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.
