Description

  The present invention relates to a mobile radio communication method capable of reducing the number of communication networks used based on a plurality of mobile terminals owned by a user, and a mobile radio communication apparatus used therefor.

  As disclosed in Patent Document 1, it is known that one user possesses a plurality of portable terminals. Hereinafter, the term “user” means one user.

  FIG. 11 shows a mobile radio communication method and a mobile radio communication device used in the case where the user possesses the first mobile phone 1 and the second mobile phone 2 as a plurality of mobile terminals. In FIG. 11, the first and second mobile phones 1; 2 use different telecommunications carriers. Accordingly, a communication carrier that can use the first mobile phone 1 is referred to as a first communication carrier, and a communication carrier that can use the second mobile phone 2 is referred to as a second communication carrier. The first telecommunications carrier communication network 15 owned by the first telecommunications carrier and the second telecommunications carrier communication network 16 owned by the second telecommunications carrier are connected to each other by the gateway exchange 20 so that they can communicate with each other.

  In addition, the communication terminal of the communication partner is a communication terminal from which the user starts communication. Examples of communication terminals of communication partners include a first communication carrier compatible mobile phone 21 and a second communication carrier compatible mobile phone 22. The first communication carrier compatible mobile phone 21 is a mobile phone that can be used in the first communication carrier communication network 15. The second communication carrier compatible mobile phone 22 is a mobile phone that can be used in the second communication carrier communication network 16.

  When the user operates the first mobile phone 1 to start communication with the first mobile phone 21 that supports the first communication carrier, the first mobile phone 1 wirelessly passes through the first communication carrier communication network 15. The first communication carrier-compatible mobile phone 21 is communicably connected. On the other hand, when the user operates the first mobile phone 1 to start communication with the second mobile operator compatible mobile phone 22, the first mobile phone 1 is wirelessly connected to the first communication carrier communication network 15. Via the gateway exchange 20 and the second communication carrier communication network 16, it is connected to the mobile phone 22 corresponding to the second communication carrier so as to be communicable.

  In addition, when the user operates the second mobile phone 2 to start communication with the second mobile operator compatible mobile phone 22, the second mobile phone 2 wirelessly passes through the second communication carrier communication network 16. The second communication carrier compatible mobile phone 22 is communicably connected. On the other hand, when the user operates the second mobile phone 2 to start communication with the first mobile operator compatible mobile phone 21, the second mobile phone 2 is wirelessly connected from the second communication carrier communication network 16. Via the gateway exchange 20 and the first communication carrier communication network 15, it is connected to the first communication carrier compatible mobile phone 21 so as to be communicable.

  That is, in FIG. 11, since the first mobile phone 1 and the second mobile phone 2 are a plurality of mobile terminals with different communication operators, for example, the user operates the first mobile phone 1 to operate the second communication business. When trying to start communication with the mobile phone 22 corresponding to a person, the first mobile phone 1 makes a call to the first communication carrier communication network 15, and the first communication carrier communication network 15 is called by the second communication business. Since it is the operator network 16, it is connected to the second communication carrier communication network 16 via the gateway exchange 20. The second communication carrier communication network 16 recognizes that it is the second communication carrier-compatible mobile phone 22 that is the call destination, and calls the second communication carrier-compatible mobile phone 22. When the user of the mobile phone 22 for the second communication carrier responds to this call, the first mobile phone 1 and the mobile phone 22 for the second communication carrier can communicate. As described above, when the first mobile phone 1 communicates with the second communication carrier-compatible mobile phone 22, it passes through the two communication networks of the first communication carrier communication network 15 and the second communication carrier communication network 16. Become. For this reason, a communication fee is charged for each of the two communication networks, and there is a disadvantage that the communication cost is increased for the user.

  In addition, if the user knows the telecommunications carrier that can use the mobile phone of the communication partner, it is possible to use a plurality of mobile phones that are owned accordingly. However, there are generally a large number of communication partners of users such as several tens or more. For this reason, it is impossible for the user to appropriately store the telecommunications carriers that can use the mobile phones of many communication partners.

The transmission / reception antenna of the second Bluetooth transmission / reception unit 13 exists separately from the transmission / reception antenna of the second portable transmission / reception unit 12.

