Abstract
An apparatus and method in a telecommunication system for controlling communication services between client terminals in a network. An application server hosting a core communication service communicates with the client terminals through an intermediate communication node in the network. The client terminals may be mobile terminals and the intermediate node may be a proxy call/session control function (P-CSCF) or a SIP application server (SIP-AS). A controller such as an IMS client controls transfer of communication sessions between the mobile terminals. The IMS client is divided into at least two parts, with one of the parts residing in the mobile terminal and the other part residing in the network.
