WCDMA Core Network satisfies the rapidly-growing demand for mobile data transport to any location in the world.
MSC-Server controls call processes and media gateway that provides a voice path. It performs call control (CC), mobility management (MM), and visitor location register (VLR) among WCDMA MSC functions. For these functions, it connects the RdNC under the RANAP (Iu-UP Control Plane) protocol and functions as a system node that controls the MGW switching function.
Media Gateway is a scalable powerful but compact ATM based multi service switching platform for circuit switched domain to carry voice & multimedia traffic. It also provides seamless inter-working of voice connections between PSTN, IP and 3G Networks, has media resource functions including tone generation, announcements, and conference calls. Samsung MGW is fully compliant with 3GPP Rel4, and delivers up to 20 Gbps of switching capacity
SGSN supports WCDMA packet switching service and general packetradio service (GPRS) to ensure the mobility of packet service users. By inter-working with GGSN, it configures the packet switching module, or transport platform (TP), and the packet call processing module, or managed intelligence platform (MIP).
GGSN processes bearer traffic to and from SGSN and Internet. It performs service capabilities creation, session management. packet segment and assemble, and DIAMETER credit control accounting for prepaid billing, etc. With QoS features, it enable precise bandwidth allocation of radio resources.
