<P>PROBLEM TO BE SOLVED: To make it possible to have substitutive speech communication by substitutively answering an incoming call to a mobile phone, placed on a desk etc., where the owner is absent, without operating the mobile phone. <P>SOLUTION: The owner of the mobile phone previously registers substitutive answering permission conditions including a telephone number of a substitutively answering terminal. When the owner of the mobile phone is absent, a person who notices an incoming call to the mobile phone left alone calls the mobile phone of the absentee which is ringing by using his or her mobile phone or a fixed telephone set having been registered as the substitutive answering terminal, thereby performing substitutive speech communication. The substitutive answering is performed by suitably judging the position of the mobile phone of the absentee, the position of the substitutive answering terminal, and the time of the substitutive answering. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention relates to an alternative response system and an alternative response method, and in particular, when a mobile phone placed on a desk or the like receives an incoming call and the mobile phone holder is absent, the incoming call can be received without operating the mobile phone. The present invention relates to an alternative response system, an exchange, and an alternative response method that enable an alternative call by making an alternative response.

  Fixed telephones installed in offices and homes have traditionally been recognized as a common property, and even if there is an incoming call to a fixed telephone on an absentee's desk, There was no resistance to other people answering the incoming call. However, mobile phones are now communication devices owned by individuals, and almost one person owns one. Therefore, even if there is an incoming call on a mobile phone placed on the desk of an absentee or a mobile phone in the absentee's cage and a ringtone is emitted, a person nearby is There is often a sense of resistance in responding by operating the telephone. Even when people are in the same office or family, when a call arrives on a mobile phone owned by an absentee, it is common practice to simply wait for the ringtone to stop. It is. Also, the owner of a mobile phone often does not want others to operate the mobile phone that he owns.

  However, even in such a situation, as long as it is a communication device, a call that arrives at a mobile phone may be an important communication for the absentee. In such a case, we would like to avoid a situation in which there was a disadvantage for the absentees later because nobody responded to the substitute even though there was a related party nearby. In other words, in a specific environment such as an office or home, when a call is received by a mobile phone owned by an absentee, it is difficult to say that the response is simply waiting for the ringtone to stop ringing. .

  Japanese Laid-Open Patent Application No. 5-219217 (Patent Document 1) discloses a technique related to a service that makes a proxy response to an incoming call when there is no call. Japanese Laid-Open Patent Publication No. 5-327900 (Patent Document 2) discloses a technique related to a telephone exchange device having a function of transferring a call received by an absentee from another extension telephone to another destination.

  In the proxy response service disclosed in Patent Document 1, a call received on a telephone that is registering a proxy response is received by a management terminal, and a proxy responder of the management terminal calls a management message registered in the management message registration device It is a proxy response to the person. If the management terminal does not respond, the management message registered in the management message registration device is converted into voice by the voice information conversion device and notified to the caller.

The telephone exchange device disclosed in Patent Document 2 does not respond to an extension telephone that is ringing by performing a forwarding destination special number process from another extension telephone when an incoming call is received by an unattended extension telephone. This is a telephone exchange device that can transfer a call to an extension telephone to which an absentee goes.

JP-A-5-219217 JP-A-5-327900

  The techniques disclosed in Patent Document 1 and Patent Document 2 are common in terms of performing processing for a case where there is no person to answer an incoming call. However, the proxy response service disclosed in Patent Document 1 only transmits the management message registered in advance by the absentee to the caller unilaterally. Therefore, the communication content that the caller wanted to convey to the absentee remains untransmitted to the absentee. Further, the telephone exchange device disclosed in Patent Document 2 cannot perform such transfer processing unless the person who performs the transfer special number processing using another extension telephone knows the destination of the absentee. Therefore, the communication content that the caller wanted to convey to the absentee is still not transmitted to the absentee.

