Abstract

A portable telephone maintenance service system and maintenance service method for backup control of a portable telephone set, to make it possible to prevent misuse by third persons and to perform data restoration service. A maintenance service center is connected to an exchange network and by a backup control request, that includes the portable telephone number and a code number from the person who lost the portable telephone set, dialing is done from the maintenance service center to the lost portable telephone set. Memory dial data, mail address data, and other data from the memory of the portable telephone set is saved to backup memory and the data in the memory of the portable telephone set is erased. Upon a backup control request when the portable telephone set is recovered, data is downloaded from the backup memory to the memory of the portable telephone set.

Claims

1. A communication system between a portable telephone set having a memory and a general telephone set via an exchange network, comprising:

a portable telephone service system having

a maintenance service center that is accessible via said exchange network from said portable telephone set and said general telephone set, and

said maintenance service center including a backup memory and a controller, wherein a backup control request, including a code and a number of said portable telephone set that are entered by an authorized person having the code and the number of said portable telephone set, performs control to save said portable telephone set'"'"'s memory dial data, mail address data, and other input-set data in said backup memory and erase said data stored in said portable telephone set'"'"'s memory and said maintenance service center further includes a dialing unit configured to dial a number of said portable telephone set to connect with said portable telephone via the exchange network.

2. The communication system as described in claim 1 wherein, said controller of said maintenance service center has a structure in which said memory dial data, mail address data, and other input-set data saved in said backup memory is downloaded to said portable telephone set at the backup control request from the owner of the portable telephone set, wherein the authorized person includes the owner of the portable telephone set.

3. A maintenance service method comprising:

providing a maintenance service center in a system that performs communication between a portable telephone set having a memory and a general telephone set via an exchange network, said maintenance service center including a backup memory, and

receiving a backup control request, including a code and a number of said portable telephone set that are entered by an authorized person having the code and the number, of said portable telephone set wherein said portable telephone set is accessed from said maintenance service center by a dialing unit dialing a portable telephone number of said portable telephone to connect with said portable telephone set, said portable telephone set'"'"'s memory dial data, mail address data, and other input-set data is saved to said backup memory, and said data stored in said portable telephone set'"'"'s memory is erased.

4. A maintenance service method as described in claim 3 wherein upon receiving the backup control request, said maintenance service center performs dialing according to said potable telephone number, and if said portable telephone set is busy or is waiting, the memory dial data, mail address data, and other input-set data stored in said portable telephone set'"'"'s memory is saved to the backup memory of said maintenance service center with a control number added to it, said data stored in said portable telephone set'"'"'s memory is erased, and said portable telephone set'"'"'s owner is notified of said control number.

5. A maintenance service method as described in claim 3 wherein upon receiving the backup control request, including code number, portable telephone number, and control number, said maintenance service center performs dialing according to said potable telephone number, and downloads to the memory of said portable telephone set the memory dial data, mail address data, and other data saved to said backup memory.

6. A maintenance service method as described in claim 3, wherein a time period is set forth for storing said portable telephone set'"'"'s memory dial data, mail address data, and other data in said backup memory of said maintenance service center, and it is erased after elapse of said time period.

7. The maintenance service method of claim 3, wherein

the authorized person includes an owner of the portable telephone set, and wherein

the owner initiates a backup control request by entering the code and the number of said portable telephone set from another telephone set or communication device.

8. A memorizing apparatus being able to communicate with a portable telephone via base stations in a network, comprising:

a dialing unit dialing a number of said portable telephone to connect with said portable telephone via one of said base stations; and

a memory storing information transmitted by said portable telephone in response to a backup request, including a code and a number of said portable telephone that are entered by an authorized person of said portable telephone, from said memorizing apparatus.

9. The memorizing apparatus of claim 8, wherein a person initiates a backup request by entering the code and the number of said portable telephone set from another telephone set or communication device.
