DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system suitable for performing a simultaneous command or a conference call, and more particularly, to a system which accommodates a PHS extension telephone. It is about the method.

[0002]

BACKGROUND OF THE INVENTION The function relating to a simultaneous command in an exchange can be realized as follows. As will be described in detail later with reference to the figures, the configuration based on the method of performing the simultaneous command transmission between the stand that operates the command and the table that receives the command, and installing a special exchange separately from the exchange to perform the simultaneous command In this case, the system is configured to perform a simultaneous command transmission between the special operation telephone and the platform that operates the command.

On the other hand, a function relating to a conference call, which will also be described later with reference to the drawings, can be realized as follows. That is, a call is transmitted from the extension telephone to the corresponding extension number, and after the response, the call is transmitted to the next corresponding extension number by hooking. These operations are sequentially repeated n times (the number of extensions of the other party) for each extension required to perform conference communication, and finally, when hooking is performed, a conference telephone is established.

[0004] These will be further described with reference to FIGS.

[0005] (A) Simultaneous command method (unit related): FIG.
Shows the simultaneous command method (unit related). In this case, as shown in the figure, the system includes an exchange 10, a transmitting station 11-1 serving as a command table, and a plurality of stations 11-serving as receiving stations.
, 11-n (receiving terminals). Here, these tables 11-1 and 11-
2, 11-3,..., 11-n are fixedly installed and connected to the exchange 10.

In FIG. 9, a simultaneous command signal is transmitted (a1) from the transmitting side base 11-1 and processed by the exchange 10 (b).
1), and the tables 11-2, 11-3,..., 11-n
Call. Thus, the tables 11-2, 11-3, ...,
11-n is answered (c1). In this way, the platform 11-1 for operating the simultaneous command transmission and the platform 11 for receiving the command
, 11-3,..., 11-n, and a simultaneous command can be issued.

(B) Simultaneous command system (related to special telephones):
FIG. 10 shows another simultaneous command system (related to a special telephone). In this case, the special exchange 20 and the originating base 21-
1 and special telephones 21-2, 21-3, ..., 21-
n (reception side). Special telephones 21-2, 21-
,..., 21-n are also fixed installation (fixed telephone) connected to the special exchange 20 in the system.
It is.

In FIG. 10, a simultaneous command signal is transmitted (a2) from the transmitting base 21-1 and the special exchange 20 performs a process (b2) to call a special telephone. Thus, the incoming call is answered (c2) to the special telephones 21-2, 21-3,..., 21-n. In this way, such a system is a case where a special exchange 20 is separately installed and a simultaneous command is issued.
Stand 21-1 for operating simultaneous command transmission and special telephone 21-
2, 21-3,..., 21-n.

(C) Conference telephone system: FIG. 11 shows a conference telephone communication system. In the figure, 30 is an exchange, 31-1 to 30
-N indicates an extension telephone. Here, the extension telephones 31-1 to 30-n also have
It is a fixed installation (fixed telephone) connected to the exchange 30.
Now, assuming that a user (user) of a certain extension telephone 31-i makes a call as shown in the figure when making a conference call, a conference call state can be established by the following operation and procedure.

[0010] First, from the extension telephone 31-i on the calling side,
The extension telephone of one of a plurality of parties to be in a telephone conference, for example, the extension number of the extension telephone 31-1, is dialed (a3), and the exchange 30 performs processing (b3). call. At this point, the incoming call is answered to the extension telephone 31-1, and the telephone enters the communication state (c3). next,
The hooking operation is performed by the extension telephone 31-i, and the extension number of the next party is similarly dialed (a3), and the exchange 3
The processing (b3) is performed at 0, and the corresponding extension telephone is called. Here, the incoming call is answered to the extension telephone 31-2, and the telephone enters the communication state (c3).

In the same manner as described above, the hooking operation is performed by the extension telephone 31-i, and the extension number is dialed (a3).
Then, the exchange 30 performs the process (b3) to call the corresponding extension telephone, and the incoming call is answered to the extension telephone 31-n of the last partner, and the communication state (c3) is established. Finally, the conference telephone is established by hooking the extension telephone 31-i again.

As described above, in a conference call, a call is transmitted from the extension telephone to the corresponding extension number, and after answering, the call is transmitted to the next corresponding extension number by hooking, and is repeated a plurality of times (the number of conference parties). When hooking, it becomes a conference phone.

