Description

  The present invention relates to an information communication terminal with a communication network selection function capable of selecting a communication network corresponding to a selected transmission number, and a communication network selection method for selecting a communication network corresponding to a selected transmission number.

  Due to the remarkable development of information communication technology in recent years, it has become possible for information communication terminals to use not only a specific communication network but also a plurality of communication networks.

  Also, a method has been conventionally disclosed in which an information communication terminal that can use a plurality of information communication networks uses a plurality of communication networks depending on the situation.

  For example, there is an information communication terminal that can use a plurality of communication methods, and when a telephone number is selected and transmitted, there is a telephone communication device that transmits with a communication method type associated with the telephone number.

  For example, first, when registering in the telephone directory, the communication method type is registered in association with the telephone number. Next, when selecting a telephone number and making a call, the registered content of this communication method type is compared with the communication method type of the terminal itself, and the call is made according to the communication method registered in association with the telephone number to be sent There is a telephone communication device (see Japanese Patent Laid-Open No. 2000-049961).

  In addition, there is a wireless communication apparatus that performs communication by connecting to an optimal communication network by identifying a carrier identification code assigned to a communication carrier included in the telephone number itself (Patent Document 2: Japanese Patent Laid-Open No. 2000-2000) No. 156880).

  Furthermore, there is an information communication terminal that can be used by both a PBX network that can be used by connecting to a PBX using an actually built-in wireless LAN and a mobile communication network that can be used as a normal information communication terminal. Has come out on the market.

  However, when using a plurality of communication networks, it has been difficult to arbitrarily set which communication network to use for a specific destination.

  This is because the telephone communication device described in Patent Document 1 sets a specific communication network for a specific telephone number at the time of telephone directory registration. For this reason, when making a call to a specific telephone number, a communication network registered in the telephone directory is used.

  Alternatively, the wireless communication device described in Patent Document 2 selects a communication network to be used by identifying a carrier identification code included in the telephone number itself at the time of outgoing call. For this reason, it is impossible for the caller to arbitrarily select a communication network.

  In addition, when an information communication terminal having a call button corresponding to a plurality of communication networks is used, since a call button corresponding to each communication network is provided, a communication network corresponding to this telephone number is once entered after entering a telephone number. When a different call button is pressed, a call error occurs and the operation becomes complicated.

  Therefore, the present invention has been made in view of the above circumstances, and an object of the present invention is to easily select and access a base station connected to each of a plurality of wireless communication networks with a simple operation.

  Further, the communication network selection method of the present invention is an identification including information for accessing a specific communication network in a communication network selection method using an information communication terminal connectable to a plurality of communication networks via a base station. Storing information, comparing whether the identification information is included in the input information received at the time of transmission, and if included, communicating with the first base station connected to the specific communication network, When not included, it has a control means to communicate with a second base station connected to another communication network.

  The communication network selection method of the present invention and the information communication terminal using the communication network selection method can communicate with a plurality of communication networks, and which of these communication networks is to be used. Data having a list form of identification codes for determination.

  As a result, when a user makes a call to a certain party including an identification code for selecting a communication network in addition to the destination telephone number information, the user refers to the identification code table in the information communication terminal. By connecting to the corresponding communication network, the user can easily communicate using any communication network.

  FIG. 2 is a block diagram of a communication network system showing an embodiment of the present invention.

  FIG. 2 shows an image of a base station A16, a base station B15, and a communication network connectable from these base stations as this communication network system.

  As shown in FIG. 2, the communication network system according to the embodiment of the present invention includes a communication path in which a terminal 1 is connected to a mobile communication network 17 via a base station A16, a base station B15, and the base station And a communication path connected to the PBX network 13 via a PBX (private branch exchange) 14.

  Note that the mobile communication network 17 shown in FIG. 2 can communicate with a public network, a wired communication network, a general telephone line network, and the Internet network.

  The base station A16 is, for example, a base station for accessing the mobile communication network 17, and is connected to the public communication network and the Internet network as well as the mobile communication network 17 via the base station A16. Communication.

  The base station B15 is, for example, a wireless LAN access point (referred to as an AP), and the terminal 1 that has accessed the AP communicates with the PBX 14 so that the function of the PBX 14 allows the PBX network 13, public network, It becomes possible to communicate with the mobile communication network 17 and the Internet network.

