UPnP control point for mobile phones in residential networks
2006
Together, Ericsson and HiA are studying the role of WiFi-enabled mobile phones in residential networks. This article describes a first step to allow mobile phones to discover and control networked residential media servers and renderers following the standards developed by the UPnP Forum.
Media Delivery to Remote Renderers Controlled by the Mobile Phone
2009
In today's content delivery solutions, service delivery and control are still tightly coupled, a service typically being delivered to the same device that controls the session. We present a solution that was designed with the goal to decouple service control and delivery. Using our approach, multimedia streaming services can be delivered to off-the-shelf DLNA devices in visited networks. The service provider receives information about the remote media player and access environment via a mobile phone. Proximity technologies (e.g. barcodes, NFC) of the control device are used for the exchange of required credentials. This paper describes a typical scenario and our prototype implementation.
Delivering Services to Residential Appliances by Utilizing Remote Resource Awareness
2008
Service providers are nowadays offering a variety of services, and in particular multimedia content delivery. Besides, consumer appliances are increasingly becoming digitalized including support for communication networks. However, it is difficult, and in many cases impossible, to use these services with standard consumer appliances, such as TV and media player devices. Rather, usage is often restricted so that they can only be accessed through web browsers from PCs, mobile phones and similar terminals. This is unfortunate, because dedicated consumer appliances are often better suited to handle the content and thereby give consumers a better experience. Within this paper, three design appro…
Towards a relation oriented service architecture
2010
Over the past three decades, the Internet has evolved from a point to point, open, academic network to an applications and services oriented critical infrastructure. The Internet has become a vital component of society today, from its simple origin as an academic research project. During this transition, numerous applications and usages of the network emerged that cannot be efficiently implemented by adhering to the original design tenets of the Internet. Some of the tenets have been broken, others diluted and new ones are emerging to accommodate new paradigms. Moreover, applications and services have been moving slowly but consistently towards a uniform model based on Service Oriented Appr…
Virtualization of Remote Devices and Services in Residential Networks
2009
Lately solutions for remote access for residential services have been proposed. However, these solutions require modifications to the service controllers. In addition, remote access adds complexity to the client application. We propose here a solution for decoupling remote access from the client itself with an entity that creates virtual instances of remote services in a local network. Thereby, clients will be able to discover the virtual instance and use it. Moreover, client applications do not need to distinguish between local and remote services hence reducing complexity.
Phone-Controlled Delivery of NGN Services into Residential Environments
2008
The horizontally layered architecture of the IMS/NGN standards family enables the delivery of services independent of access network and requesting device. In this article, the authors propose a further separation of service control and delivery, allowing the requesting device - in particular a user's mobile phone - to invite other devices (we will focus on DLNA appliances) into the service delivery, enhancing both user experience and service design flexibility. The proposed solution builds on exploiting proximity technologies (e.g. barcodes, NFC) for pairing the control device with a remote environment. Motivated by scenarios, the architecture concepts are explained and a prototype that wa…
Using SIP Presence for Remote Service Awareness
2008
Residential networks usually protect its devices and services behind firewalls and use private IP addresses. Therefore, appliances within a residential network cannot be discovered and utilized from external networks by standardized technologies as UPnP. In this paper, we present our concept of “Service Presence”, based on the 3GPP Presence Service that makes the service presence information remotely discoverable.
Remote service usage through SIP with multimedia access as a use case
2007
The IP Multimedia Subsystem is under deployment, as an IP-based service control and access infrastructure, but how it interconnects with residential appliances is currently unclear. With IMS access for the residential appliances they can be used as both service consumers and service providers. In this paper we present a protocol which allows residential services to be remotely invoked, through the IMS, and consumed in a different network, along with a prototype implementation and early results. With our protocol services of two distinct service protocol systems can cooperate.

Evaluation of frameworks for creating end-to-end mobile services with OMA MMS as a use case
2005
Masteroppgave i informasjons- og kommunikasjonsteknologi 2005 - Høgskolen i Agder, Grimstad Several frameworks are available in 3GPP networks to create mobile services, such as the Open Service Access (OSA) Application Programming Interface (API) and the native Session Initiation Protocol (SIP). Each of these frameworks has their own advantages and disadvantages. Therefore it is important for a service to use a framework which suits its own requirements as best as possible. In this thesis we have defined a use case, TMMS Service. This use case has been designed for four frameworks selected, which are: GPRS, IMS, OSA API and OSA Parlay X Web Services. We have then evaluated the design of the…
“Sven and the Media Portal” : A Nomadic Use Case for the Extended Home
2006
The Networked and Electronic Media Technology Platform (NEM) [5] states that users will consume an “innovative mix of various media forms, delivered seamlessly over technologically transparent networks, to improve the quality, enjoyment and value of life. [6] visualizes a future use case and some of the challenges that need to be addressed before the NEM vision becomes reality.
