Experiences and findings •  A big problem is the cost of front-end equipment: Gateways, Terminals, I/O-units. The

value of the service today is not high enough to motivate consumers to invest.

•  “Front end” of the system has to be designed in a flexible and modular way so it is easy and inexpensive to adapt to different customer needs.

•  Top 6 functionalities: –  Internet (Information) –  e-mail –  security –  comfort (bookings, lighting control) –  energy (display measurements) –  climate (temp, vent control)

•  Access operator independent

•  Low monthly costs

•  Customers demand high level of confidence in installation and support

•  The Concept to have a networked always on home/Internet Terminal in the kitchen has been very much appreciated by users.

•  Pay attention to the fact that it takes a lot of efforts and time to crate new value chains.

Services in the Gateway Service Description

AdministerSecurity Sends fire-, leakage- and burglary warnings. Burglar and Fire alarm is sent to SOS alarm central.

AutoLocking Activates different schemes when the apartment door is locked or unlocked, e.g. turn off water and gas.

DoorService Listens to the door if it is locked or not and sends the status to the back end when status changes.

StatisticAdministrator Collects the consumption values from the hotwater-, coldwater-, electricity- and gasdevices and sends the values every hour to the backend.

TemperatureService Listens to the value of the temperatursensor and sends new values to the back end..

VentilationControl Opens or closes the Ventilation Damper depending on status of the Fire- or Humidity sensors or doorlock.

LampSwitch Listens to the Lamp switch and turn on/off The hall-lamp when the status of the switch changes.

ControlService A bundle that listens for messages from the back end and activates or deactivates AdministerSecurity and AutoLocking services on the service gateway.

DaylightService Listen to the Daylight Sensor and sends a message to the back end if it changes from daylight to darkness or vice versa.

PowerOutlet Set power on/power of to controllable power outlets in the household. Is controllable by time values, random time, daylight and daylight in combination with random.

IndoorTemperatureScheme

Set the indoor temperature depending on the current scheme, daytype and AutoLocking status.

System Environment

  All Bundles in the Service Gateway are updated at the same time. No need for Bundles to react on update- and remove events from other Bundles.�

  The Service Gateway is an isolated environment. It is not possible for the end user to install or configure it.�

  No 3rd part installations of Bundles allowed.

Positive Experiences

  The OSGi API was an aid of a rapid start of development.

  A Use Case is conveniently translated to a Bundle.

  We did not have to set up ways of communicating between Bundles.

  We did not have to make tools for� - Remote Management � - Plattform Management� - User Management

  Support for security (PKI, HTTPS, SSH).

Negative Experiences

  Overhead and complexity.

  Framework have problems with releasing object references

  No support to control the Bundles start up order.

  No standardised way of external communication.

The Messenger problem

  Impossible to change the Messenger without essential recoding.

  Strict dependence of a Messenger supplier.

  Strict binding to protocol and network structure.

  Difficult to substitute Service Gateway HW.

  Essential that OSGi standardise the external communication.

E2 SGW Problem

3 important improvements of OSGi

1.  Standardize the messenger for external communication.

2.  Make a “low cost” version of the standard for implementation in native.

3.  Standardize a safe way to contact the Gateway from outside Internet.
