1. A method, comprising:
- receiving, at a radio network controller and from a second base station, a notification that the second base station has detected that a mobile unit has switched its serving base station from a first base station to the second base station; and
providing, from the radio network controller, at least one signaling message to the second base station for transmission to the mobile unit in response to receiving the notification, wherein the radio network controller provides said at least one signaling message before the radio network controller receives, from the first base station, information indicating at least one of a sequence number or a frame number, wherein the sequence number or frame number is associated with at least one data frame previously transmitted to the mobile unit.

8. A method, comprising:
-
receiving, at a mobile unit, at least one prior data frame from a first base station, said at least one prior data frame being associated with at least one of a sequence number or a frame number; switching the mobile unit'"'"'s serving base station from the first base station to a second base station; receiving at least one signaling message from the second base station, wherein the mobile unit receives said at least one signaling message before a radio network controller receives information indicating at least one of the sequence number or the frame number from the first base station, and wherein said at least one signaling message is provided in response to the second base station providing at least one notification to the radio network controller indicating that the second base station has detected that the mobile unit switched serving base stations. - View Dependent Claims (9, 10, 11, 12)

13. A method, comprising:
-
providing, from a mobile unit, a notification that the mobile unit is switching serving base stations from a first base station to a second base station; receiving, at the mobile unit, at least one signaling message from the second base station, wherein the mobile unit receives said at least one signaling message after the second base station has informed a radio network controller that it has detected the switch and before the radio network controller has received information from the first base station indicating at least one of a sequence number or a frame number associated with at least one prior data frame. - View Dependent Claims (14, 15, 16, 17)
