The MAC layer is a layer that physically communicates with the AP 410 layer of the service network 400. The second IP layer is a layer that manages and controls an IP address allocated from the AP 410 to perform IP communication with the AP 410 layer. The TCP / UDP layer is a layer for managing and controlling a protocol, i.e., a protocol of information transmitted and received based on the IP. The TCP / UDP layer of the second communication interface 202 may perform communication channel formation and information transmission and reception under the control of the application layer of the first communication interface 201.

The service network 400 is disposed between the AP 410 communicating with the second terminal 200 and the AP 410 and the server 300 to allocate an IP to the second terminal 200. The packet data gateway (PDG) 420 is included. The AP 410 and the PDG 420 may perform communication via wired or wireless.

The AP 410 may form a wireless interface with the second terminal 200, and may form a wired interface with the PDG 420. The AP 410 allocates a second IP to the second terminal 200. The second IP may be used in communication between the second terminal 200, the AP 410, and the PDG 420. To this end, the AP 410 allocates a second IP for limited IP-based communication between the second terminal 200 and a MAC layer for physically establishing a wireless communication, for example, a WLAN connection.

Information transmission of the service network system of the present invention having each layer as described above will be described. First, when the second terminal 200 accesses the first terminal 100 and then attempts to access the server 300 through the AP 410 and the PDG 420, the PDG 420 A first IP address is assigned to the second terminal 200. Here, the PDG 420 alarms the first IP address to the AP 410 and the server 300, respectively. The AP 410 allocates a second IP to the second terminal 200 to support IP-based information transmission between the second terminal 200 and the PDG 420 and assigns the allocated second IP. The PDG 420 alarms. Thereafter, the information generated by the server 300 is packed based on the first IP in the PDG 420, and then packed based on the second IP and then delivered to the AP 410. The second AP 410 distinguishes the second terminal 200 by using the first IP and the second IP, and transfers the packed information to the second terminal 200. The second terminal 200 unpacks the packed information, and determines whether to deliver the packed information to the first terminal 100 with reference to the first IP address. That is, when the first terminal 100 is processing a service based on the first IP address, the second terminal 200 is the first IP address and the first terminal 100 of the received information. ) Transmits data having port information used by the first terminal to the first terminal 100. In this case, when the first terminal 100 and the second terminal 200 want to process a service corresponding to the same IP address and the same port information, the first terminal 100 and the second terminal 200. The port manager performs port management by changing the port or terminating the program. This will be described in more detail with reference to FIG. 3.

3 is a diagram illustrating in more detail a hierarchy of a first terminal 100 and a second terminal 200 according to an embodiment of the present invention that performs port management.

Prior to the description, since each layer between the first terminal 100 and the second terminal 200 of the present invention has the same configuration as the layer described in FIG. 2 except for the port manager layer, except for the port manager layer Duplicate detailed description of the configuration will be omitted.

Referring to FIG. 3, the first terminal 100 and the second terminal 200 of the present invention include a port manager layer between the TCP / UDP layer and the first IP layer as described above. The port manager layer may be logically included in the TCP / UDP layer and may also be included in the IP layer. The port manager layer transmits and receives port information of the first terminal 100 and the second terminal 200 to each other, and manages ports set in each terminal based on the information.

For example, it is assumed that the first terminal 100 uses a first service having first port information and a first IP address. In this case, when the second terminal 200 wants to access the server 300 to perform a first service having the first port information and the first IP address, the first port manager layer is configured to the second terminal. Information about the first service to be performed by the 200, that is, the first port information and the first IP address, is transmitted to the first terminal 100. Accordingly, the first terminal 100 may conflict with the first port information and the first IP address of the first service among the services currently performed by the first terminal 100 through the port manager. Forward to the second port manager layer. Correspondingly, the second terminal 200 performs an alarm regarding the port information collision, and changes the port information or terminates the program accordingly. This will be described in more detail with reference to FIG. 4.

4 is a block diagram schematically illustrating a detailed configuration of a port manager of a first terminal 100 and a port manager of a second terminal 200 according to an embodiment of the present invention.

