  1. Delivering Services to Residential Appliances by Utilizing Remote Resource Awareness Andreas Häber, PhD Research Fellow andreas.haber@uia.no University of Agder, Norway

  2. Agenda • Scenario overview • Remote service discovery & usage • Design approaches • Service delivery prototype NGMAST 2008 - Andreas Häber, Martin Gerdes, Frank Reichert, Andreas Fasbender, Ram Kumar

  3. Media control & delivery example • Thightly coupled control and media delivery • Workarounds: • Attach the device to an external display. • Manually transfer the media URI to a different device.

  7. Scenario overview & use cases Remote service discovery & usage Design approaches Service delivery prototype Agenda NGMAST 2008 - Andreas Häber, Martin Gerdes, Frank Reichert, Andreas Fasbender, Ram Kumar

  8. Presence framework • Specified by the IETF SIMPLE Wg • Presentity = Presence entity • Presence User Agents publish presence status for presentities to the Presence service • Presence watchers subscribe to PUAs’ identity for presence event • Presence event notifications include presence information for presentities • Example usage: 3GPP Presence Service (23.141) Presence service Presence User Agent Presence watcher Scope of the IETF presence protocols Presentity NGMAST 2008 - Andreas Häber, Martin Gerdes, Frank Reichert, Andreas Fasbender, Ram Kumar

  9. Service Presence for Remote Service Awareness • Commonly presentities happen to be people • What about residential services? • Need to add service specific information to the presence notification data. • Reuse existing extensions • For example GEOPRIV to easily put services on a map. Presence service Presence User Agent Presence watcher Scope of the IETF presence protocols UPnP, Bonjour / ZeroConfig, Bluetooth, … Presentity NGMAST 2008 - Andreas Häber, Martin Gerdes, Frank Reichert, Andreas Fasbender, Ram Kumar

  10. Remote service usage sessions SDP messages specify the residential service(s) to be involved; one media descriptor for each service - (External) IP address and port number to communicate with the service NGMAST 2008 - Andreas Häber, Martin Gerdes, Frank Reichert, Andreas Fasbender, Ram Kumar

  11. Establishing a service invocation sesssion Session Description offer v=0 o=visited.sdg 3380446179 3380446179 IN IP4 192.168.168.31 s=- c=IN IP4 192.168.168.31 t=0 0 a=sendonly m=application 9 TCP piranha a=udn:uuid:9afb3231-345a-4cd1-b448-8866b79ff91b a=setup:active  Requested service – the UDN is discovered from service presence (i.e., NOTIFY requests from SPS) Session Description answer v=0 o=home.sdg 3380446179 3380446179 IN IP4 192.168.168.32 s=- c=IN IP4 192.168.168.32 t=0 0 a=recvonly m=application 9000 TCP piranha a=udn:uuid:9afb3231-345a-4cd1-b448-8866b79ff91b a=setup:passive  Basically its external IP address Port number associated with this session to use the service  source: Ericsson-UiA ONE Project NGMAST 2008 - Andreas Häber, Martin Gerdes, Frank Reichert, Andreas Fasbender, Ram Kumar

  13. Pre-selection of the target device Step 1 The user selects the target device in a control application. Step 2-3 In the service provider’s web application the user selects the desired content. Step 4-5 The web application establishes a session with the tharget device, via the Service Discovery Gateway. Step 6 The service controls the Digital Media Player. NGMAST 2008 - Andreas Häber, Martin Gerdes, Frank Reichert, Andreas Fasbender, Ram Kumar

  14. Post-selection of the target device (1/2) gateway alternative Step 1-2 User opens start page of the service and selects content. Step 3 Service requests to establish a session with the user. Step 4 Based on ad-hoc mechanism user selects DMP. Step 5 Routes media to the DMP and controls it. NGMAST 2008 - Andreas Häber, Martin Gerdes, Frank Reichert, Andreas Fasbender, Ram Kumar

  15. Post-selection of the target device (2/2) refer alternative Step 1-3 Same as for the gateway alternative. Step 3.x User refers the service to an SDG (+ device information). This SDG should handle the request by setting up remote connectivity. Step 4-5 Trickplay via web application – service can directly control the DMP. Indirectly: Refer to SPS instead which will proxy to the SDG. NGMAST 2008 - Andreas Häber, Martin Gerdes, Frank Reichert, Andreas Fasbender, Ram Kumar

  16. Integrated selection of the target device Step 1 User opens start page of the service. User’s IMPU is used to fetch available media renderers from SPS Step 2-3 Selection Step 4 Trickplay NGMAST 2008 - Andreas Häber, Martin Gerdes, Frank Reichert, Andreas Fasbender, Ram Kumar

  17. Comparison of the design approaches NGMAST 2008 - Andreas Häber, Martin Gerdes, Frank Reichert, Andreas Fasbender, Ram Kumar

  18. Agenda • Scenario overview & use cases • Remote service discovery & usage • Design alternatives • Service delivery prototype NGMAST 2008 - Andreas Häber, Martin Gerdes, Frank Reichert, Andreas Fasbender, Ram Kumar

  19. Display Image Service – signaling flow NGMAST 2008 - Andreas Häber, Martin Gerdes, Frank Reichert, Andreas Fasbender, Ram Kumar

  20. Future work • Privacy and Security • What is published about your residential environment? • User controlled topology hiding • Leverage inherent Presence framework capabilities • Scalability • Optimization of service presence information with regards to the number and size of messages exchanged. NGMAST 2008 - Andreas Häber, Martin Gerdes, Frank Reichert, Andreas Fasbender, Ram Kumar
