Description

Description: TECHNICAL FIELD The present invention relates to an electronic exchange that forms a representative group from a representative subscriber and a plurality of representative subscribers and performs representative selection from the representative group.

[Conventional technology]

As shown in FIG. 5, in the electronic exchange 11 having the representative group consisting of the representative subscriber A and the representative subscribers B, C, D, E, F, G and H, as shown in FIG. According to the table structure, the call next-order selection process was performed. That is, in the table structure of FIG. 6, the next-order selection order of the call received from the representative subscriber A's telephone number is the representative subscriber B → C.
→ D → E → F → G → H, and the next selection order received from the telephone number of the representative subscriber C is the representative subscriber E → F →
The case of B → D is shown.

The representative subscriber data table 12 stores data for calling the representative subscriber in the next-order selection order defined in the representative selection list 13 when the representative subscriber A receives a call with the telephone number while talking. Similarly, when the representative subscriber C calls the representative subscriber data table 14 with the telephone number while talking, the representative subscriber joins in the next-order selection order defined in the child selection list 15. Stores data for calling a person. The representative subscriber data table 14 also stores the representative number 16 so that each of the representatives can have its own position on the representative selection list 13, and when the representative element subscriber C is abolished. , A representative subscriber C who intends to easily abolish it from the representative selection list 13
You can delete the representative number of.

[Problems to be Solved by the Invention]

However, in such a conventional case, flexibility regarding additional registration, abolition or change of the representative subscriber is poor. For example, even if a certain representative subscriber is abolished, the subsequent representative subscriber information on the representative selection list 13 cannot be advanced. This is because if you try to move up,
You have to rewrite all the representative numbers in
This is because all the representative subscribers must be blocked during the rewriting during the rewriting period.

Therefore, when the data of a representative subscriber on the representative selection list 13 is deleted, the data position, that is, the representative number, becomes empty, and the next additionally registered representative subscriber occupies that position. There is a possibility that the representative selection list 13 is created differently from the registration order of the representative child subscribers, and the representative next-order selection is performed in an unreasonable order.

Further, for the same reason, there is a drawback that the representative subscriber cannot be added at an arbitrary position in the selection order. Further, a representative subscriber may be registered on the child selection list 15 of other representative subscribers in addition to the representative selection list, so that it is abolished or the accommodation position is changed. In addition to the representative selection list, the selection list for the representative subscribers in the representative group had to be updated. This is because each representative subscriber does not have data indicating which representative subscriber is present in the selection list of the representative subscriber, for saving memory. Therefore, if an attempt is made to make such a change, all the delegate selection lists must be unconditionally searched, resulting in a decrease in processing efficiency.

[Means for solving the problem]

The present invention is a representative subscriber registration table for registering a representative subscriber, and an individual telephone number of a plurality of representative subscribers for answering a call made by the representative subscriber's telephone number while the representative subscriber is talking. A representative subscriber registration table for registering each of the representative subscribers having the following, and a call made by the representative subscriber's telephone number while being assigned to each of the plurality of representative subscribers. A registration area for storing information for forming a representative selection list by chaining the responding representative subscribers bidirectionally from the representative subscriber registration table as a starting point in the order of high priority and low priority of the call, and the representative Responsive to a call received by the representative subscriber's telephone number while the subscriber is talking. Accepting other representative subscribers from each representative subscriber registration table as a starting point. Characterized in that is provided a plurality of links cells electronic exchange having a length of the registration area for storing information for forming a child selection list to a chain in both directions.

[Action]

In this way, the registration data of the child selection list of the representative child subscriber can be integrated and managed, and the addition, registration, abolition, or change of the representative child subscriber can be facilitated, and any representative can be placed at any position in the representative selection list. It is also possible to insert child subscribers.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

FIG. 1 shows the representative selection list 13 of the present invention, which has a bidirectional chain structure as can be seen from the drawing.
That is, when the representative subscriber A is newly registered and then the representative subscribers are newly registered in the order of B → C → D → E → F, the representative selection list 13 is configured as shown in FIG.

The representative subscriber table A is provided with a head pointer 17 and a tail pointer 18, and the representative pointer B having the highest priority among the representative subscribers is registered in the head pointer 17, while the tail pointer 18 is provided. The last representative subscriber F having the lowest priority is registered in.

Next, in the electronic exchange of the representative selection list 13 shown in FIG.
When → F → D is designated, in the present invention, the child selection list 15 is constructed as shown in FIG. That is,
Expand each link cell of E, F, and D to obtain C and E, F,
A new chain is formed with D, and this is used as the child selection list 15.

In this case, the representative subscriber table 14 has a head pointer 17 and a tail pointer similar to the representative subscriber table 12.
18 and also has a link cell number 19 corresponding to the delegate number 16.

Furthermore, when there is an instruction to additionally register the representative subscribers G and H at the end of the representative group and to insert B next to F in the selection list of C, it is shown in FIG. It becomes a data structure. That is, the representative selection list 13 forms a bidirectional chain by the link cells of each representative child subscriber, and the child selection list 15 for the representative child subscribers is also bidirectional using the expanded link cell. Form a chain. By expanding the link cell, it is possible to increase the child selection list 15 for the representative child subscribers one after another.

FIG. 4 shows the case where the selection list of H → F is designated for the representative subscriber G in addition to the data structure of FIG. In this case, the H and F link cells are expanded to form a third chain.

As described above, the present invention is the representative selection method using the variable length link cell. That is, by using the link cells of the variable length cells for bidirectional linkage, which are assigned to the representative subscribers on a one-to-one basis, the selection list registration data of the representative subscribers are integrated and managed.

〔The invention's effect〕

As described above, according to the present invention, the representative selection list and the child selection list are managed by using one variable-length link cell assigned to each representative subscriber, so that each selection list can be freely expanded or reduced. , Or can be changed. Further, it is possible to insert it at an arbitrary position in the selection list, and a new selection list can be easily created by expanding the link cell.
Since the representative subscriber has only one link cell, even if the representative subscriber is abolished or the accommodation position is changed, only the link cell needs to be processed, and useless processing such as searching the full selection list is performed. Since it can be omitted, efficiency can be expected.

Further, since the link cell has a variable length, it is only necessary to use a size according to need, and unnecessary memory is not required. On the other hand, even when a call arrives, it is possible to select the next rank at a processing speed equivalent to that of the conventional table structure type.
