Title:
SYSTEM AND METHOD OF SINGLE RADIO VOICE CALL CONTINUITY HANDOVER REDUCTION
Document Type and Number:
WIPO Patent Application WO/2018/144345
Kind Code:
A3
Abstract:
Systems and methods of handover are disclosed. The PCRF decodes IMS service information for voice media from a P-CSCF. The IMS service information contains codec information of a UE. The PCRF sets, based on the codec information in the IMS service information, a Maximum Packet Loss Rate for uplink and downlink communications between the UE and an eNB. The PCRF generates a PCC rule for the voice media and encodes the PCC rule for transmission to a PCEF. The PCC rule includes the Maximum Packet Loss Rate for both directions. The codec information indicates which of a high robustness codec or a low robustness codec is being used by the UE. The eNB uses the codec information to determine handover thresholds and whether SRVCC handover is to occur for the UE.