  An object of the present invention is that when a call arrives at a mobile phone owned by the absentee, a person related to the absentee responds to the incoming call as an alternative without operating the mobile phone. An alternative response system, an exchange, and an alternative response method capable of communicating with

  In order to achieve the above object, the alternative response system, the exchange and the alternative response method according to the present invention register the telephone numbers of the fixed telephones or mobile telephones of the parties designated in advance by the owner of the mobile telephone, When a call arrives at a mobile phone owned by an absentee, the call is received from the registered phone by specifying the phone number of the mobile phone that is receiving the call. It has a function that makes it possible to communicate with the caller by performing an alternative response without operating the mobile phone at all.

  According to the alternative response system, the exchange, and the alternative response method according to the present invention, a person who notices the ring tone of the absentee's mobile phone can directly operate his / her own mobile phone or the user without operating the absentee's mobile phone directly. An alternative call can be made by making a call to a mobile phone that is ringing using a fixed telephone. Therefore, it becomes possible to encourage a more active alternative call to a person who feels resistance to operating another person's mobile phone.

  Therefore, it is possible to avoid a situation in which there is a disadvantage to the absentees later because nobody responds to the substitutes even though there are concerned parties. It is possible to improve an opportunity for an alternative call to the telephone.

  Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a block diagram conceptually showing an outline of an embodiment of the present invention.

  In the embodiment of the present invention, as shown in FIG. 1, the caller terminal 100, the absentee terminal 300 that receives a call from the caller terminal 100, recognizes the ringing sound of the absentee terminal 300, and performs an alternative response. The switch 200 includes an alternative response terminal 400 and an exchange 200 that executes and controls an alternative response according to the present invention. The exchange 200 includes an alternative response management database 210 described later. Further, S1 to S6 in FIG. 1 indicate the execution order of the alternative response method according to the present invention.

  The outline of the embodiment of the present invention is as follows.

  The owner of the mobile phone that can be the absentee terminal 300 registers in advance the telephone number of the alternative response terminal 400, which is a mobile phone or a fixed telephone that allows an alternative call depending on the place or time zone, in the alternative response management database 210 of the exchange 200 (S1).

  In such a state, the caller terminal 100 makes a telephone call (S2), and the telephone call is received by the mobile phone (the unattended terminal 300) left without the owner, and the unattended terminal 300 A ring tone sounds at (S3). A person who has recognized the ringing sound of the absentee terminal 300 makes a call from the previously registered alternative response terminal 400 using the telephone number of the absentee terminal 300 that is ringing for an alternative response (S4).

  When the exchange 200 identifies the outgoing call to the absentee terminal 300 by the alternative response, the exchange 200 refers to the alternative response management database 210 and confirms whether the alternative response is an allowable telephone number, location, and time zone. To do. When the alternative response is permitted, the telephone call from the caller terminal 100 that is receiving the call to the absentee terminal 300 is changed to the alternative response terminal 400 (S5).

  Through the above operation, the caller terminal 100 that has made a call to the absentee terminal 300 is connected to the alternative response terminal 400 and can make a call with the alternative response terminal 400 (S6).

  In this way, in the present invention, a direct alternative call with the caller is realized without operating the mobile phone that is the absentee terminal 300 at all.

  An embodiment of the present invention will be described in detail with reference to FIGS.

  FIG. 2 is a data table showing an example of alternative response management data set in the alternative response management database 210. The alternative response management data is set by grouping alternative response conditions in units of absentee terminal telephone numbers 211.

  The alternative response condition includes an alternative response terminal telephone number 212 in which a telephone number of a mobile phone or a fixed telephone that can be an alternative response terminal 400 that allows an alternative response is set, location designation information 213 that specifies a place where the alternative response can be made, and an alternative response It includes time designation information 214 that designates an allowable time zone. A condition in which the owner of a mobile phone wants an alternative response to a call that has arrived on the mobile phone while the mobile phone owner is left unattended on a desk or in a bag Is set in the alternative response management database 210 by performing a setting registration process described later.

