The HSCSD Network Infrastructure:
HSCSD is a circuit-switched technology. Therefore, one of its major advantages is that the existing core network, mainly the MSC, is able to handle HSCSD traffic. As opposed to GPRS, HSCSD neither requires a hardware upgrade within the network, nor does it introduce new channel coding technologies. Therefore, HSCSD is a rather simple upgrade of the standard GSM, particularly in comparison with GPRS and EDGE.
When HSCSD is added to an existing network, it is mainly the interworking functions within the MSC and, of course, the mobile stations that are affected. All other network elements and protocols remain transparent with HSCSD.