As described above, the simultaneous command and the conference call can be performed. However, in the method shown in FIG. 9 or FIG. 10, the fixed table (11-1, 21-1) and the table (11-
2, 11-3, ..., 11-n) or special telephone (2
1-2, 21-3,..., 21-n). In the latter case shown in FIG. 10, the special exchange 20 is constructed as a separate system, which is expensive. Become. In addition, since there is no means such as an emergency contact method when moving, the units (11-1, 11-2, 11-3,.
.., 11-n; 21-1) or special telephone (21-n)
2, 21-3,..., 21-n) determines the action range. Further, in the method shown in FIG. 11, when a conference call is performed, a call connection process is required a plurality of times, so that there is a problem that the operation is troublesome and difficult.

It is desirable that such a system be free of such disadvantages and inconveniences, that it be excellent in emergency contact and portability when moving, and that an inexpensive system configuration be possible. This can be done by an easy operation without requiring multiple times.

Therefore, when performing a simultaneous command or a conference call, use a telephone capable of responding to urgency regardless of where the user (user) is moving, and use an inexpensive telephone with commonality. With the idea that is important, the present invention seeks to embody this. Also, for the purpose of simplicity of operation, the concept that simultaneous calling can be used effectively and effectively in a conference call, and the number of outgoing connection processes can be greatly reduced, should be implemented. Is what you do.

[0024]

Embodiments of the present invention will be described below with reference to the drawings. FIGS. 1 to 8 show embodiments of the present invention using a simultaneous command and a simultaneous conference telephone communication system. Each embodiment relates to an exchange accommodating a PHS extension, and In any case, in a system having the exchange, at least a simultaneous command system for such PHS terminals is included. Hereinafter, a simultaneous command (all PHS extensions), a simultaneous command (PHS extensions by group), The simultaneous conference telephone communication method, the simultaneous conference telephone communication method (power off of the PHS extension telephones by group), and the simultaneous conference telephone communication method (during ringing of the PHS extension telephones by group) will be described in this order.

[1] Simultaneous command system (all PHS extensions
(FIGS. 1 and 2); FIG.
FIG. 2 shows an example of a system diagram, and FIG. 2 shows an example of a sequence diagram.
In FIG. 1, reference numeral 100 denotes an exchange that accommodates a PHS extension. The exchange 100 includes a plurality of PHS extension telephones 20.
And a BS (PHS base station) 30 having an antenna for these PHS extension telephones.
, 300 are connected to the exchange 100.

Here, in the illustrated example, regarding the PHS extension telephone to be accommodated in the exchange 100, among them,
The PHS extension which will be the originating PHS extension in the case of simultaneous command transmission is indicated by the reference numeral 200x, and the entire other PHS extension of the receiving end (therefore, in this case, (The originating PHS extension 200x is excluded). Also, in the figure, 200A, 200B,.
00n is a group in the case where all PHS extension telephones to be accommodated in the exchange 100 are divided into a plurality of groups in advance, that is, the groups in the case where the telephones are divided into groups A, B,. And therefore, in each group, means the entire plurality of PHS extension telephones in each group (in this case, the calling party P shown in the figure)
The HS extension telephone 200x may be a PHS extension telephone belonging to any one group in such a grouping relationship.)

The system configuration shown in FIG. 1 shows the basic configuration of the system of the present invention, and the following example also conforms to such a configuration (see FIGS. 3 and 5).

In the present system shown in FIGS. 1 and 2, after the off-hook of the PHS extension telephone 200x on the calling side, the special number +
Press the simultaneous command number dial (a), perform the simultaneous command processing (b) in the exchange 100, and then answer the incoming call to all the PHS extension telephones 200 (group A, group B,..., Group n) (c). I do.

For example, in FIG. 2, the following sequence can be used. That is, (11) [Originating side] PHS extension phone 200x: OFF hook, (1
2) exchange 100: answer, (13) PHS extension telephone 2
00x: DT, (14) PHS extension telephone 200x: Dial “special number (8) + simultaneous command number (01)” (number “801” is transmitted to exchange 100 via BS300),
(15) Exchange 100: RBT (all Ps via BS300)
HS extension phone simultaneous call), (16) [Receiving side] All PH
S extension telephone (other PHS extension telephone) 200: OFF hook (A group, B group,..., N group), (17) Exchange 100: response, connection completed, (1)
8) Talk (PHS extension phone 200x-all PHS extension phones (A group, B group, ..., n group)
200).

