Patent ID: 8724582

Claim:
A method comprising: in response to handoff of a mobile station from an anchor radio network associated with an anchor packet data serving node to a target radio network associated with a target packet data serving node, buffering a datagram destined for the mobile station that is received in the target packet data serving node; receiving dynamic contexts in the target packet data serving node that are transferred from the anchor packet data serving node; and after the handoff has been performed, forwarding the buffered datagram to the mobile station via the target radio network; where prior to receiving the dynamic contexts, the method comprises receiving static contexts in the target packet data serving node from the anchor packet data serving node; where the dynamic contexts are received in the target packet data serving node from the anchor packet data serving node subsequent to the datagram being buffered by the target packet data serving node; and where the buffered datagram is forwarded to the mobile station from the target packet data serving node in accordance with the dynamic contexts and with the static contexts received from the anchor packet data serving node.
