Abstract

PURPOSE:To terminate only the call having the degree of emergency exceeding priority instructed by a callee to a terminal concerning the exchange to perform incoming call control service with priority. CONSTITUTION:This exchange is provided with a first table 2 to store a call origination priority 1 set corresponding to the request level of a caller and an incoming call priority 2a set so that priority contents can become the same with the call origination priority 1, priority confirming means 3 for confirming whether an incoming call is providing with the incoming call priority 2a or not by referring to the first table 2, terminal call terminating means 4 for terminating the incoming call to the incoming call destination terminal when the call origination priority 1 is higher than the incoming call priority 2a, an incoming call refusing means 5 for the caller to refuse the incoming call to the caller when the call origination priority 1 is less than the incoming call priority 2a, and priority registering means 6 to register the incoming call priority 2a on the first table 2a and each time a call is terminated, the call origination priority 1 is compared with the incoming call priority 2a.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an exchange which provides an incoming call control service with priority.

[0002]

2. Description of the Related Art A conventional private branch exchange is configured to receive an incoming call unconditionally when a terminal is idle.

[0003]

Therefore, in the prior art, even during an important meeting or when the user is very busy, a call is made to the receiving terminal regardless of the urgency of the called party,
There is a problem that the called party can forcibly interrupt what it was doing.

An object of the present invention is to make only a call having an urgency higher than the priority designated by the callee be received by the terminal.

[0005]

In order to achieve the above object, as shown in FIG. 1, a transmission priority of 1 set in accordance with a request level of a caller and a caller terminal registered in advance by a callee terminal, and A first table 2 that stores an incoming call priority 2a that is set to have the same priority content as the outgoing call priority 1 and an incoming call is referred to by the incoming call priority 2a by referring to the first table 2. Priority confirmation means 3 for confirming whether or not
When the outgoing call priority 1 is equal to or higher than the incoming call priority 2a, the terminal receiving means 4 for receiving the incoming call to the destination terminal, and when the outgoing call priority 1 is less than the incoming call priority 2a, the caller rejects the incoming call. And a priority registration means 6 for registering the reception priority (2a) in the first table 2,
Each time there is an incoming call, the priority comparison between the outgoing call priority 1 and the incoming call priority 2a is executed, and the incoming call service with priority is performed.

[0006]

According to the present invention, as shown in FIG.
Check whether the calling priority 1 requested by the caller is equal to or higher than the incoming priority 2a stored in the first table 2,
Calls with a call priority of less than 2a are prevented from being received by the call receiving terminal by the call rejecting means 5.

Therefore, by setting the incoming call priority 2a to a high value, it becomes possible to select only incoming calls with a high degree of urgency and receive them.

[0008]

Embodiments of the present invention will be described below with reference to FIGS. FIG. 2 is a diagram showing the configuration of the first embodiment of the service of the present invention, and FIG. 3 is a diagram showing the configuration of the second embodiment of the service of the present invention. FIG. 4 is a diagram showing a processing flow of the service of the present invention.

In FIGS. 2 and 3, 10 is a private branch exchange that forms a communication path, 11 is a terminal for making a call, 12 is a terminal for receiving a call, and 13 is an announcement device for sending a message of the caller. is there.

Reference numeral 20 is a first table provided in the private branch exchange 10. The first table 20 has an extension number of the terminal 12 for receiving a call.
Stores incoming call priority 20b that is set or extracted in 20a. Similarly, 21 is a second table provided in the private branch exchange 10, and the second table 21 stores the transmission priority 21b extracted by the transmission special number 21a with priority of the transmission terminal 11.

In FIG. 4, S ** (for example, S1
0) indicates a step in the process. Further, the transmission priority 21b is, for example, the first priority is from a manager to a subordinate, the second priority is an interruption to a conference person, ...
・ The lowest level may be determined as if the connection is empty.
Similarly, the incoming call priority 20b is determined.

2A-1 and 2A-2 and FIG.
(A) shows the operation of the priority registration means 6, dialing the incoming call priority registration special number + the incoming call priority from the terminal 12 for incoming call, and setting the incoming call priority 20b in the first table 20 for registration. It is a figure of time.

In this case, when the terminal 12 dials the incoming call priority registration special number + incoming call priority and the processing is started (S10), the first table 20 is set to the extension number of the terminal 12.
After indexing at 20a and setting the incoming call priority 20b at the corresponding position (S11), the process is ended (S12).

2B-1 and 2B-2 and FIG.
(B) shows the operation of the priority confirmation means 3, and after dialing the calling special number 21a with priority from the calling terminal 11,
FIG. 7 is a diagram showing that the extension number 20a of the terminal 12 is dialed to make a call with a call priority 21b to the terminal 12.

In this case, when the terminal 11 dials the calling special number with priority + extension number of the terminal 12 to start the process (S20), the private branch exchange 10 first gives the second table 21 priority to the terminal 11. The transmission priority number 21a with a degree is indexed, and the transmission priority 21b corresponding to the particular number is obtained (S21).

Next, the first table 20 in which the incoming call priority 20b is registered in advance by the extension number 20a of the terminal 12 is indexed, and the incoming call priority 20b is extracted from the corresponding position (S22).
Then, the outgoing call priority 21b is compared with the incoming call priority 20b of the first table 20 corresponding to the extension number 20a of the terminal 12 (S23).

Further, steps S24 and S in FIGS.
25 is a diagram showing the terminal incoming call means 4 and the incoming call rejection means 5. First, FIG. 3 (A) and FIG. 4 (B) (S24)
Is an example when the transmission priority 21b is higher than or equal to the reception priority 20b. At this time, the private branch exchange 10 makes the ringer ring while the terminal 12 is ringing (S24).
Make 12 calls.

Next, FIG. 3B and FIG. 4B.
(S25) is a diagram when the transmission priority 21b is lower than the reception priority 20b. At this time, the private branch exchange 10 determines that a message is being sent between the terminal 12 and the terminal 11, connects the one-way call path from the announcement device 13 to the terminal 11, and sends a message from the announcement device 13 to the effect that "the current call cannot be made". Send to 11 to have the incoming call rejection message heard.

[0019]

As is apparent from the above description, according to the present invention, by setting the incoming call priority according to the busyness of the called party, only the calls having the urgency or higher according to the busyness are selected. Therefore, it is possible to save the trouble of declining the call after the response and prevent the work efficiency from being lowered by frequently interrupting the work.
