FIG. 2 is a flowchart for explaining an example of the operation flow of the extension telephone system 1 shown in FIG. 3 shows that when a call is received by the radio telephone 31 accommodated in the extension telephone system 1 shown in FIG. 1, the radio telephone 31 and each fixed telephone such as each IP telephone 11 and each digital telephone 21 are connected. It is explanatory drawing for demonstrating the relative positional relationship between them.

  In the flowchart of FIG. 2, first, when an incoming call is received from an outside line or an extension line to any one of a plurality of IP telephones 11 or a digital telephone 21 or a radio telephone 31 accommodated in the extension telephone system 1 (steps). S1) The control unit 2 of the extension telephone system 1 determines whether or not the telephone with the extension number of the incoming call destination is a wireless telephone 31 such as a mobile phone or a PHS terminal (step S2).

  If the telephone of the extension number of the called party is not the wireless telephone 31 (in the case of “No” in step S2), the called telephone is placed on the desktop or the like of either the IP telephone 11 or the digital telephone 21 Since it is an installed high-function fixed telephone, the incoming fixed telephone, that is, the speaker of the IP telephone 11 or the digital telephone 21 so as to receive the incoming call directly to the fixed telephone, that is, the IP telephone 11 or the digital telephone 21. A ring tone or a ring melody is output from the speaker 24 and a call is made to the user of the fixed telephone.

  On the other hand, when the telephone of the extension number of the destination is the wireless telephone 31 (in the case of “Yes” in Step S2), the fixed telephone, that is, the IP telephone 11 or the digital telephone located closest to the wireless telephone 31 The telephone 21 is specified, and the process shifts to a process for making a call to the specified fixed telephone instead of the wireless telephone 31 and making a response. For example, when there is an incoming call to the wireless telephone 31 shown in the explanatory diagram of FIG. 3, the process proceeds to a process for making an incoming call to the seventh fixed telephone 41 g that is closest to the wireless telephone 31.

  Here, in the explanatory diagram shown in FIG. 3, the IP telephone set 11 or the digital telephone set 21 set on the table is shown as the nth fixed telephone (n = 1 to 8), and the first fixed telephone is shown. Eight fixed telephones, that is, a telephone 41a, a second fixed telephone 41b,..., An eighth fixed telephone 41h, are distributed on each desk. As shown in FIG. 3, the fixed telephone of the IP telephone 11 or the digital telephone 21 that is closest to the place where the user carrying the radio telephone 31 such as a mobile telephone or a PHS terminal that has received an incoming call is This corresponds to the seventh fixed telephone 41g.

  In step S2 in the flowchart of FIG. 2, when the incoming call is to the wireless telephone 31, the control unit 2 of the extension telephone system 1 first drives the IP telephone control unit 3 and the digital telephone control unit 4 to execute the extension telephone. Each fixed telephone accommodated in the system 1, that is, each IP telephone 11 and each digital telephone 21 (that is, the first fixed telephone 41a,..., The eighth fixed telephone 41h in FIG. The microphone 25 is turned on, and it is instructed to prepare to receive and input voice information from the radio telephone 31 designated as the destination (step S3).

  The control unit of each fixed telephone that has received the instruction from the extension telephone system 1, that is, the IP telephone control unit 12 of each IP telephone 11 and the digital telephone control unit 22 of each digital telephone 21 (that is, the first fixed telephone 41a of FIG. ..., each fixed telephone control unit of the eighth fixed telephone 41h) turns on the respective microphones, that is, the microphone 15 or the microphone 25, and the speaker 34 of the wireless telephone 31 designated as the destination is used as a ringing tone or ringing melody. Preparation for receiving the audio information to be output via each microphone, that is, the microphone 15 or the microphone 25 is performed.

  Next, the control unit 2 of the extension telephone system 1 drives the radio telephone control unit 5 to receive a ring tone having a predetermined ringing cycle in which the extension number is superimposed on the radio telephone 31 designated as the destination. Alternatively, it is instructed to output voice information including a ringing melody (step S4). The wireless telephone control unit 32 of the wireless telephone 31 that has received the instruction from the extension telephone system 1 drives the voice generation unit 33 and is composed of a ringing tone or ringing melody with a predetermined ringing cycle with the extension number superimposed. By generating sound information and outputting it from the speaker 34, the user carrying the wireless telephone 31 is notified of the incoming call.

  On the other hand, the control unit of each fixed telephone, that is, the IP telephone control unit 12 of each IP telephone 11 and the digital telephone control of each digital telephone 21 that are preparing to receive voice information from the radio telephone 31 designated as the destination. The units 22 (that is, the fixed telephone control units of the first fixed telephone 41a,..., The eighth fixed telephone 41h in FIG. 3) receive the voice information input from the respective microphones, and are wirelessly designated as the destinations. Whether the voice information is from the telephone 31 is determined by analyzing the extension number included in the received voice information (step S5).

