Interoperability of presence services with wireless village and IP multimedia subsystem standards

摘要

A simple and efficient opportunity for interoperability of the presence services in line with the Wireless Village and IP Multimedia Subsystem standards is described by the method and the apparatus for recording presence attributes from the Wireless Village standard in a presence information message from the IP Multimedia Subsystem standard in a mobile communication network. At least one text character string in a presence attribute from the Wireless Village standard is recorded by a mapping unit in a note element in a presence information message from the IP Multimedia Subsystem standard, and the presence information message is transmitted to a presence server for the purpose of forwarding to further network units.
