Abstract

PURPOSE:To prevent a telephone call for service business from being charged for calls of users by registering the telephone for service business as a specific extension in advance and discriminating whether extensions are registered or not to discriminate requested originating, requested transfer, or normal call transfer when this telephone originates or transfers a call. CONSTITUTION:If an extension EXT-A as the transfer source is registered in a specific extension register table 3 and an extension EXT-B as the transfer destination is not registered, 'requested originating' is decide and an extension file address A is changed to an extension file 1 corresponding to the extension EXT B for the purpose of setting the extension EXT-B as the chrging object to perform the transfer destination extension call processing. Thus, the extension EXT-B is charged for the charge for the call of the extension EXT-A. If the extension EXT-B as the transfer source is not registered in the specific extension register table 3 and the extension EXT-B as the transfer destination is registered, 'requested transfer' is decided and a call transfer discrimination flag F is set and the extension file address A of a trunk file 2 is not changed to set the extension EXT-A as the charging object as it is.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method of registering telephone network usage charges in a private telephone exchange system, and particularly relates to a billing system for outgoing and transferred calls upon request.

[Prior Art] In general, the call network usage charges in a private telephone exchange system are calculated using the so-called charge allocation system, which is approximately registered to the extension telephone number m in the private telephone exchange system, as shown in Japanese Patent Publication No. 44-6724. It is normal that this is not done by. However, in facilities such as hotels and conference halls that open telephone facilities to users and manage and bill call charges, service telephones installed at relay stands and front desks are not used by users of guest rooms or conference rooms. "Requested call", where a call is made to the central office line upon receiving a request, and the call is transferred to the extension telephone of the requesting user after the caller answers, or a request is received from a user in a guest room or conference room who is talking to the central line, We provide services such as ``request transfer,'' which transfers calls to other applicable extensions.

[Problems to be solved by the invention] As mentioned above, in the past, there was no distinction between "requested calls" and "requested transfers," and all calls were charged as normal call transfers, so calls were also made to the above-mentioned service business telephones. There was a problem in that charges were registered and users had to pay a portion of the charges for their calls.

The object of the present invention is to provide a billing system that allows such service telephones to clearly bill users for calls without having to pay a portion of the call charges to the users.

[Means for resolving interlayer points] In the present invention, a service business telephone that accepts the above-mentioned "request call" and "request transfer" is registered in advance as a specific extension in the private telephone exchange system, and when the telephone By determining the presence or absence of the above registration at the time of calling or transferring, it is determined whether the call is a "request call", "request transfer", or "normal call transfer".
By providing a means to identify whether the call is being made, and by providing a charging means to register the call charges in the case of "request call" and "request transfer" to the extension of the user who made the request, it is clear that the user is responsible for the call charge. This is a billing method for outgoing and forwarded calls that can be made.

[Function] A service telephone such as a relay stand or a telephone at the front desk does not bear part of the user's call charges, and charges can be clearly billed to the user.

[Example] The present invention will be specifically explained below according to an example shown in the drawings.

FIG. 2 is a schematic configuration diagram of a general electronic private branch telephone switching system, where COT is a central office trunk, CPU is a central control unit including a switch processing section and a billing section, and EXT-A-EX
TC indicates an extension terminal such as a relay stand or an extension telephone. FIG. 3 is a configuration diagram of a data file held by the central control bag [CPU billing processing unit] according to the present invention, where 1 is an extension file prepared for each extension terminal, and 2 is a trunk prepared for each central office line trunk. File 3 shows a specific extension registration table in which service telephones are registered, DN is the extension number, and C is ? 5 product call charge, TN is the trunk number, A is the extension terminal connected to the central office trunk COT corresponding to trunk file 2, that is, the extension file address of the billing extension, M is the billing band index, and T is the call start time. , F represents an identification flag for call transfer processing, and 31 to 3N represent extension numbers registered as specific extensions.

FIG. 1 is a flowchart 1- for explaining the operation of an accounting processing section of a central processing unit CPU showing an embodiment of the present invention, and the operation will be explained below in comparison with FIG. 3.

(b) In the case of a normal call, when extension EXT-A makes a call to the local line and sends out the dial of the other party (step 1), the trunk file 2 corresponding to the captured central line trunk COT is found using the trunk number TN; In this trunk file 2, the extension file address A corresponding to the extension E 2) Set the call start time T. At this point, extension EXT-A becomes in a talking state.

However, if the extension EXT-A ends the call (step 4) without forwarding the call to any extension (step 3), the call charge will be calculated based on the call start time T, call end time, and billing band index M. is calculated, and the accumulated charge C for extension file 1 indicated by extension file address A, which is the billable extension, is calculated.
(Step 5).

(b) In the case of normal call transfer If extension EXT-A makes a call to the central office line, and the call is transferred to extension EXT-B while the other party is in a conversation state (step 3), call transfer identification flag F in trunk file 2 (Step 6), if the calling transfer identification flag F is absent, determine whether the transfer source extension EXT-A has HB in the specific extension registration table 3 (Step 7);
Next, it is determined whether extension EXT-B, which is the transfer destination, is registered (step 9.10). Transfer source extension EX
Both T-A and extension EXT-B, which is the forwarding destination, are registered,
If there is no i-take registration, it is judged as "normal call forwarding", and the current call charge is added to the accumulated charge C of extension file 1 of extension EXT-A, which is the billing target indicated by extension file address A of trunk file 2. Then, change the call start time T to the current time and register the transfer source extension telephone charge (Step 1).
In addition to 2), in order to set one billing target to extension EXT-B, the extension file address A is changed to extension file 1 corresponding to extensions E and XT-B, and the transfer destination extension call processing is performed (step 13).

(c) In the case of a requested call, the transfer source extension EXT-A is specified in the specific extension registration table 3.
is registered (step 7), and the forwarding destination is extension EX.
If T-B is not registered (step 10), it is determined that it is a "request transmission", and in order to charge extension EXT-B, extension file address A is changed to extension file 1 corresponding to extension EXT-B. The transfer destination extension call is then processed (step 11). As a result, extension EXT-B will bear the call charges for extension EXT-A.

(d) In the case of request transfer, the transfer source extension EXT-A is specified in the specific extension registration table 3.
If there is no registration in EXT-B (step 7), and extension EXT-B, which is the forwarding destination, is registered (step 9), it is determined that it is a "requested forwarding" and the outgoing forwarding identification flag F is set. ), the extension file address A of trunk file 2 is not changed and the billing target is set to internal HExT-A.

Next, when a call is transferred from extension EXT-B to extension EXT-C (step 3), the 1 call transfer identification flag F is reset (step 8), and it is unconditionally determined to be a normal call transfer. As a result, the call charges until extension EXT-B is transferred to extension EXT-C are added to extension EXT-A.
Also, if extension EXT-B ends the call without transferring,
The call charge for extension EXT-B is added to extension EXT-A.

[Effects of the Invention] As described above, according to the present invention, a service business telephone is registered in advance as a specified extension, and when the telephone makes a call or transfers, it is determined whether the telephone is registered or not. By making it possible to identify the nature of forwarding or normal call forwarding, the service business phone no longer bears the call charges of the user, and benefits such as being able to bill and manage IA-class call charges. There is.
