  2. Description of the Related Art In recent years, Internet telephone adapters that make it possible to use telephones for public switched telephone networks as Internet telephones have become widespread. This Internet phone adapter is generated by a tone generator with built-in tones such as dial tone, busy tone, and ring back tone when a user makes a call or when a user ends communication. To output these tones. As a result, the user can listen to the same voice as a conventional telephone using the public switched telephone network from the telephone handset.

However, a user of a telephone for a public exchange telephone network using the Internet telephone adapter has a disadvantage that the situation of the other party is not well understood at the time of communication only with the above tone.
As a technique for solving the above problems, a technique has been proposed in which when a telephone call is made from an Internet telephone device or a telephone call is received, the other party's situation is voiced from a telephone handset (see, for example, Patent Document 1). .

  As a related technique, when all the lines connected to the service RAS (Remote Access Server) are busy, the RAS for waiting receives a newly generated dial-up connection request, and then this connection request. Has been proposed (see, for example, Patent Document 2), in which the waiting server provides appropriate service information to the client using TCP / IP communication.

In addition, when an incoming call is connected to queue data, a technique has been proposed in which the order of the incoming call connected to the queue data is notified from the exchange to the caller telephone and the user's personal computer (see, for example, Patent Document 3). .

When information indicating that a session with #E called telephone device 31 is possible, voice notification server 20 receives voice data representing information indicating that a session with #E called telephone device 31 is possible. And this data is output to the SIP server 10.
When voice data representing session establishment waiting information is input from voice notification server 20, control unit 11 of SIP server 10 generates an IP packet having the input voice data, and then #D calling side telephone device The generated IP packet is transmitted to 30 user agents 35 via a wireless network or a wired network.

  When receiving the IP packet having the display data, the user agent 35 of the #D calling side telephone device 30 causes the speaker to output the voice data (see FIG. 10A). That is, the user agent 35 of the #D calling side telephone device 30 causes the speaker to output the session establishment waiting information “can be connected” (see 13 in FIG. 4 and FIG. 10A).

  Thereafter, in order to establish a session with the #E called telephone device 31, the user agent 35 of the #D calling phone device 30 communicates with the user agent 36 of the #E called phone device 31. An INVITE message for requesting connection is transmitted to the SIP server 10 via a wireless network or a wired network (see 14 in FIG. 4).

  When the control unit 11 of the SIP server 10 receives the INVITE message from the user agent of the #D calling side telephone device 30 via the wireless network or the wired network, the #D transmission stored in the queue 122 of the storage unit 12 is transmitted. The telephone number “050-1234976” of the side telephone device is activated. Next, the SIP server 10 performs the same process as described above, and receives the INVITE message previously received from the user agent 35 of the #D calling telephone device 30 as the user agent of the #E called telephone device 31. 36 via the Internet 40 (see 14 and 15 in FIG. 4).

  After that, when receiving a 100 Trying message from the user agent 36 of the #E called telephone device 31 via the Internet 40, the control unit 11 receives the 100 Trying message of the #D calling phone device 30 in the same manner as described above. It transmits to the agent 30 via a wireless network or a wired network (see 16 and 17 in FIG. 4).

Next, when receiving the 180 Ringing message from the user agent 36 of the #E called telephone device 31 via the Internet 40, the control unit 11 receives the Ringing message in the same manner as described above. The data is transmitted to the agent 30 of the device 30 via a wireless network or a wired network (see 18 and 19 in FIG. 4).
Thereafter, the user agent 36 of the #E called telephone device 31 transmits a 200 OK message indicating acceptance of connection to the SIP server 10 via the Internet 40 (see 20 in FIG. 4).

  When receiving the 200 OK message, the control unit 11 of the SIP server 10 transmits the URI described in the 200 OK message to the location server, and the IP address “192.168.10. .11 ". Thereafter, the control unit 11 converts the domain name (d-eigyosho.co.jp) in the URI described in the 200 OK message received from the user agent 36 of the #E called telephone device 31 to the IP address (“ 050-12349876@192.168.10.11 "). After that, the control unit 11 sends a 200 OK message in which the IP address is described to the user agent 35 of the #D calling side telephone device 30 via the wireless network or the wired network, to the user agent 35 of the #D calling side telephone device 30. (See 21 in FIG. 4).

  Then, the user agent 35 of the #D calling side telephone device 30 transmits an ACK message indicating that the 200 OK message has been received to the SIP server 10 via the wireless network or the wired network (see 22 in FIG. 4). . Here, in the ACK message, a URI “050-22223333@e-eigyosho.co.jp” is described.

