2. Description of the Related Art In recent years, with the increase in needs for mobile communication and the development of communication technology, the installation and expansion of cellular mobile communication systems have been rapidly progressing. When using a cellular mobile communication system, a user purchases a terminal device of a desired system and also applies for use of a service to an operator of the system. As a result, the user can receive a communication service such as a mobile call or mobile data communication using his / her own terminal device anywhere in the service area of the system.

[0003] This type of mobile communication system includes, in addition to a public communication network, for example, a private communication network laid in a department store, a business office, or a hotel, and the latter independently provides various services. The user of the terminal device can use a service provided by the private communication network by dialing a special number, for example.

Incidentally, in order to use the above service, it is necessary to notify the user of the terminal device by some means that the user has entered the service area of the private communication network. Therefore, in recent years, when the location registration of a terminal device within the service area of a private communication network has been successful, the network sends a message to the terminal device, and the user of the terminal device enters the service area. A system has been proposed to inform the user of the fact.

However, depending on the above system, even when the terminal device enters the service area, the location registration with the network may not be performed. For example, the service area of the private communication network forms a part of the service area of the public communication network, and the service area of the private communication network and the cell of the public communication network adjacent to this service area are included in the same call area. This is the case. In such a case, even if the terminal device moves from the cell of the public communication network to the service area of the private communication network, no message is sent from the private communication network to this terminal device because the calling area is the same. . For this reason, the user cannot know that he / she has entered the service area of the private communication network, and cannot receive the service of the private communication network.

Accordingly, the present invention provides a mobile communication system in which a user of a terminal device can be informed that a user of a terminal device has entered a service area of a private communication network regardless of presence / absence of location registration, thereby further improving serviceability.

The transmission timing of the control signal by the control signal transmission means is at least one of a regular, irregular, or a time when a message stored in the message storage means is updated.

With this configuration, in the service area of the private communication network, for example, the message stored in the message storage means is updated periodically, irregularly, or for the terminal device having the common terminal identification information. Message information is broadcast at the point in time. Therefore, when a terminal device having the common terminal identification information enters the service area, the message information is received by the terminal device and reported to the owner, regardless of the presence or absence of the location registration. Therefore, the user of the terminal device can surely recognize that he / she has entered the service area where the private communication network is deployed.

In another aspect of the present invention, in the above object,
In the wireless control device, among the plurality of terminal devices, common terminal identification information storage means for storing common terminal identification information given separately from individual identification information for a specific plurality of terminal devices, Control for storing control message information for controlling at least one of a dial tone and a ringing tone of a terminal device in association with the common terminal identification information stored in the common terminal identification information storage means. Message storage means, and control signal sending means for sending a control signal including the control message information and the common terminal identification information to the specific terminal devices existing in the service area via the base station. And, in the terminal device, a storage unit for storing the common terminal identification information given to the own device in advance, and the control signal sending unit Control signal receiving means for receiving the transmitted control signal, and when the control signal corresponding to the common terminal identification information stored in the own device is received by the control signal receiving means, the control signal It is characterized by comprising a changing means for variably setting at least one of the generation form of the dial tone or the ringing tone based on the included control message information.

[0011] According to this structure, in the service area of the private communication network, the control message information for prompting the terminal device having the common terminal identification information to variably set the generation mode of at least one of the dial tone and the ringing tone is broadcast. Is done. Therefore, when the terminal device having the common terminal identification information enters the service area, at least one of the outgoing sound and the incoming ringing sound changes in the terminal device regardless of the presence or absence of the location registration. Therefore, the user of the terminal device can surely recognize that he / she has entered the service area where the private communication network is deployed.

However, it is assumed that “20:00” is stored as the transmission end time and “60 seconds” is stored as the transmission interval. Further, it is assumed that the transmission time corresponding to the message 2 is “20:00”.

In this state, when the time reaches "10:00" (step S6a), the radio control unit EX sends a non-ringing incoming signal to each of the terminal devices located in the service area S2 of the private communication network. And the base stations CS21 to CS2m
(Step S6b). This non-ringing incoming signal is an incoming signal in which no ringing sound is generated by setting with the terminal device, and the common terminal identification number “9000” and the message information “A department bargain information: dial 123” And ".

