Abstract

Base stations (BSs (BS1, BS2, BS3)), pager base station (13k), and groups (G1, G2, G3, G4, G5) of portable communication terminals are provided in one pager communication system area (Ak). Each portable communication terminal has a cellular radio communication machine and a pager receiver. Each group includes portable communication terminals (1) and uses the same telephone circuit. The cellular radio communication machines of the portable communication terminals use the same pager communication circuit. The portable communication terminals (1) have IDs different from one another. When one of the portable communication terminals (1) in one group starts communication, the information on the location of the portable communication terminal is registered in a VLR. Even if a second portable communication terminal (1) in the same group starts communication, the registration of the location of the second portable communication is rejected.

Description

Description Wireless communication control station device and wireless communication device

The present invention relates to a wireless communication control station device and a wireless communication device. Background art

In a mobile communication system such as a PDC (Personal Digital Cellular), there are two types: a VLR (Visitor Location Register) that registers the location of mobile communication terminals, and an HLR (Home location Register) that registers user billing information and the like. It has two data paces and manages these databases for each mobile communication terminal. This user information management cost occurs regardless of the frequency of use, and is reflected in the so-called basic fee. This is uneconomic for infrequent users.

On the other hand, a pager communication system that can send short messages (wireless paging system, pager) is the most widely used system in mobile communication. The service area of a pager communication system generally starts with a regional service on a prefecture-by-prefecture basis, and provides a wide range of services such as wide area services and multi-area services. A servicer of a pager communication system usually has one pager central station and a plurality of pager base stations. When the caller dials the calling number of the pager receiver (wireless paging receiver), the caller is connected to a pager device in the pager central office, and the pager device receives an address signal for identifying the corresponding pager receiver and an input message signal. To each pager base station. The signal sent to each pager base station is converted to a radio signal and transmitted simultaneously from each station at the same radio frequency. If the pager receiver receives its own address signal in the received selective call signal, it sounds a sound, decodes the message signal, and displays the content.

In addition, intermittent reception is performed to reduce the power consumption of the receiver. In the pager communication system, a high intermittent reception ratio is realized, and the power consumption is extremely low. However, with the rapid spread of cellular communication systems, the number of pager communication system users has dropped sharply in recent years, and the infrastructure has not been used effectively.

In the pager communication system, the pager receiver does not have a transmission mechanism, so the user needs to perform location registration. When the user moves from one area to another, he calls the registered representative number using his telephone and enters his / her calling number and the number of the area to be moved. Thereby, the area information of the transfer destination is stored in the central office.

Here, the basic signaling function of a mobile phone (portable communication terminal) in a cellular communication system will be described with reference to the operation state transition diagram of FIG.

When the power of the mobile communication terminal is turned on in step 151, first, position registration 152 is performed. Here, the mobile communication terminal is registered on the network side so that a call can be made from the network side to receive a call regardless of the location of the mobile communication terminal. When the location (area) information broadcast via the broadcast channel changes, the mobile communication terminal performs location registration.

After the location registration 15 2, the mobile communication terminal shifts to the standby state 15 3. In the cellular communication system, by setting a paging channel (PCH: paging channel), the mobile communication terminal performs intermittent reception in this standby state 153 in synchronization with the paging channel to which each belongs. Since the power of the radio unit is turned off during the period when the paging channel is not received, power consumption can be reduced.

When a start button or the like is operated to make a call, the state shifts to the calling state 154. Here, a call signal is transmitted to the base station, the communication channel is allocated, the communication state is shifted to 156, and communication is performed. When an incoming call signal is received via the paging channel, the terminal enters the incoming call state 155, responds to the call, shifts to the specified call channel, and enters the communication state 156. In addition, when the user moves across cells during a call, channel switching 157 is performed. When the call is terminated, disconnection 158 is performed, and the mobile phone returns to the standby state 153.

