Abstract
Abstract A method of operating an availability service in a telecommunication system interconnecting a legacy telephone system with at least one presence system, said legacy telephone system including a plurality of terminals (T 1 . . . T 10 ), at least some (T 1 ,T 2 ) of which are terminals of subscribers to said availability service, said method including: (a) continuously monitoring each subscriber terminal (T 1 ,T 2 ) 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 of 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 predetermined time period τ within said interval; and (e) making said availability signals accessible to any interconnected presence system.

Claim 4
Dependent Claim
70 words
The method of claim 1 , wherein said legacy telephone system is connected with said at least one presence system by means of a gateway, said method including (h) said gateway accepting telephone calls and receiving DTMF signals from said subscriber terminals; (i) generating said first or “high availability” signal when receiving a telephone call and a subscriber identification code in the form of DTMF signals from said subscriber terminal.
Claim 5
Dependent Claim
55 words
The method of claim 1 , wherein said legacy telephone system is connected with said at least one presence system by means of a gateway, said method including (j) said gateway accepting SMS messages from said subscriber terminals; (k) generating said first or “high availability” signal when receiving an SMS message from said subscriber terminal.
Claim 6
Dependent Claim
26 words
The method of any of claim 1 , wherein a subscribed user of said legacy telephone system defines said predetermined time period τ within said interval.
Claim 7
Independent Claim
