<p>A method for switch between the activation status ANS in HRPD network and the system thereof, including: when the switch between the access network AN is determined, then starts up the switch operate, and processes the switch between the ANs, during the switch, it transmits the data to target AN, the data is that will be transmitted to the terminal; then, according to the switch process result, the data needed transmit to the terminal during the switch is transmitted to the terminal by source AN or the target AN. It can be seen that the method of present invention can improve the continuity of service; even if the AN switch is failure, but because the source PCF receives the PDSF data all along during the switch, so when the terminal falls back to the source AN, source PCF can transmit the data information when the switch is started, so the continuity of service is improved.</p> |
