Abstract

PURPOSE:To improve the processing capability of a call control program by selection one available line wire originating route with an line wire route line selecting program based on a line wire originating route information list including plural sets of the line wire originating route information matched with the line wire originating service restriction condition of an outgoing terminal equipment. CONSTITUTION:A call control program 5 receives the line wire originating route information list 8 to apply function call to the line wire route line selection program 7. The line wire route line selection program 7 reads the line wire route information from the received line wire originating route information list 8 to check whether or not the line wire originating route line is available. When the line is available, the external call route line is selected and the line wire originating route line number is returned to the call control program 5 as a function return. Thus, the number of times of function calls of the line wire route information read program by the call control program is reduced and the processing capability of the call control program is enhanced.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for controlling an outside line origination in an exchange, and in particular to a method for reading outside line origination route information and a method for selecting an outside line origination route line.

[Conventional technology]

FIG. 3 is an explanatory diagram of a conventional outside line origination control method. The call control program 1 receives the destination number information and calls the external line route information reading program 2 as a function.

The outside line route information reading program 2 returns one piece of outside line originating route information corresponding to the input destination number information to the call control program 1 as a return value.

The call control program 1 uses the received outside line origination route information as input and calls the outside line origination regulation program 3 as a function.

The outside line call regulation program 3 determines whether the input outside line call route information conforms to the service regulation conditions of the calling terminal, and returns compliance/nonconformity to the call control program 1 as a return value.

If "conformity" is returned as the return value, the call control program 1 calls the external line route line selection program 4 using the external line origination route information as input; however, if the call control program 1 is nonconforming, the external line origination continues until it becomes compatible. The route information is read out and the service restriction conditions of the calling terminal are checked repeatedly.

[Problem to be solved by the invention]

In the conventional method for reading outside line origination route information described above,
Since the outside line route information reading program 2 cannot read multiple pieces of outside line calling route information at once, the outside line route information reading program 2 and the outside line calling regulation program 3 are separate, and the read outside line calling route information is If the service restriction conditions of the terminal are not met, the call control program's processing capacity will be reduced because it will have to read out the outside line call route information and check the service restriction conditions repeatedly until the service restriction conditions are met. There were drawbacks.

[Failure to solve the problem]

In order to solve such problems, the present invention reads an outside line origination route information list containing a plurality of pieces of outside line origination route information that conforms to the outside line origination service regulation conditions of the calling terminal from an outside line route information reading program, The outside line route selection program selects one of the available outside line origination routes based on the origination route information list.

[Effect]

In the outside line origination control method according to the present invention, the number of function calls of the outside line route information reading program by the call control program can be reduced.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the outside line origination control method in an exchange according to the present invention will be described below with reference to the drawings.

FIG. 1 is a detailed explanatory diagram of the present invention. In the figure, 5 is a call control program, 6 is an external route information reading program, and 7 is an external route line selection program.

FIG. 2 is an information state diagram showing an outside line originating route information list 8 which is an output of the outside line route information reading program 6. As shown in FIG.

The call control program 5 receives the destination number information and calls the external line route information reading program 6 as a function. The outside line route information reading program 6 creates an outside line origination route information list 8 that includes a plurality of pieces of outside line origination route information that corresponds to the received number information and conforms to the service regulation conditions of the originating terminal, and sends the return value to the call control program 5. Return it as.

The call control program 5 receives the outside line origination route information list 8 as input and calls the outside line route selection program 7 as a function.

The external line route line selection program 7 reads out one piece of external line originating route information from the received external line originating route information list 8, checks whether or not that external line originating route line is available, and if available, selects that external line originating route line. After selecting a route line, the external line originating route line number is returned to the call control program 5 as a return value.

If it is not available, read out the outside line calling route information and check whether it is available repeatedly until an available outside line calling route line is selected, and after selecting an available outside line calling route line, the call is made. The selected external line originating route line number is returned to the control program 1 as a return value.

〔Effect of the invention〕

As explained above, the present invention reads an outside line origination route information list including a plurality of pieces of outside line origination route information that conforms to the outside line origination service regulation conditions of a calling terminal from an outside line route information reading program,
- The number of function calls from the call control program to the external line route information reading program can be reduced without reducing the number of function calls from the call control program to the external line route information reading program by having the external line route selection program select one of the available external line origination routes based on the information list. Therefore, there is an effect that the processing capacity of the call control program can be increased.

Claims (1)

[Claims] In an exchange capable of providing an outside line origination service, an outside line origination route information list containing a plurality of pieces of outside line origination route information that meet the outside line origination service regulation conditions of the calling terminal is read out from an outside line route information reading program, and this read outside line origination route is read out. 1. An outside line origination control method in an exchange, characterized in that an outside line route selection program selects one of the available outside line origination routes based on an information list.
