<p>To mitigate re-syncs, RLP sync control frames associated with a packet data session can be sequence numbered. A single sequence number can be assigned for an entire sync procedure associated with the initiation of a packet data session. For example, the sequence number can remains the same on all sync control frames (SYNC, SYNC/ACK, ACK) of a particular packet data session. When a sync frame is received out of order within a single sequence, it can be ignored under certain conditions. For example, if a SYNC frame with a sequence number 0 is received out of order after an ACK frame with sequence number 0 is received, the mobile station can ignore the out of order SYNC frame. Thus, an RLP re-sync is avoided due to out of order RLP sync packets.</p> |