In recent years, the number of users of mobile terminals such as PDCs and cellular mobile communication terminals has increased rapidly. One family may have multiple mobile communication terminals. Eg house Each member of the tribe may have their own mobile communication terminal. Even in such a case, a contract must be made with a telecommunications carrier for each mobile communication terminal, and a basic fee must be paid every month. Some members of the family use mobile communication devices frequently, while others use power infrequently. Therefore, it is economically problematic to pay the basic fee for all mobile communication terminals.

As shown in FIG. 1, a wireless communication device (portable communication terminal) 1 of the present invention includes a receiver for a pager communication system (pager receiver) 2, a wireless device for a cellular communication system (cellular wireless device) 3, and The wireless communication device 1 includes a control unit 4 that controls the entirety of the wireless communication device 1 and controls turning on / off of power to the pager receiver 2 and the cellular wireless device 3. The cellular radio 3 is configured to be turned on in response to a signal transmitted via the pager communication system.

FIG. 2 shows a schematic configuration of the entire wireless communication system including the wireless communication control station device of the present invention. FIG. In FIG. 2, reference numeral 1 denotes a wireless communication device (portable communication terminal) of the present invention that incorporates the pager receiver 2 and the cellular wireless device 3 described above.

MSCk, MS Ck + l, and MS Ck + 2 are control stations. These control stations include a pager central station 11 k, 1 lk + l, 1 having a central station function of a pager communication system (paging). Cell communication system control stations 12k, .12k + 1, and 12k + 2 each having the function of a control station in the lk + 2 and the cellular communication system are provided. Control stations MSCk, MS Ck + l, and MS Ck + 2 correspond to pager communication system areas Ak, Ak + 1, and Ak + 2, respectively.Control stations MS Ck, MS Ck + 1, and MS Ck + 2 Connected to the public network.

Pager central stations 1 lk, 1 lk + l, 1 lk + 2 are connected to pager base stations 13 k, 13 k + l, 13 k + 2, respectively, and these pager base stations 13 k, 13 k + l, 13 k +2 corresponds to the pager communication system areas Ak, Ak + 1, and Ak + 2, respectively. A plurality of cellular base stations BS are provided in each pager communication system area Ak, Ak + 1, Ak + 2, and each of the cellular communication system control stations 12k, 12k + l, and 12k + 2 is a pager communication system area. It is connected to multiple cellular base stations BS in Ak, Ak + 1 and Ak + 2.

The control stations MS Ck, MS Ck + 1, and MS Ck + 2 have a VLR (Visitor Location Register) that registers the location of the mobile communication terminal 1 and an HLR (Home location Register) that registers user billing information. Have been. VLR and HLR are interconnected and share information.

Figure 3 shows multiple cellular base stations BS (BS1, BS2, BS3), pager base station 13k and multiple mobile communication terminal groups Gl, G2, G3, G4, in a single pager communication system area Ak. Indicates G5. According to the present example, a plurality of mobile communication terminals 1 are thus grouped. One telephone line and one pager communication line are allocated to one group. Therefore, the cellular radios 3 of the plurality of mobile communication terminals 1 included in each group use the same telephone line. Multiple _c control station MS C k pager receiver 2 use the same pager number of the mobile communication terminal 1 included in each group, charged with any one of the mobile communication terminal 1 power in one group Then, the location information of the mobile communication terminal is registered in the VLR. Also the same glue When the other mobile communication terminal 1 in the group attempts to start communication, the location registration is rejected, and the display unit of the mobile communication terminal displays that fact. 'An example of a database registered in the HLR is shown with reference to Figs. FIG. 4 shows a first example of mobile communication terminal information registered in the HLR. In this example, all the mobile communication terminals 1 in the group have the same cellular telephone number and pager number, and different IDs are assigned to the respective mobile communication terminals 1. FIG. 5 shows a second example of the information of the mobile communication terminal 1 registered in the HLR. In this example, the cellular telephone numbers of all the mobile communication terminals 1 in the group are different from each other, but the pager numbers are the same, and the mobile communication terminals 1 have different IDs. FIG. 6 shows a third example of the information of the mobile communication terminal 1 registered in the HLR. In this example, the cellular telephone numbers of all the mobile communication terminals 1 in the group are the same, but the bayer numbers are different from each other, and the mobile communication terminals 1 are given different IDs. FIG. 6 shows a fourth example of the information of the mobile communication terminal 1 registered in the HLR. In this example, the cellular telephone numbers and pager numbers of all the mobile communication terminals 1 in the group are different from each other, and different IDs are assigned to the respective mobile communication terminals 1.

