Abstract

PURPOSE: To eliminate a need of redialing or automatic answering service by reporting the return to the originating side or connecting a portable radio terminal to the originating side at need in the case of return of this portable radio terminal from the outside of a service area to the inside of the service area. CONSTITUTION: When the incoming call response of a portable radio terminal 4 is time-out, a radio base station 3 reports 'outside' to an originating terminal 1 and confirms the report indicating whether the terminal 1 should use the report service for return into the service area or not. If the terminal 1 responds to report confirmation with 'use', the telephone number of the terminal 1 and the discrimination number of the terminal 4 are stored as outside setting. The base station 3 requests the terminal 4 set outside to terminate the call in the idle time at intervals of a relatively long time by a network controller 2. When the terminal 4 returns to the original position area, the terminal 4 receives the call terminating request from the base station 3 and returns the incoming call response. The base station reports this incoming call response to the controller, and then, the controller 2 uses the telephone number corresponding to the discrimination number to report the return into this area to the terminal 1.

(Abbreviated as S) etc., the zone covered by the radio base station is composed of small zones with a radius of 100 to 200 m. The smaller the zone, the more radio base stations are needed to provide the service area. Also, even for wireless base stations in relatively large zones such as automobiles and mobile phones, the equipment cost is huge, so it is difficult to realize a wide service area at the start of service, and gradually expand the service area. Method is adopted. Therefore, there are many areas outside the service area, including the electromagnetic interference area (tunnel, underground, etc.).

Conventionally, in automobiles and mobile phones, when the network receives a call request from the outside to terminals outside the service area, the network notifies the calling side that connection is impossible or provides an answering machine service.

[0004]

However, according to this conventional method, the calling side only knows that the connection is impossible,
It is necessary to call again to make a call. In addition, there is a problem that the answering machine also requires the receiving side to receive the message, and the sending side cannot confirm the message.

In consideration of such conventional service problems, the present invention notifies the calling side of it when necessary when the portable terminal returns from the outside of the service area to the inside of the service area, or automatically. It is an object of the present invention to provide an area return notification device that does not require redialing or answering service by connecting.

[0006]

In order to achieve this object, the present invention provides a mobile communication system comprising a mobile radio terminal and a radio base station for radio communication, together with a telephone number of a caller and a mobile radio of a callee. Remember the terminal identification number,
And a means for deleting, a means for periodically making an incoming call request of the portable wireless terminal to the wireless base station in the current location registration area from the stored identification number, and a portable wireless terminal location-registered in another location registration area. Means for comparing the stored identification number with the identification number, and means for notifying the originating side of the return of the portable wireless terminal to the calling side using the telephone number when the identification numbers match or there is an incoming call response, The network control device is provided with a means for connecting a line between the portable wireless terminal that has been restored within the area and the calling side.

[0007]

With this configuration, when the portable wireless terminal moves to another location registration area, the location registration confirms the return to the service area, and when the portable wireless terminal returns to the original location registration area, a periodic incoming call request is made. It is possible to confirm the return by the response to, and it is possible to notify the calling side that the connection is possible, and it is possible to automatically connect the portable wireless terminal and the calling side.

[0008]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows the configuration of a first embodiment of an in-area return notification device of the present invention according to claims 1 and 2.

The originating terminal 1 requests the network control device 2 to make a call from the portable wireless terminal 4. In addition, a response from the network control device 2 to a notification confirmation (whether the mobile wireless terminal 4 wishes to be notified of return to the service area), a return notification to the service area, or a connection confirmation (confirm whether to connect to the mobile wireless terminal 4 that has returned to service). To the network control device 2.

The network control device 2 notifies the wireless base station 3 within the location registration area of the incoming call request of the portable wireless terminal 4 in response to the outgoing call request from the calling side terminal 1. Further, the notification of the notification is notified to the originating terminal 1 by the timeout of the incoming call response, and the response to the notification is received. The incoming call request is periodically transmitted to the wireless base station 3 in the location registration area, and the location registration information is confirmed. The originating side terminal 1 resets the service area by receiving an incoming call from the wireless base station 3 or registering the location of the portable wireless terminal 4.
Will be notified and the connection will be confirmed. The portable wireless terminal 4 and the caller terminal 1 are connected in response to the connection confirmation from the caller terminal 1.

The radio base station 3 notifies the portable radio terminal 4 of the incoming call request from the incoming call request from the network control device 2, and
The network controller 2 is notified of an incoming call response from the portable wireless terminal 4. When the location registration is accepted from the mobile wireless terminal 4, the network controller 2 is notified.

The portable wireless terminal 4 notifies the wireless base station 3 of an incoming call response from the incoming call request from the wireless base station 3. Further, when the location registration area is changed, the location is registered in the network control device 2 via the wireless base station 3. The present embodiment is configured so that the above can be performed. The operation will be described in detail below.

Operation flowcharts of the network control device 2 are shown in FIGS. First, the originating terminal 1 is the portable wireless terminal 4
To the network control device 2 (step S
1), the network control device 2 notifies the wireless base station 3 of the location registration area in which the portable wireless terminal 4 is registered to notify the incoming call request and activates a timer (steps S2, S).
3).

Upon receiving the incoming call request, the wireless base station 3 wirelessly transmits the incoming call request to the portable wireless terminal 4 (step S).
4). When the incoming call response is received from the portable wireless terminal 4, the network control device 2 is notified of the incoming call response, but not when there is no incoming call response.

