9.2.1 GTP Tunnel Endpoint
36.4233GPPEvolved Universal Terrestrial Radio Access Network (E-UTRAN)Release 17TSX2 Application Protocol (X2AP)
The GTP Tunnel Endpoint IE identifies an X2 transport bearer or the S-GW endpoint of the S1 transport bearer associated to an E-RAB. It contains a Transport Layer Address and a GTP Tunnel Endpoint Identifier. The Transport Layer Address is an IP address to be used for the X2 user plane transport (see TS 36.424 [8]) or for the S1 user plane transport (see TS 36.414 [19]). The GTP Tunnel Endpoint Identifier is to be used for the user plane transport. The QoS Mapping Information is used to set the IP header of packets in case that the en-gNB serves the IAB, and the packets belonging to MN-terminated split bearer/SCG bearer are transmitted from MeNB to en-gNB.
