Background art

Pager communication system for sending radio calls and short messages (eg, Poda

Kettle) is used. Pager receiver terminals do not have a transmission function, but are widely used because they are small and lightweight and are portable. It also has the feature of low power consumption due to a high intermittent reception ratio.

The pager communication system provides a wide area service, multi-area service, etc. in addition to a local area service of several hundred kilometers, and has the largest service area in mobile communications.

Since the pager communication system uses relatively low frequencies, for example, the 150 MHz band and the 280 MHz band, it has a feature that it is extremely resistant to blocking radio waves by obstacles.

Cellular communication systems include mobile phones such as car phones, cellular phones, and PHS, and are capable of advanced data communications. However, cellular communication systems use higher frequency bands than pager communication systems. The currently used PDC system uses the 800 MHz band or the 1.5 GHz band, and the PHS system uses the 1.9 GHz band. The next-generation mobile communication standard IMT-2000 will use the 2 GHz band.

Therefore, stations with complex structures, such as stations and underground shopping malls, have the disadvantage that they cannot be used because radio waves do not reach them. A large number of base stations may be provided so that they can be used in such places, but the installation of cellular base stations is expensive.

The outline of the mobile communication system of the present example will be described with reference to FIG. The mobile communication system of this example includes a central control station 10, a pager base station 21, a cellular base station 31, 32, 33, and a mobile station or mobile communication terminal 50 owned by a user. The central control station 10 is connected to a fixed telephone device or a fixed communication terminal 60 via a public network 40. As will be described later, the mobile station or mobile communication terminal 50 includes a pager receiving terminal unit 50 A having a pager receiving terminal function and a cellular communication terminal unit 50 B having a cellular communication terminal function. Includes both pager and cellular communication services.

In the location registration area 20 of the pager communication system, a plurality of pager base stations 21 (only one is shown in FIG. 1) are arranged. The pager communication system has the same numbering system as ordinary telephones, and one telephone number is assigned to each pager receiving terminal. I can

The location registration area of a cellular communication system includes a plurality of cells (three cells 30A, 30B, and 30C are shown in FIG. 1), and each cell has one cellular base station 31, 3 2 and 3 3 are installed.

The cellular communication system includes a PDC system, an NTT digital mobile communication system, a PHS system, and the like.

The central control station 10 is a control section 11 for controlling the entire central control station, a pager central station section 12, a cellular control station section 13, a storage section 14, and a message generation section for generating a predetermined message. 1 and 5.

The pager central office 12 has the function of the pager central office in the pager communication system and has subscriber data including telephone numbers and wireless addresses. The cellular control local unit 13 has a function of a mobile communication control station or a gateway mobile communication switching center (G-MSC), and has a home location register (HLR) for location registration. In the case of the PDC system, a not-shown mobile communication switching center (V-MSC) is provided.

The storage unit 14 has subscriber data including a comparison table of the telephone number of the pager receiving terminal unit 50A and the telephone number of the cellular communication terminal unit 50B built in each mobile communication terminal 50. . In addition, it has a location registration area for pager communication services, a location registration area for cellular communication services, and a comparison table of cells.

When the caller dials the telephone number of the pager receiving terminal unit 50 A on the called side, the caller is connected to the pager central unit 12 of the central control station 10 via the public telephone network 40 or the cellular communication system. Is done. The pager central office 12 extracts the wireless address associated with the telephone number of the called party from the subscriber data, and transmits a wireless address signal and a message signal to all the pager base stations 21. All the pager base stations 21 transmit the radio address signal and the message signal at the same radio frequency at the same time, that is, simultaneously. The pager receiving terminal unit 50A decodes and displays the message signal together with the sound when the received signal includes the wireless address signal of the own station.

When the caller dials the telephone number of the called cellular communication terminal unit 50B, the cellular system of the central control station 10 is switched via the public telephone network 40 or the cellular communication system. It is connected to local office 13. Cellular control unit 13 detects the location registration area of called side cellular communication terminal unit 50B from the home location register (HLR). Cellular base stations 31, 32, and 33 transmit a paging signal on the broadcast channel. Upon receiving the communication channel establishment request from the called-side cellular communication terminal unit 50B, the cellular base station selects a vacant communication channel and transmits it to the called-side cellular communication terminal unit 50B. The called cellular communication terminal unit 50B switches to the assigned communication channel. It goes into a call state after authentication and the like. With reference to FIG. 2, the function of the message generator 15 of the central control station 10 of the present example will be described. The call transmitted via the cellular control station 13 and the cellular base stations 31, 32, 33 was not connected to the cellular communication terminal 50 B of the called mobile communication terminal 50. In this case, a voice message is sent to the caller indicating that the cellular communication terminal 50B of the called mobile communication terminal 50 is out of reach of radio waves or the power is turned off. Is done.

In this example, a message indicating that a call has been received is transmitted in real time to the pager receiving terminal unit 50A on the called side via the pager wireless communication system.

