Communication system

A communication terminal equipment for performing communication control on information indicating whether or not any third party is present over a network, comprising:

• caller communication terminal presence inquiring means for making an inquiry to a receiver communication terminal about a presence state of a communicating party;
• caller communication terminal presence information receiving means for receiving presence information from said receiver communication terminal;
• caller communication terminal presence information display means for displaying said received presence information;
• receiver communication terminal presence determining means for determining said presence state of an operator of said communication terminal equipment;
• receiver communication terminal presence information generating means for generating said presence information;
• and
• receiver communication terminal presence information sending means for sending said presence information to a caller communication terminal upon reception of said inquiry.

A method implemented in a caller communication terminal to indicate presence information associated with a receiver communication terminal comprising:

• (a) transmitting an inquiry querying a receiver communication terminal a presence state associated with said receiver communication terminal;
• (b) receiving said presence state associated with said receiver communication terminal, said received presence state selected from a group of check results, comprising:
• a result of a check for active duration of a screensaver at said receiver communication terminal, a result of a check for duration of non-entry of inputs at said receiver communication terminal, a result of a pressure sensor check indicating load of an operator at said receiver communication terminal, and a result of a schedule check performed in conjunction with a schedule database, and
• (c) rendering said received presence state of said receiver communication terminal in said caller communication terminal.

A multiline reception method to indicate presence information associated with a receiver communication terminal comprising:

• (a) receiving an inquiry querying said receiver communication terminal regarding presence of an operator;
• (b) identifying presence information associated with an operator of said receiver communication terminal, said received presence information state selected from a group of checks, comprising:
• a result of a check for active duration of a screensaver at said receiver communication terminal, a result of a check for duration of non-entry of inputs at said receiver communication terminal, a result of a pressure sensor check indicating load of an operator at said receiver communication terminal, and a result of a schedule check performed in conjunction with a schedule database, and when said operator is absent,
• (c) rendering said presence information to a sub-receiver communication terminal, said sub-receiver communication terminal part of the same communication network as said receiver communication terminal.
