The above is a description of the configurations of the mobile communication system and main devices according to the present invention.

As the mobile communication system, PDC,
Any mobile communication system such as W-CDMA and CDMA2000 can be adopted, and a base station, a base station controller,
The switching device and the like are not limited to the ground fixed station, but may be modified, for example, by mounting each function on an artificial satellite and wirelessly connecting each other.

A communication method for realizing a plurality of services using this mobile communication system will be described in detail below. (1) Waiting Notification Service An example will be described in which the user A carries the mobile station 1 and the user B carries the mobile station 2, and the user A and the user B make a meeting.

FIG. 4 is a diagram showing a communication sequence when the waiting notification service is implemented.

The user A operates the operation button of the operation unit 17 of his / her mobile station 1 at the meeting place. Then, the control unit 15 reads the identification information ID2 (telephone number, mail address, etc.) of the mobile station 2 of the user B stored in the storage unit 18, and displays it on the display unit 16. In this situation, when the user presses a predetermined button on the operation unit 17 (performs a predetermined operation), the control unit 15 causes the identification information I displayed.
D2 is temporarily held, the first wireless transmission / reception unit 13 is controlled to calculate the position information of the own station, and the position information P1 (for example, latitude X, longitude Y) of the own station, which is the calculation result, is transmitted to the first wireless. Obtain from the transmitter / receiver.

Then, the control unit 15 reads out the identification information ID1 (telephone number, mail address, etc.) of the own station from the storage unit 18, and includes the acquired position information P1 and the identification information ID2 of the other mobile station which is held. A service registration message is generated and the second wireless transmission / reception unit 14 is controlled to transmit this service registration message to the base station 3 by a wireless signal. Under the control of the control unit 17, the second wireless transmission / reception unit 14 transmits the service registration message from the antenna 12 as a wireless signal.

In the above operation, it is preferable that the user A operates the operation unit 17 to input the waiting time information, and the control unit 17 includes the inputted waiting time information in the service registration message. .

The base station 3 receives a radio signal from the mobile station 1 by means of an antenna (not shown) and sends a service registration message to the switching device 7 via the base station control device.

Upon receiving the service registration message, the switching device 7 registers (stores) information such as message contents ID1, ID2, P1 and T in the service management table of the database 73 under the control of the control unit 72.

Here, the service registration table will be briefly described. Specifically, it is preferable to use the service registration table shown in FIG.

The service registration table includes request source mobile station identification information, request source mobile station position information, partner mobile station identification information,
It is a table for managing the location information of the partner mobile station, the waiting time, and the like. In this embodiment, in the table, "ID1", "P1", "ID2", and "T" are arranged in order.
Will be stored.

Now, when the registration in the service registration table is completed, or in parallel with the registration process, the exchange 7 searches for the position symbol (S) based on the position information P1.

The search for the position symbol (S) will be briefly described.

The control unit 72 of the exchange apparatus 7 stores position symbol information in the database 73 in association with the coordinate position information (the name of the building, the image, or the name of the building which serves as a mark of the meeting place existing at the coordinate position). (Name, image, etc.) is stored. That is, the position symbol management table shown in FIG. 6 stores the position symbol information in association with the coordinate position (latitude, longitude).

Therefore, the control unit 72 specifies the position symbol S at the position closest to P1. It should be noted that since the view and the degree of crowding around each position symbol are different, the identification range (L) is further stored for each position symbol, and the distance between the position P1 and the position of the position symbol is within the identification range, It is more preferable to specify a position symbol close to the position P1. That is, in the above search, if the distance between P1 and the position of the position symbol is more than a predetermined value (L (m)), that symbol is not adopted. This is because there is a high possibility that the user B cannot meet even if he or she aims for the position symbol.

Now, the exchange device 7 that has searched for the position symbol
The control unit 72 generates a service notification message including the identification information ID1 of the mobile station 1 as the service request source, the position information P1, the position symbol S obtained by the search, and the waiting time T, and transmits the service notification message via the base station 5. It transmits to the mobile station 2.

Upon receiving the radio signal from the base station 5, the control unit 15 of the mobile station 2 which has received the service notification message causes the display unit 16 to display the information of ID1, S, P1 and T, and , Displays a message prompting you to select whether to approve the start of the waiting service.

When the user B approves the start of the service by operating the operation unit 17, the control unit 15
Detects the operation and sends an approval message to the exchange 7.

When the switching device 7 receives the approval message, the switching device 7 transmits the approval message to the mobile station 1, and when the mobile station 1 receives the approval message, the control unit 15 controls
A message indicating that the service is started is displayed on the display unit 16.