  A time zone in which the mobile phone owner who has location-specific information from the viewpoint of permitting an alternative response only in a specific environment such as a business office or home where he / she is working and who can become an absentee terminal 300 is active at that location Time designation information from the viewpoint of permitting an alternative response only to.

  For example, assuming a mobile phone owner who is active at office A from 9:00 to 17:00 and sometimes at office B from 12:00 to 17:00, the telephone number (ABB- MM-XXXX) or a mobile phone number (ACB-NM-XXXX) owned by a colleague of the office A is set as the alternative response terminal telephone number 212, and the location designation information 213 corresponds to the office A The place and time designation information 214 is set to 9 o'clock to 17 o'clock, which is the time zone in which the user is active. Furthermore, the telephone number of the fixed telephone at the office B (BAC-LL-XXXX) and the telephone number of the mobile telephone owned by a colleague at the office B (CBB-ML-XXXX) are set as the alternative response terminal telephone number 212. The location designation information 213 is set to a location corresponding to the office B, and the time designation information 214 is set to 12:00 to 17:00, which is the time zone in which the site is active. At home C, the telephone number (CAA-NL-XXXX) of the home fixed telephone is set as the alternative response terminal telephone number 212, and the location designation information 213 includes the location corresponding to the home C and the time designation information 214. Sets the all-day time zone from midnight to 24:00.

  In such a case, the owner of this mobile phone leaves his / her mobile phone on the desk or in the bag at the office A, and from 9:00 to 17:00 In response to a call arriving at the mobile phone while it is absent, a fixed phone (telephone number ABB-MM-XXXX) at office A or a mobile telephone (telephone number) owned by a colleague at office A An alternative response is possible from (ACB-NM-XXXX). However, even if a telephone having another telephone number is a telephone capable of an alternative response at the office B or a telephone capable of an alternative response at the home C, the alternative response is not allowed.

  Similarly, in response to a call that has arrived at the cellular phone while the absentee terminal 300 left at the office B is absent during the time period from 12:00 to 17:00, The telephone number BAC-LL-XXXX) or a mobile phone owned by a colleague at the office B (phone number CBB-ML-XXXX) can be used as an alternative response. Even if the telephone is capable of an alternative response at the office A or the telephone capable of an alternative response at home C, the alternative response is not allowed.

  Of course, when the mobile phone is left at home (home C), an alternative response is possible from the fixed phone (phone number CAA-NL-XXXX) at home (home C). Alternative responses by telephones with numbers are not allowed.

  That is, according to the present invention, in principle, an alternative response is allowed under the condition that the alternative response terminal telephone number 212, the location designation information 213, and the time designation information 214 all match, corresponding to the place where the absentee terminal 300 exists. .

  Next, an alternative response management data setting registration process set in the alternative response management database 210 will be described with reference to FIG.

  FIG. 3 is a flowchart showing the setting registration process of the alternative response management data executed in the exchange 200.

  The owner of the mobile phone who desires an alternative response according to the present invention sets and registers the alternative response condition with the telephone number of the mobile phone owned by himself / herself as the absentee terminal telephone number 211.

  First, a setting registration process is requested to the exchange 200 by a registration special number for setting registration of alternative response conditions from a mobile phone owned by the user.

  The exchange 200 that has received the registration special number performs setting and registration processing of alternative response conditions according to the flow shown in FIG. In this setting registration process, an operation guidance by a voice response device (not shown) of the exchange 200 is sent to a registrant, information by an interactive response from the registrant is acquired, and the registration information is sequentially accumulated. It may be set in the alternative response management database 210.

  When the registration special number is received (S301), the exchange 200 acquires information on the registrant (S302). The information on the registrant is the phone number of the registrant's mobile phone and the location registration information of the mobile phone included in the signal at the time of transmitting the registration special number as sender information. As the location registration information, the location registration information of the mobile phone managed in the mobile communication network may be acquired using the sender information as key information. Accordingly, the location registration information is information for each base station covering the communication area of the mobile phone.

