Abstract

PURPOSE:To expand, reduce or revise each selection list freely by using one variable length link cell assigned to each representative slave subscriber so as to manage the selection list for representative groups. CONSTITUTION:A representative selection list 13 is constituted as a two-way chain constitution by assigning a representative selection link cell to a representative slave subscriber and a slave selection list 15 provided to representative slave subscribers is constituted as an incorporated two-way chain constitution. Thus, the registration data of a slave selection list 15 of the representative subscriber is integrally managed, the representative subscriber is easily added, registered, aborted or revised and an optional representative subscriber is inserted to an optional position in the representative selection list 13.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electronic exchange that forms a representative group from a representative subscriber and a plurality of representative sub-subscribers, and selects a representative from the representative group.

[Conventional technology]

As shown in FIG. 5, representative subscriber A and representative sub subscriber B,
In the electronic exchange l1 having a representative group consisting of C, DSESF, G, and H, call next order selection processing was performed using a table configuration as shown in FIG. That is,
The table structure in FIG. 6 shows that the next selection order for calls made using the telephone number of representative subscriber 8 is representative sub subscriber B-C-D.
-E → F → G → H, and the next selection order when the telephone number of representative sub subscriber C is called is representative sub subscriber E-+F → B
-D is shown.

The representative subscriber data table 12 stores data for calling representative sub-subscribers in the next selection order determined in the representative selection list 13 when a call is received from the telephone number of representative subscriber 8 while the representative subscriber is busy. Similarly, in the representative sub subscriber data table 14, if the representative sub subscriber C receives a call from that telephone number while the representative sub subscriber C is busy, the representative sub subscriber C will join in the next selection order determined in the sub selection list 15. Data for calling the person is stored. The representative child subscriber number 16 is also stored in the representative child subscriber data table 14, so that one's own position on the representative selection list 13 can be confirmed, and when the representative child subscriber C is abolished,
The representative number of the representative sub subscriber C to be abolished can be easily deleted from the representative selection list 13.

[Problem to be solved by the invention]

However, conventional systems of this kind lack flexibility in allowing for additional registration, abolition, or change of representative sub-subscribers. For example, even if a certain representative sub-subscriber was abolished, subsequent representative sub-subscriber information on the representative selection list 13 could not be moved up. This means that if you try to move up, the subsequent representative child subscriber data table 1
This is because it is necessary to rewrite all the representative sub-subscriber numbers within 4, and in doing so, all of those representative sub-subscribers must be blocked during the rewriting period.

Therefore, when the data of a certain representative sub-subscriber on the representative selection list 13 is deleted, the data position, that is, the representative sub-subscriber number becomes empty, and the next additionally registered representative sub-subscriber occupies that position. The representative selection list 13 was created in a different order from the registration order of the representative sub-subscribers, and there was a possibility that the next representative was selected in an unreasonable order.

Furthermore, for the same reason, there was also the drawback that a representative child subscriber could not be added to any position in the selection order. Furthermore, since a certain representative sub subscriber may be registered not only on the representative selection list but also on the child selection list 15 of other representative sub subscribers, if the representative sub subscriber is abolished or the accommodation position is changed. , not only the representative selection list but also the selection list for the representative child subscriber within the representative group had to be updated. This is because each representative child subscriber does not have data indicating which representative child subscriber's selection list the representative child subscriber is on in order to save memory. Therefore, if such a change is to be made, all representative child selection lists must be searched unconditionally, resulting in a decrease in processing efficiency.

[Means to solve the problem]

The present invention is characterized in that a link cell for representative selection is assigned to a representative sub subscriber, a representative selection list has a bidirectional chain structure, and a child selection list held by the representative sub subscriber has an integrated bidirectional chain structure. do.

[Effect]

This allows you to integrate and manage the registration data of the representative child subscriber's child selection list, and add, register, abolish, and delete the representative child subscriber.
Alternatively, it is possible to easily make changes and insert any representative child subscriber at any position in the representative selection list.

〔Example〕

Embodiments 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, and as can be seen from the figure, it has a bidirectional chain configuration.

That is, when the representative subscriber A is newly registered and the representative sub-subscribers are newly registered in the order of B-C-D-E-F, the representative selection list 13 is constructed as shown in FIG.

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

Next, the representative selection list 13 shown in FIG.
When specifying -F-D, the child selection list 15 is configured as shown in FIG. 2 in the present invention. In other words, each link cell of E and FSD is expanded, and C and E and F
, D, and form a new chain, and use this as the child selection list 15.

In this case, the representative child subscriber table 14, like the representative subscriber table 12, has a head pointer 17 and a tail pointer l8, and also has a link cell number 19 corresponding to the representative child number 16.

Furthermore, if representative sub subscriber G1H is additionally registered at the end of the representative group, and there is an instruction to insert B after F in the selection list of C, the data structure shown in Figure 3 is used. Become. That is, the representative selection list 13 forms a bidirectional chain with the ring cell of each representative sub subscriber,
Furthermore, the child selection list 15 for the representative child subscriber also uses expanded link cells to form a bidirectional chain.

By expanding the link cells, it is possible to successively increase the child selection list 15 for representative child subscribers.

FIG. 4 shows the data structure of FIG. 3 in which a selection list H-F is further designated for representative subscriber G. In this case, the link cell of H1F will be expanded to form a third chain.

As described above, the present invention is a representative selection method using variable length link cells. That is, by using link cells of variable-length cells for bidirectional linkage that are allocated one-to-one to representative sub-subscribers, selection list registration data of representative sub-subscribers is managed in an integrated manner.

〔Effect of the invention〕

As explained above, according to the present invention, the selection list in the representative group is managed using one variable-length link cell assigned to each representative sub subscriber, so each selection list can be freely enlarged, reduced, etc. Or it can be changed. In addition, it is possible to insert the item at any position in the selection list, and a new selection list can be easily created by expanding the link cell. Since a representative subscriber has only one link cell, even if the link cell is abolished or the accommodation location is changed, processing only needs to be performed for that link cell, eliminating unnecessary processing such as searching the entire selection list. Since it can be omitted, efficiency can be expected to increase.

Furthermore, since the link cell has a variable length, it is sufficient to use the size according to necessity, and unnecessary memory is not required. On the other hand, even when a call arrives, it is possible to select the next rank at the same processing speed as the conventional table structure type.
