And are provided.

In the communication device of the present invention, when transmitting the position of the user to the other party, the position information obtained by the communication with the transmission line device is transmitted to the other party's device as user information by the transmitting means. This allows you to accurately position yourself
And you can tell the other person automatically. On the other hand, when the location information is sent from the other party, this location information is
After being received by the receiving means, it is output by the output means. Thereby, the position of the other party can be known.

[0007]

Embodiments of the present invention will be described below in detail with reference to the drawings.

[First Embodiment] [Outline of First Embodiment] First, an outline of the present embodiment will be described.

(1) In the present embodiment, the communication device of the present invention is used as a mobile communication terminal of a mobile communication system in which a communication area is divided into a plurality of cells and communication is performed for each cell.

That is, in the mobile communication system,
In order to reduce transmission power and effectively use frequencies, a communication area is usually divided into a plurality of cells, and communication is performed for each cell. In the present embodiment, the communication device of the present invention is used as a mobile terminal device of such a mobile communication system. In this case, the communication of each communication device is performed via the base station provided in the cell in which the communication device is located. When the communication is provided as a service by the communication carrier, such as when the mobile communication system is a simple mobile phone system (hereinafter referred to as “PHS”), the communication area corresponds to the service area.

(2) In the present embodiment, the communication device of the present invention is used as a mobile terminal device of a mobile communication system having a location registration function.

That is, in a mobile communication system in which a communication area is divided into a plurality of cells, when a paging for calling a communication device having an incoming call is performed, one or a plurality of cells are not called in the entire communication area. It can be performed in cell units. However, in order to realize this, it is necessary for a transmission line device (for example, a device that forms a communication network) that forms a transmission line of a mobile communication system to always know the location area of the communication device.

Therefore, in such a mobile communication system, the communication area is usually divided into a plurality of location registration areas each including one or a plurality of cells, and the location registration area in which each communication apparatus is located is defined by each communication apparatus. A location registration function for registering as a location area is provided. With such a configuration, when an incoming call is received by a certain communication device, the area where this communication device is located is determined by determining the location registration area where this communication device is located based on the registration information of this communication device. You can make a general call only with. In the present embodiment, the communication device of the present invention is used as a mobile terminal device of such a mobile communication system.

(3) Further, in the present embodiment, position registration is performed as position information that is information obtained by communication with a transmission line device that forms a transmission line and that can indicate the position of the own device. The identification information of the location registration area obtained by communication with the database device for use is used.

(4) Further, in the present embodiment, when transmitting position information, this is transmitted not as control information but as user information. This is to enable the communication device of the present embodiment to use an existing mobile communication system as a mobile terminal device.

(5) Further, in the present embodiment, when the position information is provided to the user, the position information is converted from the identification information of the position registration area to the address information and provided. This is to provide the position information to the user in a form that is as easy to understand as possible.

(6) Further, the communication device of the present embodiment is configured as a composite device capable of coping with a plurality of communication systems having different cell sizes. That is, it is configured as a compound device that can handle a plurality of mobile communication systems having different zone sizes. This is to cope with the difference in moving speed of the communication device. In other words, this is to cope with both walking and moving vehicles.

In the following description, as a plurality of mobile communication systems having different zone sizes, a case where a PHS of a minimal zone system and a radio paging system of a large zone system are used will be described as a representative. At present, the Japanese radio calling system is a one-way type system.
On the other hand, the communication device of the present embodiment is a bidirectional device. Therefore, at this stage, the communication device of the present embodiment cannot be used as a mobile terminal device of the radio paging system. However, in the future, the Japanese radio paging system may be a two-way system like the North American radio paging system. Therefore, in the future, it is considered that the communication device of this embodiment can be used as a mobile terminal device of a Japanese radio paging system. Therefore, in the present embodiment, a radio paging system is used as one of the mobile communication systems.

(7) In this embodiment, not only position information but also a message is transmitted as user information. Here, the message means information represented by at least one of letters, numbers and symbols, unlike the voice information and the image information. This is to provide an inexpensive communication device.

That is, when voice information is transmitted as user information (when making a call), a voice information encoder / decoder is required, which increases the manufacturing cost of the communication device. On the other hand, when transmitting a message, a coding / decoding device is not required, so that the manufacturing cost of the communication device is reduced. This embodiment focuses on this point and transmits a message as user information.

(8) Further, in the present embodiment, when user information is received, affirmative response information (hereinafter referred to as “ACK information”) indicating that is sent back to the sender. This is because the message is transmitted as user information.