  When the acquisition of the registrant information is completed, the exchange 200 requests the registrant to input an alternative response terminal telephone number, and acquires the alternative response terminal telephone number input by the registrant (S303).

  Subsequently, the exchange 200 inquires the registrant about whether or not the time is specified (S304). When no time is specified (S304: NO), the all-day condition of 0:00 to 24:00 is registered in the time specification information 214 (S305). If there is a time designation (S304: YES), the time information designated by the registrant is acquired (S307).

  Thus, the alternative response condition for one alternative response terminal is acquired. When the alternative response terminal is subsequently registered (S307: NO), the processing from S303 is repeated.

  Upon receiving notification that the registration of the alternative response condition by the registrant has been completed (S307: YES), the exchange 200 uses the information obtained by the above operation as an alternative response condition and is shown in FIG. 2 in the alternative response management database 210. In this manner, the setting is registered (S308), and the process is terminated. Note that the subscriber data (not shown) corresponding to the mobile phone that has been registered in the alternative response management database 210 also indicates that the subscriber is a subscriber who has performed the alternative response setting registration. Is set.

  Through the above operation, the substitute response management database 210 obtains the phone number of the registrant's mobile phone as the absentee phone number 211 and the substitute response phone number entered by the registrant as the substitute response phone number 212. The registered location registration information is set in the location designation information 213, and the time information specified by the registrant or when there is no time designation is set in the time designation information 214.

  With reference to FIG. 4, an explanation will be given on the operation of the alternative response performed by the alternative response terminal 400 for a call that has arrived at the mobile phone in which the alternative response management data is set in the alternative response management database 210 as described above.

  FIG. 4 is a sequence diagram for explaining the operation of the alternative response method according to the present invention.

  In FIG. 4, when there is an incoming call from the caller terminal 100 to the absentee terminal 300 (S 401), a ringtone sounds at the absentee terminal 300. Related parties that have recognized the ringing sound of the absentee terminal 300 make a call specifying the telephone number of the absentee terminal 300 from the alternative response terminal 400 in order to execute the alternative response using the alternative response terminal 400 To do. At this time, an alternate response special number for identifying the alternate response call is also designated (S402).

  Upon receiving the substitute response special number and the absentee terminal telephone number, the exchange 200 executes substitute response processing (S403) with reference to the substitute response management data corresponding to the absentee terminal 300 set in the substitute response management database 210. To do.

  As a result of the alternative response processing, when the alternative response by the alternative response terminal 400 matches the allowable condition, the exchange 200 connects the call received from the caller terminal 100 to the absentee terminal 300 to the alternative response terminal 400. Change (S404). As a result, the caller terminal 100 and the alternative response terminal 400 are connected, and communication can be performed between the parties who have made an alternative response from the alternative response terminal 400 and the caller (S405).

  Next, the configuration of the alternative response system according to the present invention and the details of the alternative response operation will be described with reference to FIGS.

  FIG. 5 is a block diagram showing a configuration of an alternative response system according to the present invention.

  The same components as those described with reference to FIG. 1 are given the same reference numerals. That is, the caller terminal 100, the absentee terminal 300 that has received a call from the caller terminal 100, the substitute response terminal 400 that recognizes the ringing sound of the absentee terminal 300 and performs a substitute response, and the substitute response according to the present invention. The exchange 200 for execution control and the alternative response management database 210 are as described in FIG. FIG. 5 shows the positional relationship of the above-described constituent devices and the configuration of the exchange 200 in more detail.

  FIG. 5 shows that an incoming call to the mobile phone (absent terminal 300) of the caller terminal 100 arrives at the exchange 200 via the communication network 700, and the exchange 200 performs a base operation based on the location registration information of the absentee terminal 300. An incoming paging is performed from the station 500, and the absentee terminal 300 shows a state where a ringing tone is ringing in response to the incoming paging. The caller terminal 100 may be a mobile phone or a fixed phone. Accordingly, the communication network 700 is a mobile communication network if the caller terminal 100 is a mobile phone, and is a PSTN (Public Switched Telephone Network) if it is a fixed phone.