With reference to FIG. 8, the connection of the mobile communication terminal of the present example will be described for the first example of FIG. 4 and the third example of FIG. When a call is made from the mobile communication terminal on the calling side to the cellular radio 3 of the mobile communication terminal 1 of the present example shown in FIG. 4 or FIG. 6, the control stations MS Ck, MS Ck + 1, and MS Ck + 2 Inquires the HLR if the cellular telephone number of the called party is registered as grouped mobile communication terminal information as shown in FIG. 4 or FIG. If the called party's cellular telephone number is not grouped and registered in the HLR, it is determined that the called party's mobile communication terminal is a normal cellular mobile communication terminal and processed.

If the called party's cellular telephone number is registered as a group in the HLR, the control stations MS Ck, MS Ck + l, and MS Ck + 2 send the called party's mobile phone to the calling party. Request the ID of communication terminal 1. In the example of Fig. 4 or Fig. 6, since the cellular telephone numbers in the group are all the same, the control stations MS Ck, MS Ck + l, and MS Ck + 2 request connection to one cellular radio 3 Can not do it. Therefore, it requests the calling party for the ID of the called party, and thereby requests the mobile communication terminal 1 to connect. The control stations MS Ck, MS Ck + 1, and MS Ck + 2 are connected in advance to the pager receiver 2 of the portable communication terminal 1 of the called party via the pager communication system. In the example of FIG. 4, since all pager numbers in the group are the same, connection is made to pager receiver 2 of the called party based on the ID received from the calling party. The connected mobile communication terminal 1 turns on the power of the cellular radio 3. In the example of Fig. 6, since the pager numbers in the group are different, the control stations MSCk, MSCk + l, and MSCk + 2 identify the pager number based on the ID received from the caller, and The mobile communication terminal 1 is connected to the pager receiver 2 of the communication terminal 1, and the mobile communication terminal 1 turns on the power of the cellular radio 3. After that, in both cases of Figs. 4 and 6, the control stations MSC k, MS C k + l and MS C k + 2 use one mobile communication based on the ID of the called party received from the calling party. Connect to cellular radio 3 of terminal 1.

With reference to FIG. 9, the connection of the mobile communication terminal of the present example will be described for the second example of FIG. 5 and the fourth example of FIG. When a call is made from the calling side mobile communication terminal to the cellular radio 3 of the mobile communication terminal 1 of the present example shown in FIG. 5 or FIG. 7, the control stations MS Ck, MS C k + l, MS C k + Step 2 queries the HLR whether the called party's cellular discourse number is registered as grouped mobile communication terminal information as shown in FIG. 5 or FIG. If the called party's cellular telephone number is not grouped and registered in the HLR, it is determined that the called party's mobile communication terminal is a normal cellular mobile communication terminal and processed.

In the example of Fig. 5, when the cellular telephone numbers of the called party are registered in the HLR as a group, the cellular telephone numbers in the group are all different, so the control stations MS C k, MS Ck + l, and MS C k + 2 generates an ID based on the cellular phone number. In the example of Fig. 7, since the cellular telephone numbers and the pager numbers in the group are all different, the control stations MS C k, MS C k + l, and MS C k + 2 need not use the ID, but use the mobile communication terminal. One can be individually identified.