In step S101, if the call is not connected to the called-side cellular communication terminal unit 50B, a connection disable signal is transmitted from the cellular control station unit 13 to the control unit 11 . The control unit 11 sends a message generation instruction to the message generation unit 15. In step S102, the message generator 15 obtains the telephone number of the calling party. Next, in step S103, it is determined whether there is a message from the calling party. If there is a message from the calling party, it is transmitted to the called party via the Bayer communication system in step S105. The case where the message is transmitted from the caller will be described later with reference to FIG.

If there is no message from the calling party, a message is generated in step S104 and transmitted to the called party via the pager communication system in step S105.

The message should include at least the caller's phone number, date and time. Thus, in this example, when a call cannot be connected to the cellular communication terminal 50B of the mobile communication terminal 50, a message including the telephone number and date and time of the caller is sent to the pager of the callee. Receiving Sent to the communication terminal unit 50A. The message is displayed as text or audio on the screen of the display unit. Thus, the callee can receive the message in real time.

An example of the mobile communication terminal 50 of the present example will be described with reference to FIG. The mobile communication terminal 50 of this example has a pager receiving terminal unit 50A, a cellular communication terminal unit 50B, and a control unit 50C. The mobile communication terminal of this example further includes a display unit, an input key, a receiver, a transmitter, a beep sound generator, and the like, which are not shown.

The pager receiving terminal unit 50A has a function of receiving a radio call and a short message, and has no transmitting function. The direct conversion method or the super heterodyne method may be used. The cellular communication terminal section 50B may have any configuration as long as it has the function of a cellular type mobile communication terminal, such as the currently used PDC method, PHS method, or next-generation mobile communication terminal. It may have the same configuration as that of the IMT-20000 mobile communication terminal.

The control unit 50C controls the power supply of the pager receiving terminal unit 50A for controlling the power on / off of the pager receiving terminal unit 50A, and controls the power on / off of the cellular communication terminal unit 50B. A power control unit 52 for the cellular communication terminal unit, a radio field intensity level determination unit 53 for determining whether the received radio field intensity of the cellular communication terminal unit 50B is smaller than a predetermined level, Main CPU 54 for controlling the overall operation, ROM 55 storing control programs, various constants, information entered by the user, etc., RAM 56 used as an operation area, various types Operation to control flash memory or electrically erasable writable ROM (EE PROM) 57 that stores data and tables, data input from input keys and data output to the display unit, etc. CPU 58 and these components Between the elements and has a signal bus 59 for connecting these components and the pager receiving terminal unit 5 O A and cellular communication terminal unit 5 0 B.

The function of the radio wave intensity level determination unit 53 will be described later with reference to FIG. The main CPU 54 performs various controls such as control of a transmission / reception sequence operation in the pager reception terminal unit 50A and the cellular communication terminal unit 50B, modulation and decoding of a transmission / reception control signal, and control of a transmission / reception protocol. Operation unit CPU 58 is a pager receiving terminal unit 50 The message received by A and the data received by cellular communication terminal unit 50B are displayed on the display unit. For example, by operating the input key, the user data stored in the EEPROM 57 is displayed on the display unit.

The ROM 55 or the EPROM 57 stores a location registration area for the pager communication service, a location registration area for the cellular communication service, and a comparison table of cells.

Note that the mobile communication terminal 50 of the present example may be configured to be able to operate in the power saving mode. In the power saving mode, only the power of the bayer receiving terminal unit 50A is turned on and the power of the cellular communication terminal unit 50B is turned off by the operation of the power control units 51 and 52. For details of the power saving mode, refer to Japanese Patent Application No. 2000-32244 filed on Oct. 23, 2000 by the same applicant as the present applicant. The contents of Japanese Patent Application No. 2000-32244 are incorporated herein by reference.

Next, the operation of position registration and area registration in the mobile communication system of this example will be described with reference to the state change diagram of FIG. In a cellular communication system, the area in which a cellular communication terminal is located is registered in advance so that automatic reception is possible in any cell or area. This location registration is normally performed at the home location register (HLR) of the central control station 10. Similarly, in the pager communication system, the area where the pager receiving terminal is located is registered in advance.

In state S201, the power of the mobile communication terminal 50 of this example is turned on. In the state S2, the location registration of the cellular communication terminal unit 50B is executed, and then in the state S203, the area of the pager receiving terminal unit 5OA is registered. In this example, the area registration of the pager receiving terminal 5OA is automatically performed when the location of the cellular communication terminal 50B is registered.

The location registration of the cellular communication terminal unit 50B may be executed when the power is turned on or at a predetermined period. Alternatively, it may be performed for each call, as in the PDC method. The location registration of the cellular communication terminal 50B is performed by the cellular communication terminal 50B itself, but the area registration of the pager receiving terminal 50A has its own transmission function. Therefore, it cannot be executed by the pager receiving terminal unit 50A itself. As described above, the storage unit 14 of the central control station 10 stores the telephone line number of the cellular communication terminal unit 50 B of each mobile communication terminal 50 and the subscriber data of the pager reception terminal unit 50 A. It stores the overnight comparison table, the location registration area of the pager communication service, the location registration area of the cellular communication service, and the cell comparison table. When the location registration of the cellular communication terminal unit 50B is performed, the control unit 11 associates the telephone number of the cellular communication terminal unit 50B with which the location registration is to be performed with reference to the comparison table of the storage unit 14. The pager receives the telephone number of the receiving terminal unit 50A and registers the area in the pager communication system.

