Abstract

PURPOSE:To judge a callee by a call tone, by designating different ringing patterns corresponding to extension numbers attached on an individual user, and receiving a call by a corresponding ringing pattern for an incoming call by the extension number. CONSTITUTION:An extension telephone terminal B is allocated for two common users X and Y, and the extension number of the user X is designated as 'XXX' and that of the user Y as 'YYY', and a ringing delivery program is stored in a main memory device. Thus, the different ringing patterns corresponding to the extension numbers attached on the individual user are designated, and the incoming call is received by the corresponding ringing pattern when it arrives by the extension number. In such a way, it is possible to recognize the callee out of the common users of the extension telephone terminal even from a remote place.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an extension connection method for a storage program control type exchange, and in particular, an extension connection method suitable when one extension telephone terminal is shared by multiple people. Regarding.

[Conventional technology]

When a single extension telephone terminal is jointly used by a plurality of people, when an incoming call is received at the extension telephone terminal, it is difficult to know which of the joint users is the called party. For this reason, there was the inconvenience that someone had to answer the telephone and pass it on to the person receiving the review. As a conventional technique that solves this problem, there is an extension connection system described in Japanese Patent Laid-Open Nos. 61-1197.

In this conventional technology, a display device is provided on the extension telephone terminal, and when an incoming call is received at the extension telephone number specified for each joint employee, the name of the called party is displayed on the nice play device of the corresponding extension telephone terminal. I have to.

[Problem that the invention seeks to solve]

The above-mentioned conventional technology has the disadvantage that it cannot be applied to telephone terminals that do not have a display device. In addition, even if the called party is identified by displaying the called party's name, there is no problem if the called party is close enough to the telephone to immediately recognize this display. Every time I hear a sound, I get ff-f
There is a problem in that each person must go to the place where the M phone is located in order to see the name displayed.

SUMMARY OF THE INVENTION An object of the present invention is to provide an extension connection method that can be applied to telephone terminals without a display device and that does not require the trouble of having to go to the location where the telephone is installed to confirm who the called party is. It is in.

[Means for solving problems]

The above purpose is to set different ringing patterns for each extension number assigned to each user in a storage program control exchange that accommodates extension telephone terminals that are jointly used by multiple users, and to prevent incoming calls from the extension number. This is accomplished by receiving a call using the corresponding ringing pattern.

[Effect]

When an extension telephone terminal receives a call, a ring tone sounds in a pattern corresponding to the called party, and one of the co-employees of the extension telephone terminal can immediately know who is the called party even from a remote location.

〔Example〕

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a diagram of a relay system to which an extension connection system according to an embodiment of the present invention is applied. In Fig. 1, 1 is the exchange network (NW), 2 is the central processing unit (CG), 6 is the main memory (MM), 4 is the extension telephone terminal A, 5 is the extension telephone terminal, B, and 6 are the callers. It is a register (OR). Extension telephone terminal B has two co-employees X and Y.Employee
The main storage device 3 contains an extension number-accommodation location conversion table that determines the accommodation location of the extension telephone terminal from the extension number, and an extension number that determines the ringing pattern to be sent when receiving a call from the extension number. - A ringing pattern conversion table, a number analysis program executed when extension dialing is completed, various linking pattern data, and a ringing sending program that sends out ringing using the ringing pattern data are stored.

In the extension number-accommodation location conversion table, as shown in Fig. 2, the extension number "XXX" and the extension telephone terminal B1 extension number "
Data indicating that terminal B supports internal!fMi1 talk is stored as "YYY".In the extension number-ringing pattern conversion table, as shown in FIG.
XX'', the extension number ``YYY'' of the ringing pattern 11, and the ringing pattern ■ are stored.

For example, as shown in FIG. 6, the ringing pattern data I and ■ are respectively "102102000000000"
0”.

“1212120000000000.This ringing pattern data I produces ringing in the first cycle, does nothing in the second cycle, stops ringing in the third cycle, produces ringing in the fourth cycle, and does nothing in the fifth cycle. Nothing, stop linking in the 6th period, do nothing from the 7th period to the 15th period, clear the ringing phase information to 0 in the 16th period, and repeat the operation from the first period from the 17th period. Show that.

The ringing pattern data ■ sounds a link in the first cycle, stops ringing in the second cycle, sounds a link in the third cycle, stops ringing in the fourth cycle, and stops ringing in the fifth cycle.
This indicates that the linking is sounded in the period, the ringing is stopped in the 6th period, nothing is done from the 7th period to the 15th period, the ringing phase information is cleared to 0 in the 16th period, and the same operation is repeated thereafter.

Next, the operation procedure of the extension connection system according to this embodiment will be explained according to the state transition diagram shown in FIG.

When extension telephone terminal A makes a call, the state changes from state number 1 to state number 2, and extension telephone terminal A and call register 6 are connected. Here, extension telephone terminal A is
”, the state changes from state number 2 to number analysis, reads the number analysis program shown in FIG. 5, and determines the ringing to be sent as follows.

When the number analysis program detects that an extension number has been dialed, it searches the extension number-accommodation location conversion table (FIG. 2) and determines the extension telephone terminal B on the called side. Next, from the 1fM% issue, ringing pattern conversion table (
3) to find the ringing pattern I to be sent. Then, the ringing sending program shown in FIG. 8 is read from the storage device 3, and the ringing sending program is activated using the housing position of the aX talk terminal B and the ringing pattern (2) as takeover information, and the ringing phase is set to 0 and the process ends.

The ringing sending program is activated every 200m5. In the ringing sending program, first, the ringing pattern data (<5lffl(a)) retrieved from the storage device 6 according to the ringing pattern I of the handover information is indexed by ringing phase information, and the ringing control information (6th fN(a), “0” in (b),’
1", "2").Next, if the ringing control information is "1", the phone terminal rings within m%, and if it is "2", the ringing is stopped.In the case of ringing pattern data , since the control information when indexing with phase information 0 is "1", the linking is sounded, the ringing phase information is counted up by 1, and the program ends.In the linking sending program started after 200m5, the phase information is Since the control information indexed by 1 is “0”, the phase information counter (
Cleared to 0 when the linking phase reaches 16. )
Proceed to count-up processing and end the program.

In the program execution after the next 200m5, the control information indexed by phase information 2 is "2", so extension i
! The ringing of the telephone terminal is stopped, the phase information is counted up by one, and the process ends. When such processing is performed up to phase information 16, extension telephone terminal B calls called party X using ringing pattern I shown in FIG. 7 (state number 3 in FIG. 4).

On the other hand, extension number “Y Y Y” is displayed on extension telephone terminal A.
”, the accommodation location of terminal B is searched from the extension number-accommodation location conversion table, and the ringing pattern ■ is searched from the extension number-ringing pattern conversion table.Therefore, in this case, , the recipient 11'l' person Y is called with a ringing pattern 2 (FIG. 7(b)) according to the ringing pattern data 2 shown in FIG. 6(b).

〔Effect of the invention〕
