Abstract

PROBLEM TO BE SOLVED: To provide a mobile station that can automatically control a sending and receiving suppression mode without the need for an installation investment for a base station side at present. SOLUTION: The control apparatus is provided with a CPU section that calculates the status of a radio wave in the case of communication of a mobile terminal with a base station and in its standby state, decides a base station most suitable for the communication, sets the base station to a wireless control section, calculates the switching operation of the base station to be communicated, the radio wave strength and the switching time of the base station to be communicated, and commands a sending and receiving control section of a phone section to conduct sending and receiving suppression control. A sending and receiving suppression section shifts to a sending and receiving suppression mode set in advance to suppress the sending and receiving of the phone section. The CPU section commands the sending and receiving suppression section to shift to the sending and receiving suppression mode when the difference between the absolute values of the strength of an electric field passing through cells and fluctuations in the electric field strength just before and just after the production of the switching of a communication opposite party are equal to or over a predetermined threshold value and when a mean moving speed of the mobile station due to a switching time between preceding cells and current cells exceeds a threshold.

It is determined whether or not the vehicle is moving at high speed using the value of the moving speed information in the section,
A device that determines whether to set the incoming call notification mode to sound or to vibrate the housing according to the determination result is disclosed. In this conventional apparatus, since the Doppler shift occurs in the carrier generated due to the movement of the mobile terminal apparatus, the maximum Doppler frequency is obtained from the difference between the carrier frequency at which the maximum Doppler shift occurs and the reference carrier frequency, and the movement at that time is determined. Speed is uniquely sought.

[0003] For example, Japanese Patent Application Laid-Open No. 11-275649 discloses a system for automatically prohibiting an incoming call response of a mobile terminal device in an incoming call prohibited area. The second oscillator for transmission, the incoming call response permission area A includes a first oscillator for transmitting a signal of a predetermined frequency S1 having a frequency different from that of the second oscillator, and when a mobile terminal is present in the area B, the control is performed. A configuration is disclosed in which the control unit 26 prohibits an incoming call response, stores a message from a caller in an internal memory unit, and permits the incoming call response when the control unit 26 exists in the area A.

[0004]

In the case of such a configuration, there is a problem that it is necessary to add equipment to the base station as well as the mobile station. It is also necessary to consider a method for preventing a mobile station from receiving a transmission / reception suppression request radio wave for a mobile station other than for the purpose of ensuring suppression.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made in view of the above-mentioned problems, and an object of the present invention is to automatically suppress outgoing / incoming calls on the mobile station side without requiring capital investment for the current base station side. It is an object of the present invention to provide a mobile station capable of controlling a mode, an automatic transmission / reception control device thereof, and a recording medium on which a program is recorded.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an embodiment of the present invention; FIG. 1 is a diagram showing a configuration of a mobile station (portable mobile radio telephone) 10 according to one embodiment of the present invention.
Referring to FIG. 1, in one embodiment of the present invention, a wireless control unit 1 receives signals from base stations A and B during standby and during a call and measures the electric field strength (sensitivity). C
The PU unit 2 extracts the electric field strength from the wireless control unit 1, calculates the switching interval of the communication base station, and determines whether the mobile station is moving at high speed.

When the CPU unit 2 determines that the mobile station is moving at a high speed, the transmission / reception control unit 4 shifts the mobile station to the transmission / reception suppression mode according to a pattern registered in advance.

Normally, the radio control unit 1 intermittently receives signals from a plurality of base stations and always measures the radio wave intensity (electric field intensity).
The measurement result is calculated by the CPU unit 2, the CPU unit 2 selects an optimal base station, and based on the selection result, the wireless control unit 1
Changes the base station with which to communicate.

FIGS. 2 (a) and 3 (a), FIGS. 2 (b) and 3 (b) show examples of the radio field intensity calculated by the CPU section 2. FIG.

FIGS. 2A and 2B show the arrangement of base stations. In FIG. 2, a radio communication range (hereinafter, referred to as a “cell”) covered by one base station is represented by one hexagon.

FIGS. 3 (a) and 3 (b) show the case where the mobile station is A → B in FIGS. 2 (a) and 2 (b), respectively.
→ C indicates the relationship between the radio field intensity obtained when moving and the time at the time of moving.

In FIG. 2A, in the order of A → B → C,
When the mobile station moves, as shown in FIG. 3 (a), the communication partner is changed to each optimal base station through cells C1 → C2 → C3. In this case, in order to select an optimal base station, the CPU unit 2 makes a determination based on the electric field intensity measured by the wireless control unit 1.

The approximate size of one cell is several kilometers in an urban area. By measuring the size of this cell and the time from the previous cell switching to the current cell switching, the approximate average moving speed of the mobile station can be calculated.

When the calculated average moving speed exceeds a predetermined threshold value, the CPU 2 issues a command to the outgoing / incoming suppressing unit 4 in the telephone unit 3, and the outgoing / incoming suppressing unit 4 Is automatically shifted to a predetermined transmission / reception suppression mode.

