Method and apparatus for communicating with network from comunication terminal

A method comprising:

• communicating with a network from a communication terminal provided with a nonvolatile memory that stores identification information and a password and enabled to communicate with said network after said identification information and said password are identified, said network being provided with a storage that stores said identification information and said password, including the steps of:
• (a) receiving said identification information and said password stored in said nonvolatile memory at a start of a communication;
• (b) comparing said identification information and said password received in said step (a) with said identification information and said password stored in said storage respectively;
• (c) enabling said communication terminal to communicate with said network in response to the result of said comparison in said step (b);
• (d) receiving another password that is different from said password received in said step (a) before said communication enabled in said step (c) is ended;
• and
• (e) storing said password received in said step (d) in said storage.

A method comprising:

• communicating with a network from a communication terminal provided with a nonvolatile memory that stores identification information and a password and enabled to communicate with said network after said identification information and said password are identified, said network being provided with a storage that stores said identification information and said password, including the steps of:
• (a) sending said identification information and said password stored in said nonvolatile memory to said network at a start of a communication;
• (b) comparing said identification information and said password sent in said step (a) with said identification information and said password stored in said storage respectively;
• (c) enabling said communication terminal to communicate with said network in response to the result of said comparison in said step (b);
• (d) generating another password that is different from said password sent in said step (a) after said communication is started;
• and
• (e) storing said generated password in said nonvolatile memory;
• (f) sending said generated password to said network before said communication enabled in said step (c) is ended;
• and
• (g) storing said password sent in said step (f) in said storage.

A method comprising:

• communicating with a network from a first communication terminal provided with a first nonvolatile memory that stores identification information and a password and enabled to communicate with said network after said identification information and said password are identified and from a second communication terminal provided with a second nonvolatile memory and enabled to communicate with said network after said identification information and said password are identified, including the steps of:
• (a) storing said identification information and said password stored in said first nonvolatile memory in said second nonvolatile memory;
• (b) inhibiting the use of said first communication terminal;
• (c) sending said identification information and said password stored in said second nonvolatile memory to said network at a start of said communication;
• (d) generating another password that is different from said password sent in said step (c) after said communication is started;
• (e) storing said generated password in said second nonvolatile memory;
• and
• (f) sending said generated password to said network before said communication started in said step (c) is ended.

A method comprising:

• communicating with a network from a first communication terminal provided with a first nonvolatile memory that stores identification information and a password and enabled to communicate with said network after said identification information and said password are identified and from a second communication terminal provided with a second nonvolatile memory and enabled to communicate with said network after said identification information and said password are identified, said network being provided with a storage that stores said identification information and said password, including the steps of:
• (a) storing said identification information and said stored in said first nonvolatile memory in said second nonvolatile memory;
• (b) inhibiting the use of said first communication terminal;
• (c) sending said identification information and said password stored in said second nonvolatile memory to said network at a start of said communication;
• (d) comparing said identification information and said password sent in said step (c) with said identification information and said password stored in said storage respectively;
• (e) enabling said communication terminal to start said communication in response to the result of said comparison in said step (d);
• (f) generating another password that is different from said password sent in said step (c) after said communication is started;
• (g) storing said generated password in said second nonvolatile memory;
• and
• (h) sending said generated password to said network before said communication enabled in said step (e) is ended;
• and
• (i) storing said password sent in said step (h) in said storage.

A communication terminal enabled to communicate with a network after identification information and password are identified, said terminal including:

• a nonvolatile memory enabled to store said identification information and said password;
• a unit for generating another password that is different from said password sent at a start of said communication;
• and
• a unit for sending said identification information and said password stored in said nonvolatile memory to said network at a start of said communication, sending said generated password to said network before said started communication is ended, and storing said generated password in said nonvolatile memory.
