  • Patent number: 9071590
    Abstract: A method for a Personal Network Entity (PNE) to individually join a desired Personal Network (PN) is provided. When the PNE transmits a PN connection request message to a PN gateway, the PN gateway inserts its information into the connection request message and forwards the connection request message to a Converged Personal Network Service (CPNS) server. The CPNS server, upon receipt of the connection request message through the PN gateway, generates and manages information about a PN related to the PN gateway. The information about the PN is provided to the PNE at execution of authentication with the PNE, such that the PNE can determine whether to join the PN.
