Evolved NodeB (eNodeB) yog lub hauv paus chaw nres tsheb rau LTE xov tooj cua. Hauv daim duab no, EPC yog tsim los ntawm plaub network cov ntsiab lus : Qhov Chaw Pabcuam (Serving GW), PDNGateway (PDN GW), MME thiab HSS. EPC txuas nrog rau sab nraud tes hauj lwm , uas tuaj yeem suav nrog IP Multimedia Core Network Subsystem (IMS).

Ntxiv mus, LTE core network yog dab tsi?

4 G LTE EPC (Evolved Packet Core ) yog aframework rau muab lub suab converged thiab cov ntaub ntawv ntawm 4G Long-TermEvolution ( LTE ) network . 2g thiab 3g network architectures txheej txheem thiab hloov lub suab thiab cov ntaub ntawv los ntawm ob cais sub-domains: circuit-switched (CS) rau lub suab thiab pob ntawv-hloov (PS) rau cov ntaub ntawv.

Tsis tas li ntawd, HSS yog dab tsi hauv mobile network? Cov HSS (Tsev neeg rau zaub mov hauv tsev) yog qhov sib txuas ntawm HLR (Tsev Chaw Sau Npe) thiab AuC (Authentication Center) - ob lub luag haujlwm tau tshwm sim ua ntej IMS 2G / GSM thiab 3G / UMTS tes hauj lwm . Cov ntaub ntawv kev ruaj ntseg no yog muab rau HLR thiab txuas ntxiv lwm cov koom haum hauv lub network.

Tom qab ntawd, lo lus nug yog, qhov twg network architecture yog LTE?

LTE Network Architecture . Qib siab network architecture ntawm LTE muaj peb yam tseem ceeb hauv qab no: Cov Khoom Siv (UE). Evolved UMSTTerrestrial Radio Access Network (E-UTRAN).

Vim li cas tsis muaj RNC hauv 4g network?

4 G muaj tsis muaj RNC vim nws tau aconverged IP Core thiab cov RNC Cov haujlwm tau hloov mus rau MME uas yog ib feem ntawm ePC.
