Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention The present invention relates to a representative connection method using a personal telephone number, and more specifically, a method for connecting a plurality of terminal devices capable of receiving incoming calls to the same service subscriber. This relates to a representative connection method using a personal telephone number, which allows calls to be received by any available telephone number.

Prior Art and Problems A subscriber who can receive calls using his personal number (hereinafter referred to as a service subscriber) associates his personal number with the number of the terminal device that the service subscriber designates to receive calls, and sends the call to the switching center. After registering, incoming calls from a regular telephone to a service subscriber can be made by dialing the personal number from the regular telephone, connecting to the registered terminal device, and then calling the service subscriber. If the user specifies and registers the terminal device closest to the destination where he or she moves, it is convenient that the service subscriber can receive incoming calls no matter where he or she moves.

However, when a terminal device that a service subscriber has designated and registered is available for use by a subscriber other than this service subscriber (this state occurs when multiple service subscribers have registered the same terminal device in common) (In some cases, the original subscriber of a terminal device may always use the terminal device for both outgoing and incoming calls), the incoming traffic to the above terminal device is expected to increase. If this terminal receives multiple calls at the same time,
Only incoming calls from one originating subscriber are connected, and a busy tone is sent to other originating subscribers, causing them to abandon the connection. For this reason, when a large number of service subscribers collectively designate and register one terminal device, there is a drawback that the probability of the terminal device being busy becomes high.

OBJECTS OF THE INVENTION The present invention eliminates the drawbacks of the prior art described above, allows the same service subscriber to support a plurality of terminal devices capable of incoming calls, and
Embodiments of the Invention The following embodiments of the present invention will be described below with reference to the drawings. will be explained in detail.

FIG. 1 is a connection system diagram of an embodiment of the present invention, 1 and 2.
3 is a subscriber exchange, 4 is a relay exchange, and 5 is a memory for associating the personal number of the service subscriber with the telephone number of the telephone that designates the incoming call. 6 is a memory, 7 is a busy tone detection device, 8 is a register, 9 is a central control device, 1
0 is a telephone set, 13 is a communication path network device, 11 is a subscriber exchange, and 12 is a relay exchange.

In the conventional system, a service subscriber who is assigned a personal number, for example, sends his personal number and the telephone number of the telephone 1 to the nearest telephone 1 via the subscriber exchange 3 and the relay exchange 4. Store it in the memory 6 of the relay exchange 5 (
This operation is called registration), but after this registration, by sending the personal number assigned to this service subscriber from any telephone, a call is received on the registered telephone 1,
The service subscriber can be called and talked to.

However, in the system of the present invention, at the time of registration, the telephone number of the telephone 1 and the telephone number of another telephone 2 near the telephone 1 are simultaneously stored in the memory 6. That is, when a service subscriber dials a special number on the telephone 1, for example, a tray ν is sent via the subscriber exchange 3 and the relay exchange 4.
is set up to the relay exchange 5. The central control device 9 of the transit exchange 5 connects the register 8 to the train via the communication path network device 13, and sends out an acceptance tone from the register 8.

The service subscriber dials the registration instruction code, the personal number, the telephone number of telephone 1 and the telephone number of telephone 2, and these numbers are received by the register 8 of the direct trunk exchange 5. The central control unit 9 of the transit exchange 5 receives the above information received by the register 8, analyzes it, and when it learns that the received instruction code is a registration instruction, accesses the memory 6 and stores the received personal number. Index the memory area and record the telephone numbers of telephones 1 and 2 here.

Another method for registering the telephone numbers of telephones 1 and 2 is to store the numbers of telephones 1 and 2 in association with each other in the memory 6 of the exchange 5 in advance, and the service subscriber registers the instruction code, personal number, and telephone number. 2. Dial only the phone number of phone 1, and the exchange 5 dials the phone number of phone 1. There is also a method of extracting the telephone numbers of telephones 1 and 2 and recording the telephone numbers of telephones 1 and 2 in the areas of the memory 6 corresponding to the above-mentioned personal numbers. Furthermore, instead of dialing the number of telephone 1, it is also possible to automatically send from the exchange 3 or from a terminal using telephone 1 as a special terminal device.

When making an incoming call to a service subscriber to whom the personal number has been assigned using a personal number from a regular telephone IO, when the special number and personal number are dialed, the subscriber exchange 11. The data is received by the register 8 of the relay exchange 5 via the relay exchange ratio in the same manner as in the case of registration. The central control device 9 of the trunk exchange 5 reads the same contents of the register 8, accesses the memory 6, indexes the area of the personal number, and sends the telephone number.
When the telephone numbers of telephone 1 and telephone 2 are extracted, first, an incoming call is connected to telephone 1 using the telephone number of telephone 1 via trunk exchange 4 and subscriber exchange 3, and the train is connected to the busy tone detection device. Connect to 7. When there is a response from the telephone 1, the relay exchange 5 causes the connection 1 call to be made with the train from the telephone 10. If the telephone 1 is busy, the subscriber exchange 3 returns a busy tone. When the busy tone is detected by the busy tone detection device 7, the central control device 9 of the exchange 5 disconnects the train for the incoming call connection to the telephone 1, and sends the line to the already extracted telephone number of the telephone pA2. Make an incoming connection to 2. When a response is returned from telephone 2, connection is made to the L/-on from telephone 10.

Therefore, even if the service subscriber is unable to connect via the telephone 1 due to telephone 1 being busy, it is possible to connect via the telephone 2 using the personal number.

