Abstract

PROBLEM TO BE SOLVED: To improve the operability by dispensing with dialing input of a long-distance call number when a local phone call is made from a mobile communication terminal equipment and making dialing match with an operation content in the case of dialing from cable terminal equipment. SOLUTION: Every time a mobile terminal equipment receives a base station number sent periodically from a base station at time for waiting reception, the mobile terminal equipment retrieves a base station map in a ROM 13, based on the base station number to read out a long-distance call number corresponding to a zone where its own terminal equipment is present on and to store it in a RAM 14. In the case of making dialing call operation in this state, whether dial push button data of a 1st digit are '0', or '1' or other number is discriminated. When the number is other than '0' or '1', it is discriminated that the dialing destination indicates a local call, after long-distance call number data are read out from the RAM 14 and sent to a base station, dial push button data after the 1st digit being inputted by dialing as the above are successively sent out to the base station.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a mobile communication terminal used as a PHS terminal in a PHS (Personal Handy Phone System), for example, and a base station for connecting the PHS terminal to a PHS network.

[0002]

2. Description of the Related Art In recent years, various mobile communication systems have been developed with the development of communication technology and the expansion of communication needs. As one of them, a mobile communication system called PHS has attracted attention.

In the PHS, for example, a plurality of base stations are geographically dispersed in a service area, and these base stations are respectively connected to a PHS network. Then, the PHS terminal existing in the wireless area formed by each base station is connected to the PHS network via the base station at the time of transmission / reception, and the PHS terminal is further connected to the PHS terminal.
By connecting to the public network from the S network, a call, data communication, and the like are enabled between the PHS terminal and another communication terminal connected to the public network.

[0004]

However, in PHS,
When a call is made from a PHS terminal, it is necessary to always transmit all digits of the dial information of the communication partner, including the area code, regardless of whether communication is performed with a communication partner located in any region. In other words, the area code must be sent to the PHS network when making a local call as well as when making a local call.

For this reason, the user of the PHS terminal must dial all the digits of the telephone number including the area code even when making a local call, and the operation is extremely troublesome. . Above all, the case where a call is made from a wired telephone despite the fact that the call is made to the same
Since the dial operation is different from the case of making a call from the S terminal, a problem such as erroneous dial operation or being perplexed is likely to occur, which is not preferable.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances. It is an object of the present invention to eliminate the need for dialing an area code when making a local call from a mobile communication terminal device. An object of the present invention is to provide a mobile communication terminal device and a base station device of a mobile communication system in which operability is improved by matching dial operation and operation content when transmitting from a device.

[0007]

In order to achieve the above object, the present invention provides at least one base station connected to a public network and a radio channel in a radio area formed by the base station. A mobile communication system comprising: a mobile communication terminal connected to the base station; and a function of notifying the mobile communication terminal from the base station of position information indicating the location of the mobile communication terminal. In the mobile communication terminal device, a recognizing means for recognizing an area code of an area where the own device is located based on the location information notified from the base station device, and a dialing partner of a communication partner input at the time of calling. A determination unit for determining whether or not the information includes an area code, and a dial information transmission control unit that operates in accordance with the determination result are newly provided. When the dial information transmission control means determines that the area code is not included by the determination means, the area code recognized by the recognition means is added to the input dial information. To be transmitted to the base station apparatus.

The present invention further comprises a display means in addition to the above means, and displays the area code of the area where the own device is recognized by the recognizing means at least before inputting the dial information by the display means. It is also characterized by doing so.

On the other hand, another invention relates to at least one base station connected to a public network and a mobile communication terminal connected to the base station via a wireless channel in a wireless area formed by the base station. The base station device used in a mobile communication system having a function of managing the position of the mobile communication terminal device based on terminal identification information transmitted from the mobile communication terminal device. ,
Recognition means for recognizing the area code of the area where the mobile communication terminal is located based on the terminal identification information transmitted from the mobile communication terminal, and a dial of a communication partner transmitted from the mobile communication terminal A determination unit for determining whether the information includes an area code and a dial information transfer control unit are newly provided. When the dial information transfer control means determines that the area code is not included by the determination means, the area code recognized by the recognition means is added to the dial information of the communication partner. And sends it to the public network.

As a result, according to the mobile communication terminal device and the base station device of the present invention, if the area code is not dialed when the mobile communication terminal device makes a call, the call is for a local call. Thus, the area code of the area where the mobile communication terminal device, which is recognized in advance, is automatically added and transmitted. For this reason, the user
Even when making a call using a mobile communication terminal,
When the destination is in the city, there is no need to dial the area code, which simplifies the dialing operation.

