    摘要: A system and method for handling multimedia conference calls in a telecommunication network. To determine the capabilities of the other terminals in a group, a first terminal sends a query message to a group server. The group server sends further query messages to the other terminals and collects their responses containing their capabilities. The group server analyzes the capabilities to determine a common set of capabilities. The group server then sends the common set of capabilities in a response to the first terminal.

    摘要: A Push-to-talk over Cellular (PoC) communication session is established between an inviting PoC client and at least one invited PoC client using an IP Multimedia Subsystem network. Establishment involves using a pre-established session procedure to negotiate media parameters between the inviting PoC client and a participating PoC server for the inviting PoC client. At the inviting PoC client, a Talk Burst Control Protocol (TBCP) or Media Burst Control Protocol (MBCP) message is sent directly to its participating PoC server, the TBCP or MBCP message containing the PoC address of the at least one invited PoC client. At the participating PoC Server, in response to receipt of the TBCP or MBCP message, a SIP INVITE message is generated and sent towards a participating PoC server for the at least one invited PoC client.

    摘要: The present invention relates to a method for deregistration of a UE from an IMS, the deregistration being initiated from and performed by a P-CSCF node. The present invention also relates to a P-CSCF node comprising a processor and a memory storing a computer program, which when run in the processor, causes the P-CSCF node to perform the method. The method includes monitoring at least one parameter associated with UE behaviour in the IMS and triggering generation of a message in response to that the monitored parameter meets predefined criteria. The message is inserted in a SIP header message and sent to the S-CSCF node which forwards it to the HSS. The P-CSCF node then receives an acknowledgement from the S-CSCF node that the UE has been deregistered from the HSS and terminates the UE session with the IMS.

    摘要: A method and apparatus for indicating to a node in an IMS network a transfer between two endpoints. A node in a first network determines that a communication session is to be transferred from a first endpoint to a second endpoint. The node includes an indication of at least one of the endpoints, and an explicit communication transfer indicator, in a message. The message is then sent towards the node in the IMS network. This allows the node in the IMS network to determine that a transfer has taken place and, if necessary, take further action.

    摘要: A method and arrangement for handling a service request in a session control unit in a multimedia network. Upon receiving the service request from a user equipment, the session control unit checks a service profile associated with a user-identity of the service request in order to find an application server to which the service request is to be routed. Prior to routing the service request, an ensuring entity ensures the service request will include a primary user-identity. In the application server, the primary user-identity is used to find stored data, which is necessary for executing the requested service.

    摘要: A method and server for establishing a push to talk type service such as push to talk over cellular (PoC). The server receives a message from Client A indicating one or more media types that Client A will accept in defined circumstances in a push to talk type session. When the server receives a message from Client B inviting Client A to establish a push to talk type session for one or more proposed media types, the server determines whether the media type(s) proposed by Client B are acceptable to Client A. If at least one proposed media type is acceptable, the server forwards the invitation to Client A with a list of the acceptable media types. Thereafter the session is established.

    摘要: An apparatus and method for providing dynamic Push To over Cellular, PoC, service options in a wireless communication network. Service options and terminal capabilities for PoC Clients (11, 15) are stored in the network, preferably in a PoC Server (13). A PoC Client (11) uses a SIP PUBLISH message (17) to set the actual status of the answering mode and any barring service, and, if automatic answering mode is set, also stores a list of codecs that the PoC Client (11) supports. When the PcC Client is called, the calling PoC Client (15) informs the Server (13) of supported codecs, and the Server selects a codec supported by both Clients, thus optimizing the connection.