The control stations MS Ck, MSCk + l, and MS Ck + 2 connect in advance to the pager receiver 2 of the portable communication terminal 1 of the called party via the pager communication system. In the example of FIG. 5, since all pager numbers in the group are the same, connection is made to the called party's Bayer receiver 2 based on the ID corresponding to the cellular telephone number. This connected mobile communication The terminal 1 turns on the power of the cellular radio 3. In the example of Fig. 7, since the cellular telephone numbers and pager numbers in the group are all different, the control stations MSCk, MSCk + 1, and MSCk + 2 specify the pager number based on the cellular telephone number, The mobile communication terminal 1 is connected to the pager receiver 2 of the specified mobile communication terminal 1, and the mobile communication terminal 1 turns on the cellular radio 3. Thereafter, in both of the examples of FIGS. 5 and 7, the control stations MSC k, MSC k + l, and MS C k + 2 connect to the cellular radio 3 of one portable communication terminal 1 based on the cellular telephone number. .

The connection of the cellular radio 3 of the called party's radio communication device (portable communication terminal) 1 will be described below. In this example, by using the cellular communication system and the pager communication system together, it is possible to effectively use the pager communication system in which the number of users has been drastically reduced.

As shown in FIG. 10, when the operation of the wireless communication device 1 of the present invention is started, first, after the power of the cellular wireless device 3 is turned on (61), it is determined whether the position registration of the cellular communication system is possible. It is determined whether or not it is (62). If another wireless communication device 1 in the same group has already established communication, new location registration is impossible, and in that case, a message indicating that location registration is impossible is displayed on the display unit 56 of the wireless communication device 1. Display (71) and end communication (72).

If location registration is possible, location registration is performed (63), and it is determined whether there is a call to the cellular radio via the pager communication system (64). Immediately after power-on, the result of this determination is NO.

Next, it is determined whether the current position is within the service area of the pager communication system (65). This determination is made by referring to the correspondence table between the area of the pager communication system and the cells of the cellular communication system stored in the ROM or the EEPROM.

If the result of this determination is that it is not within the service area of the pager communication system, a message indicating that location registration is not possible is displayed and displayed on the display unit 56 (80), and the power is turned off (81).

After the end of the communication (72), the process returns to the determination (65) of whether or not the communication is within the service area of the pager communication system. On the other hand, if the current position is within the service area of the pager communication system, area registration is performed for the pager communication system (66). This area registration is performed via the cellular radio system 3 via the cellular communication system. That is, the control unit 4 supplies an area registration signal for the pager central station 11 k to the cellular radio 3 and transmits the signal via the cellular radio 3. The area registration signal received by the cellular base station and sent to the cellular communication system control station 12 k is notified from the cellular communication system control station 12 k to the pager central station 11 k. In this way, the area registration of the pager communication system is automatically performed via the cellular communication system.

In the above description, the area registration is performed by transmitting an area registration signal from the mobile communication terminal 1 to the central station of the pager communication system, but the control station MSCk stores the stored pager communication. The control station MSCk may automatically register the area using a correspondence table indicating the correspondence between the system area and the cell of the cellular communication system. That is, when the location registration (63) of the cellular communication system is performed, the location registration (63) is referred to by referring to the correspondence table between the area and the cell and the correspondence table of the telephone number, pager number and ID. 3) The pager number may be automatically registered in the area corresponding to the specified cell.

