Abstract

PURPOSE:To expand a service area optionally without reconstructing a fixed network only by installing a base station device optionally and independently by determining whether the communication of a mobile equipment is allowed or not and its charging processing by using a credit communication function provided originally to the fixed network. CONSTITUTION:Only when a registered subscriber number and a password number which are sent from the mobile equipment 4 match one of combinations of subscriber numbers and password numbers stored in a device 10, the communication from the mobile equipment 4 is connected to an opposite party requested by the mobile equipment 4. Then the charge for communication is integrated by the device 10 corresponding to the registered subscriber numbers. Thus, the credit communication function of the fixed network is utilized, so the service area can be expanded optionally without reconstructing the fixed network side nor installing a communication line between base stations only by connecting base station devices 2, 3, 6-8 to the subscriber line 6 of the fixed network.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention is for realizing a mobile communication section using a simple connection control method and device in a public mobile communication system that connects to a fixed communication network.

(Conventional Technique #) The first and simplest mobile communication system connected to a fixed network is a cordless telephone.

In this system, a radio device called a connecting device is connected to the subscriber side end of a subscriber line of a fixed network, and communicates with a portable radio device called a slave device. It has an extremely simple configuration in that it can be used without any modifications to the fixed network. However, since fixed-line call charges are charged to the subscriber of the subscriber telephone, it is not possible to allow an unspecified number of people to use the handset. That is, cordless telephones have the disadvantage that they cannot be used as a public mobile communication system.

In order to use them as public mobile communications, as shown in Figure 5, each handset is assigned a unique number, the control device records the call charges corresponding to these numbers, and the subscriber of each handset is assigned a unique number. There is a first method of charging. Figure 5 is a diagram for explaining the conventional technology, in which 1 is a fixed network subscriber exchange (hereinafter referred to as L).
2 is a control device, 3 is a base station side radio, 4 is a mobile device, 5 is a connection line to other exchanges in the fixed network, 6 is a subscriber line, and 7 is a radio and control device. The connection line 8.9 is an antenna. Subscripts 4 and 9 represent that the mobile devices are different for each subscriber. When making a call from a mobile device, when the subscriber operates the mobile device 4 to make a call, the mobile device number i (i = 1 to N in the example shown)
However, antenna 9. Antenna 8. Radio 3. The information is transmitted to the control device 2 via the connection line 7, and the control device 2 uses the number i to confirm that the calling portable device is a subscriber of its own system, and sets up a communication path with the portable device. If you are not a subscriber to your own system, you will not be allowed to connect because you will not be able to bill for the fee.

The dialed numbers from the connected mobile devices reach the control device 2 in the above order and further reach the subscriber II! 6 and then sent to the LS. From then on, connections will be made in the same way as normal. After the call ends, the call fee is recorded in the connecting device 2 corresponding to the subscriber number i, and billed offline to the subscriber.

A method of notifying the control device 2 of call charges from the fixed network by using a public telephone interface with the fixed network;
The control device 2 can know the fixed network call charges by providing the control device 2 with a function to calculate the fixed network call charges by itself like a hotel PBX. In this case as well, modification of the fixed network is not required, but the base station side radio equipment is
Because it is a stand, the service area is limited. Although it is possible to expand the service area by increasing the transmission power, there is a limit in terms of the size and power consumption of the portable device. Furthermore, in order to expand the service area, it is conceivable to install a plurality of base station wireless devices 3 separated by an appropriate distance. However, in this case, a separate device (hereinafter referred to as a subscriber file device) is required to manage which mobile devices have subscribed to the system, and each time an individual mobile device makes a call, Since each base station control device needs to access this subscriber file device online, it is necessary to provide a control line directly between all base station devices and the subscriber file device, and the configuration of the mobile communication section is It had the disadvantage of being complicated.

The second method is to configure a large-scale network in the mobile communication area, such as with car phones, but this naturally has the disadvantage that the configuration of the mobile communication area is more complicated than the first method. be.

(Problems to be Solved by the Invention) The present invention is a public mobile communication system that does not require changes to the fixed network, does not require communication lines between multiple base stations, and can configure a service area of any size. The purpose is to realize a connection control method.

