DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a call admission distribution system,
In particular, by distributing the service of receiving international calls from hotel room phones at the International Exchange Office to announcement trunks and exchanges, it is possible to remedy call losses caused by international calls from guests. It relates to a distribution system.

[0002]

2. Description of the Related Art Generally, an international exchange office accepts an international outgoing call from a hotel room phone by checking a calling number for checking a room number and an extension telephone number of a caller.

Conventionally, when performing this type of reception at the International Exchange, the first method of connecting a call to a voice response device and sending voice guidance to confirm a room number and extension number obtained, or The second method, in which the operator performs reception work by connecting to a switching board, has been individually implemented.

As one example of the first technique, Japanese Patent Laid-Open No.
No. 137860 discloses an "automatic incoming call distribution system by voice response".

In this automatic incoming call distribution system, an incoming call arriving in an automatic private branch exchange is distributed and answered to a voice response device instead of a reception desk using an automatic incoming call distribution function, and interlocked with an external computer. Reception is automatically performed.

[0006]

In the first conventional method, when the announcement trunk or the voice response device is congested, the connection means cannot execute the connection processing, and in the second conventional method, When the operator cannot respond due to the congestion of the switching board, the operator becomes unable to respond or accept the call, and the call loss increases. However, there is a problem that the loss cannot be remedied.

[0007] In particular, in the case of an international outgoing call in which one call charge becomes expensive, occurrence of a call loss due to such internal factors of the international exchange is a serious problem.

[0008] In addition, with the introduction of intelligent terminals in each guest room of a hotel and the complicated operation of maintenance personnel and operators, the above-mentioned conventional second method is required to reduce the access to operators. There was a problem of going backwards.

SUMMARY OF THE INVENTION It is an object of the present invention to reduce the call loss generated when making an international call by using both the connection to the announcement trunk and the connection to the exchange at the international exchange, and to maintain the connection. An object of the present invention is to provide a call admission distribution system with improved easiness.

[0010]

SUMMARY OF THE INVENTION According to the present invention, a first priority connection means for connecting a call from a hotel room telephone to an announcement trunk at the international exchange, and the announcement. A second priority connecting means for connecting to a switchboard when voice guidance cannot be performed due to trunk congestion, and distributing the call acceptance service to the announcement trunk and the switchboard. A reception distribution system is obtained.

[0011] Further, in response to one command input by a maintenance person of the international exchange, provision of a service by only the first priority connection means, provision of a service by only the second priority connection means, and provision of a service by the first priority connection means. , And the provision of a service by both of the connection means having the second priority can be selected.

[0012]

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

FIG. 1 is a system block diagram of an international exchange which shows one embodiment of the call admission distribution system of the present invention.

Referring to FIG. 1, the present embodiment provides an international exchange (I) connected to each other through a national public network (NW) 2.
NTS) 3 and a private branch exchange (HTL) 1 of a hotel.

The INTS 3 includes an incoming trunk (ICT) 31 accommodated in a communication path switch (SW) 30,
32, an announcement trunk (ANT) 34,
SW3 through push button signal register (PBR) 35, board trunk (BDT) 36, and ICT 32
0 and a private branch exchange (HT) of a hotel connected to ICT 31 through NW2.
L) 1 and an exchange (ASC) 3 connected to the BDT 36
7 and a central processing unit (CPU) 38 that controls all the sequence controls in the INTS3.

Next, the operation of this embodiment will be described with reference to FIG.

FIG. 2 is a flowchart showing a procedure for processing for connecting to the announcement trunk in FIG.

When a hotel guest makes an international call from the guest room, the international call is received from the HTL 1 to the INTS 3 through the NW 2.

In the INTS 3, when the ICT 31 transmits the incoming call to the CPU 38, the CPU 38 analyzes the distribution destination of the incoming call (step S1) and checks whether the incoming call is a first priority guidance connection (S2). If it is a guidance connection (YES in S2), it is checked whether there is an empty ANT 34 (ie, whether the guidance resource is congested) (S3).

If NO in S3, that is, if the guidance resource is not congested and the ANT 34 is free, the CPU 38 controls the SW 30 to connect the link between the ICT 31 and the ANT 34, and switches the ANT 34 to the SW 30, ICT 31,
After sending guidance voice to inquire the room number and extension telephone number to the caller through NW2 and HTL1, IC
A so-called guidance process for connecting T31 to the PBR 35 is performed (S4).

When the caller dials the room number and the extension telephone number in accordance with the guidance voice, the PBR 35 receives the dial signal and transmits the dial signal to the CPU 38.
Checks whether these numbers are normal (S
5).

If YES in S5, INTS
In step 3, a process for making a call to a generally known international line is performed, and the process ends.

If NO in S2, that is, if the guidance connection is not established, the CPU 38 performs a switchboard connection process as the second priority (S6). That is, the CPU 38 controls the SW 30 to link-connect the ICT 31 and the BDT 36. As a result, the sender of the hotel is HTL1, NW2, ICT
Since the ASC 37 is connected to the ASC 37 through the SW 31, the SW 30, and the BDT 36, the operator of the ASC 37 performs an operation of accepting an outgoing international call and ends.

When the answer is YES in S3, that is, when the guidance resources are congested, and when the answer is NO in S5, that is, when the number dialed by the caller is not normal, the procedure returns to S1 and repeats the procedure up to S2 or S4.

In this embodiment, the maintenance person operates the MAT 33 to
By inputting one command to the CPU 38 through T32, the processing for the international outgoing call from the caller is performed only the connection processing of the first priority, the connection processing of the second priority only, or the processing of the second priority. It is possible to select whether to perform both the first priority and the second priority connection processing.

[0026]

As described above, the present invention provides a first priority connection means for connecting a call from a hotel room telephone to an announcement trunk at the international exchange office, and a communication means for the announcement trunk. When voice guidance cannot be implemented due to congestion, a second-priority connection means for connecting to the switching board is provided, and by distributing the international call reception service to the announcement trunk and the switching board, a call loss at the time of international calling is provided. Can be greatly reduced,
Also, there is an effect that the access load to the exchange table can be reduced.

[0027] In addition, by inputting one command by a maintenance person of the International Exchange Office, one of service provision only by guidance connection, service provision only by switching board connection, and service provision by guidance connection and switching board connection is provided. Is selectable, the security and reliability at the time of function confirmation are improved for the user, so that there is an effect that an optimal service mainly by the user can be provided.
