Abstract
An apparatus and method for providing mobility to IMS sessions comprising connecting to an APN through a 3GPP access; determining if a non-3GPP access is available; determining if the APN is specific to an IMS application being used or desired to be used, or if an IP header of an IMS application flow matches a configured pattern; and performing one of: a) triggering an IMS Session Continuity flow through the non-3GPP access for the IMS application based on one of the following: if the APN is specific to the IMS application or if the IP header of the IMS application flow matches the configured pattern; or b) triggering an IP mobility flow through the non-3GPP access for the IMS application or a non-IMS application if the APN is not specific to the IMS application and if the IP header of the IMS application flow does not match the configured pattern.
