However, when the communication area of the wireless communication device is changed, the location registration information is not updated, so that there is a problem that the call cannot be received.

The present invention has been made in view of the above circumstances, and it is possible to promptly notify the user that he / she is out of the manually registered position (communication area), and a situation in which a call cannot be accepted. An object of the present invention is to provide a wireless communication device capable of reliably avoiding the above.

[0009]

According to the first aspect of the present invention,
In a wireless communication device that manually registers a position in each communication area of a communication network having a plurality of communication areas, a position information storage unit that stores position information corresponding to the manually-registered communication area, and the wireless communication device. The communication device is composed of a comparison means for comparing the position information in the communication area in which the communication device is currently located with the position information stored in the position information storage means, and a notification means for giving a notification when the comparison means detects a mismatch. There is.

Further, the invention of claim 2 is a radio communication device for connecting a plurality of base stations each having an independent communication area to a communication line network and for communicating with other terminal devices via these base stations. In the above, in the radio wave pulling-in means for pulling in the radio wave from the base station, the position registration requesting means for manually making a position registration request to the base station pulling in the radio wave by the radio wave pulling means, and the position registration requesting means. Position information storage means for storing the position information sent from the base station that is drawing the radio wave in response to the position registration request, and the position information and the position information included in the radio wave that is currently being drawn in by the radio wave drawing means. By comparing means for comparing with the position information stored in the storing means, and notifying means for notifying when the comparing means detects a mismatch Forms.

[0011]

As a result, according to the invention described in claim 1 or 2, the position registration information when the position is registered by the manual operation is compared with the position registration information in the communication area in which the current position is present, and the change occurs. When there is such a notification, the user can be notified that the position is out of the position at which the position was registered by manual operation, and the user can be prompted to update the position registration information.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a schematic configuration of a communication system to which the wireless communication device of the present invention is applied. In this case, 11, 12
, ... are base stations connected to a communication network (not shown), and these base stations 11, 12, ... Are arranged so that a predetermined range can be covered by respective communication areas 21, 22 ,. ing. Further, a plurality of communication areas (for example, communication areas 21, 22, ...) Form a paging area (bold solid line) for calling the wireless communication devices all at once.
Then, a predetermined communication area 2 of such a communication system
The wireless communication device according to the present invention is used for 1, 2 2, ...

FIG. 2 shows a schematic configuration of a manual location registration type PHS terminal used as such a wireless communication apparatus. In the figure, 11 is an antenna, and a transmitting / receiving device 12 is connected to this antenna 11. The transmitter / receiver 12 is composed of a frequency conversion unit and a modem. On the reception side of the frequency conversion unit, the signal input from the antenna 11 is input via an antenna switch that divides transmission / reception, and then from the PLL synthesizer. By mixing with the output local oscillation signal of a predetermined frequency, 1.
The frequency is converted from the 9 GHz band to an IF signal near 1 MHz.
On the other hand, on the transmission side, the modulated wave of π / 4 shift QPSK input from the modem is mixed with the local oscillation signal of a predetermined frequency output from the PLL synthesizer, so that 1.
The frequency is converted into the 9 GHz band, and the antenna 11 radiates the energy through the antenna switch.

Also, on the receiving side of the modem, the IF signal from the frequency conversion section is demodulated and separated into IQ data, which is transferred to the communication control section as a data string. On the other hand, on the transmission side, IQ data is generated from the data transferred from the communication control unit, modulated into π / 4 shift QPSK, and output to the frequency conversion unit.

A communication control unit 13 and a voice processing unit 14 are sequentially connected to the transmission / reception device 12, and a speaker 15 and a microphone 16 are connected to the voice processing unit 14.

Here, the communication control section 13 performs frame synchronization and slot data format processing. On the receiving side, data for one slot is received at a predetermined timing from the received data sent from the modem of the transmitting / receiving section 12. After extracting the unique word (synchronization signal) from this data to synchronize the frame and descramble the control data section and the audio data section, the control data is sent to the control section 17, which will be described later. The voice data is transferred to the voice processing unit 14. On the other hand, on the transmitting side, control data or the like is added to the voice data sent from the voice processing unit 14, a unique word or the like is added after scrambling, and transmission data for one slot is created at a predetermined timing. Then, it is inserted into a predetermined slot in the frame and sent to the modem of the transmitting / receiving unit 12.

The voice processing section 14 is composed of a speech codec and a PCM codec. Of these, the speech codec performs compression / expansion processing of digital data. On the receiving side, the ADPCM sent from the communication control section 13 is used. Audio signal (4bit x 8KHz = 32K
bps) is a PCM audio signal (8bit × 8KHz = 64Kbps)
) And decompress it to output to the PCM codec. On the other hand, on the transmission side, the PCM audio signal sent from the PCM codec is compressed by being encoded into an ADPCM audio signal and output to the communication control unit 13.

The PCM codec is an analog /
Digital conversion processing is performed. At the receiving side, the PCM audio signal sent from the speech codec is D / A.
The converted analog voice signal is output to the speaker 15.
On the other hand, on the transmitting side, the analog voice signal input from the microphone 16 is A / D converted and the PCM voice signal is output to the speech codec.

A control unit 17 is connected to the transmission / reception unit 12, the communication control unit 13, and the voice processing unit 14, and the control unit 17 includes a ROM 18, a RAM 19, and a key input unit 2.
0, the display unit 21 is connected.