  Note that the mobile communication network here may be either a PDC (Personal Digital Cellular) system or a CDMA2000 (Code Division Multiple Access 2000) system. Of course, a mobile communication network of other communication methods may be used.

  Here, the specific communication network indicates the PBX network 13, while the other communication networks include the mobile communication network 17, the public network, the priority communication network, and the general telephone line network.

  FIG. 3 is an image diagram of the areas of base station A16 and base station B15 according to the embodiment of the present invention.

  The areas shown in FIG. 3 are base stations A16 that can be used only by the mobile communication network 17 and bases that can only be used by the area A18 (the hatched portion on the right in FIG. 3) and the PBX network 13 (private branch exchange network). Area B19 of station B15 (the downward slanted line portion in FIG. 3), area C20 in which both base stations can be used (crossed hatched portion in FIG. 3), and area D21 in which both base stations cannot be used (white in FIG. 3) Part).

  The areas of the base station B15 connected to the PBX network 13 (area B19, area C20 in FIG. 3) are areas in which the terminal 1 can access the base station B15, and are located on the company floor, for example.

  The areas of the base station A16 connected to the mobile communication network 17 are the areas A18 and C20 in FIG. 3, and the areas outside the areas of the base stations A16 and B15 (area D21 in FIG. 3) An area that is inaccessible to the station A16 and the base station B15 is shown, for example, an underground mall.

  Next, communication network identification information according to the embodiment of this invention will be described.

  The communication network identification information is stored in the communication network identification information storage unit 51 of the memory 5.

  FIG. 4 is an image diagram of the communication network identification information storage unit 51.

  The communication network identification information storage unit 51 holds communication network identification information 52 necessary for accessing the base station B15.

  In the terminal 1 according to the embodiment of the present invention, the necessary transmission code for accessing the base station B is “8” in the case of extension communication that is PBX network communication, or outside line communication that is communication outside the PBX network ( “1” in the case of public network or communication for a mobile communication network). Based on this, in FIG. 4, “8” is held as the extension transmission code and “1” is held as the outside transmission code as the network identification information 52.

  Here, the extension code is a code used for an extension telephone number (hereinafter referred to as an extension number) when performing extension communication within the PBX network via the base station B15. This is information to be added to the telephone number when performing extension communication from the PBX network 13 via.

  That is, the user makes a call with the terminal 1 by adding a number indicating the extension call code, for example, a number “8” to the head of the destination telephone number.

  On the other hand, the external line transmission code is a code used when connecting to the mobile communication network 17 shown in FIG. 2, the public network, or the general telephone line network, and is connected to the PBX network via the base station B15. 13 is information to be added to the telephone number when performing external line communication.

  Similarly to the extension transmission code, the user makes a call at the terminal 1 by adding a number indicating the external transmission code, for example, a number “1” to the head of the destination telephone number.

  Here, “1” is used as the external transmission code and “8” is used as the internal transmission code. However, other numbers or two or more digits may be used.

  The control unit 11 selects which base station is to be accessed by comparing whether or not a transmission code is added to the head of the input number received at the time of transmission with this communication network identification information 52.

  When a transmission code is received from the terminal 1 via the base station B15, the PBX 14 connected to the base station B15 determines whether the transmission code received from the terminal 1 is an outside line communication or not. Therefore, it is determined whether the communication is extension communication, and communication is performed with respect to the optimum communication network.

  For example, when an extension number and an extension transmission code are used, communication is possible by connecting to the PBX network 13 using the PBX 14. When a call is made to an outside line number that is also a telephone number for a normal public network using an outside line call code, the call is sent from the PBX network 13 to the public network using the PBX 14.

  In addition to the communication network identification information 52, the communication network identification information storage unit 51 also holds related information 53 that is information related to the communication network identification information 52. The related information 53 includes, for example, history information indicating an input number for each caller and the number of digits of the phone number of the callee.

  FIG. 5 is an image diagram showing the related information 53 as a list.

  The top row of FIG. 5 shows the names of counterparts for a plurality of names (in this case, four names are shown here), and the leftmost column indicates items of related information 53 used for communication network identification. . Here, the item of the related information 53 is shown as history information or the number of digits of the telephone number of the call destination. However, as long as the information is related to the communication network identification information 52, the information is not limited to the two.

