  According to the present invention, it is possible to quickly establish a communication path between a calling telephone terminal and a receiving telephone terminal via a specific relay station with a changed telephone number without any trouble.

  The best mode for carrying out the present invention will be described according to the first and second embodiments.

  The first embodiment is an example realized by providing a communication path establishing device separately from the calling side telephone terminal and connecting the communication path establishing device to the calling side telephone terminal.

  First, a configuration example of the first embodiment is shown in a block diagram in FIG. The calling-side telephone terminal 10 has a display 12 capable of displaying information such as input data and transmission / reception data, and storage means 14 for storing a specific station telephone number 14a and an incoming telephone number 14b. The incoming side telephone terminal 30 is assigned an incoming telephone number 14b, and the specific relay station 20 is assigned a specific station telephone number 14a. The originating side telephone terminal 10, the terminating side telephone terminal 30, and the specific relay station 20 are all connected to the communication network N or in a connectable state. The origination side telephone terminal 10 and the destination side telephone terminal 30 may be any type, for example, a mobile telephone, a fixed telephone, or a computer (so-called IP telephone) configured to be able to talk. The same applies to the specific relay station 20, and not only the relay station and the base station but also a telephone or the like may be used. The communication network N may be a telephone network or the Internet regardless of the type.

The communication path establishment device 16 is configured to be connectable to the calling side telephone terminal 10 and includes a first calling means 16a, a second calling means 16b, a selection means 16c, and a storage means 16d. The first calling means 16a makes a call using the specific station telephone number 14a stored in the storage means 14 as a calling number. When the second calling means 16b detects that the communication path is established between the calling telephone terminal 10 and the specific relay station 20 by the first calling means 16a, the incoming telephone number stored in the storage means 14 Call 14b as the calling number. The selecting means 16c selects one incoming telephone number 14b for establishing a communication path from among a plurality of incoming telephone numbers 14b stored in the storage means 14. Each of these first calling means 16a, second calling means 16b, and selection means 16c implements each function by executing a program. The storage means 16d stores the caller telephone number of the caller telephone terminal 10 that can be connected.
Both the specific station telephone number 14 a and the incoming telephone number 14 b may be stored in the storage unit 14 of the calling telephone terminal 10. If at least one of the specific station telephone number 14a and the incoming telephone number 14b changes, the telephone number after the change can be easily and quickly changed without applying to the relay station as in the past. Can be used.

  Flow control for establishing a communication path between the originating side telephone terminal 10 and the terminating side telephone terminal 30 in the above configuration will be described with reference to FIGS. Between FIG. 2 and FIG. 3, the processing continues through connectors A, B, C, D, and E, respectively.

  The communication path establishment device 16 is connected to the caller side telephone terminal 10 by inserting a connector or the like. The communication path establishment device 16 that has detected this connection requests the calling telephone terminal 10 for its own telephone number (that is, the calling telephone number) (S1), and in response to this request, the calling telephone terminal 10 Replies with its own telephone number to the communication path establishment device 16 (S2).

  The communication path establishment device 16 compares the telephone number returned from the communication path establishment device 16 with the telephone number stored in the storage means 16d (S3). If the telephone numbers do not match (NO), the subsequent processing is not performed. On the other hand, if the telephone numbers match (YES), the processing is divided depending on whether or not the address of the storage means 14 for storing the telephone number is fixed (S4). The above-mentioned telephone number and the like are the telephone number of the specific relay station 20 (namely, the specific station telephone number 14a), the telephone number of the destination telephone terminal 30 (namely, the incoming telephone number 14b), and the authentication for receiving authentication by the specific relay station 20 At least one of the symbols 14c corresponds.

