ABSTRACT:
A method for an Access Terminal (AT) in a 1x network to establish an High Rate Packet Data (HRPD) network packet data service includes: initiating, by the AT, a session establishment request to a target Access Network/Packet Control Function (AN/PCF) of an HRPD network; establishing, by the target AN/PCF, an HRPD session with the AT after obtaining session information of an existing HRPD session; performing, by the target AN/PCF and the AT, session configuration based on the obtained session information, and establishing a data connection for the packet data service. In the present invention, an AT in the 1x network can establish a packet data service with an HRPD network when there is an existing packet data session in the HRPD network. The present invention is advantageous for seamless service handoff between the 1x network and the HRPD network, thereby realizing complement of the two networks and improving user experience.
