Description

  The present invention relates to an IP (Internet Protocol) telephone, and more specifically, includes an individual incoming key and a function key that can be assigned a call waiting (hereinafter referred to as CW) function, and an individual incoming call is made during a call. The present invention relates to an IP telephone in which the individual incoming call is moved to the function key assigned with the CW function.

  The applicant of the present invention previously provided an individual incoming key and a function key capable of assigning the CW function. When an individual incoming call is received during a call, the individual incoming call is assigned to the function key assigned the CW function. An IP telephone that has been moved has been proposed (Non-Patent Document 1).

  FIG. 8 is a schematic plan view of the appearance of the IP telephone 20. The IP telephone 20 includes a handset 21, a display unit 22 made up of an LCD, and an operation unit 23 made up of dial keys and various function keys.

  Here, for example, the called number “1111” can be assigned to the F1 key which is a function key, and the called number “2222” can be assigned to the F2 key. The F4 key is assigned a CW function, and the Pk key is assigned an individual incoming call function. The assignment of functions to these function keys is performed by a telephone contractor and cannot be performed or changed by the user.

By assigning the above functions to the F1, F2, F4, and PK keys, the IP telephone 20 operates as follows.
When an incoming call specifying the number “1111” is received from a SIP (Session Initiation Protocol) server (not shown) to the IP telephone set 20, a light emitting element provided corresponding to the F1 key (hereinafter referred to as a lamp of the F1 key). The same applies to other keys). When the user presses the F1 key and takes the handset 21 or presses the speaker key of the operation unit 23, the user is busy. The same applies when there is an incoming call specifying “2222”.

  In addition, when there is an incoming call specifying a called number (for example, “3456”, “7890”) that is not assigned to a function key (here, F1 key, F2 key), the PK key lamp is displayed. When the user presses the PK key and picks up the handset 21 or presses the speaker key, a call is in progress.

  The function of the F4 key will be described with reference to FIG. A in this figure is a diagram showing an operation when the CW function assigned to the F4 key is off and B is on.

  As shown in FIG. 9A, when the CW function is off, when there is an incoming call for the F1 key, that is, when there is an incoming call specifying “1111”, an incoming call for the F2 key, ie, incoming call specifying “2222”, and the PK key , Ie, “3456” and “7890” can be received.

  More specifically, the F1 key lamp blinks during an incoming call to the F1 key, and when there is a new incoming call to the F2 key, the F2 key lamp also blinks. In this state, by pressing the F1 key or the F2 key, it is possible to respond to an incoming call to the F1 key or the F2 key. In addition, if there is a new incoming call to the PK key during an incoming call to the F1 key, the PK key lamp also blinks. In this state, by pressing the PK key, it is possible to respond to an incoming call for the PK key. That is, priority is given to incoming calls to the PK key. The above is the case where there is an incoming call for the F2 key or the PK key during the incoming call for the F1 key. Similarly, when there is an incoming call for the F1 key and the PK key during the incoming call for the F2 key, Enable response or enable response to PK key.

  During a call using the F1 key, an incoming call to the F2 key is possible, but an incoming call to the PK key is impossible. More specifically, the F1 key lamp is lit during a call using the F1 key, and the F2 key lamp blinks when there is a new incoming call to the F2 key. By pressing the F4 key in this state, the F1 key and F4 key during a call are put on hold, and when the F2 key is pressed next, an incoming call to the F2 key can be answered. In addition, when the F4 key is pressed in this state, the F2 key during a call is put on hold, and the hold on the F1 key can be released. In this state, since the F4 key is kept on hold, if there is a new incoming call to the PK key, the IP telephone 20 rejects the incoming call.

  While incoming to the PK key, incoming to the F1 key and incoming to the F2 key are possible, but incoming to the PK key is not possible. Similarly, during a call using the PK key, incoming calls to the F1 key and incoming calls to the F2 key are possible, but incoming calls to the PK key are not possible.

  As shown in FIG. 9B, when the CW function is on, the operations during F1 and PK calls are the same as when the CW function is not assigned, but PK calls can be made during F1 calls and PK calls. Is different.

  More specifically, when there is an incoming PK during an F1 call, the F4 key lamp blinks. When the user presses the F4 key, the F1 key is put on hold and can respond to incoming PK calls. During this response, the F4 key is on hold and the PK key lamp is lit. When the F4 key is pressed in this state, the PK key is put on hold and the hold on the F1 key is released.

