Abstract

A breakout system initiates radio link control (RLC) resets to resynchronize data communication to improve quality of experience for the user. Synchronization of radio traffic is monitored and maintained by the breakout system. When data is broken out, the RLC function is split into two different flows, between the user equipment (UE) and the breakout system and between the breakout system and the radio network controller (RNC). When the sequence numbers of the two flows become out of sync the ciphering context will become out of synchronization resulting in errors. The breakout system can initiate an RLC reset into both of these flows to resynchronize the data communication to improve user's quality of experience.