Next, the radio control unit EX determines whether or not the time to end the message transmission has been reached based on the contents stored in the transmission time storage table 53 in FIG. 4 (step S).
6c). Here, if the determination is Yes, the wireless control device EX ends the transmission of the non-ringing incoming signal. No
Is determined, the wireless control device EX determines in step S
After moving to 6d, the next message transmission time is set, and then the process returns to step S6a to wait for the next message transmission time.

In this way, a non-ringing incoming signal is transmitted at predetermined time intervals to each of the terminal devices located in the service area S2 of the private communication network in a predetermined time zone. become.

Next, a processing procedure in the terminal device PS4 located in the service area S2 of the private communication network will be described with reference to the flowchart of FIG. Note that other terminal devices P
The service area S of the private communication network for S1 to PS3
In the case where the user is in the area 2, the same processing is performed.

First, the user of the terminal device PS4 inputs the common terminal identification number "9000" in advance and stores it in the common terminal identification number storage section 111. In this state, it is assumed that PS4 has entered service area S2 of the private communication network.

Then, the terminal device PS4 stores the common terminal identification number “9” stored in the common terminal identification number storage unit 111.
The terminal device PS4 receives the non-ringing incoming signal corresponding to 000 "(step S7a). Then, the terminal device PS4 extracts the message information included in the received non-ringing incoming signal, and for example, as shown in FIG. (Step S7b) Then, the terminal device PS4 determines whether or not the non-ringing incoming signal corresponding to the above “9000” has been received again within a predetermined time (Step S7c).

Here, if the determination is Yes, the terminal device PS4 continues to display the message. On the other hand, for example, the terminal device PS4 goes out of the service area S2 of the private communication network or the wireless control device EX has finished sending out the no-ringing incoming signal. When the determination is made, the terminal device PS4
Shifts to step S7d to delete the message on the LCD 13.

Thus, in the present embodiment, for each of the terminal devices located within the service area S2 of the private communication network, the non-ringing incoming signal including the common terminal identification number and the corresponding message information is transmitted for a predetermined time. Sent at intervals.
The terminal device located in the service area S2 of the private communication network receives the non-ringing incoming signal including the common terminal identification number corresponding to the common terminal identification number stored in the terminal device. The terminal device that has received the non-ringing incoming signal extracts the message information included in the non-ringing incoming signal and displays it on the LCD 13. When the non-ringing incoming signal is not received for a predetermined time or more, the terminal device deletes the display message on the LCD 13.

For this reason, the user of the terminal device is
By looking at the above displayed message, it is possible to clearly recognize that the user has entered the service area where the wireless control device EX is deployed. Further, since the non-ringing incoming signal is transmitted regardless of the presence / absence of the location registration, the message can be notified even when the location registration request is not made from the terminal device. Further, if the non-ringing incoming signal is not received for a predetermined time or more, the display message on the LCD 13 is deleted.
The user of the terminal device can clearly recognize that he has left the service area where the wireless control device EX is deployed.

(Second Embodiment) The mobile communication system according to the present embodiment generates a dial tone by using a non-ringing incoming signal from a wireless control device to a terminal device entering a service area of a private communication network. Is transmitted, and upon receiving the control message, the terminal device changes its own tone generation mode in response to the control message. Note that the basic configuration according to the second embodiment is almost the same as that described in the first embodiment, and a detailed description thereof will be omitted.

The radio control unit EX inserts the control message for variably setting the common terminal identification number and the tone generation mode toward the terminal having the common terminal identification number which has entered the service area of the radio control apparatus EX. The non-ringing incoming signal is periodically transmitted.

On the other hand, as shown in FIG. 10, the terminal device has a generation mode storage unit 1101 in addition to the common terminal identification number storage unit 111 in the storage unit 110. The generation form storage unit 1101 stores a ringing period of a dial tone in association with each of the common terminal identification numbers stored in the own device.

As shown in FIG. 9, the control unit 100 of the terminal device has, as its control function, a non-ringing incoming signal reception control unit 101 in addition to various normal control units relating to wireless access and wireless communication. And a change control unit 1001. When the generation mode change control unit 1001 receives the non-ringing incoming signal, the generation mode storage unit 1101
The ringing period of the dial tone of the own device is changed based on the ringing period of the dial tone stored in the device.

Next, the operation of the mobile communication system of the present embodiment configured as described above will be described according to the control procedure of the terminal device. FIG. 11 is a flowchart illustrating a control procedure of the terminal device PS4 located in the service area S2 of the private communication network. Note that the other terminal devices PS1 to PS3
Is performed in the case where the terminal is located in the service area S2 of the private communication network.

