摘要
A call processing system in a CDMA(Code Division Multiple Access) 1x EV-DO(Evolution Data Optimized) network is provided to integrate two MSCs(Mobile Switching Centers) into one virtual MSC to supply a data service to one DLR(Data Location Register), thereby offering a high-quality service without increasing systems and radio resources though traffic is increased. ANC(Access Network Control) units(11-14), MSCs(21-24), DLRs(31,32), and an HDLR(Home Data Location Register)(40) are mutually interworked. At least two of the MSCs(21-24) are integrated into one virtual MSC, so that the integrated MSC is connected with one of the DLRs(31,32) to provide a data call processing service. In order to provide the data call processing service, A13(hand-off) messages and UATIs(Unicast Access Terminal IDs) of the DLRs(31,32) are allocated.
