Method for obtaining presence data
View Patent ↗A method for obtaining presence data for processing in a presence computer, in which a communications terminal accesses a service computer to use a service which is offered by it. The service computer identifies the occurrence of a predetermined service state which identifies the communications subscriber and sends a presence message to the presence computer, which presence message includes information about the service state that has occurred and about the communications terminal.
1. A method for obtaining presence data for processing in a presence computer, comprising:
accessing, via a communications terminal, a service computer to use a service which is offered by the service computer;
identifying, via the service computer, the occurrence of a predetermined service state which identifies the communications subscriber; sending, via the service computer, a presence message to the presence computer, which presence message includes information about the service state that has occurred and about the communications terminal; and
processing, via the presence computer, the information in the presence message to form presence data.
2. The method as claimed in claim 1 , wherein
the presence computer transmits a definition message to the service computer, which includes information about the service states to be identified by the service computer,
the service computer identifies the service states as predetermined service states, and
the service is monitored for the occurrence of the predetermined service states.
3. The method as claimed in claim 1 , wherein
the service computer identifies from a set of service states the service states as predetermined service states which result in a change in the accessibility of the communications terminal, and
the service is monitored for an occurrence of the predetermined service states.
4. The method as claimed in claim 1 , wherein the service computer reads state data which is stored in a service computer program, with the state data including information about the service states which occur during running of the service computer program on the service computer.
5. The method as claimed in claim 3 , wherein the service computer uses a signaling message to transmit information about the predetermined service states to the presence computer.
6. The method as claimed in claim 1 , wherein an occurrence of a predetermined service state is identified when the communications subscriber registers as a service user with the service computer.
7. The method as claimed in claim 1 , wherein an occurrence of a predetermined service state is identified when the communications subscriber starts a service computer program on the service computer.
8. The method as claimed in claim 1 , wherein an occurrence of a predetermined service state is identified when the communications subscriber ends a service computer program on the service computer.
9. The method as claimed in claim 1 , wherein a service formed as a value added service is accessed.
10. The method as claimed in claim 1 , wherein the service computer forms a node of a mobile radio network which is connected to the presence computer.
11. The method as claimed in claim 1 , wherein the service computer is connected via an open interface to a mobile radio network which is connected to the presence computer.
12. The method as claimed in claim 11 , wherein the open interface is formed by an OSA/Parlay Gateway.
