•Xyoo 2017: 4G GSM video intercom system tau tso tawm.
4G GSM intercom systemyooj yim nkag thiab tawm - tsuas yog hu tus lej thiab lub rooj vag yuav qhib. Xauv lub kaw lus, ntxiv, rho tawm thiab ncua cov neeg siv tau yooj yim siv txhua lub xov tooj. Cov thev naus laus zis 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 lub chaw taws teeb tswj thiab daim npav tseem ceeb. Thiab vim tias txhua qhov kev hu xov tooj tuaj tsis raug teb los ntawm chav tsev GSM, tsis muaj tus nqi hu rau cov neeg siv. Lub kaw lus Intercom txhawb nqa VoLTE, txaus siab rau qhov zoo ntawm kev hu xov tooj thiab kev sib txuas lus sai dua.
VoLTE (Lub Suab hla Kev Hloov Pauv Ntev lossis Lub Suab hla LTE, feem ntau hu ua lub suab txhais siab, kuj txhais ua lub suab ntev) yog tus qauv kev sib txuas lus wireless ceev ceev rau cov xov tooj ntawm tes thiab cov chaw khaws ntaub ntawv.
Nws yog raws li IP Multimedia Subsystem (IMS) network, uas siv cov profile tsim tshwj xeeb rau Control plane thiab media plane ntawm lub suab pabcuam (txhais los ntawm GSM Association hauv PRD IR.92) ntawm LTE. Qhov no tso cai rau lub suab pabcuam (kev tswj thiab media layer) kom xa mus ua cov ntaub ntawv hauv LTE data bearer network yam tsis tas yuav tswj thiab vam khom cov network suab hloov pauv ib txwm muaj.
Lub peev xwm ntawm VoLTE lub suab thiab cov ntaub ntawv yog ntau dua peb npaug ntawm 3G UMTS thiab ntau dua rau npaug ntawm 2G GSM. Vim tias VoLTE pob ntawv headers me dua li VoIP / LTE tsis tau kho kom zoo, lawv kuj siv bandwidth zoo dua. 4G intercom system ua rau VoLTE cov xwm txheej. 1. Xov tooj ntawm tes yuav tsum txhawb nqa VoLTE. 2. Daim npav SIM txhawb nqa VoLTE thiab yuav tsum nyob nrog tus neeg muab kev pabcuam telecom. 3. intercom system module muaj kev txhawb nqa carrier
VoLTE yog dab tsi?
VoLTE (Voice Over LTE) xa cov kev pabcuam suab hla LTE network, ua rau cov neeg siv txaus siab rau qhov zoo ntawm kev hu xov tooj.
Cov yam ntxwv ntawm VoLTE
. 0 suab nrov super meej suab zoo
. Hu xov tooj sai heev hauv 1 vib nas this, tsis tas tos
4G 3G 2G GSM intercom system ua rau VoLTE muaj peev xwm ua haujlwm tau
Xov tooj ntawm tes yuav tsum txhawb nqa VoLTE
Daim npav SIM txhawb nqa VoLTE thiab yuav tsum tau nrog tus neeg muab kev pabcuam telecom.
. Intercom system module muaj kev txhawb nqa carrier
