Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used in a mobile communication device using a small portable mobile device. In particular, the present invention relates to wireless control of mobile communication using a mobile device in which an antenna is pulled out at the time of use.

[0002]

2. Description of the Related Art In recent years, mobile communication represented by car phones and mobile phones has been remarkably widespread, and along with this, miniaturization of mobile devices has been advanced. The antenna of the portable device is also required to be downsized, but the antenna requires a certain physical size due to its characteristics, and there is a limit to downsizing. Therefore,
Generally, a structure is used in which a rod-shaped antenna can be stored in a housing and the antenna is pulled out when used.

[0003]

In the structure in which the antenna is stored in the housing, the antenna may be pulled out and used during a call, but the antenna remains stored in the housing except during a call, which is naturally effective. The significant gain is significantly reduced. A particular problem here is that the antenna of the mobile device is normally in a stored state when an incoming call arrives at the mobile device. Therefore, the transmission of the response signal to the calling signal from the base station is performed with the antenna housed. The transmission power of the base station can be increased to some extent, and reception can be performed even when the antenna of the mobile device is stored. However, it is extremely difficult to increase the transmission power of the mobile device due to the size of the mobile device and the limitation of the battery. Further, even when a call is not received, there is a possibility that the antenna may be operated with the antenna stored.

As described above, in order to miniaturize the portable type mobile device, it is effective to make the antenna housed in the main body, but in that case, the reliability of the signal transmitted in the antenna housed state is significantly lowered. However, there is a drawback that the serviceability such as the connection rate is impaired. On the other hand, in order to secure the signal reliability, it is necessary to increase the transmission power of the mobile device or reduce the size of the wireless zone. In the case of the former, it is not possible to satisfy the demand for miniaturization of portable mobile devices,
In the latter case, it is necessary to install a large number of base stations within the service area, which has the drawback of impairing the economic efficiency of the communication network.

An object of the present invention is to solve the above problems and to provide a mobile communication device capable of transmitting a signal with high reliability even in a portable mobile device with an antenna stored therein.

[0006]

According to a first aspect of the present invention, when a mobile station sends a signal to a base station but there is no response, a means for confirming the stored state of the antenna and the antenna store And a means for sending an alarm to the user when it is confirmed that the same signal is transmitted to the base station again after the antenna is pulled out. To be done.

The signal transmitted to the base station is, for example,
There are a response signal to the calling signal from the base station, a calling signal, a location registration request signal, and the like.

Sound, light, vibration or the like can be used as the alarm.

According to a second aspect of the present invention, the mobile device is
When the call signal is received from the base station while the antenna is stored, the first response signal is sent to the base station and an alarm is issued to the user, and the antenna is pulled out after the alarm is issued. And a means for transmitting a second response signal to the base station when the base station
Means for notifying the caller that there is a response from the mobile device when the first response signal or the second response signal is received, and within a predetermined time after sending the call signal. Means for notifying the caller that there is no response from the mobile when the first response signal is not received.

It is desirable that the means for issuing an alarm is configured to continue the alarm until the antenna is pulled out or the call signal is received and thereafter the disconnection signal from the base station is received.

The response signal means a control signal transmitted by the base station to a signal transmitted by the mobile device, such as a channel designation signal for incoming call, a position registration confirmation signal for position registration, a reception confirmation signal for packet signal transmission. .

[0012]

When a signal is transmitted from the mobile unit to the base station while the antenna is in the retracted state, the mobile unit determines whether or not the transmission signal has reached the base station. An alarm notifies the user, and the user who notices this sends a signal again by pulling out the antenna. If the propagation condition is good, such as when the mobile device is near the base station, signal transmission is possible even when the antenna is stored, and it is not necessary to issue an alarm. Only when the transmission condition is not good, an alarm is issued, and the signal is retransmitted after the antenna gain is set to a high state, so that reliable signal transmission is possible.

1 is a block diagram showing the configuration of a mobile communication apparatus according to an embodiment of the present invention, and FIG. 2 is a block diagram showing the configuration of a mobile device.

This mobile communication device comprises a portable mobile device 1 provided with an antenna 11 at least a part of which can be stored in a housing, and a base station 2 to which the mobile device 1 is wirelessly connected. The base station 2 is connected to the communication network 3. The mobile unit 1 includes an operation unit 12, a voice input / output unit 13, and an alarm generation unit 1.
4, the control unit 15 and the transmission / reception unit 16 are provided, and the antenna 11 is attached to the transmission / reception unit 16. The alarm generation unit 14 generates an alarm by sound, light, vibration, or the like. When an alarm is generated by sound, the alarm generation unit 14 can be provided in the voice input / output unit 13.