  The first and second mobile phones 1 and 2 are different from each other in usable communication carriers. A communication carrier that can use the first mobile phone 1 is a first communication carrier. A telecommunications carrier that can use the second mobile phone 2 is a second telecommunications carrier. The first and second carriers are different from each other. A telecommunications carrier having a different management from the first and second telecommunications carriers is assumed to be another telecommunications carrier. There are one or more different carriers.

  Hereinafter, the communication network owned by the first communication carrier is referred to as the first communication carrier communication network 15. A communication network owned by the second communication carrier is referred to as a second communication carrier communication network 16. A communication network owned by another communication carrier is referred to as another communication carrier communication network 17. When there are a plurality of different communication carriers, the separate communication carrier communication network 17 constitutes a separate communication network for each different communication carrier.

  The first communication carrier communication network 15 and the second communication carrier communication network 16 are connected to each other by a gateway exchange (not shown) so as to communicate with each other. The first communication carrier communication network 15 and the separate communication carrier communication network 17 are connected to each other by a gateway exchange 18 so that they can communicate with each other. The second communication carrier communication network 16 and the separate communication carrier communication network 17 are connected to each other by a gateway exchange 19 so that they can communicate with each other.

  The first communication carrier compatible mobile phone 21 is a mobile phone that can be used in the first communication carrier communication network 15. The second communication carrier compatible mobile phone 22 is a mobile phone that can be used in the second communication carrier communication network 16. The mobile phone 23 for another communication carrier is a mobile phone that can be used in the separate communication carrier communication network 17.

  A mobile radio communication method using a mobile radio communication device will be described with reference to FIG. In the sleep state in which the power switch (not shown) in the first and second mobile phones 1; 2 is turned on by the user and the first and second mobile control units 3; 11 are electrically activated, the user starts communication. When the telephone number of the communication partner to be communicated is input by operating the keyboard of the first mobile phone 1 as described above, the processing according to the flowchart displayed at the lower right of FIG.

  According to the processing of the above flowchart, first, after the calling process accompanying the input of the telephone number of the communication partner is started in step 101, the communication carrier determination unit 9 adds the communication carrier specifying information described later in steps 102 and 103. Based on this, it is determined whether or not the communication carrier that can use the communication terminal of the communication partner is the same as the communication carrier that can use the mobile terminal other than the first mobile phone 1 possessed by the user, that is, the second mobile phone 2. And the determination result is output to the first portable control unit 3.

  That is, in step 102, it is determined whether or not it is the first communication carrier, and in step 103, it is determined whether or not it is the second communication carrier, and the process proceeds to step 104 or step 105 as the determination result.

  For example, when the user starts communication using the first mobile phone 1 with the first mobile phone 21 corresponding to the first communication carrier as the communication partner, the communication carrier determination unit 9 determines in step 102 that the communication carriers are the same. In step 104, the first mobile control unit 3 of the first mobile phone 1 controls the first mobile transmission / reception unit 4 so that the first mobile phone 1 is connected to the first communication carrier communication network. Call 15. The first communication carrier communication network 15 that has received this call connects a wireless communication line to the mobile phone 21 corresponding to the first communication carrier of the communication partner.

  In addition, when the user starts communication using the first mobile phone 1 with the mobile phone 23 compatible with another communication carrier as the communication partner, the communication carrier determination unit 9 determines in step 102 and step 103 that the communication carriers are different. In step 104, the first portable control unit 3 of the first portable telephone 1 controls the first portable transmission / reception unit 4 so that the first portable telephone 1 performs the first communication. A call is made to the carrier communication network 15. Upon receiving this call, the first communication carrier communication network 15 connects the wireless line to the other communication carrier compatible mobile phone 23 via the gateway exchange 18 and the separate communication carrier communication network 17.

  When the user starts communication using the first mobile phone 1 with the second mobile operator compatible mobile phone 22 as the communication partner, in step 103, the communication operator determination unit 9 determines that the communication carriers are the same. In step 105, the first portable control unit 3 of the first mobile phone 1 controls the first Bluetooth transmission / reception unit 5 so that the first Bluetooth transmission / reception unit 5 becomes the second Bluetooth transmission / reception unit 13. Are connected so as to be communicable via a wireless line based on a wireless communication standard called Bluetooth. The second Bluetooth transmission / reception unit 13 notifies the second portable control unit 11 of the connection between the first and second Bluetooth transmission / reception units 5; 13, the second portable control unit 11 controls the second portable transmission / reception unit 12, and 2 The portable transmitting / receiving unit 12 uses the second communication carrier communication network 16 to connect a wireless line to the mobile phone 22 for the second communication carrier.