The network control device 2 connects the line between the caller side terminal 1 and the portable radio terminal 4 if the incoming call response is notified from the radio base station 3 before the timer indicates timeout (steps S4 and S5). If the step S18) times out, it is determined that the portable wireless terminal 4 exists outside the location registration area or is in a state of being unreceivable, and "out of range" is notified to the calling side terminal 1 (step S6). Confirmation of whether or not to use the in-area return notification service is performed (step S7). If the response of the calling side terminal 1 to the notification confirmation is "use" (step S8), the identification number of the portable wireless terminal 4 is stored as the out-of-range setting together with the telephone number of the calling side terminal 1 (step S9). If "not used", the communication with the originating terminal 1 is disconnected (step S19).

The network control device 2 makes an incoming call request of the portable wireless terminal 4 set out of the service area at a relatively long interval in an idle time when there is no ordinary incoming call request to the wireless base station 3 in the location registration area. (Steps S10 and S11). In response to the incoming call request, the wireless base station 3 wirelessly transmits the incoming call request to the mobile wireless terminal 4. When the mobile wireless terminal 4 moves out of the location registration area and returns to the original location registration area, it can receive an incoming call request from the wireless base station 3 and returns an incoming call response to it (step S12). The wireless base station 3 notifies the network control device 2 of this incoming call response. Upon receiving the incoming call response, the network control device 2 determines that the portable wireless terminal 4 has returned to the location registration area, and notifies the originating terminal 1 of the return to the service area by using the telephone number corresponding to the identification number (step). S15).

When a location registration request is issued via the wireless base station 3, it is compared whether the identification number for location registration matches the identification number of the portable wireless terminal 4 set as out-of-range (steps S13, S14). When the portable wireless terminal 4 moves from the registered location registration area to another location registration area, it newly performs location registration. Therefore, if the identification numbers match, it can be determined that the mobile wireless terminal 4 has moved from outside the location registration area to another location registration area. Then, the originating terminal 1 is notified of the return to the service area using the telephone number corresponding to the identification number (step S15).

At this time, the calling side terminal 1 is notified of the return to the service area, and if the calling side terminal 1 desires the connection confirmation, the line with the portable wireless terminal 4 is connected (step S).
15, S16).

Next, the configuration of the second embodiment of the present invention according to claims 3 and 4 will be described. The block diagram is similar to that of the first embodiment.

The calling terminal 1 requests the network control device 2 to call the portable radio terminal 4. Further, the network control device 2 notifies the network control device 2 of a notification confirmation, a return to area notification, and a response to the connection confirmation.

The network control device 2 notifies the wireless base station 3 within the location registration area of the incoming call request of the portable wireless terminal 4 in response to the outgoing call request from the calling side terminal 1. Further, the notification of the notification is notified to the originating terminal 1 by the timeout of the incoming call response, and the response to the notification is received. When the location registration of the mobile wireless terminal 4 is received from the wireless base station 3, the originating terminal 1 is notified of the return to the service area and the connection is confirmed. The portable wireless terminal 4 and the caller terminal 1 are connected in response to the connection confirmation from the caller terminal 1.

The radio base station 3 notifies the portable radio terminal 4 of the incoming call request from the incoming call request from the network control device 2, and
The network controller 2 is notified of an incoming call response from the portable wireless terminal 4. When the location registration is accepted from the mobile wireless terminal 4, the network controller 2 is notified.

The portable wireless terminal 4 notifies the wireless base station 3 of an incoming call response from the incoming call request from the wireless base station 3. Also, when the user moves out of the service area, the internal information in the location registration area is deleted. When the location registration area is changed, the location registration is requested to the wireless base station 3.

The operation of the above configuration will be described.

First, when the originating terminal 1 makes a call request to the mobile radio terminal 4 to the network control device 2, the network control device 2 causes the radio base station 3 in the location registration area where the mobile radio terminal 4 is registered. To the incoming call request and start a timer.

Upon receiving the incoming call request, the wireless base station 3 wirelessly transmits the incoming call request to the portable wireless terminal 4. When the incoming call response is received from the portable wireless terminal 4, the network control device 2 is notified of the incoming call response, but not when there is no incoming call response.

If the incoming call response is notified from the wireless base station 3 before the timer indicates the timeout, the network controller 2 connects the line between the originating terminal 1 and the portable wireless terminal 4, but if the timeout occurs, the mobile controller 2 connects the portable terminal. The wireless terminal 4 determines that the wireless terminal 4 exists outside the location registration area or is in an unreceivable state, notifies the calling side terminal 1 of “out of range”, and confirms whether or not to use the area return notification service. If the response of the calling terminal 1 to the notification confirmation is “use”, the identification number of the portable wireless terminal 4 is stored as the out-of-range setting together with the telephone number of the calling terminal 1. If not used, the communication with the originating terminal 1 is disconnected.

When a location registration request is made via the radio base station 3, the network control device 2 compares the identification number for location registration with the identification number of the portable radio terminal 4 set as out-of-range. When the mobile radio terminal 4 cannot receive the radio wave of the radio base station 3, the location registration information is erased from the inside. Therefore, relocation registration is performed when a new radio wave can be received. Therefore, if the identification numbers match, it can be determined that the mobile wireless terminal 4 has moved from the outside of the service area to the inside of the service area. Then, the calling side terminal 1 is notified of the return to the service area using the telephone number corresponding to the identification number.

At this time, the originating terminal 1 is notified of the return to the service area, and if the originating terminal 1 desires the connection confirmation, the line with the portable wireless terminal 4 is connected.
