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: Methods and systems are disclosed for supporting delay budget information in IMS systems. Requests for DBI are received by a first node, contained within a SIP message. This can be achieved by filling a feedback field within the signal with a delay budget indicator. The first node analyzes the received signal in order to determine whether DBI is being requested. Based on this analysis, a request signal is forwarded to a second node, which carries out resource reservation. The request signal can be based on a H.248:Add.req message. In this manner, DBI can be signaled and supported even without dedicated DBI messaging.

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.
