Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides that when a subscriber registers a time-specified connection service request including a specified connection time with a specific station in a circuit-switched network, The present invention relates to a time-specified connection method in which a predetermined time-specified connection service is performed at a specified connection time based on registered connection control information.

[Conventional technology]

The wake amplifier service is known as a typical time-specified connection service to date.
This method is disclosed in Japanese Patent No. 39155 as an automatic scheduled call system. In this case, the automatic telephone exchange stores the desired call time and message notification time along with the called subscriber number by the calling subscriber's special number dial operation, and when the desired time is reached, the calling subscriber The subscriber and the called party are automatically paged to be connected, or the called party is automatically paged and connected to the message notification device.

[Problems to be Solved by the Invention] However, in the case of the above publication, the service is limited to subscribers accommodated within the own station, and therefore, when trying to provide the service to all within the network, It is necessary for all local exchanges (LS) to be equipped with functions to perform the service.

SUMMARY OF THE INVENTION An object of the present invention is to provide a time-designated connection system that can economically provide various time-designated connection services to subscribers accommodated within the network.

[Means for Solving the Problems] The above purpose is to send a call from a subscriber to a specific station in a circuit-switched network to which the network is connected using a signaling system that has a calling party number transmission function and an incomplete call reason display function. A time-specified connection service request including a specified connection time and connection control information (one or more subscriber terminal numbers, but in some cases accompanied by a message from the calling subscriber) are registered, and the connection This is achieved by performing a predetermined connection operation under connection control by the specific station based on the connection control information when the specified time is reached.

[Operation] If the connection control information registered by a subscriber in a specific station is the number of the calling subscriber terminal (the subscriber terminal that performed the registration), the connection control information registered by the subscriber at the specified station is The calling subscriber terminal is to be called. In addition, if the connection control information is the calling subscriber terminal number and the called subscriber terminal number, the calling subscriber terminal and the called subscriber terminal are called from a specific station at the specified connection time, and the specific station This is a relay connection. Furthermore, if the called subscriber terminal number is equal to or higher than the connection control information, the specific station calls the called subscriber terminal at the specified connection time, connects it to the sound source, and also transmits the connection control information. If there are one or more called subscriber terminal numbers and a message is also registered from the calling subscriber, the specific station will call those called subscriber terminals at the specified connection time and then make the call. A message from the caller is notified.

〔Example] The present invention will be explained below with reference to FIGS. 1 to 14.

First, to explain the relay system according to the present invention, FIG. 1 shows an exchange (office) 10 accommodating subscriber terminals 50 to 53 in the same circuit switching network, and an exchange (office) 1 as a specific station.
1 is a communication trunk 54, 55 and a common line signaling device 60
．． 61 shows how they are connected directly and indirectly. As shown, the exchange 10.11 has a switch 20
．． 21, call trunks 54, 55, sound sources 70, 7.1,
It is configured to include memories 40, 41, central controllers 30, 31, and common line signal devices 60, 61,
These components are logical components according to the present invention. That is, other general components of the exchange include an external storage device, a maintenance terminal, etc., but these components are not directly related to the present invention and are therefore omitted from illustration.

By the way, the circuit-switched network according to the present invention uses a signaling system (for example, CC
ITT No. 7 common line signaling system, CCITT R2
(MFC) signaling system). In the case of this signaling method, the exchange 11 that provides the service can collect the terminal number (calling ID) of the calling subscriber who requested the service from the exchange 10, and therefore, based on the terminal number, the exchange 11 It is possible to call back the subscriber terminal later. Furthermore, in the exchange 10, it is possible to add the calling ID to the inter-office signal using the existing inter-exchange communication protocol.
The calling subscriber does not need to dial his own terminal number. This is because the exchange 10 determines the originating ID from the terminal accommodation position and adds it to the interoffice signal. Furthermore, the reason (busy, non-response, etc.) when the callback of the subscriber terminal from the exchange 11 is unsuccessful is well known in existing inter-exchange communication protocols.

Now, taking the common channel signaling system as an example, first the subscriber terminal 50
To explain the case where a wake-up registration operation is performed, FIG. 2 shows an example of the signal sequence at that time (relay stage and network are not shown).

In this case, the wake-up registration special number is dialed from the calling subscriber terminal 50. As shown in FIG. 3, the registered special number is composed of wake-up service registration special numbers X, -Xi, and subsequent registration times (connection designated times) XJ-XY. Based on this, the exchange 10 transmits an address signal (IAI) including the originating ID to the exchange 11. Upon receiving this, the exchange 11 stores the originating ID and time information in the memory 4 in order to perform wake-up registration.
They are stored as a pair in the upper storage area.

As shown in FIG. 4, the storage area has addresses in units of minutes, and the size of the address space is 24×60 addresses. Time information is used as an address, and one or more caller IDs can be registered in each address. When this registration is completed, a registration completion tone is sent from the sound source 71 to the calling subscriber terminal 50. Incidentally, FIG. 5 shows an example of the sequence in the case of the R2 signaling system.

