Abstract
The public switched telephone network (PSTN) (120) is coupled to both the central switch (MSC) (102) and the base station controller (BSC) (101, 110). A call placed to the BSC (101) can be routed to a base station (103-105) by the BSC (101) or to the MSC (102) for routing to the PSTN (120) or another BSC (110). The MSC (102) processes the signalling information routed from the BSC (101). If a call is placed to the MSC (102), the MSC (102) routes the call to the appropriate BSC (101, 110) while also processing the signalling information.