Next, the power of the pager receiver is turned on (66), and the power of the cellular radio is turned off (68). Then, the pager communication system enters a standby state (69). In the standby state (69), when a call is made via the pager communication system, the type of the call (the type of message) is determined (70). If the call is a normal paging service call, A normal paging service is received (79), and after the reception is completed (78), the state shifts to the standby state (69) of the pager communication system. On the other hand, if it is a call to the cellular radio (a call request to the cellular radio, a message instructing to turn on the cellular radio 3), the cellular radio 3 is turned on (6). 1) If location registration is possible, perform location registration (63). If the call is a call to a cellular radio (64), the process proceeds to standby (73) of the cellular communication system, receives a paging channel, receives a paging signal for itself (75), and makes a call. Against After transmitting the response signal, communication is performed on the designated communication channel (76). Then, channel switching (77) is performed as necessary, and after the communication is completed (72), the process returns to the determination (65) as to whether or not it is within the service area of the paging communication system. In FIG. 10, if the mobile communication terminal is not within the service area in (65), the communication is terminated (81) after the message (80). However, as shown in FIG. 11, the similar message (80) It is also possible to wait intermittently while receiving the position information signal from the pager base station (13k etc.) later (81B). When the position information data is received, the process returns to (66), and the same processing as in FIG. 10 is performed. As shown in FIG. 12, when there is an incoming call to the cellular radio (91), the control station MS Ck determines whether or not this cellular radio is registered in the group (FIGS. 4 to 7). Is determined (92). As described above, the wireless communication device 1 of the present invention is configured to automatically register an area in a service area of a major communication system via a cellular communication system when the wireless communication device 1 is located in the service area. Have been. Therefore, the control station MS Ck refers to the correspondence table between the pager number and the telephone number, finds out the pager number corresponding to the telephone number of the incoming call, and receives the pager at the pager central office 11k. Determines whether the machine is registered in the pager communication system. On the other hand, when the pager receiver having the number corresponding to the called telephone number is not registered in the group, the process is performed in the same manner as the incoming call in the ordinary cellular communication system (93).

If the phone number has been registered as a group, it is determined whether or not location registration of the telephone number in the VLR is possible (94). As described with reference to FIG. 3, if another mobile communication terminal in the same group has already been registered, location registration is impossible. If location registration is not possible, a message indicating that location registration is not possible is displayed on the caller's communication device (95). When location registration is possible, in the examples of Figs. 4 and 6, there are multiple mobile communication terminals for the same telephone number, and it is necessary to identify them by ID. Prompt for input (96). In response to this, an ID is input, and when the control station MSCk receives the ID (97), an incoming call signal for the cellular radio is converted to a signal for the pager communication system (with the address signal of the corresponding receiver). Message to turn on cellular radio 3 (98), and call is made via the pager communication system. In other words, the pager central office 11k transmits, to a pager receiver corresponding to the called cellular radio, information indicating that there is an incoming call to the cellular radio (or (A message instructing the cellular radio 3 to be powered on) is transmitted via the paging base station 13 (99). As a result, the cellular radio 3 in the mobile communication terminal 1 is turned on, and the cellular radio 3 performs initial cell search and location registration, and starts receiving a paging channel (100) . In the examples of FIGS. 5 and 7, since the telephone numbers of the mobile communication terminals are different from each other, the ID can be generated from the database. Therefore, the steps (96) and (97) are unnecessary.

Next, the cellular communication system control station section 12 k calls the cellular radio device via the paging channel of the cellular communication system (10 l) _c. Thereby, the cellular radio device 3 It will be possible to receive paging channels, receive incoming call signals to the local station, and perform communication.

Thereafter, the end of the communication is monitored (102), and it is determined whether the position registration should be deleted at the end of the communication (103). Once the location registration of the mobile communication terminal whose location has been registered is kept as it is, other mobile communication terminals in the same group will not be able to register the location after that, so if you try to increase the use frequency of all the mobile communication terminals in the group, communication It is preferable to delete the location registration immediately after completion. However, if location registration is maintained, there is an advantage that connection processing is performed quickly when using the same mobile communication terminal in cascade. In addition, the location registration is kept, and when a call or an incoming call is made to another mobile communication terminal, it is notified to the registered mobile communication terminal via the pager communication system, and the power is turned off. It is also possible to make it available.

