Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paging system, and more particularly to a paging system in which the location of a telephone can be displayed as map information on a display unit of a paging receiver.

[0002]

2. Description of the Related Art Conventionally, this type of system is for calling a person who has a paging receiver with display (hereinafter abbreviated as a receiver), and as shown in FIG.
It comprises an exchange 2, a subscriber telephone 3, and a receiver 5 carried by the holder 4. That is, when it is desired to contact the receiver holder 4, the subscriber telephone 3 dials the individual number of the receiver 5. The dialed individual number is sent to the base station 1 via the exchange 2, where it is converted into an ID signal corresponding to the dial, and is transmitted after modulating a radio wave. The receiver 5 receives this, and performs notification by a ringing tone or the like only when the ID signal coincides with its own ID signal, and simultaneously displays a message on the display unit. Thus, the owner 4 of the receiver 5 that has received the call can know the business from the contents of the message.

[0003]

In the above-mentioned conventional system, a simple message can be communicated to the owner of the receiver, or a caller can be instructed to contact.
However, if the following need arises when the owner of the receiver is in an unfamiliar land, there is a problem that the precious messages and instructions cannot be used effectively. That is, although the telephone number of the other party to be contacted is notified, it is not known how to go from the current location to the location. Also, when trying to get directions to the other party by telephone, it is difficult to hear because they do not know their current location. An object of the present invention is to provide a system in which the location of the user and the location of the other party are displayed on a display unit so that the receiver can be effectively used.

[0004]

According to the paging system of the present invention, the base station has a storage unit for storing the location of each subscriber telephone, and the receiver is configured to display a map on the display unit. , A signal of a predetermined format can be transmitted to the base station through the subscriber telephone set. When the format signal is transmitted, the base station transmits a signal including the location of the subscriber telephone set and transmits the signal to the receiver. It is configured to display a map indicating the location of the telephone.
Further, when a predetermined format signal addressed to another subscriber telephone is transmitted from one subscriber telephone, the base station calculates the route between one subscriber telephone and the other subscriber telephone, and calculates the route of each subscriber telephone. A signal including the location and its route is transmitted, and the paging receiver with display is configured to display a map showing the location and route of these subscriber telephones.

[0005]

According to the present invention, it is possible to display a map indicating the location and the route of the subscriber telephone set on the display unit of the receiver, and by viewing this map, the owner of the receiver can use the receiver effectively. It becomes possible to plan.

[0006]

Next, the present invention will be described with reference to the drawings. FIG. 1 is a block diagram of one embodiment of the present invention. In the figure, 1 is a base station, 2 is an exchange, 3 is a group of subscriber telephones, and 5 is a receiver (paging receiver with display) carried by the holder 4. The base station 1 includes a storage unit 11 that stores the locations of a plurality of mobile telephones constituting the group of subscriber telephone sets 3, here, four telephones A to D, a transmitter 12 that transmits an ID signal and a message, , And is connected to each of the subscriber telephones A to D via the exchange 2. The receiver 5 is configured to be able to display a map on the display unit.

The operation of the present invention in such a system configuration will be described. First, when the receiver holder 4 wants to know his / her location, he dials the individual number of his / her receiver using any one of the subscriber telephones. For example, dialing is performed using the telephone set D, and the telephone set D
Is connected to the base station, the base station 1 sends the subscriber telephone D
Is specified through the exchange 2 to put a message into the server. At this time, as shown in FIG. 4, the holder 4 switches the mode switch 51 of the receiver 5 as a message signal, sends out a predetermined signal from the speaker unit 52, and transmits this signal to the base station through the microphone of the subscriber telephone set D. To send to. This signal is stored in the storage unit 11 of the base station 1 as shown in FIG.
"Access signal" and "own ID" for accessing
Number ".

[0008] Then, the base station 1 which has received this signal reads out the location information of the subscriber telephone D to which the control unit 13 has been dialed from the storage unit 11, and receives the "synchronization signal" and "reception" as shown in FIG. The transmitter 12 sends a signal composed of the “ID signal of the device” and “map information of the location of the subscriber telephone set D” by radio waves. When this signal is received by the receiver 5, the location of the subscriber telephone set D is displayed on a display unit of the receiver 5 as a map as shown in FIG. As a result, the owner 4 of the receiver 5 can know the location of the subscriber telephone, that is, the current location.

On the other hand, when the owner 4 of the receiver 5 wants to know the route to the location of the subscriber telephone set in contact with, for example, the subscriber telephone set B, the subscriber 4 of his / her current location is referred to. The user dials the individual number of the target subscriber telephone set B by using the dial number. At this time, a signal from the speaker unit 52 of the receiver 5 is used as described above. Then, in the base station 1, the control unit 13 reads the location information of the subscriber telephone set B and the subscriber telephone set D from the storage unit 11, calculates the route from the subscriber telephone set D to B, and obtains the "synchronization" as shown in FIG. A signal composed of "signal", "receiver ID signal", and "calculated map information" is transmitted from the transmitter by radio waves. When this signal is received by the receiver 5, as shown in FIG. 6, the positions of the subscriber telephones B, D and the directions from the subscriber telephones D to B are displayed on a map on the display unit of the receiver 5. As a result, the holder 4 can easily go to the destination.

[0010]

As described above, according to the present invention, the base station receives a predetermined format signal from a subscriber telephone, transmits a signal including the location and route of the subscriber telephone and the other subscriber telephone, and transmits the signal to the receiver. Since this signal can be received and a map can be displayed on the display unit, the owner of the receiver can know his / her current position, destination position, and further directions to the destination position by looking at the map on the display unit. Thus, the receiver can be effectively used.
