All-IP Network (AIPN)
AIPN provides enhanced performance, future-proof scaling and reduction of inter-connectivity complexity.
In accordance with 3GPP, the SGSN provides IP-based transport on all RAN and core network interfaces, in addition to
the standard IP-based interfaces (Ga, Gn, Gp, Iu-Data). The all-IP functionality is key to facilitating Iu and Gb Flex
(SGSN pooling) functionality as well as evolution to the next generation technology requirements.
