摘要 |
A method for providing absence information in a telecommunication system comprising several subscribers, wherein the absence information is produced and captured by a first subscriber terminal. The presence information is transmitted to a switching node and stored therein. The switching node transmits the absence information to a second subscriber terminal such that the absence information is continuously available. Known absence text and station guarding services are used to produce and store absence information.
