Patent number: 8848690Abstract: The present invention relates to a method, a system and a server for automatically discovering the common Multimedia Service Capability, and computer program. This solution avoid unnecessary use of the radio interface and is based on making use of the circuit switched network, e.g. the Intelligent network IN, as trigger to the packet switched network 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 network will send a message to each of the two mobile phones that they should notify the users e.g. by displaying an icon above a soft button. It can be that the phone displays a shared multimedia-Image icon, if this was the only commonly supported capability of both users, up to a whole range of more or less complicated SMM services.Type: GrantFiled: December 30, 2003Date of Patent: September 30, 2014Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Peter Bleckert, Mats Stille

Patent number: 8730942Abstract: A method and arrangement for enabling multimedia during an ongoing circuit-switched call between a first mobile terminal and a second terminal, wherein the first terminal uses a first access having constraints by not admitting simultaneous packet-switched and circuit-switched communication. A change of connection is detected from the first access to a second access having no such constraints by admitting simultaneous packet-switched and circuit-switched communication. A capability query is then sent to the second terminal in response to said detection. When the requested capabilities are received from the second terminal, possible multimedia applications and/or services are indicated to the user according to the received capabilities.Type: GrantFiled: November 15, 2004Date of Patent: May 20, 2014Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventor: Mats Stille

Patent number: 8443091Abstract: A method and application server for providing different services and performing service changes in a multimedia communication system. When a first client invites a second client to join a multimedia session, the server learns which media types are supported by each client, including first and second media types supported by the server. The first client then sends the server a request on a media control channel to transmit media of the first and second types. The server verifies the requested media types are supported by the second client and sends the first client a grant for the requested media types. The server receives a first media burst of the first media type from the first client and retransmits the burst to the second client, and then receives a second media burst of the second media type from the first client and retransmits the burst to the second client.Type: GrantFiled: July 12, 2012Date of Patent: May 14, 2013Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Per Synnergren, Mats Stille

Patent number: 8239547Abstract: In current multimedia communication systems using session initiation protocols such as SIP, a service change (e.g. adding a new media type to an existing multimedia conversation) entails significant delays and processor load in both clients and server. The current invention solves this by separating session signaling and media control signaling in different signaling channels (141,142) and by eliminating the need to re-establish SIP sessions for each service change. The application server (120) maintains a list of all media types supported by each multimedia client (110) involved in a multimedia conversation. Each multimedia client (110) requesting to send one or several media streams with different media types to one or several other multimedia client(s) negotiates with the application server (120) only. The inventive concept significantly reduces networks delays and speeds up the service change as perceived by the user. The invention is of interest for various multimedia conferencing applications.Type: GrantFiled: July 9, 2004Date of Patent: August 7, 2012Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Per Synnergren, Mats Stille

Patent number: 8155626Abstract: A method and apparatus for enabling communication of IP multimedia content to a called user during a circuit-switched call between a calling terminal (A) having called a primary communication unit (B1), when the call has been forwarded to a secondary communication unit (B2). The calling terminal receives a connected number during a call set-up procedure, e.g. by subscribing to a called line presentation (COLP) service. The calling terminal stores the received connected number and determines multimedia capabilities of the secondary communication unit based on the connected number. Available multimedia options can then be determined based on the multimedia capabilities of the secondary communication unit.Type: GrantFiled: January 26, 2005Date of Patent: April 10, 2012Assignee: Telefonaktiebolaget L M Ericsson (Publ)Inventor: Mats Stille

Publication number: 20110314140Abstract: A method and apparatus for handling a Session Initiation Protocol (SIP) OPTIONS capability query message in a communication network. A SIP proxy node receives a SIP OPTIONS message from a querying node. It sends the message to a plurality of devices, and receives a response from at least two of the plurality of devices. Each response includes an identity of the responding device and an indication of the capabilities of the responding device. Each received response is stored in a memory, and a reply message is generated. The reply message includes the identities and capabilities of all of the responding devices. This reply message is then sent to the querying node. This allows the querying node to receive capability information relating to all of the callee's devices rather than just the one that responds first.Type: ApplicationFiled: March 6, 2009Publication date: December 22, 2011Applicant: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Mats Stille, Håkan Österlund, Anders Ryde

Patent number: 8040874Abstract: 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.Type: GrantFiled: December 30, 2003Date of Patent: October 18, 2011Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Robert Skog, Peter Bleckert, Mats Stille
