Abstract
A method, system and computer readable medium for providing access network bit rate recommendation for Voice over Long Term Evolution (VoLTE) Coder Decoder (CODEC) change using dynamic VoLTE allocation is presented. In one embodiment a method includes determining, by an eNodeB, if Transmit Time Intervals (TTI) bundling is configured for a User Equipment (UE); and when TTI bundling is not configured, then sending an Access Network Bitrate Recommendation (ANBR) Medium Access Control (MAC) SE for VoLTE CODEC decrease.
Claims8
A method for providing access network bit rate recommendation for Voice over Long Term Evolution (VoLTE) Coder Decoder (CODEC) change using dynamic VoLTE allocation (DVA),
- the method comprising:
- determining, by an eNodeB, if Transmit Time Interval (TTI) bundling is configured for a User Equipment (UE);
- when TTI bundling is not configured, then determining when RLC segmentation would need more than a predetermined number of segments;
- when TTI bundling is not configured, then sending an Access Network Bitrate Recommendation (ANBR) Medium Access Control (MAC) control element (CE) for VoLTE CODEC decrease;
- and
- when TTI bundling is not configured, then determining whether UL link adaptation supports VoLTE transport block, wherein, when the UL link adaptation cannot support the VoLTE transport block, and the RLC segmentation would need more than the predetermined number of segments, the ANBR is triggered to send the ANBR MAC CE for the VoLTE CODEC decrease.
A non-transitory computer-readable medium containing instructions for providing access network bit rate recommendation for Voice over Long Term Evolution (VoLTE) Coder Decoder (CODEC) change using dynamic VoLTE allocation (DVA) which, when executed, cause a system to perform steps comprising:
- determining, by an eNodeB, if Transmit Time Interval (TTI) bundling is configured for a User Equipment (UE);
- when TTI bundling is not configured, then determining when RLC segmentation would need more than a predetermined number of segments;
- when TTI bundling is not configured, then sending an Access Network Bitrate Recommendation (ANBR) Medium Access Control (MAC) control element (CE) for VoLTE CODEC decrease;
- and
- when TTI bundling is not configured, then determining whether UL link adaptation supports VoLTE transport block, wherein, when the UL link adaptation cannot support the VoLTE transport block, and the RLC segmentation would need more than the predetermined number of segments, the ANBR is triggered to send the ANBR MAC CE for the VoLTE CODEC decrease.