FIG. 2 shows an example of the configuration of the memory (6) in the case where the memory 6 is used to keep track of the busy status of the telephone set registered by the service subscriber for incoming calls, etc., without using the busy tone detection device 7. .

Figure 2 (C3 shows the configuration of areas for registering incoming telephone numbers for personal numbers; areas A, B,

; ~4Bn and Cn correspond to each other. Individual numbers are stored in each of the sub-areas Al to An. Sub-areas B, -Bn store telephone numbers to be registered first, and sub-areas C1 to cn store telephone numbers to be registered second.

FIG. 2(b) shows the structure of an area for storing the busy state of telephones registered to make incoming calls to service subscribers. -1=D1~Dp r Store telephone numbers in sub-areas D1-D, respectively, and write information on whether the phone is busy or not in corresponding sub-areas E0-Ep. put.

In this case, the service subscriber whose personal number is stored in the sub-area A1, due to the above registration, sends telephones 1 and 2 to the sub-area B 1 t CH corresponding to the sub-area A, respectively. It is assumed that the number is registered.

First, when an incoming call is made to a service subscriber using the telephone number 10 of FIG. That is, the telephone number of telephone 1 recorded in sub-area B1 corresponding to the personal number of sub-area A in FIG. 2(a) is extracted, and the telephone number of telephone 1 shown in FIG. 2(b) is extracted. The busy state display information of sub-area E1 corresponding to sub-area D1 in which the telephone number is recorded is extracted, and if the sub-area E is not busy, the content of sub-area E is changed to busy state and sent to telephone 1. Make an incoming connection.

If telephone 1 is busy, sub area C
1, extract the phone number of phone 2, and convert it to Figure 2 (
b) The stored sub-phone number of telephone 2 shown in
Extract all contents of sub-area E2 corresponding to area D2, 1·e −.

Similarly to the above, the busy state of telephone 2 is checked, and if it is not busy, the content of the sub-area E2 is set to busy, and an incoming call is connected to telephone 2.

When the call ends, the contents of the sub-area Ezh or E2, which stores the state of the telephone 1 or 2 used for the incoming call connection, are rewritten to indicate that it is not busy.

As mentioned above, if you configure and operate the memory heron, especially the second
If all the areas shown in Figure (b) are installed, there is no need for the busy sound detection device 7 in the exchange 5, and the busy state can be identified without extending the incoming train to the subscriber exchange 3. When the first registered telephone is busy, reconnection to the second registered telephone can be performed immediately, and personal number connection can be made without loss of connection delay. Note that in order to perform this method completely, registered telephones such as telephones 1 and 2 must be
The busy status of the telephones 1 and 2 must be constantly recognized by the exchange 5, and therefore information on the busy status of the telephones 1 and 2 must be transferred from the subscriber exchange 3 to the relay exchange 5 between offices. However, since the exchange 5 can grasp not all busy states but only the busy/autumn state for personal number connection, it is easy to implement this method. In this case, it is desirable to use the busy detection device 7 together.

FIG. 3 shows a connection method according to a different embodiment of the present invention. In this embodiment, information indicating the busy state of the telephone is stored in the local exchange that houses the telephone that makes the incoming call to the service subscriber, thereby eliminating the need for a busy tone detection device and replacing the telephone with the telephone. This eliminates the need to transfer information indicating the busy state of the telephone between offices.

In FIG. 3, the numbers are the same as in FIG. 1, except that 1.1 is the communication path network device of the subscriber exchange 3. Now, a subscriber exchange 3 that accommodates telephones 1 and 2 that make incoming calls to service subscribers is provided with a register S for accepting designated registration of the telephone numbers of the telephones 1 and 2, and a register S is provided in its memory 6. 2. The areas shown in FIGS. 2(a) and 2(b) are set up, and the personal number of the service subscriber, the first and second telephones 1 corresponding to the personal number, are set in the area shown in FIGS.
Register telephone number 2 and display the busy status of the telephone When making an incoming call to a service subscriber using a personal number from general telephone 10 in FIG. When dialing the long-distance or local office number and personal number of the exchange 30 accommodated, the train from the telephone 1o goes to the subscriber exchange 11, the transit exchange 12, 5.4.
It is extended to the local subscriber exchange 3 on the receiving side via the network equipment 14'f, and then connected to the register 8. The personal number of the service subscriber is then received at the register 8 and further transferred to the central control unit 9, where the telephone 1. Or 2 is called.

In this embodiment, the busy state of the telephones 1 and 2 registered for incoming calls is constantly monitored by the central control unit 9 of the exchange@3 in which the telephones 1 and 2 are housed, and information indicating the state is accurately transmitted. It can be set in the memory 9. Therefore, the busy sound detection device (7) in the embodiment of FIG. 1 is completely unnecessary.

The present invention is not limited to the above embodiments, and various modifications can be made within its technical scope.

For example, although the terminal device has been described as a telephone, the same applies even if the terminal device is a special terminal such as a data telephone and a magnetic card is inserted instead of a dial to register a personal number. In this case, there is no problem even if telephones 1 and 2 are both special terminals, or telephone 1 is a special terminal and telephone 2 is a telephone.

The number of incoming terminal devices that can be registered for one service subscriber's personal number is not limited to the two described in the above embodiment, but can be configured to register a larger number.

As described in the detailed description of the invention, a subscriber to a service that receives a call using a personal number registers the numbers of multiple terminal devices as all receiving terminals, and even if some of the terminal devices are busy, other free terminals can be used. This has the effect of improving the connection rate of personal number connections.