When the control unit 11 of the SIP server 10 receives the ACK message from the user agent 35 of the calling side telephone device 30 of #D, it transmits the URI described in the ACK message to the location server, and the ## of the receiving side from the location server. The IP address “192.168.2.1” assigned to the destination telephone device 31 of E is received. Thereafter, the control unit 11 rewrites the domain name in the URI described in the ACK message previously received from the user agent 35 of the #D calling telephone device 30 with the IP address “050-22223333@192.168”. Generates an ACK message in which “2.1” is described.
Thereafter, the control unit 11 transmits the ACK message generated via the Internet 40 to the user agent 36 of the #E called telephone device 31 (see 23 in FIG. 4). Subsequently, the control unit 11 deletes the telephone number of the #D calling side telephone device stored in the queue 122 of the storage unit 12 (see FIG. 10B). Thereafter, a session is established between the #D calling side telephone device 30 and the #E receiving side telephone device 31 and shifts to a state in which a call can be made (see 24 in FIG. 4).

Thereafter, after a call is made between the #D calling side telephone device 30 and the #E receiving side telephone device 31, the user agent 35 of the #D calling side telephone device 30 sends a BYE message for canceling the connection to the Internet. When the user agent 36 of the #E called telephone device 31 receiving the BYE message receives the BYE message, the user agent 36 accepts the connection cancellation request. Is transmitted to the user agent 35 of the #D caller telephone device 30 via the Internet 40 (see 26 in FIG. 4), and the process is terminated.
When the user agent 35 of the #D calling side telephone device 30 receives the 200 OK message from the user agent 35 of the #E receiving side telephone device 31, the process is terminated.

  Next, an operation for changing the order of waiting for session establishment in the embodiment will be described with reference to FIG.

FIG. 11 is a flowchart showing an operation of changing the order of waiting for establishment of sessions performed by the SIP server.
The control unit 11 of the SIP server 10 determines whether or not the order key value is received from the calling side telephone device 30 via the wireless network or the priority network (step S10). When it is determined that the order key value has not been received (step S10; NO), the control unit 11 performs the same processing until the order key value is received. On the other hand, if the control unit 11 determines that the order key value is received from the calling side telephone device 30 of the telephone number stored in the queue 122 of the storage unit 12 (step S10; YES), the control unit 11 sets the order key value. The corresponding priority value is read from the order key information list 123 stored in the storage unit 12 (step S11).

Next, the control unit 11 refers to the priority number cumulative value information list 124 stored in the storage unit 12. Then, the priority number cumulative value information corresponding to the telephone number of the calling side telephone device 30 is read out, and a value obtained by adding the previously read priority numerical value to this value is set as a new priority number cumulative value information list. The accumulated priority value corresponding to the telephone number in 124 is updated (step S12: order determination step).
For example, as shown in FIG. 12A, the calling side telephone device 30 that has transmitted the order key value to the SIP server 30 is the #D calling side telephone device 30, and the order key value is “a”. It shall be. Also, as shown in FIG. 12B, the cumulative priority number corresponding to the telephone number of the #D calling telephone device 30 registered in the cumulative priority number information list 124 is “0”. Then, the priority number cumulative value corresponding to the telephone number of the calling side telephone device of #D in the priority number cumulative value information list 124 is updated to “2”.

Thereafter, the control unit 11 determines whether or not a telephone number having a higher priority for waiting for session establishment than the telephone number of the originating telephone device 30 that has transmitted the order key value is stored in the queue 122 (step S13). . When the control unit 11 determines that a telephone number having a higher priority for waiting for session establishment than the telephone number of the originating telephone device 30 that has transmitted the order key value is not stored in the queue 122 (step S13; NO) ), The process of changing the priority of waiting for establishment of this session is terminated.
On the other hand, when the control unit 11 determines that a telephone number having a higher priority for waiting for session establishment than the telephone number of the originating telephone device 30 that has transmitted the order key value is stored in the queue 122 (step S13). YES), it is determined whether the telephone number with the highest priority that has not yet been read is stored in the queue 122 (step S14).

