Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a mobile communication terminal, and more particularly to a mobile communication terminal that is advantageously adapted and operated in a terminal that is moving at high speed.
[0002]
[Prior art]
A so-called mobile communication system such as a mobile phone or a car phone has a great feature that communication is possible even when the mobile communication terminal is moving, and has been rapidly spread in recent years.
[0003]
As is well known, in a mobile communication system, a base station that can perform good communication is conveniently selected from public base stations that are regularly arranged to enable communication even while moving.
[0004]
In such a base station selection process, when a mobile station moves between cells belonging to different location registration areas, the mobile station recognizes that the position information notified from the base station has changed from that before the transition. Is again requested from the base station for location registration.
[0005]
There is a case where a mobile phone receives an incoming call while moving on a car or a train (moving at high speed). In such a case, responding to this may cause an accident or may cause trouble for people around you. If you do not want to respond, turn off the mobile phone before riding the vehicle. There was a need.
[0006]
[Problems to be solved by the invention]
However, I often forgot to turn off the power before riding a vehicle or driving a car. In such a case, if there is an incoming call while driving a car, there is a risk of responding to this and leading to an accident.
[0007]
In addition, when responding to a mobile phone in a train or the like, a situation such as inconvenience other customers occurred. In addition, during high-speed movement, the operation of turning off the power and turning on the power when returning to the normal state may be troublesome.
[0008]
Accordingly, an object of the present invention is to provide a mobile communication terminal that functions safely by switching to a state different from a normal response at the time of an incoming call without turning off the power during high-speed movement.
[0009]
[Means for Solving the Problems]
Mobile communication terminal of the present invention, when migrating between cells belonging to different location registration area, to the base station belonging to the cell after migration, when performing re-location registration, when the standby state, to move the location registration area When the number of relocation registrations within the estimated time required for passing exceeds the specified number of times, a function different from the normal standby function is set.
[0010]
In the mobile communication terminal, when the number of relocation registrations does not increase for a certain period of time after setting the different functions, the different functions are canceled.
[0011]
The different functions can be a voice mail, Ba Eve configuration function, a function of notifying the fast moving to the handsfree function, or caller.
[0012]
Furthermore, when the mobile communication terminal of the present invention moves between cells belonging to different location registration areas, the mobile communication terminal is activated by the occurrence of a relocation registration operation when performing relocation registration for a base station belonging to the cell after the migration Timer means for counting, counter means for counting the number of occurrences of relocation registration operation,
First, it is determined whether or not the time measured by the timer means has exceeded the estimated time required for passing through the position registration area, and the number of occurrences of the relocation registration operation counted by the counter means And determining means for determining whether or not the predetermined number of times has been exceeded. When the first determining means determines that the estimated time has been exceeded, the timer means and the counter means are reset. When it returns to the standby state and is within the estimated time, when it is determined by the second determination means that it is within the specified number of times, only the timer means is reset to return to the standby state, and the specified number of times is set. When it is determined that the number has been exceeded, the operation is switched to the answering machine operation.
[0013]
In the mobile communication terminal, when the count value of the counter means does not increase for a certain time after shifting to the answering machine function operation, the answering machine function operation is canceled.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
[0015]
FIG. 3 is a block diagram showing the overall configuration of a mobile communication terminal to which the present invention is applied. The transmission / reception circuit 1 is controlled by the CPU 2 to perform transmission / reception operations. The CPU 2 operates according to signals from the operation keys 6 and the transmission / reception circuit 1 according to a program written in the ROM 8, and controls the transmission / reception circuit 1 and the LCD driver 3. The CPU 2 uses the RAM 7 as a temporary storage memory.
[0016]
The LCD driver 3 is controlled by the CPU 2 and causes an arbitrary font in the font ROM 5 to be displayed at a designated location on the LCD 4.
[0017]
In addition, the CPU 2 controls the audio processing unit 9 to process audio signals from the speaker 10 and the microphone 11.
[0018]
FIG. 2 is a diagram showing a procedure in which a mobile communication terminal (mobile station) such as a mobile phone registers a predetermined position with a base station.
[0019]
As shown in FIG. 2A, a base station BS (A, B, C) is provided for each cell, and this same cell is set as a location registration area of the base station BS. Therefore, the base station BS transmits location registration area numbers as location information to all mobile stations MS1, MS2, and MS3 in the location registration area. When the mobile stations MS1, MS2 and MS3 receive the position information from the base station BS, they return a position registration request to the base station BS in order to register it.
