INFORMATION AND COMMUNICATION TECHNOLOGIES AIMING AT THE REDUCTION OF THEIR OWN ENERGY USE ## Abstract The present invention relates to methods and apparatuses for controlling commissioning of low-power devices in a wireless network by using at least two proxy devices, wherein a destination device selects from the at least two proxy devices a working proxy device and non-selected proxy devices enter a silence mode for a predetermined time period. The destination device stores an information indicating a previously selected working proxy device for quick reuse and more efficient selection. ## Claims ### Claim 1 A system for controlling commissioning of a network node, which is a Green Power node in a Zigbee network, wherein the system comprises: at least two proxy devices for forwarding commissioning messages through the network; and a sink device adapted to select from the at least two proxy devices a temporary master device for forwarding a commissioning response in the wireless network in response to the receipt of a channel request from the network node and to inform the at least two proxy devices about the selected temporary master device; wherein the at least two proxy devices are adapted to enter a silence mode not tunneling commissioning responses from the sink device to the network node for a predetermined time period if they are not selected as temporary master devices; and the sink device is further adapted to disregard a proxy device which corresponds to the stored identification in a subsequent selection of a temporary master device. ### Claim 2 (depends on 1) The system of claim 1, wherein the sink device is adapted to store an identification of the selected temporary master device and to use the stored identification for subsequent commissioning messages. ### Claim 3 (depends on 2) The system of claim 2, wherein the sink device is adapted to clear the stored identification information when all of the at least two proxy devices have been selected and tried as temporary master devices during a commissioning procedure. ### Claim 4 (canceled) ### Claim 5 An apparatus for controlling commissioning of a network node at a sink device in a wireless network, wherein the apparatus is adapted to select from at least two proxy devices a temporary master device for forwarding a commissioning response in the wireless network, in response to the receipt of a channel request from the network node and to inform the at least two proxy devices about the selected temporary master device; and the apparatus is further adapted to disregard a proxy device which corresponds to the stored identification in a subsequent selection of a temporary master device. ### Claim 6 (depends on 5) The apparatus of claim 5, wherein the apparatus is adapted to apply at least one of the following criteria for selection of the temporary master device: the highest link value contained in a commissioning notification message; among same link values, the highest received signal strength indicator; among same link values, the lowest short address. ### Claim 7 (depends on 5) The apparatus of claim 5, wherein the apparatus is adapted to control the sink device so as to add an identification of the selected temporary master device to the commissioning response and to broadcast or unicast the commissioning response to the at least proxy devices. ### Claim 8 (depends on 5) The apparatus of claim 5, wherein the apparatus is adapted to store an identification of the selected temporary master for subsequent commissioning messages or for use in a subsequent selection of a temporary master device. ### Claim 9 (depends on 5) The apparatus of claim 5, wherein the apparatus is adapted to clear the stored identification information when all of the at least two proxy devices have been selected and tried as temporary master during a commissioning procedure. ### Claim 10 A method of controlling commissioning of a network node at a sink device in a wireless network, wherein the method comprises selecting from at least two proxy devices a temporary master device for forwarding a commissioning response in the wireless network, in response to the receipt of a channel request from the network node; and informing the at least two proxy devices about the selected temporary master device; wherein the method further comprising disregarding a proxy device which corresponds to the stored identification in a subsequent selection of a temporary master device. ### Claim 11 (depends on 10) The method of claim 10, wherein the method comprises applying at least one of the following criteria for selection of the temporary master device: the highest link value contained in a commissioning notification message; among same link values, the highest received signal strength indicator; among same link values, the lowest short address. ### Claim 12 (depends on 10) The method of claim 10, wherein the method further comprises controlling the sink device so as to add an identification of the selected temporary master device to the commissioning response and to broadcast or unicast the commissioning response to the at least proxy devices. ### Claim 13 (depends on 10) The method of claim 10, wherein the method further comprises storing an identification of the selected temporary master working proxy for subsequent commissioning messages or for use in a subsequent selection of a temporary master device. ### Claim 14 (depends on 13) The method of claim 13, wherein the method further comprises clearing the stored identification information when all of the at least two proxy devices have been selected and tried as temporary master during a commissioning procedure. ### Claim 15 (depends on 10) A computer program product comprising code means for producing the steps of claim 10 when run on a computer device.
