- Description: The IP Multimedia Subsystem (IMS) is a telecommunication middleware architecture that behaves as a docking station for a wide range of mul-timedia services. Several so-called killer applications have been envi-sioned for this platform such as multimedia group communications and location based services (LBS), but one of the most common business cases for IMS remains IPTV (Internet Protocol TV). Several IMS stand-ards development bodies and non-IMS players have contributed knowledge to the topic of IPTV, and the mechanisms needed to support various IPTV services are well understood. In addition, there are exam-ples of researchers who have implemented IPTV services in their net-work testbeds. However, many of them do not make use of the full power of the specifications which describe the mechanisms of service discovery and service selection. These processes define support for customer device configuration, service personalisation and service se-lection in a multi-service provider ecosystem. This position paper pro-poses solutions to some of the open questions in this area and pro-vides an architecture for a testbed that properly supports service dis-covery and selection. An initial implementation addressing the topic of auto-configuration of IMS terminals for service discovery is also pre-sented.

- Description: The IP Multimedia Subsystem is a telecommunications framework with a standard architecture for the provision of services. While the services themselves have not been standardised, standards do exist for basic technologies that can be re-used and aggregated in order to construct more complex services. These elements are called service capabilities by the 3GPP and service enablers by the OMA, both of which are repu-table standards bodies in this area. In order to provide re-usability, there is a need to manage access to the service capabilities. Also, in order to build complex services, there is a further need to be able to manage and coordinate the interactions that occur between service capabilities. The 3GPP and the OMA have separately defined network entities that are responsible for handling aspects of these requirements, and are known as a service capability interaction manager (SCIM) and a policy enforcer respectively. However, the internal structure of the SCIM and the policy enforcer have not been standardised by the relevant bodies. In addition, as the SCIM and the policy enforcer have been defined through complementary yet separate processes, there is an opportunity to unify efforts from both bodies. This paper builds on work and stand-ards defined by the bodies, and proposes the design of an interaction manager with features borrowed from both the SCIM and the policy en-forcer. To help validate the design, we have identified a platform known as JAIN SLEE which we believe conforms to the model proposed, and we discuss how JAIN SLEE can be used to implement our ideas.