  Similarly, if there is a PK call during a PK call, the F4 key lamp blinks. When the user presses the F4 key, the F4 key is put on hold and a new PK incoming call can be answered. During this response, the F4 key lamp blinks on hold and the PK key lamp is lit. When the F4 key is pressed in this state, the PK key during a call is put on hold, and the hold of the F4 key is released.

  As described above, the IP telephone proposed by the applicant of the present invention assigns the CW function to the function key, and when there is an individual incoming call during a call, the individual incoming call is moved to the function key, so that only one line is provided. An IP telephone that cannot be used for an outside call can be used for a plurality of lines in appearance.

However, in this IP phone, the construction of the CW function and the ON / OFF setting are limited to construction contractors, and there is a problem that the user cannot set.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a diagram showing a configuration of an IP telephone system having an IP telephone apparatus according to an embodiment of the present invention.

  The IP telephone system according to the embodiment of the present invention includes an IP network 1, an IP telephone 2 and SIP server 3 connected to the IP network 1, and IP telephones 4 to 7 connected to the SIP server 3. This IP telephone system is an IP telephone service provided by a telecommunications carrier, and is a system that controls a telephone call by installing a SIP server.

  Here, extension numbers are set in advance and stored in the SIP server 3 so that the IP telephones 4 to 7 under the SIP server 3 function as extension telephones. Then, according to this setting information, the IP telephones 4 to 7 are connected to the IP telephone 2 and the IP telephones 4 to 7 via the SIP server 3 by the call connection control using SIP by the SIP server 3. An extension call is possible.

  FIG. 2 is a block diagram showing the configuration of the IP telephones 4 to 7 under the SIP server 3 in FIG. As shown in FIG. 2, the IP telephones 4 to 7 include a control unit 11, a storage unit 12, a call processing unit 13, a voice processing unit 14, an operation / display unit 15, and a network interface unit 16.

  The control unit 11 is composed of a microcomputer or the like, and controls the entire IP telephone. The storage unit 12 stores its own identification information such as terminal identification information, telephone number, IP address, and user ID of the IP telephone.

  The call processing unit 13 processes various messages for call connection using SIP and packets of the various identification information. The voice processing unit 14 includes a handset and a voice encoding / decoding processing circuit, and performs voice input / output and voice packet processing. The operation / display unit 15 has the same configuration as the operation unit 23 and the display unit 22 in FIG. 8, and includes various keys such as dial keys, function keys (F1 to F4 keys), and an LCD. Therefore, FIG. 8 is cited in the following description. Corresponding to the F1 key to F4 key, the PK key, and the speaker key, lamps for displaying the states are provided. The network interface unit 16 transmits and receives various packets between the IP network 1 and the call processing unit 13 and voice processing unit 14.

  Various functions can be assigned to the F1 to F4 keys, which are function keys. Here, the called numbers "1111" and "2222" are assigned to the F1 and F2 keys as external lines, respectively, and the CW function is assigned to the F4 key. Is assigned.

  Allocation of the CW function to the F4 key and its on / off setting are executed by a construction contractor when the IP telephone is installed. This setting is stored in the storage unit 12 as CCW function assignment information 12a and CW function on / off information 12b. As described above, in a conventional IP telephone, setting and changing of these information can be performed only by a construction contractor, but not by a user. In the present embodiment, the CW function on / off information 12b can be rewritten by the user pressing the F4 key. Based on the CW function on / off information 12b, the processes shown in FIGS. 9A and 9B can be executed.

  In the SIP server 3, a table is created in advance as shown in FIG. 3A that shows the correspondence between the called numbers of the subordinate IP phones 4 to 7 and the call destination. Here, the IP telephones 4 and 5 are called for an incoming call request specifying “1111”, the IP telephones 4 and 7 are called for an incoming call request specifying “2222”, and an incoming call specifying “5555”. In response to the request, the IP telephone 6 is called. In addition, the IP telephone 4 is called for an incoming call request specifying “3456” and “7890”.

  The storage unit 12 of the IP telephone 4 stores in advance a table showing the correspondence between the called number and the key of the operation / display unit 15 as shown in FIG. 3B. Then, when there is an incoming call specifying “1111” and “2222” from the SIP server 3, the lamps of the F1 key and the F2 key flash respectively under the control of the control unit 11. In addition, when there is an incoming call designating a number other than “1111” and “2222” (here, “3456” and “7890”), the PK key lamp blinks. A similar table is also stored in the storage unit 12 of the IP telephones 5 to 7.

  Next, the operation when the IP telephones 4 to 7 under the SIP server 3 are received will be described. Since the operations of the IP telephones 4 to 7 when receiving a call are basically the same, here, the IP telephone 4 will be described.