  For example, as shown in FIG. 13A, the telephone number stored in the queue 122 is that the telephone number of the calling side telephone device 30 of #A is active, and the telephone number of the terminal end 30 of #B #D telephone that has sent the order key value is “1”, which has the highest session establishment waiting order, and “2”, which has the next highest session establishment waiting order of the telephone number at the end of the telephone end 30 of #C. If the session establishment waiting order of the telephone number at the end of terminal 30 is “3”, which is the lowest, #B having a higher session establishment waiting order than the telephone number of the originating side telephone device 30 of #D that has transmitted the order key value. And the control unit 11 determines that the telephone number of the calling side telephone device 30 of #C is stored in the queue 122 (order variation determination step).

  When it is determined that the telephone number with the highest priority that has not yet been read is not stored in the queue 122 (step S14; NO), the control unit 11 ends the process. On the other hand, when the control unit 11 determines that the highest priority telephone number that has not yet been read is stored in the queue 122 (step S14; YES), the highest priority that has not yet been read. A telephone number with a high is read from the queue 122 (step S15).

  Next, the control unit 11 refers to the priority number cumulative value information list 124 and determines whether the priority number cumulative value of the telephone number read from the queue 122 is larger than the priority number cumulative value of the telephone number that has transmitted the order key value. It is determined whether or not (step S16). When the control unit 11 refers to the priority number cumulative value information list 124 and determines that the priority number cumulative value of the telephone number read from the queue 122 is larger than the priority number cumulative value of the telephone number that has transmitted the order key value. (Step S16; YES), the process proceeds to step S14, and the same processing as described above is continued (order variation determination step).

  For example, as shown in FIG. 13A, the telephone number read from the queue 122 is the telephone number of #B, and the cumulative number of priority numbers of this telephone number is “4” as shown in FIG. In the case of "#", the cumulative number of priority numbers of the telephone number of the calling side telephone device 30 of #B is larger than the cumulative number of priority numbers of the telephone number of the calling side telephone device 30 of #D that has transmitted the order key value. It is determined by the control unit 11.

  On the other hand, the control unit 11 refers to the priority number cumulative value information list 124 and determines that the priority number cumulative value of the telephone number read from the queue 122 is equal to or less than the priority number cumulative value of the telephone number that has transmitted the order key value. If it is determined (step S16; NO), in the queue 122, the telephone number of the originating side telephone device 30 that has transmitted the order key value is set higher in the session establishment waiting order than the previously read telephone number (step S17). : Order changing step)).

  For example, when the telephone number read from the queue 122 is the telephone number of the calling side telephone device 30 of #C and the cumulative number of priority numbers of this telephone number is “0” as shown in FIG. The control unit 11 determines that the cumulative number of priority numbers of the telephone number of the #C calling side telephone device 30 is equal to or less than the cumulative number of priority numbers of the telephone number of the #D calling side telephone device 30 that has transmitted the order key value. Is determined. Then, as shown in FIG. 13 (b), the session establishment order of the telephone number of the #D calling side telephone device 30 is changed from "3" to "2" by the control unit 11, and the #C transmission is made. The order of waiting for session establishment of the telephone number of the side telephone device 30 is changed from “2” to “3” by the control unit (order changing step).

  Thereafter, the control unit 11 transmits information indicating that the order of waiting for session establishment has been changed to the caller telephone device 30 via the wireless network or the priority network (step S18), and ends the process.

  Of the information processing steps described above, in the identification information processing step, the session establishment wait information generation step, and the session establishment wait information transmission step, the execution contents are programmed and executed by a computer. May be.

As described above, according to the first embodiment, the SIP server 10 transmits the generated session establishment waiting information to the calling side telephone devices 30 of #A to #D where the session cannot be established. The users of #A to #D calling side telephone devices 30 can know the current session waiting state, and can prevent frequent repeated calls due to connection anxiety.
Further, according to the first embodiment, since the SIP server 10 transmits the session establishment waiting information including the display data and the voice data to the #A to #D calling side telephone devices 30, #A to #D , For example, can display session establishment waiting information on a liquid crystal display device, and can cause the speaker to output the session establishment waiting information as audio.

Further, according to the first embodiment, since the SIP server 10 generates session waiting information in the order of waiting for session establishment, the users of the calling side telephone devices 30 of #A to #D that have received the session waiting information are , You can know the order of session establishment.
Furthermore, according to the first embodiment, the numerical information corresponding to the key identification information received from the user by the SIP server 10 is added to the priority numerical value cumulative value corresponding to the telephone number of the caller telephone device 30 of the user. Since it did in this way, the order of waiting for establishment of a session can be changed by the user himself.