3 to 4 show a control unit 15 in the mobile unit 1.
5 is a flowchart showing the control by the above in association with the control of the base station, showing different control examples.

The example shown in FIG. 3 shows a basic flow. The mobile device that needs to send a signal waits for the reception of a response signal from the base station 2 after sending the signal. When the response signal is received within the fixed time, it means that the signal has surely arrived at the base station, and therefore, if necessary, a conventional conventional process (not shown) is performed. When the response signal cannot be received, it is determined whether or not the antenna is stored, and when the antenna is not stored, it is determined that the signal transmission has failed, and the conventional normal processing (not shown) is performed. )I do. If stored, the alarm generation unit 14 shown in FIG. 2 is caused to generate an alarm due to sound, light, vibration or the like which can be detected by the user. When the user notices this alarm and pulls out the stored antenna, the same signal is sent again to the base station. After that, the conventional normal processing such as waiting for a response signal is performed. The alarm may continue to be generated until the user pulls out the antenna, or may stop after a certain time has elapsed.

The example shown in FIG. 4 relates to an incoming call to a mobile station.

When the mobile station receives an incoming call, the base station sends an incoming call signal to the mobile station. Upon receiving the incoming call signal, the mobile device sends a response signal to the base station. Upon receiving the response signal, the base station sends a channel designation signal for communication to the mobile station and sends a ringback tone to the caller as in a normal telephone. Upon receiving the channel designation signal, the mobile device switches to the designated channel. After that, the mobile unit generates a sound, light or vibration alarm for the user to notify the user that the incoming call is received. As a result, the call is started when the user goes off-hook. The alarm in this case is an incoming call alarm corresponding to a bell in a normal telephone.

When the antenna of the mobile device is stored, the response signal may not be received by the base station. In that case, the base station sends an announcement to the caller that the mobile is ringing. As a result, the caller knows that the mobile device he is trying to call did not send the response signal or did not reach the base station even if it sent it, and in the hope that the user will pull out the antenna for a while. I will wait as it is. On the other hand, the mobile device knows that the base station cannot receive the response signal by not receiving the channel designation signal, and checks whether the antenna is in the retracted state. If it is not in the storage state, it is determined that the incoming call has failed, and the conventional normal processing is performed. If stored, the sound,
Generates an alarm due to light or vibration. If the user notices this and pulls out the antenna, the response signal is again sent to the base station at this point, and the channel designation signal from the base station is awaited. When the calling party gives up the announcement after sending the announcement that the calling is being made, the base station sends an incoming call cancellation signal to the mobile station. When the mobile station receives this signal, it stops the alarm and returns to standby or other conventional normal processing.

The example shown in FIG. 5 relates to location registration of a mobile device.

The location registration is to register the location of a mobile device in the base station in units of this area, using a plurality of wireless zones as location registration areas, and is used in automobile phones and the like. For this location registration, the location information is sent from the base station in units of location registration areas, and the mobile station stores the location information of its own location registration area. When the mobile device moves and leaves the position registration area, the position information stored so far and the position information received in the transfer destination area are different. The mobile device that has detected the change in the position information in this way sends a position registration request signal to the base station. Upon receiving the location registration request signal, the base station sends a location registration acceptance signal to the mobile device. When the mobile device receives the position registration acceptance signal, it considers that the position registration is completed, and rewrites the position information memory in the mobile device with new position information. The above is the conventional normal position registration operation.

The control flow of the mobile unit after transmitting the position registration request signal is the same as the example shown in FIG. That is,
If the location registration acceptance signal is not received within a certain time after the location information registration request signal is sent, the mobile device checks whether the antenna is in the stored state. As a failure, the conventional normal processing is performed. When in the stored state, an alarm is generated to the user by sound, light or vibration. When the user notices this and pulls out the antenna, the mobile device again sends a position registration request signal. The following operation is the usual normal processing,
It waits for reception of the location registration request signal and performs other processing.

[0023]

As described above, in the mobile communication device of the present invention, when the mobile device is miniaturized and the antenna is of a retractable type, an alarm is generated and the user is informed when it is necessary to pull out the antenna. Since the antenna is prompted to be pulled out, the signal can be transmitted from the mobile device to the base station with high reliability.
