Abstract: PROBLEM TO BE SOLVED: To provide a method for giving the instruction of the availability in an existing telephone system to the users of presence services connected to each other, e.g. the Internet presence systems. SOLUTION: This method/system includes a step to monitor continuously the subscriber terminals when every subscriber terminal changes from a call presence state to a call absence state (a), a step to produce a 1st signal when the subscriber terminal changes from the call presence state to the call absence state (b), a step to monitor a period covering from the start of the 1st signal (c), a step to produce a 2nd signal when a prescribed period τ passes in the period (d) and a step to enable both 1st and 2nd signals to access the presence systems which are connected to each other (e).

Abstract: A method of operating an availability service in a telecommunication system (1) interconnecting a legacy telephone system (10) with at least one presence system (11), said legacy telephone system including a plurality of terminals (T,...T10), at least some (T1,T2) of which are terminals of subscribers to said availability service, said method including: (a) continuously monitoring each subscriber terminal (T1,T2) for a change of a call status of said subscriber terminal from the presence of a call to the absence of a call; (b) generating a first or "high availability" signal when said call status o f said subscriber terminal changes from said presence of a call into said absence of a call; (c) monitoring an interval of time beginning with said first signal; (d) generating a second or "availability unknown" signal after a predetermin ed time period ~ within said interval; and (e) making said availability signals accessible to any interconnected presen ce system.