Conversely, when the calculated average speed is equal to or less than a predetermined threshold, the CPU 2 issues a command to the call-sending suppression unit 4 in the telephone unit 3 to automatically cancel the call-sending / reception suppression mode.

By the way, only by moving between cells, the CPU
When the unit 2 measures the average moving speed, as shown in FIG. 2B, when the mobile station moves slowly near the switching point of the cell (base station) of the communication partner, a short distance In spite of (low speed) movement, the average moving speed calculated by the CPU unit 2 exceeds the threshold.

Therefore, in one embodiment of the present invention, the flow may be controlled as shown in FIG. 4 in order to avoid this problem.

When a handover occurs (step 401),
It is determined whether or not the absolute value of the radio field intensity difference during passage through the cell is equal to or greater than a predetermined threshold (second threshold) (step 40).
2) When the absolute value of the radio field intensity difference during cell passage is equal to or larger than the second threshold, the fluctuation (variation) of the radio field intensity near the occurrence of handover is equal to or larger than a predetermined threshold (third threshold). It is determined whether or not there is (step 403), and if the fluctuation is equal to or greater than the third threshold, it is determined whether or not the calculated average moving speed is equal to or greater than the threshold (first threshold) (step 4).
04) If the calculated average moving speed is equal to or higher than the first threshold value (Y branch in step 404), and if the current mode is not the outgoing / incoming call suppression mode (N branch in step 406), the mode is shifted to the outgoing / incoming call suppression mode (step S406). 408) In the case of the current outgoing / incoming call suppression mode, the process returns to the standby state in step 401 in the outgoing / incoming call receiving mode.

On the other hand, if it is determined in step 404 that the calculated average moving speed is not equal to or greater than the first threshold, the current call origination / reception suppression mode is set (Y in step 405).
(Branch), and release the incoming / outgoing call suppression mode (step 40)
7) If it is not currently in the outgoing / incoming call suppression mode, step 40
It returns to the standby state of 1.

As described above, in one embodiment of the present invention, in addition to the determination based on the cell switching time (step 104), the CPU 2 determines the difference between the absolute values of the electric field strength (step 102) and the cell switching time. The calculation is performed by adding the electric field intensity information immediately before and immediately after the occurrence of the switching (decay rate variation of the electric field intensity) (step 103).

The functions of the processing steps shown in FIG. 4 are realized by a program executed by the CPU 2 or the like of the portable mobile radiotelephone. In the present invention, the present invention can be implemented by reading and executing the program from a recording medium on which the program is recorded.

As is apparent from a comparison between FIG. 3A and FIG. 3B, when the cell greatly crosses the cell and when the cell moves in the vicinity of the cell, the cell is similarly switched. The absolute value of the electric field strength before that differs. Also, the slope of the graph before and after the cell switching occurs is significantly different.

By taking these items into consideration, the average moving speed can be calculated more accurately.

In addition, by enabling the user to set a threshold value for switching to the call origination / reception suppression mode and to enable / disable this function at the same time, a more realistic automatic switching can be provided in accordance with the usage environment of the user. it can.

In the above embodiment, the location information is based on the cell switching point (communication base station switching point). However, if location information is obtained from a base station such as a PHS, it is used as the location information. Thus, similarly, the average moving speed can be calculated, and the switching of the outgoing / incoming call suppression mode can be performed more accurately.

Another embodiment of the present invention will be described. In the second embodiment of the present invention, the basic configuration is the same as that of the above-described embodiment. In the second embodiment of the present invention, there is provided means for shifting to the incoming / outgoing call suppression mode performed by the CPU unit 2 and for confirming that the release command issuance condition is being used reliably in the vehicle. .

A vehicle-mounted kit may be used in a vehicle. In this case, a power source is obtained from the vehicle as an external power source. By adding the condition of the external power supply operation to the high-speed movement determination based on the average moving speed described in the above embodiment, the vehicle movement can be detected more accurately, and the shift to the incoming / outgoing call suppression mode when using the vehicle is performed. Can be performed more reliably.

The condition that the connection kit is being used may be added to the high-speed traveling determination.

Further, GPS (Global Positioning S)
ystem (Global Positioning System) If the hybrid terminal has a function, the current position / movement speed can be easily obtained, the movement can be determined more effectively, and automatic switching of the mode with high accuracy is provided. I can do it.

[0042]

As described above, according to the present invention,
The following effects are obtained.

The first effect of the present invention is that the user of the portable terminal device does not need to be aware of the setting of the incoming / outgoing call suppression mode and the like.
While moving in a vehicle, the mobile terminal device can be automatically shifted to the incoming / outgoing call suppression mode, improving operability and convenience, and improving the manners and safety of using the mobile terminal device. That is.

A second effect of the present invention is that, when the movement by a vehicle or the like is completed, the mode can be automatically shifted to the normal mode, and the operability and convenience are improved.

A third effect of the present invention is that it is possible to suppress the outgoing / incoming call of the mobile station without the need for capital investment on the base station side, thereby suppressing the increase in the development cost. .
