Abstract

The present invention relates to a communication system (SYS), a gateway apparatus (HiGA) and a method for allowing services of a first type provided by a communication server (IMS-S) to be provided to terminal devices (T1, T2, . . . Tn . . . TN) of a home network (CPN) independent of whether the terminal devices are of a first type or a second type (IMS-based or non-IMS-based). The gateway apparatus (HiGA) comprises one or more service-specific mapping applications (AS) for adapting the control plane (SIP) used between the second type terminal devices (T2) to the control plane (HTTP) used between the gateway apparatus (HiGA) and the communication server (IMS-S).
