Responder device binding in a wireless system

A method for use in a wireless personal area network (WPAN) comprising an initiator device and a plurality of responder devices which can bind with the initiator device, characterized in that the method comprises, at one of the plurality of responder devices:

• receiving a discovery request from the initiator device;
• forming a discovery response;
• and
• sending the discovery response to the initiator device, wherein the step of forming the discovery response comprises:
• collecting at least two parameters, which comprise at least one of the following:
• a parameter indicating whether a line of sight connection exists between the initiator device and the responder device;
• a parameter indicating that the responder device is within a predetermined range of the initiator device;
• a parameter indicating that the responder device is not yet bound with any other device;
• a parameter indicating a time period since the responder device was rebooted, or indicating that a predetermined time period has elapsed since the responder device was rebooted;
• a parameter indicating that the responder device is currently in an operating state to form a binding;
• and
• a parameter indicating that the initiator device is a default controller for the responder device;
• computing a score using the at least two parameters, the score being indicative of a likelihood of the initiator device wanting to bind with the responder device;
• including the score as an element of the discovery response;
• and
• including a duplicate score handling element, which indicates one of a plurality of actions to be taken by the initiator device in the event that another responder device has the same score as the responder device.
