This topic suggest a brief introduction of VOLTE(voice over long term evolution), Accordingly the long term evolution was described by allowing large access rate and less concealment(latency), large efficiency utilizing of radio resource network Which defined less cost transmit bit and proper voice efficiency. All services and application are executed as packet switching domain and circuit switches services are neglected, the one voice substitution was generated by increasing of number of communication ISP (Internet services provider). The solving of problem is IMS based in the conclusion and is defined by 3gpp, which is the best way to communicating with the end-users which provide of reliability, availability, when shifting from current switch circuit to IP (internet protocol) LTE services The GSMA (Global System for Mobile Association) take over the one voice LTE in 2010, and it was supported as many organization, vendors, mobile service providers etc. One voice is generally action performed to obtain a result by GSMA voice over VOLTE solution bases on high performance and acceptance by industry. The IP based services put a various restrictions on services. Quality, air interface by voice over LTE.