First, the terminal device PS4 receives the common terminal identification number “90” stored in the common terminal identification number storage unit 111.
The terminal device PS4 receives the non-ringing incoming signal corresponding to “00” (step S11a), and sets the ringing period of the dial tone to the common terminal identification number “9000” based on the storage content of the generation form storage unit 1101. (Step S11b) For example, the continuous sound for the public network is switched to a sound having a predetermined intermittent cycle.

Next, the terminal device PS4 determines whether or not the non-ringing incoming signal corresponding to the above “9000” has been received again within a predetermined time (step S11c). Here, Yes
Is determined, the terminal device PS4 keeps the state in which the ringing period of the dial tone is switched. On the other hand, for example, the terminal device PS4 goes out of the service area S2 of the private communication network or the wireless control device EX has finished sending out the no-ringing incoming signal, so that re-reception was not performed (NO).
Is determined, the terminal device PS4 proceeds to step S1.
The process proceeds to 1d to restore the ringing period of the dial tone.

Thus, in this embodiment, for each of the terminal devices located in the service area S2 of the private communication network, the non-ringing incoming signal including the common terminal identification number and the control message corresponding thereto is transmitted for a predetermined time. Sent at intervals.
The terminal device located in the service area S2 of the private communication network receives the non-ringing incoming signal including the common terminal identification number corresponding to the common terminal identification number stored in the terminal device. The terminal device that has received the non-ringing incoming signal switches to a terminal based on the common terminal identification number that stores the ringing period of the dial tone. If the non-ringing incoming signal has not been received for a predetermined time or more, the terminal device restores the ringing period of the dial tone.

Therefore, the user of the terminal device can clearly recognize that the user has entered the service area where the wireless control device EX is deployed due to the change of the ringing period of the dial tone. Further, since the non-ringing incoming signal is transmitted regardless of the presence / absence of the location registration, the message can be notified even when the location registration request is not made from the terminal device. Further, if the non-ringing incoming signal is not received for a predetermined time or more, the ringing cycle of the dial tone returns to its original state, so that the user of the terminal device can clearly recognize that he / she has left the service area deployed by the wireless control device EX. Become.

The present invention is not limited to the above embodiments. For example, in the first embodiment, the non-ringing incoming signal is repeatedly transmitted within a certain time period. However, depending on the message information, there is a case where only one transmission is required (for example, message 2 of “9000”, “bargain finished”). FIG. 12 shows the processing procedure at this time. That is,
A predetermined message sending time (in this case, “2
0:00 "), the wireless control device EX transmits the non-ringing incoming signal only once.

Further, when the message information is updated, a non-ringing incoming signal including the updated new message information may be transmitted. FIG. 13 shows a processing procedure at this time. By doing so, it becomes possible to notify the user of new message information more quickly.

Further, in the first embodiment, the case where the common terminal identification number "9000" is a number for general users and message information is reported to general users using this number has been described. Alternatively, specific message information may be notified only to a specific user by setting a common terminal identification number for the specific user. By doing so, it becomes possible to notify the message information only to a specific related person.
For example, the common terminal identification number “9001” is stored only in the terminal device owned by the employee of the department store A, and is not stored in the terminal device owned by a general user. Further, in the wireless control device EX, information on the stock of the product is stored in association with the common terminal identification number “9001”. By doing so, it is possible to inform only the employees of the department store A of the information on the stock.

In each of the above embodiments, the terminal device extracts and displays the message information included in the non-ringing incoming signal, but this is not necessarily required.
For example, when the terminal device receives the non-ringing incoming signal, the terminal device user may be notified of the fact (for example, by switching display symbols on the LCD 13). Alternatively, information that prompts the user of the terminal device to register the location may be displayed. Even in this case, the user can be notified that the user has entered the service area S2 of the private communication network, so that the object of the present invention is achieved. Further, in this case, it is not necessary to include the message information as shown in FIG. 3 in the non-ringing incoming signal, so that the configuration can be simplified.

In the second embodiment, the ringing period of the ringing tone is changed. However, the ringing period of the ringing tone may be changed. Further, not only the ringing period of the dial tone or the ringing tone of the incoming call may be changed, but also the tone and the pitch thereof may be changed. Even in this case, the service area S2 of the private communication network is provided to the user.
It is possible to notify that the user has entered the inside, and the object of the present invention is achieved. In addition, various modifications can be made without departing from the spirit of the present invention.