(Means for Solving the Problems) The features of the present invention include a device that stores and manages registered subscription numbers and passwords registered in advance, an exchange that accesses this device when a specific dial number is received, and A registered subscription number that consists of a base station device connected to an exchange and a mobile device that can connect to the base station device wirelessly, and in which the registered subscription number and password sent from the mobile device are stored in the device. Connection control in mobile communications in which communication from the mobile device is connected to the party requested by the mobile device only when the password and password match one of the combinations, and communication charges are accumulated by the device according to the registered subscription number. It's in the method.

(Function) According to the present invention, whether or not to permit communication of a mobile device and its billing process are performed using a credit call function conventionally provided in fixed networks.

(Example) FIG. 1 is a diagram illustrating a first example of the present invention,
10 is a new service exchange; 11 is an interoffice transmission line; 12 is a subscriber line exchange on the receiving side; 13 is a subscriber line on the receiving side;
4 is the telephone of the called party. 2,3°6.7.8 with a subscript indicates that a plurality of these devices are installed at different locations.

Next, this operation will be explained. Each mobile communication subscriber also subscribes to the so-called credit calling service of the fixed network at the same time. A credit call service is a service where you register in advance the charges for calls made from any phone and have them charged to your own phone number.In order to confirm your identity, when making a credit call, you must enter your own phone number ( Dial the registered telephone number (hereinafter referred to as a registered telephone number), a personal identification number (hereinafter referred to as a credit number) that has been determined in advance and registered on the fixed-line network side but is kept secret from others, and the number of the other party with whom you wish to connect. These dial numbers are the new service exchange IO
transmitted to. The new service exchange 10 includes a list of customers subscribing to the credit calling service (registered telephone numbers,
and credit card numbers), and only if the registered telephone number and credit card number in this list match the registered telephone number and credit card number in the dial, the subscriber is considered to be an authorized subscriber and the connection is made.

In this way, a mobile communication subscriber also subscribes to a credit calling service using, for example, his or her home telephone number as a registered telephone number. When making a call from a mobile device, the mobile subscriber dials like a normal credit card call. That is, first, the user raises the hook of the portable device and performs a calling operation. The portable device thereby sends a call request signal to the base station. 4,9.8
, 3.7, this signal is transmitted to the control device 2. The control device 2 sends a call permission signal in response to this, thereby forming a wireless communication path between the portable device and the base station. After this, there is a service identification number (
Below this is r121. ). The subscriber dialed r121. enters the subscriber line exchange 1 via the control devices 2 to 6. 1 is the dial number r121. It identifies that the call is a credit call and connects it to the new service exchange 10 via 5. The new service exchange 10 sends the second dial signal to the mobile device side. When the mobile subscriber hears the second dialing signal, he dials the registered telephone number, the credit card number, and the destination telephone number in this order. This dial signal reaches the new service exchange 10 through the same route as the previous dial number r121°, and the IO checks whether there is a match among the registered telephone number and credit number combinations in memory. , if they match, the connection is made via the interoffice transmission line 11 to the subscriber line exchange 12 on the receiving side. 12 is further connected via 13 to the called subscriber's telephone 14 to enable a telephone conversation. If the registered telephone number and credit card number do not match, the new service exchange 10 assumes that the subscriber is not an authorized subscriber and does not make any further connection. If you are connected, you are a regular credit card subscriber, and the call fee will be charged to the subscriber with the registered phone number. Furthermore, in a system in which the usage fee for the wireless section is collected from the subscriber, the control device 2 may record the frequency of use of the wireless section for each registered telephone number, and bill the subscriber for each registered telephone number at once. .

In order to expand the service area, it is sufficient to simply install the base station devices 2, 3, 6, 7.8 at different locations as shown in FIG. No matter which base station your mobile device uses to make a call, you can connect without any problems. Moreover, the base station device only needs to be connected to a fixed network subscriber line, and there is no need for communication lines between base stations. In other words, any location where a subscriber line can be installed can be used as a service area. In the case of a system in which a fee is charged for the use of a wireless section in the case of a plurality of base stations, the frequency of use of each registered telephone number recorded in each base station may be totaled and billed to the subscriber.