That is, in the configuration of transmitting a message as the user information, unlike the case of transmitting the voice information (when making a call), it is not known whether or not the user information has reached the other party. In the present embodiment, attention is paid to this point, and when user information is received from another device, ACK information is returned to the transmission source to notify the transmission source that the user information has been received. There is.

(9) Further, in the present embodiment, ACK
When the information is returned, the position information of the device itself is returned together with the ACK information. The identification information of the location registration area obtained by the location registration process is also used as the location information in this case.

(10) Further, in this embodiment, a direct optical communication function using a wireless transmission path is provided. The reason why direct communication is realized by light instead of radio waves is to avoid restrictions of the Radio Law and the like as much as possible.

That is, in order to expand the range of direct communication, it is preferable to realize communication by radio waves. But,
If this is done, the restrictions of the Radio Law and the like will increase. Therefore, in this embodiment, the direct communication by light is adopted to avoid the restrictions of the Radio Law and the like as much as possible. In such a configuration, direct communication is
Limited to the range in which the other person can see. The above is the outline of the present embodiment.

The transmitting / receiving antenna 123 of the communication unit 12 is provided inside the communication device.

[Operation of One Embodiment] (1) First, the operation from turning on the power switch 16 to turning off the switch 16 will be described.

When the user turns on the power switch 16, the communication device is turned on. When the communication device is turned on, first, the location registration process is executed. This location registration process is performed as follows, for example. That is, when the communication device is set to the ON state, first,
It is determined whether the position information reported from the base station and the position information held in the position information holding unit 20 match. As a result, it is determined whether or not the position registration area where the mobile communication device is currently located and the position registration area indicated by the position information held by the position information holding unit 20 match.

If the two match, the communication device does nothing. On the other hand, if they do not match, the communication device transmits a position registration signal to the base station. As a result, the position information of the communication device registered on the communication network side is rewritten. Next, the communication device writes new position information in the position information holding unit 20. With the above, the position registration process is completed. In this location registration processing, location registration processing on the PHS side and location registration processing on the radio calling system side are executed. These are sequentially executed in a predetermined order.

When the location registration process is completed, the mobile communication device enters the standby mode. In this standby mode,
When the user performs a calling operation, the communication device executes a calling process. On the other hand, when there is an incoming call from another communication device, the communication device executes an incoming call process. Further, when moving from one cell to another cell, the communication device again executes the above-mentioned location registration process. After that, when the power switch 16 is set to the off state, the communication device is also set to the off state.

The above is the operation from turning on the power switch 16 to turning off the switch 16.

(2) Next, a procedure for transmitting user information from a certain communication device to another communication device via the PHS transmission path will be described.

FIG. 4 is a diagram for explaining this procedure. In the figure, A and B represent communication devices, MS represents a micro cell, E represents a location registration area, and BS.
Indicates a base station, and NW indicates a communication network. It should be noted that FIG. 4 shows a procedure for transmitting user information from the communication device A to the communication device B. Further, FIG. 4 shows a case where the communication devices A and B are present in different microcells MS (A) and MS (B) as a representative. Furthermore, in FIG. 4, the location registration area E in which the microcells MS (A) and MS (B) are different is shown.
(A) and E (B) are shown as representatives.

In this case, first, from the communication device A to the base station B of the microcell MS (A) in which the communication device A is located.
The user information UI (A) is transmitted to S (A) ().
The user information UI (A) is composed of a message and position information of the communication device A, as shown in FIG. However, the message is inserted only when the user desires. The location information is the location registration area E (A) where the communication device A is located.
It is represented by the identification information of. This user information UI (A)
Are transmitted by being divided into a plurality of information channels TCH. FIG. 6 is a diagram showing a configuration of a communication physical slot in which an information channel TCH used for transmitting the user information UI (A) is set. In the figure, CI indicates a channel type, SA indicates a low speed associated control channel, TC
H indicates an information channel, and CRC indicates a cyclic generation code.

The user information UI (A) transmitted to the base station BS (A) is supplied to the communication network NW (). The user information UI (A) supplied to the communication network NW is the communication device B.
Base station BS (B) of the microcell MS (B) in which
Supplied to (). The user information UI (A) supplied to the base station BS (B) is supplied to the communication device B using the information channel TCH (). As a result, the communication device A
Message and position information have been supplied to the communication device B.

When the communication device B receives the user information UI (A), the communication device B transmits the user information UI (B) to the base station BS (B) (). This user information U
I (B) is user information UI (B) as shown in FIG.
Is composed of ACK information and position information of the communication device B. The position information of the communication device B is represented by the identification information of the position registration area E (B) in which the communication device B is located. This user information UI (B) is divided into a plurality of information channels TCH and transmitted.

