Inter-piconet communication

摘要

A method for a first device which is a member of a parent piconet and a child PNC of its child piconet to communicate with a second device existing in either the parent piconet or the child piconet, including the steps of generating a command frame to request a channel time for communication with the second device by use of an identifier to identify the piconet and the device ID uniquely allotted to a device and transmitting the generated command frame to a parent PNC, receiving the channel time allotted from the parent PNC to which the command frame has been transmitted, during which the first device and the second device are allowed for communication, and allowing data to be transmitted and received between the first device and the second device during the allotted channel time. Correct communication can be made between two devices although they have identical device IDs.