As shown in the figure, when the switch 11 recognizes the wake-up service registration special number from the switch 10, the switch 11
A sequence is entered in which the caller ID is adjusted to 0.

Eventually, when the registration time comes, the calling subscriber is called back by the exchange 11, and FIGS. 6(a) and 6(b) show the sequence at that time. As shown in FIG. 6(a), each time the time elapses in minutes, the exchange 11 refers to the storage area contents in the memory 41 using that time as an address, but the caller ID is not registered there. If the subscriber terminal is called, the subscriber terminal is called using that number as the called subscriber terminal number. That is, in this example, the subscriber terminal 50 is called back. When the subscriber terminal 50 responds to the call, the registration of the subscriber terminal 50 on the storage area is deleted, and the subscriber terminal 50 is notified by the sound source 71 that it is a wake-up call. It is. If the call fails at that time, necessary measures will be taken as shown in FIG. For example, if a subscriber terminal 50 which is in an idle state does not respond even if it is called for a certain period of time, or if it is busy, it is registered to retry in the next cycle. Additionally, if the information is illegal, such as information being renumbered, measures such as deregistration will be taken and a message to that effect will be output to the maintenance terminal.

Next, we will explain the case where the calling subscriber terminal 50 and the called subscriber terminal are relay-connected by the exchange 11 at the specified connection time. This is what is shown. The difference from that shown in FIG. 3 is that not only the special numbers X, .about.X themselves are different, but also the desired connection numbers Y1-Y are added as called subscriber terminal numbers. FIG. 8 also shows the contents that are registered in the storage area on the memory 41 when the service registration special number is dialed from the subscriber terminal 50. As shown in the figure, time information is used as an address, and each address stores one or more pairs of calling ID and called subscriber terminal number.

Eventually, at the designated connection time, the subscriber terminal 50 and the called subscriber terminal are relayed and connected through the exchange 11, and 9120a) and (b) show the sequence at that time. It is. If the subscriber terminal 50 responds to the call from the exchange 11 in the same manner as in the case of FIG. 6(a),
The subscriber terminal 50 is informed by the sound source 71 that it is a time-specific connection service, and the called subscriber terminal (in this example, the exchange 1
3) will be called. Thereafter, when each subscriber terminal 81 is called by the exchange 11 or the subscriber terminal 81 responds to the call, the subscriber terminal 50 is relay-connected to the subscriber terminal 81 via the exchange 11 at this point. If the subscriber terminal 81 does not respond to the call at that time, the time-specified connection service is re-registered by dialing a special number by hooking from the subscriber terminal 50, as shown in FIG. 9(b). It's fine if you do it like this. Note that if the subscriber terminal 50 does not respond to the call, the same measures as those explained in FIG. 6(b) are taken.

Furthermore, at the specified connection time, one or more called subscriber terminals are
10 shows the service registration special number dialed from the subscriber terminal 50 at that time.

The special number includes the terminal numbers of one or more called subscribers to be connected to the sound source 71 as terminal numbers 1, 2, 3, etc., and FIG. 41
FIG. 12 shows the contents registered in the storage area above and the sequence when the designated connection time has arrived. As in the previous case, if there is one or more called subscriber terminal numbers in the stored content whose address is the time information, those called subscriber terminals (in this example, exchange [12, 13, respectively)] Subscriber terminal 81.
82, etc.) are sequentially called by the exchange 11. When there is a response from the called subscriber terminal, the sound source 71 notifies the subscriber terminal that it is a time-specific connection service. For subscriber terminals that do not respond, necessary measures will be taken depending on the reason (see explanation regarding (1) in Figure 6).

Finally, we will explain the case where a message registered in advance by the calling subscriber is notified to one or more called subscribers at a specified connection time.In this case, the message is sent from the sound source 71 to the called subscriber The service registration special number and sequence are based on those shown in FIG. 10 and FIG. 12, respectively. Nowadays, messages must be registered in advance from calling subscriber terminals. FIG. 13 shows the contents stored in the storage area on the memory 41 at that time.
The sound source address is added to the one shown in the figure. 3. A message from the calling subscriber is registered in the sound source address inside the sound &71, but a message is received at the specified connection time. When a calling subscriber terminal is called, the message is played back from the sound source address and notified to the called subscriber terminal. FIG. 14 shows the sequence when the subscriber terminal 50 performs the service registration. If the service record special number is recognized by the exchange F#N1J, the necessary information will not be stored in the storage area of the memory 41, and will not be stored in the subscriber terminal 5.
0 is notified of the start of message registration. If this prompts the subscriber terminal 50 to send a message, the message will be registered in the area 7 indicated by the sound source address inside the sound source 7I. The registration of the message is terminated by disconnection from the subscriber terminal 50 or forced termination due to timeout.

〔Effect of the invention〕

As explained above, according to the present invention, various time-specified connection services can be economically provided to subscribers accommodated within a circuit-switched network.