  On the other hand, the alternative response terminal 400 that makes an alternative response to the absentee terminal 300 may be a mobile phone or a fixed phone. Therefore, in FIG. 5, two types of terminal forms are shown.

  The exchange 200 for executing and controlling an alternative response according to the present invention has the following configuration apparatus as the configuration according to the present invention, in addition to the above-described alternative response management database 210.

  First, the network interface unit 260, which is a network side interface that forms a communication path, the base station interface unit 270, which is an interface on the base station side, the call control unit 240 that controls overall call control, and the alternative response control according to the present invention An alternative response control unit 230 and a location management database 220, and a message transmission unit 250 that transmits a message to the caller terminal 100 or the alternative response terminal 400 at the time of an alternative response. The location management database 220 is a database for specifying location information of the alternative response terminal 400 that has made an alternative response, and will be described later. In FIG. 5, the alternative response management database 210 and the location management database 220 are shown as DB1 and DB2, respectively.

  Note that the call control unit 240 and the alternative response control unit 230 are configured by software processing in which a CPU (Central Processing Unit) (not shown) reads and executes a call processing program and an alternative response program that are also written in a memory (not shown). Including the realized form.

  FIG. 6 is a flowchart showing an alternative response process executed in the exchange 200.

  First, an incoming call from the caller terminal 100 to the absentee terminal 300 arrives at the exchange 200 via the communication network 700, and the exchange 200 receives incoming paging from the base station 500 based on the location registration information of the absentee terminal 300. The absentee terminal 300 is ringing in response to the incoming call paging.

  In such a state, the related parties who have recognized the ringtone ringing of the absentee terminal 300 can call the absentee terminal 300 to which the alternative response special number is added in order to execute the alternative response using the alternative response terminal 400. An alternative answering call is made from the alternative answering terminal 400 with the number specified as the destination telephone number. That is, a call setting request message of an alternative response call in which the telephone number of the alternative response terminal 400 is set as the caller number and the telephone number of the absentee terminal 300 with the alternative response special number added as the called party number is transmitted to the exchange 200. The

  When the alternative response terminal 400 is a mobile phone, the alternative response call is received from the vicinity of the absentee terminal 300 where the ringing tone is ringing, so that this alternative response call arrives at the exchange 200 via the base station 500. On the other hand, when the alternative response terminal 400 is a fixed telephone, this alternative response call is received by the exchange 200 via the PSTN 600. Accordingly, the exchange 200 sends a call setting request message for an alternative response call via the base station interface unit 270 if the alternative response terminal 400 is a mobile phone, or a network if the alternative response terminal 400 is a fixed phone. Received via the interface unit 260 (S501).

  The exchange 200 that has received the call setting request message for the alternative response call identifies the alternative response special number and determines whether or not the alternative response process can be executed in the call control unit 240 (S502). That is, it is determined on the basis of subscriber data (not shown) whether the designated absentee terminal 300 is performing substitution response setting registration and whether the absentee terminal 300 is still busy at the present time.

  If at this stage, the mobile phone corresponding to the absentee terminal 300 has not set and registered the alternative response, or the caller terminal 100 has already disconnected the call, the alternative response execution disapproval determination If (S503: NO) is made, the alternative response terminal 400 is connected to the message transmitting device 250, and a message indicating that the alternative response is not permitted is sent (S508). When the alternative response terminal 400 is a mobile phone, the message is transmitted from the message transmitting device 250 connected to the base station interface unit 270 side. When the alternative response terminal 400 is a fixed phone, the message is connected to the network interface unit 260 side. A message indicating that the alternative response is not permitted is transmitted from the transmission device 250.

