Setting or updating a frame quality classifier (fqc) of a frame at a radio network controller (rnc) or media gateway (mgw) for a end-to-end frame quality classification
Setting or updating a frame quality classifier (fqc) of a frame at a radio network controller (rnc) or media gateway (mgw) for a end-to-end frame quality classification
Frame quality information is transmitted and updated within a core network (CN) and a radio access network (UTRAN) downlink to mobile user equipment (UE). In the CN, CRC checks are done and the FQC field is set according to the results of the CRC check and the received FQC field's value, and transferred to the next node in the communication path. A server, or servers instruct(s) radio gateways (MGW) and radio network controller (RNC) within the communications path to apply CRC checks and generate the FQC field according to the received FQC field and the applied CRC check. The lu framing protocol is used to transfer the FQC between the CN and a RNC. A radio protocol, such as RRC protocol, is used between the RNC and the mobile to transport to FQC field in the downlink to the UE. Within the CN, the FQC field is transported over the Nb interface.
