Abstract

PURPOSE:To realize the economical automatic answering mobile telephone system well-managed as the entire mobile body system even when a function of an automatic answering telephone set is added to a usual talking function. CONSTITUTION:When a call comes to a mobile set from a general telephone set of a public network 1 via an exchange 2, the exchange 2 uses an allocation control section 5 to select an idle, e.g. talking channel 4-1 among talking channels 4-1 to 4-n allocated for an incoming call for the connection. The talking channel 4-1 calls a mobile set 7 through a radio equipment 6-1 and when the user is absent, the mobile set 7 outputs an absence reply signal. The talking channel 4-1 receiving a signal through the radio equipment 6-1 takes over the succeeding processing to a realization circuit of the automatic answering telephone mobile set in pairs. The talking channel 4-1 gives an end notice to the allocation control section 5 to terminate a series of operation.

Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention provides a function to record a message from the caller and play it back later when a call is received on a mobile phone such as a car phone and the user of the phone is absent. Concerning a mobile answering machine system.

0002

[Prior Art] A conventional system, as shown in the configuration diagram of FIG.
Circuit block 4- configuring k speech channels in total
1, -4-n, and 4-k, a circuit for realizing the above-mentioned answering machine function was added to each of the telephone answering machines, making it part of the function of the entire communication channel circuit block.

0003

[Problem to be solved by the invention] However, mobile phones are used far more often for making calls than for receiving calls, and even when calls are received, the number of calls that are normally received goes to answering machine. More than the number of incoming calls. That is, the percentage of operation of the answering machine function added to the normal communication channel circuit is small, and the idle time is large. This is unfavorable from a business standpoint, since the cost of the communication channel circuit with the added function becomes higher than the profit from the added function. SUMMARY OF THE INVENTION An object of the present invention is to realize an economical answering machine mobile telephone system that is financially viable as a whole mobile telephone system even when an answering machine function is added to a normal telephone call function.

0004

[Means for solving the problem] This purpose is based on the idea of making the circuit for realizing the function of an answering machine independent from the normal call channel circuit, and with reference to the principle diagram in Figure 1, the call channel circuit This is achieved by the present invention, in which the answering machine circuit and the answering machine circuit are configured to be separate from each other in terms of structure, but are operationally integrated to execute one sequence. This is achieved by the present invention, in which a means is provided for mutually coupling the answering machine circuit and the answering machine circuit. The means for this is as follows: (1) Estimate the amount of calls received during the absence based on the amount of calls expected for the entire system, determine the number n commensurate with the estimated value, and connect a total of k call channel circuits 4-1 to 4. −n pieces in k 4-1
~4n, the same number n answering machine circuits 8-1 ~8-n
are connected on a one-to-one basis, and an incoming call from a caller is connected to one of the n sets of speech channel circuits and answering machine circuits at the exchange 2. or ■ Allocating n of the total k call channel circuits 4-1 to 4-k to the allocated number n of answering machine circuits 8-1 to 8-n by the switch circuit 9 by the allocation control unit 5. Connecting. The number n of answering machine circuits to be installed is determined by an estimated value of the amount of calls received during the absence, similar to the method (2) above.

[0005]

[Operation] In the present invention, by means (2) or (2), answering machine circuits 8-1 to 8-n are installed for the number n of incoming calls of the answering machine that can be predicted from the total number k of incoming calls of the system, and the answering machine is moved. A telephone system can be realized economically.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The principle diagrams in FIGS. 1 and 2 show the configuration of an answering mobile telephone system according to embodiments of the first and second inventions of the present invention. The operation of the embodiment of the first invention shown in FIG.
When there is an incoming call to mobile unit 7 via
selects and connects to a vacant call channel 4-1 among the call channels 4-1 to 4-n allocated for incoming calls by the allocation control unit 5. Communication channel 4-1 calls mobile device 7 through radio device 6-1. The mobile device 7 outputs an absence response signal when the user is absent. The communication channel 4-1, which has received the same signal through the radio 6-1, entrusts the subsequent processing to the paired answering machine implementation circuit 8-1. The answering machine circuit 8-1
After transferring information between the public network 1 and the mobile device 7, it notifies the communication channel 4-1 of the termination. The communication channel 4-1 notifies the allocation control unit 5 of the termination and completes the series of operations. As long as there is space in the call channels 4-1 to 4-n for incoming call assignment, the added function of the answering mobile phone can be realized.

The operation of the embodiment of the second invention shown in FIG. 2 is basically the same as that of the embodiment shown in FIG. If n absence response signals are detected, the allocation control unit 5 is notified. The allocation control unit 5 assigns the same number n of answering machine circuits 8-1 to
An unoccupied circuit is selected from 8-n and connected to the corresponding speech channel circuit using a switch circuit 9. The subsequent processing is the same as in the first invention.

[0008]

[Effects of the Invention] As explained above, according to the present invention, since the configuration is equipped with as many answering machine implementation circuits as are estimated to be necessary based on the total number of incoming calls, the mobile phone system as a whole is economically viable. The effect of realizing an economical answering mobile telephone system can be obtained.