[0011] Further, since the dialing of the area code is not required, the contents of the dialing operation are the same as the case of making a local call from the wired terminal device, thereby using the mobile communication terminal device. In the case where a wired terminal is used and in the case where a wired terminal is used, it is not necessary to properly use the dial operation at the time of making a call, thereby making it possible to prevent erroneous operation and confusion.

In the mobile communication terminal device, the area code of the area where the mobile communication terminal device is located is displayed before dial input, so that the user can display the displayed area code before dial input. By looking at the area code, it is possible to confirm whether the dialing of the area code can be omitted. For this reason, it is possible to prevent the user from forgetting to enter the area code when it is necessary.

That is, first, when the terminal identification information (terminal ID number) is transmitted from the PHS terminals PS1 to PSk when the power is turned on or when the PHS terminals PS1 to PSk are transmitted, the location registration function transmits the terminal ID number to the PHS. The terminal ID number is transferred to the network PNW, and the terminal ID number is stored in the location registration memory in the PHS network PNW in association with the wireless areas E1 to En.

The location notification function is provided for each of the base stations BS11 to BS11.
PHS where BSnm exists in the wireless area formed by its own station
By transmitting the identification information (base station number) of the own station to the terminal periodically and at the time of incoming call, each PHS terminal PS1

Consists of

That is, radio frequency signals arriving from the base stations BS11 to BSnm are input to the radio unit 2 after being received by the antenna 1. In the radio unit 2, the received radio frequency signal is mixed with a reception local oscillation signal generated from a frequency synthesizer and frequency-converted into a reception intermediate frequency signal. The local oscillation frequency generated by the frequency synthesizer is specified by the control unit 10 according to the radio channel frequency. Further, the radio unit 2 is provided with a reception electric field strength detection unit. The reception field strength detection section detects the reception field strength of the radio frequency signal arriving from the base station BS, and notifies the control section 10 of the detected value.

The received intermediate frequency signal output from the radio unit 2 is input to a signal processing unit 3. The signal processing unit 3 has a demodulation unit, and the demodulation unit performs digital demodulation of the received intermediate frequency signal, thereby reproducing a digital communication signal. Also, the signal processing unit 3 is TD
It has an MA decoding unit. The TDMA decoding unit extracts a digital communication signal from a time slot assigned to itself, according to an instruction from the control unit 10, and inputs the extracted digital communication signal to the voice unit 4. The audio unit 4 includes an adaptive difference PCM codec and a PCM codec. The digital speech signal is sequentially decoded by the adaptive difference PCM codec and the PCM codec, and is reproduced as an analog speech signal. Then, the analog communication signal is amplified by the receiving amplifier and then output from the speaker 5 as loudspeaker.

On the other hand, the transmission voice input to the microphone 6 is transmitted by the PCM codec of the voice section 4 and the adaptive difference PC.
The signal is sequentially encoded by the M codec to be a digital communication signal. The signal processing unit 3 includes a TDMA encoding unit and a modulation unit. In the TDMA encoding unit, the digital communication signal output from the audio unit 4 is transmitted to the control unit 1.
It is inserted from 0 into the designated time slot and input to the modulation unit. In the modulation section, the carrier signal is digitally modulated by the digital communication signal, and the modulated carrier signal is input to the radio section 2. In the radio unit 2, the modulated carrier signal is mixed with a transmission local oscillation signal generated from a frequency synthesizer, thereby being frequency-converted to a radio channel frequency instructed by the control unit 10 and further transmitted at a predetermined transmission power level. Is amplified. The radio frequency signal output from the radio unit 2 is transmitted from the antenna 1 to the base station BS1 via the radio frequency switch.
1 to BS nm.

The control unit 10 uses a microcomputer, and includes a central processing unit (CPU) 11
An input / output port (I / O) 12 for connecting the radio unit 2, the signal processing unit 3, the audio unit 4, the sounder 7, the operation input unit 8 and the display unit 9 to the CPU 11,
3 and RAM 14, and the ROM 13 and RA
M14 and a bus 15 for connecting the CPU 11 to the M11.

