Description

  The present invention relates to a main device, and more particularly to a technique for notifying the presence of a wireless telephone terminal to a call originator destined for a subordinate wireless telephone terminal.

  Conventionally, the presence (whether present or absent) of each subordinate telephone terminal is managed, and when a call destined for the absent telephone terminal arrives, an absent talk key is transmitted to the call originator. Main devices having functions are known. For example, Patent Document 1 discloses a premises that can notify the status of a call partner without causing the call originator to wait longer than necessary even when the call partner requesting the agent is absent. An exchange is disclosed.

  By the way, since a radio telephone terminal such as PHS is normally carried by a user, there is no concept of whether the user is present or absent. For this reason, the main device having the presence function that accommodates the wireless telephone terminal manages the presence of the subordinate wireless telephone terminal depending on whether it is within the service area or out of service area, and when a call is received that is addressed to a wireless telephone terminal outside the service area Send out-of-service talkies to the originator of this call.

  However, the user may not be able to answer the phone even within a range such as during a meeting. Further, when the user is out of service area due to a business trip or the like, the user may want to notify the call originator that the user is on a business trip rather than the out-of-service talkie. A conventional main apparatus having a presence function does not consider such a case and is not convenient.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to describe the state of a wireless telephone terminal in more detail when a call to a wireless telephone terminal in a state where it cannot respond is received. It is to provide a technology that can be informed.

  In order to solve the above-described problems, in the present invention, the main apparatus can accept presence information registration requests and deletion requests from subordinate radio telephone terminals. If the main apparatus accepts the presence information registration request, the main apparatus registers the presence information in association with the registration request transmission source radio telephone terminal. If the main apparatus accepts the deletion request, the main apparatus registers the presence information. The presence information registered in association with the telephone terminal is deleted.

  In addition, when a call arrives at a subordinate radio telephone terminal as a destination, if the telephone terminal is in a state where it cannot answer, the details of the radio telephone terminal are responded to the incoming call. A talkie is sent to the call originator that informs the user of the situation.

  Specifically, presence information associated with the wireless telephone terminal is registered, and the priority included in the presence information indicates that the presence specified by the presence information is given priority. In this case, a talkie corresponding to the presence specified by the presence information is transmitted. In addition, when presence information corresponding to the wireless telephone terminal is registered and the priority included in the presence information indicates that the presence specified by the presence information is not prioritized, If the wireless telephone terminal is within range, a talkie corresponding to the presence specified by the presence information is transmitted. If the wireless telephone terminal is out of range, a talkie indicating that the wireless telephone terminal is out of range is transmitted. Further, when the presence information corresponding to the wireless telephone terminal is not registered and the wireless telephone terminal is out of the service area, a talkie indicating that the wireless telephone terminal is out of service is transmitted.

For example, the main device of the present invention is a main device that processes call control for each subordinate radio telephone terminal,
For each of the subordinate radio telephone terminals, terminal monitoring means for monitoring whether the radio telephone terminal is within range or out of range;
Presence information storage means for storing presence information including the presence priority of the presence of the wireless telephone terminal and the monitoring result of the terminal monitoring means for each of the subordinate wireless telephone terminals;
Request accepting means for accepting presence information registration request with presence information or presence information deletion request from each of the subordinate radio telephone terminals;
When the request accepting unit accepts the presence information registration request accompanied by the presence information, the presence information is stored in the presence information storage unit in association with the transmission source of the presence information registration request, and the request A storage control unit that deletes the presence information stored in the presence information storage unit in association with a transmission source of the presence information deletion request when the reception unit receives the presence information deletion request;
A talkie storage means for storing a talkie for notifying the presence for each preset presence including out of service area;
Automatic response means for transmitting a talkie stored in the talkie storage means to a call originator in response to an incoming call addressed to the subordinate radiotelephone terminal;
The automatic response means includes
The presence information stored in the presence information storage means in association with the destination of the call, and the priority included in the presence information gives priority to the presence specified by the presence information. In response to the incoming call, the talkee corresponding to the presence specified in the presence information is read from the talkie storage means and transmitted.
The presence information is stored in the presence information storage means in association with the call destination, and the priority included in the presence information does not give priority to the presence specified by the presence information. If the monitoring result of the destination of the call by the terminal monitoring means is within range in response to the arrival of the call, the talkie corresponding to the presence specified by the presence information is displayed as the monitoring result. If it is out of range, a talkie indicating that it is out of range is read out from the talkie storage means and transmitted,
When the presence information is not stored in the presence information storage unit in association with the call destination, and the monitoring result of the call destination by the terminal monitoring unit is out of service area, In response, a talkie indicating that it is out of range is read from the talkie storage means and transmitted.

