Abstract

PURPOSE:To expand the merit of route selection, by storing previously set route selecting pattern information in a storage means provided in the system of an outgoing station and selecting the route designated by the route selecting pattern information when making a call. CONSTITUTION:Between an outgoing station 1 and a ground A, routes TGXA, TGXB, TGXC, and TGXD which are respectively managed by four different supervising authorities exist. The outgoing station 1 is provided with a memory 10 for storing route selecting patterns which make calls at previously fixed rates at every route TGXA-TGXD and a selector 11 which reads out the content of the memory 10 and selects a route in accordance with the read out route selecting pattern. The content of the route selecting pattern can be freely changed in selection rate desired from the outgoing station 1 side by using a command from an external input device. In the case of the route selecting pattern, on the other hand, a time schedule is similarly set by means of a command and each pattern is used in accordance with the time schedule.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a communication network route selection method, and particularly to a communication network route selection system in which two stations are connected by a plurality of routes each managed by two or more different administrations. This invention relates to a communication network route selection method in a communication network.

[Conventional technology]

In conventional communication networks, there is only one route between two stations managed by one administration, and the route usage fee is high, so for the convenience of subscribers, there is only one route. Even if an attempt was made to select a cheaper route and connect to the destination, the originating station could not accomplish this.

[Problem that the invention seeks to solve]

With the recent movement to open up the communication network market, it has become possible for two or more administrations to provide routes between two stations. There is a growing demand for people to be able to freely choose their own route. However, since the originating station in the conventional communication network described above cannot select an inexpensive route, it has the disadvantage that it becomes uneconomical for the host agency.

[Means for solving problems]

The communication network route selection method of the present invention is such that in a communication network in which two stations are connected by a plurality of routes managed by two or more different administrations, the originating station selects the routes in advance. A storage means for storing three route selection pattern information for making calls at a predetermined rate, and a selection means for selecting a route indicated by the route selection pattern information from the storage means at the time of making the call. There is.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the communication network route selection method of the present invention, and FIG. 2 is a diagram showing an example of the route selection pattern in FIG. 1.

In Fig. 1, the communication network is a destination A connected to a transmitting station 1,
Consisting of ground B and ground C connected to transmitting station 1 via ground A, it is connected to transmitting station 1 and it! ! There is a difference between A and 4.
Routes “l” GXA, T’ managed by two administrations respectively
GXB, TGXC, and TGXD exist.

The originating station 1 has a memory 10 that stores a route selection pattern for transmitting calls at a predetermined rate for each route TGXA to TGXD, and a system that reads the contents of the memory 1o and follows the route selection pattern. and a selector 11 for selecting the route.

The route selection pattern is determined by the selection priority, for example, the second route selection pattern.
As shown in Figure (a>, (1)), several are provided. Further, the content of the route selection pattern can be freely changed by the selection ratio desired by the transmitting station 1 by means of input commands (hereinafter referred to as commands) from an external input device. On the other hand, for the route selection pattern, a timetable (for example, time of day or day of the week) is set in advance by a command, and each pattern is used according to the timetable.

Among the route selection patterns a and b shown in Figure 2 (a> and (b>), respectively, the proportion of outgoing calls selected for each route TGXA, ~TGXD is specified by a command from an external input device. .The route selection pattern a in Fig. 2 (a>) has an outgoing call rate of 30%, 20%, and 40%, respectively, from the route TGXA with the priority rank "1" to the route TGXD with the priority rank "4". %, 10% are registered, and on the other hand, the route selection pattern b in FIG. 2(b) has the priority order [IJ, ~r4.
T (E X D, T G X C,
The percentage of outgoing calls for each route is 60% and 20%.
,io%.

It is assumed that 10% are registered. Furthermore, the destinations to which the transmitting station 1 is connected are not limited to destinations A and B shown in FIG.
A route selection pattern is prepared for each destination, and the ratio of the number of calls selected in the selection order 9 is independent for each destination and can be freely set.

In the embodiment shown in FIG.
: 00 to 14:00 and 18:00 to 2
At 4:00, route selection is performed using route selection pattern a.
Monday to Friday oo: oogara 06:00
and from 14:00 to 18:00 and on Saturdays and Sundays.
It is assumed that the setting from o:OO to 24:00 is such that route selection of route selection pattern b can be made.

Next, the operation of this embodiment will be explained.

A call made from a calling station to destination A at 17:00 on Monday is connected to destination A by automatically selecting route TGXB of route selection pattern b by the selector 11. Route TGXB of pattern b has a cheaper nighttime charge than route TGXB of route selection pattern a, which has normal telephone charges. In this way, transmitting station 1
(!l administrations can change the route selection pattern and change the selection according to the conditions of the administration providing each route.

Furthermore, by applying the communication network route selection method of the present invention to the destination C that is not directly connected to the transmitting station 1, it is possible to freely select the route. . In other words, when setting selection priority conditions between the main pipes between destination A and destination C, and connecting a call to destination C1 via destination A, it is advantageous to use route TGXA preemptively, for example. If it is proposed that the conditions can be provided, the originating station 1 may set the route selection by a command so that route TGXA can be selected preferentially.

〔Effect of the invention〕

As explained above, the present invention stores route selection pattern information set in advance in the storage means provided in the system of the originating station, and when making a call, the route designated by the route selection pattern information is selected. By selecting
This has the effect of expanding the benefits of route selection for the originating station's administration.
