Method and Device for Establishing a Subject-Related Communication link
A method and a device establish a subject-related communication link between two users in a communication network. At least the called user is equipped with a telecommunication terminal and a computer workstation suitable for electronic messages. Electronic messages are provided with subject-related identifiers when the same are transmitted from the calling user to the called user. The calling user can indicate a subject-related identifier to a communication link between the calling user and the called user in the communication network when the communication link is established. The subject-related identifier is then transmitted along with the call information and is forwarded from the communication network to the computer workstation of the called user. The subject-related identifier is evaluated in the computer workstation, and messages including the subject-related identifier are then indicated to the called user.

11 . A method for establishing a subject-related communication link between a calling subscriber and a called subscriber in a communication network, the called subscriber having a telecommunication terminal and a computer workstation suitable for electronic messages, comprising:
providing an electronic message with a subject-related identifier during a transmission from the calling subscriber to the called subscriber;
specifying the subject-related identifier at the calling subscriber during a process of establishing a communication link between the calling subscriber and the called subscriber in the communication network;
sending the subject-related identifier specified by the calling subscriber, the subject-related identifier being sent along with call information;
forwarding the subject-related identifier by the communication network to the computer workstation of the called subscriber;
evaluating the subject-related identifier at the computer workstation of the called subscriber; and
displaying electronic messages with the subject-related identifier to the called subscriber.
12 . The method as claimed in claim 11 , wherein
the electronic message has a header, and
a separate field for the subject-related identifier is introduced in the header of the electronic message.
13 . The method as claimed in claim 11 , wherein the communication network is a Public Switched Telephone Network (PSTN).
14 . The method as claimed in claim 11 , wherein the communication network is an Integrated Services Digital Network (ISDN).
15 . The method as claimed in claim 11 , wherein the communication network is a Public Land Mobile Network (PLMN).
16 . The method as claimed in claim 11 , wherein the communication network uses, for establishing the communication link between the subscribers, the Session Initiation Protocol SIP which is based on the Internet Protocol IP.
17 . The method as claimed in claim 12 , wherein the communication network is a Public Switched Telephone Network (PSTN).
18 . The method as claimed in claim 12 , wherein the communication network is an Integrated Services Digital Network (ISDN).
19 . The method as claimed in claim 12 , wherein the communication network is a Public Land Mobile Network (PLMN).
20 . The method as claimed in claim 12 , wherein the communication network uses, for establishing the communication link between the subscribers, the Session Initiation Protocol SIP which is based on the Internet Protocol IP.
21 . At least one device to establish a subject-related communication link between a calling subscriber and a called subscriber in a communication network, the called subscriber having a telecommunication terminal and a computer workstation suitable for electronic messages, comprising:
an input unit at the calling subscriber to input a subject-related identifier into an electronic message while establishing a communication link between the calling subscriber and the called subscriber;
a transmitter to transmit the subject-related identifier along with call information to the communication network;
a forwarding unit to forward the subject-related identifier from the communication network to the computer workstation of the called subscriber;
an evaluation unit to evaluate the subject-related identifier at the computer workstation of the called subscriber.
22 . The device as claimed in claim 21 , wherein
the calling subscriber has a telecommunication terminal, and
the input unit, the transmitter and the forwarding unit are integrated in the telecommunication terminals of the calling subscriber and the called subscriber.
23 . The device as claimed in claim 21 , wherein
the calling subscriber has a computer workstation, and
the telecommunication terminals are integrated in the respective computer workstations of the calling subscriber and the called subscriber.