In the mobile station 2 which has been subjected to the approval operation, the control unit 15 then controls the first wireless transmission / reception unit 13 to periodically acquire the position information P2 of the own station and exchange position messages. Send to device 7. It is desirable that the position message include information such as identification information ID1 and ID2 in addition to the position information P2 detected by the first wireless transmission / reception unit 13.

The control unit 72 of the exchange apparatus 7 specifies the target service registration table based on ID1 and ID2 included in the received position message, and the mobile station P2 also included in the position message in the partner mobile station position information. Register (memorize) the information of. It should be noted that P1 is a meeting place and does not change unless changed by the user A of the mobile station 1 or the like, but since P2 changes from moment to moment as the mobile station 2 moves, the control unit 72 of the exchange apparatus 7 It is updated each time the mobile station location information of the other party is received.

When the control unit 72 of the exchange apparatus 7 detects that the received P2 satisfies the following predetermined condition, it sends a detection notification message to the mobile station 1.

Examples of predetermined conditions Condition 1: P1 and P2 match Condition 2: Distance between P1 and P2 is within a predetermined distance Condition 3: P2 is the identification range (L) from the position of the position symbol
It is preferable to perform the detection based on any one of the above conditions.

Upon receipt of the detection notification message, the control unit 15 of the mobile station 1 causes the display unit 16 to display that the mobile station 2 has approached the meeting place.

As a result, the user A of the mobile station 1 and the user B of the mobile station B can meet.

Further, according to the conditions 2 and 3, it can be seen that the meeting partner has approached the vicinity of the meeting place.
Even if the user A who has requested this service waits at a coffee shop or the like near the meeting place, the notification by the service prevents the user A from waiting.

When the switching device 7 does not detect that the condition is satisfied even after the waiting time has passed, the switching device 7 clears the contents of the service registration table relating to the waiting and notifies the mobile station 1 of the end of the service. Preferably, the mobile station 1 or 2 is transmitted with a message notifying that either or both of them have exceeded the waiting time.

Next, a modification of this embodiment will be described. In the embodiment described above, the switching device 7 searches for the position symbol, but the position symbol approval message including the searched position symbol S can be transmitted to the mobile station 1 via the base station 3. Then, the control unit 15 of the mobile station 1 causes the display unit 16 to display the received position symbol S (preferably also the image of the position symbol). Then, the display unit 16 displays a message to select whether to approve the position symbol.

Here, the user A operates the operation unit 17,
When the approval is selected, the control unit 15 detects the selection and transmits a position symbol approval message to the exchange 7. The control unit 72 of the exchange apparatus 7 transmits the service notification message (including the image of the position symbol) to the mobile station 2 on the condition that this message is received.

On the other hand, when the approval / denial is selected in the mobile station 1, the control unit 15 of the mobile station 1 transmits a position symbol approval / denial message to the exchange 7. The control unit 72 of the exchange 7 receives the message and receives the message.
The service notification message not including the position symbol S is transmitted to.

The subsequent processing is the same as the processing sequence described with reference to FIG. In another modified example, in the above-described embodiment and modified example, a small camera for shooting is attached to the mobile station 1, and the user A operates the operation unit 16 to shoot the scenery of the meeting place with this small camera. At that time, the control unit 15 controls the first wireless transmission / reception unit 13 to acquire the position of the mobile station 1 at the time of shooting. Then, the control unit 15 stores the image data F obtained by photographing and the acquired position in the storage unit 18 in association with each other.

Then, the service registration message in FIG. 4 is transmitted including the captured image data G. Then, the service notification message is also transmitted including the image data G, and under the control of the control unit 15, the captured image of the waiting place is displayed on the display unit 16 of the mobile station 2.

As a result, it becomes easier for the user B to specify the meeting place.

The mobile station 1 stores the image data G and the information on the position of the photographing location in association with each other. Therefore, in the next meeting, the user A operates the operation unit 17 to display the image data G and the position stored under the control of the control unit 15 on the display unit 16 and send it as a service registration message ( When a plurality of image data G are stored, the selected image data G and its position can be displayed and transmitted according to the selection operation using the operation unit 16 of the user A). And the exchange device 7
Also, the image data G selected as the service notification message is transmitted.

As a result, the user A himself / herself can meet by selecting the meeting place using the past data without going to the meeting place. In another modification, the service notification message does not include the contents P1, S, T, etc., but the access destination (here, for example, the switching device 7) information, and the user A of the mobile station 2 is notified. The operation unit 16 is operated so as to access the access destination. Then, the switching device 7 may query the mobile station 2 for information such as P1 and T from the database 73. (2) Mutual approach notification service When the mobile station 1 is installed in the car A on which the user A is mounted and the mobile station 2 is installed on the car B on which the user B is mounted, the cars A and B are used for driving. An example will be described.
FIG. 7 is a diagram showing a communication sequence when the mutual approach notification service is implemented.

