Abstract
Embodiments of the present invention provide a network entity of an IMS network, in which a registered user is being served by an assigned Serving-Call Session Control Function, S-CSCF. The network entity includes a memory storing data that includes an identity of at least one better-matching S-CSCF in the IMS network having capabilities better suited for serving the registered user than the assigned S-CSCF. The network entity is configured to obtain an indication of the availability of the better-matching S-CSCF, and when the better-matching S-CSCF entity is available to initiate a transfer so that the registered user is served by the better-matching S-CSCF. The network entity may be the assigned S-CSCF, or may be an I-CSCF. Embodiments of the present invention provide a method of transferring a registered user to a better-matching S-CSCF.
