Abstract: Methods, systems, and storage media are described for providing codec mode notification (CMN) messages for speech to be signaled from a sender to a receiver. Other embodiments may be described and/or claimed.

Abstract: In some embodiments, during the SIP registration, the UE indicates in the REGISTER requests its support for ANBR as defined by “ANBR” attribute in the SDP and the P-CSCF indicates its support for the “ANBR” attribute in the SDP in the response for registration. In some embodiments, the P-CSCF serving a PLMN passes through the “ANBR” attribute in the SDP when the P-CSCF recognizes that the PLMN supports ANBR functionality. In some embodiments, the UE can include “ANBR” attribute in the SDP offer and answers when the P-CSCF indicates its support for the “ANBR” attribute in the SDP.

Abstract: Provided herein are apparatus and method for signal RAN-assisted codec adaptation capabilities via IMS. An apparatus for a UE includes a RF interface to receive an SDP offer message from the remote UE, the SDP offer message including a first dedicated SDP attribute parameter to indicate support of ANBR capability of the remote UE; and processor circuitry. The processor circuitry is to decode the SDP offer message to determine the support of ANBR capability of the remote UE; encode an SDP answer message in response to the SDP offer message, the SDP answer message including a second dedicated SDP attribute parameter to indicate support of ANBR capability of the UE; and cause transmission of the SDP answer message to the remote UE. Other embodiments may also be disclosed and claimed.

Abstract: Apparatuses of user equipment (UEs) for end-to-end coordination of voice over cellular data network communications. An apparatus of a UE includes one or more data storage devices and one or more processors. The one or more data storage devices are configured to store delay budget information pertaining to end-to-end delivery of a real-time transport protocol (RTP) stream sent from a remote UE to the UE. The one or more processors are configured to generate an application layer message including the delay budget information, the application layer message to be transmitted to the remote UE to enable the remote UE to request, from a cellular base station servicing the remote UE, additional air interface delay based on the delay budget information.

Abstract: Techniques described herein may increase the efficiency of a network by ensuring that bearers, used in anonymous (e.g., emergency) calls are properly deactivated. A user equipment (“UE”) may maintain an inactivity timer after an emergency call has ended, and may request that the network deactivate the bearer upon expiration of the inactivity timer, if the bearer is still active upon the expiration of the inactivity timer.
