Abstract
The present invention discloses an implementation method for location update registration, which is applied to an overlay network at least comprising a CDMA 2000 1x network and a high radio packaged data (HRPD) service. The method comprises: when a 1 x/DO dual mode terminal judges location area parameter information preserved in the interior of the 1 x/DO dual mode terminal is inconsistent with a location region parameter transmitted by a network side, an HRPD network is triggered to temporarily stop transmitting down packaged data to the terminal; then, the 1 x/DO dual mode terminal turns to the CDMA 2000 1x network for location update; after the location update is finished, the active state of the HRPD network is returned and triggered for normal data transmission. The method avoids the problem that when the user dual mode terminal of the active state of the HRPD network spans a cdma20001x network location region, CDMA 2000 1x network location update can not be carried, which causes the CDMA 2000 1x network not to page the dual mode terminal, and thus, the speech priority of the dual mode terminal in the cdma20001x network is better guaranteed.