Here, in the present system, as shown in FIG.
It becomes a one-way command state for the S extension 200.

However, the communication state is (19) PH
S extension telephone 200x: ON hook, (20) exchange 1
00: End call, disconnection completed, (21) Exchange 100: BT,
(22) All PHS extensions (other PHS extensions) 2
00: ON hook (A group, B group, ...,
(n group), (23) Switch 100: It can be terminated by disconnecting in the order of call termination and disconnection completion.

In this way, a system for simultaneously issuing a command from a PHS extension telephone to all PHS extensions can be realized.
This can be performed between PHS extension telephones.

Therefore, in the simultaneous command method according to FIGS. 9 and 10, the communication method is performed at a fixed place between the fixed table and the table or the special telephone as described above. Constructing the switchboard as a separate system is expensive, and in any case, since there is no means such as an emergency contact method when moving, the action range is determined from the stand or the installation location of the special telephone, but in this system Without such disadvantages, when issuing a simultaneous command, the users (here, PHS extension telephones 200, 200)
This system can use a telephone (PHS terminal) capable of responding to an emergency regardless of where each user (user) of x moves, and can use inexpensive devices with commonality in general. According to this, since the PHS extension telephone is employed, emergency contact and portability at the time of movement are excellent, and an inexpensive system configuration is possible.

[2]: Simultaneous command method (PHS by group)
(Extension telephone) (Figs. 3 and 4);
A simultaneous call is made for each group (group A, B,..., N units).
Can be considered as a modification of the above method. FIG. 3 shows an example of a method according to this method, and FIG. 4 shows an example of a sequence diagram.

Since the basic system configuration, sequence, and the like are the same as those in FIGS. 1 and 2, the same reference numerals and explanations are given, and the description will be omitted. This will be described (this point is the same in the examples described later).

As shown in FIG. 2, this case can be handled for each group (A group 200A, B group 200B,..., N group 200n) composed of a plurality of PHS extension telephones. Group A is PHS01, PHS02, ..., PHS
The nth PHS extension telephone 200A-01, 200A-0
, 200A-n, and a group 200A consisting of a plurality of PHS extension telephones.
B,..., 200n also have a plurality of PHSs.
Consists of extension telephones.

Here, in the present system, the PH of the transmitting side is
After the S extension telephone 200x is hooked off, the special number + specific group dial (a ') is depressed, and the exchange 100 performs the process (b') of the simultaneous command for each group.

For example, when the group A is to be subjected to the simultaneous command, in the example of FIG. 4, the above-mentioned sequence (14) to (18) in the simultaneous command method according to [1] corresponds to the dial "special number (8) + Command to specific group (0
2. . . n) "(the number" 802 "is transmitted in the example shown in FIG. 4) → Paging for the A group 200A → A group PHS extension telephones 200A-01, 200A-02,
..., 200A-n (PHS01, PHS02, ...)
·, PHSn) OFF hook → response, connection completed → call (between PHS extension phone 200x-A group PHS extension phone 200A).

Therefore, in this case, unlike the simultaneous command method (all PHS extension telephones) according to the above [1], the simultaneous command converts the voice signal into n groups (200A to 200n) in one direction. This can be performed using the transmitting means. Therefore, in this method, for example, as shown in the above example, the A group (PHS01, PHS
HS No.,... PHSn number), when the incoming call response (c ') is made, the originating PHS extension telephone 200x receives the PHS extension telephones 200A-01, 200A of the receiving side group A.
-02,..., 200A-n are in a one-way command state. The same applies to the case of targeting other groups, which can be performed by a method according to the above. In this case, the dial number of the specific group can be received by the group by transmitting an arbitrary dial for the n group from the A group.

The disconnection of the call state in this method can be performed in accordance with the method [1]. As shown in FIG. 4, in this case, the PH of the specific group in the call state is changed.
With the ON hook of the S extension telephone (here, the A group PHS extension telephones (PHS01 to PHSn)), the call termination can be completed.

In this manner, a system for simultaneously transmitting a command from a PHS extension telephone to a specific group PHS extension telephone can be realized, and in the case of this system, the same operation and effect as in the method [1] can be obtained. . In addition, in this case, among the PHS extension telephones accommodated in the exchange 100, a part of the arbitrary PHS extension telephone group (group) is
It is possible to selectively issue a simultaneous command (simultaneous call) in group units.

