1 is an exemplary configuration diagram of a system interworking heterogeneous communication networks for a packet service to which the present invention is applied. In the drawing, "11" is a mobile terminal, "12" is a terminal, and "13" is a wireless communication network (preferably IMT-2000 network), "14" denotes Internet, and "30" denotes a mobility processor.

In this embodiment, the current wireless subscriber network (WLL), broadband wireless subscriber network (B-WLL), radio frequency network (TRS), mobile telephone network (Cellullar), personal mobile communication network (PCS), intelligent transportation network (ITS), Heterogeneous communication networks in which the wireless communication network 13 and the Internet 14 interoperate, including other mobile telephone networks in foreign countries, next-generation mobile communication networks such as IMT-2000 and UMTS, which are currently being standardized in the European and North American methods. In order to process the packet service provided by the Internet 14 under the environment, a mobility processing scheme in a wireless communication network, particularly an IMT-2000 network, is assumed.

When requesting various Internet information (packet service processing) from the mobile terminal 11 to the IMT-2000 network 13 (101), the IMT-2000 network 13 receives a packet service processing request to the Internet (14). The packet service processing request is transmitted (102).

Thereafter, desired information is extracted from the Internet 14 and the packet service processing result thereof is transmitted to the mobile terminal 11 via the IMT-2000 network 13 (103, 105). At this time, when delivering the packet service processing result to the mobile terminal 11, in order to ensure the mobility of the mobile terminal 11, the mobility processing device 30 in the IMT-2000 network 13 performs a mobility processing function for the packet service. Perform 104.

The mobility processing device 30 is the most effective device for solving the economic benefits and convenience of subscribers by effectively processing packet services using the Internet 14 in the IMT-2000 network 13.

The mobility processing device 30 for packet service processes packet service processing requests presented online between the terminal 12 and the IMT-2000 (13) network elements as quickly as possible to minimize the effect on the service. It should have performance and satisfy various service processing needs of subscriber. In addition, it should be extensible so that it can be applied well when system expansion and roaming with other service providers are allowed.

The mobility processing apparatus 30 for a packet service according to the present invention uses the mobile terminal 11 to process various packet services using the Internet 14 as well as to change a user's own IP address on the Internet 14. By supplementing the limitations of the mobility support problem in which transparent transmission of time data cannot be guaranteed, it is possible to maximize the use efficiency of packet services using the Internet and to guarantee the mobility of subscribers who use the Internet information in a wireless mobile communication network.

In the present invention, the wireless network that guarantees the mobility of the user through the mobility processor 30 that can guarantee the transparent delivery of the packet service using the Internet without changing the IP address of the subscriber in the IMT-2000 network 13 Internet service can be provided. In addition, it is possible to establish a scalable mobile communication network even in networks with different communication protocols for roaming between providers.

2A and 2B are flowcharts illustrating an embodiment of a mobility processing method for a packet service according to the present invention, which is a processing procedure that participates in the mobility processing function 104 of FIG. 3 shows a processing procedure associated with the packet service processing unit 32 and the packet service connection unit 33 in FIG.

As shown in FIGS. 2A and 2B, in the mobility processing method for a packet service, the terminal 12 such as the mobile terminal 11 and the notebook computer first informs the IMT-2000 network 13 of the IP information allocated thereto. In step 201, an IP initial registration request is transmitted to the packet service processor 32 in the mobility processor 30 for the packet service proposed.

Thereafter, the packet service processor 32 transmits an IP initial registration request to the packet service connection unit 33 that manages information of all terminals (202). At this time, the IP initial registration request becomes actual home IP information.

Next, the packet service connection unit 33 retrieves the registration information and authenticates whether the subscriber is an acceptable subscriber. If the subscriber is a legitimate subscriber, the packet service connection unit 33 registers in the subscriber database composed of a mapping table between the home IP address and the temporary IP address in the packet service connection unit 33. (203), the home IP registration result message is transmitted to the packet service processor 32 (204).

Subsequently, the packet service processing unit 32 interprets the home IP registration result message and stores the data in the subscriber database for temporary IP address storage in the packet service processing unit 32 if the registration is possible (205), and then moves the home IP registration result. The terminal 11 transmits the data to the terminal 11 (206).

