srsRAN 4G 23.11/4 wepụtara - OpenSource mmejuputa XNUMXG/LTE tojupụtara

Sistemụ redio sọftụwia Redio Access Network ma ọ bụ ọrụ srsRAN bu n'obi mejuputa ngwugwu 4G/LTE na 5G. Na mbụ, a maara ọrụ ahụ dị ka srsLTE.

Isi mgbanwe tụnyere ụdị nke gara aga:

• Njehie srsUE etinyere na obosara nke 5, 10, 15 na 20 MHz.
• Agbakwunyere algọridim ọhụrụ maka mgbako ugboro ugboro.
• cmake emelitere.
• Ụfọdụ ndozi mperi iji kwalite nkwụsi ike na arụmọrụ.

Isi modul nke srsRAN 4G:

• srsENB (software redio sistemụ eNodeB) - mmejuputa UMTS (Universal Mobile Telecommunications System) Terrestrial Radio Access Network NodeB ma ọ bụ E-UTRAN NodeB ma ọ bụ naanị eNodeB (eNB). N'ezie nke a bụ mmejuputa ngwanrọ nke ọdụ ọdụ 4G/LTE;
• srsUE (ngwaọrụ redio sistemụ ngwanrọ software) - mmejuputa modem 4G/LTE nke nwere ike jikọọ na ọdụ ọdụ eNB;
• srsEPC bụ mmejuputa nke isi netwọkụ, nke gụnyere MME (Mobility Management Entity), HSS (Server Subscriber Server), SGW (Serving Gateway) na PGW (PDN (Packet Data Network) Gateway).

Njirimara igodo:

• mmejuputa nchịkọta nke ma isi ọdụ na modem software;
• ọ ga-ekwe omume ịrụ ọrụ na kaadị SIM software na ngwaike (site na PC/SC) maka srsUE;
• nkwado maka bandwit nke 1.4, 3, 5, 10, 15 na 20 MHz;
• nkwado AES;
• njikarịcha maka SSE4.1/AVX2;
• Mwepụta LTE 10 nkwado;
• Intra-ENB na Inter-ENB nkwado maka eNodeB.

Ọ dị mma ịmara na srsRAN na-etolite na Nkwado O-RAN 5G.

Mgbochi ndị bụ isi

• Enweghị nkwado VoLTE. (Enwere ike itinye VoLTE site na iji IMS nke atọ, dị ka Kamailio, nke dị na kamailio.org site na iji akụkọ a. https://open5gs.org/open5gs/docs/tutorial/02-VoLTE-setup ma otu a ka VoLTE si arụ ọrụ https://www.youtube.com/watch?v=gBX-ZX_d1uY)
• Maka 5G, naanị nkwado maka gNodeB (ọgbọ NodeB na-esote) ka etinyere maka ma CU na DU/RU - ya bụ, ọdụ ntọala, mana etinyeghị modem dị nro.
• Naanị FR1 ka akwadoro.
• Enweghị nkwado 2G ma ọ bụ 3G.

N'adịghị ka Osmocom CNI, srsRAN bu n'obi ịmepụta nchịkọta 4G na 5G maka ịnyefe okporo ụzọ IP. N'otu oge ahụ, Osmocom CNI bụ iji mejuputa 2G na 3G, nke na-elekwasị anya na SMS, USSD na nnyefe olu. Ọ bụ ya mere Osmocom CNI nwere ike ibunye okporo ụzọ olu ọ bụghị naanị na IP-PBX (IP-PBX) dị ka akara mmuke kamakwa, dịka ọmụmaatụ, na-eji E1. iE1usb.
