Abstract: PROBLEM TO BE SOLVED: To reduce the link capacity which is required to one or more attendant terminals by making an attendant terminal other than its own one receive directly the media streams from an optional terminal and a multi-point distributor other than its own one that joins in a distributed multi-point conference system. SOLUTION: This system comprises the attendant terminals 31-33, and the terminal 31 is related with a multi-point distributor(MD) 30. The terminals 32 and 33 excluding the terminal 31 related to the MD 30 transmit directly the media streams 32', 32", 33' and 33" to other terminals. The terminal 31 is supported by the MD 30. In other words, the terminal 31 does not transmit (N-1) media streams and transmits only a single stream 31' to the MD 30. The MD 30 distributes again the stream 31' to the terminals 32 and 33 via the streams 30' and 30".

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: PROBLEM TO BE SOLVED: To obtain a method for setting up a communication session between a calling person and a called person by outputting related information or the title of a session by the output device of the called person and alarming the called person that an incoming call arrives. SOLUTION: A calling person 1 speaks a calling related statement, and the calling related statement is shown on a calling device 7. Even though a setup message 10 having calling related information 3 is subjected to path designation through a network 6, the message 10 does not reach a called device 8 yet. The information 3 is made to pass through the network 6, and an output of an alarm signal 11 including the calling related statement is shown to a called person 2 by using an output unit 5. The devices 7 and 8 are connected through the network 6, and the persons 1 and 2 are connected through communication. Telephone calling 9 is established, the status of the calling 9 becomes connection and communication through the network 6 is started.

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.

Abstract: Ein erster Computer empfängt eine oder mehrere vordefinierte Äquivalenzklassen, wobei eine vordefinierte Äquivalenzklasse einen oder mehrere im Wesentlichen äquivalente Werte umfasst. Der erste Computer empfängt mehrere Nachrichten, die zwischen einem zweiten Computer und einem dritten Computer gesendet werden, wobei jede Nachricht mindestens einen Parameter aufweist und jeder Parameter mindestens einen Entsprechungswert aufweist. Der erste Computer bestimmt, ob einer oder mehrere Parameter einen oder mehrere Entsprechungswerte aufweisen, die mit einem oder mehreren Werten einer vordefinierten Äquivalenzklasse übereinstimmen. Der erste Computer erzeugt eine oder mehrere wertbestimmte Äquivalenzklassen, wobei jede wertbestimmte Äquivalenzklasse einen oder mehrere Parameter umfasst, und wobei der eine oder jeder von den mehreren Parametern in jeder wertbestimmten Äquivalenzklasse den gleichen Entsprechungswert aufweist. Der erste Computer erzeugt einen verallgemeinerten Testfall, wobei der verallgemeinerte Testfall die mindestens eine oder die mehreren wertbestimmten Äquivalenzklassen beinhaltet.
