Abstract

A method of synchronizing state information of a home wireless system wherein the home wireless system comprises a plurality of peripheral wireless nodes (14; 16; 19; 21; 23) and a first gateway (12) having wireless communication means for communicating with and controlling associated peripheral wireless nodes, the method comprising the steps installing at least one second gateway (26) in said home wireless system, assigning peripheral wireless nodes to said first gateway (12) or anyone of said at least one second gateway (12′), and each gateway directing each assigned peripheral wireless node to communicate with an assigned gateway, receiving in a first gateway system state affecting input message from an associated peripheral wireless node, determining in said first gateway a resulting system state based on said input, and communicating said resulting system state as a state change message from said first gateway to said at least one second gateway.

Claims

1. A method of synchronizing state information, including arming state and alarm state, of a home wireless system wherein the home wireless system comprises a plurality of peripheral wireless nodes and a first gateway having wireless communication means for communicating with and controlling associated peripheral wireless nodes, the method comprising the steps:

a) installing at least one second gateway in said home wireless system, each gateway acting as a system or network controller in a home or a building in communications with external systems,

b) assigning peripheral wireless nodes to said first gateway or anyone of said at least one second gateway, and each gateway directing each assigned peripheral wireless node to communicate with an assigned gateway,

c) receiving in a first gateway system state affecting input message from an associated peripheral wireless node,

d) determining in said first gateway a resulting system state based on said input, and

e) communicating, when said system state affecting input is included in a first set of predefined input messages, said resulting system state as a state change message from said first gateway to said at least one second gateway so as to ensure that the home wireless system represents a unitary state.

2. A method as claimed in claim 1, also comprising communicating resulting system state only if said system affecting input is included in a first set of predefined input messages.

3. A method as claimed in claim 2, wherein said first set of predefined input messages include entry alarms and arming state.

4. A method as claimed in claim 2, also comprising including a time stamp associated to the actual time of system state change.

5. A method as claimed in claim 1, also comprising including in said state change a message digest of the resulting state.

6. A method as claimed in claim 2, also comprising including in said state change a message digest of the resulting state.

7. A method as claimed in claim 1, also comprising marking said state change message with a time stamp representative of said resulting system state change.

8. A method as claimed in claim 2, also comprising marking said state change message with a time stamp representative of said resulting system state change.

9. A method as claimed in claim 8, also comprising selecting the resulting system state change having the newest time stamp as valid where conflicting application state information is detected in a gateway.
