In the mobile communication device, a wireless module performs wireless transmissions and receptions to and from a first cellular station and a second cellular station, and a controller module configures the mobile communication device to operate in a selective retransmission mode, and detects that a signal quality of the first cellular station is less than a predetermined threshold during an access sub-attempt to the first cellular station via the wireless module. Also, the controller module hands off the mobile communication device from the first cellular station to the second cellular station in response to detecting that the signal quality of the first cellular station is less than a predetermined threshold, and clears a physical layer buffer and restarts a selective acknowledgement (SACK) operation for the selective retransmission mode after the handoff of the mobile communication device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Apparatus and method for access probe handoff","description":"A mobile communication device for access probe handoff is provided.
