Personalization-Based Optimization of Real-time Service Delivery in a Multi-Device Environment

Abstract

The success of future NGN services depends on the ability to adapt and personalize service delivery according to the user's context as well as service and device capabilities. Personalization includes not only respecting explicit user preferences, but also offering optimized multi-device communication. Flexible handling of multiple devices as well as multiple sessions is an increasing demand in the ubiquitous networking environment. In this paper, we describe how user preferences and device capabilitiy profiles for multiple devices can be managed and used for personalization. We integrated these methods into our earlierproposed Personalized Communication Controller (PCC), a Service Delivery Platform component for optimiziming multi-device communication through real-time decision-making. Information about related standardization efforts complements the paper.

Device discovery in future service platforms through SIP

“…Other efforts for personalization using SIP extensions include that by Kuhnen et al [1] who describe a method to manage user preferences and device capability profiles for a personalized multi-device environment. They use the IMS infrastructure and SIP PUBLISH messages for transmitting static and dynamic device capabilities described using the User Agent Profile (UAProf) [9] vocabulary.…”

“…Simultaneously, increasing device diversity and multiplicity offers opportunities as well as challenges for service delivery personalization. In such a scenario, Service Delivery Platforms (SDP) can offer flexible creation and delivery of multimedia services [1]. A SDP provides service management across content-based and session-based services, with network layer abstractions and agility in service provisioning.…”

Enabling context-sensitive communication experiences

“…Besides this technologydependent approach, there are some black box implementations in terms of a messaging gateway [14] or an Resource Availability Server (RAS) [15]. Although, the latter work has already evolved from a Converged IP Messaging (CPM)related project, the Personalized Policy Controller (PCC) that has been developed at the NEC Laboratories Europe [16], [17] rather considers the converged communication framework with focus on personalized multimedia communication.…”

Policy-Based Real-Time Decision-Making for Personalized Service Delivery

“…The first policy related to the scenario is becoming applicable when the session is received 2 at the PCC, and its obligation is directing the incoming session to a specific device which is available. The second policy is becoming applicable when the 2 The related action in the request is invite, as shown in Table I. new session is established 3 . Its obligation mutes the existing session.…”

“…Earlier [1], [2], we introduced a network component called Personalized Communication Controller (PCC), which allows for service-unspecific personalization of service delivery through dynamic resolution of capability interaction for device capabilities, user preferences and service capabilities. The PCC dynamically decides which devices to use for interactive sessions and is also capable of modifying running sessions (e.g.…”