  If at least one address is not fixed in S4 (NO), the communication path establishment device 16 requests the calling side telephone terminal 10 to input the address (S5). In response to this input request, the user inputs data such as an address or a telephone number by using a key provided in the calling side telephone terminal 10. Keys corresponding to the operation unit can input numbers from “0” to “9” and symbols such as “#” and “*”. When inputting the address of the storage means 14, the user needs to store one or more cases for the specific station telephone number 14a and the incoming telephone number 14b in the corresponding addresses. When the user finishes inputting data, the calling side telephone terminal 10 returns the input data to the communication path establishment device 16 (S6). The communication path establishment device 16 stores the answered data in the storage unit 16d.

  On the other hand, when all addresses are fixed in S4 (YES), the process proceeds to S7 as it is. As a fixed example of the address, the address of the specific station telephone number 14a is set to “000 address”, the address of the incoming telephone number 14b is set to “001 address”, and the address of the authentication code 14c is set to “002 address”. To do. If the communication path establishment device 16 is configured so that the user can set each address, the degree of freedom in setting the telephone number and the like increases.

  Next, the processing is divided depending on whether the data input by the user is an address (S7). For example, if the content of the input data is 3 digits or less, it is determined as an address, if it is 8 digits or more, it is determined as a telephone number, and if it is any other number, re-input is requested. If it is determined as an address in S7 (YES), the communication path establishment device 16 requests the content stored in the address to the calling side telephone terminal 10 (S8), and the calling side telephone terminal 10 responds to this request. The contents stored at the designated address are returned to the communication path establishment device 16 (S9). The content of the address is information stored by the user and is a telephone number or an authentication code. The communication path establishment device 16 responds to the specific station telephone number 14a, the incoming telephone number 14b, and the authentication code 14c, respectively, from the telephone number returned from the calling telephone terminal 10 in S6 or from the calling telephone terminal 10 in S9. The telephone number is specified and stored in the storage unit 16d.

  In order to establish a communication path between the calling side telephone terminal 10 and the specific relay station 20, the communication path establishment device 16 requests the calling side telephone terminal 10 to make a call using the specific station telephone number 14a as the calling number. In response to this request (S10), the originating telephone terminal 10 issues a call with the specific station telephone number 14a as the originating number (S11). The specific relay station 20 that has received the call returns a call signal to the caller telephone terminal 10 (S12), and the caller telephone terminal 10 that has received this call signal transmits call signal information indicating that the call signal has been received to the communication path. This is transmitted to the establishment device 16 (S13).

  Moving to FIG. 3, the process waits until a communication path is established between the calling side telephone terminal 10 and the specific relay station 20 (S14). When a communication path is established between the originating side telephone terminal 10 and the specific relay station 20 in S14 (YES), the specific relay station 20 determines whether or not to permit a call to the incoming side telephone terminal 30. The caller side telephone terminal 10 requests an authentication code (S15), and the caller side telephone terminal 10 receiving this request transmits the authentication code information indicating that the authentication code is requested to the communication path establishment device 16 ( S16). Receiving the authentication code information, the communication path establishment device 16 reads the authentication code 14c from the storage means 16d and answers it to the caller telephone terminal 10 (S17). (S18). The authentication code 14c stored in the storage unit 14 corresponds to an identification code such as “# 12 #” or a personal identification number such as “0123”.

  The specific relay station 20 determines whether the returned authentication code matches a preset authentication code (S19). If the two authentication codes do not match in S19 (NO), the communication path established between the calling telephone terminal 10 and the specific relay station 20 is not permitted without making a call to the receiving telephone terminal 30. Cut and finish the process.

  On the other hand, if the two authentication codes match in S19 (YES), the call to the receiving side telephone terminal 30 is permitted. For this purpose, the specific relay station 20 requests an incoming telephone number from the originating telephone terminal 10 (S20), and the originating telephone terminal 10 that has received this request receives incoming telephone number information indicating that the incoming telephone number has been requested. Is transmitted to the communication path establishment device 16 (S21). Receiving the incoming telephone number information, the communication path establishment device 16 reads the incoming telephone number 14b from the storage means 16d and answers it to the calling telephone terminal 10 (S22). This is transmitted to the station 20 (S23).