  The control unit of each fixed telephone, that is, the IP telephone control unit 12 of each IP telephone 11 and the digital telephone control unit 22 of each digital telephone 21 (that is, the fixed telephones of the first fixed telephone 41a,. When the control unit determines that the received voice information is voice information from the wireless telephone 31 designated as the destination, the measurement result of the reception level (volume level) of the voice information is determined. The information on the wireless telephone 31 included in the voice information is added to the extension telephone system 1 with the extension number of the wireless telephone 31 included therein.

  Extension telephone system that receives the volume level and extension number transmitted from each fixed telephone, that is, each IP telephone 11 and each digital telephone 21 (that is, first fixed telephone 41a,..., Eighth fixed telephone 41h in FIG. 3). The control unit 2 of 1 stores the volume level and extension number received from each fixed telephone in the storage unit 6 (step S6).

  Thereafter, the control unit 2 of the extension telephone system 1 stores each fixed telephone, that is, each IP telephone 11 and each digital telephone 21 (that is, the first fixed telephone 41a,. ) Compare the volume levels sent from each. Further, the control unit 2 of the extension telephone system 1 determines each fixed telephone, that is, each IP telephone 11 and each digital telephone 21 (that is, the first fixed telephone 41a in FIG. The positional relationship between each of the eighth fixed telephones 41h) and the radio telephone 31 that has received the call is determined and notified to the user via the output unit 7.

  Further, the control unit 2 of the extension telephone system 1 transfers the fixed telephone, that is, the IP telephone 11 or the digital telephone 21 that has received the highest volume level of the voice information output from the incoming wireless telephone 31 to the wireless telephone 31. Is identified as the fixed telephone, that is, the IP telephone 11 or the digital telephone 21 (step S7). That is, in the explanatory diagram shown in FIG. 3, it is determined that the seventh fixed telephone 41g is a fixed telephone, that is, the IP telephone 11 or the digital telephone 21 that is present at the position closest to the wireless telephone 31 that has received the incoming call. .

  Thereafter, the control unit 2 of the extension telephone system 1 determines the fixed telephone, that is, the IP telephone 11 or the digital telephone 21 (the first telephone shown in FIG. 7 fixed telephone 41g) is instructed to perform an incoming call operation as a fixed telephone that can respond in place of radio telephone 31 that has received an incoming call.

  In other words, the IP telephone control unit 3 or the digital telephone control unit 4 is driven to give an instruction to the fixed telephone, that is, the IP telephone 11 or the digital telephone 21 (that is, the seventh fixed telephone 41g in FIG. 3). A ringing tone or ringing melody with a predetermined ringing cycle is output from the speaker 14 of the IP telephone 11 or the speaker 24 of the digital telephone 21 (that is, the speaker of the seventh fixed telephone 41g in FIG. 3) to call the user. . (Step S8). Note that the ring tone or ring melody output here is specific voice information (for example, there is an incoming call) that is set to indicate that the incoming call operation can be answered on behalf of the incoming wireless telephone 31. A ringing tone or ringing melody in which the extension number of the wireless telephone is superimposed may be used.

  By performing the operation as described above, the user of the wireless telephone 31 that has received an incoming call can use the fixed telephone, that is, the IP telephone 11 or the digital telephone 21 (that is, FIG. 3) installed at the position closest to the user's location. The seventh fixed telephone 41g) and can make a call with the other party using the high-functional telephone function provided in the fixed telephone.

  In the above embodiment, in step S4 of FIG. 2, a predetermined ringtone or ringing melody with an extension number superimposed thereon is used as voice information generated and output by the voice generation unit 33 of the incoming radio telephone 31. Although the case where it is used is shown, the present invention is not limited to this case, and it is possible for each fixed telephone such as each IP telephone 11 or each digital telephone 21 to identify which wireless telephone 31 is the voice information. If it is possible voice information, the extension number of the wireless telephone 31 that has received the call may not be superimposed.

  For example, for the ringing tone ringing and ringing melody output as voice information, each wireless telephone 31 is uniquely assigned in advance so that the ringing ringing ringing ringtone and ringing melody are different for each wireless telephone 31. From which wireless telephone 31 each fixed telephone such as each IP telephone 11 or each digital telephone 21 that has received the voice information depends on the ringing cycle of the ringing tone output from the wireless telephone 31 or the difference in the incoming melody. It may be possible to identify whether it is voice information.

  Further, in the above-described embodiment, in each of steps S5 and S6 in FIG. 2, each fixed telephone such as each IP telephone 11 or each digital telephone that has received a ring tone or a ring melody having a predetermined ringing period with extension numbers superimposed thereon. In the above description, the extension number superimposed on the ring tone or the incoming melody is analyzed to determine that it is the voice information from the designated radio telephone 31. However, the present invention is limited to this case. is not. For example, each fixed telephone does not perform analysis processing related to the received voice information, and the voice information input from the microphone of the fixed telephone, that is, the microphone 15 of the IP telephone 11 or the microphone 25 of the digital telephone 21, is used as an extension. It may be transmitted to the telephone system 1 and the extension number analysis processing may be performed by the control unit 2 of the extension telephone system 1.