  According to the present invention, when a call to a wireless telephone terminal that cannot be answered arrives, the state of the wireless telephone terminal can be notified to the call originator in more detail.

  FIG. 4B is a diagram schematically illustrating an example of registered contents in the presence information storage unit 16. As shown in the figure, a record 1600 is registered in the presence information storage unit 16. A record 1600 includes a field 1601 for registering a terminal address of a presence information registration request source (IP telephone terminal 3 or wireless IP telephone terminal 4), and a field 1602 for registering a presence identification code received from a user of the presence information registration request source. When the presence end time is received from the presence information registration requesting user, the field 1603 for registering the end time, and when the presence information registration requesting source is the wireless IP telephone terminal 4, And a field 1604 for registering the priority received from the user of the terminal 4. Here, the priority refers to whether or not the presence notification received from the user of the wireless IP telephone terminal 4 has priority over the notification of the in-range / out-of-range state with respect to the call originator of the wireless IP telephone terminal 4 It is information that specifies.

  The call control unit 17 performs call control of each of the IP telephone terminal 3 and the wireless IP telephone terminal 4 using station data stored in the station data storage unit 12 in accordance with a call control protocol such as SIP (Session Initiation Protocol). To process.

  The automatic answering unit 18 responds to an incoming call when the IP telephone terminal 3 or the wireless IP telephone terminal 4 cannot respond to an incoming call with the IP telephone terminal 3 or the wireless IP telephone terminal 4 as a destination. In response, the talk key stored in the talk key storage unit 13 or the voice message stored in the voice message storage unit 14 is transmitted to the call originator.

  The presence manager 19 manages the presence of each of the IP telephone terminal 3 and the wireless IP telephone terminal 4. As illustrated, the presence management unit 19 includes a request reception unit 191, an event acquisition unit 192, a terminal monitoring unit 193, and a storage control unit 194.

  The request receiving unit 191 receives a presence information registration request or deletion request from the IP telephone terminal 3 or the wireless IP telephone terminal 4.

  The event acquisition unit 192 acquires event information of an ongoing event from the schedule management device 2. The event information includes the terminal address of the schedule management target IP telephone terminal 3 or wireless IP telephone terminal 4 (schedule management target terminal), the presence identification code of the schedule management target terminal during the event, the end time of the event, And presence priority (however, presence priority is included only when the schedule management target terminal is the wireless IP telephone terminal 4).

  The terminal monitoring unit 193 monitors the out-of-service state / out-of-service state of each of the wireless IP telephone terminals 4. Then, the in-range / out-of-range state storage unit 15 is updated according to the monitoring result.

  The storage control unit 194 updates the presence information storage unit 16 and the voice message storage unit 14 in accordance with the presence information registration request or deletion request received by the request reception unit 191. Further, the presence information storage unit 16 is updated according to the event information acquired by the event acquisition unit 192.

  FIG. 5 is a flowchart for explaining the in-service / out-of-service state monitoring processing of the main apparatus 1 shown in FIG. This flow is started, for example, when the in-range / out-of-range state monitoring timing comes regularly.

