Abstract
In a mobile communication networks system supporting IP Multimedia Subsystem, IMS, centralized services, there are provided measures for enabling/realizing an overlay implementation of a IMS centralized service network system taking into account a pool of network entities with different IMS centralized services capabilities. Such measures based on a IMS centralized-services applicability for a terminal requesting attachment and an IMS centralized-services capability of at least one switching entity out of a pool of switching entities which are configured to control radio resources for a same radio network area. In case of a mismatch between the IMS centralized-services applicability for the terminal and the IMS centralized-services capability of the switching entity the attachment request can be redirected to another switching entity out of said pool, which has a matching IMS centralized-services capability. Also, when receiving an attach request, a switching entity can be selected out of said pool, which has a matching centralized-services capability, and the requested attachment can be directed to the selected switching entity.
