Manages uplink packet buffering during handover at the user equipment. Temporarily holds packets from the network layer when handover is in progress. Whether the UE is attached at all is read from a mirror of RRC's stack attachment ledger, which RRC pushes on every handover event (see BearerManagement). Releases buffered packets to the protocol stack once handover completes successfully.