  History information is a normal phone number, extension number, or number information entered using an extension call code or extension call code, etc., so far, the user corresponds to the other party name shown in the upper part of the list of FIG. It holds input information made to make a call to the other party.

  The number of digits of the telephone number holds information on the number of digits of a telephone number (either an outside line number or an extension number is acceptable) indicating the other party.

  For example, when the name of the other party in FIG. 5 is “Ata Sato”, “8-10-23310” is held in the history information item as input information input in the past. Also, “7” indicating the number of digits “10-23310” indicating the extension number is held as the number of digits of the telephone number. In the case of “Ito Biko”, “1-03-111-2222” is held in the history information item, and “10-111-2222” indicating the number of the outside line as the number of digits of the telephone number “10” Is retained.

  When the number of digits of the input information input at the time of outgoing call is one digit greater than the number of digits of the telephone number in the related information, the control unit 11 can determine that the outgoing code is added. .

  As described above, the history information and the number of digits of the telephone number included in the related information 53 are, for example, when the control unit 11 determines whether or not a transmission code is added when making a call at the terminal 1. It can also be used as a discrimination material.

  That is, the related information 53 of “Sato A Ta” and “Ito Bko” shown in the related information 53 of FIG. 5 has the same number of digits of the “history information” number that is held as “phone”. One more than the value of “Number of digits”. For this reason, the control unit 11 determines that the number at the beginning of the transmission number held in each “history information” indicates “8” or “1” of the transmission code.

  Thereby, the control part 11 connects to base station B15, respectively, when it transmits using the transmission number currently hold | maintained in these log | history information.

  On the other hand, the related information 53 of “Yamada Cuo” and “Suzuki Dmi” has the same number of digits of the number of “history information” retained as the value of the “number of digits of the telephone number” retained. Therefore, the control unit 11 can determine that the telephone number held in these “history information” does not have a transmission code.

  Next, creation of communication network identification information 52 and related information 53 created in the communication network identification information storage unit will be described.

  For example, when creating a telephone book of a destination, the control unit 11 extracts data for telephone book creation that has been accepted as necessary. By outputting the extracted data to the corresponding item of the communication network identification information 52 of the corresponding counterpart, the communication network identification information 52 is created in the communication network identification information storage unit 51.

  At the time of creation, the control unit 11 provides a field for inputting history information and information indicating the number of digits of the telephone number as the related information 53 shown in FIG. To do.

  Further, the user may arbitrarily create the communication network identification information 52 via the operation unit 9.

  The transmission code may be arbitrarily input by the user when creating the communication network identification information 52, or may be output by the control unit 11 based on information obtained when communicating with the base station B15. Absent.

  Next, processing when the terminal 1 performs a transmission operation will be described.

  FIG. 6 is a flowchart showing processing when the terminal 1 performs a call origination operation in the communication network system according to the embodiment of this invention.

  First, it is assumed that the control unit 11 detects in advance by communication whether the PBX network 13 can be used periodically before the call operation and before the call button 91 is pressed.

  The user selects the destination telephone number from the memory 5 of the terminal 1 or inputs the destination telephone number via the operation unit 9, and then displays the destination number on the display unit 10. Then, the call button 91 is pressed (S51).

  Alternatively, after the user presses the call button 91, the user can perform a call operation by directly inputting the callee number from the operation unit 9 or displaying the phonebook data on the display unit 10. Good.

  The control unit 11 that has received the transmission instruction from the user determines whether the base station B15 is currently accessible based on the communication result detected in advance (S52).

If access to the base station B15 is impossible, that is, if the terminal 1 is outside the wireless LAN area (No in S52), that is, if it is the area A18 or the area D21, is it possible to access the base station A16 next? Is detected (S53).
When the access to the base station A16 is not possible, that is, in the case of the area D that is outside the usable area of the normal information communication terminal (No in S53), the terminal 1 uses the public network and the mobile communication network 17 The control unit 11 displays “cannot make a call” on the display unit 10, assuming that communication with both the base station A16 to perform communication and the base station B15 to use the PBX network 13 is impossible (S54). For example, the user is notified that the call cannot be made.

  When it is possible to access the base station B15, that is, when the terminal 1 is present in either the area B19 or the area C20 (Yes in S52) and when the base station A16 is accessible (Yes in S53), the control unit 11 compares the input information input from the operation unit 9 with the communication network identification information 52 registered in the communication network identification information storage unit 51 (S55).

