Slide title 40 pt Slide subtitle 24 pt Text 24 pt Bullets level pt Andreas Fasbender, Stefan Hoferer, Martin Gerdes, Takeshi Matsumura, Andreas Häber, Frank Reichert (18)  More and more electronic devices with integrated networking functionality  Clusters of networked devices in the private domains of the users (home/car/corporate LAN, phone PAN, etc.)  Local networks (e.g., based on DLNA) interconnected by IMS, XML Web Services and cloud computing technologies CE devices Consumers get networked

3 Top right corner for field-mark, customer or partner logotypes. See Best practice for example. Slide title 40 pt Slide subtitle 24 pt Text 24 pt Bullets level pt Andreas Fasbender, Stefan Hoferer, Martin Gerdes, Takeshi Matsumura, Andreas Häber, Frank Reichert (18) Personal networks get connected  High-speed fixed & mobile broadband access available anywhere  NGN with IMS as common service control layer gaining market traction  Consumers want services to be available across network boundaries and consumption devices –Communication services –Web access –Social networking –TV & music streaming –Video on demand etc.  Mix of operator-managed and user-managed services –QoS & charging if needed –Standard interfaces to Internet service providers  Mobile phone for personalization, authentication, service control etc. Personal Network Application Servers External Service Providers API

6 Top right corner for field-mark, customer or partner logotypes. See Best practice for example. Slide title 40 pt Slide subtitle 24 pt Text 24 pt Bullets level pt Andreas Fasbender, Stefan Hoferer, Martin Gerdes, Takeshi Matsumura, Andreas Häber, Frank Reichert (18) Requirements & features  Requirements –Trust relationship between user (device, identity), operator and remote environment, independent of service provider –Security, e.g. no uncontrolled exposure of remote appliances or requesting device –Support of off-the-shelf DLNA devices without SW modifications –Usage of remote devices under full control of administrator –Ease of use, no entering of complex bookmarks or addresses  Features –Authentication of users and service providers (IMS assumed) –Secure & easy-to-use relationship establishment between phone and remote environment (with and w/o LAN connectivity) –Discovery and control of remote devices by service provider –Service delivery into NAT-ed remote environments

7 Top right corner for field-mark, customer or partner logotypes. See Best practice for example. Slide title 40 pt Slide subtitle 24 pt Text 24 pt Bullets level pt Andreas Fasbender, Stefan Hoferer, Martin Gerdes, Takeshi Matsumura, Andreas Häber, Frank Reichert (18) Assumptions in the following  User has a mobile phone subscribed to and authenticated with mobile operator –Service delivery may be based on IMS signalling or not  User has subscription to operator media portal –However, remote access to home contents or delivery of 3 rd party services can be realized using the same architecture  User selects media services to be delivered into a CE device in a remote environment –Focus will be on DLNA devices only –Other devices can be supported with similar approach  Remote administrator grants the use of remote equipment –Examples: Coupon at hotel check-in, password in hotspot

8 Top right corner for field-mark, customer or partner logotypes. See Best practice for example. Slide title 40 pt Slide subtitle 24 pt Text 24 pt Bullets level pt Andreas Fasbender, Stefan Hoferer, Martin Gerdes, Takeshi Matsumura, Andreas Häber, Frank Reichert (18)  Pro‘s –Simple solution –UPnP control point on phone enables trick-play Request LAN access Alt 1: Phone with WiFi connectivity  Con‘s –Only works on phones with WiFi and UPnP/DLNA –Access contract with remote LAN provider required –No administrator control –No QoS  Relax local connectivity assumption, phone assumed to stay in WAN 1 Discover renderer 2 Navigate content directory 3 Initiate playout 4 Fetch media 5

