<p>A method and system for achieving timeframe alignment between a Centralized Base Station Controller (CBSC) (106) and a Base Transceiver Site (BTS) (102) in a network is disclosed. The BTS returns a Forward Sequence Number (FSN) contained in a forward frame and a Packet Arrival Time Error (PATE) to the CBSC. The CBSC computes a Round Trip Time (RTT), using the FSN. The CBSC also computes a forward Coordinated Universal Time (UTC), using the RTT and the PATE. Thereafter, a CBSC transmission time is adjusted to align with the BTS, based on the adjusted UTC.</p> |
