DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention makes it possible to notify a mobile communication terminal of place name information indicating a place name representing a wireless zone in which the mobile communication terminal is located in a mobile communication network. About the location notification method.

[0002]

2. Description of the Related Art In general, a mobile communication terminal transmits a position registration signal accompanying movement, whereby a position registration process of the mobile communication terminal is performed in a mobile communication network, and the mobile communication terminal performs a position registration process. The position of the body communication terminal can be ascertained.

Hereinafter, the location registration process will be described in detail.

[0004] The radio base station stores a local identification code corresponding to the radio base station, and constantly transmits the local identification code to a radio zone which is a communication area of the radio base station.

[0005] The mobile communication terminal stores an area identification code transmitted from a wireless base station in a wireless zone in which the mobile communication terminal is located.

The radio base station control station associates a radio base station identification code for identifying the radio base station with an area identification code corresponding to the radio base station for all the radio base stations. I remember. In addition, for all mobile communication terminals, the subscriber numbers of the mobile communication terminals and the area identification codes corresponding to the wireless base stations in the wireless zones where the mobile communication terminals are located are stored in association with each other. .

[0007] Considering the case where the mobile communication terminal has moved to a wireless zone corresponding to a different area identification code, the mobile communication terminal is transmitted from a wireless base station having a communication zone of the destination wireless zone. The area identification code is detected and compared with the area identification code stored in its own storage device. In this case, since the mobile communication terminal recognizes the change of the area identification code, the mobile communication terminal updates the area identification code stored in its own storage device and transmits the location registration signal including its own subscriber number to the radio base station. Send to the station.

[0008] The radio base station transfers the location registration signal transmitted from the mobile communication terminal to the radio base station control station. When the radio base station control station receives the location registration signal from the radio base station, the location registration signal is transmitted. Based on the subscriber number included in the registration signal, the area identification code stored in its own storage device in association with the subscriber number is updated.

[0009] In this manner, the location registration processing of the mobile communication terminal is performed, and the location of the mobile communication terminal can be ascertained in the mobile communication network.

[0010] When the mobile communication terminal moves to a portion where two or more wireless zones overlap, the mobile station receives the area identification code transmitted from the two or more wireless base stations. Detect the region identification code.

[0011]

In the above prior art, the area identification code is used only for performing the location registration process, and the mobile communication terminal stores the area identification code. However, it is not possible for the subscriber of the mobile communication terminal to refer to the area identification code.

[0012] Further, even if the subscriber of the mobile communication terminal can refer to the area identification code, the area identification code is not information that can be understood by humans.
The subscriber of the mobile communication terminal cannot know his / her current location.

On the other hand, as seen in a navigation system, a technique for displaying map information centering on the current position of a mobile communication terminal has been devised. However, there is a problem that the amount of hardware for displaying the map information needs to be installed, so that the capacity of the mobile communication terminal becomes large and portability is deteriorated.

On the other hand, as described in Japanese Patent Application Laid-Open No. 63-199528, there is a technique for notifying a subscriber of a general communication network of a position of a mobile communication terminal designated by the subscriber. It has been devised.

According to this technique, when a subscriber of a general communication network dials a predetermined special number, and then dials a subscriber number of a desired mobile communication terminal, the mobile exchange starts the mobile communication. An announcement indicating a wireless zone in which a terminal is located is transmitted to a subscriber of the general communication network.

However, with any of the conventional techniques,
The subscriber of the mobile communication terminal could not grasp his current position. In particular, when the subscriber of the mobile communication terminal is located in a location that is unfamiliar with geography, it is convenient to be able to easily grasp his / her current location.

An object of the present invention is to provide a location notifying method capable of notifying a mobile communication terminal of place name information indicating a place name representing a wireless zone in which the mobile communication terminal is located. It is in.

Another object of the present invention is to enable only a communication partner of a mobile communication terminal to be notified of place name information indicating a place name representing a wireless zone in which the mobile communication terminal is located. To provide a location notification method.

[0019]

In order to achieve the above object, the present invention provides a mobile communication terminal and a plurality of wireless base stations for performing wireless communication with the mobile communication terminal. A mobile communication network comprising a station, a radio base station control station for controlling these radio base stations in general, and a mobile exchange for connecting the radio base stations to each other or between the radio base station and a general communication network. In the above, each of the wireless base stations stores place name information indicating a place name representing a wireless zone which is its own communication area.

The mobile communication terminal is, for example,
When requesting place name information when transmitting a position registration signal, at the time of connection with a communication partner, at the time of an instruction from the outside, or at the time of elapse of a predetermined time, And transmits the place name request signal to the wireless base station, and upon receiving the place name request signal transmitted from the mobile communication terminal, the wireless base station sends the stored place name information to the mobile communication terminal. When the mobile communication terminal receives the place name information transmitted from the wireless base station, the mobile communication terminal outputs the place name information.

It is to be noted that the radio base station control station (or the mobile exchange) may store the place name information instead of the radio base station.

[0022] In this case, the radio base station control station (or the mobile exchange) transmits, for each of the radio base stations, identification information for identifying the radio base station and a communication range of the radio base station. Place name information indicating a place name representing a certain wireless zone is stored in association with the place name information.

When receiving the place name request signal transmitted from the mobile communication terminal, the radio base station transmits the place name request signal to the radio base station control station (or the mobile switching center). Upon receiving the place name request signal transmitted from the wireless base station, the wireless base station control station (or the mobile exchange) stores the place name request signal in association with the identification information corresponding to the wireless base station of the transmission source. Transmitting the place name information to the wireless base station, and upon receiving the place name information transmitted from the wireless base station control station (or the mobile switchboard), the wireless base station: The place name request signal is transmitted to the mobile communication terminal that transmitted the signal.

The mobile communication terminal stores the place name information transmitted from the radio base station, for example, when there is an instruction from outside, or when a predetermined time elapses. , The stored place name information may be output.

Further, in order to achieve the other object, according to the present invention, the mobile communication terminal stores the place name information transmitted from the radio base station.
The stored place name information is transmitted to the communication partner when the mobile communication terminal and the communication partner are connected or when the place name request signal transmitted from the communication partner is received. I am trying to do it.

In the case where the radio base station stores the place name information, the radio base station may be connected, for example, at the time when the mobile communication terminal is connected to its communication partner or at the time of the communication. The stored place name information may be transmitted to the communication partner when the place name request signal transmitted from the other party is received.

[0027]

For example, consider the case where each of the above radio base stations stores place name information indicating a place name representative of a radio zone which is its own communication area.

When the mobile communication terminal transmits the location name request signal to the radio base station when transmitting the location registration signal, for example, the mobile base station transmits the location name stored in the radio base station from the radio base station. Since the information is transmitted, the place name information is output.

As a result, the subscriber of the mobile communication terminal can
It is possible to grasp the current position of the user.

Further, the mobile communication terminal transmits the place name request signal to the wireless base station when, for example, a connection is established with a communication partner, and the mobile base station transmits the place name request signal to the wireless base station. Since the stored place name information is transmitted, the place name information is output.

As a result, it becomes possible for the subscriber of the mobile communication terminal to know his / her current location.

In this case, in particular, the mobile communication terminal stores the place name information transmitted from the wireless base station and, for example, stores the information when a connection with a communication partner is established. The place name information can be transmitted to the communication partner.

Thus, only the communication partner of the mobile communication terminal can grasp the current position of the mobile communication terminal.