  The terminal monitoring unit 193 selects an unselected record 1500 from the within-range / out-of-range state storage unit 15 (S101), and a survival confirmation message (with a destination address as a terminal address registered in the field 1501 of the selected record 1500) For example, PING) is sent to the LAN 7 via the network IF unit 11 (S102). Then, it waits for a response to the existence confirmation message for a predetermined time (S103).

  Next, if the terminal monitoring unit 193 receives a response to the existence confirmation message from the LAN 7 via the network IF unit 11 within a predetermined time (YES in S103), the terminal monitoring unit 193 registers in the field 1502 of the selected record 1500. The within-range / out-of-range state is updated to “range” (S104).

  On the other hand, if the terminal monitoring unit 193 does not receive a response to the existence confirmation message within a predetermined time (NO in S103), the terminal monitoring unit 193 sets the range / out-of-range state registered in the field 1502 of the selected record 1500 to “out-of-range”. (S105).

  Then, the terminal monitoring unit 193 checks whether or not an unselected record 1500 is registered in the within-range / out-of-range state storage unit 15 (S106). As a result, if there is an unselected record 1500 (YES in S106), the process returns to S101, and if there is no unselected record 1500 (NO in S106), this flow ends.

  FIG. 6 is a flowchart for explaining the event information acquisition process of the main apparatus 1 shown in FIG. This flow is started, for example, when event information acquisition timing comes regularly.

  The event acquisition unit 192 transmits an event information transmission request to the schedule management device 2 via the network IF unit 11 in order to acquire event information of an ongoing event from the schedule management device 2 (S111).

  Next, if the event acquisition unit 192 receives a response to the event information transmission request from the schedule management device 2 via the network IF unit 11, it determines whether or not event information is included in this response ( S112). If event information is not included in the response (NO in S112), this flow ends.

  On the other hand, if event information is included in the response (YES in S112), the event acquisition unit 192 selects unselected event information from the event information included in the response (S113), Event information is passed to the storage control unit 194.

  In response to this, the storage control unit 194 searches the presence information storage unit 16 for the record 1600 using the terminal address included in the passed event information as a key (S114). If the record 1600 can be retrieved from the presence information storage unit 16 (YES in S115), the storage control unit 194 includes the registered contents of the fields 1602-1604 of the record 1600 in the passed event information. The presence identification code, the event end time (presence end time), and the presence priority are updated (S116). However, when the presence event priority is not included in the passed event information, the field 1604 is left blank.

  On the other hand, when the record 1600 cannot be retrieved from the presence information storage unit 16 (NO in S115), the storage control unit 194 adds a new record 1600 to the presence information storage unit 16, and the fields 1601-1604 of this record 1600 The terminal address, presence identification code, event end time (presence end time), and presence priority included in the passed event information are registered (S117). However, if the selected event information does not include the presence priority, the field 1604 is left blank.

  Then, the event acquisition unit 192 determines whether unselected event information is included in the response to the event information transmission request (S118). If unselected event information is included (YES in S118), the process returns to S113. If unselected event information is not included (NO in S118), this flow ends.

  FIG. 7 is a flowchart for explaining the presence information automatic deletion processing of the main apparatus 1 shown in FIG.

  The storage control unit 194 periodically searches the records 1600 stored in the presence information storage unit 16 for the records 1600 whose end time registered in the field 1603 has arrived or passed (S121, S122). If the corresponding record 1600 can be searched (YES in S122), the terminal address registered in the field 1601 of this record 1600 is acquired, and then this record 1600 is deleted from the presence information storage unit 16 ( S123).

  Then, the storage control unit 194 searches the voice message storage unit 14 for the record 1400 using the terminal address registered in the field 1601 of the deleted record 1600 as a key (S124). If the record 1400 can be searched (YES in S125), the record 1400 is deleted from the voice message storage unit 14 (S126).

