Abstract:
1. A method of maintaining frame quality of data being transported in a telecommunications system from a first user equipment (UE) through a core network (CN) to a second UE, the method comprising the steps of: (a) performing, at a first radio network controller (RNC), a cyclic redundancy check (CRC) on at least one radio bearer frame being received from the first UE; (b) setting, at the first RNC, a frame quality classifier (FQC) field according to the results of the CRC; (c) forwarding a corresponding frame with the set FQC field to a first media gateway (MGW) in the CN via an lu UP interface; (d) forwarding the corresponding frame with the set FQC field to at least one other MGW in the CN via a Nb UP interface; and (e) forwarding the corresponding frame with the set FQC field to a second RNC associated with the second UE via a second lu UP interface.
