Dispelling some Myths about LTE and IMS SMyth 1: LTE is Data onlyReality: Support of voice was one of the key considerations in designing LTE. The voice solution for LTE is IMS VoIP and it is fully specified.
M th 2 SMS i t supported over LTE t d Myth 2: isntReality: LTE and EPS will support a rich variety of messaging applications - including SMS. The solution is twofold, covering both the full IMS case and a transition solution for those networks that do IMS. not support IMS
Myth 3: IMS isnt ready for prime timeReality: IMS was first developed as part of Rel 5 in 2002. It is based on IETF protocols such as SIP and SDP that are very mature These technologies have been embraced by the industry as the mature. signalling mechanism for multimedia applications.
Myth 4: LTE doesnt support emergency callsReality: VoIP support for emergency calls (incl. location) in Rel 9. A transition solution fall back to 3G/2G - has existed since IMS was introduced (Rel 5).