Second Embodiment
FIG. 14 is a block diagram showing the configuration of the SIP server 10 that constructs the communication control system according to the second embodiment of the present invention.
Here, the same reference numerals are assigned to the same components as those of the first embodiment, and different reference symbols are assigned to different components.

  As shown in FIG. 1, the SIP server 10 is connected to the voice communication server 20 and to a plurality of calling side telephone devices 30 via a wireless network or a wired network as shown in FIG. In addition, it is connected to the receiving side telephone device 31 via the Internet 40. And the SIP server 10 is provided with the control part 11, the memory | storage part 12, and the transmission / reception I / F part 13 like the thing of 1st Embodiment, as shown to Fig.14 (a).

The storage unit 12 includes a control program storage area 121 that stores a control program, a queue 122 that is the same as that of the first embodiment, and a telephone number priority value information list 125.
As shown in FIG. 14B, the telephone number priority numerical value information list 135 is registered with telephone number priority numerical value information including a telephone number item and a priority numerical value item. The telephone number item describes the telephone number of the calling telephone device 30 waiting for session establishment, and the priority numerical value item describes the above-described priority numerical value.

Next, the operation of the incoming call waiting information supply system according to the second embodiment of the present invention will be described.
In the incoming call waiting information supply system in this embodiment, when the call origination telephone apparatus 30 waits for establishment of a session with the callee telephone apparatus 31, the call waiting telephone apparatus 30 displays the status of waiting for each part of the session. The operation for notifying is the same as that of the first embodiment. On the other hand, in the second embodiment, the operation for changing the session establishment waiting order is different from that in the first embodiment.
Hereinafter, the operation of this different part will be described.

  FIG. 15 is a flowchart showing an operation of changing the priority of session establishment waiting priority performed by the SIP server. After the calling side telephone device 30 transmits a connection request to the called side telephone device 31 via the SIP server 10, the control unit 11 of the SIP server 10 responds to the connection request of the calling side telephone device 30. When the BUSY message is received from 31 (step S20), the priority value information list 125 by telephone number stored in the storage unit 12 is referred to, and the priority numerical value corresponding to the telephone number of the caller telephone device 30 is read (step S21). . For example, as shown in FIG. 6A, when the #D calling side telephone terminal 30 transmits a connection request to the #E receiving side telephone terminal 31, and the SIP server 10 receives the calling side telephone device. When the BUSY message of the calling side telephone device 30 of #D from 31 is received, the priority value read by the control unit 11 is “2” as shown in FIG.

After that, the control unit 11 reads the priority numerical value for the telephone number with the highest priority that has not yet been read from the queue 122 from the telephone number priority value information list 125 (step S22). For example, as shown in FIG. 16B, when the telephone numbers of #A, #B, and #C of the calling side telephone device 30 are stored in the queue 122, the priority number information list for each telephone number 125 The priority value read out is “3” of the calling side telephone device 30 of #C.
(See FIG. 14B).

  Next, the control unit 11 determines whether or not the priority numerical value of the calling telephone device 30 that has received the BUSY message (busy message) is larger than the priority numerical value for the telephone number of the calling telephone device read from the queue 122. Is determined (step S23). When the control unit 11 determines that the priority numerical value of the calling telephone device 30 that has received the BUSY message is larger than the priority numerical value for the read telephone number of the calling telephone device (step S23; YES), The telephone number of the caller telephone device 30 that has received the BUSY message is stored in the queue establishment queue 122 where the priority for waiting for session establishment is higher than the telephone number of the caller telephone device that has read the message (step S24). The process is terminated.

  For example, as shown in FIG. 14B, in the case of #D calling side telephone device 30 as the calling side telephone device 30 that has received the BUSY message, it corresponds to the telephone number of #D calling side telephone device 30. Since the priority numerical value “2” is larger than the priority dynamic value “1” corresponding to the telephone numbers of #A and #B transmitting side telephone devices 30, as shown in FIG. The telephone numbers of the telephone devices 30 are stored in the queue 122 of the session establishment order “2” in which the priority of waiting for session establishment is higher than the telephone numbers of the calling side telephone devices 30 of #A and #B.

  On the other hand, when it is determined that the priority numerical value of the calling telephone device 30 that has received the BUSY message is less than the priority numerical value for the read telephone number (step S23; NO), the control unit 11 still reads it. It is determined whether or not the telephone number of the calling telephone device 30 with the highest priority that has not been stored is stored in the queue 122 (step S25).

