•2017: Isistimu ye-intercom yevidiyo ye-4G GSM iyakhululwa.
Isistimu ye-intercom ye-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 buvikeleke kakhulu futhi bulula ukuphatha futhi ngesikhathi esifanayo buqeda isidingo sokusebenzisa izilawuli kude namakhadi okhiye amaningi, anezinjongo ezikhethekile.Futhi njengoba zonke izingcingo ezingenayo zingaphendulwa iyunithi ye-GSM, akukho nkokhelo yocingo kubasebenzisi.Isistimu ye-Intercom isekela i-VoLTE, ijabulela ikhwalithi yekholi ecacile kanye nokuxhumeka kwefoni okusheshayo.
I-VoLTE (I-Voice over-Term Evolution noma i-Voice over LTE, evame ukubizwa ngokuthi yizwi elinencazelo ephezulu, elibuye lihunyushwe ngokuthi umthwali wezwi wesikhathi eside) iyindinganiso yokuxhumana engenantambo enesivinini esikhulu yamaselula namatheminali edatha.
Isekelwe kunethiwekhi ye-IP Multimedia Subsystem (IMS), esebenzisa iphrofayela eklanywe ngokukhethekile yendiza Yokulawula kanye nendiza yabezindaba yesevisi yezwi (echazwe yi-GSM Association ku-PRD IR.92) ku-LTE.Lokhu kuvumela isevisi yezwi (isilawuli nesingqimba semidiya) ukuthi sidluliselwe njengokusakaza kwedatha kunethiwekhi yomthwali wedatha ye-LTE ngaphandle kwesidingo sokunakekela nokuncika kumanethiwekhi ezwi ashintshwayo.
Umthamo wezwi nedatha we-VoLTE ungaphezu kokuphindwe kathathu kunowe-3G UMTS futhi uphindwe izikhathi ezingaphezu kweziyisithupha kunowe-2G GSM.Ngenxa yokuthi izihloko zephakethe le-VoLTE zincane kune-VoIP/LTE engalungiselelwe, futhi zisebenzisa kahle kakhulu umkhawulokudonsa.Isistimu ye-intercom ye-4G inika amandla izimo ze-VoLTE.1.Iselula kufanele isekele i-VoLTE.I-2.SIM khadi isekela i-VoLTE futhi idinga ukuba nomhlinzeki we-telecom.I-3.intercom system module inenkampani yenethiwekhi yokusekela
Iyini i-VoLTE?
I-VoLTE (Voice Over LTE) idlulisela izinsiza zezwi ngenethiwekhi ye-LTE, okuvumela abasebenzisi ukuthi bajabulele ikhwalithi yekholi yezwi ecacile.
Izici ze-VoLTE
.0 umsindo ikhwalithi yomsindo ecacile kakhulu
.1 isekhondi ukudayela okusheshayo, akukho ukulinda
I-4G 3G 2G GSM intercom system inika amandla izimo ze-VoLTE
.Iselula kufanele isekele i-VoLTE
.I-SIM khadi isekela i-VoLTE futhi idinga ukuba nomhlinzeki ngocingo
.imojuli yesistimu ye-intercom inenkampani yenethiwekhi yokusekela