  FIG. 4 is a flowchart showing the operation when there is an individual incoming call during a call with the F1 key, F2 key or PK key in the IP telephone 4.

  First, the control device 11 reads the CW function assignment information 12a in the storage unit 12, determines whether or not the CW function is assigned (step ST1), and if there is an assignment, reads the CW function on / off information 12b to obtain the CW function. The on / off state is determined (step ST2). When the CW function is on, the F4 key is blinked, and a response by pressing the F4 key is enabled. This corresponds to the operation during the F1 call and the PK call in FIG. 9B. If there is no assignment of the CW function, and if the assignment is off even if it is assigned, the incoming call is rejected. This corresponds to the operation during the F1 call and the PK call in FIG. 9A.

  FIG. 5 shows the operation when the CW function is turned on by pressing the F4 key when all of the F1 key, F2- and PK keys are received when the CW function is set to off. It is a flowchart which shows.

  Here, when the CW function is off, if all of the F1 key, F2-, and PK key are received, the response to the PK incoming call is set to be prioritized, so if the user presses the F1 key, Pressing the F1 key is invalid (step ST11).

  Next, when the user presses the F4 key (step ST12), the CW function is turned on (step ST13). Here, when all of the F1 key, F2-, and PK keys are received when the CW function is on, it is set so that any key can respond, so that the user's press of the F1 key is effective (step ST14), a call is in progress (step ST15). The F2- and PK keys are still being received (step ST16). At this time, the lamp of the F1 key is in a lighting state indicating that a call is in progress, and the lamp of the F2 key and the lamp of the F4 key are in a blinking state indicating that a call is being received.

  FIG. 6 shows another IP phone under the SIP server 3 (in this case, IP phone 4) that is under the control of the SIP server 3 and that has the CW function turned on. FIG. 11 is a sequence diagram showing an operation when a call is rejected and a CW function is changed by long-pressing the F4 key when a call is received from the telephone 7). In addition, in this figure and FIG. 7 to be described later, description of going through the SIP server 3 is omitted.

  First, the IP telephone 7 designates the individual incoming number of the IP telephone 4 and transmits an incoming request “PK incoming-1 (INVITE)” (step S21). The IP telephone 4 transmits an incoming call response “incoming response-1 (180 TRYING)” to the IP telephone 7 (step S22).

  Next, when the user presses the F4 key for a long time, the IP telephone 4 transmits a rejection response “rejection response-1 (486 BUSY HERE)” to the IP telephone 7 (step S23), and the CW function on / off information 12b is sent. Vary off.

  After that, when there is an incoming request “PK incoming call-2 (INVITE)” specifying the individual incoming call number of the IP telephone 4 (step S24), the IP telephone 4 sends a rejection response “rejected response-2 (486 BUSY HERE)”. Transmit (step S25).

  FIG. 7 shows another IP phone under the SIP server 3 (in this case, IP phone 4) that is under the control of the SIP server 3 and that has the CW function set to OFF. FIG. 11 is a sequence diagram showing an operation when changing the CW function by pressing the F4 key when there is an incoming call from the telephone 7 to the PK key.

  First, the IP telephone 7 designates the individual incoming number of the IP telephone 4 and transmits an incoming request “PK incoming-1 (INVITE)” (step S31). The IP telephone 4 transmits a rejection response “rejection response-1 (486 BUSY HERE)” to the IP telephone 7 (step S32).

  Next, when the user presses the F4 key, the IP telephone 4 changes the CW function on / off information 12b to on. Thereafter, when there is an incoming request “PK incoming call-2 (INVITE)” designating the individual incoming call number of the IP telephone 4 (step S33), the IP telephone 4 sends an incoming call response “incoming response-2 (180 TRYING)”. (Procedure S34). As a result, the individual incoming call request moves to the F4 key.

  As described above, according to the IP telephone system of the present embodiment, the user sets the C4 function on / off setting assigned by the contractor to the F4 key that is the function key of the IP telephones 4 to 7 by the user. By pressing, it can be changed easily.

  In addition, when an incoming call is received for the PK key when the CW function is set to ON, the incoming call is rejected by pressing and holding the F4 key for a long time, and the CW function is turned off, and subsequent incoming calls are rejected. The setting can be changed so that it can be rejected.

  Furthermore, if there is an incoming call to the PK key when the CW function is set to OFF, the CW function is turned ON by pressing the F4 key, and the setting is changed so that it can respond to subsequent incoming calls. can do.