  If the telephone number of the caller telephone device 30 with the highest priority that has not yet been read is not stored in the queue 122 (step S25; NO), the control unit 11 receives the BUSY message. The telephone number of the device 30 is stored in the location of the queue 122 having the lowest priority as the session establishment waiting order (step S26), and the process is terminated. On the other hand, when the telephone number with the highest priority that has not yet been read is stored in the queue 122 (step S25; YES), the control unit 11 proceeds to step S22 and performs the same process as described above. To continue.

  Thereafter, the control unit 11 indicates that the waiting for establishment of the session has changed, and information indicating that the priority has been changed for the calling side telephone device 30 whose priority of the telephone number stored in the queue 122 has been changed. Is transmitted via the wireless network or the priority network (step S27), and the process is terminated. Other configurations and the effects thereof are the same as those of the first embodiment described above.

  Even in this case, when a session establishment waiting occurs between the calling-side telephone device 30 and the called-side telephone device 30, the same effects as those of the first embodiment described above can be obtained. Further, according to the second embodiment, the priority value information for each telephone number that is stored in a pair of the priority numerical value for determining the waiting order for establishment of the session and the telephone number assigned to the calling side telephone device 30. Since the list 125 is included, the SIP server 10 can set the order of waiting for session establishment of the caller telephone device when the caller telephone device becomes unable to establish a session.

<Third Embodiment>
Next, a third embodiment of the present invention will be described with reference to FIG.
FIG. 17 is a block diagram showing the SIP server 10 constituting the main part of the third embodiment. Here, the same reference numerals are given to the same components as those of the above-described embodiments.

  As in the first and second embodiments (FIG. 1), the SIP server 10 is connected to the voice communication server 20 and to a plurality of calling side telephone devices 30 via a wireless network or a wired network. In addition, it is connected to the receiving side telephone device 31 via the Internet 40. And this SIP server 10 is provided with the control part 11, the memory | storage part 12, and the transmission / reception I / F part 13 like the thing of 1st Embodiment, as shown to Fig.17 (a).

As shown in FIG. 17 (a), the SIP server 10 is a component different from those in the first and second embodiments, and the order key information list 123 in the first embodiment as shown in FIG. Instead of the user action information list 126 (user action information storage step).
In the user action information list 126, as shown in FIG. 17B, user action information having an action content item and a priority number addition value item is registered. The action content item describes the content of the action performed by the user waiting for session establishment, and the priority number addition value item describes the value to which the priority number cumulative value is added.

Next, the operation of the communication control system in the third embodiment according to the present invention will be described.
In the communication control system according to the third embodiment, when a session establishment wait occurs between the caller telephone device 30 and the callee telephone device 31, the operation for informing the caller telephone device 30 of session establishment wait information. Is the same as that of the first and second embodiments. On the other hand, in the third embodiment, the operation for changing the priority of waiting for establishment of a session is different from that in the first and second embodiments described above. Therefore, this different operation will be described below.

  FIG. 18 is a flowchart showing an operation of changing the session establishment waiting order performed by the SIP server. When the user action information that changes the priority number cumulative value list 124 is generated from the calling telephone device 30 waiting for establishment of a session (Step S30), the control unit 11 of the SIP server 10 has user action information stored in the storage unit 12. Referring to list 126, the priority number addition value corresponding to the generated action information is read (step S31). Thereafter, the control unit 11 adds and updates the read priority number addition value to the priority accumulation value corresponding to the telephone number of the corresponding caller telephone device 30 in the priority number accumulation value list 124 (step S32). : Addition process).

  For example, when action information indicating that the waiting time for session establishment by #D originating telephone device 30 has passed 15 minutes has occurred, as shown in FIG. "2" is read out. Then, the priority number cumulative value corresponding to the telephone number of the #D calling side telephone device 30 in the priority number cumulative value information list 124 is updated from “0” to “2” as shown in FIG.

  Thereafter, the control unit 11 determines whether or not a telephone number having a higher priority for waiting for session establishment than the telephone number of the calling telephone device 30 where the user action information is generated is stored in the queue 122 (step S33). When the control unit 11 determines that a telephone number having a higher priority for waiting for session establishment than the telephone number of the calling side telephone device 30 in which the user action information is generated is not stored in the queue 122 (step S33; NO) Then, the priority change processing for waiting for establishment of this session is terminated. On the other hand, when the control unit 11 determines that a telephone number having a higher priority for waiting for session establishment than the telephone number of the calling telephone device 30 in which the user action information is generated is stored in the queue 122 (step S33; YES), it is determined whether or not the highest priority telephone number that has not yet been read is stored in the queue 122 (step S34).

