7.7.38 UTRAN Transparent Container

29.0603GPPGeneral Packet Radio Service (GPRS)GPRS Tunnelling Protocol (GTP) across the Gn and Gp interfaceRelease 17TS

The UTRAN transparent container information element contains the radio-related information. The contents of this information element are only used by the RAN so that GSN does not refer the contents.

Figure 52: UTRAN Transparent Container Information Element

Octets 4 to n shall contain one of the following information, depending of the contents of the container transported by the specific GTP Information Element:

– transparent copy of the corresponding IE (see clause 7.7.A):

– the "Source to Target Transparent Container" or the "Target to Source Transparent Container" as specified in 3GPP TS 25.413 [7]; or

– transparent copy of the octets of the encoded OCTET STRING of the "Source to Target Transparent Container" or the "Target to Source Transparent Container" specified in 3GPP TS 36.413 [51] (NOTE 1).

NOTE 1: This is for MME/SGSN interoperation via the Gn interface as specified in Annex D 3GPP TS 23.401 [47]. See also Annex C of 3GPP TS 36.413 [51] for further details on how the MME constructs the UTRAN transparent field from the Source to Target Transparent Container or Target to Source Transparent Container IEs received from S1-AP.