In the following description, since the first port manager 165 of the first terminal 100 and the second port manager 265 of the second terminal 200 may include the same configuration, the first port manager ( Each of the configurations of 165 and the second port manager 265 will be described in an integrated manner.

Referring to FIG. 4, the first port manager 165 of the present invention includes a first alarm unit 163, a first alternative port search / apply unit 167, a first priority control unit 169, and a first interface. The second port manager 265 may include a second alarm unit 263, a second alternative port search / apply unit 267, a second priority control unit 269, and a second interface. It is comprised including the part 261.

The first and second alarm units 163 and 263 alarm a collision of the selected port according to activation of a specific application program. For example, it is assumed that the first terminal 100 uses the first IP address and the first port information according to the use of the first service. In this case, when the second terminal 200 intends to use the first IP address and the first port information according to the use of the first service, the second terminal 200 transmits the information through the second interface unit 261. Information, that is, the first IP address and the first port information is transmitted to the first terminal 100. Correspondingly, the first terminal 100 indicates that the first IP address and the first port information transmitted from the second terminal 200 collide with address information of the first service currently used by the first terminal. Transfer to the second alarm unit 263 of the second terminal 200. The second alarm unit 263 alarms that port information collides with the second terminal 200 using a popup. The first and second alarm units 163 and 263 preferably alert the collision to a terminal that is currently activated. That is, while the first terminal 100 uses the first service using the first IP address and the first port information, the user wants to use the first service using the second terminal 200. In this case, the second alarm unit 263 of the second terminal 200 may alarm information related to the collision to the second terminal 200. In the same way, when the service conversion to the first terminal 100 occurs during the activation of the second terminal 200, the first alarm unit 163 of the first terminal 100 is associated with the collision and service change You can alarm the information. In addition, when the first alarm unit 163 and the second alarm unit 263 use an alternative port, the first alarm unit 163 and the second alarm unit 263 may alarm a collision occurrence and a service support using the alternative port by using a popup message or the like.

If the first and second alternative port search / applying units 167 and 267 provide a service in which collision occurs between the first terminal 100 and the second terminal 200, whether an alternative port is possible? Do a search. The first and second alternative port searching / applying units 167 and 267 support to provide a service by switching a requested service port to an alternative port when an alternative port is available. For example, if the first terminal 100 is receiving the first service using the first IP address and the first port information, the second terminal 200 provides the same service as the first service. When requested, the second alternative port search / application unit 267 of the second terminal 200 receives information about the collision between the IP address and the port information from the second alarm unit 263. Accordingly, the second alternate port search / apply unit 267 checks whether a port to which the first service can be provided can be replaced, and if so, replaces the first service with a first IP address and an alternate port. Control to be provided to the second terminal 200 based on the second port information. Such a function can be realized based on a characteristic of providing a range of port information in a service policy when providing a service that can be used by the first terminal 100 and the second terminal 200.

The first and second priority controllers 169 and 269 control to forcibly terminate the currently provided service or the requested service according to the priority of the terminal. For example, when the first terminal 100 has a higher priority than the second terminal 200 and the first terminal 100 uses the first service, the second terminal When the 200 wants to use the first service, the second priority control unit 269 of the second terminal 200 alarms a collision between the IP address information and the port information, and the second terminal 200. Rejects the first service request. In another example, when the first terminal 100 has a higher priority than the second terminal 200, and the second terminal 200 is in a first service use situation, the first terminal 100 is used. If the first service wants to use, the first priority control unit 169 forcibly terminates the first service of the second terminal 200, so that the first terminal 100 can use the first service. Control channel formation and data reception. In this case, the first and second alarm units 163 and 263 may perform an alarm for the collision and an alarm for terminating the first service of the second terminal 200, respectively. Priorities of the first terminal 100 and the second terminal 200 may be changed according to a user or designer setting.

The first and second interface units 261 may include the first and second alarm units 163 and 263, the first and second alternative port search / apply units 167 and 267, and the first and second units described above. In order to perform each operation of the priority control units 169 and 269, it is responsible for signal transmission and reception. That is, the first and second interface unit 261 may include information about the current service state of the first terminal 100 and the second terminal 200, information of a requested signal, a collision alarm signal for the requested signal, Send and receive a program forced stop control signal, priority confirmation signal, and the like.

