Abstract: A communication system is provided that includes a network node, a first terminal which supports an EVS (Enhanced Voice Service) codec, and a second terminal. The EVS codec supports an AMR-WB (Adaptive Multi Rate Wideband) codec compatible mode and an AMR-WB codec non-compatible mode, the AMR-WB codec having a dedicated payload format, where the AMR-WB codec compatible mode is compatible with an AMR-WB codec and the AMR-WB codec non-compatible mode is non-compatible with the AMR-WB codec. The first terminal and the second terminal negotiate the AMR-WB codec non-compatible mode in a session negotiation to select the AMR-WB codec non-compatible mode to be used for the communication between the first terminal and the second terminal when the communication starts.

Abstract: A communication method supports Enhanced Voice Services (EVS) codec performed by a communication terminal apparatus. The method includes performing negotiation to use an EVS codec for communication between a communication terminal apparatus and a counterpart terminal, using an IP multimedia subsystem (IMS) signaling including one of a session description protocol (SDP) offer and an SDP answer, and performing negotiation to specify one or more audio-bandwidths of input signals in Hertz (Hz) or kilohertz (kHz) for the EVS codec. In a communication session after the codec negotiation session, the processor causes the receiver to receive a signaling for changing an audio-bandwidth of an input signal to the EVS codec from a network node, changes the audio-bandwidth of the input signal to the EVS codec to another audio-bandwidth without changing the EVS codec based on the signaling, and causes the transmitter to transmit encoded data in the changed audio-bandwidth.

Abstract: The present disclosure relates to auser equipment in a mobile communication system. The UE comprises processing circuitry, which in operation, determines at least one radio link via which a first base station is to forward data packets to the user equipment. The user equipment is connectable to both the first base station via a first radio link and to a second base station via a second radio link. The UE further comprises a transmitter, which in operation, transmits a radio link selection message to the first base station. The radio link selection message comprises information on the determined at least one radio link for instructing the first base station via which at least one radio link to forward the data packets to the user equipment.

Abstract: A communication terminal and method are provided, wherein a processor executes instructions to configure a codec mode or a codec mode set for a communication terminal. The configuration is based on Session Description Protocol (SDP) offer/answer messages between the communication terminal and a partner terminal in a codec negotiation session when communication starts between the communication terminal and the partner terminal, when the SDP offer/answer messages include a codec, and when a codec mode or a codec mode set is included. The processor also configures a Real-time Transport Protocol (RTP) payload format header based on the SDP offer/answer messages in the codec negotiation session, a CMR being a request for the partner terminal to change the codec mode. The processor further causes the transmitter to transmit, after the codec negotiation session, a codec mode of the communication terminal currently in use, using an RTP payload.

Abstract: A communication terminal apparatus is provided that includes a negotiator that negotiates a codec used for communication between the communication terminal apparatus and a counterpart terminal at a start of the communication. The negotiator uses an IP multimedia subsystem (IMS) signaling including one of a session description protocol (SDP) offer and an SDP answer. The negotiated codec supports bandwidths of input signals of a plurality of codecs, and changes a bandwidth of an input signal during the communication with the counterpart terminal by changing a frequency range of the input signal. The apparatus also includes a bandwidth determiner that limits the bandwidth and an encoding bit rate of the input signal of the codec during the communication with the counterpart terminal, according to signaling for limiting the bandwidth and the encoding bit rate of the input signal of the codec, the signaling being notified from a network node.
