Description

Method and device for determining the location of a terminal in a wireless internet network {Method and Apparatus for notifying Location of MS in wireless inernet}

The present invention relates to a method and a device for identifying a location of a terminal in a wireless Internet network. More specifically, when a subscriber mobile terminal is located in or out of a specific area, various location-based services can be checked in the wireless Internet network. The present invention relates to a terminal positioning method and apparatus in a wireless Internet network.

In general, a method of determining the location of a mobile terminal in a wireless Internet network includes a method of transmitting a location value of a terminal to a user agent field when a user of the mobile terminal is connected to a WAP. For example, there is a method of determining a location of a terminal by using a page request method by accessing a specific service, but this is a limited method in which a service is provided only when a user requests it.

Of course, if the server periodically detects the location and the user visits a specific area, the user may provide a specific service to the user, but this is a burden of constantly tracking the location of the terminal. There is a drawback that cannot be provided to general purpose users.

On the other hand, as described above, even if a user does not access a specific service, the terminal location is provided to provide a service such as an advertisement. For example, a broadcasting (MSC) or cell-based broadcasting method of a mobile communication network is provided. Although this has been proposed, this is not a method of providing a service to a specific user of a specific region, but a method of transmitting a message to all users of a specific region, and as another example, location change registration signaling when a terminal enters a specific region. It is possible to register its own location by sending a message to the switching network, but this is not necessarily a service of a specific base station unit because the location is not necessarily registered when moving between the base stations of the terminal in the corresponding specific zone (generally Zone), To compensate for this, you may want to narrow the location registration area (usually Zone). There is a problem in that the value register request signaling so many leading to the load on the network.

The present invention has been made to solve the above problems, the object of which is to provide a variety of location-based services by allowing the mobile station to check if the mobile terminal is located in or out of a specific area. However, in particular, to provide a method and apparatus for determining a location of a terminal in a wireless Internet network, which enables location-based services in a base station unit area.

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).
