Abstract

A portable telephone system comprising first portable telephone terminal, second portable telephone terminal and a server for performing a management of position information of the first portable telephone terminal. The server is a relay server for position search service and registers into a password managing data base a password for allowing the second portable telephone terminal to search the position of the first portable telephone terminal in advance. The first portable telephone terminal notifies the password registered in the password managing data base to the second portable telephone terminal with a mail or the like. The second portable telephone terminal achieving the password transmits a position search request message to the server. The server checks the password indicated by the search request message, allows the position search and issues a search instructing message to the first portable telephone terminal.

Claims

1. A portable telephone system, comprising:

at least one first portable telephone terminal containing executing means for executing a service, creating means for creating a password to allow other terminals to request execution of the service to be carried out by said executing means and transmission means for transmitting the password created by said creating means;

at least one second portable telephone terminal containing reception means for receiving the password transmitted from said first portable telephone terminal, a password memory for storing the password received by said reception means, and control means for requesting said executing means of said first portable telephone terminal to execute the service by using the password stored in said password memory; and

at least one server containing a data base for registering the password created by said first portable telephone terminal, collating means for collating the password registered in said data base with the password used by said second portable telephone terminal when said second portable telephone terminal makes a service executing request to said first portable telephone terminal, and command means for commanding said first portable telephone terminal to carry out the execution of the service when it is judged in said collating means that both the passwords are coincident with each other.

2. The portable telephone system as claimed in claim 1, wherein the service is a service of searching the position at which said first portable telephone terminal itself is located, or a service of rejecting acceptance of a telephone call or mail.

3. The portable telephone system as claimed in claim 1, wherein said creating means encrypts the password created, and said reception means decodes the password encrypted.

4. The portable telephone system as claimed in claim 1, wherein said first portable telephone terminal is further equipped with a record memory for storing a record of passwords created by said creating means, and said creating means refers to the record of the passwords stored in said record memory to renew the password to a password which was not used past.

5. The portable telephone system as claimed in claim 1, wherein said first portable telephone terminal is equipped with a transmission destination memory for storing transmission destinations of the password, and said transmission means transmits the password to the transmission destination stored in said transmission destination memory.

6. The portable telephone system as claimed in claim 5, wherein the transmission destinations of the password are stored in said transmission destination memory so that each transmission destination and the name, telephone number and e-mail address thereof make a set with each other.

7. The portable telephone system as claimed in claim 6, wherein said transmission means transmits the password every mail address stored in said transmission destination memory.

8. The portable telephone system as claimed in claim 3, wherein said second portable telephone terminal stores the password received by said reception means into said password memory with no annunciation.

9. The portable telephone system as claimed in claim 1, wherein plural passwords are created by said first portable telephone terminal, and the respective passwords are renewed at different frequencies.

10. The portable telephone system as claimed in claim 1, wherein said first portable telephone terminal transmits information of forcedly-deleting a password to a portable telephone terminal to which the password has been already transmitted and rejection of the position search request is requested.
