摘要:
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.

摘要:
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.

摘要:
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.
摘要:
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.
摘要:
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.
摘要:
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 (308) with a called terminal (B). A second packet-based communication session (310) is established with the calling terminal, independent of the first session, and pre-defined media content is provided as said ring-back presentation (312) to the calling terminal over the second session. Thereby, ring-back presentations to waiting callers can be selected from a great range of media types, including visual media. A calling user can also control the playout or display of the ring-back presentation irrespective of when the call is answered.