The user A operates the operation button of the operation unit 17 of his / her mobile station 1 at the meeting place. Then, the control unit 15 reads the identification information ID2 (telephone number, mail address, etc.) of the mobile station 2 of the user B stored in the storage unit 18, and displays it on the display unit 16. Then, the user A further specifies the position N (latitude, longitude information) of the destination by operating the operation unit 16. In this situation, when the user presses a predetermined button on the operation unit 17 (performs a predetermined operation),
The control unit 15 detects this and reads the identification information ID1 (telephone number, mail address, etc.) of the own station from the storage unit 18, and includes the identification information ID1, the destination position N, and the identification information ID2 of the partner mobile station. Generate a service registration message,
The second wireless transmission / reception unit 14 is controlled to transmit this service registration message to the base station 3 by a wireless signal.

By this control, the second radio transmitter / receiver 14
The service registration message is transmitted from the antenna 12 as a wireless signal.

The base station 3 receives this radio signal via the antenna and transmits a service registration message to the switching device 7 via the base station control device.

Upon receiving the service registration message, the exchange 7 registers (stores) information such as message contents ID1, ID2, N in the service management table of the database 73 under the control of the controller 72.

The service registration table will be briefly described. FIG. 5 shows the contents of the service registration table.

The service registration table is provided with areas for storing requester mobile station identification information, destination position information, partner mobile station identification information, waiting time, and the like. Furthermore, request source mobile station identification information, partner mobile information. An area for storing the positional information notified in association with the station identification information is also provided.

In this embodiment, upon receipt of the service registration message, "ID1", "N",
“ID2” will be stored.

Now, the control unit 72 of the exchange apparatus 7 which has registered the service management table sends a service notification including the identification information ID1 of the mobile station 1 that requested the service, the position N of the destination, and the identification information ID2 of the partner mobile station. A message is generated and transmitted to the mobile station 2 via the base station 5.

The control unit 15 of the mobile station 2 which has received the service notification message by receiving the radio signal from the base station 5 causes the display unit 16 to display the information of ID1 and N and starts the waiting service. Display a message prompting you to approve or not.

When the user B approves the service start by operating the operation unit 17, the control unit 15
Detects the operation and sends an approval message to the exchange 7.

Upon receiving the approval message, the exchange 7 sends the approval message to the mobile station 1. When the mobile station 1 receives the approval message, the display of the service start is displayed on the display unit 16 under the control of the control unit 15.
As a result, the user A can recognize that the registration has been completed normally and the partner has also agreed.

When the approval operation is performed, the control unit 15 of the mobile station 2 periodically controls the first wireless transmission / reception unit 13 to acquire the position P2 of the own station, and the second wireless transmission / reception unit 14 By controlling the position P2 and the identification information ID2 of the own station.
A position message including the is transmitted by a wireless signal. The base station 5 receives this and gives a position message to the switching device 7.

When the switching device 7 receives the position message, it outputs P as position information corresponding to ID2 of the service registration table managed by the database 73 described above.
2 (latitude X2, longitude Y2) is stored. Preferably, the reception (or storage) time is also stored together with the storage of the position information.

Similarly, in the mobile station 1, after receiving the approval message, the control unit 15 periodically causes the first wireless transmission / reception unit 13 to operate.
By controlling the second wireless transmission / reception unit 14 by acquiring the position P1 of the own station at that time and transmitting the position message including the position P1 and the identification information ID1 of the own station by a wireless signal. When the base station 3 receives this and gives the position message to the switching device 7, the switching device 7 receives the position message, and P1 is set as the position information corresponding to ID1 of the service registration table managed by the database 73 described above. (Latitude X2, longitude Y2) is stored. Preferably, the storage time is also stored together with the storage of the position information.

Therefore, the exchange 7 sequentially updates the position information P1 and P2 in the database 73.

Further, the exchange device 7 stores the position information in this way, but separately, the control unit 72 performs a calculation for obtaining the distance between the stored position information P1 and P2.

Then, according to the result of the calculation, the control section 72
When it is detected that the distance is a predetermined distance (L) or more, the separation notification message is transmitted to each of the mobile stations 1 and 2.

When the mobile stations 1 and 2 receive the separation notification message, the respective control units 15 display a separation alarm on the display unit 16. Alternatively, predetermined light and sound are generated from a light emitting unit and a speaker (not shown).