  Next, the storage control unit 194 notifies the request reception unit 191 of the terminal address registered in the field 1601 of the deleted record 1600 and instructs a deletion report. In response to this, the request receiving unit 191 generates a presence information deletion report message whose destination is the notified terminal address, and transmits the presence information deletion report message from the network IF unit 11 (S127).

  FIG. 8 is a flowchart for explaining the calling process of main apparatus 1 shown in FIG. This flow is started when the call control unit 17 receives dial information from the IP telephone terminal 3 or the wireless IP telephone terminal 4 (hereinafter referred to as a transmission source terminal) via the network IF unit 11.

  First, the call control unit 17 determines whether or not the destination number indicated by the dial information received from the caller terminal is a predetermined number for presence management assigned to the main device 1 (hereinafter referred to as a registered special number). Is determined (S131). If the destination number is not a registered special number (NO in S131), the call control unit 17 performs normal call processing according to a predetermined call control procedure (S144).

  On the other hand, when the destination number is a registered special number (YES in S131), the call control unit 17 instructs the request reception unit 191 to accept presence information. In response to this, the request accepting unit 191 sends a voice guidance prompting the user to input a presence information registration request or deletion request to the source terminal via the network IF unit 11, and accepts the request from the source terminal (S132). ).

  Next, if the request received from the caller terminal is a request to delete presence information (“delete” in S133), the request receiving unit 191 notifies the storage control unit 194 of the terminal address of the caller terminal. Instructs deletion of presence information. In response to this, the storage control unit 194 searches the presence information storage unit 16 for the record 1600 using the terminal address of the caller terminal as a key, and deletes this record 1600. Similarly, the record 1400 is searched from the voice message storage unit 14 using the terminal address of the caller terminal as a key, and if the record 1400 can be searched, it is deleted (S134).

  On the other hand, if the request received from the source terminal is a request for registration of presence information (“registration” in S133), the request reception unit 191 notifies the storage control unit 194 of the terminal address of the source terminal to indicate presence. Instructs the search for information. In response to this, the storage control unit 194 searches the presence information storage unit 16 for the record 1600 using the terminal address of the caller terminal as a key, and notifies the request reception unit 191 of the search result (S135).

  When the storage control unit 194 cannot retrieve the record 1600 from the presence information storage unit 16 using the terminal address of the transmission source terminal as a key (NO in S136), the request reception unit 191 sends the transmission source via the network IF unit 11. When a voice guidance for prompting input of presence information is transmitted to the terminal and presence information is received from the caller terminal, the presence information is notified to the storage control unit 194. In response to this, the storage control unit 194 adds a new record 1600 to the presence information storage unit 16, registers the terminal address of the caller terminal in the field 1601 of this record 1600, and stores the presence address in the fields 1602 to 1604. The presence identification code, presence end time, and presence priority included in the information are registered (S137). However, if the presence information does not include presence end time and priority, the fields 1603 and 1604 are left blank.

  On the other hand, when the storage control unit 194 can retrieve the record 1600 from the presence information storage unit 16 using the terminal address of the transmission source terminal as a key (YES in S136), the request reception unit 191 transmits the call via the network IF unit 11. The former terminal is notified that the presence information has been registered, and an inquiry is made to confirm the presence information update (S138). If the response to the inquiry received from the source terminal is “update cancel” (NO in S139), this flow is terminated without receiving presence information from the source terminal.

  On the other hand, if the response to the inquiry received from the transmission source terminal is “update execution” (YES in S139), the request reception unit 191 receives presence information from the transmission source terminal via the network IF unit 11, Presence information is notified to the storage control unit 194. In response, the storage control unit 194 stores the registered contents in the fields 1602 to 1604 of the record 1600 retrieved from the presence information storage unit 16 in S135, the presence identification code included in the presence information, the presence end time, And the priority of presence is updated (S140). However, if the presence information does not include presence end time and priority, the fields 1603 and 1604 are left blank.

