Claim:
1. An operating method of a control point device including a control unit, a display unit and a communication module, the operating method comprising: storing, through the control unit, network information on a first network; wherein the first network is a network to which the control point device is currently connecting, disconnecting from the first network; connecting to each of a plurality of connectable networks and collecting device information on at least one of a plurality of UPnP (Universal Plus and Play) or DLNA (Digital Living Network Alliance) control target devices connected to the each of the plurality of connectable networks; wherein the device information comprises network access information on networks to which the plurality of UPnP or DLNA control target devices belong, device discovery information on the plurality of UPnP or DLNA control target devices, and a stored content list of the plurality of UPnP or DLNA control target devices; returning to the first network based on the stored network information; displaying, through the display unit, the device discovery information, the network access information and the stored content list; receiving selection information on a selected content in the stored content list; checking a UPnP or DLNA control target device storing the selected content to determine whether the first network is the same as a second network, wherein the second network is a network to which the UPnP or DLNA control target device is currently connecting; displaying, through the display unit, a request message for requesting network movement permission when the first network is different from the second network; moving, through the communication module, from the first network to the second network when receiving a permission response to the request message; and receiving the selected content from the control target device and providing the selected content; wherein the first network corresponds to an infrastructure network (ISN) and the second network corresponds to a Wi-Fi direct network (WFDN), or wherein the first network corresponds to the WFDN and the second network corresponds to the ISN.