In this case, the audio signal according to the activation of the application program is processed by the first audio processor 120. To this end, the first audio processor 120 may include a speaker SPK, and may further include a microphone for collecting audio and transmitting the audio to the first controller 160 as necessary. In more detail, the user of the first terminal 100 generates a key input signal for activating a specific application program using the first key input unit 110. The first key input unit 110 transmits the key input signal to the first control unit 160. The first controller 160 reads and loads the corresponding application program corresponding to the key input signal from the first memory 130 and activates the application program. In this case, when the application program is a first service that needs to access the service network 400, the first controller 160 may provide first IP address information and first port information for providing the first service to the first port. Transfer to the second terminal 200 through the manager (165). On the other hand, the first control unit 160 accesses the service network 400 and the server 300 by using the second terminal 200 as a modem, and the first IP address and the first assigned in the connection process. The first service may be provided based on the port information.

Meanwhile, the first terminal 100 transmits address information of the first service, that is, first IP address and first port information, to the second terminal 200 using the first port manager 165. The maintenance and termination of the first service is controlled according to the activation of the second terminal 200. In more detail, when the second terminal 200 generates a key input signal for requesting the same service as the first service, the first port manager 165 prioritizes the first terminal 100. The rank or activation state is checked to determine whether to maintain or terminate the first service in the first terminal 100. That is, when the first terminal 100 has a higher priority than the second terminal 200, the first port manager 165 provides a service when a first service request of the second terminal 200 occurs. A signal may be transmitted to the second terminal 200 to alarm a message corresponding to the impossible. In addition, the first port manager 165 responds to the first service request from the first key input unit 110 of the first terminal 100 when the second terminal 200 is using the first service. When a corresponding signal is generated, a signal for terminating the first service of the second terminal 200 is transmitted to the second terminal 200. The first port manager 165 controls the first terminal 100 to activate the first service. The first port manager 165 uses the first service when the second terminal 200 uses the first service and generates a key input signal corresponding to the first service request from the first key input unit 110. 1 It is determined whether the alternative port support for service provision is possible, and when the alternative port support is possible, the first terminal 100 controls to activate the first service through the alternative port.

The first memory 130 may store various information for supporting the first port manager 165. For example, the first memory 130 may include IP address information and port information of a service activated in the first terminal 100 and an IP address of a service being activated or scheduled to be activated in the second terminal 200. Information and port information can be stored. The first memory 130 may also store information on an alternative port that can substitute a port of a specific service. The first memory 130 may store a first port manager 165 for collision prevention and collision prevention processing with the second terminal 200.

Hereinafter, a port management method of the user terminal will be described based on the port management apparatus of the user terminal described above.

7 is a flowchart illustrating a port management method of a user terminal according to an exemplary embodiment of the present invention.

Referring to FIG. 7, in the method for managing a port of the user terminal of the present invention, first, in operation S1101, the second terminal 200 is connected to the first terminal 100 as a modem, and the server 300 is based on this. ) Is connected. If this is described based on the first terminal 100, the first terminal 100 connects the second terminal 200 to use the second terminal 200 as a modem. Accordingly, the second terminal 200 accesses the service network 400 and receives a first IP address and a second IP address. When the first IP address is based on a wireless local area network (WLAN), the first IP address is assigned by a packet data gateway (PDG), and the second IP address is assigned by an access point (AP). The first IP address transmits data of the first terminal 100 and the second terminal 200 to the server 300, and transmits data from the server 300 to the first terminal 100 and the first IP address. It may be used when transmitting to the second terminal 200. The second IP address may be used for transferring data of the second terminal 200 to the PDG and transferring data from the PDG to the second terminal 200. The above-described IP structure is a description of the WLAN-based case, and if the service network supports another system, it may be changed according to the policy of the corresponding system. As a result, the first terminal 100 may receive the first service from the server 300 using the second terminal 200. The second terminal 200 may be connected to the server 300 to receive a second service according to a user request.

