In a mobile data network with a breakout system, when data is broken out, the RLC function is split into two different flows, between the UE and the breakout system and between the breakout system and the RNC. These two flows are processed by different RLC functions that may drift apart and become out of synchronization resulting in errors that diminish the user's quality of experience. Other errors may also occur in communication on these two different flows. The breakout system attempts to correct these errors using data stored locally in communication data structures for the two data flows. If the errors cannot be corrected, the breakout system can initiate an RLC reset into both of these flows to resynchronize the data communication.