  In this way, when new presence information is registered in the presence information storage unit 16 in S137, or when the registered presence information in the presence information storage unit 16 is updated in S140, the request reception unit 191 An inquiry about whether or not to register a voice message is made to the source terminal via the IF unit 11 (S141). If the response to the inquiry received from the caller terminal is “no voice message” (NO in S142), the flow ends without receiving a voice message from the caller terminal.

  On the other hand, if the response to the inquiry received from the source terminal is “voice message is present” (YES in S142), the request reception unit 191 receives the voice message from the source terminal via the network IF unit 11, This voice message is notified to the storage control unit 194. In response to this, the storage control unit 194 retrieves the record 1400 from the voice message storage unit 14 using the terminal address of the caller terminal as a key. If the record 1400 can be searched, the registered content in the field 1402 of the record 1400 is updated to the voice message received from the request receiving unit 191. If the record 1400 could not be searched, a new record 1400 is added to the voice message storage unit 14, and the terminal 140 of the source terminal and the voice message received from the request receiving unit 191 in the fields 1401 and 1402 of this record 1400. Is registered (S143).

  FIG. 9 is a flowchart for explaining the incoming call processing of main apparatus 1 shown in FIG. This flow is started when a call having the telephone number (terminal number) of the IP telephone terminal 3 or the wireless IP telephone terminal 4 as a destination number arrives at the call control unit 17 via the network IF unit 11.

  The call control unit 17 refers to the station data storage unit 12, identifies the terminal address corresponding to the destination number of the call, and notifies the automatic response unit 18 of this terminal address (S151). In response to this, the automatic response unit 18 searches the presence information storage unit 16 for the record 1600 using the terminal address received from the call control unit 17 as a key (S152).

  If the record 1600 can be retrieved from the presence information storage unit 16 using the terminal address received from the call control unit 17 as a key (YES in S153), the automatic response unit 18 stores the presence registered in the field 1604 of the record 1600. If the priority is “priority” (YES in S154), the record 1400 is further retrieved from the voice message storage unit 14 using the terminal address received from the call control unit 17 as a key (S155). If the automatic response unit 18 can retrieve the corresponding record 1400 from the voice message storage unit 14 (YES in S156), it automatically responds to the incoming call in cooperation with the call control unit 17, and The playback signal of the voice message registered in the field 1402 of this record 1400 is transmitted to the sender (S157). Thereafter, the call control unit 17 performs normal call control processing according to a predetermined call control procedure.

  Further, if the automatic response unit 18 cannot retrieve the corresponding record 1400 from the voice message storage unit 14 (NO in S156), the identification registered in the field 1602 of the record 1600 retrieved from the presence information storage unit 16 The record 1300 is retrieved from the talkie storage unit 13 using the code as a key (S158). Then, the automatic response unit 18 cooperates with the call control unit 17 to automatically answer an incoming call, and at the call source, the talkie registered in the field 1303 of the record 1300 retrieved from the talkie storage unit 13 The reproduction signal is transmitted (S159). Thereafter, the call control unit 17 performs normal call control processing according to a predetermined call control procedure.

  On the other hand, if the record 1600 could not be retrieved from the presence information storage unit 16 using the terminal address received from the call control unit 17 as a key (NO in S153), or retrieved from the presence information storage unit 16 using this terminal address as a key When the priority of the presence registered in the field 1604 of the record 1600 is “no priority” or blank (NO in S154), the automatic response unit 18 uses the terminal address received from the call control unit 17 as a key. The record 1500 is searched from the out-of-service state storage unit 15 (S160).

  When the record 1500 can be retrieved from the within-range / out-of-range state storage unit 15 using the terminal address received from the call control unit 17 as a key (YES in S161), the automatic response unit 18 is registered in the field 1502 of this record 1500. If the within-range / out-of-range state is “out-of-range” (YES in S162), the record 1300 is retrieved from the talkie storage unit 13 using the identification code assigned to the presence “out-of-range” as a key (S163).
