Abstract
A method of handling traffic within an IP Multimedia Subsystem, IMS, network. The method comprises registering an IMS user with a first Serving Call Session Control Function, S-CSCF, of the IMS network. Subsequently, at the first S-CSCF, a decision is made or instruction received to transfer said user to an alternative, second S-CSCF within the IMS network. A notification is sent from said first S-CSCF to a further IMS node, the notification including an explicit instruction to select a second S-CSCF and, upon receipt of said notification at the further IMS node, an S-CSCF reselection initiated for the user in order to select a second S-CSCF.
