what advantage GTPv2 have more than GTPv1?
GTPv2 format is different from the GTPv1 format. GTPv2 header format does not contain any field that can carry PDU related information.
why Ciphering is done for both user plane and control plane data, why not integrity done for both data in PDCP protocol
I found 1st bit which is used to indicate that packet carrying Data/Control information. My question is that why first bit is used even packet itself known as "PDCP Data PDU".
