[0052]
FIG. 2 is a flowchart showing the operation of the private communication device 1 of FIG. In this figure, it is assumed that the mobile communication terminal 6a in FIG. 1 calls another communication terminal (one of the mobile communication terminal 6, the fixed extension telephone terminal 8, and the fixed telephone terminal 9 in FIG. 1). Take an example.
[0053]
Further, it is assumed that the position information is generated and stored by the wide area position detecting unit 22 and the narrow area position detecting unit 31 as appropriate, and the description is omitted.
[0054]
When the mobile communication terminal 6a, which is the calling terminal, transmits a call signal (call) (S1), the receiving unit 21a (FIG. 1) receives the signal (S2), and the location information collecting unit 23a transmits the signal to the mobile communication terminal 6a. To collect local location information.
[0055]
The determination executing unit 23b (FIG. 1) determines whether the calling terminal is located in the company A 3 (FIG. 1) based on the collected narrow area position information (S4). In the present embodiment, if the caller terminal is located in company A 3, it is determined that the call is for company communication, and if it is not located in company A, it is used for private communication (normal use). It is determined that there is.
[0056]
When the determination executing unit 23b determines that the caller terminal is not located in the company A 3 (S4: No), a call signal is transmitted to the callee terminal (the other communication terminal described above) (S14). .
[0057]
On the other hand, when it is determined that the calling terminal is located in company A 3 (S4: Yes), the wide area position information of the mobile communication terminal 6a is collected by the position information collecting unit 23a (S5), and the determination is executed. The unit 23b checks again whether the mobile communication terminal 6a is really located in the company A 3 (S6).
[0058]
For example, if the ID tag 7a comes off the mobile communication terminal 6a and is left inside the company A 3 and the mobile communication terminal 6a moves out of the company A 3 and performs private communication there, There is a possibility that an erroneous determination is made that the communication is for communication. The above S6 is executed to prevent such a situation.
[0059]
As described above, the wide area position information is not generated by receiving a position signal transmitted from the ID tag 7a attached to the mobile communication terminal 6a, but indicates the position of the mobile communication terminal 6a itself. Since it is generated by the detection, it detects a situation in which the mobile communication terminal 6a is located outside the company A 3 even though the ID tag 7a is located inside the company A 3. Therefore, the erroneous determination described above can be prevented.
[0060]
In S6, if the mobile communication terminal 6a itself is not located in the company A 3, it is determined that the mobile communication terminal 6a is not for company use (S6: No), and an announcement indicating that fact is sent to the mobile communication terminal 6a. (S8b).
[0061]
On the other hand, in step S6, when both the mobile communication terminal 6a and the ID tag 7a are located in the company A 3, if it is determined that the mobile communication terminal 6a is really for the company (S6: Yes), the call is called by the determination execution unit 23b. The called terminal number information included in the signal is extracted (S7), and it is confirmed whether the called terminal number is a sub number (S8a).
[0062]
When the number of the called terminal is a sub-number (S8a: Yes), since this called terminal is a mobile communication terminal (8b in FIG. 1), narrow-area position information relating to this is collected (S9a), and It is determined whether the destination terminal is located in company A 3 (S10a).
[0063]
If the called terminal is not located in company A 3 (S10a: No), an announcement indicating that is sent to mobile communication terminal 6a (S11b).
[0064]
On the other hand, if the called terminal is located in company A 3 (S10a: Yes), the wide area position information of the called terminal is collected (S11a), and whether the called terminal is really located in company A 3 Is determined (S12).
[0065]
If the called terminal is not located in company A 3 (S12: No), an announcement indicating this is sent to mobile communication terminal 6a (S13b).
[0066]
On the other hand, when the called terminal is located in company A 3 (S12: Yes), the sub-number is converted to the corresponding main number by the number conversion unit 24 (FIG. 1) (S13a) and converted. A call signal including the main number is transmitted to the called terminal by the transmitting unit 21b (FIG. 1) (S14), and the called terminal receives the signal. If there is a response, the call signal is transmitted between the mobile communication terminal 6a and the called terminal. The communication is established (S15), and charging is performed by the charging unit 25 (FIG. 1) (S16).
[0067]
It should be noted that the above-described S11a and S12 may not be executed. In this case, if the result of S10a is Yes, S13a is immediately executed.
[0068]
In S8a, if the number of the calling terminal is not the sub number but the main number of the mobile communication terminal 6b in FIG. 1 (S8a: No), the called terminal exists within the area of the base station 5. Is confirmed (S10b), if it is within the service area (S10b: Yes), S14 is executed, and if it is not within the service area (S10b: No), an announcement to that effect is sent to the mobile communication terminal 6a. (S11c).
[0069]
In S8a, if the called terminal is a fixed extension telephone terminal, S9b and S10b are not executed, and S14 is immediately executed.
[0070]

This point is also as described above.
[0072]
Further, in S8a (corresponding to S8a in FIG. 2), the determination unit 23 not only makes a “Yes” or “No” determination, but also based on [C] the called number information, “<1> the number of the called terminal "<2> The number of the called terminal is not a sub number", and "<3> The number of the called terminal is not a sub number but a number of a fixed extension telephone terminal (8 in FIG. 1). Any of the following is determined: "Yes" or "<4> The number of the called terminal is not the sub-number but the number of the fixed telephone terminal (9 in FIG. 1)."
[0073]
Further, in S9a (corresponding to S9a in FIG. 2), the determination unit 23 determines that “<1> the called terminal is in company A” or “<2>” on the basis of the [D] narrow-area position information of the called terminal. It is determined that the called terminal is not in company A. " This point is also as described above.
[0074]
Further, in S11a (corresponding to S11a in FIG. 2), the determination unit 23 determines whether “<1> the called terminal is surely in the A company” or “<2” based on the [E] wide-area position information of the called terminal. > The called terminal is not in A company "is determined. This point is also as described above.
[0075]
According to the above determination contents, the states of the communication terminals including the call destination terminal and the call source terminal are classified into eight types of patterns. FIG. 4 shows this state pattern.
