B.3 Other RANAP and S1-AP and NGAP IEs

29.2743GPP3GPP Evolved Packet System (EPS)Evolved General Packet Radio Service (GPRS) Tunnelling Protocol for Control plane (GTPv2-C)Release 18Stage 3TS

When transparently copying a RANAP/S1AP/NGAP IE, other than the handover/relocation related generic transparent containers (see Annex B.1) into GTP IE, or GTP IE field the following applies:

– a transparent copy of a RANAP/S1AP/NGAP IE, which is transported on the Iu/S1/NG-C interface within a "protocol-IE container", neither includes the Information Element Identity ("IE-ID") nor the "criticality" nor the open type field related length indication ("OT-LI"), but only the Information Element itself ("IE").

– "IE" refers to all parts of the encoded type of the Information Element, i.e. including also any related length indication (in case of types with variable length) and preamble (see ITU-T X.691 [49] for the definition of the term "preamble").

Annex C (Normative):
MME/S4-SGSN mapping table between S11/S4 and NAS Cause values

The MME/S4-SGSN initiates session management requests towards the SGW and PGW or mobility management requests towards the source/target MME/S4-SGSN. If this operation is not successful, there are several possible cause codes, which need to be mapped to the appropriate cause codes over NAS to the UE.

Additionally, the MME/S4-SGSN initiates session management requests towards the UE. If this operation is not successful, there are several possible NAS cause codes which need to be mapped to the appropriate GTP cause codes over S11/S4 interface towards the SGW.

The MME/S4-SGSN should map these cause codes as defined in tables C.1 to C.5 unless specified otherwise in the tables.

NOTE 1: See 3GPP TS 24.301 [23] and 3GPP TS 24.008 [5] for NAS ESM and SM causes respectively.

NOTE 2: The MME/S4-SGSN may for certain GTP cause codes trigger a new GTP procedure instead of rejecting the NAS request.

NOTE 3: When multiple NAS Cause values are defined for a given GTP cause value, any of those NAS Cause values may be sent to the UE based on implementation choice.

NOTE 4: The MME may send in addition the EMM cause code set to #15 "No suitable cells in tracking area" to the UE, if the PDN connectivity request is rejected due to the ESM cause #29, which is mapped from the GTPv2 cause code #92 based on operator policies. See 3GPP TS 24.301 [23]. This enables a roamer to get service in a VPLMN even when being rejected via LTE access due to e.g. no credit authorisation from the OCS.
