Abstract
A mobile telephone network provides a network operator domain in which the output from a radio network controller (RAN) is processed by a voice capable serving GPRS support mode (VC-SGSN). The VC-SGSN consists of the combination of a voice service box (VSB) and a service GPRS support node (SGSN). The VSB and the SGSN can jointly access the same home location register). The output of the SGSN can be forwarded to the internet via a gateway GPRS support node while the output of the VSB can be forwarded to the public switched telephone network (PSTN).