Thus, in this example, when the location registration of the cellular communication terminal 50B is performed, the area registration of the pager receiving terminal 5OA built in the mobile communication terminal is automatically performed.

In the above example, the location registration and the area registration were performed simultaneously using the comparison table stored in the storage unit 14 of the central control station 10. However, the ROM of the control unit 50 of the mobile communication terminal was used. A reference table stored in 55 or EEPROM 57 may be used. When the location registration of the cellular communication terminal unit 50B is performed, the area of the pager communication service is detected with reference to the comparison table stored in 0 ^^ 5 or £ 1 ^] \ 57. The position information of the cellular communication terminal unit 50B and the area information of the pager receiving terminal unit 50A are transmitted to the central control station 10 via the cellular communication terminal unit 50B. The central control station 10 performs location registration in the cellular communication service and area registration in the pager reception service based on the location information and the area information transmitted from the mobile communication terminal 50.

When the position registration of the cellular communication terminal unit 50B and the area registration of the pager reception terminal unit 50A are completed, the mobile communication terminal enters a reception waiting state in state S204. When the mobile communication terminal moves and changes the location registration area of the cellular communication system in the reception waiting state, the mobile station returns to state S202 again and performs location registration. As described above, when location registration is performed, area registration is also performed.

If there is an incoming call in the reception waiting state, a call is executed in state S206, and when the call ends, the state returns to the state S204 reception waiting state. In addition, move during communication When the location registration area or cell is changed by the above, it is necessary to switch the channel during communication in the state S207.

The operation of the radio field intensity level determination unit 53 of the control unit 50C of the mobile communication terminal of this example will be described with reference to FIG. First, in step S301, it is determined whether the user has turned on the power of the cellular communication terminal unit 50B. If the user has turned on the power of the cellular communication terminal 50 B, in step S 302, the radio wave intensity level determination section 53 determines whether the received radio wave of the cellular communication terminal section 50 B has been received. It is determined whether the intensity is smaller than a predetermined level.

If the received radio wave intensity is lower than the predetermined level, the power of the pager receiving terminal unit 50A is turned on in step S303. Accordingly, in step S304, only bayer receiving terminal section 50A is in a state of waiting for reception.

Even if the user turns off the power of the cellular communication terminal unit 50B in step S301, the power of the pager receiving terminal unit 50A is turned on in step S303, and the step S303 is executed. At step 304, only the pager receiving terminal section 50A is in a waiting state for reception. At step S302, if the received radio wave intensity is greater than or equal to the predetermined level, then at step S305, Then, the cellular communication terminal 50B enters a state of waiting for reception. In this case, the power of the pager receiving terminal unit 50A may be turned off to reduce the power consumption.

When the pager receiving terminal unit 50A in step S304 is waiting for reception, even if there is an incoming call, the cellular communication terminal unit 50B is not connected. However, in such a case, the predetermined message is transmitted to the pager receiving terminal unit 50A as described above, so that the user can know that there is an incoming call in real time.

A configuration example of the telephone device 60 of the present example will be described with reference to FIG. The telephone device 60 of the present example has a control unit 61 for controlling the entire device, a telephone number of the pager receiving terminal unit 50 A built in all mobile communication terminals, and a cellular communication terminal unit. 50 A storage unit that stores a comparison table of B phone numbers 62, a message registration unit 63 that stores a plurality of fixed message phrases, and a message creation unit that allows users to create their own messages 6 4 and the message is transmitted via the pager And a transmitting unit 65 for transmitting to the pager receiving terminal unit 5 OA of the communication terminal. The telephone device of the present embodiment may be any of a fixed telephone such as a public telephone, a subscriber telephone, or a cellular telephone. Of course, the mobile communication terminal of FIG. 1 may be used.

The operation of the telephone device of the present embodiment will be described with reference to FIGS. If a call is made to the cellular communication terminal unit 50B of the mobile communication terminal 50 via the telephone device 60 and the call is not connected, as shown in FIG. The message “Cannot connect” appears on the screen and the message “Send message” appears.

When "Send" is selected, a question as to how to create the message is displayed as shown in Fig. 8, and "Use boilerplate" and "Create it yourself" appear.

When "Use fixed phrases" is selected, a list of the fixed phrases registered in the message registration section 63 is displayed. The user can select a desired message from this list and send it. If you select "Create your own", you can generate and send any message from the input device. Of course, you can also add your own generated messages to the fixed phrases.

The message contains the caller's name, phone number, date and time, and so on. The message is transmitted to the pager receiving terminal unit 5OA of the called mobile communication terminal via the pager communication system.