The user information UI (B) transmitted to the base station BS (B) is supplied to the communication network NW (). The user information UI (B) supplied to the communication network NW is the base station BS
() Is supplied to (A). The user information UI (B) supplied to the base station BS (A) is supplied to the communication device A using the information channel TCH (). As a result, the ACK information is returned to the communication device A, and the position information of the communication device B is supplied.

The above is the procedure for transmitting user information from one communication device A to another communication device B via the PHS transmission path. Although detailed description is omitted, when user information is transmitted from a certain communication device A to another communication device B via a transmission line of the radio paging system, the transmission is performed in substantially the same procedure.

(3) Next, a procedure for transmitting user information from one communication device to another communication device by using optical communication will be described.

FIG. 8 is a diagram showing this procedure. In addition,
FIG. 8 shows a case where the user information is transmitted from the communication device A to the communication device B as a representative. This communication is performed by the communication device A.
Is performed within a range where the communication device B can be seen. In addition, this communication is performed with the light emitting unit 133 of the communication device A facing the communication device B. This is because the communication between the two is performed using light via the wireless transmission path.

In this case, the communication device A uses the user information UI.
(A) is sent (). This user information UI (A)
Is composed of an encryption key and a message, as shown in FIG. As the encryption key, for example, a part of the selection number given to the communication device B, for example, the last four digits is used.

The user information UI (A) is supplied to the communication device B via the wireless transmission path. When the communication device B receives the user information UI (A), the communication device B receives the user information UI (A).
It is determined whether or not the encryption key included in (A) matches the encryption key held by itself (the lower four digits of the selection number of the device itself). When they match, the user information UI (A) is fetched. As a result, the message of the communication device A is supplied to the communication device B.

After that, the communication device B displays the user information UI.
(B) is output. This user information UI (B) is shown in FIG.
As shown in 0, it is composed of an encryption key (lower four digits of the selection number of the communication device A) and ACK information. The user information UI (B) is supplied to the communication device A via a wireless transmission path. When the communication device A receives this user information UI (B), the encryption key contained in this user information UI (B) and the encryption key held by itself (the lower four digits of the selection number of its own device) are It is determined whether or not they match, and the user information UI (B) is fetched only when they match. This allows
This means that the ACK information has been returned to the communication device A.

The above is the procedure for transmitting user information from one communication device A to another communication device B by optical communication.

(4) Next, a user's calling operation when a certain communication device makes a call via the transmission path of the PHS will be described.

FIG. 11 is a flowchart showing this calling operation. In this operation, the user first instructs the communication device to set the transmission mode on the PHS side (step S11). This instruction is given by operating the transmission mode setting switch 17. Next, the user inputs a message for transmission (step S1).
2). This input is performed by operating the input unit 14. However, this input is performed only when sending a message. That is, without sending a message,
When transmitting only the location information, this input is not made.

Next, the user inputs the selection number of the destination (step S13). This input is performed by operating the input unit 14. Next, the user gives an instruction to prohibit the transmission of the position information (step S14). This instruction is given by operating the position transmission prohibiting switch 20. However, this instruction is issued only when the position information is not transmitted. Next, the user instructs the communication device to make a call (step S15). This instruction is given by turning on the transmission switch 18.

The above is the user's calling operation when a certain communication device makes a call via the PHS transmission path. Although a detailed description is omitted, when a certain communication device makes a call via the transmission line of the radio calling system, the user's call operation is performed in substantially the same manner.

(5) Next, the processing of the control unit 26 when a certain communication device makes a call via the transmission path of the PHS will be described.

12 and 13 are flowcharts showing this processing. Note that FIG. 12 shows a part of this processing, and FIG. 13 shows the remaining part. The illustrated process is started when the user instructs the setting of the transmission mode. In this process, the control unit 26 first switches the communication units 12 and 13 from the on state to the off state (step S21). This prohibits outgoing calls and incoming calls from the communication units 12 and 13. Next, the control unit 26 determines whether a message has been input by the user (step S22).

When a message is input, the control unit 2
6 stores the input message in the buffer (step S23). Next, the control unit 26 determines whether or not the user has instructed to make a call (step S24).
That is, it is determined whether the transmission switch 18 is set to the ON state. On the other hand, when the message is not input, the control unit 26 does not perform the message storage process and determines whether or not the transmission is instructed (step S24).

When an instruction to make a call is issued, the control section 26
A process for establishing a link channel is executed (step S25). As a result, control information can be transmitted / received to / from the base station of the micro cell in which the own device is located.
Next, the control unit 26 executes a process for establishing a service channel (step S26). This process is performed using the link channel. As a result, user information can be transmitted / received to / from the base station of the microcell in which the own device is located.

