B.2 Support for SIPTO at Iu-ps
23.0603GPPGeneral Packet Radio Service (GPRS)Release 17Service descriptionStage 2TS
This clause describes the functionality that an SGSN provides if the SGSN supports the "SIPTO at Iu-ps" function. Support for the "SIPTO at Iu-ps" function is optional in the SGSN.
During the SRNS Relocation Procedures (in clauses 6.9.2.2.1, 6.9.2.2.2 and 6.9.2.2.3):
– If the SGSN has valid subscriber data before it sends Relocation Request message to the target RNC, and SIPTO function should be activated for the APN of the RAB to be setup according to the subscriber data and operator policies, the SGSN shall include the MSISDN in the Relocation Request message (in step 4), and include the APN and the Charging characteristics in the RABs to be setup IE for the RAB to be offloaded to enable Iu-ps traffic offload and charging for the offload traffic.
– If the SRNS Relocation is inter-SGSN and the new SGSN does not have valid subscriber data before it sends Relocation Request message to the target RNC, and SIPTO function should be activated for the APN of the RAB to be setup according to the subscriber data and operator policies, the new SGSN shall initiate a RAB assignment procedure after Routing Area Update procedure (after step 15) to enable Iu-ps offload and transfer the charging parameters to the Traffic Offload Function. The SGSN includes MSISDN in the RAB Assignment Request message, and includes the APN and the Charging characteristics in the RABs to be setup IE for the RAB to be offloaded.
During Service Request Procedures (in clauses 6.12.1 and 6.12.2):
– If SIPTO function should be activated for the APN of the RAB to be setup according to the subscriber data and operator policies, the SGSN shall include the MSISDN in the RAB Assignment Request message (in step 4 of clause 6.12.1, step 6 of clause 6.12.2), and include the APN and the Charging characteristics in the RABs to be setup IE for the RAB to be offloaded to enable Iu-ps traffic offload and charging for the offload traffic.
During the intersystem change procedures from A/Gb mode to Iu mode (in clauses 6.13.1.2.1 and 6.13.2.2.1):
– If SIPTO function should be activated for the APN of the RAB to be setup according to the subscriber data and operator policies, the SGSN shall include the MSISDN in the RAB Assignment Request message (step 11 of clause 6.13.1.2.1, step 20 of clause 6.13.2.2.1), and include the APN and the Charging characteristics in the RABs to be setup IE for the RAB to be offloaded to enable Iu-ps traffic offload and charging for the offload traffic.
During RAB Assignment procedure (in clause 12.7.4.1):
– If SIPTO function should be activated for the APN of the RAB to be setup according to the subscriber data and operator policies, the SGSN shall include the MSISDN in the RAB Assignment Request message (step 1), and include the APN and the Charging characteristics in the RABs to be setup IE for the RAB to be offloaded to enable Iu-ps traffic offload and charging for the offload traffic.
Annex C (informative):
Link MTU considerations
According to clause 9.3 networks can provide link MTU size for MSs. A purpose of the link MTU size provisioning is to limit the size of the packets sent by the MS to avoid packet fragmentation in the backbone network between the MS and the GGSN/PGW (and/or across the (S)Gi reference point) when some of the backbone links does not support packets larger then 1500 octets. Fragmentation within the backbone network creates a significant overhead. Therefore, operators might desire to avoid it. This Annex presents an overhead calculation that can be used by operators to set the link MTU size provided by the network. A MS may not employ the provided link MTU size, e.g. when the MT and TE are separated, as discussed in clause 9.3. Therefore, providing an MTU size does not guarantee that there will be no packets larger than the provided value. However if MSs follow the provided link MTU value operators will benefit from reduced transmission overhead within backbone networks.
One of the worst case scenarios is when GTP packets, e.g., between a RAN node and the core network, are transferred over IPSec tunnel in an IPv6 deployment. In that case the user packet first encapsulated in a GTP tunnel which results the following overhead:
– IPv6 header, which is 40 octets;
– UDP overhead, which is 8 octets;
– Extended GTP-U header, which is 16 octets.
NOTE: The sending of SCI in the GTP-U header will increase the GTP-U header size (see TS 29.281 [120]).
In this scenario the GTP packet then further encapsulated to an IPSec tunnel. The actual IPSec tunnel overhead depends on the used encryption and integriry protection algorithms. TS 33.210 [114] mandates the support of AES-CBC with a key length of 128 bits and the use of HMAC_SHA-1 for integrity protection. Therefore the overhead with those algorithms is calculated in this Annex:
– IPv6 header, which is 40 octets;
– IPSec Security Parameter Index and Sequence Number overhead, which is 4+4 octets;
– Initialization Vector for the encryption algorithm, which is 16 octets;
– Padding to make the size of the encrypted payload a multiple of 16;
– Padding Length and Next Header octets (2 octets);
– Integrity Check Value, which is 12 octets.
In order to make the user packet size as large as possible a padding of 0 octet is assumed. With this zero padding assumption the total overhead is 144 octets, which results a maximum user packet size of 1358 octets. Note that this user packet size will result in a 1424 octets payload length to be ciphered, which is a multiple of 16, thus the assumption that no padding is needed is correct (see Figure C.1).
Figure C.1: Overhead for MTU calculation
The link MTU value that can prevent fragementation in the backbone network between the MS and GGSN/PGW depends on the actual deployement. Based on the above calculation a link MTU value of 1358 is small enough in most of the network deployements.
Note that using a link MTU value smaller than necessary would decrease the efficiency in the network. Moreover a UE may also apply some tunnelling (e.g., DSMIPv6 or VPN). and it is desired to use a link MTU size that assures at least 1280 octets, which is the minimum MTU size in case of IPv6, within the UE tunnel to avoid the fragmentation of the user packets within the tunnel applied in the UE.
Another aspect of the dynamic link MTU provisioning is that in the future when all network links support larger packet sizes than 1500 octets, operators can send a value larger than 1500 octets as a link MTU size to MSs. This option is useful for operators as if an MS uses large packets then it will increase the transport efficiency in the network.
The above methodology can be modified for calculation of the UE’s link MTU when a PDN GW has MTU limits on the SGi reference point and is offering a "non-IP" connection between the PDN GW and the UE,
