The invention relates a method, a system, a server and a computer program product for Multimedia Capability discovery of different user terminals 12,13. This solution avoid unnecessary use of the radio interface and is based on a network storage 18, 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 will send a message to each of the two user terminals 12,13 that they should notify the users e.g. by displaying an icon above a soft button. There will be 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 are investigated and responded to both user terminals and their users.
A method for automatically discovering the common Multimedia Service Capability of at least two user terminals when a voice call is initiated over a circuit switched network from a first one of the user terminals handled by a calling party to the second one of the user terminals that is handled by a called party, the first user terminal is capable of running simultaneously both a standard circuit voice call in a circuit switched network and a Shared Multimedia service (SMM) session supported by packet switched network, the other user terminal which user terminal's Multimedia Capability may be unknown for a user of the first user terminal, the method comprising the following steps of:
A system for automatically discovering the common Multimedia Service Capability of at least two user terminals when a voice call is initiated over a circuit switched network from a first one of the user terminals to the second one of the user terminals, the first user terminal is capable of running simultaneously both a standard circuit voice call in a circuit switched network and a packet switched session supported by a packet switched network, the other user terminal which user terminal's Multimedia Capability may be unknown for a user of the first user terminal, wherein the system comprises means for notifying a network storage by sending a capability request concerning the user terminals of the calling party and called party, when a trigger indication has been generated by means in the circuit switched network, means for analyzing the response comprising the requested Multimedia Service Capabilities and means for responding to said user terminals information regarding matching Multimedia Capability, if at least one matching service is found.
A system according to claim, characterized wherein the means for notifying the network storage by sending a capability request concerning the user terminals of the calling party and the called party starts when it receives an indication that a trigger event based on either Set-up_notification or Answer_notification has occured.
A server provided in a node of a system for automatically discovering the common Multimedia Service Capability of at least two user terminals when a voice call is initiated over a circuit switched network from a first one of the user terminals to the second one of the user terminals, the first user terminal is capable of running simultaneously both a standard circuit voice call in a circuit switched network and a packet switched session supported by a packet switched networks, the other user terminal (which user terminal's Multimedia Capability may be unknown for a user of the first user terminal, characterized by that wherein the server comprises means for notifying the network storage by sending a capability request concerning the user terminals of the calling party and the called party, when a trigger indication has been generated by the circuit switched network, means for analyzing the response comprising the requested Multimedia Service Capability and means for responding to said user terminals information regarding matching Multimedia Capability, if at least one matching service is found.