9 Top right corner for field-mark, customer or partner logotypes. See Best practice for example. Slide title 40 pt Slide subtitle 24 pt Text 24 pt Bullets level pt Andreas Fasbender, Stefan Hoferer, Martin Gerdes, Takeshi Matsumura, Andreas Häber, Frank Reichert (18) Alt 2: Phone with cellular connectivity  Pro‘s –Full admininstrator control –Additional encryption of control URI possible –Works with standard Java phones with camera (or NFC...)  Con‘s –Requires residential control logic for port & URI mgmt. –No QoS, HTTP hickups with video services –No capability negotiation Add-on: RCD manages device list & capabilities, additional hand-shake Discover renderer 1 Fetch media 8 Fetch control URIs, e.g. _urn:schemas-upnp-org:service: AVTransport_control 4 Initiate playout (content URI) 7 Request port / external IP 2 Encode control URI 3 Navigate content directory 5 Request media (content & control URI) 6

Slide title 40 pt Slide subtitle 24 pt Text 24 pt Bullets level pt Andreas Fasbender, Stefan Hoferer, Martin Gerdes, Takeshi Matsumura, Andreas Häber, Frank Reichert (18) Pairing with remote environment  Several alternatives –Bluetooth or WiFi: Interoperability and security issues –NFC: Not (yet) wide-spread (except in Japan), requires hardware  Bar codes –Easiest to deploy (display, print, hand-out etc.) –Quicker penetration in mobile phones expected symbologies exist, standardization in OMA MCC (QR codes or Data Matrix, as widely used in Japan) Some issues with usability and capacity limitations, requires autofocus & integration in phone camera API

Slide title 40 pt Slide subtitle 24 pt Text 24 pt Bullets level pt Andreas Fasbender, Stefan Hoferer, Martin Gerdes, Takeshi Matsumura, Andreas Häber, Frank Reichert (18) Alt 3: Presence-based solution (1)  Residential control device integrated in gateway that hosts IMS termination (B2BUA, SIP UA, DLNA interworking) –Under standardization in HGI and TISPAN, ISIM optional –Natural control point for LAN (router, TR-069, DLNA MIU etc.)  Device capabilities & status published to PS –Administrator or user control which devices are exposed to whom IMS Gw Discover renderer 1 Encode IMPU & PS URI 3 Publish renderer (IMPU) 2 Fetch IMPU & PS URI 4 Navigate content (IMPU & PS URI) 5 Subscribe IMPU 6 Notify renderer 7

Slide title 40 pt Slide subtitle 24 pt Text 24 pt Bullets level pt Andreas Fasbender, Stefan Hoferer, Martin Gerdes, Takeshi Matsumura, Andreas Häber, Frank Reichert (18) Alt 3: Presence-based solution (2)  Con‘s –Requires IMS gateway control logic in remote LAN –Privacy management adds complexity  Pro‘s –Operator-managed, admin controlled configuration –Exposure to Internet SPs possible –Bookmarks for access to home and placeshift to 'known' LANs Initiate playout 10 Fetch media 11 IMS Gw Retrieve renderer info, request media playout 8 Invite renderer (optional QoS) 9 Most flexible solution, in line with Connected Home vision of HGI et al.

Slide title 40 pt Slide subtitle 24 pt Text 24 pt Bullets level pt Andreas Fasbender, Stefan Hoferer, Martin Gerdes, Takeshi Matsumura, Andreas Häber, Frank Reichert (18) Lessons learned in prototyping  Proximity solutions not yet properly implemented in mobile phones –Standardization and better phone integration required  Remote control of DLNA appliances requires DMR profile compliance –DLNA 1.5 certification starting  QoS support requires signalling and transcoding in gateway –Interworking with home QoS solutions, e.g. UPnP QoS –RTP support only optional in DLNA

Slide title 40 pt Slide subtitle 24 pt Text 24 pt Bullets level pt Andreas Fasbender, Stefan Hoferer, Martin Gerdes, Takeshi Matsumura, Andreas Häber, Frank Reichert (18) Conclusions  Proposed solutions enable relationship establishment between users, remote devices, and services –Widely deployable on today’s networks –Supporting off-the-shelf consumer appliances –Bar codes provide an interesting alternative for pairing a mobile phone with a remote environment and grant access for the user –Presence-based solution supports a wide range of other services  Tradeoff between –Security, flexibility, quality and ease of use on the one hand –Solution complexity and speed of deployment on the other  Standardization underway for most parts of the solution –Gaps on mobile phone side  Potential push for WS alternatives –HGI & TISPAN prepare the ground for proposed solution