As described above, according to the mobile radio communication method of FIG. 1, when the first mobile phone 1 among a plurality of mobile terminals with different telecommunications carriers owned by the user is operated to start communication, , the same whether the first mobile phone 1 and the available network operators available operators of the second cellular phone 2 of the communication terminal of the communication partner is determined. When available operators of communication terminals of communication partners is not identical to the available carrier's second mobile phone 2, the first mobile phone 1 via the second mobile phone 2 Connect to the communication terminal of the communication partner without communication. Conversely, if the available carrier's terminal of communication partner is identical to the available carrier's second mobile phone 2, the first mobile phone 1 to the second mobile phone 2 Connect to the communication terminal of the communication partner via the communication. Therefore, the number of use of the communication network can be reduced based on the first and second mobile phones 1; 2 possessed by the user, and there is an advantage that the communication cost for the user is reduced.

  In FIG. 1, even when the second mobile phone 2 is operated so as to start communication, it can be used as in the case where the first mobile phone 1 is operated so as to start communication. In that case, a telecommunications carrier determination unit corresponding to the telecommunications carrier determination unit 9 and a telephone book corresponding to the telephone directory 10 are provided in a flash memory (not shown) of the second mobile phone 2. When the first mobile phone 1 is operated to start communication, the first mobile phone 1 in the description is read as the second mobile phone 2, and the second mobile phone 2 is read as the first mobile phone 1. Thus, the mobile radio communication method when the second mobile phone 2 is operated to start communication is used like the mobile radio communication method when the first mobile phone 1 is operated to start communication. You will understand what you can do.

  Referring to FIG. 2, a telecommunications carrier that can use a mobile terminal other than the first mobile phone 1 possessed by the user is a telecommunications carrier that can use the communication terminal of the communication partner based on the telecommunications carrier identification information. The internal configuration of the flash memory 7 that uses the domain of the mail address to determine whether or not they are the same will be described.

  The flash memory 7 is provided with a second portable communication carrier column 25 as a part for recording the communication carrier specifying information. The communication carrier identification information is information for specifying a second communication carrier that can be used by the second mobile phone 2 (see FIG. 1). For example, “vyz.ne.jp” is recorded in the second mobile communication operator column 25 as the domain of the mail address of the second mobile phone 2. In order to record the domain of the mail address in the second mobile communication operator column 25, for example, the user operates the keyboard of the first mobile phone 1 to set the domain of the mail address in the second mobile communication operator column 25. Let me record.

  In the name column of the telephone directory 10, the names of Mr. A, Mr. B, and Mr. C are recorded by the operation of the keyboard of the first mobile phone 1 by the user. In the telephone number column of the telephone directory 10, Mr. A's telephone number, Mr. B's telephone number, and Mr. C's telephone number are recorded by the user operating the keyboard of the first mobile phone 1. In the mail address column of the telephone directory 10, Mr. A's mail address, Mr. B's mail address, and Mr. C's mail address are recorded by the user operating the keyboard of the first mobile phone 1. Further, the own telephone number and mail address of the first mobile phone 1 are also recorded in the telephone directory 10.

  In this way, when the communication carrier determination unit 9 uses the domain of the mail address recorded in the second portable communication carrier column 25 as the communication carrier specifying information (hereinafter, the domain of the mail address is referred to as a domain), The telephone number input by the communication carrier determination unit 9 is collated with the telephone book 10, and the domain of the mail address extracted from the telephone book 10 corresponding to the telephone number (hereinafter, the domain of the mail address is referred to as a domain). Phone number portability that allows the user to change the carrier without changing the phone number if it is determined whether the carrier is the same using the domain recorded in the second portable carrier column 25 There is an advantage that it is possible to accurately determine whether or not the carriers are the same even under the operation of

  With reference to FIG. 3, a communication carrier determination process for determining whether or not a communication carrier is the same depending on the domain will be described. This communication carrier determination process is performed by the communication carrier determination unit 9 of FIG. The processing in steps 106 to 108 in FIG. 3 corresponds to the processing in step 101 in FIG. 1, and the processing in steps 102 to 105 in FIG. 3 is the same as the processing in steps 102 to 105 in FIG.

