MODE FOR INVENTION
In a CPNS environment disclosed in the present invention, a portable terminal which can perform only near field radio communication, but cannot perform cellular communication over a mobile communication network is enabled to employ data service that can be provided through cellular communication by performing near field radio communication with a mobile communication terminal which plays the role of a PN (Personal Network) service gateway.
Hereinafter, preferred embodiments the present invention are described in more detail with reference to the accompanying drawings.
FIG. 1 is a diagram showing a connection between a system and a communication network according to according to the present invention.
The system in which a server or a mobile communication terminal performs an initialization operation in a CPNS environment and provides CPNS to an end-point terminal includes a CPNS server 100, a mobile communication terminal 200, and an end-point terminal 300. The system is chiefly divided into a first case where CPNS reservation is set only in the mobile communication terminal 200 and a second case where CPNS reservation is set both in the mobile communication terminal 200 and the CPNS server 100.
The second case corresponds to a case where CPNS reservation is set in the CPNS server 100. The second case differs from the first case in that when a scheduled time is reached, the CPNS server 100 requests the mobile communication terminal 200 to search for an end-point terminal and requests certification information from the mobile communication terminal 200.
More particularly, the CPNS server 100 performs a certification procedure for a corresponding terminal on the basis of pieces of terminal information about the mobile communication terminal 200 and the end-point terminal 300, received from the mobile communication terminal 200, requests content from the content providing server 400, and executes CPNS.
In the case where the CPNS server 100 receives a CPNS reservation request from the end-point terminal 300 via the mobile communication terminal 200 and registers the CPNS reservation, when a set time is reached, the CPNS server 100 requests the mobile communication terminal 200 to search for an end-point terminal and transmits a certification information request to the mobile communication terminal 200.
After the CPNS reservation is set by the end-point terminal 300, the mobile communication terminal 200 searches for the end-point terminal 300 when a set time is reached and requests CPNS from the CPNS server 100 by transmitting its own terminal information and the terminal information of the end-point terminal 300 to the CPNS server 100. Next, when the requested CPNS is received from the CPNS server 100, the mobile communication terminal 200 opens a CPNS session with the end-point terminal 300 and provides reserved CPNS.
The end-point terminal 300 requests the CPNS reservation from the mobile communication terminal 200 or the CPNS server 100, wakes up a relevant application in response to a command received from the mobile communication terminal 200 when the set time is reached, and then executes the CPNS received from the CPNS server 100 via the mobile communication terminal 200.
The CPNS server 100 disclosed in FIG. 1 has the mobile communication terminal 200 and the end-point terminal 300 connected thereto, and it is assumed that the CPNS server 100 previously stores pieces of terminal information (for example, an LCD size and a codec) about the end-point terminal 300.
The end-point terminal 300 disclosed in FIG. 1 refers to a portable terminal equipped with a near field radio communication function, such as a personal multimedia player (PMP), an MP3 Player, a navigator, a mobile phone, and a game machine.
Meanwhile, the near field radio communication network includes all communication networks enabling near field radio communication, such as WLAN, Bluetooth, and UWB (Ultra WideBand).
On the other hand, the CPNS server 100, the mobile communication terminal 200, and the end-point terminal 300 shown in FIG. 1 experience an initial setting process for CPNS, which is described later.
FIG. 2 is a flowchart illustrating an initial setting method for CPNS according to the present invention.
First, the end-point terminal 300 searches for a mobile communication terminal to play the role of a PN (Personal Network) Gateway Device in order to use CPNS at step S10.
Next, the end-point terminal 300 requests service from the mobile communication terminal 200 retrieved at step S10. Here, the end-point terminal also transmits information, indicating that CPNS is possible, to the mobile communication terminal 200 at step S20.
When the service request is received from the end-point terminal, the mobile communication terminal 200 checks whether the end-point terminal can use the CPNS at step S30.
If, as a result of the check at step S30, the end-point terminal can use the CPNS, the mobile communication terminal 200 transmits a certification message, indicating that the CPNS is available, to the end-point terminal 300 at step S40.
When the certification message indicating that the CPNS is available is received from the mobile communication terminal, the end-point terminal 300 transmits its own ID to the mobile communication terminal 200 at step S50.
The mobile communication terminal 300 confirms whether the format of the ID, received from the end-point terminal 200, is identical with the format of an ID issued by the CPNS at step S60. If, as a result of the confirmation, the format of the ID, received from the end-point terminal 200, is identical with the format of the ID issued by the CPNS, the mobile communication terminal 300 transmits a certification message, indicating that the service is possible, to the end-point terminal 300 at step S70.
Next, the mobile communication terminal 200 transmits its own certification information and ID and the certification information and ID of the end-point terminal 300 to the CPNS server 100 at step S80.
The CPNS server 100 determines whether the CPNS is available to the mobile communication terminal and the end-point terminal by confirming the pieces of certification information and the IDs received from the mobile communication terminal at step S90.
If, as a result of the determination, the CPNS is determined to be available to both the mobile communication terminal and the end-point terminal, the CPNS server 100 informs the end-point terminal of this fact so that the end-point terminal can perform the CPNS, including a request for content, at step S100.