  If the alternative response execution permission determination is made in the above determination (S503: YES), the alternative response control unit 230 executes the alternative response control. At this time, the call control unit 240 notifies the alternative response control unit 230 of the telephone number of the absentee terminal 300 and the telephone number of the alternative response terminal 400 included in the call setting request message of the alternative response call.

  The alternative response control unit 230 refers to the alternative response management database 210 and the location management database 220 based on the notification information and performs a process of determining whether or not an alternative response can be executed (S504). That is, in response to the location where the absentee terminal 300 exists, it is determined whether or not all of the alternative response terminal telephone number 212, the location designation information 213, and the time designation information 214 shown in FIG. Allow alternative responses when conditions are met.

  Hereinafter, this determination process will be described with reference to FIG.

  First, the alternative response control unit 230 identifies the alternative response management data set corresponding to the absentee terminal 300 in the alternative response management database 210 based on the telephone number of the absentee terminal 300 in the notification information (S5041). . That is, the substitute response management database 210 is searched using the telephone number of the absentee terminal 300 of the notification information as key information, and the absentee terminal telephone number 211 that matches the telephone number of the absentee terminal 300 of the notification information is specified. Then, the alternative response management data set corresponding to the absentee terminal telephone number 211 is referred to.

  Subsequently, the alternative response control unit 230 determines whether or not the telephone number of the alternative response terminal 400 of the notification information is set in the telephone number registered in the alternative response terminal telephone number 212 of the alternative response management data ( S5042). If the telephone number of the alternative response terminal 400 that has sent the alternative response call is not set, a flag of disapproval is set for the alternative response terminal 400 as not allowing the alternative response (S5046). If the telephone number of the alternative response terminal 400 that has sent the alternative response call is set, it is determined whether the location designation condition 213 and the time designation condition 214 match or do not match (S5043).

  First, for the time designation condition 214, the current time is identified by a timer device (not shown), and the match / mismatch of the time designation condition 214 is determined by comparing the condition set in the time designation condition 214 with the current time. . That is, if the time is not set in the time specification condition 214, an alternative response is not allowed. If the current time is the time set in the time specification condition 214, then it is determined whether or not the location specification condition 213 matches.

  First, the alternative response control unit 230 determines whether or not the absentee terminal 300 exists in a place set in the place designation condition 213.

  As described in S <b> 302 of FIG. 3, information based on the location information that the absentee terminal 300 has registered for the alternative response setting is set in the location designation condition 213. The current location information of the absentee terminal 300 can be obtained by searching the location management database 220 using the telephone number of the absentee terminal 300 in the notification information as key information. In other words, the location management database 220 always manages location information based on location registration operations performed by the mobile phone, so by referring to this location management database 220, the absentee terminal can be located at a place where an alternative response is desired. It is determined whether 300 is present.

  The location information of the absentee terminal 300 uses the base station information of the base station 500 that returns a response to the incoming paging performed when the incoming call from the originator terminal 100 is received by the absentee terminal 300. Is also possible.

  If the current position of the absentee terminal 300 is a place that is not set in the place designation condition 213, the alternative response is not permitted.

  When it is confirmed that the current position of the absentee terminal 300 is the place set in the location specification condition 213, the alternative response control unit 230 exists in the place where the alternative response terminal 400 is set in the location specification condition 213. It is determined whether or not to do. In this case, the determination method differs depending on whether the alternative response terminal 400 is a mobile phone or a fixed phone.

  When the alternative response terminal 400 is a mobile phone, the location information of the alternative response terminal 400 can be obtained by searching the location management database 220 using the telephone number of the alternative response terminal 400 of the notification information as key information. It is also possible to use the base station information of the base station 500 when the alternative response call is accepted.

  If the current position of the alternative response terminal 400, which is a mobile phone, is a location that is not set in the location designation condition 213, the alternative response is not permitted.

  On the other hand, when the alternative response terminal 400 is a fixed telephone, the location information of the alternative response terminal 400 is obtained as follows by searching the location management database 220 using the telephone number of the alternative response terminal 400 of the notification information as key information. Can be obtained.