[3]: Simultaneous conference telephone communication method (group
Another PHS extension telephone) (Figs. 5 and 6);
It is intended to conduct conference communication between extensions, and the simultaneous command method described in [2] above (PHS extension telephones by group)
Can be regarded as further modified examples, developed examples or applied examples, and extended examples. FIG. 5 shows an example of a method according to this method, and FIG. 6 shows an example of a sequence diagram.

The main part of this method will be described below. As shown in FIG. 5, also in this case, groups (A group 200A, B group 200B,...)
n group 200n), and uses a specific group simultaneous call. After the off-hook of the PHS extension telephone 200x on the calling side, the special number + specific group dial (a ') is pressed, and the exchange 100 The specific group simultaneous call processing (b ') is performed.

Here, in the case of the simultaneous conference telephone communication system according to the present system, conference communication is performed between PHS extension telephones by using means capable of bidirectional communication as a simultaneous conference telephone for each of n groups. So, for example,
As in the example of the method [2], the A group 20
0A PHS extension phone 200A-01, 200A-0
2,..., 200A-n are the targets of the simultaneous command, and if an attempt is made to make a telephone conference with the user of the A group PHS extension telephone, in this system, the A group (PHS01, PHS02, PHS02, ... PHSn number), when the incoming call response (c ') is made, the originating PHS extension telephone 2
00x and the receiving side group A are in a two-way communication state (see FIG. 6). The same applies to other groups B,..., Group n, and can be performed by a method according to the above. In this case, the dial number of the specific group can be received at the corresponding group by transmitting an arbitrary dial for the n group from the A group, and this point is also similar to the case of the method of [2]. It is.

Further, the disconnection of the two-way conference call state in the present method is similar to the method of the above [2], and as shown in FIG. With the ON hook of the PHS extension telephones (here, the A group PHS extension telephones (PHS01 to PHSn)) of the specific group which is set as the target and is in a talking state, the disconnection of the call can be completed.

As described above, according to this method, PH
It is possible to realize a telephone conference communication system for simultaneously transmitting a call from the S extension telephone to the specific group PHS extension telephone. Also in the case of this method, the PHS is similar to that of the method [1].
Since the extension telephone is used, emergency contact and portability at the time of movement are excellent, and an operation effect such as an inexpensive system configuration can be obtained. In addition, an operation effect similar to that of the method of [2] can be obtained. It is possible to make a conference call while playing. That is, when making a conference call, any PHS extension telephone set accommodated in the exchange 100 can be used.
A simultaneous command (paging) can be selectively performed to the HS extension telephone group (group).
It is possible to perform conference communication between the S extensions (simultaneous conference telephone communication). Therefore, in the case of the conference telephone system according to the comparative example shown in FIG. According to this method, which does not cause such a problem, and can realize the aim of simplification of operability, the use of group paging in a conference call greatly reduces the outgoing connection process.

[4]: Simultaneous conference telephone communication method (group
Another PHS extension telephone power off) (Figs. 5 and 7);
In the method according to the above [3], when simultaneous conference telephone communication is performed from a PHS extension telephone to a specific group PHS extension telephone, the incoming PHS extension telephone is to further take into account the control method when the power is turned off. It can be considered as further modified examples, developed examples, improved examples, and the like of the simultaneous conference telephone communication system (PHS extension telephone for each group). FIG. 7 shows an example of a sequence diagram as an example in the case of this method. Here, the system diagram is the same as that of the above-mentioned simultaneous conference telephone communication system [3].
And the sequence illustrated in FIG. 7 is basically the same as that in FIG.

The main part of this system will be described below. In this system, as in the case of FIG. 5, after the off-hook of the PHS extension telephone 200x on the calling side, the special number +
Press the specific group dial (a '),
To perform the general group paging process (b ').

Here, similar to the example of the group paging according to the method [3], for example, the A group 20
When the incoming signal (c ') is sent to the group 200A, the PHS extension telephone (PH
S01, PHS02, ..., PHSn-1, P
(HSn number), if there is one or more PHS extension telephones that are powered off (that is, not powered on by the user, for example), the following control is executed here. . That is, when the incoming signal is transmitted as described above, as shown in FIG. 7, if the power-off PHS extension telephone is the PHSn-th PHS extension telephone, as shown in FIG. For the PHSn number, the exchange 100 performs search and termination processing of the incoming signal. Specifically, this can be performed by performing a PHSn search in BS 300 and stopping PHSn calling when PHSn confirmation is not possible.

