摘要： A UE includes an EUTRA-CMR reception unit that receives a codec mode request (EUTRA-CMR) including a codec mode that is determined by an eNB in accordance with a radio condition of the UE, a mode switching notification unit that notifies an encoder of switching to the codec mode included in the received codec mode request; and a mode switching acknowledgement unit that transmits a response message to the eNB when confirming that the encoder switches the codec mode.

摘要： A Session Initiation Protocol (SIP) message containing a Session Description Protocol (SDP) offer for a communications session is sent to a first endpoint. The SDP offer includes a first parameter indicating whether the communications session will include media encoding TTY data, audio data, or both TTY data and audio data. An error response is received that indicates the device has rejected the first parameter. Based on the error response to the first endpoint, a modified SIP message containing the SDP offer for the communications session is sent to the first endpoint. The SDP offer of the modified message excludes the first parameter indicating whether the communications session will include media encoding TTY data, audio data, or both TTY data and audio data.

摘要： Incoming calls are received from audio capable devices. A call processing server receives an incoming call from an audio-capable device to a destination number, and detects availability for an ancillary source device linked to the audio-capable device. A set of data is provided to the ancillary source device. The set of data specifies graphical menu options for functions supported by the call processing server. The ancillary source device provides an indication of a selection of one of the graphical menu options. In response to the indication, a call transfer for the incoming call is implemented.

摘要： A network that is to execute transcoding is fixed. IMS networks (SBC 1a and SBC 1b) set an information element that requests either of the IMS networks to execute transcoding into the SDP, and use that information element to select the IMS network (SBC 1a or SBC 1b) that is to execute transcoding between the IMS networks (between SBC 1a and SBC 1b). Then, the selected IMS network executes transcoding of media data.

摘要： Provided is a server system robust against a communication path failure. A first server system 2-1 and a second server system 2-2 are respectively installed on a first network 3-1 and a second network 3-2 provided by common carriers different from each other. The first and second server systems are connected to each other by a dedicated line 6. Even when a failure occurs in the first network, communication through the second network can be maintained, and even when a failure occurs in the second network, communication through the first network can be maintained. Further, when a failure occurs in the dedicated line, operations can be performed within each of the first and second networks in a degeneracy mode.
