Abstract

PURPOSE: A data termination service method for mobile terminals in a mobile network is provided to terminate the originating packet data from an arbitrary data terminal, such as a personal computer, etc. CONSTITUTION: If a mobile terminal transmits a data termination service request message to a data service access node, the transmitted message is received to the data service access node through the medium of an access network(S301). Based on the data termination service request message, the data service access node allocates a dynamic IP address for the mobile terminal(S302) and transmits a data termination service admission message to the mobile terminal so that the mobile terminal can recognize that data termination service has been allowed(S303,S304). Then the data service access node transmits a registration request message for the allocated dynamic IP address to a DNS(Domain Name System) server(S305). The DNS server connects and registers a specific ID, or the destination number of the mobile terminal, and the allocated dynamic IP address(S306), and transmits a response message to inform the data service access node that the registration of the dynamic IP address has been completed(S307). If a data terminal transmits a request message for the dynamic IP address to the DNS server through the Internet(S308), the DNS server recognizes that the dynamic IP address of the mobile terminal having the specific ID as its destination number has been requested, based on the received message. Accordingly the DNS server provides the dynamic IP address information allocated to the mobile terminal to the data terminal(S309).

In the fourth step, when the data transmitted from the data terminal is received, a data communication call is established with the mobile terminal via the mobile communication network, and then the received data is transmitted or the mobile communication network is mediated. The received data is transmitted to the mobile terminal using a short message service scheme.

Hereinafter, a data service receiving method of a mobile terminal through a mobile communication network according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 2 is a block diagram of a mobile communication network according to the present invention, in which a DNS server 20 such as a domain name system (DNS), for example, compares the configuration of the existing mobile communication network of FIG. An additional data terminal 21, such as a personal computer, for example, which is further connected between 14 and the Internet network 15, and connected to the Internet network 15, is shown for the purpose of explanation below. Since all are the same as in FIG.

3 is a flowchart of a method of receiving a data service of a mobile terminal through a mobile communication network according to an embodiment of the present invention. Since it is implemented in the mobile communication network of FIG. 2, it will be described in parallel with the operation thereof. (11) and the base station controller 12 and the exchange 13 is expressed as an access network, the DNS server 20 has a specific domain name, under the domain name of the mobile terminal 10 In addition, it is assumed that a plurality of subscriber address accounts having IDs of specific information (for example, called phone numbers) of the mobile terminals are listed in association with the subscriber mobile terminals. For example, when the incoming call number of the mobile terminal 10 is '123-XXXX' and the domain name of the DNS server 20 is 'SKTIMT2000.COM', the DNS server 20 may include the mobile terminal 10. In the following description, a method of receiving data of a mobile terminal through a mobile communication network according to an embodiment of the present invention will be described on the premise that an address account associated with the above) is registered as '123-XXXX.SKTIMT2000.COM'.

First, when the mobile terminal 10 transmits a data incoming service request message to the data service access node 14, the transmission message is received by the data service access node 14 via the access network (S301). ), The data service access node 14 allocates a dynamic IP address for the mobile terminal 10 based on the received data incoming service request message (S302), and also receives data to the mobile terminal 10 side. By transmitting a service acceptance message (S303), the mobile terminal 10 to recognize that the data incoming service has been accepted (S304).

Subsequently, the packet data access node 14 transmits a registration request message for the dynamic IP address assigned to the mobile terminal 10 to the DNS server 20 (S305), and the DNS server 20 Based on the received registration request message, the specific ID belonging to the domain name of the address account listed in association with the mobile terminal 10 and the allocated dynamic IP address are mutually associated with each other. For example, it is assumed that the incoming phone number of the mobile terminal 10 is '123-XXXX' and the corresponding address account is '123-XXXX.SKTIMT2000.COM'. After registering a specific ID number '123-XXXX' and the allocated dynamic IP address in association with each other (S306), a response message for completing the registration of the dynamic IP address is transmitted to the data service access node (1). 4) (S307).

Next, the data terminal 21 transmits a request message for the corresponding dynamic IP address to the DNS server 20 through the Internet network 15 based on the address of '123-XXXX.SKTIMT2000.COM'. In case (S308), the DNS server 20 recognizes a request for a dynamic IP address of the mobile terminal 10 having a specific ID of '123-XXXX' as a called number based on the received message, and moves the Dynamic IP address information currently assigned to the terminal 10 is provided to the data terminal 21 (S309).

Next, when the data terminal 21 transmits the desired data to the mobile terminal 10 based on the provided dynamic IP address, the transmitted data is sent to the Internet network 15 based on the dynamic IP address. The data service access node 14 is received (S310), and the data service access node 14 calls the mobile terminal 10 via the access network to notify that new data is received (S311). When the mobile terminal 10 recognizes whether the new data has been received and responds to the call (S312), the data service access node 14 moves the mobile network through the access network. The received data is transmitted to the terminal 10 to be received (S313).

On the other hand, when new data is received in the data service access node 14 as in step S310, steps S311 to S313 for establishing a data communication path so that the mobile terminal 10 can receive data. In addition to the method, when the size of the data is small, the data may be delivered to the mobile terminal 10 from the data service access node 14 through the access network in the conventional short message service method. That is, if the data can be received only from the data terminal 21 to the data service access node 14 by performing the steps S301-S310, the mobile terminal 10 can receive the corresponding data through the access network. There are many ways to implement this.

FIG. 4 is an example of a method of deactivating a data terminating service activated according to the present invention of FIG. 3. First, when the mobile terminal 10 transmits a data terminating service release request message to the data service access node 14 side. The transmission message is received by the data service access node 14 via the access network (S401), and the data service access node 14 performs the mobile terminal on the basis of the received data terminating service release request message. In addition to releasing the corresponding dynamic IP address assigned to (10) (S402) and transmitting a data terminating service release acceptance message to the mobile terminal 10 side (S403), the mobile terminal 10 receives a data terminating service. Recognize that the release (S404).

Subsequently, the packet data access node 14 transmits a registration deletion request message for the corresponding dynamic IP address that has been deallocated with respect to the mobile terminal 10 to the DNS server 20 (S405). 20) after deleting the corresponding aggressive IP address which was registered in step S306 of FIG. 3 based on the received registration deletion request message (S406), and finally responding to the response message for the completion of the dynamic IP address deletion. It transmits to the data service access node 14 to terminate the data incoming service deactivation process (S407).

As such, when the data receiving service is deactivated, the DNS server 20 receives the request message of the dynamic IP address from the data terminal 21 (S408), and the dynamic IP address is not registered or deleted after registration. The data terminal 21 informs that the incoming service is in an inactive state (S409).

As described in detail above, according to the method of receiving a data service of a mobile terminal through a mobile communication network according to the present invention, a DNS server for interworking and registering a specific ID of a mobile terminal and an IP address dynamically allocated to the mobile terminal is moved. By establishing in a communication network, the data terminal as a counterpart node connected to the Internet network can obtain a dynamic IP address currently assigned with a specific ID of the mobile terminal, thereby enabling the mobile terminal to receive data. Create.