  For example, as shown in FIG. 20A, the telephone number stored in the queue 122 is that the telephone number of the calling side telephone device 30 of #C is active, and the telephone number of the calling side telephone device 30 of #A The number is stored in the place of the session establishment waiting order “1” having the highest priority, and the telephone number of the calling side telephone device 30 of #B is placed in the place of the session establishment waiting order “2” having the next highest priority. When the action information is generated when the telephone number of the #D calling telephone device 30 of the #D before the action information is generated is stored in the session establishment waiting order “3” having the lowest priority. When the telephone number of the #A calling side telephone device 30 having a higher priority for waiting for session establishment than the telephone number of the #D calling side telephone device 30 is stored in the queue 122, the control unit 11 It is determined.

  When it is determined that the telephone number with the highest priority that has not yet been read is not stored in the queue 122 (step S34; NO), the control unit 11 ends the process. On the other hand, when it is determined that the highest priority telephone number that has not yet been read is stored in the queue 122 (step S34; YES), the control unit 11 has the highest priority that has not yet been read. The telephone number having a higher value is read from the queue 122 (step S35).

  Next, the control unit 11 refers to the priority number cumulative value information list 124, and the priority number cumulative value of the telephone number read from the queue 122 is the cumulative priority number of the telephone number of the calling side telephone device 30 in which the user action has occurred. It is determined whether or not the value is larger (step S36). When the control unit 11 determines that the cumulative number of priority numbers of the telephone number read from the queue 122 is larger than the cumulative number of priority numbers of the telephone number of the calling side telephone device 30 in which the user action has occurred (step S36; YES) ), The process proceeds to step S34, and the same processing as described above is continued.

  For example, when the telephone number read from the queue 122 is the telephone number of the calling side telephone device 30 of #A and the cumulative number of priority numbers of this telephone number is “3” as shown in FIG. 19, Control unit 11 determines that the cumulative number of priority numbers of #A calling telephone device 30 is larger than the cumulative number of priority numbers of #D calling telephone device 30 in which action information has been generated.

  On the other hand, the control unit 11 refers to the priority number cumulative value information list 124, and the priority number cumulative value of the telephone number of the calling side telephone device 30 read from the queue 122 is the telephone of the calling side telephone device 30 where the action information is generated. When it is determined that the priority number is less than or equal to the cumulative number of priority numbers corresponding to the number (step S36; NO), the telephone number of the calling side telephone device 30 in which the user action has occurred in the queue 122 is determined from the previously read telephone number. The priority is increased (step S37).

For example, when the telephone number read from the queue 122 is the telephone number of the calling side telephone device 30 of #B and the cumulative number of priority numbers of this telephone number is “1” as shown in FIG. The control unit 11 determines that the priority number cumulative value of the telephone number of the B calling side telephone device 30 is equal to or less than the priority number cumulative value of the telephone number of the #D calling side telephone device 30 in which the action information is generated. Then, as shown in FIG. 20 (b), the session establishment order of the telephone number of the #D calling side telephone device 30 is changed from “3” to “2” by the control unit 11, and the transmission of #B is performed. The order of waiting for session establishment of the telephone number of the side telephone device 30 is changed from “2” to “3” by the control unit.
Thereafter, the control unit 11 transmits information indicating that the order of waiting for session establishment has been changed to the caller telephone device 30 via the wireless network or the priority network (step S38), and ends the process.

According to this embodiment, when the caller side call device 30 waits for establishment of a session with the callee side phone device 31, the same effect as that of the first embodiment is obtained.
According to this embodiment, when the SIP server 10 generates user action information, the numerical information corresponding to the action content is added to the priority numerical value cumulative value corresponding to the telephone number of the user calling telephone device 30. Therefore, it is possible to finely change the setting of the order of waiting for session establishment.

  As described above, in the communication control system according to each of the first to third embodiments described above, a telephone number is used as a URI for designating the receiving-side telephone device 31 that the transmitting-side telephone device 30 transmits to the SIP server 10. However, in addition to this, a user ID for designating a user may be described instead of a telephone number. In this case, in the address conversion table included in the location server, address conversion data in which a URI in which a user ID and a domain name are described and an IP address are paired is registered.

It is a block diagram which shows the structure of 1st Embodiment of this invention. It is a block diagram which shows the structure of the SIP server in FIG.