As a result, the users A and B can recognize that the speeds of the automobiles A and B need to be adjusted, respectively.

When it is detected that the distance is within the predetermined distance (L), the control unit 72 of the exchange apparatus sends not the separation notice message but the area notice message to the mobile stations 1 and 2, respectively. Is desirable. Mobile station 1, 2
Upon receipt of the in-range notification message, each control unit 15 detects it and outputs and displays it on the display unit 16, the light emitting unit, the speaker, etc. that the partner mobile station and the own station are within the predetermined distance.

In the above-described embodiment, preferably, the above-mentioned calculation is the position information P1 stored in the service registration table,
If the time difference is equal to or more than a predetermined time by referring to the time when P2 is stored, the separation notification message is not transmitted. Alternatively, the position unupdated message is transmitted to the mobile station corresponding to the position information whose time is older. Of course, this position unupdated message may be transmitted to the mobile station when the difference between the current time and the reception time (stored time) when the position information is received becomes a predetermined time or more.

A modification of this embodiment will be described below. The switching device 7 refers to the destination position N when transmitting the separation notification message, and refers to the position P of the mobile station 1.
1 and the position P2 of the mobile station are used to calculate the rank relationship of the distance from the destination (for example, if the mobile station 2 is closer, first: mobile station 1, second: mobile station 2, etc.) and calculate the rank relationship. Information (for example, first: mobile station 1, second: mobile station 2, etc.) is notified to at least one mobile station. For example, if the mobile station 1 is closer to the destination, the information “ID1 ahead” is transmitted.

In the mobile stations 1 and 2, if this station uses this information, if the station is closer to the destination (for example, if the station is the first one), "the station is too far ahead", the own station will If it is far from the destination (for example, if its own station is later), a message is displayed, such as "I'm late", which is an indicator of whether to speed up or slow down. Of course, a light emitting unit and a speaker (not shown) may be used to perform different light emission and sound output depending on whether the speed should be increased or decreased.

The mobile stations 1 and 2 or the switching device 7 are
When it is determined that the own station has reached the destination by using 1, P2, and N, it is desirable not to transmit the position message. For example, when the mobile stations 1 and 2 detect the arrival, the arrival message is transmitted to the exchange 7 and the position message is not transmitted thereafter. Further, when the exchange 7 makes a determination, it transmits a position message transmission end message to the arriving mobile station. The mobile station receiving the transmission end message stops transmitting the position message thereafter. It is desirable to automatically notify the mobile station on the non-arrival side of the arrival from the mobile station or the switching device 7 that has detected the arrival. By this notification, the arrival of the partner mobile station can be detected on the side of the mobile station which has not reached yet. (3) Collective movement support service Plural persons (here, users A, B,
An example will be described in which three people, C, move together while moving (for example, going on an excursion).

The user A is a person who has a role of managing so that someone is not separated during the movement, and the users B and C are those who are managed in reverse.

FIG. 9 is a diagram showing a communication sequence at the time of carrying out the collective movement support service in such a case.

First, the user A who is the user of the mobile station 1
Operates the operation button of the operation unit 17 of its own mobile station 1.
Then, the control unit 15 stores the identification information ID2 (telephone number, mail address, etc.) of the mobile station 2 of the user B and the identification information ID3 (phone number, mail address, etc.) of the mobile station 3 of the user C stored in the storage unit 18. ) Is read out and displayed on the display unit 16. In this situation, when the user A presses a predetermined button of the operation unit 17 (performs a predetermined operation), the control unit 15 detects it and the identification information ID1 (telephone number, mail) of the own station is stored in the storage unit 18. (Address etc.) is further read, a service registration message including identification information ID1, ID2, ID3 is generated, and control is performed so that the second wireless transmitting / receiving unit 14 transmits this service registration message to the base station 3 by a wireless signal. I do.

When the user A selects the distance range L to be managed by operating the operation unit 17, the service registration message includes information on the selected distance range L1.

Here, the distance range L to be managed is a set distance with respect to how far another mobile station is away from the mobile station 1 which is the management mobile station, and the separation notification is made by the user A.
Is specified by, for example, selecting either wide (50 m) or narrow (10 m), or by directly selecting the distance.

By this control, the second radio transmitter / receiver 14
The service registration message is transmitted from the antenna 12 as a wireless signal.

The base station 3 receives this radio signal by the antenna and transmits a service registration message to the exchange 7 via the base station controller.

Upon receiving the service registration message, the switching device 7 controls the control unit 72 to provide information such as message contents “ID1”, “ID2”, “ID3”, and “L1” to the service management table of the database 73. Register (memorize) in.

