Despite the difficulty connected to the handover of the 4G network to the 2G/3G network, a telephone communication will not be established on the 4G network. This book analyzes the technologies that have been put in place, such as CSFB (Circuit Service FallBack), an interim solution that enables a mobile co 606 $aLong-Term Evolution (Telecommunications) 606 $aInternet Protocol multimedia subsystem 615 0$aLong-Term Evolution (Telecommunications) 615 0$aInternet Protocol multimedia subsystem. 676 $a621.38456 700 $aPerez$b Andre$0871906 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910824899203321 996 $aVoice over LTE$94097104 997 $aUNINA
