Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for remotely writing memory for incoming call services in automatic telephone exchanges.

Conventionally, in order to rewrite the in-service memory in an incoming call service, the contents of the in-service memory were rewritten by dialing a special number from the service subscriber telephone, connecting to an in-service memory control device, etc. In the conventional method, the in-service memory is always rewritten only on the serviced subscriber's telephone, so that, for example, in a call forwarding service, a call is forwarded even if the call has not yet reached the forwarding destination. The same was true for service requests for the absentee information service.

An object of the present invention is to rewrite the memory during service from a remote location, that is, to make it possible to request a service from a telephone other than the telephone that registered the service, and to start the service from a remote location.
An object of the present invention is to provide a remote write method for a memory during incoming call service that allows smooth termination of incoming calls.

The remote writing method of the present invention includes means for receiving the serviced subscriber's telephone number, key number, and service request number from a telephone other than the serviced subscriber's telephone, and means for notifying the subscriber that the number information etc. have been received. and a means for extracting the key number from the service subscriber telephone number, and the key number received when a request is made to rewrite the in-service memory is compared with the extracted key number, and if they match, the in-service memory is rewritten. If there is a change or a discrepancy, a notification to that effect is sent through a telephone guide or the like.

Hereinafter, a conventional example and an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a diagram of a relay system of a conventional exchange that rewrites a memory during service. In FIG. 1, 1 is the called service subscriber's (SUB A) telephone, 2 is the main link of the exchange, 3 is a common control unit that performs connection control, 4 is a register for absent service that receives a service request number, and 5 is a register for absent service. A control device for a memory for absentee service, 6 a memory for an absentee guidance service, and 7 an in-service memory for incoming call transfer. Conventionally, when SUB A dials the service special number IXY, it is connected to the absent service register 4 by a known method and connected to the trunk block connector.
Via TBC, the storage location information and service type of SUB A are transferred from the common control device (MKR) 3 to the absent service register 4, and the register 4
When connected to SUB A, the register sends a service request reception ready tone to SUB A. When the subscriber SUB A next dials a number for start, stop, etc., the register 4 activates the absent service memory controller 5, and records the start or stop information and the storage location information previously received from the common control device 3. and service type information to start the in-service memory for each service. After checking whether the subscriber is being served, the service memory is rewritten,
A message indicating that the service has been completed is returned to the absent service register 4, and a completion sound is sent to SUB A from the register.
As described above, in the past, it was not possible to rewrite the in-service memory only from SUB A, that is, only from the serviced subscriber's telephone.

FIG. 2 is a relay system diagram of the exchange in the present invention,
FIG. 3 is a functional block diagram of the remote absentee service register shown in FIG. 2. In Figure 2, 8
is a telephone that does not subscribe to the service (SUB B), 9 is a talkie device, 10 is a register for remote absentee service, 11 is a number detection device, 12 is an incoming trunk, and 13 is a trunk within the own office. Note that the same numbers as in FIG. 1 indicate the same devices, and the writing method of the serviced subscriber telephone 1 is the same as the conventional method. First, when a special number (in this case, the telephone number for the remote absentee service register 10) is dialed from SUB B, connection is made to the register 10 by a known method. By being connected to the register 10, the register 10 sends out a talk tone or the like to the general subscriber telephone 8 to instruct the subscriber to dial the number of the serviced subscriber. When general subscriber SUB B dials, remote absence service register 10
, the number detection device 11 is activated to extract the key number and accommodation position information. If the subscriber is not a serviced subscriber, there is no key number, and it is possible to notify that fact. Next, general subscriber SUB B
dial the key number. This key number is received and compared with the key number from the number detection device 11. If they match, the service request number is dialed. If there is a mismatch, a tone or the like indicating the mismatch is sent to the general subscriber telephone 8. Upon receiving this service request number, the remote absentee service register 10 activates the absentee service memory controller 5 and sends out accommodation position information and service request information from the number detection device 11. The controls of the memory controller 5 for absence service, the memory 6 in service for notification of absence, and the memory 7 in service for incoming call transfer are the same as those described in FIG. 1, and will therefore be omitted.

FIG. 3 is a block circuit diagram of the remote absence service register 10 according to the present invention, where 14 is a communication path and subscriber monitoring circuit that constitutes the communication path section, and 15 is a high-sensitivity PB receiver that receives dials from general subscribers. Circuit 16 is an information control circuit that receives the output from the PB receiver and sends the information to each storage circuit.
7 is a subscriber number storage unit, 18 is a subscriber number sending unit, which is a conversion circuit for sending information to the number detection device 11, and 19 is a number detection device interface unit, which carries out startup and recovery of the number detection device and control information. 20 is a common control section of the register, a circuit that performs common control of each section; 21 is a talkie device control section that controls the transmission of various talkies to the talkie device; 22 is a timing section that controls the transmission of various talkies to the talkie device; 23 is a key number reception and storage unit; 24 is a key number verification unit that collates the key number received from the general subscriber with the key number from the number detection device; 25 is a key number receiving unit from the number detection device, 26 is a service request number reception and storage unit, 27 is an information transmission/reception control circuit for the memory controller for absent service, and 28 is an interface unit for the memory controller for absent service. This is a circuit that performs startup and recovery.

By thus receiving the subscriber number, key number, and control information at the register 10, it becomes possible to send information from the talkie device 9 to the communication path 14.

As explained above, according to the present invention, data can be written into the memory during incoming call service from other subscriber telephones other than the own telephone that has requested registration, thereby improving the service.

Claims (1)

[Claims] 1. In an automatic exchange equipped with a device for incoming call services such as an absentee announcement device and a call forwarding device, when making a service request to start or stop incoming call service, the serviced subscriber number and key number are sent from another telephone that is different from the serviced subscriber telephone. and a means for receiving the service request number, a means for notifying the subscriber that the number information etc. have been received, and a means for extracting the key number from the service subscriber telephone number in the remote incoming call service register, and When performing rewriting, when the serviced subscriber's telephone number, key number, and service request number are received from another subscriber telephone, the key number is extracted from the serviced subscriber's telephone number and extracted with the key number from the subscriber. A remote write method for memory during incoming call service is characterized in that key numbers are verified, and when a match is found, an in-service memory control device is activated to rewrite the memory contents, and when there is a mismatch, a notification is sent via a talkie or the like.
