There is provided a method of processing an IMS session originated by a UE after restart of a S-CSCF that was previously assigned to a user of the UE during registration with the IMS, when a further S-CSCF is currently assigned to the user. The method comprises, at a HSS, receiving a request to register a user identity of the user from the previously assigned S-CSCF, determining that the previously assigned S-CSCF is not the same as a S-CSCF currently assigned to the user, determining if IMS restoration procedures are supported for the UE, and, if IMS restoration procedures are not supported for the UE, sending a response to the previously assigned S-CSCF, the response identifying the further S-CSCF currently assigned to the user. |
