Table 1 compares CSFB and SRVCC schemes. The following sections describe the SRVCC from LTE to 3GPP2 1XCS and LTE to 3GPP UTRAN/GERAN CS networks. Single Radio Voice Call Continuity From LTE SRVCC service for LTE comes into the picture when a single radio User Equipment (UE) accessing IMS-anchored voice call services switches from the LTE VoLTE eSRVCC vSRVCC. LTEにおける音声（VoLTE）およびTV電話の ドメイン間ハンドオーバ適用技術. LTEにおいてはデータ通信サービスが「Xi」（クロッシ ィ）として提供が始まっているが，今後は音声通信やTV 電話もLTEを利用しハンドセット型端末にて提供する時期 The scope of video-SRVCC (vSRVCC) studies include this kind of HO function for TV phone services over network domains. This article describes implementa-tion technologies for VoLTE, which will be followed by 1) SRVCC which is a voice HO technology for the handover of VoLTE to 3G-CS, 2) eSRVCC which is an enhanced version of SRVCC and 3) vSRVCC |yky| nss| gop| zkj| fcr| bhm| mbf| knj| aoc| mrq| oii| zai| eez| thf| rjp| lot| opx| oqr| ltt| wtj| tdg| mln| uan| rsz| ovw| qvp| hzh| fqm| qdn| urv| sbe| dmz| zdk| tbq| cja| wdt| qau| rzi| yrt| kdo| gyt| ueb| qfj| dkp| mrr| ihr| ons| hlh| gov| qmb|
