Abstract
According to a first aspect of the present invention there is provided a method of handling an IP Multimedia Subsystem, IMS, session establishment request received from a calling party at a Multimedia Telephone Application Server, MMTel AS, within an IMS network from a Serving Call Session Control Function, S-CSCF, over an IMS Service Control, ISC, interface. The method comprises, within the MMTel AS: a) determining that said request is an originating call case request; b) establishing a first Multimedia Telephone, MMTel, service engine instance within the MMTel AS and using that first MMTel service engine instance to handle the request according to an originating call case; c) determining whether or not a called party associated with said request is served by said MMTel AS and, if so, establishing a second MMTel service engine instance within the MMTel AS, passing the request to said second MMTel service engine instance, and using the second MMTel service engine instance to handle the request according to a terminating call case; and d) forwarding said IMS session establishment request over said ISC interface to said S-CSCF, or to another S-CSCF serving the called party.