If the authentication result at the packet service connection unit 33 is not a legitimate subscriber, the packet service connection unit 33 does not perform the registration function and transmits the contents of the home IP registration result message to the packet service processor 32 without registering. The lower surface 204, the packet service processing unit 32 transmits to the mobile terminal 11 the contents of the registration not allowed in the home IP registration result message without storing in the database (206). In this case, the packet service processing request and the result can be transmitted continuously with the registered IP information. That is, when the mobile terminal 11 has the home IP information and transmits the packet service processing request to the packet service processing unit 32 (207), the packet service processing unit 32 sends the received packet service processing request message to the packet service connection unit. Send to 33 (208).

Thereafter, the packet service connection unit 33 extracts information from the Internet 14 (209) and transmits the packet service processing result message configured with the extracted information and the requested home IP address to the packet service processing unit 32 (210). . Thereafter, the packet service processor 32 extracts home IP information from the received packet service processing result message and transmits the packet service processing result message of the extracted information to the mobile terminal 11 of the corresponding IP information (211). At this time, when the mobile terminal 11 is moved and the IP of the terminal is changed (212), the mobile terminal 11 transmits the IP to the packet service processor 32 to inform the IMT-2000 network 13 of the changed IP information. The registration request is sent (213).

Next, the packet service processing unit 32 transmits an IP registration request to the packet service connection unit 33 which manages information of all terminals (214). At this time, the IP change registration request becomes temporary IP information about actual home IP information.

Subsequently, the packet service connection unit 33 receiving the IP registration request from the packet service processing unit 32 retrieves the registration information and authenticates whether the subscriber is an acceptable subscriber. If the subscriber is a legitimate subscriber, the home IP address and temporary address in the packet service connection unit 33 are obtained. After allocating and storing the temporary IP address for the home IP address registered first in the subscriber database including the mapping table between the IP addresses (215), the temporary IP registration result message is transmitted to the packet service processor 32 (216).

Subsequently, the packet service processing unit 32 interprets the temporary IP registration result message and stores it in the subscriber database for storing the temporary IP address in the packet service processing unit 32 if it can be registered (217). Is transmitted to the mobile terminal 11 (218).

If the authentication result at the packet service connection unit 33 is not a legitimate subscriber, the packet service connection unit 33 does not perform a registration function and transmits to the packet service processing unit 32 the content of the registration that is not registered in the temporary IP registration result message. In operation 216, the packet service processor 32 transmits the contents of the non-registration to the temporary IP registration result message to the mobile terminal without storing them in the database (218). In this case, the packet service processing request and result are sent in the temporary IP information mapped to the home IP. Therefore, even if the mobile terminal 11 moves and the IP of the terminal changes, it is possible to assign a temporary IP every time the home IP is registered. That is, when the mobile terminal 11 transmits the packet service processing request to the packet service processing unit 32 with the temporary IP information registered for each movement (219), the packet service processing unit 32 sends the received packet service processing request message. The packet service is transmitted to the connection unit 33 (220).

Next, the packet service connection unit 33 extracts information from the Internet 14 (221) and tunnels and transmits the packet service processing result message configured with the extracted information and the requested temporary IP address to the packet service processing unit 32 ( 222,223). Thereafter, the packet service processing unit 32 extracts the temporary IP information from the received packet service processing result message and tunnels and transmits the packet service processing result message of the extracted information to the mobile terminal 11 of the corresponding IP information (224). . In this case, i.e., when the mobile terminal 11 uses the changed IP information every time the mobile terminal 11 changes the service request status, the binding state of the service capable of receiving the service with the temporary IP address interpreted as the same meaning as the home IP information registered first. (225).

On the other hand, when the mobile terminal 11 moves the area to which the temporary IP address is assigned, the packet service processing unit 32 sends a temporary IP registration request message to cancel the assigned temporary IP address and register the IP address in the new area. (226), the packet service processing unit 32 transmits a temporary IP registration request to the packet service connection unit 33 which manages the information of all terminals (227). At this time, the packet service access unit 33 cancels the temporary IP address registered in the subscriber database composed of the mapping table between the home IP address and the temporary IP address (228), and sends a temporary IP registration cancellation result message to the packet service processing unit 32. (229).

Thereafter, the packet service processor 32 receiving the temporary IP registration termination result message from the packet service access unit 33 releases the temporary IP address from the subscriber database for storing the temporary IP address (230), and then terminates the temporary IP registration. The result is transmitted to the mobile terminal (231). Accordingly, the service is released from the binding where the relationship between the home IP address and the temporary IP address is destroyed (232). For this reason, even if the mobile terminal 11 continues to move (even if the IP information of the terminal changes), the service processing can be performed regardless of the IP change of the terminal in the service binding state.
