Method and communication system for automatically discovering the common multimedia service capability

摘要

A method, a system, a server, and a computer program product are provided for Multimedia Capability discovery of different user terminals. Unnecessary use of the radio interface is avoided based on a network storage, which is accessible without registration to find out about the calling as well as the called user's multimedia capabilities during a voice call. If there is a positive capability discovery result out of this for both users, the system sends a message to each of the user terminals that they should notify the users, e.g., by displaying an icon above a soft button. There is no need for establishing a packet switched session, which uses a lot of radio interface signalling, until the Multimedia Service capability of both subscribers and their user terminals is investigated and responded to both user terminals and their users.
