Abstract
The invention discloses a method of location updating register. It applies in the superposition network which includes at least CDMA 1x network and High Ratio Packet Data (HRPD) traffic network. The method includes: trigging the HRPD network to pause sending down ranging data to the terminal when found the 1x/DO dual-modulus terminal judged the location area parameter data saved itself not corresponding to that sent from the network side; then, turning into the CDMA2000 1x network for updating; when finished location updating, trigging again and returning to HPRD network to normal data transmission in active state. The method avoids the user's dual-modulus terminal in the active state of HRPD network can not run CDMA200 1x network location updating when crossing the CDMA2000 1x network location and cause CDMA2000 1x can not call the dual-modulus terminal.