The ROM 13 stores various control programs and control data necessary for the operation of the CPU 11, and includes a base station map, a control program for recognizing the presence area, and the like. And a control program for determining a destination and performing dial transmission control. FIG.
MO1 is an area for storing the base station map, MO2 is an area for storing a control program for recognizing the presence area, and MO3 is an area for storing a control program for destination determination and dial transmission. Are respectively shown. Here, the base station map is a map in which the area code data of the area where the base stations BS11 to BSnm exist is stored in advance in association with the base station numbers of the base stations BS11 to BSnm as shown in FIG. is there.

The RAM 14 is used to temporarily store data necessary for executing various controls in the CPU 11, for example, dial data and area code data of the area where the CPU 11 is located. FIG. 4 shows a memory map of the RAM 14, where MA1 is an increment of a dial data accommodation stack area, MA2 is an accommodation area of area code data of the area where the self is located, and MA3 is a search of the base station map MO1. Are shown, respectively.

The CPU 11 includes, in addition to ordinary control functions such as a wireless channel connection control for making and receiving calls and various controls during communication, an existence area recognition means 11a and a transmission area judgment means 11
b, and a dial transmission control means 11c based on the recognition and determination results of the presence area recognition means 11a and the transmission area determination means 11b.

The existence area recognizing means 11a searches the base station map stored in the ROM 13 when the base station number is notified from the base stations BS11 to BSnm during standby, and thereby determines the area where the self exists. Is recognized and stored in the RAM 14.

The transmission area determining means 11b determines whether the first digit of the dial data input from the dial keypad of the operation input unit 8 at the time of transmission is "0" or "1", or not. It is to determine whether the previous area is outside the city or inside the city.

The dial transmission control means 11c, when the transmission destination area is determined to be in the city by the transmission area determination means 11b, the area code which is recognized and stored by the existence area recognition means 11a. The data is read, added to the head position of the input dial data, and transmitted to the base stations BS11 to BSnm.

Next, the operation of the PHS terminals PS1 to PSk configured as described above will be described according to the control procedure of the CPU 11. 8 to 10 are flowcharts showing the control procedure of the control unit 10.

In the standby state, the CPU 11 monitors the arrival of the base station data in step 8c while monitoring the arrival of the incoming call and the operation of the transmission in steps 8a and 8b, respectively.

In this state, it is assumed that base station data has arrived from base stations BS11 to BSnm in the wireless area where the mobile station is located. The base station data is obtained by adding a header to a base station number as shown in FIG. 7, for example. When the base station data is received, the CPU 11 executes the area code update control. That is, as shown in FIG. 9, the CPU 11 first searches the base station map area MO1 based on the received base station number in step 9a,
At b, it is determined whether or not the corresponding base station number exists in the map area. If the corresponding base station number exists, the process proceeds to step 9c, where the corresponding area code data is read from the base station map area MO1, and the area code data is stored in the RAM 14 in step 9d. After writing to the area code data area, the system returns to the standby state.

As a result of searching the base station map area MO1, if the corresponding base station number does not exist, the flow shifts to step 9e where the local area number data area in the RAM 14 is stored in the own area code data area. After writing the code "FF" indicating that there is no external number data, the process returns to the standby state.

Now, in this state, it is assumed that the user has performed a dial input operation after an off-hook operation to make a call. Then, the CPU 11 executes dial data transmission control as follows. That is, the CPU 11
First, in step 10a, the dial button press data is read from the operation input unit 8, and in step 10b, it is determined whether or not the input data is the first digit data. If it is the first digit data, the process proceeds to step 10c, where the first digit data is “0” or “1”,
Alternatively, it is determined whether it is other than that. As a result of this determination, if the first digit is “0” or “1”, it is determined that the destination is a toll or a special number, and the process directly proceeds to step 10i. In this step 10i, the first digit dial button press data is stored in the base station B.
Send to S11-BSnm. The data of the second and subsequent digits of the dial button pressed continuously thereafter is transferred from step 10b to step 10i as it is, and transmitted to the base stations BS11 to BSnm.

On the other hand, suppose that the first digit of the dial button press data is other than "0" or "1". In this case, the CPU 11 determines that the call destination is in the city, and proceeds to step 10d, where the first digit dial button press data is temporarily stored in the stack MA1 of the RAM 14. Subsequently, the CPU 11 reads the area code data from the area code data area MA2 of the RAM 14 in step 10e, and stores the area code data as "F".
F ”is determined in step 10f.
If it is not F ", the read area code data is transmitted to the base stations BS11 to BSnm in step 10g. After transmitting the area code data, the process proceeds to step 10h, where the stack of the RAM 14 is first stored. And reads out the first digit dial button press data stored in the base station BS11 to BSnm in step 10i. The dial button press data after the first digit is directly transferred from step 10b to step 10i, where the base stations BS11-BSn
m.

