- CSFB Circuit Swiched Fallback
- the SGs interface between the Mobility Management Entity (MME) and the Mobile Switching Center (MSC) 1 that is needed in Circuit Swiched Fallback (CSFB) in order to both create, and maintain, both the attachment of the User Equipment to the Mobile Switching Center (MSC) for a User Equipment (UE) connected to or requesting a connection to the Evolved Packet System (EPS) and to perform paging for mobile terminating call, was extended to allow also the transfer of short messages to and from the UE.
- ETSI TR 21.905 V8.8.0 the term MME stands for Mobile Management Entity; according to TS23.401 , V8.6.0 this term stands for Mobility Management Entity; hereinafter, the term Mobility Management Entity is used.

- IWF Interworking Function
- Interworking Function for the necessary functions rather than enforcing an upgrade of all Mobile Switching Center (MSC) units.
- the functionality of the Interworking Function (IWF) is much less than a full-blown Mobile Switching Center (MSC); in essence, the Interworking Function (IWF) has only minimal functions of an Mobile Switching Center (MSC) on top of what would have to be added to an Mobile Switching Center (MSC) in order to support SMS via SGs.
- Further simplifications of the overall functionality can be achieved when integrating the Interworking Function (IWF) into the Mobility Management Entity (MME) (e.g. no need for VLR number derivation and the SGs interface) or into the Short Message Service Center (SMSC) (e.g. no need for Home Subscriber Server (HSS) location area updating and the MAP interface towards the Short Message Service Center (SMSC)).
- MME Mobility Management Entity
- SMSC Short Message Service Center
- HSS Home Subscriber Server
- the unit providing the Interworking Function is an intermediate unit having an SGs interface with the Mobility Management Entity (MME) and an interface with the Short Message Service Center (SMSC) as defined in clause 4.2 in TS23.040 (clause 4.2 "Transfer on reference point 3" according to 3GPP TS 23.040 version 8.5.0).
- MME Mobility Management Entity
- SMSC Short Message Service Center
- Such an interface is hereinafter also called an "SMSC-interface”.
- SMSC-interface can, e.g., be realised by means of a MAP-interface (Mobile Application Part interface according to TS29.002) but other realizations are also possible according to TS23.040.
- the unit providing the Interworking Function is integrated in the Short Message Service Center (SMSC), having an SGs interface with the Mobility Management Entity (MME).

- a first step of the attach procedure designated by AT1 corresponds to the attach request of the User Equipment (UE) towards the Mobility Management Entity (MME).
- a second step of the attach procedure designated by AT2, corresponds to steps 2 to steps 17 of the Attach procedure specified in TS 23.401 ( Figure 5.3.2.1-1 : "Attach procedure" according to document "3GPP TS 23.401 version 8.6.0").
- a third step of the attach procedure, designated by AT3 corresponds to deriving the Visitor Location Register (VLR) number.
- VLR Visitor Location Register
- a fourth step of the attach procedure corresponds to the Mobility Management Entity (MME) sending a Location Update Request to the Mobile Switching Center / Visitor Location Register (MSC/VLR).
- a fifth step of the attach procedure designated by AT5, corresponds to the creation of an SGs association.
- a sixth step of the attach procedure designated by AT6, corresponds to a Location update in the circuit switched domain.
- a seventh step of the attach procedure designated by AT7, corresponds to the Mobile Switching Center / Visitor Location Register (MSC/VLR) sending a Location Update Accept to the Mobility Management Entity (MME).
- the User Equipment has to perform a combined attach (i.e., attaching to both the Evolved Packet System (EPS) and the circuit switched (CS) system).
- EPS Evolved Packet System
- CS circuit switched
- the attach procedure is limited by either the User Equipment (UE) requesting attach to the MSC/VLR only for SMS, or by the network returning acceptance for SMS only.
- the third step of the attach procedure AT3 is implementation specific in the Mobility Management Entity (MME) and does not need to take into account the UE's reported Tracking Area Identity (TAI).
- TAI Tracking Area Identity
- the Location Area Identity (LAI) returned to the User Equipment (UE) does not need to correspond to an actual Location Area Identity (LAI) used in the CS network.
- LAI Location Area Identity
- the UE's location information e.g. serving MSC/VLR
- Interworking Function It is not necessary for the Interworking Function (IWF) to retrieve any aspects of the User Equipment (UE) Mobility Management (MM) context from the old Mobile Switching Center / Visitor Location Register (MSC/VLR) when the UE performs an inbound Tracking Area Update (TAU) from 2G or 3G. It is also not necessary for the Interworking Function (IWF) to retrieve any information from the old Interworking Function (IWF) in case of a change of Interworking Function (IWF) while the User Equipment (UE) moves within the network.

- MO3 corresponds to the Mobility Management Entity (MME) sending an Uplink Unitdata information to the Mobile Switching Center/ Visitor Location Register (MSC/VLR).
- MSC/VLR Mobile Switching Center/ Visitor Location Register
- An eighth step of the MO procedure corresponds to the Mobility Management Entity (MME) receiving a Downlink Unitdata from the Mobile Switching Center / Visitor Location Register (MSC/VLR).
- a ninth step of the MO procedure designated by MO9, corresponds to the User Equipment (UE) receiving a Downlink NAS Transport information by the Mobility Management Entity (MME).
- the first step MO1 of the MO procedure is only necessary when the UE is in idle mode.
- a User Equipment (UE) in active mode can commence the SMS transfer with the second step MO2 of the MO procedure. This applies to all SMS MO cases.
- UE User Equipment
- the combined MME/IWF sends the short message (in the fourth step MO4) using the existing interface towards the Short Message Service Center (SMSC), as specified in
- SMS-GWMSC Short Message Service Center
- UE User Equipment
- HSS Home Subscriber Server
- MSC/VLR Mobile Switching Center / Visitor Location Register
- a third step of the MT procedure designated by MT3, the Short Message Service Center (SMSC) forwards the short message to the unit providing the Interworking Function (IWF) according to the first embodiment of the present invention, Figure 10.
- a fourth step of the MT procedure designated by MT4, corresponds to the Interworking Function (IWF) sending a paging request to the Mobility Management Entity (MME).

- a twelfth step of the MT procedure designated by MT12, corresponds to the SMS-GMSC of the Short Message Service Center (SMSC) sending a Delivery report to the SC.
- the Mobility Management Entity (MME) paging of the User Equipment (UE) is only necessary when the User Equipment (UE) is in idle mode. For User Equipments (UEs) in active mode, there is no need for the Mobility Management Entity (MME) to perform Paging after the fourth step.
- the Mobility Management Entity (MME) continues with the further seventh step MT7a (i.e. the fifth step MT5 to the seventh step MT7 are skipped).
- the Mobility Management Entity (MME) immediately (i.e. without any paging) sends a Downlink NAS Transport information (eighth step MT8) to the User Equipment (UE). This applies accordingly to all SMS MT cases ( Figures 9 to 12).
- the Interworking Function can be integrated into the Short Message Service Center (SMSC), as depicted for the MT case in figure 12.
- SMSC Short Message Service Center
- the interface as specified in TS23.040 (clause 4.2 "Transfer on reference point 3" according to 3GPP TS 23.040 version 8.5.0) is not needed, while the SGs interface is used between the Mobility Management Entity (MME) and the combined SMSC/IWF for SMS transfer.
- MME Mobility Management Entity
- HSS Home Subscriber Server
- the Interworking Function (IWF) is collocated with the Short Message Service Center (SMSC)