  In FIG. 3, when the communication carrier determination process starts, it is determined in step 106 whether or not a telephone number is input. When the input of the telephone number of the communication partner is completed, step 106 becomes YES and the process proceeds to step 107. In step 107, the telephone number of the communication partner input is collated with the telephone book 10 of FIG. 2, the domain corresponding to the telephone number of the communication partner input from the telephone book 10 is extracted, and the process proceeds to step 108. In step 108, the communication carrier of the communication partner is specified from the extracted domain, and the process proceeds to step 102.

  3, for example, when the communication partner is Mr. A shown in FIG. 2, the domain “pdx.ne.jp” is extracted as information specifying the communication carrier. 2 is extracted as information for specifying the communication carrier, for example, when the communication partner is Mr. C shown in FIG. 2, the domain “ghi.ne.jp” is extracted. jp "is extracted as information specifying the communication carrier.

  Next, a specific example (1) to a specific example (3) in the case where a communication path is formed by the communication carrier determination process will be described with reference to FIG.

  In the specific example (1), the domain recorded in the telephone directory 10 of FIG. 2 as the first mobile phone 1 is “pdx.ne.jp” and is recorded in the second mobile communication operator column 25. This is a case where the domain is “xyz.ne.jp” and the communication partner domain extracted in step 107 in FIG. 3 is “pdx.ne.jp”. Therefore, the domain “xyz.ne.jp” in the second mobile communication operator column 25 is different from the communication partner domain “pdx.ne.jp”, the communication partner domain “pdx.ne.jp” and the user Domain “pdx.ne.jp” is the same. As a result, the first mobile phone 1 is communicably connected to the first communication carrier compatible mobile phone 21 via only the first communication carrier communication network 15.

  In the specific example (2), the own domain is “pdx.ne.jp”, the domain recorded in the second portable communication carrier column 25 is “xyz.ne.jp”, and the steps of FIG. This is a case where the domain of the communication partner extracted in 107 is “xyz.ne.jp”. Therefore, the domain “xyz.ne.jp” in the second portable communication operator column 25 and the domain of the communication partner are “ xyz.ne.jp "is the same. As a result, the first mobile phone 1 is connected to the first Bluetooth transmitting / receiving unit 5 through the second Bluetooth transmitting / receiving unit 13, the second mobile transmitting / receiving unit 12, and the second communication carrier communication network 16. 2 It is connected to the communication carrier compatible mobile phone 22 so as to be communicable.

  In the specific example (3), the own domain is “pdx.ne.jp”, the domain recorded in the second portable communication operator column 25 is “xyz.ne.jp”, and the steps of FIG. This is a case where the domain of the communication partner extracted in 107 is “ghi.ne.jp”. Therefore, the domain “xyz.ne.jp” of the second portable communication operator column 25 is different from the communication partner domain “ghi.ne.jp”, and the communication partner domain “ghi.ne.jp” is different from the domain “ghi.ne.jp”. My domain is different from “pdx.ne.jp”. As a result, the first mobile phone 1 communicates with the communication partner of Mr. C who is the communication partner from the first mobile transceiver 4 via the first communication carrier communication network 15, the gateway switch 18 and the separate communication carrier communication network 17. Connected to the mobile phone 23 corresponding to the person.

“Embodiment 2”
5 is different from the first embodiment shown in FIGS. 1 to 4 in that the communication carrier has a plurality of domains. As shown in FIG. 5a, for example, the communication carrier owns the domains “xyz.ne.jp” and “dxyz.ne.jp”, and the communication carrier Y has “ghi.ne.jp” and A case where a domain “fghi.ne.jp” is owned is illustrated.

  Then, as shown in FIG. 5 b, the user operates the keyboard of the first mobile phone 1 to display “xyz.ne.jp” and “dxyz” in the second mobile communication operator column 25 of the flash memory 7. .Ne.jp "is recorded. Further, the name of Mr. D, the phone number of Mr. D, and the mail address of Mr. D are additionally recorded in the telephone directory 10.