Thus, when the destination area is the city, the dial data after the input local office number is added to the dial data shown in FIG.
The area code data is automatically added as shown in FIG.
Digitized dial data becomes base stations BS11 to BSnm
Sent to

If the area code data of the area where the user is located is "FF", that is, if the user is located in the wireless area of another system, the process directly proceeds from step 10f to step 10i, where it is executed. The inputted first digit button press data is transmitted to the base stations BS11 to BS.
out to nm.

As described above, in the present embodiment, each time a base station number periodically transmitted from the base stations BS11 to BSnm is received during standby, the base station map area MO1 is searched based on the base station number. Then, the area code data corresponding to the area where the user is located is read and stored in the RAM 14. When a dialing operation is performed in this state, it is determined whether the first digit of the dial push button data is "0" or "1" or any other value.
If it is other than "0" or "1", it is determined that the destination is in the city, the area code data is read from the RAM 14 and transmitted to the base stations BS11 to BSnm.
The dial push button data after the first digit input by the dial are sequentially transmitted to the base stations BS11 to BSnm.

Therefore, according to the present embodiment, if the area code is not dialed when calling the PHS terminals PS1 to PSk, it is determined that the call is for a local call, and is recognized in advance. The PHS terminals PS1
The area code of the area where PSk is located is automatically added to the input dial push button data and the base station BS11
~ BSnm. For this reason, even when making a call using the PHS terminals PS1 to PSk, the user does not need to dial the area code when the destination is in the city, which makes dialing easy. Become.

In addition, since the dialing of the area code is not required in the case of local call, the operation contents of the dial operation are the same as those in the case of local call from a wired telephone. When using PS1 to PSk and when using a wired telephone, it is possible to eliminate the necessity of properly using the dial operation when making a call, thereby preventing erroneous operation and confusion.

The present invention is not limited to the above embodiment. For example, in the above embodiment, the area code data recognized by the existence area recognition means 11a is stored in the RAM 1
4, the CPU 11 may control such that the recognized area code data is stored in the RAM 14 and displayed on the display unit 9. By doing so, the user can clearly see whether or not the caller is in the city by looking at the area code displayed on the display unit 9 prior to the dialing operation. It is possible to determine whether or not it is necessary to dial the station number.

In the above embodiment, the PHS terminal PS1
The case has been described in which the PHS terminals PS1 to PSk perform the recognition of the area code of the area where .about.PSk is present, the determination of whether the destination is in the city, and the dial transmission control when the destination is in the city. However, all of these controls may be performed in the base station.

That is, at the time of location registration of each PHS terminal,
The area code of the area where each PHS terminal exists is stored in a memory in the base station. When dial data arrives from the PHS terminal, the base station determines whether or not the received dial data includes an area code. If the result of this determination is that the area code is not included, it is determined that the call originates within the city and the PHS
The area code corresponding to the terminal is read from the memory, and the area code is added to the received dial data to add the area code to the PHS network P.
Transfer to NW.

With this configuration, the PHS terminal user can simplify the control program of the PHS terminal and provide the PHS terminal at a correspondingly low cost.

In addition, the configuration of the PHS terminal, the area code recognizing means, the destination determining means, the respective control procedures of the dial transmission control means based on the result of the determination, the control contents thereof, and the type of the mobile communication terminal (for example, In addition to a PHS telephone, a facsimile apparatus and a data terminal such as a personal computer are also included), and various modifications can be made without departing from the gist of the present invention.

[0044]

As described above in detail, in the mobile communication terminal of the present invention, the recognizing means for recognizing the area code of the area where the terminal is located based on the position information notified from the base station. Newly provided with a judging means for judging whether or not an area code is included in dial information of a communication partner inputted at the time of making a call, and a dial information sending control means operating according to the judgment result. I have. When the dial information transmission control means determines that the area code is not included by the determination means, the area code recognized by the recognition means is added to the input dial information. To the base station.

Further, in the base station apparatus of the present invention, the recognizing means for recognizing the area code of the area where the mobile communication terminal is located, based on the terminal identification information transmitted from the mobile communication terminal, A determination unit for determining whether the area information is included in the dial information of the communication partner transmitted from the communication terminal device and a dial information transfer control unit are newly provided.