  The specific relay station 20 that has received the transmission of the incoming telephone number 14b makes a call with the incoming telephone number 14b as the outgoing number (S24), and the incoming telephone terminal 30 that has received the outgoing call sends a call signal to the specific relay station 20 Return (S25). It waits until a communication path is established between the specific relay station 20 and the receiving side telephone terminal 30 (S26). When a communication path is established between the specific relay station 20 and the receiving side telephone terminal 30 in S26 (YES), the specific relay station 20 establishes a communication path between the calling side telephone terminal 10 and the receiving side telephone terminal 30. The telephone call is made possible (S27).

According to the first embodiment described above, the following effects can be obtained.
(A1) The communication path establishment device 16 includes a first calling unit 16a and a second calling unit 16b (see FIG. 1). The first calling means 16a makes a call using the specific station telephone number 14a stored in the storage means 14 as a calling number (see FIG. 2; S10, S11), and the second calling means 16b is stored in the storage means 14. The incoming telephone number 14b is called as a calling number (see FIG. 3; S22, S23). The specific station telephone number 14a and the incoming telephone number 14b need only be changed and stored in the storage means 14 of the calling telephone terminal 10. If at least one of the specific station telephone number 14a and the incoming telephone number 14b changes, the telephone number after the change can be easily and quickly changed without applying to the relay station as in the past. Can be used. Therefore, it is possible to quickly establish a communication path to the receiving side telephone terminal 30 via the specific relay station 20 with the changed telephone number without any trouble (see FIG. 3; S27).

(A2) When a plurality of incoming telephone numbers 14b are stored in the storage means 14, the address of the incoming telephone number 14b to be communicated by establishing a communication path is input at the outgoing side telephone terminal 10 Is selected (corresponding to the selection means 16c). In this example, one incoming telephone number 14b is selected in accordance with the form of inputting an address. However, a configuration in which a plurality of incoming telephone numbers 14b are displayed in a menu format or the like, and one incoming telephone number 14b is selected with a cursor key or the like. May be. In any case, a communication path can be more easily established between the calling telephone terminal 10 and any one of the plurality of receiving telephone terminals 30 only by performing a simple operation.

(A3) When the authentication code 14c is stored in the storage means 14 (see FIG. 1), the second calling means 16b sets the authentication code 14c to the calling number before calling with the incoming telephone number 14b as the calling number. (See FIG. 3; S17, S22). In this example, the authentication code 14c is called and then the called telephone number 14b is called. However, depending on the system of the specific relay station 20, the called telephone number 14b must be called before the authentication code 14c is called. In some cases. The communication path establishment device 16 is configured to call the authentication code 14c when receiving the authentication code information from the calling side telephone terminal 10 (S17), and to call the called telephone number 14b when receiving the incoming phone number information. (S22). Therefore, even when the authentication code 14c is requested from the specific relay station 20 or the receiving side telephone terminal 30, the communication path can be quickly established.

(A4) The communication path establishment device 16 is configured to be connectable to the caller telephone terminal 10 (see FIG. 1). Further, when the communication path establishment device 16 detects the connection with the calling side telephone terminal 10, the first calling means 16a makes a call using the specific station telephone number 14a as the calling number (see FIG. 2; S10, S11). Since the user only needs to connect to the calling side telephone terminal 10, the user can quickly connect the calling side telephone terminal 10 and the called side telephone terminal 30 via the specific relay station 20 without any trouble. Can establish a communication path.

(A5) The first calling means 16a is configured to regard the telephone number stored at a specific address (for example, address 000) in the storage means 14 as the specific station telephone number 14a and to make a call as a calling number (FIG. 2). See S4, S8, S9). In other words, the first calling means 16a calls the telephone number stored in the specific address using the specific station telephone number 14a as the calling number without requiring the input or selection of the specific station telephone number 14a. Since it is not necessary to select which telephone number is the specific station telephone number 14a, communication is quickly performed between the calling telephone terminal 10 and the receiving telephone terminal 30 via the specific relay station 20 without any trouble. A road can be established.

