I-5G ne-Network Slicing
Lapho i-5G ibishiwo kabanzi, ukushibilika kwenethiwekhi kungubuchwepheshe obuxoxwe kakhulu phakathi kwabo. Abasebenza kwinethiwekhi njenge-KT, SK Telecom, China Mobile, DT, DT, KDDI, NTT, kanye neHuawei bonke bakholelwa ukuthi i-Network Slicing iyinhlangano yenethiwekhi efanelekile ye-5G ERA.
Lobu buchwepheshe obusha buvumela abahlinzeki ukuthi bahlukanise amanethiwekhi amaningi okugcina-uku-ukuphela kwingqalasizinda yezemininingwane, futhi inethiwekhi ngayinye yenethiwekhi ihlukaniswe ngokunengqondo kusuka kudivayisi, inethiwekhi yokufinyelela, inethiwekhi yokuhamba kanye nenethiwekhi ehlukene ukuze uhlangabezane nezici ezahlukahlukene zezinhlobo ezahlukahlukene zezinsizakalo.
Kwisilayi ngasinye senethiwekhi, izinsiza ezinikezelwe njengeseva ebonakalayo, i-bandwidth yenethiwekhi, nekhwalithi yensiza kuqinisekisiwe ngokuphelele. Njengoba izingcezu zihlukaniswe komunye nomunye, amaphutha noma ukwehluleka kwesilayidwa ngeke kuphazamise ukuxhumana kwezinye izingcezu.
Kungani i-5G idinga ukuxutshwa kwenethiwekhi?
Kusukela esedlule kunethiwekhi yamanje ye-4G, amanethiwekhi eselula ikakhulukazi akhonza izingcingo eziphathwayo, futhi ngokuvamile enza ukwenziwa okuthile komakhalekhukhwini. Kodwa-ke, e-5G ERA, amanethiwekhi eselula adinga ukusebenzela amadivayisi ezinhlobo ezahlukahlukene nezidingo. Izimo eziningi zezicelo ezishiwo zifaka i-Broadband ye-Mobile Broadband, i-IOT enkulu, kanye ne-Itshur-esibucayi iot. Zonke zidinga izinhlobo ezahlukene zamanethiwekhi futhi zinezidingo ezihlukile ekuhambeni, ezimalini, ezokuphepha, ukulawulwa kwenqubomgomo, i-latency, ukuthembeka nokunye.
Isibonelo, insizakalo enkulu ye-IOT ixhumanisa izinzwa ezihleliwe ukukala lokushisa, umswakama, i-njll. Asikho isidingo sezingcingo, izibuyekezo zendawo, nezinye izici zezingcingo eziphambili ezisebenza kwinethiwekhi yeselula. Ngaphezu kwalokho, izinsizakalo ze-IOT ezibucayi ezibucayi njengokushayela okuzimele kanye nokulawulwa okukude kwamarobhothi kudinga ukuqeda ama-latency ama-milliseconds ambalwa, ahluke kakhulu kwizinsizakalo ze-Broadband Mobile.
Izimo eziphambili zesicelo se-5G
Ngabe lokhu kusho ukuthi sidinga inethiwekhi ezinikezele kwinsizakalo ngayinye? Isibonelo, umuntu usebenzela izingcingo ze-5G, umuntu usebenzela i-IOT enkulu ye-5G, futhi oyedwa ukhonza i-Iot ebucayi ye-5G. Akudingeki, ngoba singasebenzisa i-Network Slicing ukuhlukanisa amanethiwekhi amaningi anengqondo avela kunethiwekhi ehlukile yomzimba, okuyindlela ebiza kakhulu!
Izidingo zohlelo lokusebenza zokusika kwenethiwekhi
Isilayi se-5G senethiwekhi esichazwe ephepheni elimhlophe le-5G elikhishwe yi-NGMN liboniswe ngezansi:
Sisebenzisa kanjani ukuxutshwa kwenethiwekhi okukugcina?
(1) Inethiwekhi engenantambo ye-5G kanye ne-Core Network: NFV
Kunethiwekhi yeselula yanamuhla, idivaysi eyinhloko yifoni ephathekayo. Ran (du and Ru) nemisebenzi eyisisekelo yakhiwa kusuka kumishini yenethiwekhi ezinikezele enikezwe abathengisi be-RAN. Ukuqalisa ukushelela kwenethiwekhi, umsebenzi wenethiwekhi VirtualIzation (NFV) uyimfuneko. Ngokuyisisekelo, umbono oyinhloko we-NFV ukufaka i-software yokusebenza kwenethiwekhi (ie MME, S / P-GW kanye ne-PCRF ku-PAPTE Ngale ndlela, i-RAN iphathwa njengefu lonqenqema, ngenkathi umsebenzi oyisisekelo uphathwa njengefu eliyisisekelo. Ukuxhumeka phakathi kwe-VMS kutholakala emaphethelweni nasefwini elingu-core kulungiselelwe kusetshenziswa i-SDN. Ngemuva kwalokho, kudalwe isicebhu senkonzo ngayinye (ie i-phone slice, isilayidi esikhulu se-IOT, i-IOT ebucayi ye-IOT, njll.).
