  • METHOD AND APPARATUS TO MINIMIZE PACKET LOSS DURING ACTIVE DATA HARD HANDOFF
    Publication number: 20070165574
    Abstract: A method of hard handoffs begins by establishing a wireless link between a source radio access network (102a) and a mobile station (106). When the mobile station moves into another adjacent radio access network (102b), the present invention detects that handoff of the link from the source to the target is necessary. Additional data is not sent to the mobile station from the source radio access network. The data that has not been received by the mobile station is stored or buffered. A disconnect message is received by the source and a connect message is received by the target so that an active handoff is achieved between the source and the target. When the active handoff procedure is complete the data that was buffered by the source BTS as not being received by the mobile station is then sent to the active target cell such that data and packet loss is reduced.
