NGN vs IMS
NGN (Tom ntej no Network) thiab IMS (IP Multimedia Systems) ob leeg yog Platform Architectures siv los ntawm Telecom Operators hauv lawv lub Network. NGN yog txhua tus IP Telecommunication Network muaj peev xwm thauj thiab xa ntau yam kev pabcuam. IMS yog ib qho kev ua haujlwm network tsim ua kom xa cov kev pabcuam Multimedia thiab muaj peev xwm ua haujlwm nrog yuav luag txhua lub network los txhawb kev sib koom ua ke.
NGN yog dab tsi (Next Generation Network)
NGN yog txhua tus IP raws li kev sib txuas ua haujlwm ntawm cov kev pabcuam zoo (QoS) ua rau Traffic Engineered backbone network xa cov kev pabcuam xws li Suab, Fax, Video, Modem Hu, DTMF tones thiab lwm yam. Cov Cheebtsam ntawm NGN tuaj yeem suav nrog Hloov Hloov, Media Gateway, Signaling Gateway, SBC (Session Border Controller) txhawb nqa los ntawm QoS enabled IP / MPLS qaum. Qee qhov qauv tsim ntawm NGN muaj cov khoom siv hauv network xws li DSL Access Multiplexers (DSLAM) lossis Gateway txuas Fiber rau hauv tsev.

A Next Generation Networks (NGN) yog pob ntawv-raws li lub network muaj peev xwm muab Kev Pabcuam Kev Sib Txuas Lus rau cov neeg siv thiab tuaj yeem siv ntau lub broadband, QoS-enabled thauj technologies thiab nyob rau hauv uas cov kev pab cuam muaj nuj nqi yog ywj siab ntawm lub hauv qab kev thauj mus los-txog technologies. Nws ua rau tsis muaj kev nkag mus rau cov neeg siv rau hauv tes hauj lwm thiab sib tw cov chaw muab kev pabcuam thiab cov kev pabcuam uas lawv xaiv. Nws txhawb kev txav mus los dav dav uas yuav tso cai rau cov kev pabcuam zoo ib yam thiab txhua qhov chaw rau cov neeg siv. [ITU-T Cov Lus Pom Zoo Y.2001 (12/2004) – Cov ntsiab lus dav dav ntawm NGN
IMS yog dab tsi (IP Multimedia Systems)
IP Multimedia System yog qhov ua haujlwm tsim nyog rau kev pabcuam multimedia xa khoom hauv Internet raws tu qauv. Yav dhau los AIM ntawm IMS yog kev sib koom ua ke Internet thiab Cellular network kom xa cov kev pabcuam nplua nuj multimedia. IMS tau txhais los ntawm 3GPP (3rd Generation Partnership Project). Tom qab IMS tau txuas ntxiv los ntawm European Telecommunication Standard Institute (ETSI) hauv kev ua haujlwm ntawm NGN Architecture. Tom qab Standardization lub cev ntawm ETSI, TISPAN (Kev sib txuas lus thiab Internet Converged Services thiab Protocols rau Advanced Networking) standardized IMS raws li ib tug subsystem ntawm NGN.
Qhov txawv ntawm IMS Core thiab IMS
Lub ntsiab IMS yog TISPAN Vocabulary thiab IMS yog 3GPP Vocabulary feem ntau txhais rau Mobile Network Convergence rau IP. Core IMS lossis TISPAN IMS feem ntau yog tsom rau kev sib txuas lus.