If, as a result of the determination at step S90, the CPNS is determined not to be available to any one of the mobile communication terminal and the end-point terminal, the CPNS server 100 informs the end-point terminal of this fact and terminates the process.
Meanwhile, if, as a result of the check at step S30, the CPNS is not available to the end-point terminal, the mobile communication terminal 200 transmits a message, indicating that the service is not available, to the end-point terminal 300 and then terminates the process.
On the other hand, if, as a result of the confirmation at step S60, the format of the ID, received from the end-point terminal 200, is not identical with the format of the ID issued by the CPNS, the mobile communication terminal 300 transmits a message, indicating that the service is not available, to the end-point terminal 300 and then terminates the process.
FIG. 3 is a diagram showing the configuration of the CPNS server according to the present invention.
As shown, the CPNS server 100 includes a communication interface unit 110, a mobile communication terminal information management unit 120, an end-point terminal information management unit 130, a reservation information registration unit 140, a certification processing unit 150, a content request and reception unit 160, a service providing unit 170, and a database 180.
More particularly, the communication interface unit 110 is an element for performing communication over a mobile communication network.
The mobile communication terminal information management unit 120 registers information about the mobile communication terminal 200, performing communication with the end-point terminal 300 over a near field radio communication network, with the database 180 and manages the registered information.
The end-point terminal information management unit 130 registers information about the end-point terminal 300, transmitting and receiving information to and from the mobile communication terminal 200 over a near field radio communication network, with the database 180 and manages the registered information.
In the case where CPNS reservation is set in the CPNS server 100, the reservation information registration unit 140 receives a CPNS reservation request from the end-point terminal 300 via the mobile communication terminal 200 and sets CPNS reservation on the basis of the CPNS reservation request.
In the case where the CPNS reservation is registered with only the mobile communication terminal 200 not the reservation information registration unit 140 of the CPNS server 100, It is preferred that the reservation information registration unit 140 be omitted from the CPNS server 100.
The certification processing unit 150 performs a certification procedure on the basis of pieces of terminal information about the mobile communication terminal 200 and the end-point terminal 300 received from the mobile communication terminal 200.
In the case where CPNS reservation is registered with the CPNS server 100, when a scheduled set time is reached, the certification processing unit 150 requests a search for the end-point terminal 300 and certification information from the mobile communication terminal 200.
The content request and reception unit 160 requests reserved content from the content providing server 400 and receives the reserved content from the content providing server 400.

More particularly, the wireless communication unit 210 is an element for performing communication over a mobile communication network or a near field radio communication network.
When a CPNS reservation request is received from the end-point terminal 300, the reservation information registration unit 250 registers CPNS reservation on the basis of the CPNS reservation request.
When a scheduled set time is reached, the end-point terminal search unit 260 searches for the end-point terminal which has requested the CPNS reservation.
In the case where the CPNS reservation is set in the CPNS server 100, when a request for a search for the end-point terminal 300 and for certification information is received from the CPNS server 100, the end-point terminal search unit 260 searches for the end-point terminal 300.
The certification information processing unit 270 requests certification and CPNS from the CPNS server 100 by transmitting its own terminal information and pieces of terminal information of the end-point terminal 300 retrieved by the end-point terminal search unit 260.
When the CPNS server 100 provides CPNS, the session processing unit 280 opens a CPNS session with the end-point terminal 300 to which the reserved CPNS will be provided.
The service providing unit 290 provides the end-point terminal 300 with the reserved CPNS received from the CPNS server 100.

The application driving unit 360 wakes up a pertinent application in order to provide the specific CPNS in response to a command received from the mobile communication terminal 200.
The content request and reception unit 370 performs near field radio communication with the mobile communication terminal 200 and requests content, requested by the user, from the mobile communication terminal 200.
FIG. 6 is a flowchart illustrating an example of a method of providing CPNS to the end-point terminal in a CPNS environment according to the present invention. A case where CPNS reservation is set in the mobile communication terminal 200 is described as an example.
First, the mobile communication terminal 200 receives a CPNS reservation request from the end-point terminal 300 and registers the CPNS reservation request at step S101.
When a scheduled set time is reached, the mobile communication terminal 200 searches for the end-point terminal 300 which has requested the CPNS reservation at step S103.
Next, when pieces of terminal information about the end-point terminal 300 retrieved at step S103 are received at step S105, the mobile communication terminal 200 requests certification and CPNS from the CPNS server 100 by transmitting its own terminal information and the terminal information of the end-point terminal 300 at step S107.
The CPNS server 100 performs a certification procedure on the basis of the information received from the mobile communication terminal 200, requests content, corresponding to reserved content, from the content providing server 400 at step S109, receives the requested content from the content providing server 400 at step S111, and transmits the received content to the mobile communication terminal 200 at step S113.
When the CPNS server provides the CPNS, the mobile communication terminal 200 opens a CPNS session with the end-point terminal 300 in order to provide the reserved CPNS to the end-point terminal 300 at step S115.
The end-point terminal 300 wakes up relevant application in response to a command received from the mobile communication terminal 200 at step S117 and executes the CPNS information received from the mobile communication terminal 200 at step S119.
