qhov project tso tawm , uas tsim ib pawg qhib rau deploying Cheebtsam ntawm LTE / 4G cellular tes hauj lwm yam tsis muaj cov khoom tshwj xeeb, siv tsuas yog universal programmable transceivers, lub teeb liab duab thiab modulation uas yog teem los ntawm software (SDR, Software Defined Radio). Qhov project code muaj ntawv tso cai raws li AGPLv3.
SrsLTE Kev siv LTE UE (Cov Khoom Siv Khoom Siv, cov neeg siv khoom sib txuas rau kev sib txuas cov neeg siv rau LTE network), LTE chaw nres tsheb hauv paus (eNodeB, E-UTRAN Node B), nrog rau cov ntsiab lus ntawm LTE core network (MME - Mobility Management Entity rau kev sib cuam tshuam nrog cov chaw nres tsheb hauv paus, HSS - Lub Tsev Pabcuam Cov Neeg Siv Khoom Hauv Tsev rau kev khaws cov ntaub ntawv sau npe thiab cov ntaub ntawv hais txog cov kev pabcuam cuam tshuam nrog cov neeg siv khoom, SGW - Kev Pabcuam Gateway rau kev ua thiab xa cov pob ntawv rau cov chaw nres tsheb hauv paus, PGW - Packet Data Network Gateway rau kev txuas tus neeg rau npe mus rau lwm lub network.
Hauv qhov tshiab version:
- Thawj xov tooj cua nkag siv tshuab txhawb nqa LTE MAC, RLC thiab PDCP txheej (Xov tooj cua Tshiab), tsim rau 5G mobile networks;
- Ua raws li tus qauv (Narrowband Internet of Things), siv los txuas autonomous Internet ntawm Yam khoom siv rau lub xov tooj ntawm tes, synchronization code tau ntxiv;
- Ntxiv kev txhawb nqa rau cryptographic algorithms , raws li ZUC kwj cipher;
- srsENB (kev siv chaw nres tsheb hauv paus) tam sim no txhawb nqa thev naus laus zis (Circuit Switched FallBack), uas tso cai rau koj rov qab mus rau 3G thaum hu xov tooj yog tias LTE network tsuas txhawb cov ntaub ntawv hloov pauv hom;
- Ib txheej tau ntxiv los khiav TTCN-3 cov kev xeem kom paub tseeb tias kev ua raws li tus qauv ntawm cov khoom siv los txuas cov neeg siv rau LTE network;
- Tus qauv tshiab rau simulating kev sib txuas lus hauv cov tsheb ciav hlau ceev tau ntxiv rau cov channel simulator;
- RRC thiab NAS cov khaubncaws sab nraud povtseg tau tawm ntawm kev thaiv kev ua haujlwm.
Cov yam ntxwv tseem ceeb:
- Lub kaw lus tuaj yeem ua haujlwm nrog txhua qhov programmable transceivers txhawb nqa los ntawm Ettus UHD (Universal Hardware Driver) thiab bladeRF tsav tsheb thiab muaj peev xwm ua haujlwm ntawm 30.72 MHz bandwidth. srsLTE kev ua haujlwm tau raug sim nrog USRP B210, USRP B205mini, USRP X300, limeSDR thiab bladeRF boards;
- High-speed optimized decoder siv Intel SSE4.1 / AVX2 cov lus qhia kom ua tiav tshaj 100 Mbps kev ua haujlwm ntawm cov khoom siv kho vajtse. Kev siv tus qauv txiav txim siab hauv C lus, muab kev ua haujlwm ntawm qib 25 Mbit / s;
- Tag nrho kev sib raug zoo nrog version 8 ntawm LTE tus qauv thiab ib feem kev txhawb nqa rau qee qhov nta ntawm version 9;
- Muaj kev teeb tsa rau kev ua haujlwm hauv kev faib tawm zaus (FDD) hom;
- Tested bandwidths: 1.4, 3, 5, 10, 15 thiab 20 MHz;
- Txhawb kis tau tus mob hom 1 (ib tug kav hlau txais xov), 2 (hloov ntau haiv neeg), 3 (CCD) thiab 4 (kaw-loop spatial multiplexing);
- Sib npaug nrog kev txhawb nqa rau zaus coding ZF thiab MMSE;
- Kev them nyiaj yug tsim cov kev pabcuam xa cov ntsiab lus multimedia hauv kev tshaj tawm thiab multicast hom;
- Muaj peev xwm tswj xyuas cov cav kom ntxaws nrog rau cov qib thiab debugging dumps;
- MAC qib packet capture system, sib xws nrog Wireshark network analyzer;
- Muaj cov metrics nrog cov ntaub ntawv taug qab hauv hom kab hais kom ua;
- Cov ntaub ntawv nthuav dav configuration;
- Kev siv LTE MAC, RLC, PDCP, RRC, NAS, S1AP thiab GW txheej.