  Therefore, in FIG. 5b, for example, when the user operates the keyboard of the first mobile phone 1 and inputs the phone number of Mr. B or Mr. D, the communication carrier determination unit 9 sets the second mobile communication business. The second telecommunications carrier is specified as the telecommunications carrier from the domain “xyz.ne.jp” or the domain “dxyz.ne.jp” recorded in the operator column 25, and as a result, the first mobile phone 1 shown in FIG. The second Bluetooth carrier of Mr. B or D who is the communication partner via the first Bluetooth transmitter / receiver 5 to the second Bluetooth transmitter / receiver 13, the second mobile transceiver 12 and the second carrier communication network 16 The mobile phone 22 is communicably connected.

“Embodiment 3”
In FIG. 6, what is different from the first embodiment shown in FIGS. 1 to 4 is that one telecommunications carrier has a plurality of domains and has an integrated domain in which the plurality of domains are unified. As shown in FIG. 6a, for example, a carrier that owns the domain “xyz.ne.jp” and the domain “dyz.ne.jp” owns the integrated domain “xy.ne.jp”, and the domain The case where the communication carrier Y that owns “ghi.ne.jp” and the domain “fghi.ne.jp” owns the integrated domain “ggh.ne.jp” is illustrated.

  Then, as shown in FIG. 6b, the user operates the keyboard of the first mobile phone 1 to record the integrated domain “xy.ne.jp” in the second mobile communication operator column 25 of the flash memory 7. Let In addition, when the user records Mr. B's mail address or Mr. D's mail address in the mail address column of the telephone directory 10, the user can confirm the integrated domain from the chart shown in FIG. B's mail address “abc@xxx.ne.jp” including “.ne.jp” is recorded, and D's mail address “abc@xxx.ne.jp” including the integration domain “xy.ne.jp” is recorded. To record.

  For example, in the state where the integrated domain “xy.ne.jp” is recorded in the second mobile communication operator column 25 as shown in FIG. 7, the user tries to call Mr. B or Mr. When the telephone number of Mr. B or Mr. D is entered by operating the keyboard of the telephone 1, the communication carrier determination unit 9 makes the domain “xyz.ne.jp” or Mr. D from the mail address column of the telephone book 10. The integrated domain “xy.ne.jp” is extracted from the domain table 27 based on the domain “dxyz.ne.jp”.

  Then, it is the second communication carrier from the integration domain “xy.ne.jp” extracted from the domain setting unit 26 and the integration domain “xy.ne.jp” recorded in the second portable communication operator column 25. As a result, the first mobile phone 1 shown in FIG. 1 is switched from the first Bluetooth transmission / reception unit 5 to the second Bluetooth transmission / reception unit 13, the second portable transmission / reception unit 12, and the second communication carrier communication network 16. The communication partner is connected to the mobile phone 22 corresponding to the second communication carrier of Mr. B or D who is the communication partner.

  With reference to FIG. 8, a communication carrier determination process for determining whether or not a communication carrier is the same according to the integrated domain will be described. This communication carrier determination process is performed by the communication carrier determination unit 9 of FIG. 8 are the same as steps 102 to 105 and steps 106 and 107 in FIG. 3, and steps 109 and 110 in FIG. 8 are newly provided. It is processing. Step 109 is a process of extracting an integrated domain from the domain table 27 of FIG. Step 110 is a process of specifying a communication carrier from the integrated domain instead of step 108 in FIG.

  In FIG. 8, the communication carrier determination process starts, the last input of the telephone number of the communication partner is completed, and step 106 becomes YES. In step 107, the telephone number of the communication partner input is collated with the telephone book 10 of FIG. 7, the domain corresponding to the telephone number of the communication partner input from the telephone book 10 is extracted, and the process proceeds to step 109. In step 109, the extracted domain is collated with the domain table 27 of FIG. 7, the integrated domain is extracted from the domain table 27, and the process proceeds to step 110. In step 110, the communication carrier of the communication partner is specified from the extracted integrated domain, and the process proceeds to step 102. Subsequent processing is the same as in FIG.

  8, for example, when the communication partner is Mr. B or Mr. D shown in FIG. 7, the integrated domain “xy.ne.jp” identifies the communication carrier from the domain table 27. For example, in the case where the communication partner is Mr. C shown in FIG. 7, the integrated domain “ggh.ne.jp” is extracted from the domain table 27 as information specifying the communication carrier.

