What is the difference between GTPv0, GTPv1 and GTPv2?

Question

My question is related to the Proxy server IP address configured in the APN settings in the Mobile.

Is it possible to achieve that the Proxy server IP address configured in the MS will not take effect by controlling it via GTP-C message from the GGSN to the SGSN or from PGW to MME (via SGW).

For instance, is there any identifier in the PCO (Protocol Configuration option) container in the create-PDP-context-response or Create-session-response that control and disable/overwrite the proxy server for the attempted data-session. As a result, the mobile will not generate the user-data traffic to the proxy server IP configured on it.

Answer 1

GTP was originally standardized within ETSI (GSM standard 09.60). With the creation of the UMTS standards this was moved over to the 3GPP which, as of 2005 maintains it as 3GPP standard 29.060. GTP' uses the same message format, but its special uses are covered in standard 32.295 along with the standardized formats for the charging data it transfers.

Later versions of TS 29.060 deprecate GTPv1/v0 interworking such that there is no fallback in the event that the GSN does not support the higher version.

GTPv2 (for evolved packet services) went into draft in early 2008 and was released in December of that year. GTPv2 offers fallback to GTPv1 via the earlier "Version Not Supported" mechanism but explicitly
offers no support for fallback to GTPv0.

GTPv2 is used in LTE (TLIV format) and GTPv1/GTPv0 used in UMTS (TLV format).

Answer 2

GTPV0 - GSM
GTPV1 - GPRS, 3G, LTE..
GTPV2 - LTE..

LTE will support all these version.