In this case, the control unit 17 controls the entire apparatus according to a predetermined protocol.
7 has a CS-ID / paging area number detecting means 171 for detecting a base station ID (CS-ID) and a paging area number, and a location registration completion detecting means 172 for detecting completion of location registration.

The ROM 18 stores a control program for the control unit 17. The RAM 19 temporarily stores the data handled by the control of the control unit 17, and here, the base station ID as the location registration information.
(CS-ID) and paging area number are stored.

The key input unit 20 is for inputting a key input for setting each function to the control unit 17, and has a position registration key 201 for manually registering a position here. The display unit 21 displays input data and results for various controls.

Next, the operation of the embodiment thus constructed will be described. In this case, when the manual position registration mode is set, the flowchart shown in FIG. 3 is executed.

First, in step 201, the PHS terminal
It is determined whether the position registration has already been completed, that is, whether the position registration information has already been stored. Here, for example, when the power is just turned on and the location is not registered,
In step 202, it is determined whether the PHS terminal is currently in the communication range of any base station. In this case, PH
The determination as to whether the S terminal is within the range of the base station is made based on whether or not the radio wave (control channel) from the base station is successfully drawn.

The pulling in of the radio wave here is performed by the control unit 1.
Based on the pull-in period determined by 7, the control channel frequency assigned to each base station is searched at a predetermined timing. That is, in this case, when the control unit 17 receives the notification of the predetermined time, the transmission / reception device 12 and the communication control unit 13 are operated, and the local oscillation frequency output from the PLL synthesizer of the transmission / reception device 12 is changed. By doing so, the control channel assigned to each base station is pulled in,
If the control channel is successfully pulled, it is determined that one of the base stations is within the range, and if none of the control channels is pulled, it is determined that the base station is not within the range. . Here, if any of the base stations is out of the service area, the processing is ended as it is.

On the other hand, when it is determined that the radio wave from the base station has been successfully drawn in and the area is within the range, in step 203, the display unit 2
A message indicating that the vehicle is within the range is displayed in 1. And step 20
In 4, the position registration request signal is output to the base station by operating the position registration key 201 of the key input unit 20, and the position registration completion signal sent from the base station in response to the position registration request signal is sent to the control unit. The position registration completion detecting means 172 of 17 receives and judges the position registration completion.

Here, if the location registration is completed, the completion of the location registration is displayed on the display unit 21 in step 205, and the CS-ID / paging area number detection means 171 of the control unit 17 detects this point. The CS-ID or the paging area number, which is the position information of the base station in step 1, is detected, this is stored in the RAM 19, and the processing ends. The position information in this case is sent together with the position registration completion signal from the base station that has completed the position registration.

On the other hand, if it is determined in step 201 that the position has already been registered and the position information has already been stored in the RAM 19, the routine proceeds to step 206, where P is currently set.
Determine whether the HS terminal is within range of the base station. In this case, the determination as to whether or not the mobile station is within the range of the base station is made based on whether or not the radio wave (control channel) from the base station is successfully pulled in, as described above.

If the mobile station is not within the service area of the base station, the process proceeds to step 207, where the display section 21 indicates that the mobile station is out of service, and the location registration completion display is continued, and the process ends.

On the other hand, when it is determined in step 206 that the PHS terminal is within the range of the base station, the process proceeds to step 208. In step 208, the CS-ID of the control unit 17
The paging area number detecting means 171 detects the CS-ID or paging area number of the base station at this time, and the detected contents and the CS-ID of the base station stored in the RAM 19 at the time of the location registration previously performed. Alternatively, the CS stored in the RAM 19 is compared with the paging area number.
-Determine if the ID and paging area number have changed.

If there is no change, the location-registered base station has not changed at this point in time, and the call from the base station can be received as it is.
On the other hand, if there is a change in the CS-ID or paging area number stored in the RAM 19 as determined in step 208, the base station has moved to another paging area or paging area, and the current base station remains as it is. Since it is not possible to receive a call from, the display unit 21 displays that the location registration has not been completed in step 209, and the process ends.

Therefore, according to such an embodiment, the radio wave from the base station having an independent communication area connected to the communication network is drawn in, and the key input unit 20 is connected to the base station drawing the radio wave. The position registration key 201 is operated to make a position registration request, and the position information sent from the base station that is pulling the radio wave in response to the position registration request is stored in the RAM 19, and in this state, If the position information contained in the radio wave drawn from the base station in the communication area in which the present position is located is compared with the position information stored in the RAM 19, and if a mismatch is detected from the comparison result, the position-registered base station is detected. On the other hand, the display unit 21 displays a message indicating that the mobile terminal is currently within the range of another base station and cannot receive a call from the current base station as it is.
I am going to do it. As a result, it is possible to promptly inform the user that the position is out of the position at which the position was registered by manual operation, and to prompt the user to update the position registration information. You can surely avoid the situation that you cannot receive.

The present invention is not limited to the above-mentioned embodiments, but can be carried out by appropriately modifying it within the scope of the invention. For example, in the above-described embodiment, when the CS-ID and the paging area number stored in the RAM 19 are changed, only the position registration incomplete display is displayed on the display unit. You may make it sound a sound.

[0034]

As described above, according to the present invention, there is a change by comparing the position registration information when the position is registered by the manual operation with the position registration information in the communication area where the user is currently located. Since it is designed to notify when, it is possible to prompt the user to update the position registration information by promptly notifying the user that the position is out of the position when the position was registered by manual operation, As a result, it is possible to reliably avoid a situation where the call cannot be received.
