•2017: 4G GSM video intercom system raug tso tawm.
4G GSM intercom systemyooj yim nkag mus thiab tawm - tsuas yog hu rau tus lej thiab lub rooj vag qhib.Xauv lub kaw lus, ntxiv, tshem tawm thiab tshem tawm cov neeg siv tau yooj yim siv txhua lub xov tooj.Cov cuab yeej siv xov tooj ntawm tes muaj kev nyab xeeb dua thiab yooj yim rau kev tswj hwm thiab tib lub sijhawm tshem tawm qhov xav tau siv ntau yam, tshwj xeeb rau cov chaw taws teeb tswj thiab cov ntawv tseem ceeb.Thiab txij li tag nrho cov xov tooj tuaj tsis teb los ntawm GSM chav tsev, tsis muaj nqi hu rau cov neeg siv.Intercom system txhawb VoLTE, nyiam kev hu xov tooj kom meej dua thiab kev sib txuas hauv xov tooj sai dua.
VoLTE (Voice over Long-Term Evolution lossis Voice over LTE, feem ntau hu ua lub suab hais lus siab, kuj txhais tau hais tias lub suab hloov mus sij hawm ntev) yog tus qauv kev sib txuas lus ceev ceev rau cov xov tooj ntawm tes thiab cov ntaub ntawv terminals.
Nws yog raws li IP Multimedia Subsystem (IMS) network, uas siv cov profile tshwj xeeb tsim rau lub dav hlau Tswjhwm thiab xov xwm dav hlau ntawm lub suab pabcuam (txhais los ntawm GSM Association hauv PRD IR.92) ntawm LTE.Qhov no tso cai rau lub suab kev pabcuam (tswj thiab txheej txheej xov xwm) xa tawm raws li cov ntaub ntawv kwj hauv LTE cov ntaub ntawv tus neeg nqa khoom network yam tsis tas yuav tsum tau tswj hwm thiab tso siab rau ib txwm hloov pauv lub suab sib txuas.
VoLTE lub suab thiab cov ntaub ntawv muaj peev xwm yog ntau tshaj peb npaug ntawm 3G UMTS thiab ntau dua rau lub sijhawm ntawm 2G GSM.Vim hais tias VoLTE pob ntawv headers yog me dua li qhov tsis zoo VoIP / LTE, lawv kuj ua kom siv tau zoo dua ntawm bandwidth.4G intercom system ua rau VoLTE cov xwm txheej.1.Mobile xov tooj yuav tsum txhawb VoLTE.2.SIM daim npav txhawb VoLTE thiab yuav tsum tau nrog tus kws kho mob hauv xov tooj.3.intercom system module muaj kev txhawb nqa nqa
VoLTE yog dab tsi?
VoLTE (Voice Over LTE) xa cov kev pabcuam suab hauv LTE network, tso cai rau cov neeg siv kom txaus siab rau lub suab hu tau zoo.
