3 is a diagram illustrating a resource sharing method when a master terminal and a slave terminal are located on the same exchange, and the operation thereof will be described below.

The master terminal receiving the wireless data content inputs the number of the mobile communication terminal which wishes to simultaneously receive the corresponding wireless data content, and transmits the corresponding content sharing request signal to the content providing server connected through the wireless Internet network (S31).

At this time, the master terminal is a device that is currently receiving the wireless data content from the content providing server, and has been assigned a session and IP with the PDSN for receiving the wireless data content. When providing wireless data content, the content providing server provides a number input box on the content service screen provided to the master terminal to display the number input box so that the master terminal can input the number of the mobile communication terminal, that is, the slave terminal number in the corresponding number input box. Make sure

The content providing server receiving the content sharing request signal including the slave number from the master terminal receives the request from the home location register to determine whether the corresponding slave number is located on the same exchange as the master terminal (S32).

At this time, the content sharing request signal of the master terminal is delivered in the order of RPP and PDSN of the radio access device and the PDSN, that is, the base station and the base station controller, and finally received by the content providing server, and the content providing server receiving the request signal is a slave terminal. In order to check whether the corresponding number is located in the same exchange as the master terminal by extracting the number of the slave terminal to request the location information of the home terminal is provided.

As a result of the location information inquiry about the slave terminal from the home location register, when the slave terminal is located on the same exchange as the master terminal, the content providing server attempts to receive a slave terminal through the corresponding exchange (S33).

More specifically, the content providing server transmits an incoming request signal to the slave terminal to the exchange, and the exchange transmits the request signal to the corresponding slave terminal through the wireless access device serving the slave terminal, that is, the base station controller and the base station. do.

Thereafter, when a response to the incoming call is received from the slave terminal, the content providing server requests a session allocation to the RPP (S34). At this time, the content providing server requests that the session allocation to the slave terminal is the same as the session allocated to the master terminal, the RPP receiving the request signal requests resource allocation to the PDSN, and the PDSN connects to the master terminal according to the request signal of the RPP. Assign the same session to the slave terminal.

Through the above process, the master terminal and the slave terminal are assigned the same session to establish a connection with the PDSN.

In addition, the content providing server transmits an IP allocation request for the slave terminal to the PDSN (S35). In detail, the content providing server transmits an IP allocation request for the slave terminal to the base station controller in the radio access apparatus, and the base station controller transmits the received IP allocation request signal to the RPP. The RPP finally delivers the request signal to the PDSN, and the PDSN receiving the request signal performs an IP allocation procedure for the corresponding slave terminal.

At this time, it is to be understood that the IP requested to be allocated from the content providing server is the same as the IP already assigned to the master terminal.

By establishing a session connection with the PDSN and assigning an IP, the slave terminal is ready to receive wireless data content from the content providing server.

Thereafter, the content providing server simultaneously provides the corresponding wireless data content provided to the master terminal to the slave terminal together with the master terminal (S36).

That is, the content providing server transmits the wireless data content based on the IP. Since the master terminal and the slave terminal share the same IP and share the same, the wireless data content can be simultaneously provided to the slave terminal only by the request of the master terminal. Will be.

In this case, the provision of the wireless data contents is achieved by finally delivering the wireless data contents to the master terminal and the slave terminal through a procedure in which the corresponding wireless data contents are received in the PDSN and then in the RPP connected to the PDSN.

The resource sharing method when the master terminal and the slave terminal are located on different exchanges will now be described with reference to FIG. 4.

First, the master terminal receiving the wireless data content inputs the number of the mobile communication terminal which wishes to simultaneously receive the corresponding wireless data content, and transmits the corresponding content sharing request signal to the content providing server connected through the wireless Internet network (S41). ).

At this time, the master terminal is a device that is currently receiving the wireless data content from the content providing server, and has been assigned a session and IP with the PDSN for receiving the wireless data content. When providing wireless data content, the content providing server provides an input box on the content service screen provided to the master terminal to display the input box so that the master terminal inputs the number of the mobile communication terminal, that is, the slave terminal number, in the corresponding input box. .

The content providing server receiving the content sharing request signal including the slave number from the master terminal receives the request from the home location register to determine whether the corresponding slave number is located on the same exchange as the master terminal (S42).

In order to check whether the corresponding number is located in the same exchange as the master terminal by extracting the number of the terminal, the terminal receives location information of the slave terminal to the home location register.

As a result of the location information inquiry about the slave terminal from the home location register, when the slave terminal is located on a different exchange from the master terminal, the content providing server attempts to reach the slave terminal through the corresponding exchange to which the slave terminal belongs ( S43).

That is, the content providing server transmits the incoming request signal to the exchange in which the slave terminal is located, and transmits the incoming request signal to the slave terminal through the base station controller and the base station in which the exchange receiving the request signal serves the slave terminal.

After the incoming request, when the response for the incoming call is received from the slave terminal, the content providing server transmits a session allocation request for the slave terminal to the RPP in the switch area (S44).

When the allocation procedure according to the session allocation request is described in detail, the content providing server transmits the session allocation request to the RPP, where the RPP is a device connected to the exchange in the area where the slave terminal is located and is included in the base station controller. Upon receiving the request signal from the content providing server, the RPP requests resource allocation to the PDSN, and the PDSN allocates a session to the slave terminal according to the request signal of the RPP. At this time, the PDSN should be the same device as the PDSN that establishes a connection with the master terminal and performs data communication with the master terminal.

In addition, the content providing server transmits an IP allocation request for the slave terminal to the PDSN (S45). At this time, the IP assignment procedure receives an IP allocation request from the content providing server to the base station controller serving the slave terminal, and the base station controller receiving the IP transmission transmits the corresponding IP allocation request signal to the RPP. The RPP finally transmits the request signal to the PDSN so that the PDSN receiving the IP signal performs IP allocation to the slave terminal in response to an IP allocation request by the content providing server. Here, it should be understood that the IP assigned to the slave terminal is the same as the IP already assigned to the master terminal.

By establishing a session connection with the PDSN and assigning an IP, the slave terminal is ready to receive wireless data content from the content providing server.

Thereafter, the content providing server simultaneously provides the corresponding wireless data content provided to the master terminal to the slave terminal together with the master terminal (S46).

The content providing server transmits the wireless data content based on the IP. Since the master terminal and the slave terminal share the same IP and share the same, the wireless data content can be simultaneously provided to the slave terminal only by the request of the master terminal. In this case, the wireless data content provision is performed by the PDSN receiving the wireless data content from the content providing server and transmitting the wireless data content to the RPP, and simultaneously transmitting the corresponding wireless data content to the master terminal and the slave terminal. do.
