The Packet Data Network Gateway (PGW) serves as the backbone of MVNO operations, overseeing critical functions such as data connectivity management, IP address alloca- tion, Quality of Service (QoS) assurance, and data transmission security. Integrated within WTL’s PGW solution is the Gateway GPRS Support Node (GGSN), specifically designed for GSM and WCDMA networks. The GGSN complements the PGW by enhancing packet data connectivity management, ensuring efficient IP address allocation, and fortifying data transmission security.