  The second embodiment is an example realized by providing a part of the function of the communication path establishment device 16 described in the first embodiment in the caller side telephone terminal 10. For the sake of simplicity of illustration and description, the second embodiment will be described with respect to differences from the first embodiment. Moreover, if it is the same as the element (function) used in Example 1, the same code | symbol is attached | subjected and description is abbreviate | omitted.

  First, a configuration example of the second embodiment is shown in a block diagram in FIG. Compared to the configuration example of the first embodiment shown in FIG. 1, the difference is that the calling telephone terminal 10 includes the first calling means 16a, the second calling means 16b, and the selecting means 16c. In realizing this configuration, the control program of the calling side telephone terminal 10 is changed, or the program is added to the storage unit 14 and stored so as to be operable by the calling side telephone terminal 10. Such a program corresponds to, for example, a Java (registered trademark) application program (hereinafter simply referred to as “Java (registered trademark)”) or the like, and may be stored in advance or stored by downloading from the Internet or the like. Also good.

  In the configuration described above, flow control for establishing a communication path between the originating side telephone terminal 10 and the terminating side telephone terminal 30 will be described with reference to FIG. When the user activates the designated Java (registered trademark), the following processing is realized.

  First, the processing is divided depending on whether or not the address of the storage means 14 for storing a telephone number or the like is fixed (S30). If at least one of the specific station telephone number 14a, the incoming telephone number 14b and the authentication code 14c is not fixed in S30 (NO), the user is requested to input an address. When an address is input, the process is divided depending on whether the data input by the user is an address (S31). If it is discriminated as an address in S31 (YES), data corresponding to the address (telephone number or authentication code, etc.) is acquired from the storage means 14 and stored in the work area of the storage means 14. On the other hand, if it is determined as a telephone number or the like in S31 (YES), the telephone number or the like is stored as it is in the work area of the storage means 14.

  Then, the specific station telephone number 14a stored in the work area of the storage means 14 is called as the calling number (S11). In the flow control after S11, a call is made with the incoming telephone number 14b and the authentication code 14c stored in the work area as the outgoing number (S18, S20), and between the communication path establishment device 16 and the outgoing side telephone terminal 10 Except that no communication is performed (S16, S17, S, S21, and S22 shown in FIG. 3). Therefore, just by executing Java (registered trademark), a communication path can be established between the originating side telephone terminal 10 and the terminating side telephone terminal 30 via the specific relay station 20 in the same manner as in the first embodiment. Therefore, the same effect as Example 1 is obtained.

  The third embodiment is an example in which some functions are left in the communication path establishment device 16 described in the first embodiment and other functions are provided in the calling side telephone terminal 10. For the sake of simplicity of illustration and description, the third embodiment will be described with respect to differences from the first embodiment. Moreover, if it is the same as the element (function) used in Example 1, the same code | symbol is attached | subjected and description is abbreviate | omitted.

  First, a configuration example of the third embodiment is shown in a block diagram in FIG. Compared to the configuration example of the first embodiment shown in FIG. 1, the following points are different. The first difference is that only the storage unit 16d is left in the communication path establishment device 16, and the first calling unit 16a, the second calling unit 16b, and the selection unit 16c are provided in the calling side telephone terminal 10. In realizing this configuration, the control program of the calling side telephone terminal 10 is changed in the same manner as in the second embodiment, or the program is added and stored in the storage unit 14 so as to be operable on the calling side telephone terminal 10. The second difference is that the specific station telephone number 14a is stored in the storage means 16d in advance.

  Flow control for establishing a communication path between the originating side telephone terminal 10 and the terminating side telephone terminal 30 in the configuration described above will be described with reference to FIGS. Between FIG. 7 and FIG. 3, the processing continues through connectors A, B, C, D, and E, respectively. FIG. 7 is a diagram for explaining flow control in place of FIG.

