24、roup (MSG). Introduction Current eCall is based on CS emergency call in GSM and UMTS networks. LTE spectrum auctions are taking place in the EU and there will be extensive LTE coverage before the implementation of eCall becomes mandatory in 2015. The longevity of GSM networks in the EU over the life

25、time of vehicles is uncertain and GSM spectrum is likely to be re-allocated for UMTS and/or LTE. There is no CS emergency call in LTE. The applicability of the existing technical solution for eCall (in-band modem) should be assessed for VoIP/VoLTE, as well as new technical solutions to be developed

26、that are suitable for packet switched (UMTS and LTE) and offer better performance for eCall for VoIP. Longer term strategies need to be considered and guidance (probably for further work) provided in respect of the long term migration of eCall to support over packet switched networks, and the co-exi

27、stence and possible integration of eCall and other ITS communication equipment installed in vehicles. ETSI ETSI TR 103 140 V1.1.1 (2014-04) 71 Scope The present document contains the findings of STF456. The following areas are addressed: Assessment of in-band modem solution in case of no use of CS b

28、earers. Study the adaptation of IMS emergency call and IMS Multimedia Emergency Service for supporting current and future service required by eCall. Hybrid CS/IMS solution.
