•2017: Kukhishwe uhlelo lwe-intercom yevidiyo ye-4G GSM.
Uhlelo lwe-intercom lwe-4G GSMKulula ukungena nokuphuma - mane ushayele inombolo bese isango liyavuleka. Ukukhiya uhlelo, ukwengeza, ukususa nokumisa abasebenzisi kwenziwa kalula kusetshenziswa noma iyiphi ifoni. Ubuchwepheshe befoni ephathekayo buphephile kakhulu futhi kulula ukuphatha futhi ngesikhathi esifanayo kususa isidingo sokusebenzisa izilawuli ezikude eziningi, ezihloselwe ngokukhethekile kanye namakhadi okhiye. Futhi njengoba zonke izingcingo ezingenayo zingaphendulwa yiyunithi ye-GSM, abasebenzisi abanakho ukushaja ucingo. Uhlelo lwe-Intercom lusekela i-VoLTE, lujabulela ikhwalithi yocingo ecacile kanye nokuxhumeka kocingo okusheshayo.
I-VoLTE (i-Voice over Long-Term Evolution noma i-Voice over LTE, ngokuvamile ebizwa ngokuthi izwi elinencazelo ephezulu, elihunyushwa nangokuthi umphathi wezwi we-long-term evolution) iyindinganiso yokuxhumana engenantambo esheshayo yamafoni aphathwayo kanye nama-terminal edatha.
Isekelwe kunethiwekhi ye-IP Multimedia Subsystem (IMS), esebenzisa iphrofayili eklanyelwe ngokukhethekile indiza yokulawula kanye nendiza yemidiya yesevisi yezwi (echazwe yi-GSM Association ku-PRD IR.92) ku-LTE. Lokhu kuvumela isevisi yezwi (ukulawula kanye nesendlalelo semidiya) ukuthi idluliselwe njengokusakaza kwedatha kunethiwekhi yomphathi wedatha ye-LTE ngaphandle kwesidingo sokugcina nokuthembela kumanethiwekhi wezwi ajwayelekile ashintshiwe ngesekethe.
Umthamo wezwi nedatha ye-VoLTE ungaphezu kokuphindwe kathathu kunowe-3G UMTS kanye nokuphindwe kasithupha kunowe-2G GSM. Ngenxa yokuthi ama-header ephakethe le-VoLTE mancane kune-VoIP/LTE engalungiswanga, asebenzisa futhi i-bandwidth ngendlela ephumelelayo. Uhlelo lwe-intercom lwe-4G luvumela izimo ze-VoLTE. 1. Ucingo oluphathwayo kumele lusekele i-VoLTE. 2. Ikhadi le-SIM lisekela i-VoLTE futhi lidinga ukuba nomhlinzeki wezokuxhumana. Imojula yesistimu ye-3.intercom inenkampani yokusekela
Kuyini i-VoLTE?
I-VoLTE (i-Voice Over LTE) idlulisela izinsizakalo zezwi ngenethiwekhi ye-LTE, okuvumela abasebenzisi ukuthi bajabulele ikhwalithi yekholi yezwi ecacile.
Izici ze-VoLTE
