Abstract

PURPOSE:To reduce the charge of a public telephone network by sending plural radio call numbers stored tentatively in a voice mail system to a radio call system integrally in the charging unit time of the public telephone network. CONSTITUTION:A voice mail system 3 is provided with a storage means 33 storing tentatively voice mails with plural radio call numbers from the general subscriber 10 of a public telephone network 1 and a transmission means 32 sending the stored voice mail to the radio call system 5 in the charging unit time of the public telephone network 1 in terms of a PB signal. On the other hand, the radio call system 5 is providing with a reception means 53 receiving the PB signal of the voice mail from the voice mail system 3. Then the charging processing for one call is avoided at every radio call and the charge of the public telephone network 1 is saved.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a wireless call reception system, and in particular to a wireless call reception system via a voice mail system [Prior art] Fig. 3 shows a conventional wireless call reception system. FIG. 1 is a system configuration diagram showing an example.

In Figure 3, the voice mail system (hereinafter referred to as VMS)
In order to make a wireless call from 13, the telephone circuit (hereinafter referred to as PH
) 34 sends the calling number to the public telephone network (NW) 1 via the subscriber line 2 as a push button signal (hereinafter referred to as PB double signal or dial pulse signal (hereinafter referred to as DP signal)).

The NWI connects to the radio paging system (hereinafter referred to as RP) via trunk line 4.
S) After the call arrives at the incoming trunk circuit (hereinafter referred to as ICT) 51 of 15, the calling number is transmitted to the interoffice signal receiver (hereinafter referred to as MFR) 53. In the RPS 15, the calling number received by the MFR 53 is emitted from a radio paging equipment (hereinafter referred to as RPE) 6 as a calling radio wave for a paging receiver (not shown).

That is, a wireless call from the VMS 13 is equivalent to a wireless call from a general telephone (hereinafter referred to as 5UB) 10, and charges are processed in the NWI as one call per call.

[Problem to be solved by the invention]

In the conventional radio call reception method described above, each time a radio call is made, the call arrives at the RPS 15 via the NWI, and the NWI processes charges as one call per call at the time the radio call arrives, so the charge is proportional to the number of calls. The disadvantage is that the usage fee for the public telephone network increases.

The purpose of the present invention is to focus on the fact that the time required for a call is sufficiently short compared to the billing unit call time (3 minutes within the area) of the public telephone network, and to develop a wireless call reception method to reduce the usage fee of the public telephone network. It is about providing.

[Means to solve the problem]

The wireless call reception system of the present invention includes a voice mail system connected to the public telephone network through a subscriber line interface, and a wireless paging system connected to the public telephone network through a trunk line interface, and the voice mail system is connected to the public telephone network through a trunk line interface. storage means for temporarily storing voice mails of a plurality of wireless calling numbers from general subscribers of a telephone network; and transmitting a PB double signal to the wireless calling system by transmitting the stored voice mails within a billing unit time of the public telephone network. The radio paging system is characterized in that it includes a receiving means for receiving a PB multiplied signal of the voice mail from the voice mail system.

〔Example〕

Next, the present invention will be explained with reference to FIGS. 1 and 2.

FIG. 1 is a system configuration diagram showing an embodiment of the wireless call reception method of the present invention, and FIG. 2 is a diagram showing an example of the calling number transmission format in FIG. 1.

In FIG. 1, the same components as in the conventional example are given the same reference numerals as in FIG. 3. In other words, the system of this embodiment is
It consists of a VM 3 connected to the NWI via a subscriber line 2, an RPS 5 connected to the NWl via a trunk line 4, and an RPE 6 that emits a paging radio wave to a paging receiver (not shown) based on the call number from the RPS 5. .

The VWS 3 includes a subscriber line interface unit (hereinafter referred to as 5IF) 31 that interfaces with the subscriber line 2, a PB signal transmitter (hereinafter referred to as PBS) 32 that sends out a PB double signal, and stores voice messages of multiple call numbers to be called by radio. The RPS 5 is equipped with a voice mail device (hereinafter referred to as VME) 33, and the RPS 5 is equipped with an IC, T5, which interfaces with the trunk line 4.
1, an inter-office signal receiver (hereinafter referred to as MFR>53) that receives a multi-frequency signal of an inter-office signal (hereinafter referred to as an MP multiplied signal), a PB signal receiver (hereinafter referred to as PBR) 54 that receives a PB multiplied signal, and an ICT5.
1 to the MFR 53 and PBR 54 (hereinafter referred to as 5W) 52.

In addition, in FIG. 2, the transmission format on the trunk line 4 is n calling numbers CL G l, CL G 2 to CL
Gn are arranged in order with a delimiter code (*) in between, and an end code <#) is arranged after the call number CLGn.

Next, the operation of this embodiment will be explained.

When the caller dials the pre-assigned subscriber number of VMS 3 from SUB 10 via NWI and subscriber line 2, the call arrives at 5IF 31. When the caller then sends a voice message with a calling number (for example, CLG) to be called wirelessly, the CLG is stored in the VME 33 and the incoming communication from the caller is terminated. The VME 33 sequentially accumulates incoming calls from the next caller to the calling number to be called by radio, and waits for a certain period of time (for example, 3 minutes) or when the number of accumulated calls reaches a certain number (for example, 3 minutes).
The pending storage of these call numbers continues until the number of calls (for example, 10 calls) is reached. When the predetermined time or the predetermined number of calls is reached, the VME 33 connects the NWI via the 5IF 31 and the subscriber line 2.
When the NWI transmits the voice mail reception number assigned to the RPS 5 in advance, the NWI connects the RPS 5 and the subscriber line 2 via the trunk line 4 using a known method.

In RPS5, when the MFR53 receives the voicemail reception number via ICT51, 5W52 (solid line), 5
The W52 is switched as shown by the broken line, the RBP54 is connected, a response is returned to the NWI, and communication becomes possible. VMS
3 confirms the response of RPS5, and then sends the VM from PBS32
The call numbers held and stored in the E33 are continuously transmitted in bulk in the format shown in FIG. 2 as a PB double signal. R.P.
In S5, this format's PB double signal I Cr21
.

It is received by the PBR 54 via the NW 52 (broken line), and upon completion of the reception, communication with the VMS 3 is terminated.

After this, RPS5 receives CLG+ from PBR54,
ClO2, .about.CLGn are transmitted by radio waves via the RPE 6, and a desired called party is called by radio.

This example is not intended to limit the invention. That is, V
Although an example has been described in which multiple PB double signal call numbers are transmitted from MS3 to RPS5 and communication is terminated, a PB double signal reception completion signal may be returned from RPS5 to VMS3 before the communication with VMS3 is terminated. , or a numeric message accompanying the calling number may be transmitted and received as a PB double signal.

〔Effect of the invention〕

As explained above, the present invention enables the use of the public telephone network by collectively transmitting a plurality of wireless calling numbers temporarily held and stored in the voice mail system to the wireless calling system within the charging unit time of the public telephone network. This has the effect of reducing costs.
