According to an example, a mobile positioning system (MPS) 140 interworking with the service providing server 120 is optionally configured (described in detail below), and the service providing server 120 is connected through a wired Internet. There is a need for a personal computer 150 connected to and capable of data communication for implementing the method of the present invention.

The mobile terminal 110 basically has a mobile communication function, supports a wireless Internet protocol such as WAP, and user a system parameter message received from a mobile communication network in real time. (Or referred to as a subscriber) has a function of notifying the service providing server 120 through the transmission network 130 by comparing the comparison result with the base station parameters of a specific area.

The service providing server 120 serves as a server for wired / wireless internet protocols and enables searching of various contents, and specifies a mobile communication network corresponding to a specific region based on specific region information selected by a subscriber. A specific message (eg, system parameter message) sent from the mobile communication system in order to define a service area and allow the mobile terminal in an idle state to access the mobile communication system of the defined service area. ) Is obtained and provided to the subscriber's mobile terminal 110.

That is, the server providing server 120 includes a database storing specific parameters of the specific message corresponding to local information (for example, a local address such as '00 00 Seoul ') in the form of a table, and the database. To obtain specific parameters of a specific message corresponding to specific local information based on, or as another example, to specify a specific message corresponding to specific local information by linking with the mobile positioning system 140 having the database as described above. Allows the acquisition of parameters.

The transmission network 130 is composed of a complex network in which a wireless network, an IP backbone network, and an internet network for mobile communication interoperate with each other, and apply a wired / wireless internet protocol to a web (WEB) service and In addition to providing a WAP service, as well as providing a callback URL or a WAP PUSH service, it is defined as an existing known network.

The personal computer 150 has a function of accessing the service providing server 120 through the transmission network 130 and selecting the specific region by selecting the specific region. The designation of the specific region is another example. It may be performed according to a swap service method through the mobile terminal 110.

FIG. 2 is a flowchart illustrating a registration method for a specific region that a subscriber wants to be serviced in a method for determining a terminal location in a wireless Internet network according to an embodiment of the present invention. Let's explain.

First, the subscriber accesses the server providing server 120 through the transmission network 130 through a swap communication method using his mobile terminal 110 or a web communication method using a personal computer 150, and then To select a specific area to be serviced, as an example of the selection for such a specific area may be to select the address of the desired area, such as '00 00 00 Seoul Seoul '(S201).

If a specific area is selected as in step S201. The service providing server 120 defines a specific parameter of a specific message corresponding to the selected specific region (in this embodiment, the specific message is defined as a system parameter message configured as shown in Table 1 below, and the specific parameter constitutes the system parameter message. One or more of the various system parameters may be selected as a combination. Here, NID and BASE_ID may be defined.) May be acquired through a database provided in the home or the mobile positioning system 140 (S202).

That is, in step S202, the system parameter message transmitted from the base station of the mobile communication system of the area is extracted based on the area selected in step S201 to extract and acquire a specific system parameter necessary to distinguish it from other areas. In the present embodiment, the system parameters are defined as NID and BASE_ID as described above. However, the present invention is not limited thereto. The SID parameter indicates a system ID (ID) of an operator unit according to the selected region, and the ID (ID) of a unit network. One or more combinations of an NID parameter indicating a, a REG_ZONE parameter defining a registration zone, and a BASE_ID parameter as base station identification information may be defined and used as the system parameter as a specific parameter of the system parameter message.

Subsequently, the service providing server 120 transmits the obtained specific system parameter information to the mobile terminal 110 of the subscriber through the transmission network 130 in response to step S201, or the mobile positioning system. When configuring the 140, the specific system parameter information may be transmitted from the mobile positioning system 140 to the mobile terminal 110 through the transmission network 130 according to a short message service method (S203).

Finally, the mobile terminal 110 receives and stores the transmitted specific system parameter, and then receives the system parameter message generally transmitted from the mobile communication system so that the stored specific system parameter is received in the received system parameter message. In the idle state, whether the corresponding system parameter in the system parameter message, that is, whether the system parameter matching the stored specific system parameter exists in the system parameter message received from the mobile communication (Continued) to continue to search (S204) .

Since it is applied to, it will be described in parallel with the operation.

First, the mobile terminal 110 continuously searches for a system parameter message currently received in the idle state as in step S204 of FIG. 2 (S301), and as a result of the search, the specific system parameter received and stored in step S204 and It is determined whether or not a matching system parameter is received. If the previous state was an unreceived state of the matching parameter, it is determined whether or not it is currently received (S302), and if the previous state was a reception state of the matching parameter, the current state is determined. It is determined whether or not the state is not received (S303).

Subsequently, the mobile terminal 110 notifies the service providing server 120 of the determination result in step S302 or S303 (S304), and the service providing server 120 moves the mobile terminal based on the notification result. It is determined whether or not the service is available to the terminal 110 to selectively provide a service. The method may include, for example, a notification that the notification result is changed from a previous unreceived state to a current received state, that is, in step S302. If it is determined that the notification is a result of the determination, the mobile terminal 110 determines that the mobile terminal 110 enters and is located in the specific service area selected in step S201, thereby providing a service through a callback URL or a WAP PUSH communication method. Provide the mobile terminal 110 as necessary, and change the notification result from a previous reception state to a current unreceived state. If it is determined that the notification about the warning, that is, the notification of the determination result in step S303, the mobile terminal 110 determines that the service is out of the specific service area selected in step S201 (S305, S306).

The CP 11 sends the push message to the PPG 12 together with a user-defined-identifier, for example 'username@sktelecom.com'. The PPG 12 has mapping information between the user-defined-recognizer and the temporary (IMSI) and possibly the IP address (S401).

When the PPG 12 receives the push message, the MS 14 checks whether it has a Poit-to-Point Protocol (PPP) session or not. If not already having a PPP session, the PPG 12 uses a short message to send a Session Initiation Request (SIR) message to a Short Message Service Center (SMSC) 13. Send to (S402).

The SMSC 13 sends the received SIR short message to the corresponding MS 14 (S403). When the corresponding MS 14 receives the SIR short message, the MS 14 activates a Session Initiation Application (SIA) (S404).

The SIA of the MS 14 creates a push session with the PPG 12 (S405). The PPG 12 transmits a push message to the MS 14 using the created push session (S406), and the MS 14 sends an application defined in a push message header to process the push message. It performs (S407).

As described in detail above, according to the method and apparatus for confirming the location of a terminal in a wireless Internet network according to the present invention, when a subscriber mobile terminal is located in a specific area or leaves the area, it is possible to check this in the wireless Internet network.