Here, whether or not to delete the location registration is set by the user or the communication service company, and if it is to be deleted, the process of deleting the location registration is performed (104).

Note that one priority mobile communication terminal (hereinafter referred to as a priority terminal) is defined for each mobile communication terminal in one group, and that mobile communication terminal retains its location registration unless the power is turned off. Good. For example, in one family, if the mother's mobile communication terminal is the priority terminal, the mother can control the use of the mobile communication terminal of another family. mother Parents only need to turn off the priority device when other family members allow the use of the device.

Further, when the location registration of such a priority mobile phone is performed, the outgoing call or incoming call of another mobile communication terminal is notified to the priority terminal via the pager communication system, and the priority terminal is permitted (priority terminal). Power off).

The operation of the control station shown in FIG. 12 described above simply turned on the power of the cellular radio 3 when calling the cellular radio 3 via the pager communication system. Next, an embodiment will be described in which paging information required for the cellular radio device 3 is transmitted via the pager communication system in addition to the above message.

FIG. 13 is a flowchart showing a flow of the operation of the control unit according to another embodiment.

As shown in FIG. 13, when the control station MS Ck arrives at the cellular radio 3 (1 1 1), it determines whether or not the cellular radio 3 is registered as a group (1). 12) If it is not registered, it is processed in the same way as for an incoming call in a normal cellular communication system (1 13).

If the phone number has been registered as a group, it is determined whether or not the phone number can be registered in the VLR (114). As in Fig. 12, if another mobile communication terminal in the same group has already been registered, location registration is not possible. If the location cannot be registered, a message indicating that the location cannot be registered is displayed on the caller's communication device (115). When location registration is possible, in the examples of Figs. 4 and 6, there are multiple mobile communication terminals for the same telephone number, and it is necessary to identify them by ID. A message prompting for input is displayed (1 1 6). In response to this, when the ID is input and the control station MSCk receives it (1 17), it calls the cellular radio 3 via the pager communication system (118, 1 19). As a result, the cellular radio 3 in the portable communication terminal 1 is turned on, the cellular radio 3 performs an initial cell search and location registration, and starts receiving a paging channel (120). In the examples of FIGS. 5 and 7, since the telephone numbers of the mobile communication terminals are different from each other, the ID can be generated from the database. Therefore, the steps (1 16) and (1 17) are unnecessary.

Up to this point, the configuration is the same as that of the embodiment shown in FIG. 12, but in this embodiment, a message instructing to turn on the cellular radio 3 is transmitted to After calling (1 1 9), the paging information necessary for the cellular radio 3 is transmitted as a message of the pager communication system (1 2 1). This paging information is sent from the pager receiver 2 to the control unit 4. Therefore, it is not necessary for the cellular radio 3 to receive the paging channel. Further, by referring to the correspondence table between the area of the pager communication system and the cell of the cellular communication system, the initial cell search in the cellular radio 3 can be performed. The range can be narrowed, and high-speed cell search can be performed.

After transmitting necessary paging information to the cellular radio 3 via the cellular communication system in the above described 121, the cellular communication system control station 12 k waits for a response signal from the cellular radio 3 After receiving (1 2 2), the communication channel is shifted to the communication channel and the communication of the cellular communication system is performed.

Thereafter, the end of the communication is monitored (123), and it is determined whether or not the position registration should be deleted at the end of the communication (122). Once the location registration of the mobile communication terminal whose location has been registered is kept as it is, other mobile communication terminals in the same group will not be able to register the location after that, so if you try to increase the use frequency of all the mobile communication terminals in the group, communication It is preferable to delete the location registration immediately after completion. However, if location registration is maintained, there is an advantage that connection processing is performed quickly when the same mobile communication terminal is used continuously.

In addition, the location registration is maintained, and when a call or an incoming call is made to another mobile communication terminal, it is notified to the registered mobile communication terminal via the pager communication system to request the power off. It is also possible to obtain.