In this way, by using the credit calling function of the fixed network, you can do it without making any modifications to the fixed network.
Moreover, by simply connecting a base station device to a subscriber line of a fixed network, the service area can be expanded arbitrarily without installing communication lines between base stations. Furthermore, since charges are applied to your own number no matter which mobile device calls you, there is the advantage that all mobile devices can be used in common by anyone. Even if a person who owns a portable device wants to let someone else use it, if that person subscribes to a credit card calling service, the person will be charged for it, so they can lend it with confidence.

FIG. 2 shows the control device 2, base station radio 3, and
1 and 2 show an example of the configuration of the portable device 4. 15 is a control signal transmission/reception circuit, 16 is a recording circuit that records the frequency of use of the wireless section for each registered telephone number, 17 is a control circuit that controls 15 and 16, 18 is a wireless transmitter, 19 is a wireless receiver, and 20 is a 21 is a transmitting/receiving device, 22 is a wireless transmitter, 23 is a wireless receiver, 24 is a control circuit, and 25 is a telephone set.

Next, FIG. 3 shows an example of the configuration of the control device 2 of the base station device according to the second embodiment of the present invention. 26 is a switch, and 27 is a control line for controlling 26. The registered telephone number and credit card number are stored in the mobile device. Since the control circuit 24 of the portable device is usually composed of a microprocessor or the like, storage of these numbers can be easily realized by writing them into a memory connected to the processor. When making a call from a portable device, when the mobile subscriber hooks off to make a call, the control circuit 24 sends a call request signal to the base station. This signal is demodulated by the base station radio 3 and sent via 7 to the control device 2 . The switch 26 of the control device 2 is normally turned off, and the signal from the portable device is received by the control signal transmitting/receiving circuit 15 and decoded by the control signal transmitting/receiving circuit 17 . The control circuit 17 that has received the call request signal sends a call permission signal to the portable device via 15, thereby establishing a communication path between the portable device and the base station. The portable device that receives the call permission signal sends the registered telephone number and credit card number stored in the control circuit 24 to the base station. The base station temporarily stores this signal in the control circuit 17. Thereafter, the telephone number of the other party dialed by the mobile subscriber is also sent to the base station and similarly stored once in the control circuit 17. After receiving and storing all of the registered phone number, credit card number, and destination phone number from the mobile device in this way, the control circuit 17 turns on the switch 17 via 27, and then changes to r1 via 6.
21. Sends a dial signal. As a result, switch 1
connects lines up to 10, and 10 sends a second dial signal to the portable device. When the base station control device 2 detects this at 15, it sends the registered telephone number, credit number, and destination telephone number stored in 17 via 15. The following operations are the same as in the first embodiment.

As a result, the mobile subscriber does not need to dial as many numbers as in the case of credit card calls, and can connect by simply dialing the telephone number of the other party, improving operability. Further, in the case of the first embodiment, since it is necessary to dial the credit card number, only those who know the credit card number can use it. This means that if you allow someone who does not subscribe to a credit card call service to use your mobile device, you will need to tell them your credit card number, and there is a risk that your credit card call will be used illegally later. This is also convenient since there is no need to dial a credit card number.

The credit card call described above is what is called automatic credit, and as the name suggests, the registered telephone number and credit card number are automatically verified. However, in addition to automatic credit, there is also what is called manual credit. This connects the credit toll call to the switchboard operator, and the subscriber verbally tells the operator the registration number and credit number.

The switchboard operator will match these numbers to the new service switch, and if a match is made, the connection will be made. That is, with automatic credit, it is necessary to add a routing function to the new service exchange to the fixed network, whereas with automatic credit, this is not necessary. Therefore, manual credit makes it easy to expand the service area, but automatic credit can only be used in areas where this function is added to the fixed network. For this reason, it is common to start automatic credit services in some areas, gradually expand the service area, and then provide manual credit services nationwide.