  The location management database 220 according to the present invention not only manages the location information of the mobile phone, but also based on the phone number system assigned in the PSTN of the fixed phone, which base station has the phone number in the mobile communication network Correspondence information indicating whether or not the communication area is covered. That is, it is possible to specify the installation location of the PSTN switching office that accommodates the fixed telephone by the area code and the local area code of the fixed telephone number system. Then, the correspondence relationship between the specified installation position of the exchange station and the installation position of the base station in the mobile communication network is grasped in advance. Furthermore, based on the subscriber number of the telephone number system of the fixed telephone, detailed information about the subscriber's home located in the east, west, north, or south direction from the installation location of the accommodated PSTN exchange is provided. Also good.

  As described above, even if the alternative response terminal 400 is a fixed telephone, the installation location of the fixed telephone can be identified in association with the base station of the mobile communication network using the telephone number as key information. Then, it is determined whether or not the installation location of the fixed telephone thus obtained is a location set in the location designation condition 213.

  If the current location of the alternative response terminal 400 that is a fixed telephone is a location that is not set in the location designation condition 213, the alternative response is not permitted.

  If both the time designation condition and the location designation condition described above match (S5044: YES), the alternative response is allowed, so the result of matching / mismatch determination processing of the location designation condition 213 and the time designation condition 214 Then, a permission flag is set (S5045). Further, if the condition is such that the alternative response is not permitted (S5044: NO), a non-permission flag is set (S5046).

  Thus, the alternative response control by the alternative response control unit 230 is completed, and the control result is notified to the call control unit 240 as a permission / non-permission flag. The call control unit 240 executes subsequent connection control according to the permission / non-permission flag notified from the alternative response control unit 230.

  When the permission flag is notified (S505: YES), the caller terminal 100 connected to the absentee terminal 300 and receiving the call signal is switched to the message transmitting device 250 prepared on the network interface side. (S506). After sending a message notifying that an alternative response is to be sent from the message transmitting device 250, the alternative response terminal 400 is connected to the caller terminal 100 and the process is terminated (S507). As a result, the alternative responder who has transmitted the alternative response call from the alternative response terminal 400 can make a call with the caller of the transmission terminal 100.

  On the other hand, when the non-permission flag is notified (S505: NO), the alternative response terminal 400 is connected to the message transmitting device 250, and a message indicating that the alternative response is not permitted is transmitted (S508). When the alternative response terminal 400 is a mobile phone, the message is transmitted from the message transmitting device 250 connected to the base station interface unit 270 side. When the alternative response terminal 400 is a fixed phone, the message is connected to the network interface unit 260 side. A message indicating that the alternative response is not permitted is transmitted from the transmission device 250.

  As described above, the alternative response system, the exchange, and the alternative response method according to the present invention do not require a special device on the user side, such as an unattended mobile phone or an alternative response terminal, and replace the place, time, terminal, etc. The alternative response environment can be flexibly set by appropriately grouping the response permission conditions.

  As described above, the alternative response system, the exchange, and the alternative response method according to the present invention are based on the alternative response setting registration condition registered in the exchange by the owner of the mobile phone, and the ring tone of the mobile phone of the absent person is used. Instead of directly operating the mobile phone of the absent person, an alternative call can be made by making a call to the mobile phone that is ringing using its own mobile phone or landline phone. .

  In addition, the acceptable condition for the alternative response is determined by appropriately determining the position of the mobile phone of the absentee, the position of the alternative response terminal, and the time of the alternative response. An alternative response can be realized by a specific location, a specific time, and a specific terminal.

  Therefore, it becomes possible to encourage more active alternative calls to people who feel resistance to operating other people's mobile phones. After that, it is possible to avoid a situation in which a disadvantage occurs for the absentee, and to improve the opportunity for an alternative call to the absentee's mobile phone at the office or home.
