Abstract

PURPOSE:To improve the portable property and call operability of a receiver by employing an IC card as a portable receiver and ringing a telephone set when the IC card is connected to the telephone set and ringing the IC card if the IC card is not connected. CONSTITUTION:When a telephone set 3n at a caller side is dialed, a dial number is transmitted to an exchange 1, which calls the IC card 4m through a wireless equipment with the aid of a number from the telephone set 3n at the caller side. A person to be paged connects his IC card 4m to a nearby telephone set. If the IC card 4m is connected to the telephone set 3n at a callee side, the exchange 1 rings the telephone set 3n. Thus the portable property and call operability of a receiver can be improved.

Next, the operations of the PBXI, IC card 4n, and telephone 3n will be explained with reference to the flowcharts of FIGS. 5, 6, and 7, respectively. Steps 1-8T4F in FIG. 7 (hereinafter referred to as ST) are the operations of the telephone 3n on the calling side, FIG. 5 is the operation of the exchange 1 dialed from the telephone 3n on the calling side, and FIG. Operation of IC card 4n receiving paging call from exchange 1, ST5 to ST5 in FIG. 7
T11 indicates the operation of the telephone 3n on the called side, and will be explained approximately in this order below.

First, in the STI of FIG. 7, when the telephone 3n on the calling side is dialed (including push-button type), the process proceeds to ST2.
The dial number Ch is sent to the exchange 1. In this case, the caller can call multiple people by dialing multiple extension numbers An.

In ST21 of FIG. 5, when the PBXI CPU receives a dial from the calling side, it proceeds to 5T22, and the dialed number (
(single or plural)'ft buffer. If the dial number is not received in Sr11, directly ST23
Proceed to.

In Sr13, change the memorized dial number Ch to extension number A.
1, and if they match, proceed to 5T24; on the other hand, if Ch'<At, proceed directly to 8T27.

In Sr14, F, -0 or not, that is, the IC card reader 2 of the telephone 31. It is determined whether an IC card is connected to p, IIE Q, the process advances to 5T25, and the calling side telephone and the called side telephone A1 are connected. On the other hand, in the case of F, -t in 5T24, Sr1
Branch to 6. In this case, phone A.

Since no IC card is connected to the IC card 4m, this number (paging number) Ch is transmitted wirelessly to all the IC cards 4m.

At 5T27, it is determined whether the call between the calling party and the called party has been completed. If the call is not completed, the process advances to Sr19 and the data on the IC card that received the call charge (5T48 in Figure 6, which will be described later) is Received from the telephone of the called party (7th call described later)
8T7 in the figure) Determine whether it is LJ or not.

If no data is received in 5T28, Sr

O) and connects the called telephone and the calling telephone. In this case, the phone on the called side is STI→ST5~5
The operation T11 (described later) is performed.

On the other hand, if the PBXI makes a call by radio at 5T26 in Figure 5, all IC cards 4m are connected to S in Figure 6.
r11 The following operations are performed.

When Sr11 receives data E, that is, paging number Cht, from exchange 1, the process advances to Sr12 and stores data E (FIG. 4). In the continuation <5T43, the stored data E is compared with the own card number 13nn, and if they match, a ringing tone is generated by the buzzer. In other words, an IC card whose received data does not match its own card number will not sound a buzzer.

Person who received the call as above h6 own IC card 4m
When the IC card 4m is connected to the nearest telephone 3n, the IC card 4m operates as shown in BT45 and below in FIG. 6, and the connected telephone 3n operates as shown in 8T7 and below in FIG. in this case,
The memory flag stock in exchange 1 becomes "0".

When the IC card 4m0 CPU is connected to the nearest telephone 3n, it proceeds from Sr15 to 8T46 in FIG. 6 and stops the ringing, while the CPU of the connected telephone 3n proceeds from STI to Sr5 and Sr1 in FIG. , I
The card number Bm is requested from the C card 4m.
When the CPU of the IC card 4m receives this request, it sends its own card number 13m to the connected telephone 3n (6th
5T47, 5T4B in the figure).

The CPU of the telephone 3n to which the IC card is connected stores this card number in BmiRAM (Fig. 3) (Sr in Fig. 7).
1'), and further transmits the IC card number Bm and its own extension number Al() to the exchange 1 at Sr7 in FIG.

When the CPU of the exchange 1 receives the extension number Ak of the telephone connected to the IC card and the IC card number Bm1 as described above, the process proceeds from 5T29 to Sr10 in FIG. The 5T30 stores this received data in RAM (Figure 2).
The IC card number Bm stored in 5T31 is compared with the dial number Ch, that is, the calling number transmitted in 5T26. If the two numbers match, that is, if the called number and the received number match, the process proceeds from 5T31 to Sr12, and the calling party's telephone is connected to the telephone with extension number Al.

When the telephone of the called party receives a call, the process from Sr8 to Sr1 in Fig. 7
Proceed to STIO to generate a ring tone and go off-hook (STIO
) and becomes a talking state (STII). The calling party's telephone then proceeds from Sr1 to Sr1 in FIG. When the conversation between the two rooms ends, the switchboard 1 switches from 5T27 to 5 in FIG.
Proceed to T28, restore the line and restore the buffer (
Dial number ch > Clear all.

In the above embodiment, the present invention has been fully explained using PBXf:, but it can be used in telephone exchanges or in the city! A filling machine etc. can be used.

<Effects of the Invention> Since the phone is configured to ring when the phone is connected, and the IC card is made to ring when the phone is not connected, it is convenient to carry and easy to operate for the person making the call. becomes.
