Various embodiments are described to address the need for reduced handoff delays associated with inter-AN (access network) HRPD (High Rate Packet Data)/1xEV-DO handoffs. The disclosed approach enables an AT ( 101 ) with an active packet data session to perform a hard handoff from a source AN ( 121, 221 ) to a target AN ( 122, 222 ) without having to force the data session dormant. Unlike known hard handoff approaches that involve coordination by a mobile switching center (MSC), the disclosed approach uses peer-to-peer signaling with no MSC involvement, such as that between source and target ANs or PCFs ( 131, 132, 231, 232 ). For example, data session information at the source side is transferred via new A13 messaging to the source entity's target-side peer to otherwise reduce signaling between the source and target equipment.
