Abstract: Systems, methods, and software for selecting among a plurality of IMS network slices. When an IP Multimedia Subsystem (IMS) network is partitioned into a plurality of IMS network slices, an IMS slice selection manager may be implemented at an edge of the IMS network slices. The IMS slice selection manager receives an IMS slice selection policy, and receives an IMS service request for an IMS service. The IMS slice selection manager selects an IMS network slice to provide the IMS service based on the IMS slice selection policy, and causes routing of the IMS service request to the selected IMS network slice.

Abstract: A method of handling user service profile information in a communications network, the communications network including a core network (CN) and a radio access network (RAN), includes receiving, at a first network element located in the CN, a first application status change message from a first mobile edge computing (MEC) server located in the RAN, the first application status change message indicating one or more applications currently running on the first MEC server; detecting a location update message received at the CN from a UE attached to the RAN; and in response to detecting the location update message, obtaining service profile data of the UE for at least one service corresponding to at least one of the one or more applications, and providing the obtained service profile data to the first MEC server.
