19 CS Fall back overview CS Fallback allows a LTE UE to drop back to the WCDMA or GSM network if IMS VoIP capabilities are not supported. CS Fallback requires the UE to fallback from E-UTRAN and rather uses either GSM or WCDMA if it must connect to the CS domain. CS Fallback function is of course only possible to realize in areas where E-UTRAN coverage is overlapped with GSM and WCDMA coverage. CS Fallback will always direct the UE to whichever frequency relation has the highest priority. If the same priority is configured for multiple frequencies, the enb will redirect the UE based on a simple Round Robin Algorithm for the load sharing, which is the new enhancement introduced in L12A OI LTE Workshop Commercial in confidence Page 22

20 SMS overview SMSoSGs is an optional feature which enables MO SMS and MT SMS to be relayed via MME to and from the MSC/VLR. The MO SMS and MT SMS are signalled over SGs and do not cause any CS Fallback to GERAN/UTRAN RATs, and consequently does not require any overlapped GERAN/UTRAN coverage. The Network Access Server (NAS) interface is used towards the UE and the SGs interface is used towards the MSC/VLR. MME provides a signaling relay service so that a transparent transfer of SMS between UE and MSC/VLR is possible. OI LTE Workshop Commercial in confidence Page 23