The third embodiment is applied to such a case where automatic credit and manual credit coexist. In the second embodiment, the base station connected to the exchange serving automatic credit is the same as described above, but from the base station connected to the exchange in the manual credit service area, The mobile device is notified via the control line that it is in the manual credit call area. When the mobile device receives this notification, it stops the automatic sending function of the registered telephone number and credit card number. When making a call from a mobile device, the mobile subscriber orally notifies the operator of the registered telephone number and credit card number instead of automatic transmission. The following connection procedure is exactly the same as for manual credit.

When a mobile device displays whether the subscriber is in an automatic credit area or a manual credit area using the above-mentioned signal from the base station, the subscriber can take appropriate action.

In the fourth embodiment, the subscriber can make a call using the same dialing operation, whether automatically or manually.

The configuration and operation of the base station device in the automatic credit call service area are the same as those in the second embodiment, but the control device of the base station in the manual credit call service area has the configuration shown in FIG. . 28 is a synthesized speech generator. The configuration and operation of the mobile device are similar to those in Embodiment 2, and when the subscriber goes off-hook, it automatically sends out a call request signal, and when it receives a call permission signal from the base station, it sends out the stored registered telephone number and The credit card number is sent to the base station, and then the subscriber's dialed telephone number is sent. At the base station in the manual credit call service area, the registered telephone number, credit number, and destination telephone number from the mobile device are temporarily stored in 17, as in the case of the second embodiment. After that, turn on the switch 26, and dial a signal (hereinafter 10) representing a manual credit call.
6) is sent to 1. As a result, 1 connects to the manual credit switchboard and notifies the switchboard of the incoming call. While the operator is calling, a ringback tone is sent toward the base station, and when the operator answers, the ringback tone is cut off. The base station 15 detects the presence or absence of this ringback tone, and if the tone is cut off, it assumes that the operator has responded, and the base station 17 activates the 28 to transmit, for example, the next synthesized voice to the operator. "Please make a credit card call. The registered phone number is X, the credit card number is Y, and the other party's phone number is 2." Here, X, Y, and Z are received from the mobile device and stored temporarily. These are the registered phone number, credit card number, and the other party's phone number. As a result, the operator connects using the same operation as a normal manual credit card. Although the timing for transmitting the synthesized voice has been explained by cutting off the ringback tone, it is also possible to transmit the synthesized voice repeatedly at the same time as the switch 26 is turned on. When the switchboard operator responds, the entire announcement can be heard during the second round of the above announcements.

In the above explanation, we connected a call path from the LS to the new service exchange, and then connected from there to the called side. The present invention is also applicable to a system in which the new service exchange notifies the LS only of the result of whether or not the credit number has been verified, and if the verification is successful, the LS is connected to the called party.

Further, in the above example, the credit calling function of the fixed communication network is used, but this function may be provided separately from the existing fixed network. That is, up until now, the station that manages credit numbers, etc. has been referred to as the new service exchange, but in this case, it can be read as the mobile communication control device. The mobile communication control device is connected to a fixed network. New service exchange (
121 (or 106) is used as the number for accessing the mobile communication controller (or the operator of the switchboard handling credit calls), but the number for accessing the mobile communication control device may be replaced with, for example, a subscriber number of a fixed network. Furthermore, in this case, the number corresponding to the registered telephone number when using fixed network credit calling may be a subscription number to the mobile communication system that is independent of the fixed network telephone number.

In the fifth embodiment, the mobile communication control device calculates call charges for wireless sections and fixed networks. This eliminates the need for any billing control in the base station device, resulting in an extremely simple configuration.

(Effects of the Invention) As explained above, since the credit number for fixed-line credit calls or the PIN stored in a separately provided mobile communication control device is used as collateral for billing call charges,
There is no need for the base station to check whether the subscriber is a valid subscriber each time a connection is made, and therefore there is no need to make any modifications to the fixed network, and base station equipment can be installed arbitrarily and independently. The service area can be expanded arbitrarily. Since each base station device can be installed independently, there is no need for communication lines between the base station devices, and the system can be configured extremely easily.