Next, the control unit 26 determines whether or not a message is stored in the buffer (step S2).
7). When the message is stored, the control unit 26
Determines whether or not the user has instructed to prohibit the transmission of position information (step S28). That is, it is determined whether or not the position sending prohibiting switch 20 is set to the on state. If not instructed, the control unit 26 supplies the message and the position information held in the position information holding unit 20 to the communication unit 11 (step S29). As a result, the message and the position information are transmitted to the baseband circuit unit 111.
Is transmitted from the transmission / reception antenna 113 via the wireless circuit unit 112.

On the other hand, when the prohibition of the transmission of the position information is instructed, the control unit 26 supplies only the message to the communication unit 11 (step S31). Thus, in this case, only the message is sent. If it is determined in step S27 that the message is not stored, the control unit 26 sends only the position information to the communication unit 11.
To supply. Accordingly, in this case, only the position information is transmitted to the destination. In this case, it is not determined whether or not the position information transmission prohibition instruction has been issued. That is, even though no message has been input, the transmission instruction has been issued means that only the position information is transmitted. Because it does.

When the supply of information to the communication section 11 is completed, the control section 26 determines whether or not the ACK information is received (step S32). If received, it is determined whether or not the received information includes position information (step S33). When the position information is included, the position information is converted from the identification information of the position registration area into the address information (step S34). This conversion is performed using the conversion table stored in the conversion table storage unit 24. Next, the control unit 26 supplies the position information converted from the ACK information to the display unit 15 (step S35). Thereby, the ACK information and the position information are displayed. As a result, the user can know that the message or the like has been reliably received at the destination and the position of the destination.

On the other hand, when the position information is not included, the control unit 26 does not perform the position information conversion process and A
Only CK information is supplied to the display unit 15 (step S3
6). Thereby, in this case, only the ACK information is displayed. As a result, the user can only know that the message was received. Note that the above step S3
When it is determined in 2 that the ACK information is not received, the control unit 26 supplies negative acknowledgment information (hereinafter referred to as “NACK information”) to the display unit 15 (step S37). As a result, in this case, only NACK information is displayed. As a result, the user can know that the message or the like was not received at the transmission destination.

When the supply of information to the display unit 15 is completed, the control unit 26 executes the process of releasing the wireless channel (link channel and service channel) (step S38). Next, the control unit 26 returns the communication units 12 and 13 from the off state to the on state (step S39). This allows the communication units 12 and 13 to make and receive calls. As a result, the communication device returns to the standby mode.

FIG. 14 is a diagram showing an example of the conversion table stored in the conversion table storage unit 24. As shown in the figure, the conversion table holds the identification information of the location registration area and the address information of the location registration area in a corresponding manner. As the address information of the position registration area, for example, address information near the central position of the position registration area is used. This address information is registered in advance by the user or the seller of the communication device.

The above is the processing of the control unit 26 when a certain communication device makes a call via the PHS communication network. Although a detailed description is omitted, the control unit 26 performs the same process when a certain communication device makes a call via the communication network of the radio calling system.

(6) Next, the processing of the control unit 26 when a certain communication device receives an incoming call via the PHS communication network will be described.

15 and 16 are flowcharts showing this processing. Note that FIG. 15 shows a part of this processing, and FIG. 16 shows the remaining part. The illustrated process is started when the device receives an incoming call through the PHS transmission path. In this process, the control unit 26 first
The communication units 12 and 13 are switched from the on state to the off state (step S41). This prohibits outgoing calls and incoming calls from the communication units 12 and 13. Next, the control unit 26 sequentially executes the link channel establishing process and the service channel establishing process (steps S42 and S43). This allows
User information can be transmitted and received to and from the base station. As a result, the user information sent from the base station is supplied to the control unit 26 via the transmitting / receiving antenna 113, the wireless circuit unit 112, and the baseband circuit unit 111.

Next, the control section 26 sounds the ringer 22 (step S44). As a result, the user is notified that an incoming call has been received. Next, the control unit 26 determines whether or not automatic storage is instructed by the user (step S45). That is, it is determined whether or not the automatic storage instruction switch 19 is set to the on state. If not instructed, the control unit 26 determines whether or not the position information is included in the user information received via the service channel (step S46). When the position information is included, the position information is converted from the identification information of the position registration area into the address information (step S47). This conversion is
This is performed using the conversion table stored in the conversion table storage unit 24.

Next, the control unit 26 determines whether or not the received information includes a message (step S4).
