Abstract

A home wireless system and a method of controlling it wherein the home wireless system comprises a plurality of wireless peripheral nodes (14; 16; 19; 21; 23) and a first gateway (12) having wireless communication means for communicating with and controlling wireless peripheral nodes. The method comprises: a) installing at least one second gateway (12′, 32) in said home wireless system, b) binding wireless peripheral nodes to said first gateway (12) or anyone of said at least one second gateway (12′, 32), c) each wireless peripheral node repeatedly sending messages to the bound gateway, d) said bound gateway sending an acknowledge message as a response to the message received from the wireless peripheral node, e) each wireless peripheral node initiating a searching process for an available gateway among said first and said at least one second gateway if not receiving an acknowledge message from the bound gateway, said searching process including a link establishment process, and f) proceeding said link establishment process in a responding gateway by binding said searching wireless peripheral node to communicate with the responding gateway. The at least one second gateway (12′, 32) is provided with wireless communication means for communicating with and controlling wireless peripheral nodes.

Claims

1-8. -8. (canceled)

9. A method of controlling a home wireless system wherein the home wireless system comprises a plurality of wireless peripheral nodes and a first gateway having wireless communication means for communicating with and for controlling wireless peripheral nodes, the method comprising the steps:

a) installing at least one second gateway in said home wireless system,

b) binding wireless peripheral nodes to said first gateway or anyone of said at least one second gateway in a link establishment process, each gateway directing each bound wireless peripheral node to communicate with the bound gateway,

c) each wireless peripheral node repeatedly sending messages to the gateway it is bound to,

d) said bound gateway sending an acknowledge message as a response to the message received from the wireless peripheral node,

e) each wireless peripheral node initiating a searching process for an available gateway among said first and said at least one second gateway if not receiving an acknowledge message from the bound gateway, said searching process including a link establishment process, and

f) proceeding said link establishment process in a responding gateway by binding said searching wireless peripheral node to communicate with the responding gateway by transmitting a set of temporary encryption keys from the gateway to the wireless peripheral node and using in said wireless peripheral node said set of temporary encryption keys when sending messages.

10. A method as claimed in claim 9, wherein said searching process includes broadcasting from the wireless peripheral node an identification message and transmitting from the responding gateway a login request message.

11. A method as claimed in claim 10, including in the identification message node address data and transmitting from the responding gateway a login request message including said node address data.

12. A method as claimed in claim 9, wherein at least one of said first gateway and said at least one second gateway repeatedly connect to a central monitoring station comprising data storing means storing installation data, and wherein said central monitoring station updates at least one of said first gateway and said at least one second gateway when installation data are changed.

13. A method as claimed in claim 12, wherein said first gateway and said at least one second gateway repeatedly broadcast an installation data message, so as to allow an updated gateway to update other gateways present in the home wireless system.

14. A home wireless system comprising

a plurality of wireless peripheral nodes and a first gateway having wireless communication means for communicating with and controlling wireless peripheral nodes, and

at least one second gateway (12′

, 32) having wireless communication means for communicating with and controlling wireless peripheral nodes, each gateway (12, 12′

, 32) comprising a central unit (44) with memory means for maintaining temporary encryption keys,

wherein each wireless peripheral node is bound to either of said first gateway (12) and said at least one second gateway (12′

, 32) by using a temporary encryption key received from the gateway it is bound to in all communications in both directions.

15. A home wireless system as claimed in claim 14, wherein said first gateway (12) and said at least one second gateway (12;

32) are connected to a central monitoring station (22) comprising data storing means (28) storing installation data, said central monitoring station (22) updating said first gateway (12) and said at least one second gateway (12;

32) when installation data are changed.
