a circuit switched communication network (1). A calling subscriber (91) enters a request to access a called subscriber terminal (62). The subscriber terminal (5) transfers an identification of the called subscriber to a mediation function element (16). The mediation function element (16) transmits said identification of the called subscriber to an address translation server (7). The address translation server (7) transmits a circuit switched network address of a terminal of the called subscriber to the mediation function element (16). The mediation function element (16) initiates a call establishment by passing said address to a call handling function (18) of the circuit switched communication network (1). <IMAGE>