  At this time, the control unit 11 can perform comparison using not only the communication network identification information 52 but also the related information 53.

  As a result of the comparison, if the input information includes an external line transmission code or an internal line transmission code that is the communication network identification information 52 (Yes in S56), the control unit 1 sends the base station B15 to the radio communication unit 3. An instruction to access is given (S57). Thereby, the terminal 1 starts communication with the PBX network 13.

  That is, in the case of the telephone numbers shown in the history information of “Sato A-ta” and “Ito B-ko” shown in FIG. 5, since they have the outgoing codes “8” and “1”, they access the base station B15. To do.

  On the other hand, as a result of comparison, if the input information at the time of transmission does not include a transmission code that matches the external transmission code or the internal transmission code held as the communication network identification information 52 (No in S56), the control unit 11 instructs the wireless communication unit 3 to access the base station A16 using the telephone number displayed on the display unit 10 (S58). Thereby, the terminal 1 starts communication with the mobile communication network 17 and the public network.

  That is, it is the case of the telephone numbers shown in the history information of “Yamada C male” and “Suzuki D beauty” shown in FIG.

  As a result, even if the terminal 1 can use a plurality of communication networks, any communication network can be selected according to the presence / absence of a transmission code to be input simultaneously and the type of the transmission code when a telephone number is input. Can be selected.

  For this reason, it becomes possible to easily select a specific communication network from a plurality of communication networks for the same telephone number in accordance with the user's preference.

  Next, the terminal according to the second embodiment of this invention will be described.

  FIG. 7 is a block diagram illustrating a configuration of the terminal 1 ′ according to the second embodiment. All except the touch panel type operation unit 10 ′ are the same, but the numbers are given with “′”.

  The transmission code included in the communication network identification information 52 ′ of the terminal according to the second embodiment of the present invention is indicated by an icon mark instead of numerical information.

  In addition, the user inputs information on the outgoing code and the telephone number using the numeric keypad 92 of the operation unit 9 in the terminal 1 of the first embodiment.

  On the other hand, in the terminal 1 of the second embodiment, after touching the icon mark displayed on the touch panel type display unit 10 ′ of the terminal 1 ′, the telephone number of the other party is displayed using the numeric keypad. input.

  That is, the difference from the terminal 1 of the first embodiment is that an icon mark is used instead of the outgoing code and that the display unit 10 is replaced with a touch panel display unit 10 ′. The touch panel type display unit 10 ′ is a display unit that can be input by touching the displayed content, and also serves as an operation.

  FIG. 8 is an image diagram of the communication network identification information 52 ′ according to the second embodiment.

  The difference is that an icon mark is shown instead of a number in the column indicating the outside line transmission code and the extension line transmission code.

  When the user makes a call using the terminal 1 ′, after touching the icon mark designated by the communication network identification information 52 ′ among the plurality of icon marks displayed on the touch panel display unit 10 ′, The telephone number indicating the desired destination is entered using the numeric keypad.

  Thereafter, by pressing the transmission button 91, the control unit 11 ′ can access the base station B15 and communicate with a desired transmission destination.

  For example, when the name of the call destination is “Hanako Yamada”, the user can select “factory mark” or “mobile phone mark” displayed on the touch panel display unit 10 ′ after or before pressing the telephone number. Assume that you touched the “Factory Mark” icon mark.

  Based on the received input information, the control unit 11 indicates that the destination is “Yamada Hanako”, the output information from the touch panel display unit 10 ′ is “factory mark”, and is compared with the communication network identification information 51. It is detected that the process should be transmitted via the PBX network 13.

  Based on this detection content, the control unit 11 accesses the base station B15.

  On the other hand, when the “mobile phone mark” icon mark is touched, the control unit 11 indicates that the destination is “Hanako Yamada” based on the received input information, and the output information from the touch panel display unit 10 ′ As a result of comparison with the communication network identification information 51, it is detected that the process should be transmitted via the mobile communication network 17.

  Based on this detection content, the control unit 11 accesses the base station A16.

  As described above, in the communication network selection method according to the second embodiment and the terminal 1 using this selection method, it is possible to prevent mistakes in the transmission operation by replacing the transmission code with visual information. .
