Abstract

Method and central server for handling of a framework shutdown in a network is disclosed. The method includes generating an event related to a framework shutdown. The method also includes converting the event as a Universal Plug and Play (UPnP) event. The method further includes delivering the converted event to one or more controllers present in the network. The central server includes a processor configured a processor configured to generate an event related to a framework shutdown and to convert the event as a Universal Plug and Play (UPnP) event. The central serve also includes a transmitter configured to deliver the converted event to one or more controllers present in the network.

Claims

1. A method for handling shutdown of a framework in a network, the method comprising:

if an event is generated, determining whether the event is related to one of an abrupt framework shutdown and a normal framework shutdown;

if the event is related to one of the abrupt framework shutdown and the normal framework shutdown, converting the event as a Universal Plug and Play (UPnP) event, and

delivering the converted event to one or more controllers present in the network; and

when the framework shutdown is determined to be the abrupt framework shutdown;

receiving by the framework a poll from an entity external to the framework at a regular interval of time, and

informing the one or more controllers of the abrupt shutdown,

wherein an exception that occurs during the framework shutdown is wrapped in a BundleException that is published as a framework event of type Frame-workEvent.Error.

2. The method of claim 1, further comprising decrementing a start-level of the framework to zero during the framework shutdown.

3. The method of claim 1, further comprising:

stopping a system bundle; and

stopping a plurality of active bundles.

4. The method of claim 3, further comprising recording a state of each of the plurality of active bundles at the shutdown, the state of each of the plurality of bundles indicates restarting point of each of the plurality of bundles when the framework is restarted.

5. The method of claim 3, wherein the stopping of the plurality of active bundles comprises shutting down the plurality of active bundles in a reverse dependency order.

6. The method of claim 1, wherein the framework is an Open Service Gateway initiative framework and the event is of type FrameworkEvent.SHUTDOWN.

7. A central server comprising:

a processor configured to generate an event related to a framework shutdown, to determine, when the event is generated, whether the event is related to one of an abrupt framework shutdown and a normal framework shutdown, and when the event is related to one of the abrupt framework shutdown and the normal framework shutdown, to convert the event as a Universal Plug and Play (UPnP) event;

a transmitter configured to deliver the converted event to one or more controllers present in a network; and

a receiver configured to receive a poll from an entity external to the framework at a regular interval of time, when the framework shutdown is determined to be the abrupt framework shutdown,

wherein the one or more controllers in the network are informed about an abrupt shutdown based on the poll, and

wherein an exception that occurs during the framework shutdown is wrapped in a BundleException that is published as a framework event of type Frame-workEvent.Error.

8. The central server of claim 7, wherein the transmitter and the receiver are integrated as a transceiver.

9. The central server of claim 7, wherein the processor is further configured to:

stop a system bundle; and

stop a plurality of active bundles.

10. The central server of claim 7, further comprising a memory module for storing a state of each of the plurality of active bundles at the shutdown, the state of each of the plurality of active bundles indicates restarting point of each of the plurality of bundles when the framework is restarted.

11. The central server of claim 7, wherein the framework is an Open Service Gateway initiative framework and the event is of type Frame-workEvent.SHUTDOWN.
