Voice over LTE is the transmission of data associated with voice over a framework based on architecture which delivers relevant IP multimedia services. Similarly, circuit-switched fallback (CSFB) is a technology used in delivering short message service and voice services to devices enabled with LTE using circuit-switched networks and GSM. On the other hand, Simultaneous Voice and LTE (SVLTE) is a technical protocol and standard that enables the usage of both voice and data networks together on the same device using a CDMA voice network and LTE data network. VOLGA (Voice over LTE via Generic Access) is a technological approach used to achieve and deliver short message service as well as voice services alongside LTE networks.

In addition, SRVCC is a technological standard mandatorily required in the voice over LTE systems to allow packet domain calls on LTE devices to transmit data through legacy circuit-switched voice seamlessly. Such legacy circuit-switched voice includes CDMA 1x, GSM, and UMTS, among others. Voice over LTE enables mobile network operators to provide video, rich voice, and efficient messaging services as a main offering. It allows the operators to employ data networks to transmit voice services in relatively small-sized packets. It also aids in increasing the overall efficiency of spectrum and helps in reducing maintenance and operational costs since only one network is used in voice over LTE.
