Abstract
A mobile telephone network provides a network operator domain (2a) in which the output from a radio network controller (RAN) (14a) is processed by a voice capable serving GPRS support mode (30) (VC-SGSN). The VC-SGSN (30) consists of the combination of a voice service box (32) (VSB) and a serving GPRS support node (34) (SGSN). The VSB (32) and the SGSN (34) can jointly access the same home location register (36). The output of the SGSN (34) can be forwarded to the Internet (6a) via a gateway GPRS support node (20a) while the output of the VSB (32) can be forwarded to the public switched telephone network (4a) (PSTN).
Claims6
A mobile network domain comprising a radio network controller (RNC) for supplying signals derived from user equipment, in packet form, a voice capable serving GPRS (general packet radio system) support node (VC-SGSN) for receiving signals from the RNC and processing both voice and non-voice packet signals, a gateway GPRS support node (GGSN) for receiving non-voice packet signals processed by the VC-SGSN and forwarding them out of the domain, and a home location register (HLR) containing subscriber identity, service and billing requirements, the VC-SGSN comprising the combination of a servicing GPRS support node (SGSN) and a voice service box (VSB) both of which can communicate with the HLR to access data therein and to transfer data thereto, the VSB receiving and processing voice packet signals and when processed forwarding this out of the domain.