Next, in step S103, whether the first terminal 100 using the first service from the server 300 and the second terminal 200 using the second service from the server 300 have the same IP address. Check. That is, the first port manager 165 transmits the IP address and port information according to the first service to the second terminal 200, and the second terminal 200 transmits the IP address and port according to the use of the second service. Information may be transmitted to the first terminal 100. At least one of the first terminal 100 and the second terminal 200 confirms whether IP address information of the first service and the second service are the same. In step S103, when the same IP is not used, the first terminal 100 and the second terminal 200 may determine to use different services through different IP addresses. Accordingly, in operation S105, the first terminal 100 and the second terminal 200 activate a corresponding program according to each service to perform a service.

Meanwhile, in step S103, when the first terminal 100 and the second terminal 200 use the same IP, at least one of the first terminal 100 and the second terminal 200 is determined in step S107. It is checked whether the first service and the second service use the same port. In step S107, when the first terminal 100 and the second terminal 200 do not use the same port, the terminal branches to step S105 to perform a corresponding service. However, in step S107, when the same port is used, at least one of the first terminal 100 and the second terminal 200 determines that the first service and the second service have requested the same service, and in step S109 While alerting for collisions, it scans for service support through alternate ports. The alarm process may be performed only on the first terminal 100 and the second terminal 200 or any one terminal. For example, when the first terminal 100 generates the key input signal according to the use of the second service of the second terminal 200 while the first service is in use, the alarm is generated only in the second terminal 200. Pop-up messages such as "port information conflict has occurred" can be generated and displayed. In addition, the alarm process may perform a message display and an audio alarm corresponding to the alarm on both the first terminal 100 and the second terminal 200.

Next, on the basis of the information retrieved in step S109, in step S111, the first terminal 100 and the second terminal 200 determines whether the alternative port is available. This determination is preferably performed by the second terminal 200 performing the second service request while providing the first service. Hereinafter, an example of using an alternative port as a reference for the second terminal 200 will be described. In step S111, when an alternative port for the second service is possible, the second terminal 200 negotiates with the server 300 to use the second service as an alternative port in step S113. Referring to the use of the alternative port, when the second service 200 is expected to collide with the first service, the second terminal 200 sends a message for requesting the alternative port of the second service to the server 300. The server 300 may provide the second service to the second terminal 200 using an alternative port according to a message from the second terminal 200.

On the other hand, in step S111, if there is no alternative port, the first terminal 100 and the second terminal 200 checks the priority in step S115 to determine which terminal has a higher priority. Thereafter, the first terminal 100 and the second terminal 200 negotiate with each other in step S117 so that the terminal having higher priority can use the corresponding service according to the determination result, and activate the program of the terminal.

Referring to the port management method of the user terminal of the present invention described above with reference to the second terminal 200, first, while the first terminal 100 uses the first service, the second terminal 200 provides a second service; When generating a signal for requesting use, the second terminal 200 performs an alarm process according to a collision between IP addresses and port information of the first service and the second service as described above. The second terminal 200 negotiates with the server 300 whether it is possible to allow an alternative port that can replace the port information of the second service. When the second terminal 200 cannot use the alternative port, the second terminal 200 notifies the first terminal 100 of this, and terminates the first service in use by the first terminal 100. ) The second terminal 200 receives and activates information corresponding to the second service from the server 300.

As explained above. The port management method of the user terminal of the present invention can alarm, prevent, and handle port conflicts that may occur when the first terminal 100 and the second terminal 200 use the same IP address and the same port.

Meanwhile, in the above description, the port manager is provided in both the first terminal 100 and the second terminal 200, but the port manager is installed in only one terminal, and the information is transmitted and received through an interface between the terminals. The port collision of the present invention described above can also be prevented. That is, the first terminal 100 is provided with a port manager, and after checking the port information change of the second terminal 200, when using a service having the same IP and the same port, the collision alarm, prevention and processing as described above You can also carry out the process.

As described above, in the detailed description of the present invention has been described with respect to specific embodiments, various modifications are possible without departing from the scope of the invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined not only by the claims below, but also by the equivalents of the claims.
