28、cal Specification has been produced by the 3rdGeneration Partnership Project (3GPP). The contents of the present document are subject to continuing work within the TSG and may change following formal TSG approval. Should the TSG modify the contents of the present document, it will be re-released by

29、the TSG with an identifying change of release date and an increase in version number as follows: Version x.y.z where: x the first digit: 1 presented to TSG for information; 2 presented to TSG for approval; 3 or greater indicates TSG approved document under change control. y the second digit is incre

30、mented for all changes of substance, i.e. technical enhancements, corrections, updates, etc. z the third digit is incremented when editorial only changes have been incorporated in the document. ETSI ETSI TS 129 281 V15.3.0 (2018-07)63GPP TS 29.281 version 15.3.0 Release 151 Scope The present documen

31、t defines the user plane of GTP used on: - the Gn and Gp interfaces of the General Packet Radio Service (GPRS); - the Iu, Gn and Gp interfaces of the UMTS system; - the S1-U, S11-U, S2a, S2b, X2, S4, S5, S8, S12, M1 and Sn interfaces of the Evolved Packet System (EPS); - the Xn, N3 and N9 interfaces

32、 of the 5G System (5GS); This definition ensures full backwards compatibility with RNC, SGSN and GGSN implementations according to release 7 of 3GPP TS 29.060 6. NOTE: Releases previous to Release-8 have used 3GPP TS 29.060 6 as normative definition of the user plane of GTP. This shall be considered

33、 when essential corrections are included in the present document or in pre-release-8 version of 3GPP TS 29.060 6. Fallback from GTPv1-U to GTPv0-U shall not be supported. Therefore, 3GPP Rel-8 and onwards GTPv1-U entity should not listen to the well-known GTPv0 port 3386. If GTPv1 entity listens to

34、the GTPv0 port, the entity shall silently discard any received GTPv0-U message. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. - References are either specific (identified by date of publication, edition n

49、a given UDP/IP endpoint. The sending end side of a GTP tunnel locally assigns the C-TEID value used in the TEID field and signals it to the destination Tunnel Endpoint using a control plane message. GTP-U Message: GTP-U (user plane) messages are either user plane messages or signalling messages. User plane messages are used to carry user data packets between GTP-U entities. Signalling messages are sent between network nodes for path management and tunnel management. GTP-U Tunnel: A GTP-U tunnel is