  The flow control shown in FIG. 7 is different in that the processes from S4 to S9 in the flow control of FIG. 2 are processed as follows. That is, the calling side telephone terminal 10 does not wait for an address input request from the communication path establishment device 16 and prompts the user to input, but waits for the user to input data such as an address or telephone number from the beginning. When the data is input, it is transmitted to the communication path establishment device 16 (S40). Whether or not data has been input is determined based on whether or not a predetermined key has been input. For example, the determination is made based on whether or not a designated character other than numerals is input such as “# 123 #”. If the user inputs “# 123 #”, it means that the incoming telephone number 14b is designated by the address “123”. If “# 09012345678 #” is input, it means that the incoming telephone number 14b is designated by the telephone number “09012345678”.

  On the other hand, the communication path establishment device 16 is also waiting for data to be transmitted from the calling side telephone terminal 10 (S41), and when receiving the data (YES), whether the data input by the user is an address or not. The process is divided (S42). Since the method for determining whether or not the address is the same as in the first embodiment, the description thereof is omitted here.

  If it is determined as an address in S42 (YES), the communication path establishment device 16 requests the calling side telephone terminal 10 for the contents stored in the address (S43), and the calling side telephone terminal 10 responds to this request. The contents stored at the designated address are returned to the communication path establishment device 16 (S44). However, since the specific station telephone number 14a is stored in advance in the storage means 16d, a request is made for the incoming telephone number 14b and the authentication code 14c in S43. Therefore, each of the incoming telephone number 14b and the authentication code 14c is specified by either the telephone number transmitted from the calling telephone terminal 10 in S40 or the telephone number answered from the calling telephone terminal 10 in S44. And stored in the storage means 16d. Since S10 and subsequent steps for requesting the calling side telephone terminal 10 to make a call using the specific station telephone number 14a stored in the storage unit 16d as the calling number are the same as those in the first embodiment described above, the description will be given here. Is omitted.

According to the third embodiment described above, the following effects can be obtained.
(C1) When the user operates a key provided in the calling side telephone terminal 10 and detects that the key operation is performed in a predetermined procedure such as “# 123 #” (“data shown in FIG. 7” The first calling means 16a makes a call using the specific station telephone number 14a as a calling number (see FIG. 7; S10, S11). Since the user only needs to perform key operations according to a predetermined procedure, it is possible to quickly establish a communication path between the calling side telephone terminal and the called side telephone terminal 30 via the specific relay station 20 without time and effort. Can do.

(C2) The specific station telephone number 14a is stored in the storage means 16d, and the incoming telephone number 14b and the authentication code 14c are stored in the storage means 14. The first calling means 16a makes a call using the specific station telephone number 14a stored in the storage means 16d as a calling number (see FIG. 7; S10, S11), and the second calling means 16b is stored in the storage means 14. The incoming telephone number 14b is called as a calling number (see FIG. 3; S22, S23). The incoming telephone number 14b only needs to be changed and stored in the storage means 14 of the caller telephone terminal 10. If the incoming telephone number 14b changes, the changed telephone number can be used easily and quickly without applying to the relay station as in the prior art. Therefore, it is possible to quickly establish a communication path to the receiving side telephone terminal 30 via the specific relay station 20 with the changed telephone number without any trouble (see FIG. 3; S27).

  In this example, the specific station telephone number 14a is stored in the storage means 16d, and the incoming telephone number 14b and the authentication code 14c are stored in the storage means 14, but may be stored in other combinations. For example, the incoming telephone number 14b and the authentication code 14c are stored in the storage means 16d, and the specific station telephone number 14a is stored in the storage means 14. One or more of the specific station telephone number 14a, the incoming telephone number 14b, and the authentication code 14c are stored in the storage unit 16d, and the other are stored in the storage unit 14. Even in this case, it is possible to quickly establish a communication path to the receiving side telephone terminal 30 via the specific relay station 20 with the telephone number after the change without taking time and effort. Others are the same as in the first embodiment, and therefore the same effects as those in the first embodiment can be obtained.
