Tso tawm free5GC 3.4.0, qhib kev siv ntawm 5G core network Cheebtsam

Ib qhov kev tshaj tawm tshiab ntawm free5GC 3.4.0 qhov project tau tshaj tawm, uas tsim kev qhib kev siv 5G core network Cheebtsam (5GC) ua raws li cov cai ntawm 3GPP Release 15 (R15) specification. Qhov project yog tsim los ntawm National Jiaotong University nrog kev txhawb nqa los ntawm Tuam Tshoj Ministries of Education, Science thiab Economy. Cov cai tau sau rau hauv Go thiab faib raws li Apache 2.0 daim ntawv tso cai.

Txoj haujlwm no suav nrog 5G cov khoom thiab cov kev pabcuam hauv qab no:

  • AMF - Kev Nkag Nkag thiab Kev Tswj Xyuas Mobility.
  • AUSF - Authentication Server Function.
  • CHF - Charging Function.
  • N3IWF - Tsis yog-3GPP Interworking Function.
  • N3IWUE - Tsis yog-3GPP Cov Khoom Siv Siv Ua Haujlwm.
  • NRF - NF Repository Function.
  • NSSF - Network Slice Selection Function.
  • PCF - Txoj Cai thiab Them Nqi.
  • SMF - Session Management Function.
  • SBI - Serviced-Based Interface.
  • UDM - Unified Data Management.
  • UDR - Unified Data Repository.
  • UPF - Tus neeg siv dav hlau muaj nuj nqi.

Ntawm cov kev hloov pauv hauv version 3.4.0:

  • Kev siv SBA (Service-Based Architecture) tau ntxiv kev txhawb nqa rau OAuth kev tso cai raws tu qauv, uas tuaj yeem siv rau hauv txhua qhov kev pabcuam uas twb muaj lawm (AMF, SMF, NRF, PCF, UDR, UDM, AUSF, NSSF) kom siv tau thiab thov kom nkag mus rau token . NRF (Network Repository Function) tivthaiv tau ntxiv lub peev xwm los ua haujlwm raws li kev tso cai server.
  • Ntxiv kev txhawb nqa kom meej meej De-registration. Piv txwv li, tus neeg siv khoom siv xov tooj ntawm tes (UE) tau sau npe nrog AMF qub (Access Management Function) tuaj yeem xa daim ntawv thov rau npe rau AMF tshiab, thiab AMF tshiab no tuaj yeem thov AMF qub kom tsis txhob tso npe.
  • Ntxiv kev txhawb nqa rau kev thov kom hloov txoj kev ("NAS Reroute").
  • UE Configuration Update hais kom ua tau ntxiv kev txhawb nqa rau NITZ (Network Identity and Time Zone) mechanism los hloov lub sijhawm thiab lub sijhawm cov ntaub ntawv rau tus neeg siv lub cuab yeej.

Lwm qhov kev siv thev naus laus zis rau kev xa tawm 5G xov tooj ntawm tes suav nrog NextEPC, OpenAir, Magma, Open5GS, Open5GCore, OAI-CN thiab srsRAN cov haujlwm.
