Hoʻopuka ʻo NGN i ka manaʻo o ka waiho ʻana a me ka wehe ʻana, a hoʻohana i ka ʻenehana IP a me ka ʻenehana softswitch e hoʻololi i ka ʻoihana kelepona mai ka ʻenehana i alakaʻi ʻia i ka ʻoihana..
E like me nā mea hou, nui nā pilikia nui o NGN mai ka ʻōnaehana hōʻailona a hiki i ka hoʻolālā ʻana ke ʻimi ʻia nei. Hōʻike ka poʻe akamai i kahi hui o nā maʻi e kali ana i nā kauka maikaʻi e hōʻoia a mālama - palekana pūnaewele, QoS o ka mea lawe pūnaewele, pili pūnaewele, hoʻomohala lawelawe, hoʻokele pūnaewele, hoʻohālikelike, etc..
He aha ka pilina ma waena o NGN a me IP? E like me kā mākou i ʻōlelo ai ma mua, ʻo ka ʻenehana nui o NGN he softswitch, ʻo ia ka hoʻokaʻawale ʻana o ke kelepona a me ka mea lawe, a lawe ʻia ka softswitch e ka pūnaewele IP. Ma kēiaʻano,ʻo ka hoʻomohalaʻana a me ka uluʻana o kaʻenehana IPʻaʻole wale e hoʻoikaika i ka hoʻomohalaʻana i kaʻenehana softswitch, akā, e hoʻoulu i ka hoʻomohalaʻana o NGN.
Ma muli o ka hoʻolālā pūnaewele NGN, hiki ke lawe ʻia nā lawelawe leo kuʻuna a me nā lawelawe multimedia ma luna o nā pūnaewele IP, a e lilo i mea maʻalahi ka hoʻomohala ʻana i ka lawelawe a me ka hoʻolaha. Ua kaupalena nā mea lawelawe kelepona nui a puni ka honua i ka hoʻonui ʻana i kā lākou mau leo leo kuʻuna a ua kūkulu lākou i nā pūnaewele NGN.
Eia nō naʻe, e like me ka hoʻomākaukau ʻana o NGN e hana i nā hoʻolālā nui, ua wikiwiki koke ka hoʻomohala ʻana o nā ʻupena kelepona, a ua hānau ʻia kahi hoʻolālā pūnaewele hou hou no nā hana lawelawe piha, ʻo ia ʻo IMS.
ʻO ka mea i luna nei ka "Next generation network NGN" i lawe ʻia e HDV ʻO Phoelectronʻenehana LTD. ʻO kā mākou hui he mea hoʻohana pūnaewele optical kūikawā e like me nā mea hana hana nui, nā mea pili pūnaewele e pili ana i ka OLT series, ONU series, switch series, optical module series a pēlā aku, eʻoluʻolu e hoʻomaopopo.
