15 Mapping of BSSGP and RANAP causes

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

Table 15.1 through Table 15.4 define a mapping of BSSGP and RANAP causes used in connection with inter-RAT PS Handover to avoid different mappings in different implementations.

The cause code mapping in the MME for the inter-RAT PS Handover procedures in Annex D of 3GPP TS 23.401 [47] is described in 3GPP TS 29.010 [48].

Annex A (informative):
A method for sequence number checking

This annex describes a method to determine whether or not a received T-PDU is valid, for the Usage of the Sequence Number, clause 9.3.1.1.

This method deals with two distinct problems.

The first one is the "drifting" between the Sequence Number value that we expect to receive in the light of the total number of T-PDU received for this tunnel (the Expected value), and the effective received value. The probability that the received T-PDU is not correct because not awaited is higher if the distance between expected and received Sequence Numbers is high than if this distance is low. This leads to Condition 1. Its left part represents the distance between the Expected and received values, in a circular 65536 dimension.

The second one is the duplication of T-PDU frames within a given number of last received frames that have been accepted by the condition 1.

This leads to the following actions:

-This operation shall start when the dialogue is established between the GSNs. When each T-PDU is received during the dialogue, if this T-PDU is valid, its Sequence Number shall be saved. The last "A" saved Sequence Numbers represent the "Recorded Sequence Number Set".

A received T-PDU sequence number is valid only if it satisfies both of the following conditions:

1) Min(Abs(E – r), Abs(r – 65536 – E), Abs(E – 65536 – r)) < "B" Condition 1
Where: "E" is the Expected Sequence Number and "r" is the received Sequence Number.

2) The received Sequence Number is not a member of the Recorded Sequence Number Set. Condition 2.

"A" and "B" are parameters. The receiving GSN shall discard a received T-PDU with an invalid Sequence Number.

Abs(X) represents the absolute value of the number X.

Min(X,Y,Z) represents the lowest value taken from the numbers X, Y, and Z.

Annex B (Normative):
SGSN mapping table between Gn/Gp and NAS Cause values

The SGSN initiates session management requests towards the GGSN or mobility management requests towards the source/target SGSN. If these operations are not successful, there are several possible cause codes, which need to be mapped to appropriate cause codes over NAS to the UE.

Additionally, the 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 appropriate GTP cause codes over Gn/Gp interface towards the GGSN.

The SGSN should map these cause codes as defined in tables B.1 to B.5 unless specified otherwise in the tables.
