Abstract
A non-call service processing method, apparatus and system in a Circuit Switch Fallback (CSFB) system are provided. The method includes that UE transmits a location updating request to VLRwhere a new LAI is located; VLRreceiving the location updating request transmits a location updating request to a HLR; the HLR receiving the location updating request transmits a location cancellation message carrying an address of VLRto VLRwhere original LAI is located; VLRreceiving the location cancellation message forwards a received non-call service request to VLR; VLRprocesses the received non-call service request, and transmits a processing result to VLR; and VLRtransmits the received processing result to the HLR or a GMLC which transmitted the non-call service request. Thus the interruption of a non-call service can be avoided, and the normal use of UE can be ensured.
