ROUTING OF A SERVICE REQUEST AIMED AT AN IMS SUBSCRIBER

摘要

A serving call server control function (S-CSCF) server in an IMS network is configured to receive a service request targeting a client device belonging to the IMS network and under the charge of the S-CSCF server. The S-CSCF server uses information elements contained in the service request to perform verifications, including: determining that the requested service is a telephone service; and determining that the user of the target client device targeted in the service request has not subscribed to a telephone service with the operator of the IMS network. If the result of the verifications is positive, the S-CSCF server directs the service request to a telephone network to which the target client device belongs. The server is applicable to subscribers of an IMS network benefiting from non-conversational services in packet mode from the IMS network, but having telephone services supplied thereto by a circuit-switched network.
