20080304438 | Method and Apparatus for Multimedia Communication - 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 (B | 12-11-2008 |
20090010247 | Method and Arrangement for Enabling a Multimedia Communication Session - 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. | 01-08-2009 |
20100110978 | IMS Device Reconfiguration - A method and arrangement in a telecommunication system for facilitating communications between a first terminal A configured to use a first session model and a second terminal B configured to use a second session model for media transportation. The first terminal A initiates a service capability check and in response, receives capability features of the second terminal B. Upon determining that the second terminal B uses the second session model, the first terminal A is reconfigured to use the second session model. | 05-06-2010 |
20110004518 | METHOD AND USER DEVICE FOR HANDLING MOBILE ADVERTISING - Personalized advertisements may be provided from a service node to a user, parallel to executing a request from the user device. At the service node, advertisement information may be selected, according to predefined advertisement rules and the applications which are available at the user device, and attached to a response message, sent to the user device in response to the received request. At the user device, the advertisement information is retrieved, structured and stored. A change of state of an application of the user device will initiate an interrogation of the advertisement information, which will result in performing a presentation of an advertisement on the user information, in case such instructions exists. An advertising method, a user device and a service node adapted to execute the suggested method are described. | 01-06-2011 |
20110134913 | Auxiliary SIP Services - The invention includes a method of providing media data of a SIP-based Auxiliary Service from an Auxiliary Application Server, AS, to a recipient peer of an established communication exchange between peers. The method includes issuing an invocation to the Auxiliary AS, the invocation including an indication of the recipient peer of the Auxiliary Service. The Auxiliary Service media data is prepared and sent to the recipient together with a correlation ID identifying the established communication exchange, and an Application Classmark identifying the auxiliary service. | 06-09-2011 |
20110150203 | Method and Arrangement for Making a Call-Setup - A method and arrangement for providing a ring-back presentation to a calling terminal after receiving a call setup request from the calling terminal (A) for a first communication session ( | 06-23-2011 |
20110314140 | Capability Query Handling in a Communication Network - 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. | 12-22-2011 |
20120331159 | Method and Apparatus for Identifying an IMS Service - A User Equipment (UE) and IP Multimedia Subsystem (IMS) network node for indicating the IMS services and IMS applications to which a Session Initiation Protocol (SIP) message relates. An IMS communication service identifier and an IMS application reference are added to the SIP message. The identifier and the reference may be added as Feature Tags. The reference may also be added as an a-line augmenting an m-line in a Session Description Protocol (SDP) part of the SIP message. | 12-27-2012 |
20130242942 | CAPABILITY UPDATE IN A TELECOMMUNICATIONS NETWORK - An apparatus configured to operate as a Service Centralization and Continuity Application Server (SCC-AS) within an IP Multimedia Subsystem network. The apparatus comprises a receiver for receiving a SIP INVITE originating from or sent via an access domain and for determining that the INVITE relates to a handover of a User Equipment (UE) currently served by the SCC-AS, to that access domain and for which a session with a peer UE is ongoing. The apparatus further comprises a message handler for determining if capabilities for the ongoing session, identified within said INVITE, have changed with respect to capabilities previously associated with the ongoing session and, if it is determined that capabilities have changed, for causing a SIP message to be sent to said peer UE, the message containing the changed capabilities. | 09-19-2013 |
20130287016 | METHOD AND USER TERMINAL FOR SUPPORTING PROVISION OF CAPABILITIES - A method in a first user terminal ( | 10-31-2013 |
20140040489 | Method and Apparatus for Identifying an IMS Service - A method of indicating IP Multimedia Subsystem (IMS) services and IMS applications to which a Session Initiation Protocol (SIP) message relates. An IMS communication service identifier and an IMS application reference are added to the SIP message. The identifier and the reference may be added as Feature Tags. The reference may also be added as an a-line augmenting an m-line in a Session Description Protocol (SDP) part of the SIP message. | 02-06-2014 |
