As shown in FIG. 2A, there are merely the CPNS server 110, and the PNGW 120, and one PNE 230 in the CPNS enabler. In the embodiment, to begin, the CPNS server 110 transmits a device capabilities query request message SQ1 to the PNGW 120, wherein the device capabilities query request message SQ1 comprises a target ID (Identification). Then, if the target ID does not indicate the PNGW 120, the PNGW 120 relays the device capabilities query request message SQ1 to other elements. Next, if the target ID indicates the PNE 230, the PNE 230 receives the device capabilities query request message SQ1 through the PNGW 120 and then transmits a device capabilities query response message SR1 to the PNGW 120, wherein the device capabilities query response message SR1 is generated by the PNE 230 according to a PNE capability of the PNE 230. Finally, the PNGW 120 relays the device capabilities query response message SR1 to the CPNS server 110. For example, the PNE 230 may have the PNE capability as an MP3 player, an Internet browser, or a mobile phone.

FIG. 2B is a diagram for illustrating message transmission according to another embodiment of the invention. In the embodiment, to begin, the CPNS server 110 transmits a device capabilities query request message SQ2 to the PNGW 120, wherein the device capabilities query request message SQ2 comprises a target ID. If the target ID indicates the PNGW 120, the PNGW 120 receives the device capabilities query request message SQ2 and then transmits a device capabilities query response message SR2 to the CPNS server 110, wherein the device capabilities query response message SR2 is generated by the PNGW 120 according to a PNGW capability of the PNGW 120. For example, the PNGW may have the PNGW capability as an MP3 player, an Internet browser, or a mobile phone. It is noted that the CPNS server 110 may transmit the device capabilities query request messages SQ1, SQ2 at intervals (e.g., periodically) or when the CPNS server 110 is initiated. In some embodiments, the CPNS server 110 may also transmit the device capabilities query request messages SQ1, SQ2 once a user input is received (not shown).

The message ID indicates a serial number, the target ID indicates which sends the device capabilities query response message (e.g., PNGW or the PNE sends), and the device capability comprises a UI (User Interface) capability and an external capability. The UI capability comprises a Boolean value indicating whether the PNE or the PNGW supports a UT function, and the external capability comprises an XML (Extensible Markup Language) fragment indicating a device type and/or a video codec of the PNGW or the PNE.

FIG. 4A is a diagram for illustrating message transmission according to an embodiment of the invention. As shown in FIG. 4A, there are merely the CPNS server 110, and the PNGW 120, and one PNE 230 in the CPNS enabler. In the embodiment, when a PNE capability of the PNE 230 changes (e.g., the memory of the PNE 230 increases), the PNE 230 transmits a device capabilities change notification message SC1. Then, the PNGW 120 relays the device capabilities change notification message SC1. Next, the CPNS server 110 receives the device capabilities change notification message SC1 through the PNGW 120 and then transmits a device capabilities change notification confirm message SM1 to the PNGW 120, wherein the device capabilities change notification confirm message SM1 comprises a target ID indicating the PNE 230. Finally, because the target ID indicates the PNE 230, the PNGW 120 relays the device capabilities change notification confirm message SM1 to the PNE 230.

FIG. 4B is a diagram for illustrating message transmission according to another embodiment of the invention. In the embodiment, when a PNGW capability of the PNGW 120 changes (e.g., the memory of the PNGW 120 increases), the PNGW 120 transmits a device capabilities change notification message SC2. Then, the CPNS server 110 receives the device capabilities change notification message SC2 and then transmits a device capabilities change notification confirm message SM2 to the PNGW 120, wherein the device capabilities change notification confirm message SM2 comprises a target ID indicating the PNGW 120.

The UI capability comprises a Boolean value indicating whether the PNE or PNGW supports a UI function, and the external capability comprises an XML (Extensible Markup Language) fragment indicating a device type and/or a video codec of the PNGW or the PNE.

FIG. 5B is a table for illustrating the device capabilities change notification confirm message according to an embodiment of the invention. As shown in FIG. 5B, each of the device capabilities change notification confirm messages SM1, and SM2 comprise a message ID and a target ID. The message ID indicates a serial number, and the target ID indicates to send the device capabilities change notification confirm message to the PNE or the PNGW.

FIG. 6 is a flowchart for illustrating a method of an OMA according to an embodiment of the invention. To begin, in step S610, a device capabilities query request message which comprises a target ID (Identification) is transmitted by a CPNS (Converged Personal Network Service) server. In step S620, in which the target ID indicates, a PNE (Personal Network Element) or the PNGW, is checked by a PNGW (Personal Network Gateway). If the PNE is indicated, in step S630, the device capabilities query request message is relayed by the PNGW. In step S640, the device capabilities query request message is received through the PNGW by the PNE. In step S650, a first device capabilities query response message to the PNGW is transmitted according to a PNE capability of the PNE by the PNE. Finally, in step S660, the first device capabilities query response message is relayed to the CPNS server by the PNGW. On the other hand, if the PNGW is indicated, in step S670, the device capabilities query request message is received by the PNGW. Finally, in step S680, a second device capabilities query response message is transmitted to the CPNS server according to a PNGW capability of the PNGW by the PNGW.

FIG. 7 is a flowchart for illustrating a method of OMA according to another embodiment of the invention. To begin, in step S710, whether a PNE capability of a PNE (Personal Network Element) or a PNGW capability of a PNGW (Personal Network Gateway) changes is checked. When the PNE capability of the PNE changes, in step S720, a first device capabilities change notification message is transmitted by the PNE. In step S730, the first device capabilities change notification message is relayed by the PNGW. In step S740, the first device capabilities change notification message is received through the PNGW by a CPNS (Converged Personal Network Service) server. Next, in step S750, a device capabilities change notification confirm message which comprises a target ID (Identification) is transmitted to the PNGW by the CPNS server, wherein the target ID indicates the PNE. Finally, in step S760, the device capabilities change notification confirm message is relayed to the PNE by the PNGW. On the other hand, when the PNGW capability of the PNGW changes, in step S770, a second device capabilities change notification message is transmitted by the PNGW. Next, in step S780, the second device capabilities change notification message is received by the CPNS server. Finally, in step S790, the device capabilities change notification confirm message which comprises a target ID is transmitted to the PNGW by the CPNS server, wherein the target ID indicates the PNGW.

In the invention, the device capabilities query request message and the device capabilities change notification message are transmitted so as to provide the knowledge of device capabilities for the CPNS Servers. With the knowledge of device capabilities, the CPNS enabler can achieve better performance in resources assignment and utilization.
