Abstract

Methods and computer-readable mediums are provided. For example, in one method a request is initiated for a security event update. Thereafter, a last received event identification (“LREI”) for at least one event type is retrieved from memory and inserted a security event update request. The request is transmitted as a polling signal towards a device (e.g., a server or remote client). In another method, a request signal containing is received. An LREI for an event type is extracted from the request. The LREI is compared to an event identification stored in memory. The results are inserted into a response. An indication, is inserted into the response, that at least one event identification is greater than said LREI and is not inserted in the response. The response is transmitted. In yet other embodiments, the computer-readable mediums and systems are also provided which perform similar features recited by the above methods.

Claims

1. A method comprising:

initiating, at a remote client, a security event update request for a security system coupled to a building;

retrieving, at the remote client, a stored last received event identification (“

LREI”

) for an event type, wherein an event identification is a unique, increased, and ordered identifier that is assigned to and associated with an event when the event occurs, and wherein said LREI is the event identification associated with a last event received by the remote client for the event type;

inserting said LREI for said event type into said security event update request; and

transmitting said security event update request as a polling signal from the remote client towards a server.

2. The method of claim 1, wherein said security event update request comprises extensible markup language (“

XML”

).

3. The method of claim 1, further comprising:

receiving a reply at the remote client;

extracting a security event from said reply;

comparing the event identification associated with said extracted security event to said LREI;

updating said LREI to the event identification associated with said extracted security event when the event identification associated with said extracted security event is greater than said LREI; and

initiating a polling request from the remote client towards the server when said reply indicates that other events were not transmitted in said reply.

4. The method of claim 3, further comprising:

repeating said extracting, said comparing, and said updating when more events are in said reply.

5. The method of claim 1, further comprising:

receiving a reply at the remote client;

extracting a first security event from said reply;

updating said LREI with the event identification associated with said first security event;

extracting a second security event from said reply;

updating said LREI with the event identification associated with said second security event when the event identification associated with said second security event is greater than said LREI;

initiating a polling request when said reply indicates that other events were not transmitted in said reply.

6. The method of claim 5, further comprising:

extracting a third security event from said reply; and

updating said LREI with the event identification associated with said third security event when the event identification associated with said third security event is greater than said LREI.

7. A method comprising:

receiving, at a server, a security event update request signal for a security system that is coupled to a building;

extracting a last received event identification (“

LREI”

) from said request signal, wherein an event identification is a unique, increased and ordered identifier that is assigned to and associated with an event when the event occurs, and wherein said LREI is the event identification associated with a last event received by a remote client for an event type;

comparing said LREI to an event identification associated with an event of the event type stored in memory at the server;

inserting results of said comparison into a response when said event identification is greater than said LREI;

inserting an indication in said response that more events of the event type exist, if at least one event identification associated with an event of the event type is greater than said LREI and is not transmitted in said response; and

transmitting said response.

8. The method of claim 7, wherein said response is in extensible markup language (“

XML”

).

9. The method of claim 7, wherein said indication is a flag.

10. A non-transitory computer-readable medium having stored thereon a plurality of instructions, the plurality of instructions including instructions which, when executed by a processor of a remote client, cause the processor to perform the steps comprising:

initiating, at a remote client, a security event update request for a security system coupled to a building;

retrieving, at the remote client, a stored last received event identification (“

LREI”

) for an event type, wherein an event identification is a unique, increased, and ordered identifier that is assigned to and associated with an event when the event occurs, and wherein said LREI is the event identification associated with a last event received by the remote client for the event type;

inserting said LREI for said event type into said security event update request; and

transmitting said security event update request as a polling signal from the remote client towards a server.

11. The non-transitory computer-readable medium of claim 10, wherein said security event update request comprises extensible markup language (“

XML”

).

12. The non-transitory computer-readable medium of claim 10, further comprising:

receiving a reply at the remote client;

extracting a security event from said reply;

comparing the event identification associated with said extracted security event to said LREI;

updating said LREI to the event identification associated with said extracted security event when the event identification associated with said extracted security event is greater than said LREI; and

initiating a polling request from the remote client towards the server when said reply indicates that other events were not transmitted in said reply.

13. The non-transitory computer-readable medium of claim 10, further comprising:

repeating said extracting, said comparing, and said updating when more events are in said reply.

14. The non-transitory computer-readable medium of claim 10, further comprising:

receiving a reply at the remote client;

extracting a first security event from said reply;

updating said LREI with the event identification associated with said first security event;

extracting a second security event from said reply;

updating said LREI with the event identification associated with said second security event when the event identification associated with said second security event is greater than said LREI; and

initiating a polling request when said reply indicates that other events were not transmitted in said reply.

15. The non-transitory computer-readable medium of claim 14, further comprising:

extracting a third security event from said reply; and

updating said LREI with the event identification associated with said third security event when the event identification associated with said third security event is greater than said LREI.

16. A non-transitory computer-readable medium having stored thereon a plurality of instructions, the plurality of instructions including instructions which, when executed by a processor of a server, cause the processor to perform the steps comprising:

receiving, at the server, a security event update request signal for a security system that is coupled to a building;

extracting a last received event identification (“

LREI”

) for an event type from said request signal, wherein an event identification is a unique increased and order identifier that is assigned to and associated with an event when the event occurs, and wherein said LREI is the event identification associated with a last event received for an event type;

comparing said LREI to an event identification associated with an event of the event type stored in memory at the server;

inserting said results into a response when said event identification is greater than said LREI;

inserting an indication in said response that more events of the event type exist, if at least one event identification associated with an event of the event type is greater than said LREI and is not transmitted in said response; and

transmitting said response.

17. The non-transitory computer-readable medium of claim 16, wherein said indication is a flag.

18. The non-transitory computer-readable medium of claim 16, wherein said response comprises extensible markup language (“