  In the above-described embodiment, when a call is received at the wireless telephone 31 in step S3 of FIG. 2, each fixed telephone housed in the extension telephone system 1, that is, each IP telephone 11 and each digital telephone 21 ( That is, with respect to the first fixed telephone 41a,..., The eighth fixed telephone 41h in FIG. However, the present invention is not limited to such a case.

  For example, the microphone 15 or the microphone 25 of each fixed telephone, that is, each IP telephone 11 and each digital telephone 21, is always set to the ON state, and if necessary, for example, an instruction from the extension telephone system 1 as in step S3 If there is, there may be a transition to a state of monitoring the reception of voice information from the radio telephone 31 designated as the destination, or from the extension telephone system 1 in step S3. Without being instructed, it may be set to a state in which it is constantly monitored whether or not voice information is received from the radio telephone 31 designated as the destination.

  Further, in some cases, for all the fixed telephones accommodated in the extension telephone system 1 to prepare to receive and input voice information from the radio telephone 31 to all the fixed telephones in an idle state. It is not necessary to give an instruction from the extension telephone system 1. For example, the fixed telephone, that is, the IP telephone 11 or the digital telephone 21 whose microphone is set to ON is in the vicinity of the radio base station where the radio telephone 31 designated as the destination is registered, that is, a predetermined area of the radio base station. It is also possible to give an instruction only to a fixed telephone that exists and is available.

  Further, in the above-described embodiment, in step S7 in FIG. 2, as a fixed telephone that can receive an incoming call instead of the incoming radio telephone 31, the fixed telephone that is present at the nearest position of the radio telephone 31 is used. Although the case where the telephone, that is, the IP telephone 11 or the digital telephone 21 is specified has been described, the present invention is not limited to such a case. For example, all the fixed telephones, that is, the IP telephones 11 or the digital telephones 21 whose volume level of the voice information received from the incoming radio telephone 31 is equal to or higher than a predetermined level threshold are used for the incoming radio telephone 31. Instead of this, it is possible to specify a fixed telephone that can receive a call and output a ringtone or ringtone.

  That is, in the explanatory diagram of FIG. 3, the range in which the voice information from the incoming radio telephone 31 can be received at the volume level equal to or higher than the level threshold is within the range of the incoming notification area 51 indicated by the outermost circle, for example. If not, not only the seventh fixed telephone 41g located in the shortest position from the wireless telephone 31 but also the third fixed telephone 41c and the sixth fixed telephone 41f located in the incoming call notification area 51 Even if the ringtone or ringtone is output. As a result, the user of the radio telephone 31 that has received an incoming call can connect any fixed telephone to any of the third fixed telephone 41c, the sixth fixed telephone 41f, and the seventh fixed telephone 41g to which a ring tone or ringing melody has been output. Can be used to respond.

(Explanation of effect of embodiment)
As described in detail above, the following effects are obtained in the embodiment of the present invention.

  The first effect is that, when an incoming call is received by a mobile telephone 31 such as a mobile phone or a PHS terminal accommodated in the extension telephone system 1, an IP telephone 11 or a digital telephone installed in the vicinity of the wireless telephone 31 Even a fixed telephone such as 21 can use advanced functions of the fixed telephone in response to the incoming call instead of the wireless telephone 31. The reason for this is that each of the fixed telephones such as the IP telephone 11 and the digital telephone 21 located in the vicinity of the wireless telephone 31 receives the voice information output as a ring tone or ringing melody from the incoming wireless telephone 31. Thus, each of them notifies the extension telephone system 1 of the volume level of the received voice information, so that the extension telephone system 1 can specify a fixed telephone installed in the vicinity of the wireless telephone 31. This is because the incoming call operation can be performed on the specified fixed telephone.

  The second effect is that a fixed telephone such as the IP telephone 11 or the digital telephone 21 installed in the vicinity of the radio telephone 31 that has received an incoming call can be reliably identified. The reason is that as voice information output from the wireless telephone 31 that has received an incoming call, a ringtone or ringing melody in which the extension number of the wireless telephone 31 is superimposed, or a ringing tone with a ringing period assigned to the wireless telephone 31 in advance. Alternatively, since the incoming melody is used, each fixed telephone or extension telephone system 1 that receives the voice information can reliably determine that the voice information is output from the radio telephone 31 that has received the incoming call. It is.

  The third effect is that the user of the wireless telephone 31 that has received an incoming call can select a fixed telephone that is most easily used from one or more fixed telephones and perform a response operation. The reason is not limited to the fixed telephone set installed at the position closest to the radio telephone 31 that received the incoming call, but all the volume levels of the voice information received from the radio telephone 31 are equal to or higher than a predetermined level threshold value. This is because it is also possible to output a ring tone or ring melody to a fixed telephone and call it.

  The configuration of the preferred embodiment of the present invention has been described above. However, it should be noted that such embodiments are merely examples of the present invention and do not limit the present invention in any way. Those skilled in the art will readily understand that various modifications and changes can be made according to a specific application without departing from the gist of the present invention.