[0020]
FIG. 2B is a diagram for explaining the procedure of relocation registration when the mobile station MS moves to a cell belonging to a different location registration area. The operation of registering the predetermined position of the mobile station is performed in units of position registration areas. The mobile station MS that is traveling in the location registration area (A) receives location information from the base station BS (A) in this area and performs location registration. Here, when the mobile station MS moves to the location registration area (B), the location information sent from the base station (B) belonging to the location registration area (B) is different from the previously registered location information. Therefore, if the location information received in the new registration area is different from the previously registered location information, the mobile station MS again requests location registration from the base station BS (B) belonging to the location registration area (B). To do.
[0021]
In the present invention, this location registration operation is used to detect high-speed movement, and the standby operation of the mobile station is switched to the answering machine function.
[0022]
FIG. 1 is a flowchart for explaining the operation of the present invention. When the power of the mobile station MS is turned on (step 101), the mobile station MS first performs location registration with respect to the base station in the current location registration area (step 102). At the same time, the timer and counter initial values provided in the mobile station MS are set to zero.
[0023]
After such an operation is performed, the mobile station MS enters a standby state (step 103). Relocation registration is required when the mobile station MS moves to another location registration area (step 104). When such relocation registration occurs, the mobile station MS determines the number of times of relocation registration after turning on the power by looking at the counter (step 105). That is, the counter starts counting when relocation registration occurs for the first time. When re-position registration is the first time (when the counter value is 0), the timer is started, the counter value is incremented by one, and the normal standby state is resumed (step 106). That is, the timer starts from the time when the relocation registration first occurs. If the relocation registration is not the first time, that is, if the count value of the counter is other than 0, this count value is incremented by one (step 107). Thereafter, it is confirmed whether or not the count value of the timer exceeds the specified time (step 108). Here, the specified time can be determined as a value obtained by dividing the diameter of the location registration area by the assumed speed of the mobile station MS. For example, when the diameter of the location registration area is 20 km and the assumed moving speed of the mobile station is 100 km / h, the specified time is 12 minutes. If the timer exceeds the specified time, it is regarded as a low-speed movement, and both the timer and the counter are reset to 0 and the normal standby state is restored (step 109). If the timer is within the specified time, the counter value is further checked to confirm how many times re-position registration has been performed.
[0024]
If the specified number of times has not been exceeded (reposition registration is still a small number of times), there is a suspicion of high-speed movement and the timer is reset to 0, but the counter count value is kept as it is and normal standby is again performed Return to the state (steps 110 and 111).
[0025]
If the count value of the counter exceeds the specified number in step 110 (relocation registration occurs many times), it is regarded as high-speed movement (step 112), and the mobile station MS is automatically switched to the answering machine operation (step 110). Step 113). After that, the normal standby state is restored. In addition, after entering the answering machine state, it is checked whether or not relocation registration is still being performed every few minutes, and if relocation registration has not been performed for several minutes (the mobile station in the same location registration area) If this is the case, this mobile station is considered to be moving at a low speed and cancels the answering machine operation.
[0026]
In the above-described embodiment, the high-speed movement determination operation is performed on the mobile terminal side, but may be performed on the base station side (network side). Moreover, although it is configured to switch to the answering machine function when it is determined that it is moving at high speed, the incoming call may be automatically shifted to the vibrator function.
[0027]
In this way, if the vehicle is on a vehicle such as a train, the ringer sound does not sound, so the inconvenience to other customers is reduced. In addition, when it is determined that the vehicle is moving at high speed, it is possible to shift to the hands-free function.
[0028]
By shifting to such a function, it is possible to make a call while continuing driving, so that safety is not impaired. Further, when it is determined that the vehicle is moving at high speed, this may be automatically notified to the caller to notify that the mobile communication terminal is driving or in a train.
[0029]
Furthermore, the present invention is also applicable to GSM terminals (900 MHz) and DCS1800 (1800 MHz) mobile radio terminals found in PHS (Personal Handyphone System) terminals, mobile phones, and GSM (The GSM System for Mobile Communication) systems. Needless to say.
[0030]
【The invention's effect】
As described above in detail, in the present invention, this is automatically extracted during high-speed movement and set to have a function different from the normal standby operation, so even if you forget to turn off the power before riding the vehicle, Will no longer bother customers and reduce the risk of accidents while driving.