“Embodiment 5”
9 differs from the fourth embodiment shown in FIG. 6 in that the path specifying unit 28 and the accounting table 29 are provided in the flash memory 7. The path specifying unit 28 is embodied by a program stored in the flash memory 7. The billing table 29 is a data table that defines the relationship between the telecommunications carrier, time, and call charge. In the billing table 29, for example, the user operates the keyboard of the first mobile phone 1 to record the name of the communication carrier, the time, and the call charge.

  In the billing table 29, for example, from 21:00 to 9 o'clock for a communication carrier, 20 yen is recorded for 30 seconds for the same communication carrier and 18 yen for 30 seconds for another communication carrier. From 9 am to 9 pm, it is recorded as 30 yen for 30 seconds for the same telecommunications carrier and 33 yen for 30 seconds for another telecommunications carrier, from 2 pm to 9 am for the telecommunications carrier Y Is recorded as 18 yen for 30 seconds in the case of the same carrier, and 19 yen for 30 seconds in the case of another carrier, and 30 for the same carrier from time 9 to 21:00 for the carrier Y. The case where it is recorded as 35 yen for 30 seconds in the case of another communication carrier at 32 yen per second is illustrated.

  Then, in the state where the integrated domain “xy.ne.jp” is recorded in the second mobile communication operator column 25 as shown in FIG. 9, the user operates the keyboard of the first mobile phone 1 and Mr. B or When Mr. D's telephone number is input, the communication carrier determination unit 9 identifies the communication carrier X from the integrated domain “xy.ne.jp” recorded in the second portable communication carrier column 25. Further, the route specifying unit 28 specifies the communication route from the charging table 29 based on the input time and fee of the telephone number for each communication carrier.

  Referring to the billing table 29, for example, when the input time of the telephone number is between 21:00 and 9:00, the same carrier charge is 20 yen for 30 seconds and another carrier charge is 18 seconds for 30 seconds. The communication carrier Y has another communication carrier fee of 19 yen for 30 seconds. Therefore, the path specifying unit 28 uses the same carrier charge for the communication carrier as 20 yen for 30 seconds, 18 yen for 30 seconds as another carrier charge, and 19 seconds for 30 seconds as another charge for the carrier Y. Compared with the circle, the carrier X is specified as a communication path as a low-priced carrier.

  As a result, the telecommunications carrier X specified by the telecommunications carrier determination unit 9 and the telecommunications carrier X specified by the route specifying unit 28 match, so the first mobile phone 1 shown in FIG. Communicating from the unit 5 to the second communication carrier compatible mobile phone 22 of Mr. B or D who is the communication partner via the second Bluetooth transmission / reception unit 13, the second portable transmission / reception unit 12, and the second communication carrier communication network 16.

It is 33 yen per second, and another telecommunications carrier fee for carrier Y is 29 yen for 30 seconds. Therefore, the route specifying unit 28 has the same carrier charge of 30 seconds for 30 seconds and 33 yen for 30 seconds of another carrier charge for 30 seconds and 29 seconds for 30 seconds of another charge of carrier charge for the communication carrier Y. Compared with the circle, the carrier Y is specified as a communication path as a low-cost carrier.

  The charging table 29 may be registered in the flash memory 7 when the first mobile phone 1 is shipped from the factory, and may be updated manually by the user of the first mobile phone 1 each time. When the mobile phone 1 is shipped from the factory, it is not registered in the flash memory 7 and may be input manually by the user each time. Furthermore, the billing table 29 may be updated on-line from, for example, the homepage of the telecommunications carrier that registers the first mobile phone 1 in addition to the manual update as described above.

  And although the communication carrier X specified by the communication carrier determination unit 9 and the communication carrier Y specified by the route specifying unit 28 are different, the result is that the low-priced communication carrier Y specified as the communication route is given priority. The first mobile phone 1 shown in FIG. 1 is connected from the first mobile transceiver 4 to the first communication carrier communication network 15, the gateway exchange 18, another communication carrier communication network 17, the gateway exchange 19, and the second communication carrier communication. Via the network 16, the communication partner B is connected to the second communication carrier compatible mobile phone 22 of Mr. B or C.

  With reference to FIG. 10, a communication carrier determination process and a path identification process for determining whether or not a communication carrier is the same by an integrated domain will be described.
