The Packet Control Unit (PCU) is a late addition to the GSM standard. It performs some of the processing tasks of the BSC, but for packet data. The allocation of channels between voice and data is controlled by the base station, but once a channel is allocated to the PCU, the PCU takes full control over that channel.

The PCU can be built into the base station, built into the BSC or even, in some proposed architectures, it can be at the SGSN site. In most of the cases, the PCU is a separate node communicating extensively with the BSC on the radio side and the SGSN on the Gb side.

More specifically The Packet Control Unit is a device found within a GPRS network which is logically associated with a BSC (Base Station Controller). The PCU is responsible for the radio related aspects of GPRS when connected to a GSM network and lies between the BTS (Base Transceiver Station) and the SGSN (Serving GPRS Support Node).