Ungayisebenzisa kanjani enye yokuxinana kwenethiwekhi (i)?
Isibalo esingezansi sibonisa ukuthi uhlelo ngalunye lwenkonzo lungabonakala kanjani futhi lufakwe kucezu ngalunye. Isibonelo, ukuchela kungalungiswa kanjena:

(4) I-IOT Slicing ye-Mission - Ebucayi
Kuze kube manje, sidinga ukudala izingcezu ezinikezelwe ngezinsizakalo ezinezidingo ezihlukile. Futhi imisebenzi yenethiwekhi ebonakalayo ibekwa ezindaweni ezahlukahlukene kusilayi ngasinye (ie, ifu elinqenqema noma ifu eliyinhloko) ngokuya ngezimpawu zensiza ezahlukahlukene. Ngaphezu kwalokho, eminye imisebenzi yenethiwekhi, njengokukhokhisa, ukulawula inqubomgomo, njll., Kungadingeka kwezinye izingcezu, kodwa hhayi kwabanye. Ama-opharetha angenza ngokwezifiso inethiwekhi ethambisa indlela abafuna ngayo, futhi mhlawumbe ngendlela ebiza kakhulu.
Ungayisebenzisa kanjani enye yokuxinana kwenethiwekhi (i)?
(2) I-Network Slicing phakathi kwama-Edge and Core Cloud: IP / MPLS-SDN
Isoftware echazwe inethiwekhi, yize kuwumqondo olula lapho yenziwa okokuqala, iya ngokuya iba yinkimbinkimbi. Ukuthatha uhlobo lokumbondelana njengesibonelo, ubuchwepheshe be-SDN bunganikeza ukuxhumana kwenethiwekhi phakathi kwemishini ebonakalayo engqalasizinda yenethiwekhi ekhona.
Ukuphela kwenethiwekhi yokugcina
Okokuqala, sibheka ukuthi ungaqinisekisa kanjani ukuthi ukuxhumana kwenethiwekhi phakathi kwefu lonqenqema nemishini evamile yefu ebonakalayo iphephile. Inethiwekhi phakathi kwemishini ebonakalayo idinga ukwenziwa ngokususelwa ku-IP / MPLS-SDN kanye ne-TRONTORY SDN. Kuleli phepha, sigxile kwi-IP / MPLS-SDN enikezwe abathengisi beRouter. I-Nokia and Juniper Bobabili inikeza imikhiqizo yokwakha i-IP / MPLS SDN yenethiwekhi yezokwakha. Ukusebenza kuhlukile kancane, kepha ukuxhumana phakathi kwe-SDN-based VMS kufana kakhulu.
Efwini elingu-core kumaseva abonakalayo. Ku-hypervisor yeseva, sebenzisa i-vroouter / vwitch eyakhelwe ngaphakathi. Isilawuli se-SDN sinikeza ukucushwa komhubhe phakathi kweseva ebonakalayo kanye ne-DC G / W Router (i-Pe Router eyakha ama-MPL L3 VPN eCloud Data Center). Dala imihubhe ye-SDN (okusho ama-MPLS GRE noma Vxlan) phakathi komshini ngamunye obonakalayo (isib. I-5G iot Core) ne-DC G / Wour
Isilawuli se-SDN bese siphatha imephu phakathi kwale migudu kanye ne-MPLS L3 VPN, efana ne-IOT VPN. Inqubo iyefana efwini elinqenqemeni, idala isilayi se-IOT esixhunyiwe efwini eliseceleni kuya kwesihlahla se-IP / MPLS sackbone Le nqubo ingenziwa ngokususelwa kubuchwepheshe namazinga avuthiwe futhi atholakala kuze kube manje.
(3) I-Network Slicing phakathi kwe-Edge and Core Cloud: IP / MPLS-SDN
Okusale manje inethiwekhi ye-fronthawall yeselula. Sisika kanjani le nethiwekhi ye-fronthold yeselula phakathi kwefu elinqenqemeni kanye ne-5G RU? Okokuqala, inethiwekhi yangaphambili ye-5G-haul kumele ichazwe kuqala. Kukhona ezinye izinketho ezikhona ezixoxwayo (isib. Ukwethula inethiwekhi entsha yepakethe esekwe phambili ngokuchaza ukusebenza kwe-du and ru), kepha akukho ncazelo esezingeni esenziwe. Lesi sibalo esilandelayo singumdwebo owethulwe eqenjini le-ITU IMT 2020 elisebenzayo futhi linikeza isibonelo senethiwekhi ye-fronhaul ebonakalayo.