The service registration table will be briefly described. An example of the service registration table is shown in FIG.

The service registration table includes management mobile station identification information (here, a plurality of mobile station 1 may be used if necessary) and managed mobile station identification information (here, mobile stations 2 and 3). It may be more than this), distance range, and management mobile station identification information and managed mobile station identification information.

In this embodiment, "ID
“1”, “ID2”, “ID3”, and “L1” are stored.

The managed mobile station and the managed mobile station can be specified from the message contents of the service registration message. For example, when only one management mobile station is recognized, the head of the service registration message is the management mobile station identification information ID 1 and the subsequent identification information IDs of other mobile stations.
2, the ID 3, etc. are determined by the control unit 72 as a managed mobile station and stored in the database 73. When a plurality of managed mobile stations are recognized, for example, the number of managed mobile stations is set to N at the beginning of the service registration message, and subsequently N pieces of management mobile station identification information are included to further include the managed mobile station identification information. Good. As a result, the control unit 72 determines that the first N pieces of the identification information are managed mobile stations and the others as managed mobile stations.

When the control unit 72 of the exchange 7 completes the registration in the service registration table, it sends a service notification message to the mobile stations 2 and 3 which are the managed mobile stations.

This service notification message includes the identification information ID1 of the managing mobile station, and preferably further includes the distance range L1.

The mobile stations 2 and 3 receive the service notification message from the switching apparatus 7 by receiving the radio signal from the base station (in this case, the base station 2 together).

That is, the radio signal received by the second antenna is received by the second radio transmitter / receiver 14 and the demodulated data is input to the controller 15.

The control unit 15 detects the service notification message from the demodulated data and stores the information such as ID1, L1 and the like in the storage unit 18.

Then, the control unit 15 of the mobile stations 2 and 3 thereafter.
Periodically controls the first wireless transmission / reception unit 13 to acquire the position (P2, P3) of its own station, controls the second wireless transmission / reception unit 14, and causes the switching device 7 to communicate via the base station. On the other hand, its own identification information and its own location information ((X2, Y2),
Send a location message containing (X3, Y3)).
Similarly, the mobile station 1 also transmits a position message including its own identification information and its own position information (X1, Y1) to the exchange 7.

The control unit 72 of the switching device 7 controls the mobile station 1,
The position information included in the position message received from each of 2 and 3 is stored in the position information area of the service registration table. Since the position message is periodically transmitted, the position information is sequentially updated.

Now, in addition to updating the position information, the control unit 72 of the exchange 7 uses the position information to obtain a predetermined distance from the management mobile station (when the distance range is stored in the database 73, the distance is stored). It is determined whether or not there is a managed mobile station that is more than the range L1) away. When there is a remote managed mobile station, a remote notification message including the identification information of the remote managed mobile station, which is a predetermined distance away, is transmitted to the mobile mobile station (mobile station 1 in this case).

The control unit 15 of the mobile station 1 which receives this,
The display unit 16 displays the identification information of the mobile station which has been separated and which has been notified.

Preferably, the exchange 7 stores the position symbol corresponding to the database 73 as shown in FIG. 6, and stores the position symbol corresponding to the position information of the managed mobile station separated from the managing mobile station. It is desirable to select and send the position symbol information by including it in the separation notification message. As a result, under the control of the control unit 15 of the management mobile station, a position symbol useful for identifying the whereabouts is displayed on the display unit 16 in accordance with the identification information of the mobile stations separated from each other. Make a call,
It is possible to give an instruction such as waiting in front of the displayed position symbol.

On the other hand, the control unit 72 of the switching device 7 also sends a separation notification message to the managed mobile stations that are separated.

The control unit 15 of the managed mobile station which receives this
Similarly, the display unit 16 displays a message indicating that it has fallen off.

The above is a description of the collective movement support service, but preferably, the switching device 7 periodically reads the position information of the managed mobile station from the database 73 and transmits it to the managed mobile station. desirable.

Further, regarding the calculation / distance detection when there are a plurality of managed mobile stations, a predetermined distance (if the distance range is stored in the database 73, the distance range L1 from any of the plurality of managed mobile stations). ) It is desirable to detect managed mobile stations that are more than one distance apart.

In addition, in order to calculate the distance in the above embodiment, two pieces of position information (latitude and longitude) for calculating the distance are used.
The distance may be obtained by converting the latitude difference and the longitude difference of 1 to meters and taking the square sum √.

In the embodiment, the switching device 7 is used as the service providing device, but the control unit 7 is provided in the mobile network.