Therefore, in this case, the PHSn PHSn
PHS extension telephones (PHS01, PHS02,... PHSn-1) OF in group A, excluding extension telephones
When the F-hook responds and completes the connection, the originating PHS extension and the destination group A (PHS01, PHS02)
,... PHSn-1) are in a two-way communication state (see FIG. 7).

Therefore, according to the present method, a conference call state can be established under the above-mentioned control, and when the call state is disconnected, as shown in FIG. As described above, the PHS extension telephones in the A group (in this case, PHS01, PHS01,
With the PHS extension telephones PHS02,..., PHSn-1 (PHS01 to PHSn) ON hook, the end of the call can be completed.

As described above, in the present system, when simultaneous conference telephone communication is performed from a PHS extension telephone to a specific group PHS extension telephone, a control method when the incoming PHS extension telephone is turned off can be provided. The above [3]
In addition to the above-mentioned method, the same effect can be obtained. In addition, in the case of simultaneous ring telephone call from a PHS extension telephone to an arbitrary group of PHS extension telephones, the PHS with power off is controlled. When there is an extension telephone, appropriate control can be realized so that a bidirectional communication state is established between the receiving PHS extension telephone and the calling PHS extension telephone other than the PHS extension telephone.

[5]: Simultaneous conference telephone communication method (group
While calling another PHS extension phone) (Figs. 5 and 8);
In the case where the control in the above method [4] is directed to a PHS extension telephone which is powered off in the case of simultaneous conference telephone communication, the same conference telephone communication is performed from the PHS extension telephone to a specific group PHS extension telephone. In this case, it is intended to take into account the case where there is a PHS extension telephone that does not respond even during a call.

FIG. 8 shows a sequence diagram as an example in the case of this system. Note that the method diagram is also the same as that shown in FIG. 5 in the case of the simultaneous conference telephone communication method [3]. Hereinafter, the main part of this method will be described.

Also in this system, as in the case of FIG. 5, after the off-hook of the PHS extension telephone 200x on the calling side, the special number + specific group dial (a ') is pressed, and the exchange 100 calls the specific group at once. Processing (b ') is performed.

Here, as in the case of the group paging according to the method [3], for example, when an incoming signal (c ') is transmitted to the A group 200A, the PHS in the group 200A is transmitted. Extension telephones (PHS01, PHS02, ..., PHSn-
No. 1 or PHSn), a response could not be obtained even if the predetermined time was exceeded during a call (for example, the power was turned on but the user did not perform a response operation as a result for some reason). In the case where there is one or more PHS extension telephones, for example, in the case where a PHSn PHS extension telephone corresponds to such a PHS extension telephone, in the present system, the following control is executed. It shall be. That is, as shown in FIG. 8, when an incoming signal is transmitted, the exchange 100 monitors the calling PHSn for a few seconds, and if there is no response, the incoming signal is stopped (completion of disconnection). .

Thus, in this case, the PHSn number PH
PHS extension telephones (PHS01, PHS02,... PHSn-1) OF in group A excluding S extension telephones
When the F-hook responds and completes the connection, the originating PHS extension and the destination group A (PHS01, PHS02)
,... PHSn-1) are in a two-way communication state (see FIG. 8).

Therefore, in the present system, a conference call state can be established under the above control. The disconnection in the call state is the same as in FIG. 7 as shown in FIG.

As described above, according to the present system, when simultaneous conference telephone communication is performed from a PHS extension telephone to a specific group PHS extension telephone, it is possible to provide a control method in which the terminating PHS extension telephone is ringing. This allows
The same operation and effect as the method [3] can be obtained. In addition, in the case of simultaneous ring telephone communication from a PHS extension telephone to a PHS extension telephone of an arbitrary group, a response can be made even during a call. No PH
As a response to the case where there is an S extension telephone, appropriate control can be realized so that a bidirectional communication state is established between the receiving PHS extension telephone and the calling PHS extension telephone other than the PHS extension telephone.

The present invention is not limited to the above embodiment. For example, the above-mentioned methods [1] to [5] can be carried out independently, but it is of course possible to carry out them in combination. For example, the simultaneous conference telephone communication method (group Control in case of power-off of another PHS extension telephone) and the simultaneous conference telephone communication method (PHS by group) according to the above [5]
Needless to say, “control when the extension telephone is being called” can be implemented in combination.
